Model and Processes of Acceptance and Commitment Therapy (ACT) for Chronic Pain Including a Closer Look at the Self

The pain and relief of grief: Mental pain and mental pain acceptance associations with post-loss pathologies and growth among young widows and widowers

Mental pain is a core symptom of bereavement, yet its study with grief pathologies is still scarce. Mental pain acceptance may also affect the associations between mental pain, grief pathologies, and post-loss growth (PLG). The current study aims to investigate the associations between mental pain, mental pain acceptance, and post-loss outcomes in a sample of young widow(er)s. 257 young Israeli widow(er)s completed questionnaires assessing mental pain, mental pain acceptance, depression, complicated grief (CG), suicidal risk and PLG. Paths analyses revealed that depression mediated the positive associations between mental pain and suicidal risk and CG, and mental pain acceptance moderated the positive association between mental pain and depression. Mental pain acceptance also moderated the negative association between mental pain and PLG. The study's findings highlight the crucial role of mental pain and mental pain acceptance in the associations between adverse and favorable post-loss outcomes among bereaved individuals.

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.

The Management of Chronic Pain: Re-Centring Person-Centred Care

The drive for a more person-centred approach in the broader field of clinical medicine is also gaining traction in chronic pain treatment. Despite current advances, a further departure from 'business as usual' is required to ensure that the care offered or received is not only effective but also considers personal values, goals, abilities, and day-to-day realities. Existing work typically focuses on explaining pain symptoms and the development of standardised interventions, at the risk of overlooking the broader consequences of pain in individuals' lives and individual differences in pain responses. This review underscores the importance of considering additional factors, such as the influence of chronic pain on an individual's sense of self. It explores innovative approaches to chronic pain management that have the potential to optimise effectiveness and offer person-centred care. Furthermore, it delves into research applying hybrid and individual formulations, along with self-monitoring technologies, to enhance pain assessment and the tailoring of management strategies. In conclusion, this review advocates for chronic pain management approaches that align with an individual's priorities and realities while fostering their active involvement in self-monitoring and self-management.

Web-based training for post-secondary student well-being during the pandemic: a randomized trial

Background: The COVID-19 pandemic has been a highly stressful period where post-secondary education moved to online formats. Coping skills like decentering and reappraisal appear to promote stress resilience, but limited research exists on cultivating these skills in online learning contexts.Methods: In a three-arm randomized trial design, we evaluated three-week, web-based interventions to gauge how to best cultivate mindfulness and stress-reappraisal skills and whether the proposed interventions led to improved mental health. Undergraduate participants (N = 183) were randomly assigned to stress mindset, mindfulness meditation, or mindfulness with choice conditions.Results: At the study level (baseline vs. post-intervention), decentering improved across all conditions. Mindfulness with choice significantly decreased negative affect and rumination compared to stress mindset, while stress mindset significantly enhanced stress mindset skills compared to both mindfulness groups. At the daily level (three sessions per week), stress mindset significantly increased positive affect compared to mindfulness meditation.Conclusions: Results suggest that student mental health can be remotely supported through brief web-based interventions. Mindfulness practices seem to be effective in improving students' negative mood and coping strategies, while stress mindset training can help students to adopt a stress-is-enhancing mindset. Additional work on refining and better matching students to appropriate interventions is needed.

Experiences of internet-based treatment for vulvodynia: A qualitative study

OBJECTIVE

The aim of this study was to describe women's experiences before, under, and after a guided internet-based intervention for vulvodynia.

METHODS

The design was qualitative, based on content analysis. Participants were women who had undergone guided internet-based treatment for vulvodynia based on acceptance and commitment therapy principles (n = 13). Data were collected through in-depth interviews approximately-one month after participants completed treatment.

RESULTS

The analysis revealed the women's experiences of internet-based treatment for vulvodynia. Three themes emerged: "dealing with pain alone," which was related to experiences of living with vulvodynia before internet-based treatment; "finding new ways," which described the experiences of undergoing an internet-based treatment for vulvodynia and "feeling empowered to take control," referring to the experiences of living with vulvodynia after the internet-based treatment. The women described a long search for a diagnosis, revealing a negative experience of healthcare. The internet-based treatment helped them find new ways to manage vulvodynia, but difficulties with the treatment were also experienced. After the intervention, the women reported improvements in wellbeing and having better strategies to manage pain, but also stated that the treatment was insufficient to perceive changes in vulvar pain.

CONCLUSIONS

The guided internet-based treatment program for vulvodynia based on acceptance and commitment therapy principles was perceived as credible, helpful to manage vulvodynia, and could serve as a complement to regular care. Questions regarding the need for more support and optimal length of treatment need to be further evaluated.

Internet-based Treatment for Vulvodynia (EMBLA) - A Randomized Controlled Study

BACKGROUND

Internet-based ACT (Acceptance and commitment therapy) treatment may improve accessibility and reduce stigma related to seeking health care, but there are a lack of studies investigating internet-based treatment using ACT principles for women with vulvodynia.

AIM

The aim of this study was to investigate the effects of an internet-based treatment of pain during intercourse for women with provoked vulvodynia compared with no intervention during the waiting period before clinical treatment.

METHODS

A multicenter randomized controlled trial was conducted during 2016 to 2020, in which 99 participants were included. Participants were randomized to either a 6 week guided internet-based treatment using ACT principles or usual care. Data were collected at baseline, 6 weeks after baseline, and approximately 10 months after baseline.

OUTCOMES

Pain-related (pain during intercourse, tampon test, impact of pain on sexual function) and pain behavior-related outcomes (attempts at intercourse, sexual activities besides intercourse, willingness to perform the tampon test, chronic pain acceptance questionnaire) were used as outcomes.

RESULTS

Treatment was efficacious in what concerns pain during intercourse and pain acceptance. Less pain during intercourse among women in the intervention group was observed at both post-treatment (primary endpoint, P = .01, Cohen's d = 1.4, 95% CI = 0.33, 2.4), and follow-up (P = .04). Absolut mean difference between groups for pain during intercourse at post-treatment was -2.84, (95 % CI = -4.91, -0.78), and -1.58 at follow-up, (95 % CI = -3.17, 0.02), where the intervention group rated less pain than controls. No differences between groups over time were found for tampon test measures or impact of pain on sexual function. There was a significant difference between groups at all timepoints indicating fewer attempts at intercourse among participants in the intervention group. At post-treatment, women who underwent internet-based treatment reported higher pain acceptance and a rise in activity engagement compared with the control group.

CLINICAL IMPLICATIONS

There is an indication that internet-based treatment could be incorporated into clinical practice as a complement to clinical treatment.

STRENGTHS & LIMITATIONS

Study strengths included using several forms of recruitment and an intervention built by different professions with long experience of treating patients with vulvodynia. High dropout rate was a limitation of this study.

CONCLUSION

Internet-based treatment may have an impact on pain during intercourse and positive effects on pain acceptance. However, conclusions must be drawn with caution due to the small sample size.

Measuring 'self': preliminary validation of a short form of the Self Experiences Questionnaire in people with chronic pain

BACKGROUND

People with chronic pain often struggle with their sense of self and this can adversely impact their functioning and well-being. Acceptance and Commitment Therapy particularly includes a process related to this struggle with self. A measure for this process, the Self Experiences Questionnaire (SEQ), was previously developed in people with chronic pain.

PURPOSE

The aim of the current study was to validate a shorter version of the SEQ in people with chronic pain to reduce respondent burden and facilitate further research.

METHODS

Data from 477 participants attending an interdisciplinary pain management programme were included. Participants completed measures of treatment processes (self-as-context, pain acceptance, cognitive fusion and committed action) and outcomes (pain, pain interference, work and social adjustment and depression) at baseline and post-treatment. Confirmatory factor analysis was used for item reduction. Correlations between scores from the shorter SEQ and other process and outcome variables were calculated to examine validity. Change scores of the shorter SEQ and their correlations with changes in outcome variables were examined for responsiveness.

RESULTS

An eight-item SEQ (SEQ-8) scale including two factors, namely Self-as-Distinction and Self-as-Observer, emerged, demonstrating good reliability (Cronbach's α = .87-.90) and validity (|r| = .14-.52). Scores from SEQ-8 significantly improved after the treatment (d = .15-21), and these improvements correlated with improvements in most outcomes.

CONCLUSIONS

The SEQ-8 appears to be a reliable and valid measure of self. This shorter format may facilitate intensive longitudinal investigation into sense of self and functioning and well-being.

Acceptance and Commitment Therapy for chronic pain on functioning: A systematic review of randomized controlled trials

Chronic pain is a worldwide health problem, Acceptance and Commitment Therapy (ACT) is regarded as one of the promising interventions. ACT aims to help chronic pain patients to create space for pursuing valued life activities in spite of pain. This systematic review of randomized controlled trials (RCTs) examined the efficacy of ACT on functioning for chronic pain. Literature search was performed among seven databases, and 12 RCTs were retrieved. The revised Cochrane risk of bias tool (RoB 2.0) was employed to assess the quality of the 12 RCTs, of which 10 were rated as "low risks", and 2 as "some concerns". Effect sizes of single RCTs and the pooled effect sizes of meta analyses were all rated by Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Low to moderate evidence showed that ACT played a positive immediate role in functioning for patients with chronic pain; however, it is inconsistent whether the effect can be sustained. More RCTs are warranted within specific chronic pain conditions.

Differences in adaptive and maladaptive psychosocial responses to chronic pain among adults with varying physical activity levels

AIM

Chronic pain is a global public health problem that detrimentally impacts people's health and well-being. Physical activity is beneficial and a recommended self-management strategy for adults living with chronic pain. Yet, many of them struggle to meet the public health recommendation of 150+ minutes/week of moderate-vigorous physical activity. Identifying modifiable factors related to physical activity participation is needed. Adaptive (i.e., self-regulatory efficacy to overcome pain and related barriers [SRE-pain], psychological flexibility) and maladaptive (i.e. pain anxiety) responses were the modifiable factors examined in the present study. The purpose was to investigate whether adults living with chronic pain who were sufficiently active, insufficiently active or inactive significantly differed in their adaptive and maladaptive responses to chronic pain.

METHODS

Adults with self-reported chronic pain for 6+ months (N = 318) completed an online survey that measured physical activity, psychological flexibility, SRE-pain and pain anxiety. Sufficiently active (n = 139), insufficiently active (n = 91) and inactive (n = 88) groups were identified.

RESULTS

A significant multivariate analysis of covariance (MANCOVA) (p < .001) with univariate follow-up tests illustrated that the sufficiently active individuals reported the highest psychological flexibility and SRE-pain compared to insufficiently active and inactive individuals (p's < .001). Overall, sufficiently active participants responded the most adaptively and least maladaptively to their pain, followed by the insufficiently active. Inactive participants responded the most maladaptively.

CONCLUSION

Identifying differences in adaptive and maladaptive responses to pain highlights possible modifiable factors to target in future physical activity intervention research that focuses on improving chronic pain self-management.

Internet-based treatment for vulvodynia (EMBLA) - Study protocol for a randomised controlled study

BACKGROUND

Vulvodynia is defined as vulvar pain for at least 3 months without a clear cause. To the best of our knowledge, there are no trials investigating the effects of internet treatment using CBT (Cognitive behavioural therapy) treatment with Acceptance and Commitment Therapy (ACT) components for women with vulvodynia. The aim of this study is to examine the effects of such a guided internet-based intervention on provoked vulvar pain during the waiting period before clinical treatment.

METHODS

We will randomise 52 patients to either guided internet-based intervention with CBT with (ACT) components or no intervention during the waiting period for treatment as usual. Online assessments are conducted at baseline, posttreatment, and at follow-up after 9 months. The primary outcome measure is provoked vulvar pain. Secondary outcomes are depression, anxiety, sexual function, and quality of life. Linear-mixed effect models will be used to assess the effect of the internet-based intervention on vulvar pain, pain acceptance, depression, anxiety, sexual function, and quality of life over time, by applying the intention-to-treat approach. Continuous data will be analysed with general linear models using intention-to-treat and also per protocol approaches to assess the effects of the intervention at different time points. Ordinal and binary data will be analysed with Mann Whitney's test, Fischer's exact test and multivariate logistic regression, respectively.

DISCUSSION

As a randomised controlled trial with short- and long-term follow-up points, the EMBLA study intends to provide a novel and better understanding regarding the treatment of vulvodynia and the role of internet-based treatment as a complement to standard care for women suffering from vulvodynia. The effects of vulvodynia on pain, sexual function, quality of life, depression, and anxiety are investigated. The study's results are expected to be of value in the planning of clinical care in the medical area. High dropout rates and technical difficulties associated with using the platform are common in similar studies.

Acceptance and commitment therapy for chronic pain conditions on functioning: A systematic review protocol

AIM

To explore the efficacy of acceptance and commitment therapy (ACT) on chronic pain in terms of functioning; and to identify the most promising modes and patterns for implementing ACT.

DESIGN

Systematic review and meta-analysis.

METHODS

We will include randomized controlled trials which focus on the efficacy of ACT on chronic pain conditions with functioning as the primary outcome. Seven databases have been searched and grey literature will also be systematically searched for. Eligible studies will be screened. The newly revised Cochrane risk of bias tool will be used to assess the quality of the included studies. Data will be extracted, and meta-analyses will be performed within specific condition groups of chronic pain. Meta-regression and subgroup analyses will be employed to identify the efficacious modes and patterns for implementing the therapy. Grading of Recommendations Assessment, Development, and Evaluation approach will be applied to reach a convincing conclusion. The study has been funded since July 2018.

DISCUSSION

This systematic review aims to explore the efficacy of ACT for chronic pain on functioning based on the latest evidence. The most promising manners will be identified for designing and delivering the therapy. An accurate, transparent, and standardized review process is expected by adhering to the instructions of relevant guidelines.

IMPACT

Chronic pain is prevalent worldwide and reduced functioning is one of the leading consequences. With the anticipated evidence of high level, this research attempts to examine the role of acceptance and commitment therapy, a promising psychological intervention, in the management of chronic pain for improving individual's functioning status. The systematic review may contribute to a more convincing and targeted conclusion compared with the existing studies of its kind.

Psychosocial Factors in Painful Diabetic Neuropathy: A Systematic Review of Treatment Trials and Survey Studies

OBJECTIVE

Diabetes mellitus is associated with a number of complications that can adversely impact patients' quality of life. A common and often painful complication is painful diabetic neuropathy. The aims of this study were to systematically review and summarize evidence from studies of psychological treatments and psychosocial factors related to painful diabetic neuropathy and assess the methodological quality of these studies.

METHODS

Electronic databases, related reviews, and associated reference lists were searched. Summaries of participants' data relating to the efficacy of psychological treatments and/or to associations between psychosocial factors and outcomes in painful diabetic neuropathy were extracted from the included studies. The methodological quality of included studies was assessed using two standardized quality assessment tools.

RESULTS

From 2,921 potentially relevant titles identified, 27 studies were included in this systematic review. The evidence suggests that depression, anxiety, sleep, and quality of life are the most studied variables in relation to pain outcomes in painful diabetic neuropathy and are consistently associated with pain intensity. The magnitude of the associations ranged from small to large.

CONCLUSIONS

Research into psychosocial factors in painful diabetic neuropathy is unexpectedly limited. The available evidence is inconsistent and leaves a number of questions unanswered, particularly with respect to causal associations between variables. The evidence reviewed indicates that depression, anxiety, low quality of life, and poor sleep are associated with pain in painful diabetic neuropathy. The disproportionate lack of research into psychological treatments for painful diabetic neuropathy represents a significant opportunity for future research.

Pain acceptance in cancer patients with chronic pain in Hunan, China: A qualitative study

Objective

The purpose of this qualitative study was to describe the experiences of pain acceptance in Chinese cancer patients with chronic pain.

Methods

Twelve hospitalized cancer patients with chronic pain participated in this qualitative descriptive study from August to November 2017. In-person semi-structured interviews were conducted, recorded, transcribed, and analyzed using Colaizzi's seven-step method.

Results

The following four main themes and 15 subthemes emerged. Theme 1 (adaptation): pain is overwhelming and pain relief is a top priority, avoidance of pain-inducing factors, and resignation; theme 2 (emotional reactions to pain): feeling misunderstood, hopelessness, frustration, irritability, and concern for loved ones; theme 3 (functional limitations): daily life activities, social communication, and work; theme 4 (coping strategies): pharmacological therapies, behavioral strategies, social support strategies, and spiritual strategies.

Conclusions

This study provides a description of cancer patients' experiences related to the need for pain acceptance. These findings provide insight into the essential role of pain acceptance and underline the need to apply acceptance-based cognitive behavioral interventions as adjunctive non-pharmacological alternatives for chronic cancer pain.

Acceptance and Commitment Therapy for the Treatment of Chronic Pain and Coexisting Depression: A Single-Case Study

Pain resulting from chronic medical conditions (CMCs) can create debilitating effects globally across domains of functioning in the lives of those it impacts. There currently remain no treatment options to eliminate associated pain entirely, leaving care efforts often to manage the disabling effects and consequential depression. Acceptance and commitment therapy (ACT) has recently been introduced as an alternative treatment approach, emphasizing the commitment to engage in actions that contribute to a fulfilling life even in the face of disability through the fostering of psychological flexibility. For patients who do not respond to traditional psychological approaches, ACT may offer a sensible substitute. This single-case study delineates ACT for chronic pain and comorbid depression using standardized and patient-centered outcome measures across areas of general symptom functioning, therapeutic processes, and flexibility surrounding pain associated with CMCs. Clinical significance and reliable change were calculated using the reliable change index, in conjunction with patient-reported behavioral engagement and subjective assessment. Results indicate significant improvement across areas of depression, psychological flexibility, and flexibility in relating to pain endured from CMCs. The patient reported perceived improvement in quality of life and no longer viewed herself as a “professional patient.” This case study illustrates the potential of shifting from restraining and extinguishing symptoms to fostering a stance of willingness to reengage in a valued life while continuing to live with CMCs.

The acceptance and commitment therapy model in occupational rehabilitation of musculoskeletal and common mental disorders: a qualitative focus group study

Aims: The aim of this study was to examine whether and how intended processes of behavioural change were reflected in participants' experiences after an inpatient occupational rehabilitation programme. The programme was transdiagnostic, lasted 3½ weeks and was based on the acceptance and commitment therapy model.Methods: Twenty-two participants (17 women and 5 men) took part in five qualitative focus group interviews after the programme. Analysis was data-driven, categorising participants' experiences using an initial explorative phenomenological approach. The emerging data-driven categories were re-contextualised within the theoretical framework of the therapy model.Results: The participants referred to experiences within all three intended domains of the model (openness, awareness, and engagement). Our results indicate that the transdiagnostic approach may have facilitated openness, while the attainment of flexible self-awareness was less evident. Participants expressed engagement and behavioural changes linked to personal values, but did not mention actions leading to imminent return to work.Conclusions: The results imply that for implementation in occupational rehabilitation, further development of this model is needed specifically regarding processes related to self-awareness and committed action towards work. These findings are relevant for the interpretation of results from randomised clinical trials on acceptance and commitment therapy in occupational rehabilitation.Implications for rehabilitationAcceptance and commitment therapy seems to be a feasible component in an occupational rehabilitation programme for persons with different diagnoses.A transdiagnostic approach mixing musculoskeletal pain disorders and common mental disorders in the same rehabilitation programme seems to facilitate the process of openness and acceptance.There is a need to further develop and operationalise some of the processes in Acceptance and commitment therapy to accommodate the approach to the occupational rehabilitation context.

Are We Speaking the Same Language? Finding Theoretical Coherence and Precision in "Mindfulness-Based Mechanisms" in Chronic Pain

Objective

Over the past 50 years, the field of chronic pain has witnessed an evolution of psychological approaches with some notable success. Some of this evolution has included "mindfulness-based interventions" (MBIs), now regarded as having encouraging partial support for their effectiveness. However, several theoretical challenges remain that may inhibit the progress of MBIs. These challenges include a lack of clarity surrounding the mindfulness construct itself, the proliferation of purported underlying mechanisms arising from different theories, and limited evidence for the mechanisms through which MBIs work. The current conceptual review provides a critique of existing theoretical models of mindfulness that have been applied to understanding and treating chronic pain.

Design

A conceptual narrative review was conducted.

Setting

Treatment programs for people with chronic pain.

Patients

Individuals with any type of chronic pain.

Interventions

MBIs for chronic pain.

Outcome Measures

Mindfulness-based mechanisms explored in relation to several domains of functioning.

Results and Conclusions

Based on this assessment, a summary of available evidence for a particular contextual behavioral theory of "mindfulness"-psychological flexibility-is outlined. Findings show the need for further integration of existing mindfulness constructs to better guide development and evaluation of mindfulness-based treatment methods in the future.

Association Between Psychological Interventions and Chronic Pain Outcomes in Older Adults: A Systematic Review and Meta-analysis

IMPORTANCE

Chronic noncancer pain (hereafter referred to as chronic pain) is common among older adults and managed frequently with pharmacotherapies that produce suboptimal outcomes. Psychological treatments are recommended, but little information is available regarding their efficacy in older adults.

OBJECTIVE

To determine the efficacy of psychological interventions in older adults with chronic pain and whether treatment effects vary by participant, intervention, and study characteristics.

DATA SOURCES

MEDLINE, Embase, PsycINFO, and the Cochrane Library were searched from inception to March 29, 2017.

STUDY SELECTION

Analysis included studies that (1) used a randomized trial design, (2) evaluated a psychological intervention that used cognitive behavioral modalities alone or in combination with another strategy, (3) enrolled individuals with chronic pain (pain ≥3 months) with a sample mean age of 60 years or older, and (4) reported preintervention and postintervention quantitative data.

DATA EXTRACTION AND SYNTHESIS

Two of the authors independently extracted data. A mixed-model meta-analysis tested the effects of treatment on outcomes. Analyses were performed to investigate the association between participant (eg, age), intervention (eg, treatment mode delivery), and study (eg, methodologic quality) characteristics with outcomes.

MAIN OUTCOMES AND MEASURES

Pain intensity was the primary outcome; secondary outcomes included pain interference, depressive symptoms, anxiety, catastrophizing beliefs, self-efficacy for managing pain, physical function, and physical health.

RESULTS

Twenty-two studies with 2608 participants (1799 [69.0%] women) were analyzed. Participants' mean (SD) age was 71.9 (7.1) years. Differences of standardized mean differences (dD) at posttreatment were pain intensity (dD = -0.181, P = .006), pain interference (dD = -0.133, P = .12), depressive symptoms (dD = -0.128, P = .14), anxiety (dD = -0.205, P = .09), catastrophizing beliefs (dD = -0.184, P = .046), self-efficacy (dD = 0.193, P = .02), physical function (dD = 0.006, P = .96), and physical health (dD = 0.160, P = .24). There was evidence of effects persisting beyond the posttreatment assessment only for pain (dD = -0.251, P = .002). In moderator analyses, only mode of therapy (group vs individual) demonstrated a consistent effect in favor of group-based therapy.

CONCLUSIONS AND RELEVANCE

Psychological interventions for the treatment of chronic pain in older adults have small benefits, including reducing pain and catastrophizing beliefs and improving pain self-efficacy for managing pain. These results were strongest when delivered using group-based approaches. Research is needed to develop and test strategies that enhance the efficacy of psychological approaches and sustainability of treatment effects among older adults with chronic pain.

Rationale and design of a pilot study examining Acceptance and Commitment Therapy for persistent pain in an integrated primary care clinic

Most of the 100 million Americans with persistent pain are treated in primary care clinics, but evidence-based psychosocial approaches targeting pain-related disability are not usually provided in these settings. This manuscript describes the rationale and methods for a protocol to pilot test the feasibility and effectiveness of Acceptance and Commitment Therapy (ACT), an evidence-based psychological treatment for persistent pain, delivered by a Behavioral Health Consultant in primary care. Eligible patients are identified through electronic health record registries and invited to participate via secure messaging, letters and a follow-up phone call. Participants are also recruited with advertising and clinician referral. Patients agreeing to participate are consented and complete initial assessments, with a target of 60 participants. Randomization is stratified based on pain severity with participants assigned to either ACT or Enhanced Treatment as Usual (E-TAU). ACT participants receive one standardized Behavioral Health Consultation visit followed by three ACT-based group visits and one group booster visit. All patients attend six assessment visits, during which the E-TAU patients are provided with educational pain management handouts based on standard cognitive behavioral treatment of pain. The study aims to determine feasibility and effectiveness of brief ACT for persistent pain delivered by an integrated behavioral health clinician in primary care from pre- to post-treatment, and to examine mechanisms of change in ACT participants. This study, in a "real-world" setting, will lay groundwork for a larger trial. If effective, it could improve treatment methods and quality of life for patients with persistent pain using a scalable approach.

Perceived injustice in chronic pain: an examination through the lens of predictive processing

Chronic pain conditions have been shown to be exacerbated by psychological factors, and a better understanding of these factors can inform clinical practice and improve the efficacy of interventions. The current paper investigates perceived injustice, a novel psychosocial construct, within a framework influenced by the tenets of predictive processing. The proposed conceptual model derived from tenets of predictive processing yields a single hierarchical self-reconfiguring system driven by prediction, which accounts for a wide range of human experiences such as perception, behavior, learning and emotion. This conceptualization can inform the development and implementation of more targeted therapeutic interventions for chronic pain.

Relationship between psychological inflexibility and experiential avoidance and internet addiction: Mediating effects of mental health problems

Internet addiction became a major mental health problem in college student. Our objective was to examine the relationship between psychological inflexibility and experiential avoidance (PIEA) and Internet addiction (IA) and the mediating effects of mental health problem indicators. 500 college students (238 men and 262 women) participated in this study. The level of PIEA was examined using the Acceptance and Action Questionnaire-II. The severity of IA was assessed using the Chen Internet Addiction Scale. The levels of depression, anxiety, interpersonal sensitivity, and hostility were evaluated using the Symptom Checklist-90 item-Revised Scale. The relationship among PIEA, mental health problems, and IA was examined using structural equation modeling. The severity of PIEA was positively associated with the severity of IA as well as positively associated with the severity of mental health problems. In addition, the severity of mental health problem indicators was positively associated with the severity of IA. These results provide the severity of PIEA is directly related to the severity of IA and indirectly related to the severity of IA through increasing the severity of mental health problems. The PIEA should be one of the target objectives when administer cognitive-behavioral therapy to college students with IA and mental health problems.

Cost-Utility of Group Acceptance and Commitment Therapy for Fibromyalgia Versus Recommended Drugs: An Economic Analysis Alongside a 6-Month Randomized Controlled Trial Conducted in Spain (EFFIGACT Study)

The aim of this study was to analyze the cost utility of a group-based form of acceptance and commitment therapy (GACT) in patients with fibromyalgia (FM) compared with patients receiving recommended pharmacological treatment (RPT) or on a waiting list (WL). The data were derived from a previously published study, a randomized controlled trial that focused on clinical outcomes. Health economic outcomes included health-related quality of life and health care use at baseline and at 6-month follow-up using the EuroQoL and the Client Service Receipt Inventory, respectively. Analyses included quality-adjusted life years, direct and indirect cost differences, and incremental cost effectiveness ratios. A total of 156 FM patients were randomized (51 GACT, 52 RPT, 53 WL). GACT was related to significantly less direct costs over the 6-month study period compared with both control arms (GACT €824.2 ± 1,062.7 vs RPT €1,730.7 ± 1,656.8 vs WL €2,462.7 ± 2,822.0). Lower direct costs for GACT compared with RPT were due to lower costs from primary care visits and FM-related medications. The incremental cost effectiveness ratios were dominant in the completers' analysis and remained robust in the sensitivity analyses. In conclusion, acceptance and commitment therapy appears to be a cost-effective treatment compared with RPT in patients with FM.

PERSPECTIVE

Decision-makers have to prioritize their budget on the treatment option that is the most cost effective for the management of a specific patient group. From government as well as health care perspectives, this study shows that a GACT is more cost effective than pharmacological treatment in management of FM.

Differences in psychosocial responses to pain between sufficiently and insufficiently active adults with arthritis

OBJECTIVE

Adults with arthritis struggle to meet the physical activity recommendation for disease self-management. Identifying psychosocial factors that differentiate adults who meet (sufficiently active) or do not meet (insufficiently active) the recommendation is needed. This study sought to examine differences in psychosocial responses to arthritis pain among adults who were sufficiently or insufficiently active.

DESIGN

This prospective study included adults with medically diagnosed arthritis (N = 136, M_age = 49.75 ± 13.88 years) who completed two online surveys: (1) baseline: pain and psychosocial responses to pain and (2) two weeks later: physical activity.

MAIN OUTCOME MEASURES

Psychosocial responses examined in this study were psychological flexibility in response to pain, pain anxiety and maladaptive responses to pain anxiety.

RESULTS

A between-groups MANCOVA comparing sufficiently active (n = 87) to insufficiently active (n = 49) participants on psychosocial responses, after controlling for pain intensity, was significant (p = .005). Follow-up ANOVA's revealed that sufficiently active participants reported significantly higher psychological flexibility and used maladaptive responses less often compared to insufficiently active participants (p's < .05).

CONCLUSIONS

These findings provide preliminary insight into the psychosocial profile of adults at risk for nonadherence due to their responses to arthritis pain.
