Acceptance and Commitment Therapy (ACT) for Chronic Pain: A Systematic Review and Meta-Analyses

Effect of third-wave cognitive behavioural interventions on biopsychosocial outcomes in people diagnosed with advanced cancer: A systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

People with advanced cancer experience elevated psychological morbidity and poor quality of life (QoL). The role of third-wave cognitive-behavioural therapy (CBT) interventions in addressing these needs has been examined, but not synthesised in a systematic review. The aim of this review is to systematically identify, analyse and review randomised controlled trials (RCTs) which examined the effect of third-wave CBT interventions on biopsychosocial outcomes (e.g., anxiety, pain, QoL) in this population.

METHODS

A systematic search was undertaken on MEDLINE, PsycInfo, CINAHL, Embase and Cochrane CENTRAL. Studies were included if they examined the effect of third-wave CBT interventions on biopsychosocial outcomes in adults living with advanced cancer in RCTs. The Cochrane Risk of Bias tool assessed risk of bias for each study. A random-effects model was fitted to the data and the restricted maximum-likelihood estimator was applied. The standardised mean differences (SMD) between control and experimental groups at short- and long-term follow up were used.

RESULTS

Twelve RCTs with 782 participants were identified. Meta-analyses demonstrated that third-wave CBT interventions were only more effective than comparator groups in the short-term improvement of QoL (SMD = 0.19, 95 % CI [0.00, 0.37], p < 0.05). The results of the 11 other meta-analyses did not reach statistical significance. Eight studies were classified as having unclear risk, and four were classified as high risk of bias.

CONCLUSIONS

Third-wave CBT interventions may be effective in enhancing QoL in people with advanced cancer. However, more rigorous RCTs are needed to establish their efficacy in this population.

Effects of acceptance and commitment therapy plus exercise for older adults with chronic low back pain: A preliminary cluster randomized controlled trial with qualitative interviews

Chronic low back pain (CLBP) is increasingly prevalent in older adults and often leads to functional disability and depressive symptoms. This 2-arm, double-blinded, pilot cluster RCT, with semi-structured interviews, aimed to evaluate the acceptability, feasibility, and preliminary clinical efficacy of ACT plus exercise training (ACT+Ex) on improving pain-related outcomes, psychological outcomes, and physical fitness in older adults with CLBP at post-treatment and 6-month follow-up. Forty community-dwelling older adults (62-85 years) with CLBP, predominantly female, were randomized to ACT+Ex (n=20) or Education plus exercise program (Edu+Ex) (n=20) for 8 weekly group-based sessions, with assessments at baseline, post-treatment, and 6-month follow-up (primary endpoint). Self-reported outcomes included pain intensity, functional disability (Roland Morris Disability Questionnaires, RMDQ), health-related quality of life (EuroQol-5 Dimensions, EQ-5D-5L), psychological inflexibility (Acceptance and Action Questionnaire-Version 2, AAQ-II), and psychological well-being (Depression Anxiety Stress Scale). Physical fitness was assessed using the functional reach test (FRT), Timed Up and Go test (TUG), 6-minute walk test (6MWT), hand grip strength (HGS), and 30-second sit-to-stand (STS-30) test. This trial achieved high recruitment (23.5 participants per week) and completion rates (92.5%). Exploratory analyses revealed that ACT+Ex significantly improved pain intensity, disability, psychological inflexibility, HRQoL, and physical fitness at post-treatment and 6-month follow-up. Qualitative data identified 3 superordinate themes: previous healthcare experience affecting pain beliefs; acceptance strategies guiding behavioral changes; and facilitators and barriers to treatment compliance. These findings support the need for a definitive RCT and form a valuable basis for future exploration regarding the behavioral mechanisms of ACT in clinical applications. PERSPECTIVE: A multimodal therapy incorporating ACT and exercise promotes positive behavioral changes and its treatment effects are maintained at the 6-month follow-up especially for physical performance.

The Role of Pain Avoidance in the Relation between Pain Intensity and Smoking Cessation Processes

Scientific evidence suggests that smokers who experience varying levels of pain are more likely to maintain their addiction to tobacco. The relationship between pain intensity and cognitive-based smoking processes within a mechanistic framework has received relatively little attention. Pain avoidance may influence the association between pain intensity and smoking, as it is a construct that is related to adverse pain and smoking processes. Thus, the current cross-sectional study examined the indirect effect of pain intensity on three clinically significant smoking processes (i.e., prior quit problems, perceived barriers for cessation, and negative affect reduction smoking expectancies) through pain avoidance among 95 treatment-seeking adult smokers. Regression analyses were conducted using bootstrapping techniques through PROCESS, a conditional modeling program that utilizes an ordinary least squares-based path analytical framework to test for both direct and indirect associations. Results indicated that pain intensity had a statistically significant indirect association with quit problems and perceived barriers for cessation, through pain avoidance. Pain intensity did not have a statistically significant indirect association with the negative affect reduction of smoking expectancies through pain avoidance. The current findings provide evidence for the role of pain avoidance as a potential transdiagnostic mechanism that contributes to maladaptive smoking outcomes within the larger context of the reciprocal model of pain and substance use.

How Does Shame Relate to Clinical and Psychosocial Outcomes in Knee Osteoarthritis?

BACKGROUND

Knee osteoarthritis (OA) is a common and disabling condition that often carries severe psychosocial implications. Chronic illness-related shame has emerged as a substantial psychosocial factor affecting individuals with knee OA, but it is unclear how chronic illness-related shame is associated with the long-term clinical and psychosocial outcomes in individuals with knee OA.

QUESTIONS/PURPOSES

(1) Does a higher level of shame correlate with worse clinical and psychosocial outcomes at baseline among individuals with knee OA? (2) Is a higher level of shame at baseline associated with worse clinical and psychosocial outcomes at 4-month and 12-month follow-up among individuals with knee OA? (3) Are sociodemographic characteristics correlated with levels of shame among individuals with knee OA?

METHODS

Between June 2021 and February 2022, we screened 977 patients based on the inclusion criteria of (1) age 45 years or older, (2) independent in community mobility with or without walking aids, (3) proficient in English or Chinese language, and (4) met the clinical criteria for OA diagnosis outlined by the National Institute for Health and Care Excellence. Of these patients, 47% (460) were eligible and enrolled. A further 53% (517) were excluded for prespecified reasons. Of the 460 enrolled patients, 7% (30) dropped out before data collection began, and 46% (210) of patients did not complete the psychological questionnaires, leaving 48% (220) of patients for analysis. From this final sample, 25% (56) were lost to follow-up at 4 months, and an additional 7% (16) were lost by the 12-month follow-up, leaving 67% (148) of the original eligible group for analysis. All patients were recruited from the outpatient clinics of the orthopaedic and physiotherapy departments across two Singapore hospitals within the National Healthcare Group. The study population had a mean ± SD age of 64 ± 8 years, with 69% (152 of 220) women, and the mean ± SD duration of knee OA symptoms was 6 ± 6 years. Outcome measures used were the Chronic Illness-Related Shame Scale (CISS), the 12-item Knee Injury and Osteoarthritis Outcome Score (KOOS-12), Patient Health Questionnaire 4 (PHQ-4), the 8-item Arthritis Self-Efficacy Scale (ASES-8), and the Brief Fear of Movement Scale (BFOM). The CISS is a validated tool specifically designed to measure feelings of shame (internal and external shame) in individuals living with chronic illness. The scale has been validated for use among patients with knee OA in Singapore. The functional outcome measure used was the Modified Barthel Index. Data on demographic characteristics were collected. Data were collected at baseline, 4-month follow-up, and 12-month follow-up. Statistical analyses included the Spearman correlation, linear regression, and cluster analysis.

RESULTS

At baseline, there was a weak to moderate negative correlation between CISS scores and KOOS-12 and ASES-8 scores (Spearman correlation coefficients ranged from -0.46 to -0.36; all p values < 0.001), indicating that higher levels of shame were associated with slightly to moderately worse knee function and lower self-efficacy. There was a modest positive correlation between CISS scores and PHQ-4 and BFOM scores (the Spearman correlation coefficients ranged from 0.43 to 0.46; all p values < 0.001), indicating that higher levels of shame were linked to more psychological distress and greater fear of movement. At the 4-month follow-up, a higher CISS score at baseline was associated with a decrease in KOOS-12 (adjusted coefficient -0.86 [95% confidence interval (CI) -1.33 to -0.40]; p < 0.001) and ASES-8 (adjusted coefficient -0.12 [95% CI -0.19 to -0.06]; p < 0.001) scores, indicating worsened knee function and reduced self-efficacy over time. Higher CISS scores at baseline were also associated with an increase in PHQ-4 (adjusted coefficient 0.23 [95% CI 0.14 to 0.31]; p < 0.001) and BFOM (adjusted coefficient 0.22 [95% CI 0.08 to 0.36]; p = 0.002) scores at the 4-month follow-up, reflecting greater psychological distress and greater fear of movement. At the 12-month follow-up, a higher CISS score at baseline was associated with a decrease in KOOS-12 (adjusted coefficient -0.72 [95% CI -1.25 to -0.19]; p = 0.008) and ASES-8 (adjusted coefficient -0.12 [95% CI -0.20 to -0.04]; p = 0.002) scores, indicating that those with higher initial levels of shame continued to experience poorer knee function and lower self-efficacy. Higher CISS scores at baseline were also associated with an increase in PHQ-4 (adjusted coefficient 0.13 [95% CI 0.04 to 0.21]; p = 0.004) as well as BFOM (adjusted coefficient 0.20 [95% CI 0.06 to 0.34]; p = 0.007) scores at the 12-month follow-up, indicating ongoing psychological distress and fear of movement. Cluster analysis found that unemployed older patients with lower CISS scores and BMI, as well as having unilateral arthritis and shorter duration of OA, were observed to have better knee function at 4 months (mean difference 7 [95% CI 1 to 12]; p = 0.02) and 12 months (mean difference 7 [95% CI 1 to 13]; p = 0.02) compared with the opposite. After controlling for age, gender, ethnicity, and employment status, the regression analysis found that higher BMI was related to higher CISS scores (adjusted coefficient 0.21 [95% CI 0.07 to 0.34]; p = 0.003).

CONCLUSION

Chronic illness-related shame has a small to modest association with clinical and psychosocial outcomes for individuals with knee OA. Healthcare professionals should routinely incorporate psychosocial assessments to identify and manage shame early, potentially improving both clinical and psychosocial outcomes. Recognizing that higher BMI is linked to increased shame can specifically guide targeted emotional and psychosocial support. Additionally, integrating interventions such as acceptance and commitment therapy and peer support with traditional treatments could enhance adherence and overall patient outcomes, making comprehensive care more effective.

Comparative main effects, mediators, and moderators of cognitive behavioral therapy, acceptance and commitment therapy, and emotional awareness and expression therapy for chronic spinal pain: Randomized controlled trial rationale and protocol

Background

Chronic spinal (back/neck) pain is common and costly. Psychosocial treatments are available but have modest effects. Knowledge of treatment mechanisms (mediators and moderators) can be used to enhance efficacy. Trials that directly compare different treatments are needed to determine which mechanisms are treatment-specific, which are shared across treatments, and which contribute the most to outcomes.

Methods

We will conduct a 4-arm randomized, controlled clinical trial to compare the main effects, mediators, and moderators of three pain therapies: Cognitive-Behavioral Therapy, Acceptance and Commitment Therapy, and Emotional Awareness and Expression Therapy in adults with chronic spinal pain. Following baseline assessment of outcomes variables (two primary outcomes: pain intensity and pain interference) and potential mediators and moderators, we will randomize participants (up to 460) to one of the treatments or usual care control. Treatments will be conducted individually each week for 8 weeks via telehealth. We will conduct weekly assessments of both potential mediators and outcomes, as well as post-treatment and 6-month follow-up assessments. We will test whether any of the therapies is superior to the others (Aim 1); identify mediators that are specific to treatments and those that are shared across treatments (Aim 2); and identify baseline moderators that are specific to treatments or shared across treatments, and moderated mediators of treatments (Aim 3).

Discussion

The findings from this project can be used to improve the effects of psychosocial chronic pain treatments by identifying the most powerful specific and shared mechanisms and revealing for whom the mediator-outcome pathways are strongest.

eBEfree: Combining Psychoeducation, Mindfulness, and Self-Compassion in an App-Based Psychological Intervention to Manage Binge-Eating Symptoms: A Randomized Controlled Trial

OBJECTIVE

To develop and test the effectiveness of the eBEfree program, a 12-session app-based version of a previously tested psychological intervention (BEfree) that combines psycho-education, self-compassion, mindfulness, and Acceptance and Commitment Therapy to reduce binge-eating symptoms.

METHOD

Two-hundred participants with recurrent elevated binge-eating symptoms and a higher body weight were enrolled in a remote parallel-group randomized trial, of which 142 completed the initial assessment (70 in the intervention group). The end-of-treatment and follow-up assessments were conducted 12 weeks after the initial assessment and 26 weeks after the end of treatment, respectively. Intention-to-treat (ITT) analyzes were undertaken using frequentist linear mixed models and Bayesian hierarchical models to test the intervention effectiveness.

RESULTS

43 (waitlist control) and 29 (intervention) participants completed the end-of-treatment assessment, showing a high attrition rate (51%). ITT analyzes showed the eBEfree program to be associated with a significant reduction in binge eating symptomatology from baseline to end-of-treatment (β = -9.49, ρ < 0.0001, g = -1.17), and from end-of-treatment to 26-weeks follow-up (β = -6.01, ρ = 0.04, g = -1.08). At end-of-treatment, the intervention was also associated with a decrease in body mass index and depression symptomatology, as well as an improvement in dimensions of self-criticism and mindfulness. More than 80% of participants rated the quality of the program as positive and helpful.

DISCUSSION

This trial suggests potential benefits of the eBEfree program to help individuals manage symptoms of binge-eating more effectively, reduce weight, and improve well-being and mental health. The intervention benefits should be confirmed in future larger trials.

PUBLIC SIGNIFICANCE

Treating binge-eating (BE) symptoms and associated comorbidities might be challenging for mental health services. Digital and app-based interventions can be a valuable resource to help people manage symptoms and improve well-being and mental health. The current trial suggests the potential benefits of an app-based intervention (eBEfree program) to help people reduce BE symptoms and develop psychological strategies to promote well-being and mental health.

Predicting Clinical Outcomes at the Toronto General Hospital Transitional Pain Service via the Manage My Pain App: Machine Learning Approach

Background

Chronic pain is a complex condition that affects more than a quarter of people worldwide. The development and progression of chronic pain are unique to each individual due to the contribution of interacting biological, psychological, and social factors. The subjective nature of the experience of chronic pain can make its clinical assessment and prognosis challenging. Personalized digital health apps, such as Manage My Pain (MMP), are popular pain self-tracking tools that can also be leveraged by clinicians to support patients. Recent advances in machine learning technologies open an opportunity to use data collected in pain apps to make predictions about a patient's prognosis.

Objective

This study applies machine learning methods using real-world user data from the MMP app to predict clinically significant improvements in pain-related outcomes among patients at the Toronto General Hospital Transitional Pain Service.

Methods

Information entered into the MMP app by 160 Transitional Pain Service patients over a 1-month period, including profile information, pain records, daily reflections, and clinical questionnaire responses, was used to extract 245 relevant variables, referred to as features, for use in a machine learning model. The machine learning model was developed using logistic regression with recursive feature elimination to predict clinically significant improvements in pain-related pain interference, assessed by the PROMIS Pain Interference 8a v1.0 questionnaire. The model was tuned and the important features were selected using the 10-fold cross-validation method. Leave-one-out cross-validation was used to test the model's performance.

Results

The model predicted patient improvement in pain interference with 79% accuracy and an area under the receiver operating characteristic curve of 0.82. It showed balanced class accuracies between improved and nonimproved patients, with a sensitivity of 0.76 and a specificity of 0.82. Feature importance analysis indicated that all MMP app data, not just clinical questionnaire responses, were key to classifying patient improvement.

Conclusions

This study demonstrates that data from a digital health app can be integrated with clinical questionnaire responses in a machine learning model to effectively predict which chronic pain patients will show clinically significant improvement. The findings emphasize the potential of machine learning methods in real-world clinical settings to improve personalized treatment plans and patient outcomes.

Are people with chronic pain more diverse than we think? An investigation of ergodicity

ABSTRACT

This study investigates whether data from people with endometriosis (n = 58) and fibromyalgia (n = 58) exhibit what is called "ergodicity," meaning that results from analyses of aggregated group data can be used to support conclusions about the individuals within the groups. The variables studied here are commonly investigated in chronic pain: pain intensity, pain interference, depressive symptoms, psychological flexibility, and pain catastrophizing. Data were collected twice daily for 42 days from each participant and analyzed in 2 ways: as separate cross-sectional group studies using the timepoints as the separate data sets (between-person) and as individual longitudinal studies using each person's time series data (within person). To confirm ergodicity, the results from the 2 analyses should agree. However, this is not what was observed in several respects. The between-person data showed substantially less variability compared with within-person data. This was evident in both the summary statistics involving single variables and in the correlational analyses. Overall, between-person correlations were relatively restricted in range, while within-person correlations varied widely. These findings have potentially profound implications for the field of chronic pain research. Because ergodicity was not found, this raises doubts around the assumption that aggregated data collected from groups can accurately represent the range of individual experiences in chronic pain. These results advocate for a shift toward inclusion of more individual person-focused approaches as an addition to group-based approaches. This shift could lead to more personalized and effective treatments by better capturing and then clarifying the heterogeneous nature of chronic pain, including the processes that underlie it.

Acceptance and commitment therapy for mild traumatic brain injury (ACTion-mTBI): a quasiexperimental feasibility study

OBJECTIVES

This study aimed to determine the feasibility of recruiting, implementing and delivering an acceptance and commitment therapy (ACT) intervention for mild traumatic brain injury (mTBI) (ACTion-mTBI) within a multidisciplinary outpatient mTBI rehabilitation services. The study also aimed to conduct a preliminary investigation of group differences between ACTion-mTBI and an equivalent cognitive behavioural therapy (CBT) intervention on various outcome measures and psychological treatment targets.

DESIGN

A two-arm quasiexperimental feasibility study.

SETTING

Five mTBI rehabilitation clinics throughout New Zealand.

INTERVENTION

Psychologists working in mTBI rehabilitation clinics throughout New Zealand were trained to deliver ACTion-mTBI or CBT. Eligible participants were assigned to either of these interventions based on the psychologist available at the clinic they were referred to. ACTion-mTBI is a five sessions intervention that incorporates all six components of the ACT model. The CBT intervention is an equivalent intervention and incorporating all four components of the CBT model. Both interventions are adapted for an mTBI context.

PRIMARY OUTCOME MEASURES

The primary outcomes were related to the feasibility of ACTion-mTBI. This included recruitment, retention and treatment adherence of participants, study procedure and fidelity of treatment delivery.

SECONDARY OUTCOME MEASURES

To explore group differences between ACTion-mTBI and CBT on functional disability, postconcussion symptoms, mental health, valued living and psychological flexibility.

RESULTS

The intervention proved feasible to implement with community-based mTBI rehabilitation services. Attrition rates were comparable between the two psychological interventions and fidelity to the treatments was high. At post-treatment, when covarying pretreatment scores, ACTion-mTBI had a significantly greater improvement in functional disability than CBT (moderate effect). ACTion-mTBI also had a significantly greater reduction in postconcussion symptoms, anxiety and stress. Promisingly, significant improvements in psychological flexibility was also found post-treatment. There were no group differences on depressive symptoms and valued living.

CONCLUSION

We conclude that a full clinical trial of ACTion-mTBI for individuals with mTBI is feasible and warranted.

The multidisciplinary team in the management of chronic pain and pain-related fear: an evidence-based approach in a clinical case

PURPOSE

Pain is a complex, intimate, and subjective experience influenced by biological, psychological, and social factors. This case report investigates the effectiveness of a multidisciplinary team approach in addressing chronic pain and pain-related fear.

CASE DESCRIPTION

The case report describes a 22-year-old female who experienced anterior knee pain for seven years, despite undergoing two knee surgeries and physiotherapy without improvement. Following a comprehensive assessment, which included a detailed medical history, clinical examination, and thoughtful clinical analysis, a multidisciplinary approach was recommended. Employing an evidence-based methodology that integrated neurocognitive rehabilitation techniques, including Pain Neuroscience Education, Graded Motor Imagery, and Tactile Discrimination Training, alongside psychological rehabilitation strategies such as Mindfulness, Acceptance and Commitment Therapy, and Problem-Solving Therapy, the report presents a comprehensive in-depth rehabilitation plan exemplifying the application of this multimodal approach within a clinical setting in a patient with chronic pain. This approach is designed not to address the biomechanical aspects but to delve into the cognitive facets associated with pain perception and avoidance, as well as potential psychological factors that may be influencing the onset and persistence of symptoms.

OUTCOMES

The scores from the rating scales provided valuable insights into patient progress in pain management, functional improvement, fear of movement, and overall physical, psychological, and emotional well-being, at six months.

CONCLUSION

This case report offers valuable insights into the usefulness of this multidisciplinary and multimodal approach, highlighting its potential as an avenue in the management of chronic pain and pain-related fear.

Resilience and coping: a qualitative analysis of cognitive and behavioral factors in adults with osteogenesis Imperfecta

PURPOSE

The aim of this qualitative study was to investigate resilience among adults with Osteogenesis Imperfecta (OI).

MATERIALS AND METHODS

Semi-structured interviews were conducted with 15 adults with OI. Transcripts were coded and subsequently abstracted, yielding themes specific to resilience and coping. Interview guides covered broad topics including pain challenges specific to OI, mental health issues related to OI, and priorities for future interventions for individuals with OI.

RESULTS

Participants described resilience in the context of OI as the ability to grow from adversity, adapt to challenges resulting from OI-related injuries, and find identities apart from their condition. Psychological coping strategies included acceptance, self-efficacy, cognitive reframing, perspective-taking, and positivity. Behavioral factors that helped participants develop resilience included developing new skills, pursuing meaningful goals, practicing spirituality, and seeking external resources such as psychotherapy, education, and connection with community.

CONCLUSION

Having identified how adults with OI define resilience and the strategies they use to cope, we can now develop interventions and guide healthcare providers in improving psychological wellbeing in this population.

Experience of Acceptance and Commitment Therapy for those with mild traumatic brain injury (ACTion mTBI): A qualitative descriptive study

Psychological interventions may make a valuable contribution to recovery following a mild traumatic brain injury (mTBI) and have been advocated for in treatment consensus guidelines. Acceptance and Commitment Therapy (ACT) is a more recently developed therapeutic option that may offer an effective approach. Consequently, we developed ACTion mTBI, a 5-session ACT-informed intervention protocol. To establish the feasibility of this intervention, we wanted to understand participants' experiences of ACTion mTBI, determine acceptability and identify any refinements needed to inform a full-scale effectiveness trial. We recruited adults (≥16 years of age) diagnosed with mTBI who were engaged in community-based multidisciplinary rehabilitation. After completing the ACTion mTBI sessions, 23/27 (85.2%) participants (mean time post-injury: 28.0 weeks) completed a semi-structured interview about their experience of the intervention. Interviews were audio-recorded, transcribed verbatim and analysed using a qualitative description approach. There were two overarching themes 1) attacking the concussion from a different direction and 2) positive impact on recovery which depicted participants' overall experiences of the intervention. Within these overarching themes, our analysis also identified two subthemes: 1) helpful aspects of the intervention which included education and ACT processes (i.e., being present and being able to step back) and 2) "contextual factors that enabled intervention effectiveness" which included being equipped with tools, cultural and spiritual responsiveness, the therapeutic connection, and the intervention having a structured yet flexible approach to order of delivery to meet individual needs. Participants' experiences support acceptability, cultural and spiritual responsibility of ACTion mTBI. Suggested refinements included enabling access to intervention over time, not just at one point during recovery and the addition of a brief check-in follow-up.

Knowledge translation initiatives at the Transitional Pain Service: insights from healthcare provider outreach and patient education

Evidence-based treatment of chronic pain requires a multidisciplinary approach grounded in the biopsychosocial model. Implementing this approach within health systems relies on its acceptance by both healthcare providers and patients. While pioneering multidisciplinary pain clinics can serve as a model for implementation, a systematic effort is needed to share knowledge effectively and broadly. In the current paper we provide an overview of the knowledge translation initiatives undertaken at our Transitional Pain Service (TPS) at Toronto General Hospital, a state-of-the-art multidisciplinary pain program established in 2014 for patients at risk of developing chronic pain after surgery. The TPS team strives to enhance acceptance of this model of care among patients and providers, facilitate the establishment of similar clinics, and promote patient understanding of the integrated multidisciplinary pain care approach. Guided by the Knowledge to Action (KTA) framework, knowledge translation activities undertaken by our TPS team include clinician training, resources and outreach activities for providers, and patient education. Resource development was preceded by consultation and needs assessment among patients and providers and feedback from both groups was incorporated as part of the development process. The tailored resources were disseminated via the TPS clinic website and monitoring of online usage enables continuous evaluation of engagement. Barriers to engagement with the resources were examined through patient surveys and staff interviews. Based on these activities, we offer insights gained by our team throughout the knowledge translation process and provide recommendations for other clinical teams who wish to undertake similar initiatives.

Patient Perspectives on the Psychosocial Impact of Chronic Pelvic Pain and Implications for Integrated Behavioral Care Approaches

Chronic pelvic pain (CPP) is a medically complex, multifaceted gynecological condition associated with psychological comorbidities and sexual trauma among women. Low rates of positive treatment outcomes underscore the need to better understand complex relationships between CPP, trauma exposure, and the psychosocial context of patients' lives. We conducted a secondary analysis of English and Spanish qualitative interviews with female-identity patients (N = 48) about CPP's impact on psychosocial well-being. Interviews were coded and analyzed in accordance with reflexive thematic analysis. We generated 4 themes regarding CPP and psychosocial well-being: navigating pain-filled relationships, multiple burdens of mental health challenges and marginalization, sexual trauma exposure embedded in illness experience, and harnessing hope in healing and dealing with CPP. We used insights from these findings to generate a list of treatment recommendations for trauma-informed, CPP-specific integrated care. Patients described the importance of social support and how psychological comorbidities and trauma exposure contributed to CPP's psychosocial toll. Findings provide insight into the burden of CPP-related minority stress and the role of hope on patients' well-being. Patients with CPP endorse the integration of psychosocial support into their CPP treatment plans. The authors encourage the incorporation of behavioral health providers into integrated care teams to deliver trauma-informed, culturally responsive methods for engaging patients with CPP in psychosocial interventions addressing multiple domains of well-being.

Psychometric examination of the Multidimensional Psychological Flexibility Inventory Short Form (MPFI-24) and the Psy-Flex Spanish versions in individuals with chronic pain

BACKGROUND

Acceptance and Commitment Therapy (ACT) has been found to be beneficial for individuals dealing with chronic pain. The theoretical mechanisms of change proposed by ACT are based on the Hexaflex model. To comprehensively reflect this model, the Multidimensional Psychological Flexibility Inventory (MPFI) and Psy-Flex have been developed. The study aimed to adapt the MPFI-24 and the Psy-Flex for Spanish-speaking populations with chronic pain and to examine their dimensionality, internal consistency, convergent validity and incremental validity.

METHODS

This cross-sectional study involved 309 Spanish-speaking adults with chronic pain who completed an online survey. The majority of the participants were women (88.3%). The ages ranged from 18 to 79 years.

RESULTS

Factor analysis showed that the Spanish version of the MPFI-24 has 12 factors, consisting of six flexibility and six inflexibility factors, similar to the original version, but lacking second-order general factors. The Psy-Flex demonstrated a single-factor structure, maintaining the general factor of psychological flexibility seen in the original version. The MPFI-24 showed good internal consistency and adequate convergent validity, with the exception of the Acceptance and Experiential Avoidance subscales. The Psy-Flex showed good internal consistency and convergent validity. Notably, both the MPFI-24 and Psy-Flex scores significantly explained additional variance in psychological distress beyond other ACT-related measures of Hexaflex processes; however, only the Psy-Flex explained pain interference.

CONCLUSIONS

The Spanish adaptations of the MPFI-24 and Psy-Flex are valid and reliable instruments for assessing the Hexaflex model processes in Spanish-speaking adults with chronic pain.

SIGNIFICANCE STATEMENT

Practitioners and researchers in chronic pain will find the Spanish versions of the MPFI-24 and the Psy-Flex here, along with recommendations for their use and scoring based on a robust psychometric rationale. It should be noted that these measures surpass the Chronic Pain Acceptance Questionnaire (CPAQ) and the Psychological Inflexibility in Pain Scale (PIPS), which are considered gold standards in chronic pain assessment.

Self-Determined Sexual Motivation in Persons with Endometriosis and Their Partners: Dyadic Associations of Autonomous and Controlled Sexual Motivations with Sexual and Relational Well-Being and Pain

Endometriosis is a chronic pain condition characterized by the growth of endometrial-like tissue outside of the uterus. Affected individuals and their partners report consequences to sexual functioning, sexual satisfaction, and relationship quality. Previous studies in clinical and non-clinical samples have found that sexual motivation can support or detract from sexual functioning; however, similar investigations are lacking among couples with endometriosis. Informed by self-determination theory, associations between autonomous and controlled sexual motivations with sexual functioning, sexual satisfaction, and relationship satisfaction for persons with endometriosis and their partners, and pain in persons with endometriosis were investigated. Couples (n = 54) completed measures of sexual motivation, sexual functioning, sexual satisfaction, relationship satisfaction, and pain. When persons with endometriosis reported greater autonomous sexual motivation, they were more sexually and relationally satisfied. When persons with endometriosis reported higher controlled sexual motivation, their pain was more unpleasant, and they and their partners were less sexually satisfied. Finally, when partners reported greater controlled sexual motivation, both members of the couple reported significantly lower sexual functioning. While controlled sexual motivation may hinder sexual and relational well-being in couples with endometriosis, autonomous sexual motivation may support them. The findings may inform interventions to promote sexual and relational health in couples with endometriosis.

The Association Between Chronic Pain Acceptance and Pain-Related Disability: A Meta-Analysis

Chronic pain acceptance has been identified as a crucial determinant of functioning among individuals living with chronic pain. However, research examining the relationship between chronic pain acceptance and pain-related disability has revealed variability across studies. The aims of this meta-analysis were to synthesize associations between chronic pain acceptance and pain-related disability, and test the moderating influence of pain characteristics, demographic factors, and methodological variables. Searches of PubMed and PsycINFO electronic databases located 24 studies (N = 6072) reporting correlations between chronic pain acceptance and pain-related disability. Meta-analytic calculations were performed using random effects models. Results indicated a negative association between chronic pain acceptance and pain-related disability that can be characterized as moderate in magnitude (r = -.45) and was stable across pain characteristics and demographic factors. Moderator analyses suggested the association between chronic pain acceptance and pain-related disability may be sensitive to the measures used to assess these constructs. These findings underscore the role of chronic pain acceptance in pain-related disability and reinforce the clinical significance of acceptance-based approaches in enhancing functional outcomes among chronic pain patients.

Acceptance and Commitment Therapy for Hypersexuality: A Pilot Study

Hypersexuality refers to the inability to control sexual desire. Despite it has shown serious consequences for physical, psychological and social health, the evidence of available psychological interventions is still insufficient. In this open-label pilot study, an Acceptance and Commitment Therapy (ACT) intervention was conducted with adults with clinically significant levels of hypersexuality aimed to examine its feasibility and usefulness. The intervention consisted of eight weekly online individual psychological intervention sessions. Outcome self-report measures were administered at baseline, after the intervention and a 3 months follow-up. Behavioral and subjective informed changes in sexual practices were weekly assessed through self-monitoring. Twelve participants (M age = 38.8 ± 11.5 years, 83.3% male, 66.7% homo or bisexual) completed the intervention. The feasibility was found to be good, with all the participants completing the training and high levels of satisfaction. Hypersexuality, psychological flexibility, cognitive fusion and mindfulness scores significantly improved after the ACT intervention, with large effect sizes. Clinically significant changes in hypersexuality were found for the vast majority of participants, besides reductions in the time dedicated to planning and practicing sex and the sexualized drug use. Results indicate that ACT-based interventions may be considered feasible and potentially effective therapeutic alternatives for hypersexuality.

Effectiveness of psychological interventions to decrease cognitive fusion in patients with chronic pain: A systematic review and meta-analysis

OBJECTIVE

While there is sufficient evidence of Acceptance and Commitment Therapy's effectiveness in allowing patients to deal with chronic pain, the effectiveness in cognitive fusion, one of the six core components of the Psychology Flexibility Model, has yet to be established. The aim of this article is to assess whether psychological interventions decrease cognitive fusion.

METHODS

The Web of Science, SCOPUS, Medline, and PsycINFO databases were searched for primary studies up to June 2024. Studies with a cognitive fusion measure in which chronic pain patients received a psychological intervention were included. A methodological quality scale was applied to the selected studies and the average effect sizes (Hedges g) were calculated.

RESULTS

This review included 18 articles with 24 studies (19 pre-post/follow-up studies and five randomized control trials). Cognitive fusion decreased significantly after the intervention. The effect sizes were small/medium at post-test, g = -0.39, p < .001, 95% CI [-0.52, -0.26]; and medium at long-term follow-up, g = -0.55, p < .001, 95% CI [-0.74, -0.36]. A similar tendency was found for studies with RCTs at post-test, g = -0.61, p = .006, 95% CI [-1.05, -0.17], short-term follow-up, g = -0.79, p < .001, 95% CI [-1.18, -0.40] and long-term follow-up, g = -0.58, p = .003, 95% CI [-0.95, -0.20]). Moderator variables such as unemployment, gender, pain intensity, level of depression before the intervention, and duration and intervention modality were identified.

CONCLUSION

Psychological interventions tended to decrease cognitive fusion in chronic pain patients. Nonetheless, more clinical trials are needed to establish the role of cognitive fusion in psychological flexibility.

Is development and persistence of multiple physical symptoms associated with coping? A longitudinal study over a decade

OBJECTIVE

To examine the development and persistence of multiple physical symptoms (MPS) over a decade including the associations with sociodemographics and coping strategies.

METHOD

A longitudinal study of 16,405 individuals aged 20-64 years participating in the Danish Symptom Cohort (DaSC) was conducted in 2012 with follow-up data in 2022 (DaSC II). MPS were assessed according to the unifying diagnostic construct of bodily distress syndrome, and coping was measured with the Brief Approach/Avoidance Coping Questionnaire. Descriptive statistics and multivariable logistic regression analyses were performed.

RESULTS

Among individuals not having MPS in 2012, 17 % had developed MPS in 2022. Among individuals having MPS in 2012, 57 % had persistence of MPS in 2022. Individuals who developed or had persistence of MPS at follow-up were more likely to be female, have lower educational level, be immigrant, redeem antidepressants, have lower approach scores as well as higher diversion and resignation scores.

CONCLUSIONS

Individuals responding to stressful situations with low approach, high diversion, and high resignation may be at higher risk of developing MPS and have persistence of MPS. As coping can be targeted through psychotherapy, it is important to focus on maladaptive strategies, especially in high-risk groups for developing and maintaining MPS.

Adapting behavioral activation for patients receiving medications for opioid use disorder in primary care: a pilot study

Introduction

Effective adjunctive therapeutic treatments for patients with opioid use disorder (OUD) on medication for OUD (MOUD) in primary care settings are needed to address high rates of mental illness and stress. Behavioral activation (BA) is a brief, evidence-based therapy that has potential to improve quality of life in people with OUD. The purpose of this pilot study was to evaluate the feasibility and acceptability of values-based BA (VBA) as an adjunct treatment for patients receiving MOUD in primary care.

Methods

Participants were recruited for a single-arm pilot trial of BA in a primary care setting. VBA was adapted for people with OUD and included 4-6 sessions delivered over 12 weeks with a behavioral health consultant, either in-person or virtually. Feasibility was assessed as recruitment percent and pace and retention percent. Acceptability was assessed with the Client Satisfaction Questionnaire-8 (CSQ-8). Participants completed self-report measures of well-being, depression, substance use, and psychological processes of change at baseline, mid-intervention (6-weeks), and post-intervention (12-weeks). Participants engaged in a brief interview about their experiences at the end of the intervention.

Results

Twenty-one participants enrolled in the intervention (66.7% female, M age = 44.0 years, 19% of those invited). Participants completed an average of 5.1 BA sessions (SD = 1.6) and most (90%) were retained through 12 weeks. Participants rated the intervention as highly acceptable on the CSQ-8 (M = 30.4/32.0, SD = 1.6). In qualitative interviews, participants reported that working with the therapist and setting values-based goals were helpful, while also recommending more tailoring to patients' needs and offering the program early in MOUD treatment. Preliminary efficacy data suggest the program was associated with small to moderate improvements in life satisfaction (Cohen's d = 0.25) and positive affect (d = 0.62), whereas there were no changes in depression (d = 0.09) or negative affect (d = -0.07) in a group with low depression at baseline.

Discussion

VBA adapted for patients on MOUD in primary care was feasible to deliver and acceptable to participants. Minor modifications to the target population and treatment manual could increase the program's impact. Future studies will test the efficacy of the intervention in improving quality of life and OUD treatment outcomes.

Bridging the pain gap after cancer surgery - Evaluating the feasibility of transitional pain service to prevent persistent postsurgical pain - A systematic review and meta-analysis

Background and Aims

The lack of a dedicated pain service catering to the postsurgical period has resulted in the origination of the pain-period gap. This has led to a resurgence of transitional pain service (TPS). Our objective was to evaluate the feasibility of TPS in pain practice among postsurgical cancer patients and its prevention of persistent postsurgical pain (PPSP), culminating in chronic pain catastrophising.

Methods

The protocol for this meta-analysis was registered in the International Prospective Register of Systematic Reviews (ID: CRD42023407190). This systematic review included articles involving all adult cancer patients undergoing cancer-related surgery experiencing pain, involving pharmacological, non-pharmacological and interventional pain modalities after an initial systematic pain assessment by pain care providers across diverse clinical specialities, targeting multimodal integrative pain management. Meta-analysis with meta-regression was conducted to analyse the feasibility of TPS with individual subgroup analysis and its relation to pain-related patient outcomes.

Results

Three hundred seventy-four articles were evaluated, of which 14 manuscripts were included in the meta-analysis. The lack of randomised controlled trials evaluating the efficacy of TPS in preventing PPSP and pain catastrophising led to the analysis of its feasibility by meta-regression. The estimate among study variances τ2 was determined and carried out along with multivariate subgroup analysis. A regression coefficient was attained to establish the correlation between the feasibility of TPS and its patient outcome measures and opioid-sparing.

Conclusion

TPS interventions carried out by multidisciplinary teams incorporating bio-physical-psychological pain interventions have resulted in its successful implementation with improved pain-related patient outcomes mitigating the occurrence of PPSP.

Chronic Pain Psychology in Neurology Practice

OBJECTIVE

This article reviews the latest literature regarding chronic pain epidemiology and describes pain-specific psychological factors associated with the development and maintenance of chronic pain, mental health conditions that co-occur with chronic pain, and advances in the psychobehavioral treatment of chronic pain, including established treatments (ie, cognitive behavioral therapy [CBT], acceptance and commitment therapy, and mindfulness-based stress reduction) and emerging treatments (ie, pain reprocessing therapy).

LATEST DEVELOPMENTS

In addition to CBT and acceptance and commitment therapy for pain, numerous other psychological treatment modalities have been integrated into chronic pain management, including mindfulness-based stress reduction, mindfulness meditation, chronic pain self-management, relaxation response, pain neuroscience education, biofeedback, hypnosis, and, more recently, integrative psychological treatment for centralized pain. This article gives an overview of these methods and contextualizes their use within the standard psychological treatment of chronic pain.

ESSENTIAL POINTS

Guided by the biopsychosocial treatment model, pain psychologists use numerous evidence-based psychological methods to treat patients with chronic pain conditions. Familiarity with the psychological tools available for pain management will aid neurologists and their patients in navigating the psychological aspects of living with chronic pain.

Experiences of patients with chronic low back pain plus comorbid depressive symptoms in a videoconference group acceptance and commitment therapy or behavioral activation treatment for depression: a qualitative study

PURPOSE

To explore the experiences of patients with chronic low back pain (CLBP) plus comorbid depressive symptoms who received a remote synchronous videoconference group form of Acceptance and Commitment Therapy (ACT) or Behavioral Activation Treatment for Depression (BATD).

METHODS

A qualitative study (IMPACT-Q) was nested within a randomized controlled trial (RCT) designed to assess the efficacy and the cost-utility/cost-effectiveness of two therapies in the management of CLBP and depression. Fifty-five patients with CLBP plus depression were selected from the RCT. Twelve focus group sessions, each approximately 60-90 min long, were audio-recorded, transcribed verbatim, and analyzed by six coders through a thematic analysis (deductive and inductive) based on a descriptive phenomenological approach.

RESULTS

Patients perceived behavioral, affective, and cognitive improvements after completing group sessions. Overall, psychotherapy was perceived as a safe and non-judgmental place to express emotions and feel understood. The main barriers reported were lack of human contact and loss of social interaction. In contrast, ease of access, flexibility in the ability to connect from anywhere, avoidance of the need to travel, and savings in time and money were key facilitators to increase attendance and adherence to therapy.

CONCLUSION

This study provided support for the acceptability of videoconference-delivered ACT or BATD in patients with CLBP plus comorbid depressive symptoms.

Associations Between Adult Attachment, Pain Catastrophizing, Psychological Inflexibility and Disability in Adults with Chronic Pain

We investigated whether attachment insecurity (anxiety and avoidance) moderated the association between satisfaction with social support and pain disability. We also tested whether the relationship between insecure attachment and pain disability was serially mediated by pain catastrophising and psychological inflexibility. A large-scale cross-sectional correlational design was employed. Data were collected using an online survey. Correlation, serial mediation and moderated regression analyses were used. Data from 894 people with self-reported chronic pain were analysed. Based on correlations, age, depression, and pain intensity were included as covariates. No direct effect of satisfaction with social support on pain disability was observed in the moderation. Attachment anxiety was positively associated with pain disability (b = 1.20, t = 2.03, p < .05), but attachment avoidance was not (b = -0.08, t = -0.13, p = .90). The association between attachment anxiety and pain disability was partially mediated by pain catastrophising and psychological inflexibility (c = 1.21, t = 4.37, p < .001; a1db2 = 0.33, t = 5.15, p < .001). The relationship between attachment avoidance and pain disability was fully mediated by pain catastrophising and psychological inflexibility (c = 0.15, t = 0.54, p = .59; a1db2 = 0.13, t = 2.24, p < .05). This study provided initial evidence that pain catastrophising and psychological inflexibility mediate the association between insecure attachment and pain disability. Follow-up research using a longitudinal design is recommended.

Acceptance and Commitment Therapy for Adults Living With Inflammatory Bowel Disease and Distress: A Randomized Controlled Trial

INTRODUCTION

The bidirectional relationship between disease activity and mental health in inflammatory bowel disease (IBD) has prompted investigations into the efficacy of psychotherapeutic interventions such as acceptance and commitment therapy (ACT) on biopsychosocial outcomes. We aimed to examine the efficacy of an ACT program (intervention) in comparison with a cognitive behavioral therapy-informed psychoeducation program (active control) for individuals with IBD and coexistent psychological distress. Both programs were delivered online through a hybrid format (i.e., therapist-led and participant-led sessions).

METHODS

A total of 120 adults with IBD were randomized to either the intervention (N = 61) or active control groups (N = 59). Efficacy was determined using linear mixed models for group differences, in rate of changes in study outcomes, between baseline, postintervention, and 3-month follow-up.

RESULTS

The primary outcome health-related quality of life significantly improved in the intervention group when compared with the active control group, with a significantly different rate of change observed from baseline to postintervention ( t [190] = 2.15, P = 0.033) in favor of the intervention group with a medium effect size (β = 0.41, mean difference = 0.07, 95% confidence interval 0.01-0.12, P = 0.014). Similarly, the secondary outcome Crohn's disease activity significantly reduced in the intervention group when compared with the active control group, with a significantly different rate of change observed from baseline to 3-month follow-up ( t [90] = -2.40, P = 0.018) in favor of the intervention group with a large effect size (β = -0.77, mean difference = -9.43, 95% confidence interval -13.72 to -5.13, P < 0.001) ( P = 0.014). Furthermore, when observing the rate of change in outcomes over time for the groups separately, anxiety symptoms and pain significantly improved in the intervention group only, and conversely, ulcerative colitis activity and stress symptoms significantly improved in the active control group only. All other outcomes (N = 14) significantly improved over time in both groups including IBD activity, gastrointestinal unhelpful thinking patterns, visceral anxiety, fatigue interference, fatigue severity, fatigue frequency, psychological inflexibility, self-efficacy, resilience, current health status, depression symptoms, IBD control, and pain catastrophizing; however, these changes were not significantly different between the groups.

DISCUSSION

Both programs were of benefit to people with IBD and distress. However, ACT offers a significant added benefit for health-related quality of life and self-reported Crohn's disease activity and may be a useful adjuvant therapy in integrated IBD care.

Perceived benefits and limitations of a psychoeducation program for patients with fibromyalgia: an interpretative phenomenological analysis

Objective

To analyze the perceived benefits and limitations of a pain psychoeducation program as a non-pharmacological treatment for patients with fibromyalgia.

Methods

An interpretative phenomenological analysis was applied to analyze the subjective experiences of 11 patients with fibromyalgia who participated in a pain psychoeducation program. This program includes educational sessions that address pain understanding, coping strategies, and relaxation techniques. Semi-structured interviews were conducted, transcribed, and analyzed using ATLAS.ti software.

Results

Patients reported significant improvements in cognitive-functional capacity and socio-emotional ability, including better disease understanding and management, emotional stability, and interpersonal relationships. Despite these benefits, they identified limitations in program individualization and insufficient coverage of certain topics, such as sexual health and legal aspects of disability. Enhanced self-management skills were evident, with observed shifts in disease perception and coping strategies.

Conclusion

The psychoeducation program was viewed positively, influencing functional, cognitive, and emotional enhancements. Nonetheless, the need for increased program personalization and expanded socio-economic support was noted. Future research should focus on the long-term impacts of psychoeducation and the feasibility of tailored interventions.

The effects of virtual reality neuroscience-based therapy on clinical and neuroimaging outcomes in patients with chronic back pain: a randomized clinical trial

ABSTRACT

Chronic pain remains poorly managed. The integration of immersive technologies (ie, virtual reality [VR]) with neuroscience-based principles may provide effective pain treatment by targeting cognitive and affective neural processes that maintain pain and therefore potentially changing neurobiological circuits associated with pain chronification and amplification. We tested the effectiveness of a novel VR neuroscience-based therapy (VRNT) to improve pain-related outcomes in n = 31 participants with chronic back pain, evaluated against usual care (waitlist control; n = 30) in a 2-arm randomized clinical trial ( NCT04468074) . We also conducted pre-treatment and post-treatment MRI to test whether VRNT affects brain networks previously linked to chronic pain and treatment effects. Compared with the control condition, VRNT led to significantly reduced pain intensity (g = 0.63) and pain interference (g = 0.84) at post-treatment vs pre-treatment, with effects persisting at 2-week follow-up. These improvements were partially mediated by reduced kinesiophobia and pain catastrophizing. Several secondary clinical outcomes were also improved by VRNT, including disability, quality of life, sleep, and fatigue. In addition, VRNT was associated with increases in dorsomedial prefrontal functional connectivity with the superior somatomotor, anterior prefrontal and visual cortices, and decreased white matter fractional anisotropy in the corpus callosum adjacent to the anterior cingulate, relative to the control condition. Thus, VRNT showed preliminary efficacy in significantly reducing pain and improving overall functioning, possibly through changes in somatosensory and prefrontal brain networks.

Effect of acceptance and commitment therapy-based interventions on mental health and cognitive impairment for patients with advanced colorectal cancer

BACKGROUND

The mental and emotional health of persons diagnosed with cancer is frequently affected. The acceptance and commitment therapy (ACT) is one of the psychological interventions that has proven successful in easing these psychological symptoms and enhancing cancer patients' psychological well-being.

METHODS

A two-arm randomized controlled trial study was utilized, 30 eligible clients with colorectal cancer were chosen randomly and were given ACT therapy at a 1:1 ratio. ACT was delivered in six sessions for 3 weeks, followed by 3 months follow-up.

RESULTS

The table shows a statistically significant increase in the mean scores of the mental health and its flourishing level among the study group than those of the control group. Cognitive impairment was significantly decreased among the study group than for those in the control group.

CONCLUSION

The ACT-based interventions may be a promising approach for improving mental health and cognitive function in cancer patients, particularly those with advanced disease.

Economic Evaluation of Videoconference Group Acceptance and Commitment Therapy and Behavioral Activation Therapy for Depression Versus Usual Care Among Adults With Chronic Low Back Pain Plus Comorbid Depressive Symptoms

Chronic pain and depression are frequently comorbid conditions associated with significant health care and social costs. This study examined the cost-utility and cost-effectiveness of videoconference-based group forms of Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD), as a complement to treatment-as-usual (TAU), for patients with chronic low back pain (CLBP) plus depressive symptoms, compared to TAU alone. A trial-based economic evaluation (n = 234) was conducted from a governmental and health care perspective with a time horizon of 12 months. Primary outcomes were the Brief Pain Inventory-Interference Scale (BPI-IS) and Quality Adjusted Life Year. Compared to TAU, ACT achieved a significant reduction in total costs (d = .47), and BATD achieved significant reductions in indirect (d = .61) and total costs (d = .63). Significant improvements in BPI-IS (d = .73 and d = .66, respectively) and Quality Adjusted Life Year scores (d = .46 and d = .28, respectively) were found in ACT and BATD compared to TAU. No significant differences in costs and outcomes were found between ACT and BATD. In the intention-to-treat analyses, from the governmental and health care perspective, no significant differences in cost reduction and incremental effects were identified in the comparison between ACT, BATD, and TAU. However, in the complete case analysis, significant incremental effects of ACT (∆BPI-IS = -1.57 and -1.39, respectively) and BATD (∆BPI-IS = -1.08 and -1.04, respectively) compared with TAU were observed. In the per-protocol analysis, only the significant incremental effects of ACT (∆BPI-IS = -1.68 and -1.43, respectively) compared to TAU were detected. In conclusion, ACT and BATD might be efficient options in the management of CLBP plus comorbid depression symptoms as compared to usual care. However, no clear difference was found in the comparison between the 2 active therapies regarding cost-effectiveness or cost-utility. PERSPECTIVE: The economic evaluation of psychological therapies for the management of complex conditions can be used in decision-making and resource allocation. This study provides evidence that ACT and BATD are more effective and involve a greater reduction in costs than usual care in the management of CLBP plus comorbid depressive symptoms. TRIAL NUMBER: NCT04140838.

Acceptance and commitment therapy for patients with chronic pain: A systematic review and meta-analysis on psychological outcomes and quality of life

OBJECTIVES

To assess the efficacy of acceptance and commitment therapy (ACT) for patients with chronic pain.

MATERIALS AND METHODS

The research conducted a systematic search of the Cochrane Library, Web of Science, PubMed, EMBASE, PsycINFO, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases following the PRISMA guidelines. The retrieval time limit was from the establishment of the database to October 2023. A meta-analysis was carried out for the randomized controlled trials (RCTs) that meet the inclusion and exclusion criteria by using RevMan 5.3.

RESULTS

Twenty-one RCTs were included. At post-treatment, a significant medium effect size (ES) was found in measuring pain interference, functional impairment, pain acceptance, psychological inflexibility, and depression; Pain intensity, anxiety, and quality of life (QOL) had a small ES. At three months post-treatment, a large ES was found in measuring functional impairment, and a medium ES was found in the other indicators.

CONCLUSION

The researchers provided evidence for the effectiveness of ACT as an intervention for patients with chronic pain, which can be applied by clinicians or nurses in practice. Future research should explore the applicability of ACT to different pain conditions and modalities.

IMPLICATIONS FOR NURSING

Post-treatment data highlight the efficacy of ACT in moderating pain-related outcomes. Clinical nurses are encouraged to incorporate ACT into routine patient education and interventions, including promoting pain acceptance, promoting mindfulness practices, and using cognitive stress reduction techniques. Standardized follow-up after an ACT intervention for patients with chronic pain is critical, including regular assessment, feedback, and realignment of treatment strategies. Overall, ACT became an important tool for nurses to improve the lives of patients with chronic pain.

Study protocol for "Psilocybin in patients with fibromyalgia: brain biomarkers of action"

Background

Chronic pain is a leading cause of disability worldwide. Fibromyalgia is a particularly debilitating form of widespread chronic pain. Fibromyalgia remains poorly understood, and treatment options are limited or moderately effective at best. Here, we present a protocol for a mechanistic study investigating the effects of psychedelic-assisted-therapy in a fibromyalgia population. The principal focus of this trial is the central mechanism(s) of psilocybin-therapy i.e., in the brain and on associated mental schemata, primarily captured by electroencephalography (EEG) recordings of the acute psychedelic state, plus pre and post Magnetic Resonance Imaging (MRI).

Methods

Twenty participants with fibromyalgia will complete 8 study visits over 8 weeks. This will include two dosing sessions where participants will receive psilocybin at least once, with doses varying up to 25mg. Our primary outcomes are 1) Lempel-Ziv complexity (LZc) recorded acutely using EEG, and the 2) the (Brief Experiential Avoidance Questionnaire (BEAQ) measured at baseline and primary endpoint. Secondary outcomes will aim to capture broad aspects of the pain experience and related features through neuroimaging, self-report measures, behavioural paradigms, and qualitative interviews. Pain Symptomatology will be measured using the Brief Pain Inventory Interference Subscale (BPI-IS), physical and mental health-related function will be measured using the 36-Item Short Form Health Survey (SF-36). Further neurobiological investigations will include functional MRI (fMRI) and diffusion tensor imaging (changes from baseline to primary endpoint), and acute changes in pre- vs post-acute spontaneous brain activity - plus event-related potential functional plasticity markers, captured via EEG.

Discussion

The results of this study will provide valuable insight into the brain mechanisms involved in the action of psilocybin-therapy for fibromyalgia with potential implications for the therapeutic action of psychedelic-therapy more broadly. It will also deliver essential data to inform the design of a potential subsequent RCT.

Cognitive Therapy, Mindfulness-Based Stress Reduction, and Behavior Therapy for the Treatment of Chronic Pain: Predictors and Moderators of Treatment Response

Psychosocial interventions for people with chronic pain produce significant improvements in outcomes, but these effects on average are modest with much variability in the benefits conferred on individuals. To enhance the magnitude of treatment effects, characteristics of people that might predict the degree to which they respond more or less well could be identified. People with chronic low back pain (N = 521) participated in a randomized controlled trial which compared cognitive therapy, mindfulness-based stress reduction, behavior therapy and treatment as usual. Hypotheses regarding predictors and/or moderators were based on the Limit, Activate, and Enhance model; developed to predict and explain moderators/predictors of psychosocial pain treatments. Results were: 1) low levels of cognitive/behavioral function at pre-treatment predicted favorable pre- to post-treatment outcomes; 2) favorable expectations of benefit from treatment and sound working alliances predicted favorable pre- to post-treatment outcomes; 3) women benefited more than men. These effects emerged without regard to treatment condition. Of note, high levels of cognitive/behavioral function at pre-treatment predicted favorable outcomes only for people in the treatment as usual condition. Analyses identified a set of psychosocial variables that may act as treatment predictors across cognitive therapy, mindfulness-based stress reduction and behavior therapy, as hypothesized by the Limit, Activate, and Enhance model if these 3 treatments operate via similar mechanisms. Findings point toward people who may and who may not benefit fully from the 3 psychosocial treatments studied here, and so may guide future research on matching people to these kinds of psychosocial approaches or to other (eg, forced-based interventions) non-psychosocial approaches. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT02133976. PERSPECTIVE: This article examines potential predictors/moderators of response to psychosocial treatments for chronic pain. Results could guide efforts to match people to the most effective treatment type or kind.

Acceptance-Commitment Therapy for Women with Episodic Migraine: A Pilot Randomized Trial

Objective: The aim of this study was to conduct a pilot, randomized controlled trial (RCT) of acceptance-commitment therapy (ACT) among women with episodic migraine, aged 18-65 years, and living in the United States. Background: Biobehavioral treatments have recently been proposed as possible preventive therapies for migraine management. ACT is a third wave biobehavioral therapy focused on acceptance and development of psychological flexibility and is evidence based for use in other chronic pain conditions. However, its use for reducing migraine frequency and disability has been understudied to date. Methods: The authors performed a pilot RCT evaluating ACT versus enhanced usual care (EUC) among adult women with episodic migraine. ACT consisted of eight virtual weekly sessions (for 8 weeks). Primary aims evaluated feasibility, retention, and protocol adherence. Secondary clinical outcomes included changes in migraine days and Migraine Disability Assessment (MIDAS). Results: We were able to successfully recruit 54 women in 15 months, which surpassed our recruitment goal. However, the completion rates of migraine logs and questionnaires at both outcome assessments were lower than anticipated. Among the 17 individuals randomized to EUC, 12 (71%) completed migraine logs and 12 (71%) completed questionnaires at the end of the intervention. In the postintervention follow-up, 11 (65%) individuals completed logs and 11 (65%) completed questionnaires. We observed slightly larger decreases in migraine days for those assigned to ACT from baseline to the end of the intervention, but these differences did not persist during postintervention follow-up. Both groups reported similar decreases in MIDAS over time. Conclusions: Recruitment for a large-scale trial of ACT is feasible. Challenges with remote data collection as well as participant burden during the COVID-19 pandemic resulted in lower than anticipated completion rates. Future studies should focus on decreasing participant burden and streamlining study procedures. Clinical Trials Registration: NCT05003362.

Momentary Emotion Regulation Strategies and Pain Experience Among Adults With Chronic Pain: An Ecological Momentary Assessment Study

OBJECTIVES

The intention of this study was to characterize the real-time momentary relationship between emotion regulation strategies and the pain experience (ie intensity, interference, and negative affect) among adults with chronic pain. Chronic pain is a significant public health concern. Psychological treatments are effective for treating chronic pain, but long-term follow-up studies are limited, and treatment effect sizes are small. Identifying modifiable treatment targets, such as emotion regulation (ER), is critical to improve interventions. ER (ie, cognitive and attentional strategies to modulate or maintain emotional experience) has been linked to psychopathology and pain experience in adults. Yet, the existing work is limited and has largely focused on the relationship between emotional experience, not ER, and pain.

MATERIALS AND METHODS

The current study utilized ecological momentary assessment 53 adults with chronic pain. Participants completed ecological momentary assessments of pain experience and ER strategies 5 times a day for 7 days. Associations by specific strategy type were also examined, highlighting the importance of worry, experiential avoidance, rumination, and expressive suppression in pain experience.

RESULTS

Results of the current study provide evidence for the association between within-person maladaptive ER strategies and pain intensity ( b = 2.11, SE = 0.37, P < 0.001), pain interference ( b = 1.25, SE = 0.40, P = 0.002), and pain-related negative affect ( b = 2.20, SE = 0.41, P < 0.001). (77.4% females; M age = 27.10 y, SD = 5.16 y).

DISCUSSION

Given that ER is readily targeted in psychological treatments for chronic pain, the results from the current study provide initial evidence to target these ER strategies in treatment.

Patients' experiences of treatment-relevant processes in multimodal pain rehabilitation for severe complex regional pain syndrome - a qualitative study

PURPOSE

Complex regional pain syndrome (CRPS) is a longstanding condition with spontaneous and evoked pain, that usually occurs in an upper or lower extremity. Although it often resolves within the first year, it may for a minority progress to a chronic and occasionally severely disabling condition. The aim of this study was to explore patients' experiences and perceived effects of a specific treatment, designed for patients with severe and highly disabling CRPS, in order to identify possible treatment-relevant processes.

METHODS

The method used was a qualitative design, using semi-structured interviews with open-ended questions to capture participants' experiences and perceptions. Ten interviews were analyzed using applied thematic analysis.

RESULTS

Despite the fact that participants had a severe conditions, including nerve damage and a long duration of illness, they reported having been helped to increase flexible persistence, reduce fear and avoidance, and improve connections. This helped participants to significant improvements in daily life functioning.

CONCLUSIONS

The participants described distinct possible treatment-relevant processes leading to a substantial improvement in everyday life. The results imply that there is hope for this group that has been severely disabled for many years. This may help guide future clinical treatment trials.

Cross-cultural validity and reliability of the comprehensive assessment of acceptance and commitment therapy processes (CompACT) in people with multiple sclerosis

PURPOSE

The Comprehensive assessment of Acceptance and Commitment Therapy (CompACT) is a 23-item questionnaire measuring psychological flexibility, a quality of life protective factor. An 18-item version was recently produced. We assessed validity and reliability of CompACT, and equivalence of paper and electronic (eCompACT) versions in people with multiple sclerosis (PwMS) in Italy, Germany and Spain.

METHODS

We used confirmatory factor analysis and assessed CompACT-23 and CompACT-18 measurement invariance between the three language versions. We assessed construct validity (Spearman's correlations) and internal consistency (Cronbach's alpha). Test-retest reliability (intraclass correlation coefficient, ICC) and equivalence of paper and eCompACT (ICC and linear regression model for repeated measures) were assessed in subsamples of PwMS.

RESULTS

A total of 725 PwMS completed the study. The three-factor structure of the CompACT-23 showed poor fit (RMSEA 0.07; CFI 0.82; SRMR 0.08), while the fit of the CompACT-18 was good (RMSEA 0.05; CFI 0.93; SRMR 0.05). Configural and partial metric invariance were confirmed, as well as partial scalar invariance (reached when five items were allowed to vary freely). The CompACT-18 showed good internal consistency (all alpha ≥ 0.78); and test-retest reliability (all ICCs ≥ 0.86). Equivalence between paper and eCompACT was excellent (all ICCs ≥ 0.86), with no mode, order, or interaction effects.

CONCLUSION

Results support using the refined CompACT-18 as a three-factor measure of psychological flexibility in PwMS. Paper and eCompACT-18 versions are equivalent. CompACT-18 can be used cross-culturally, but sub-optimal scalar invariance suggests that direct comparison between the three language versions should be interpreted with caution.

A Single-Session Process-Based Cognitive-Behavioral Intervention Combined with Multimodal Rehabilitation Treatment for Chronic Pain Associated with Emotional Disorders

BACKGROUND AND OBJECTIVES

Defined by chronic pain, rheumatic diseases are often co-occurring with anxiety and depression. Among the available psychological interventions, cognitive-behavioral therapies have an already-proven efficiency in these cases. However, the need to adjust their structure became ubiquitous during the post-pandemic period. Hence, the objective of this study was to investigate the impact of a single-session, process-based cognitive-behavioral intervention for patients with rheumatic conditions within an in-patient setting.

MATERIALS AND METHODS

A total of 31 participants (mean age 58.9 years) completed the single-session intervention. Assessments were conducted prior to the intervention, post-intervention and after one month.

RESULTS

Pearson's correlations, paired samples T tests and a covariance analysis based on the Linear Mixed Model were performed for exploring the relations between baseline variables and evaluating the impact of the SSI intervention. Immediately after the intervention, a significant reduction in cognitive fusion (p = 0.001, d = 1.78), experiential avoidance (p = 0.001, d = 1.4) and dysfunctional behavioral processes was observed. At the one-month evaluation, participants reported decreased pain (p = 0.001, d = 1.11), anxiety (p = 0.004, d = 0.55) and depression (p = 0.001, d = 0.72).

CONCLUSIONS

The single-session, process-based approach represents a promising intervention in healthcare contexts, as an integrative part of a multimodal rehabilitation treatment in patients with rheumatic conditions.

Experiences of patients with advanced cancer coping with chronic pain: a qualitative analysis

OBJECTIVES

To gain insight into the perceptions, and beliefs of patients with advanced cancer coping with chronic pain and to identify their attitudes and demands on pain management.

METHODS

From July to September 2022, 17 patients with advanced cancer living with chronic pain were recruited from a tertiary cancer hospital in Hunan Province, China. Qualitative and semi-structured interviews were conducted individually, with 30-45 minutes for each. The Colaizzi 7-step analysis method in phenomenological research was used for data analysis.

RESULTS

The experience of pain acceptance by advanced cancer patients with chronic pain was summarized into four themes: pain catastrophizing (unable to ignore the pain, try various methods to relieve the pain, exaggerating pain perception, and lack of knowledge about proper pain management), rumination (compulsive rumination and worrying rumination), avoidance coping (situational avoidance and repressive avoidance) and constructive action (setting clear value goal and taking reciprocal action).

CONCLUSION

Most patients with advanced cancer had low pain acceptance and negative attitudes. Feeling helpless in the face of pain and suffering alone were their norm. Long-term negative emotions could lead to gradual depression and loss of hope for treatment, resulting in pain catastrophizing and persistent rumination. Nevertheless, a few patients accepted pain with positive attitudes. Medical professionals should pay more attention to the psychological status of advanced cancer patients with chronic pain, and employ alternative therapies, for example, cognitive behavioral therapy. More efforts are needed to reduce patients' pain catastrophizing, and promote their pain acceptance by a better understanding of pain through health education.

Dimensions of psychological flexibility and their significance in people with somatic symptoms: The 18-item Flexibility Index Test (FIT-18)

Psychological flexibility has been hypothesized to preserve health in bad times. We examined whether psychological flexibility as assessed with an abbreviated questionnaire, was indicated to preserve mental and physical health when having somatic symptoms. Principal axis factoring indicated that two dimensions best represented the 60-item Flexibility Index Test (FIT-60) questionnaire: "mindfulness and acceptance" (M&A) and "commitment and behavior change" (C&BC). We selected 18 items that best denoted these dimensions (FIT-18 questionnaire). Regression analyses in 2060 Dutch people with and without persistent somatic symptoms, indicated that the M&A dimension (β = 0.33, p < 0.001) and C&BC dimension (β = 0.09, p < 0.001) were additively associated with mental well-being, but not with physical functioning. Moreover, the M&A dimension was indicated to protect mental well-being when having more severe somatic symptoms (β = 0.11, p < 0.001). The observed differential associations with health suggest the significance for health of the two dimensions of psychological flexibility as assessed with the FIT-18 questionnaire.

Investigation of Predictors of Psychological Resilience in Occupational Therapy Students in Terms of Different Variables

There is an increased number of publications concerning the mental health of occupational therapy students. The aim of this study is to investigate the predictors of psychological resilience in occupational therapy students in terms of different variables. Four scales measuring resilience, psychological flexibility, coping and coping attitudes were used in this study. Predictors of resilience were evaluated using multiple linear regression analysis with the backward elimination. It was determined that psychological resilience, psychological flexibility, and coping attitudes are interrelated concepts (p < 0.05). This is the first study to examine the predictors of the concept of resilience in occupational therapy students in terms of different variables. The results show that students' psychological flexibility and positive coping behaviors need to be improved to develop psychological resilience.

Targeting the endocannabinoid system for the management of low back pain

Low back pain (LBP) is a major unmet clinical need. The endocannabinoid system (ECS) has emerged as a promising therapeutic target for pain, including LBP. This review examines the evidence for the ECS as a therapeutic target for LBP. While preclinical studies demonstrate the potential of the ECS as a viable therapeutic target, clinical trials have presented conflicting findings. This review underscores the need for innovative LBP treatments and biomarkers and proposes the ECS as a promising avenue for their exploration. A deeper mechanistic understanding of the ECS in LBP could inform the development of new pain management strategies.

Examining the Association Between Objective Physical Activity and Momentary Pain: A Systematic Review of Studies Using Ambulatory Assessment

Chronic pain (CP) is a debilitating and increasingly common health condition that adversely impacts function, including physical activity (PA). Research using ambulatory assessment (AA) methods (eg, ecological momentary assessment, actigraphy) offers promise for elucidating the relationship between momentary pain and objective PA in CP populations. This study aimed to systematically review articles assessing the association between momentary pain and PA in adults with CP as measured using AA and to make recommendations for the measurement and study of this relationship. Five databases were systematically searched, and 13 unique records (N = 768) met the inclusion criteria. CP conditions included mixed/nonspecific CP (k = 3), low back pain (k = 2), fibromyalgia (k = 1), unspecified arthritis (k = 1), and hip/knee osteoarthritis (k = 6). The average age of participants across studies was 55.29 years, and the majority identified as women (60.68%) and White (83.16%). All studies measured objective PA via actigraphy, and momentary pain with either a diary/log or ratings on an actigraph. Studies varied in the quantification of PA (ie, activity counts, step count, moderate-vigorous PA), statistical method (ie, correlation, regression, multilevel modeling), and inclusion of moderators (eg, pain acceptance). Studies reported mixed results for the pain-PA relationship. This heterogeneity suggests that no summarizing conclusions can be drawn about the pain-PA relationship without further investigation into its complex nuances. More within-person and exploratory examinations that maximize the richness of AA data are needed. A greater understanding of this relationship can inform psychotherapeutic and behavioral recommendations to improve CP outcomes. PERSPECTIVE: This article presents a systematic review of the literature on the association between momentary pain and PA in adults with CP as measured using AA methods. A better understanding of this nuanced relationship could help elucidate areas for timely intervention and may inform clinical recommendations to improve CP outcomes.

The role of stigma in health and functioning in chronic pain: Not just catastrophizing

BACKGROUND

People with chronic pain are frequently exposed to stigma, which is typically distressing and may lead to internal stigmatizing thoughts. The thought content associated with stigma has similarities to pain catastrophizing, although these concepts differ in that stigma is arguably more social in origin. Stigma can be measured by the Stigma Scale for Chronic Illness - 8-item version (SSCI-8). In this study, we first demonstrate the validity of this measure in Swedish. We then examine the role of stigma in the health and functioning of people with chronic pain, particularly beyond the role played by pain catastrophizing.

METHODS

Adult participants (N = 404) with chronic pain recruited online completed measures of pain, stigma, catastrophizing, pain interference, work and social adjustment and depression on two occasions.

RESULTS

A one-factor solution had an overall good model fit as long as residuals were allowed to covary, indicating some redundancy in the items. The SSCI-8 demonstrated good internal consistency and moderate temporal stability, and SSCI-8 scores demonstrated medium-to-large correlations with the measures of health and functioning. Furthermore, stigma was found to significantly contribute to explained variance in pain interference, work and social adjustment and depression, uniquely adding to the explained variance in these outcomes even after accounting for pain catastrophizing.

CONCLUSIONS

The SSCI-8 provides an adequate measure to capture stigma experiences. Stigma is uniquely associated with pain-related outcomes and should be further considered in pain research and clinical practice in the future.

SIGNIFICANCE

This study points to the importance of a social perspective on pain-related outcomes. We may need to more fully appreciate the way that people with chronic pain are treated by both health care providers and others can have an impact on their well-being. Potential negative impacts of stigmatizing responses to people with chronic pain are highlighted by the current results.

Emotion Regulation and Psychological Dependence on Pain Medication among Hospital Outpatients with Chronic Spinal Pain: The Influence of Rumination about Pain and Alexithymia

Objective: To examine the extent to which pain acceptance, pain catastrophising and alexithymia moderate associations between pain intensity and psychological pain medication dependence. Methods: Participants (106 hospital outpatients with chronic spinal pain) completed the Leeds Dependence Questionnaire (LDQ) to measure psychological dependence on pain medication, and the Chronic Pain Acceptance Questionnaire-8 (CPAQ-8), the Pain Catastrophising Scale (PCS) and the Toronto Alexithymia Scale-20 (TAS-20), plus the Depression, Anxiety and Stress Scale-21 (DASS-21). Results: Multiple linear regression showed that degree of psychological dependence (measured dimensionally across the range of LDQ scores) was associated with TAS subscale difficulty identifying feelings (DIF) (β = 0.249, p = <0.002) and PCS subscale rumination (β = 0.193, p = 0.030), independently of pain intensity and risk behaviors for medication misuse. The effect of pain intensity was moderated by rumination, with pain intensity more strongly associated with dependence when rumination was high (interaction β = 0.192, p = 0.004). Logistic regression showed that the effect of pain intensity on severe dependence (measured categorically as LDQ score ≥ 20) was moderated by alexithymia, so that severe dependence was independently associated with the combination of intense pain and high alexithymia (interaction odds ratio = 7.26, 95% CIs = 1.63-32.42, p = 0.009). Conclusions: Rumination and alexithymia moderated the associations between pain intensity and psychological pain medication dependence, consistent with emotion regulation theory. This raises the possibility that specifically targeting rumination about pain and symptoms of alexithymia could potentially improve the effectiveness of psychological interventions for chronic pain and help people to avoid or reduce their psychological dependence on pain medication.

Acceptance and Commitment Therapy for Chronic Pain: An Overview of Systematic Reviews with Meta-Analysis of Randomized Clinical Trials

This overview of reviews aimed to summarize the evidence from systematic reviews and meta-analyses of randomized clinical trials of the efficacy of acceptance and commitment therapy (ACT) for adults with chronic pain in relation to pain intensity, pain-related functioning, quality of life, and psychological factors. The Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, PsycINFO, PubMed, and the Cochrane Library databases were searched from inception to July 2, 2023. AMSTAR 2 was used to assess the methodological quality of systematic reviews. The overlap among reviews was calculated. Nine reviews comprising 84 meta-analyses of interest were included. At post-treatment, some meta-analyses mainly showed that ACT can reduce depression symptoms, anxiety symptoms, psychological inflexibility, and pain catastrophizing; and can improve mindfulness, pain acceptance, and psychological flexibility. At three-month follow-up, ACT can reduce depression symptoms and psychological inflexibility, as well as improve pain-related functioning and psychological flexibility. At six-month follow-up, ACT can improve mindfulness, pain-related functioning, pain acceptance, psychological flexibility, and quality of life. At six-twelve-month follow-up, ACT can reduce pain catastrophizing and can improve pain-related functioning. Some methodological and clinical issues are identified in the reviews, such as a very high overlap between systematic reviews, the fact that the certainty of the evidence is often not rated and specific details needed to replicate the interventions reviewed are often not reported. Overall, however, randomized clinical trials and systematic reviews show that ACT can improve outcomes related to chronic pain (eg, pain-related functioning). Future systematic reviews should address the methodological and clinical concerns identified here to produce higher-quality findings. PERSPECTIVE: Despite certain methodological and clinical issues, randomized clinical trials and systematic reviews of ACT appear to show that it can improve outcomes related to chronic pain (eg, psychological factors).

Functional neurological disorder: A qualitative study exploring individuals' experiences of psychological services

OBJECTIVES

Individuals with a diagnosis of FND report experiencing stigma in medical settings, however, there is a paucity of research exploring their experiences in psychological services. The aim of this research was to explore experiences of accessing UK psychological services, from the perspective of those with FND.

METHODS

This study utilised a qualitative approach with data collected from semi-structured interviews (n = 15) and analysed using reflexive thematic analysis.

RESULTS

One superordinate theme, 'the stigmatised self within the therapeutic relationship', and five interrelated subthemes were identified: 'internalised stigma and self-doubt', 'selective disclosure to professionals', 'perceptions of psychological explanations', 'having to educate the professionals' and 'attunement and trust within the therapeutic relationship'. Positive therapeutic relationships were perceived to mitigate the impact of these perceived barriers. The conceptualisation of FND and the perception of how this was responded to by services and professionals was a central tenet throughout the related themes.

CONCLUSIONS

Intra-personal, interpersonal and organisational stigma impact access and engagement to psychological treatment. The findings of this study highlight the need for increased training provision for practitioners with a focus on actively challenging FND stigma within services at both an individual and systemic level.

[Evidence-based interventions to treat chronic low back pain: treatment selection for a personalized medicine approach : German version]

INTRODUCTION

Chronic low back pain (cLBP) is highly prevalent in the United States and globally, resulting in functional impairment and lowered quality of life. While many treatments are available for cLBP, clinicians have little information about which specific treatment(s) will work best for individual patients or subgroups of patients. The Back Pain Research Consortium, part of the National Institutes of Health Helping to End Addiction Long-termSM (HEAL) Initiative, will conduct a collaborative clinical trial, which seeks to develop a personalized medicine algorithm to optimize patient and provider treatment selection for patients with cLBP.

OBJECTIVE

The primary objective of this article is to provide an update on evidence-based cLBP interventions and describe the process of reviewing and selecting interventions for inclusion in the clinical trial.

METHODS

A working group of cLBP experts reviewed and selected interventions for inclusion in the clinical trial. The primary evaluation measures were strength of evidence and magnitude of treatment effect. When available in the literature, duration of effect, onset time, carryover effect, multimodal efficacy, responder subgroups, and evidence for the mechanism of treatment effect or biomarkers were considered.

CONCLUSION

The working group selected 4 leading, evidence-based treatments for cLBP to be tested in the clinical trial and for use in routine clinical treatment. These treatments include (1) duloxetine, (2) acceptance and commitment therapy, (3) a classification-based exercise and manual therapy intervention, and (4) a self-management approach. These interventions each had a moderate to high level of evidence to support a therapeutic effect and were from different therapeutic classes.

Benefits, Recruitment, Dropout, and Acceptability of the Strength Back Digital Health Intervention for Patients Undergoing Spinal Surgery: Nonrandomized, Qualitative, and Quantitative Pilot Feasibility Study

BACKGROUND

Patients undergoing spinal surgery report high levels of insecurity, pain, stress, and anxiety before and after surgery. Unfortunately, there is no guarantee that surgery will resolve all issues; postsurgical recovery often entails moderate to severe postoperative pain, and some patients undergoing spinal surgery do not experience (long-term) pain relief after surgery. Therefore, focusing on sustainable coping skills and resilience is crucial for these patients. A digital health intervention based on acceptance and commitment therapy (ACT) and positive psychology (PP) was developed to enhance psychological flexibility and well-being and reduce postsurgical pain.

OBJECTIVE

The objective of this study was 3-fold: to explore the potential benefits for patients undergoing spinal surgery of the digital ACT and PP intervention Strength Back (research question [RQ] 1), explore the feasibility of a future randomized controlled trial in terms of recruitment and dropout (RQ 2), and assess the acceptability of Strength Back by patients undergoing spinal surgery (RQ 3).

METHODS

We used a nonrandomized experimental design with an intervention group (n=17) and a control group (n=20). To explore the potential benefits of the intervention, participants in both groups filled out questionnaires before and after surgery. These questionnaires included measurements of pain intensity (Numeric Pain Rating Scale), pain interference (Multidimensional Pain Inventory), anxiety and depression (Hospital Anxiety and Depression Scale), valued living (Engaged Living Scale), psychological flexibility (Psychological Inflexibility in Pain Scale), and mental well-being (Mental Health Continuum-Short Form). Semistructured interviews combined with log data and scores on the Twente Engagement With eHealth Technologies Scale were used to assess the acceptability of the intervention.

RESULTS

A significant improvement over time in emotional (V=99; P=.03) and overall (V=55; P=.004) well-being (Mental Health Continuum-Short Form) was observed only in the intervention group. In addition, the intervention group showed a significantly larger decline in pain intensity (Numeric Pain Rating Scale) than did the control group (U=75; P=.003). Of the available weekly modules on average 80% (12/15) was completed by patients undergoing spinal fusion and 67% (6/9) was completed by patients undergoing decompression surgery. A total of 68% (17/25) of the participants used the intervention until the final interview. Most participants (15/17, 88%) in the intervention group would recommend the intervention to future patients.

CONCLUSIONS

This pilot feasibility study showed that combining ACT and PP in a digital health intervention is promising for patients undergoing spinal surgery as the content was accepted by most of the participants and (larger) improvements in pain intensity and well-being were observed in the intervention group. A digital intervention for patients undergoing (spinal) surgery can use teachable moments, when patients are open to learning more about the surgery and rehabilitation afterward. A larger randomized controlled trial is now warranted.
