Transformative Effects of Mindfulness Meditation Training on the Dynamic Reconfiguration of Executive and Default Mode Networks in Internet Gaming Disorder

Background

Internet gaming disorder (IGD) is a pervasive global mental health issue, and finding effective treatments for the disorder has been challenging. Mindfulness meditation (MM), recognized for its holistic approach that involves integrating mental and physical facets, holds promise for addressing the multifaceted nature of addiction. Nevertheless, the effect of MM on IGD and its associated neural networks, particularly in terms of their dynamic characteristics, remains elusive.

Methods

A total of 61 eligible participants with IGD (30 in the MM group, 31 in the progressive muscle relaxation [PMR] group) completed the experimental protocol, which involved pretest, an 8-session MM/PMR training regimen, and posttests. The 142 brain regions of interest were categorized into 5 brain networks using dynamic network reconfiguration analysis based on Shen's functional template. A comparative analysis of network dynamic features, including recruitment and integration coefficients, was performed across different groups and tests using resting-state functional magnetic resonance imaging data.

Results

While clinically nonspecific effects were observed in the PMR group, the MM group exhibited a significant reduction in addiction severity and cravings. In the dynamic brain network, MM training increased the recruitment coefficient within the frontoparietal network (FPN) and basal ganglia network (BGN) but decreased it within the default mode network (DMN). Furthermore, MM training increased the integration coefficient in the FPN-DMN and DMN-limbic network (LN).

Conclusions

MM has demonstrated pronounced efficacy in treating IGD. MM may enhance top-down control functions, cognitive and emotional functions, and reward-system processing, potentially through the reconfiguration of the FPN-DMN pathway, DMN-LN pathway, and BGN.

Research trends and hotspots of cognitive behavioral therapy for tinnitus: a bibliometric analysis

Background

Tinnitus, defined as the perception of sound without an external auditory stimulus, affects millions worldwide, significantly diminishing their quality of life. Cognitive behavioral therapy (CBT) is the most evidence-based treatment for tinnitus management, proven effective in reducing tinnitus-related distress and severity. This study aims to evaluate the current status, emerging trends, and research hotspots in CBT for tinnitus using bibliometric methods, offering valuable insights for future studies in this field.

Methods

Publications related to CBT for tinnitus were retrieved from the Web of Science Core Collection (WoSCC) database from 1985 to 2024. Bibliometric analysis and visualization were performed using VOSviewer, CiteSpace, and the R package "bibliometrix."

Results

A total of 209 publications were included in this study. Research on CBT for tinnitus has shown a steady upward trend. Sweden, the United Kingdom and the United States have made notable contributions to this field. Linköping University and Karolinska Institute are the leading research institutions. Gerhard Andersson is the most prolific author and ranks first in citation frequency. The most prolific journal is the American Journal of Audiology, while Ear and Hearing is the most frequently co-cited journal. The highly cited references primarily encompass clinical trials, systematic reviews, and meta-analyses that focus on cognitive-behavioral therapy interventions. Recent keyword trends highlight topics such as "mindfulness," "acceptance and commitment therapy," and "internet-based interventions." Addressing psychological comorbidities of tinnitus, including depression and anxiety, is identified as a future research focus.

Conclusion

This bibliometric analysis provides a comprehensive overview of the research landscape for CBT in tinnitus management. Current research emphasizes various CBT modalities to treat psychological comorbidities associated with tinnitus. Future studies should prioritize high-quality research to confirm the long-term efficacy of CBT in tinnitus management.

Exploring the application of acceptance and commitment therapy by occupational therapy practitioners: a scoping review protocol

OBJECTIVE

The proposed scoping review aims to explore the literature on the use of acceptance and commitment therapy (ACT) by occupational therapy (OT) practitioners, including how OT practitioners use ACT in the evaluation or intervention process, what types of client concerns they are addressing through ACT, in what settings they are using ACT, and what outcomes are being reported.

INTRODUCTION

ACT is a third-wave cognitive behavioral therapy that is effective across a wide range of diagnoses commonly seen by OT practitioners. Given the increased use of ACT by OT practitioners, a comprehensive understanding of its use in clinical practice would benefit OT practitioners, referring health care providers, and clients, as well as informing future research.

INCLUSION CRITERIA

The proposed review will consider studies that include participants of any age or diagnosis receiving OT services that involve ACT. All pertinent published studies will be considered, without limit on publication date or restriction on publication language. All primary studies, gray literature, text and opinion papers, and clinical guidelines will be considered.

METHODS

The proposed review will follow JBI methodology for scoping reviews. Searches will be conducted in PubMed, Embase (Ovid), Scopus, CINAHL (EBSCOhost), PsycINFO (EBSCOhost), OTSeeker, OTDBase, SciELO, ProQuest Dissertations and Theses Global, MedNar, and Google Scholar. All relevant sources will be screened by 2 reviewers independently, and data will be extracted using a standardized tool modified for the review. The results will be presented with frequency tables and narrative summaries.

Living successfully with chronic pain: Identifying the pivotal conditions needed to make it happen

Chronic pain is associated with many negative consequences for individuals and society. Given the burden it represents, many studies have focused on the risk factors involved, but very few have aimed to explain why some people live well with chronic pain, beyond the psychological realm. Thus, this study collected and analyzed different individual experiences to identify the pivotal conditions that help some individuals achieve quality of life despite chronic pain, with an emphasis on social considerations. We conducted a qualitative study using a narrative inquiry approach to unpack the participants' stories on these pivotal conditions. We carried out 25 individual interviews with persons who considered they had been living well with their pain for a minimum of 6 months. Data were analyzed using the inductive narrative method. Most participants were women (64%), White (88%), with a high level of education, and having low back or generalized pain (56%). Three main themes were identified: 1) a care partnership, 2) a nurturing environment, and 3) breaking free from previous life to move forward. These themes were then divided into 11 sub-themes, providing an in-depth understanding of the pivotal conditions needed to live well with chronic pain. The data collected suggest that to enable people to have a favorable evolution in the presence of chronic pain, a socio-ecological approach could be necessary to counteract painogenic environments. However, these results need to be validated and adapted to different populations. Perspective This study highlights the importance of a socio-ecological approach to living well with chronic pain, emphasizing that care partnerships, a nurturing environment and the ability to break with the past are essential to improve the quality of life of those affected.

Mindfulness interventions and quality of life in anxiety-related disorders: A systematic review and meta-analysis

Mindfulness-based interventions (MBIs) effectively treat anxiety symptoms across different anxiety and related disorders (ARDs), including panic disorder, social anxiety disorder, generalized anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder. In this systematic review and meta-analysis, we investigate whether MBIs also lead to improvements in the quality of life (QoL) of patients with ARDs. A systematic review was performed through electronic search in PUBMED, PsycINFO, Embase, Web of Science, and Clinical Trials databases. The inclusion criteria comprised randomized controlled trials (RCTs) investigating individuals diagnosed with ARDs who underwent MBIs with QoL as an outcome. The review included 15 RCTs, encompassing 1.465 participants. Broadly speaking, we found that MBIs were more effective than control groups in improving QoL for individuals with ARDs (Standardized Mean Difference, SDM = 0.175, 95 % CI 0.048 to 0.303). Upon classifying studies by control group types, MBIs demonstrated greater effectiveness than non-gold standard interventions (SDM = 0.213, 95 % CI 0.053 to 0.372). Notably, no significant difference was found between MBIs and gold standard interventions (SDM = 0.061, 95 % CI -0.175 to 0.297). MBIs may effectively improve QoL in individuals with ARDs. Further studies with larger samples are needed for more robust conclusions.

Assessing the efficacy of metacognitive therapy as monotherapy or adjunctive treatment in patient suffering from major depression and dysthimia: A comprehensive review of clinical trials

BACKGROUND

Depression is one of the most widespread diseases worldwide, with the highest rates of disability. Considering its chronic course, over the years several treatment options have been developed and validated, however still with high relapse rates. Therefore, in recent years, the so-called third wave psychotherapies have been developed for the treatment of psychiatric disorders. Among these, the Metacognitive therapy (MCT) has proven to be effective in treating depression. The aim of this review is to evaluate the efficacy of MCT as monotherapy or adjunctive treatment in reducing depressive symptoms in patients suffering from major depression or dysthymia.

METHODS

From bibliographic research in PubMed until December 2023, we retrieved 12 original studies meeting our research criteria.

RESULTS

The total sample of patients undergoing metacognitive therapy (MCT) included 376 individuals, while the control groups comprised 300 subjects, with a gender ratio of the participants of 0.48 %. The results show that metacognitive therapy is an effective approach in reducing depressive symptoms in patients with a diagnosis of depression or dysthymia when used as add-on therapy, with an efficacy comparable to CBT and superior to pharmacotherapy and as monotherapy, with an efficacy comparable to therapy with antidepressants compared to the control group and compared to cognitive-behavioral therapy with higher rates of reduction of depressive symptoms after treatment and at six months. Preliminary data also indicate its efficacy in terms of reduction of depressive symptoms in elderly people, suggesting its possible use in this population.

LIMITATIONS

The methodological heterogeneity in terms of treatment protocols of MCT and treatment control as well as the clinical heterogeneity of the sample employed may have limited the generalizability of the results.

CONCLUSIONS

The results suggest that the use of MCT, both as monotherapy and as an add-on treatment, is a valid therapeutic option for major depression, even at the later stages. However, further studies are needed for deeper our comprehension of the efficacy of MCT in depression.

"It's knowing that there are other people and they've accepted it": Patients' experiences of an acceptance and commitment therapy group intervention for people with neurological conditions

Individuals living with neurological conditions often face chronic issues including motor and sensory impairments and cognitive deficits. These challenges can lead to significant psychological difficulties, including anxiety, depression, and post-traumatic stress. Acceptance and Commitment Therapy (ACT) is a psychotherapeutic approach which aims to enhance psychological flexibility and acceptance while promoting behavioural change. Although ACT groups have shown promise in supporting individuals with neurological conditions, the evidence on patients' experiences of attending them is sparse. This project explored the experiences of individuals with a range of neurological conditions who had attended ACT group sessions as part of routine clinical practice, with the aim to refine future iterations of the intervention and enhancing patient care. Ten individual qualitative semi-structured interviews were carried out and the data were analysed thematically. Three overarching themes emerged from the analysis: (1) Initial Barriers to Group Attendance and Engagement; (2) Building an Environment of Acceptance; (3) Developing an ACT toolkit. Overall, the results showed that the ACT group intervention led participants to develop stronger emotional connectedness, better knowledge of their difficulties, more effective psychological skills, and different mindsets regarding their condition. Implications for the refinement of future ACT groups, neuropsychological service development, and clinical practice are discussed.

Move, connect and go outside! A randomized controlled trial of two online interventions and analysis of helpful coping strategies in COVID-19 "homestayers"

The COVID-19 pandemic has led to a global health crisis and a significant increase in psychological distress and psychopathological symptoms. We conducted a randomized controlled trial with two online interventions derived from positive psychology (PP) and acceptance and commitment therapy (ACT) in N = 138 "homestayers" during the first lock-down period in Germany. PP exercises had a positive impact on anxiety scores, which decreased significantly during the intervention, particularly in participants without access to a garden. Direct or indirect social contact, movement/exercise, and exposure to nature were the most frequently reported helpful coping strategies. We conclude that low-threshold online interventions with a focus on positive aspects of people's lives may be helpful to support mental health during pandemic crises. From a mental health perspective, the results also reinforce the approach of countries that allow their citizens to, for example, still go for walks during periods of contact restrictions, compared to full lock-down conditions.

Acceptance and commitment therapy with Huntington's disease: A narrative review and case report of a caregiver-assisted intervention

Acceptance and commitment therapy (ACT) is an experiential, action-oriented talk therapy that emphasizes acceptance of painful inner experience through increased psychological flexibility. In this narrative review and case report, we first review the extant literature on applications of ACT to patients with a variety of mental and physical health challenges, including neurodegenerative disorders, and their caregivers. We then discuss applications of ACT to Huntington's disease (HD). We provide a case report of a 52-year-old man living with HD who, accompanied by his caregiver, received a virtually-delivered 6-session ACT intervention. We measured the patient's self-reported symptoms of depression (PHQ-9) and anxiety (GAD-7) as well as his health-related quality of life (HDQoL) and level of cognitive fusion (i.e., being attached to his thoughts; CFQ-13) at baseline and following the intervention. At follow-up, the patient had a clinically significant reduction in depressive symptoms (from moderate to mild symptomatology) and cognitive fusion. Further, the patient had improvements in quality of life across the domains of physical functioning, mood, and worries. The promising outcomes of this case, as well as extant literature on the effectiveness of ACT in supporting individuals with similar neurodegenerative disorders, suggests that ACT may hold promise as a scalable and impactful intervention for individuals living with HD and their caregivers. We conclude with a call for further study of ACT with this population to build a more robust evidence base that can be used to benefit individuals living with HD and their caregivers.

Self-affirmation intervention for patients newly diagnosed with advanced cancer: a preliminary efficacy trial

OBJECTIVE

Cancer diagnosis represents a life crisis. It remains unclear whether/what psychosocial intervention may enhance cancer patients' quality of life (QoL) during existential plight. This study aimed to examine preliminary efficacy of a brief writing intervention for patients newly diagnosed with advanced cancer with a focus on affirming personally important values and beliefs.

METHODS

This is a single-arm pilot study testing effect of a 4-week home-based self-affirmation writing intervention for patients newly diagnosed with advanced cancer using interrupted time series design (NCT05235750). Patients were eligible if they were newly diagnosed (within 8 weeks) with advanced stage (III or IV) or recurrent cancer. Longitudinal analyses were performed using generalized linear mixed model incorporating the correlation of repeated measures. All statistical analyses were performed at 5% significance level using SAS® (version 9.4).

RESULTS

Fifty-seven patients newly diagnosed with advanced stage cancer with a mean age of 63 years balanced in gender were enrolled. Intent-to-treat analysis revealed significant post-intervention change for Faith as measured by the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being 12 item scale (FACIT-Sp-12) (ES 0.23, p = .05) and Ge6 "I worry that my condition will get worse" as measured by the Functional Assessment of Cancer Therapy - General (FACT-G) (ES 0.26, p = .10). When comparing changes pre- and post-intervention, Ge6 remained clinically significant (ESΔ 0.36, p = .27).

CONCLUSIONS

Self-affirmation via writing showed initial short-term efficacy in relieving cancer-specific existential concerns (Ge6 "I worry that my condition will get worse") and may be a promising innovative intervention approach that warrant randomized experiments to verify. Further research is also needed to find out who may most likely benefit from this intervention.

Efficacy of acceptance and commitment therapy on psychological rehabilitation in cancer patients treated with proton and heavy ion therapy: a non-randomized controlled trial

OBJECTIVE

To develop an appropriate intervention utilizing acceptance and commitment therapy (ACT) tailored specifically for cancer patients undergoing radiotherapy, and to investigate its impact on hope, psychological resilience, psychological flexibility, and psychological distress among cancer patients receiving proton and heavy ion therapy.

METHODS

Eighty participants were allocated into an intervention group (n = 40) or a control group (n = 40) based on their admission time. The control and intervention groups underwent a 3-week health education program, with the intervention group additionally participating in a 3-week, 6-session acceptance and commitment therapy (ACT) group psychological intervention. Discrepancies in hope levels, psychological resilience, psychological flexibility, and psychological distress between the two groups were assessed at baseline, post-intervention, and a 3-month follow-up using linear mixed-effects analysis (LMM).

RESULTS

LMM analyses revealed that at the end of the intervention, scores for hope and psychological resilience were higher in the intervention group compared to the control group (P = 0.025, P = 0.003), and scores for psychological flexibility were lower in the intervention group (P = 0.001). Furthermore, at the 3-month follow-up, HHI scores remained higher in the intervention group compared to the control group (P = 0.015). In contrast, scores for psychological flexibility and psychological distress were lower in the intervention group (P = 0.001, P = 0.001). These differences persisted even after adjusting for baseline values.

CONCLUSION

A psychological intervention program based on the ACT model of treatment helps to promote psychological recovery in cancer patients with radiotherapy. Evidence is provided for the effectiveness of positive clinical psychological interventions.

TRIAL REGISTRATION

The study was registered in the Chinese Clinical Trial Registry (ChiCTR2300068349) on 15th February, 2023.

Internet-based treatment for provoked vulvodynia: factors associated with treatment outcomes

INTRODUCTION

Previous research has indicated that internet-based Acceptance and Commitment Therapy (ACT) can reduce pain during intercourse and increase pain acceptance in individuals with provoked vulvodynia, but the factors associated with treatment outcomes remain unknown.

AIM

This study aimed to investigate factors associated with changes in pain acceptance following an internet treatment based on ACT.

METHODS

This exploratory study used data from the EMBLA study, a multicenter randomized controlled trial that investigated the effects of internet-based ACT for provoked vulvodynia. The examined factors included sociodemographics, medical history, pain and sexual behavior, and psychosocial characteristics. Linear regression analysis was employed to assess the association of these factors with pain acceptance, including interaction effects. Results were adjusted for multiple testing using Bonferroni correction.

OUTCOMES

The outcome measure was pain acceptance assessed on the scale Chronic Pain Questionnaire-Revised, which comprises two sub-scales: activity engagement and pain willingness.

RESULTS

Before adjustment, greater improvement in overall pain acceptance and the subscale activity engagement was seen participants in the intervention group who had a history of physical violence or sexual assault. Increased time spent on the treatment platform per week was also associated with greater improvement in pain acceptance. Participants who reported gastrointestinal problems before the internet-based treatment showed better treatment outcomes in activity engagement. Previous contact with a psychologist or counselor was associated with less improvement in activity engagement. The intervention was less effective on the subscale pain willingness with increased age and for those reporting urinary problems. No associations remained statistically significant after adjustment for multiple testing.

CLINICAL IMPLICATIONS

Previous exposure to violence and sexual assault, concomitant gastrointestinal or urinary problems, and adherence to treatment should be further investigated in larger studies on factors associated with treatment outcomes after internet treatment based on ACT, especially regarding pain.

STRENGTHS AND LIMITATIONS

This was a novel and exploratory study and provides information for researchers in future investigations of how individual characteristics may influence treatment outcomes. A range of variables were explored in the models, underscoring the importance of future studies to strengthen the findings. One limitation concerns the sample size, which was fairly small considering the nature of the study.

CONCLUSION

After correcting for multiple testing, no factors were found to be statistically associated with changes in pain acceptance after the treatment.

Combined Habit Reversal Therapy and Acceptance and Commitment Therapy for Treatment of Tics in Tourette Syndrome: A Pilot Study of Effectiveness and Response Duration

BACKGROUND

Few studies have examined the effectiveness and duration of mindfulness-based therapies for tics in Tourette's syndrome. This study combined habit reversal therapy (HRT) with acceptance and commitment therapy (ACT).

OBJECTIVES

To evaluate the efficacy and response duration of HRT + ACT in reducing tic severity in adults with Tourette's Syndrome.

METHODS

Tic severity was assessed at baseline, post-intervention, and at 6- and 12-month follow-ups using the Yale Global Tic Severity Scale (YGTSS) and video assessments. The intervention included eight weekly 1-h sessions.

RESULTS

Mixed-effects regression showed significant reductions in tic severity post-treatment (b = -10.36, P = 0.002), maintained at 6 months (b = -8.19, P = 0.012) and 12 months (b = -8.82, P = 0.009). Video assessments confirmed these findings.

CONCLUSION

The HRT + ACT protocol effectively reduced tic severity, with benefits lasting 12 months. These results support further trials to compare HRT + ACT with HRT alone.

The contextual interview: a cross-cutting patient-interviewing approach for social context

Patient interviewing pedagogy in medical education has not evolved to comprehensively capture the biopsychosocial model of healthcare delivery. While gathering a patient's social history targets important aspects of social context it does not adequately capture and account for the real-time reassessment required to understand evolving factors that influence exposure to drivers of health inequities, social determinants of health, and access to supports that promote health. The authors offer a patient interviewing approach called the Contextual Interview (CI) that specifically targets dynamic and ever-changing social context information. To substantiate the use of the CI in medical education, the authors conducted a qualitative review of the Accreditation Council for Graduate Medical Education Milestones for primary care specialties (Family Medicine, Internal Medicine, and Pediatrics). Milestones were coded to the extent to which they reflected the learner's need to acknowledge, assess, synthesize and/or apply patient contextual data in real-time patient encounters. Approximately 1 in 5 milestones met the context-related and patient-facing criteria. This milestone review further highlights the need for more intentional training in eliciting meaningful social context data during patient interviewing. The CI as a cross-cutting, practical, time-conscious, and semi-structured patient interviewing approach that deliberately elicits information to improve the clinician's sense and understanding of a patient's social context. The authors reviewed future directions in researching adapted versions of the CI for undergraduate and graduate medical education.

A Multiple Mediator Model of Depression, Dysfunctional Beliefs about Sleep, and Sleep Effort in the Relationship between Psychological Inflexibility and Insomnia in Shift Working Nurses

The aims of this study were to explore the influence of shift working nursing professionals' psychological inflexibility on their level of insomnia. Additionally, we investigated the mediation effect of depression and sleep-related cognitions on this association. An online survey was conducted among 202 nursing professionals at Asan Medical Center from July to August, 2023. Participants responded to questionnaires including the Insomnia Severity Index (ISI), Acceptance and Action Questionnaire-II (AAQ-II), Dysfunctional Beliefs and Attitudes about Sleep - 16 (DBAS-16), Glasgow Sleep Effort Scale (GSES), Patient Health Questionnaire-9 items (PHQ-9), and the Discrepancy between desired time in bed and desired total sleep time index (DBST index). Pearson's correlation and linear regression were performed to explore the factors predicting ISI scores. Mediation analysis was implemented. Linear regression revealed that insomnia severity was predicted by DBAS-16 (β = 0.15, p = 0.008), GSES (β = 0.48, p < 0.001), and PHQ-9 (β = 0.26, p < 0.001). Mediation analysis showed that the relationship between the psychological inflexibility of shift-working nursing professionals' and insomnia severity was fully mediated by depression, dysfunctional beliefs about sleep, and sleep effort. Psychological inflexibility does not directly influence insomnia severity, but depression, dysfunctional beliefs about sleep, and sleep effort fully mediate the relationship.

Chinese translation and validation of the Personalized Psychological Flexibility Index (PPFI) for medical college students

BACKGROUND

Psychological flexibility (PF) is defined as the ability to pursue valuable life goals despite the existence of distress. The Personalized Psychological Flexibility Index (PPFI) is a new measure of psychological flexibility that can address existing deficiencies. This study aimed to translate and validate the psychometric characteristics of the Chinese version of the PPFI among medical college students.

METHODS

The study was conducted in two phases. Phase 1 involved the translation and cross-cultural adaptation of the PPFI according to guidelines recommended by the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Phase 2 was a cross-sectional survey conducted on 945 medical college students in China. The psychometric performances of the scale were assessed using construct validity, divergent validity, criterion validity, incremental validity, internal consistency, and test-rest reliability.

RESULTS

The exploratory factor analysis (EFA, n1 = 440) showed that the Chinese version of the PPFI consisted of 3 factors, with a total of 15 items. The confirmatory factor analysis (CFA, n2 = 440) showed that the three-factor structure fit well (χ2/ df =2.469, SRMR = 0.051, RMSEA = 0.058, GFI = 0.94, CFI = 0.985). The total Chinese PPFI score had a moderate positive association with the Comprehensive Assessment of Acceptance and Commitment Therapy (CompACT, r = 0.344) and a negative association with the Acceptance and Action Questionnaire-II (AAQ-II, r = -0.334). Furthermore, the Chinese PPFI demonstrated good internal consistency (Cronbach's α = 0.826) and test-retest reliability (ICC = 0.817, p < 0.001).

CONCLUSION

The 15-item Chinese version of the PPFI is a reliable and valid tool for measuring PF in Chinese medical students. However, additional studies are needed to validate its psychometric properties in more generalizable samples and other contexts.

Digital cognitive-behavioral therapy for substance use: systematic review and meta-analysis of randomized controlled trials

Background: Prior meta-analyses have evaluated digital interventions for alcohol exclusively and alcohol/tobacco combined. These meta-analyses showed positive outcomes pertaining to alcohol and alcohol/tobacco combined. Yet questions remain pertaining to the effect of digital cognitive-behavioral therapy (CBT) on reducing alcohol and drug use.Objectives: The purpose of the meta-analysis was to determine the mean effect size, relative to control groups, of digital CBT, for posttest reductions in drug and/or alcohol use.Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria was used to guide this review and meta-analysis. Electronic databases (APA PsycArticles, Academic Search Complete, APA PsycInfo, CINAHL Complete, ERIC, MEDLINE, Psychology and Behavioral Sciences Collection, Social Sciences Full Text, Social Work Abstracts, SocINDEX), clinicaltrials.gov, reference lists were searched. The protocol was registered in PROSPERO (ID#: CRD42023471492). The CBT interventions included cognitive restructuring.Results: All but one of the effect sizes favored digital CBT (from -0.02 to -1.45). After the removal an outlier, a small, significant, random effects model Hedges' g summary effect of -0.23 (95% confidence interval: -0.32, -0.14, p < .0001) showed a reduction in substance use at the posttest, favoring digital CBT relative to the control group. A variety of control conditions were used; however, the effects sizes had minimal heterogeneity (k = 17, I2 = 5.34, Q = 16.9, p = .39). The funnel plot and Egger regression test intercept (0.01, p = .99) lacked publication bias.Conclusion: The meta-analytic findings suggest digital CBT is an efficacious treatment for reducing alcohol and drug use overall.

Concordance and Clinical Outcomes Improvement Following Oral Hygiene Motivation: A Systematic Review and Report of the Workshop of the Italian Societies of Dental Hygiene

Aim: A workshop on concordance and oral hygiene was held in February 2024. To address the topic, a systematic review aimed at investigating the effectiveness of motivational interventions in improving oral hygiene and focusing on periodontal clinical indices outcomes was designed. Materials and Methods: A comprehensive literature search was conducted across PubMed and Scopus electronic databases to identify relevant articles published up to 2024. Inclusion criteria encompassed studies comparing motivational interventions targeting oral hygiene behaviours, with a focus on periodontal clinical indices. Twelve articles meeting the eligibility criteria were selected for analysis. Quality assessment and data extraction were performed systematically. Results: The synthesis of findings from the selected studies revealed a consistent positive effect of motivational interventions on periodontal clinical indices. These interventions encompassed various strategies, including educational sessions, personalized feedback and motivational interviewing. Improvement in indices such as plaque index (PI), gingival index (GI) and periodontal probing depth was observed following motivational interventions, despite the variety of motivational protocols employed. Conclusion: Motivational interventions are effective in enhancing oral hygiene practices and improving periodontal clinical indices. Tailored motivational approaches can serve as valuable tools in promoting oral health behaviours among individuals, potentially reducing the risk of periodontal diseases. Further research is warranted to explore the long-term sustainability and scalability of motivational interventions in diverse populations and settings.

Proceedings of the 2022 "Lifestyle Intervention for Epilepsy (LIFE)" symposium hosted by Cleveland Clinic

Lifestyle interventions are strategies used to self-manage medical conditions, such as epilepsy, and often complement traditional pharmacologic and surgical therapies. The need for integrating evidence-based lifestyle interventions into mainstream medicine for the treatment of epilepsy is evident given that despite the availability of a multitude of treatments with medications and surgical techniques, a significant proportion of patients have refractory seizures, and even those who are seizure-free report significant adverse effects with current treatments. Although the evidence base for complementary medicine is less robust than it is for traditional forms of medicine, the evidence to date suggests that several forms of complementary medicine including yoga, mindfulness meditation, cognitive behavioral therapy, diet and nutrition, exercise and memory rehabilitation, and music therapy may have important roles as adjuncts in the treatment armamentarium for epilepsy. These topics were discussed by a diverse group of medical providers and scientists at the "Lifestyle Intervention for Epilepsy (LIFE)" symposium hosted by Cleveland Clinic. PLAIN LANGUAGE SUMMARY: There are many people with epilepsy who continue to have seizures even though they are being treated with medication or brain surgery. Even after seizures stop, some may experience medication side effects. There is research to suggest that certain lifestyle changes, such as yoga, mindfulness, exercise, music therapy, and adjustments to diet, could help people with epilepsy, when used along with routine treatment. Experts discussed the latest research at the "Lifestyle Intervention for Epilepsy (LIFE)" symposium hosted by Cleveland Clinic.

Testing the Effectiveness of a Mindfulness- and Acceptance-Based Smartphone App for Nurses Traumatized by the COVID-19 Pandemic: A Pilot Study

A significant proportion of frontline nurses developed post-traumatic stress disorder (PTSD) symptoms as a result of working during the COVID-19 pandemic. This study aimed to determine the efficacy of a mindfulness- and acceptance-based smartphone app intervention among nurses traumatized by the COVID-19 pandemic. This was a two-arm, randomized controlled trial. We randomly assigned 60 frontline nurses working in various clinical settings in the United States during the pandemic to either the intervention group (i.e. participants used the mindfulness app for 6 wk) or the wait-list control group. We assessed the app's efficacy through outcome measures of PTSD symptom severity, experiential avoidance, rumination, mindfulness, and resilience, measured at pre-, mid-, and post-intervention periods and a 1-month follow-up. Intervention satisfaction and perceived usability of the app were assessed within the intervention group. There was strong evidence of within-between interaction for PTSD, experiential avoidance, and rumination, implying significant improvement of these outcomes for the intervention group as compared to the control group. We only found a within-group interaction effect for mindfulness, indicating significant improvement of mindfulness within the intervention group only. Participants in the intervention group reported high satisfaction levels and perceived usability with the app. Findings highlight that mindfulness- and acceptance-based smartphone apps can improve PTSD symptoms of nurses traumatized by the pandemic. Healthcare organizations should provide nurses with accessible interventions (e.g. mindfulness apps) to treat and prevent secondary behavioral consequences of the pandemic, such as PTSD.

An online peer support program to improve mental health among university students: A randomized controlled trial

Despite recent calls for more peer support initiatives aimed at promoting mental health in postsecondary institutions, those initiatives remain scarce. In this study, a multisite randomized controlled trial was designed to assess the effect of an online peer support intervention based on acceptance and commitment therapy using mental health and school indicators. Undergraduate students were recruited in three Canadian universities and randomly assigned to an intervention (n = 54) or a wait-list control group (n = 53). Compared to control participants, those who took part in the program self-reported reduced psychological inflexibility, stress, anxiety and depression, and increased psychological flexibility and well-being. The intervention had no effect on academic satisfaction and engagement. These results were found both in completer and intent-to-treat samples. The findings provide evidence that peer support may be a beneficial adjunct to mental health interventions offered to college and university students.

Treatment of Psychological Symptoms in Patients with Cystic Fibrosis

The aim of this article is to identify and illustrate the most used psychological techniques in the field of cystic fibrosis (CF) and to help clinicians choose the most appropriate strategy among various possibilities. The disease and its medical treatments can be difficult to tolerate and can cause anxiety about health status or feelings of hopelessness and stress. The prevalence of depression and anxiety is 2.3 times higher in adults with CF than in community samples. A strong correlation has been identified between elevated psychological distress and unfavorable health outcomes, including, among others, impaired lung function, reduced BMI, an increased incidence of pulmonary exacerbations, and an elevated risk of transplantation. The use of psychological interventions is useful in addressing these common distresses in CF patients. Aware of the necessity of identifying efficacious interventions for all levels of depression and anxiety in CF patients, this study presents an overview of the research on psychological interventions for patients with CF, in order to complement the treatments suggested by the international guidelines on mental health in CF cases. In fact, the aim of this study is to conduct a review and quantitative synthesis of the psychological intervention techniques that are currently available for individuals with CF.

Diabetes Distress and Health-Related Quality of Life among Patients with Type 2 Diabetes-Mediating Role of Experiential Avoidance and Moderating Role of Post-Traumatic Growth

OBJECTIVES

Many people living with type 2 diabetes experience diabetes distress which impacts negatively on their health-related quality of life (HRQoL). However, little is known about the modifiable factors or psychological processes that make this happen. The current study examines the role of experiential avoidance and post-traumatic growth (PTG) in association with diabetes distress and the HRQoL.

METHODS

Participants included 303 patients with type 2 diabetes conveniently selected from two tertiary healthcare institutions in Nigeria. They completed relevant self-report measures. The Hayes PROCESS macro for SPSS was used for data analysis.

RESULTS

The results showed that experiential avoidance mediated the association between diabetes distress and the HRQoL [95% CI: -0.15, -0.07]. PTG significantly moderated the association between diabetes distress and the HRQoL [95% CI: 0.01, 0.02]. Specifically, diabetes distress was associated with a poor HRQoL only among patients with low levels of PTG but not among those with average and high levels of PTG.

CONCLUSION

These findings underscore the importance of Acceptance and Commitment Therapy as it can potentially decrease the experiential avoidance behaviour of patients. Moreover, intervention should also target the facilitation of PTG due to its beneficial effects in reducing the negative effects of diabetes distress on health and recovery.

The Effects of Mindfulness-Focused Internet-Based Cognitive Behavioral Therapy on Elevated Levels of Stress and Symptoms of Exhaustion Disorder: A Randomized Controlled Trial

Background

Internet-based Cognitive Behavior Therapy (ICBT) and mindfulness interventions are commonly used to treat elevated levels of stress. There are however few high-quality studies that examine ICBT with integrated mindfulness components for symptoms of stress and exhaustion, and the role of mindfulness exercises in digital treatment.

Method

The aim of the present study was to evaluate if a mindfulness-focused ICBT-program could reduce symptoms of stress and exhaustion, and increase quality of life, in a randomized controlled trial including 97 self-referred participants between 18 and 65 years who experienced elevated levels of stress.

Results

The intervention group had significantly reduced symptoms of stress and exhaustion, and increased quality of life, compared to the control group. Compared with the controls, participants in the intervention group showed a significant improvement with moderate to large effects on the primary outcome measure perceived stress (d = 0.79), and the secondary outcomes, exhaustion (d = 0.65), and quality of life (d = 0.40). Participants in the ICBT group also increased their level of mindfulness (d = 0.66) during the program. The amount of mindfulness training was significantly associated with an increased level of mindfulness, which in turn was significantly associated with reduced stress symptoms.

Conclusions

Mindfulness-focused ICBT can be an effective method to reduce stress-related mental health problems and the amount of mindfulness training seems to be of importance to increase the level of experienced mindfulness after treatment.

The 'Paths to everyday life' (PEER) trial - a qualitative study of mechanisms of change from the perspectives of individuals with mental health difficulties participating in peer support groups led by volunteer peers

BACKGROUND

Worldwide, peers support has been shown to play a crucial role in supporting people with mental illness in their personal recovery process and return to everyday life. Qualitiative studies underpinning the mechanisms of change in peer support has been reviewed. However, the findings are primeraly based on the perspectives of peer support workers employed in mental health services. Thus, qualitiative studies elucidating the mechanisms of change from the recipient perspective in mental health service independent civil society settings are higly needed to further contribute to the evidence of peer support. The 'Paths to every day life' (PEER) is evaluated in a randomized trial and is substantiated by qualitative studies investigating the experiences of PEER from the perspectives of the recipients and the facilitators of peer support. The purpose of this qualitative study underpinned by critical realism was to substantiate the PEER intervention program theory by gaining deeper insight into the change mechanisms and elaborate how, when, and under what circumstances the peer support groups potentially had or did not have an impact on personal recovery from the perspectives of the recipients of peer support.

METHODS

Eleven individuals were interviewed at the end of the ten-week group course. The semi-structured realist-inspired interviews were audio recorded and transcribed verbatim. The analysis was guided by reflective thematic analysis and through an abductive framework based on the program theory. Data were coded and analysed in Nvivo software.

RESULTS

Four overarching themes were identified that informed and nuanced the program theory: 1) Connectedness as a prerequisite for engagement; 2) A sense of hope by working out new paths to recovery; 3) Seeing new sides of oneself; and 4) Sprout for change.

CONCLUSIONS

This study substantiates the program theory and the quantitative results of the PEER trial by elaborating on mechanisms that were felt to be essential for the personal recovery process from the perspectives of the recipients of the group-based peer support. In addition, the study points out that the opportunities to act in everyday life depended on individual context and where the group participants were on their recovery journey.

Living well with chronic pain: a 12-month randomized controlled trial revealing impact from the digital pain self-management program EPIO

Introduction

Chronic pain affects a wide range of physical and psychological aspects of life for those impacted. Psychosocial treatment approaches may be of support, but outreach is still limited.

Objectives

To evaluate the efficacy of EPIO, an evidence-informed, user-centered digital self-management intervention for people with chronic pain, in a 12-month randomized controlled trial.

Methods

People living with chronic pain (N = 266) were randomized to the EPIO intervention (n = 132) or a usual-care control group (n = 134). The intervention was delivered in a simple blended care model, and outcome measures collected at baseline, 6 months, and 12 months. Generalized linear models for repeated measures were fitted to compare groups over time.

Results

Participants were primarily female (81%), median age 49 years (range 22-78), with heterogeneous pain conditions, and had lived with pain >5 years (77.6%). A mixed linear model with all timepoints included revealed no statistically significant group differences for the primary outcome of pain interference. Significant psychological benefits in favor of the intervention group were however detected for depression (P = 0.022), self-regulatory fatigue (P = 0.024), vitality (P = 0.016), and mental health (P = 0.047). Baseline to 12-month changes showed additional favorable effects for anxiety (between-group mean differences [MDs] = 0.79, P = 0.047), depression (MD = 1.08, P = 0.004), self-regulatory fatigue (MD = 2.42, P = 0.021), pain catastrophizing (MD = 2.62, P = 0.009), and health-related quality of life.

Conclusions

The EPIO program aims to improve outreach of evidence-based pain self-management interventions. Findings demonstrate how using EPIO can lead to sustainable psychological change, enhancing mental health and health-related quality of life for people suffering from pain, providing a chance to live well with the pain.

Wellbeing After Stroke (WAterS): Feasibility Testing of a Co-developed Acceptance and Commitment Therapy Intervention to Support Psychological Adjustment After Stroke

OBJECTIVE

Feasibility test a co-developed intervention based on Acceptance and Commitment Therapy to support psychological adjustment post-stroke, delivered by a workforce with community in-reach.

DESIGN

Observational feasibility study utilising patient, carer, public involvement.

SETTING

Online. UK.

PARTICIPANTS

Stroke survivors with self-reported psychological distress 4  +  months post-stroke.

INTERVENTIONS

The co-developed Wellbeing After Stroke (WAterS) intervention includes: 9-weekly, structured, online, group sessions for stroke survivors, delivered via a training programme to upskill staff without Acceptance and Commitment Therapy experience, under Clinical Psychology supervision.

MAIN MEASURES

Feasibility of recruitment and retention; data quality from candidate measures; safety. Clinical and demographic information at baseline; patient-reported outcome measures (PROMs) via online surveys (baseline, pre- and post-intervention, 3 and 6 months after intervention end) including Mood (hospital anxiety and depression scale (HADS)), Wellbeing (ONS4), Health-Related Quality of Life (EQ5D5L), Psychological Flexibility (AAQ-ABI) and Values-Based Living (VQ).

RESULTS

We trained eight staff and recruited 17 stroke survivors with mild-to-moderate cognitive and communication difficulties. 12/17 (71%) joined three intervention groups with 98% attendance and no related adverse events. PROMS data were well-completed. The HADS is a possible future primary outcome (self-reported depression lower on average by 1.3 points: 8.5 pre-group to 7.1 at 3-month follow-up; 95% CI 0.4 to 3.2).

CONCLUSION

The WAterS intervention warrants further research evaluation. Staff can be trained and upskilled to deliver. It appears safe and feasible to deliver online to groups, and study recruitment and data collection are feasible. Funding has been secured to further develop the intervention, considering implementation and health equality.

The relationship between fear of cancer recurrence and death anxiety among Chinese cancer patients: the serial mediation model

AIMS

This study aims to investigate the association between fear of cancer recurrence (FCR) and death anxiety (DA) among Chinese cancer patients, while considering the mediating effects of experiential avoidance (EA) and meaning in life (MIL).

METHODS

From February to June 2023, convenience sampling was used to select newly diagnosed cancer patients in a tertiary Cancer Hospital in Chinese Hunan Province as the survey objects. A total of 436 cancer patients completed the Fear of Cancer Recurrence Inventory, the Meaning in Life Questionnaire, the Acceptance and Action Questionnaire-II, and the Templer's death anxiety scale. Descriptive analysis and Pearson correlation analysis were conducted using SPSS 28.0 software. Serial mediation analysis was performed by Hayes' PROCESS macro.

RESULTS

Gender, age, educational level, marital status, residence, occupation, per capita monthly household income, tumor type, and cancer stage were controlled in the model. The results revealed that fear of cancer recurrence had a significant direct effect on death anxiety (Effect = 0.075, 95% CI: 0.064 to 0.087). Additionally, three indirect pathways were identified: (1) through experiential avoidance (Effect = 0.037, 95% CI: 0.026 to 0.049), (2) through meaning in life (Effect = 0.022, 95% CI: 0.014 to 0.031), and (3) through the serial mediators involving meaning in life and experiential avoidance (Effect = 0.016, 95% CI: 0.010 to 0.023). The total indirect effect of the three mediation paths was 63.56%.

CONCLUSION

Fear of cancer recurrence is a significant psychological distress experienced by cancer patients, which not only directly contributes to death anxiety but also may triggers changes, such as experiential avoidance and meaning in life. Ultimately, this comprehensive psychological distress leads to death anxiety.

Effectiveness of a mindfulness and acceptance-based intervention for improving the mental health of adolescents with HIV in Uganda: An open-label trial

Adolescents with HIV (AWH) face the double burden of dealing with challenges presented by their developmental phase while coping with stigma related to HIV, affecting their mental health. Poor mental health complicates adherence to daily treatment regimens, requiring innovative psychosocial support strategies for use with adolescents. We assessed the effectiveness of a mindfulness and acceptance-based intervention on the mental health of AWH in Uganda. One hundred and twenty-two AWH, mean age 17 ±1.59 (range 15 to 19 years), 57% female, receiving care at a public health facility in Kampala were enrolled in an open-label randomized trial (ClinicalTrials.gov: NCT05010317) with assessments at pre-and post-intervention. The mindfulness and acceptance-based intervention involved weekly 90-minute group sessions for four consecutive weeks facilitated by two experienced trainers. Sessions involved clarifying values, skillfully relating to thoughts, allowing and becoming aware of experiences non-judgmentally, and exploring life through trial and error. The control group received the current standard of care. Three mental health domains (depression, anxiety, and internalized stigma) were compared between the intervention and control groups. A linear mixed effects regression was used to analyze the effect of the intervention across the two time points. Results showed that the intervention was associated with a statistically significant reduction in symptoms of depression (β = -10.72, 95%CI: 6.25, -15.20; p < .0001), anxiety (β = -7.55, 95%CI: 2.66, -12.43; p = .0003) and stigma (β = -1.40, 95%CI: 0.66 to -2.15; p = .0004) over time. Results suggest that mindfulness and acceptance-based interventions have the potential to improve the mental health of AWH.

EEG changes induced by meditative practices: State and trait effects in healthy subjects and in patients with epilepsy

The effect of meditation on brain activity has been the topic of many studies in healthy subjects and in patients suffering from chronic diseases. These effects are either explored during meditation practice (state effects) or as a longer-term result of meditation training during the resting-state (trait). The topic of this article is to first review these findings by focusing on electroencephalography (EEG) changes in healthy subjects with or without experience in meditation. Modifications in EEG baseline rhythms, functional connectivity and advanced nonlinear parameters are discussed in regard to feasibility in clinical applications. Secondly, we provide a state-of-the-art of studies that proposed meditative practices as a complementary therapy in patients with epilepsy, in whom anxiety and depressive symptoms are prevalent. In these studies, the effects of standardized meditation programs including elements of traditional meditation practices such as mindfulness, loving-kindness and compassion are explored both at the level of psychological functioning and on the occurrence of seizures. Lastly, preliminary results are given regarding our ongoing study, the aim of which is to quantify the effects of a mindfulness self-compassion (MSC) practice on interictal and ictal epileptic activity. Feasibility, difficulties, and prospects of this study are discussed.

Psychometric evidence of the Acceptance and Action Questionnaire-II (AAQ-II): an item response theory analysis in university students from Chile

BACKGROUND

Experiential avoidance (EA) is a psychological mechanism associated with several mental health disorders and is regarded as a relevant target by third-generation cognitive behavioral therapies. It has been mainly assessed through self-report questionnaires, and the AAQ-II is the most used tool. Its psychometric evidence has been mostly tested through the classical test theory (CTT) and very scarcely assessed through Item Response Theory (IRT).

METHODS

We used the Graded Response Model to examine its psychometric properties in Spanish-speaking university students (n = 1503; women = 995 (66.2%), mean age = 19.29, SD = 2.45). We tested whether the empirical data fit the model's predictions and estimated the dispersion of persons and items along the experiential avoidance continuum. Moreover, we examined category probability curves to identify the response probability of each answer. Likewise, an item-person map was made where the measurement of persons and items, both on the same scale and along the experiential avoidance continuum, could be observed jointly. Finally, we tested the gender invariance of the scale.

RESULTS

We found that the values of the individuals and the items were in the established range to be considered an adequate measure of EA. Additionally, we observed high discrimination indices for all items. The current version with seven answer options could not be optimal and should be tested in future studies. Finally, we found evidence of differential functioning by gender in one of the seven items of the instrument.

CONCLUSIONS

Our results indicate that the AAQ-II is a suitable tool for measuring EA and accurately classifying and differentiating EA levels in university students.

Psychotherapies for Generalized Anxiety Disorder in Adults: A Systematic Review and Network Meta-Analysis of Randomized Clinical Trials

Importance

Generalized anxiety disorder (GAD) is one of the most common mental disorders in adults. Psychotherapies are among the most recommended treatments for GAD, but which should be considered as first-line treatment needs to be clarified.

Objective

To use a network meta-analysis to examine the short- and long-term associations of different psychotherapies with outcomes of effectiveness and acceptability in adults with GAD.

Data Sources

MEDLINE, Embase, PsycINFO, and the Cochrane Register of Controlled Trials were searched from database inception to January 1, 2023, to identify randomized clinical trials (RCTs) of psychotherapies for adults with GAD.

Study Selection

RCTs comparing any type of psychotherapy against another or with a control condition for the treatment of adults (≥18 years, both sexes) with a primary diagnosis of GAD were eligible for inclusion.

Data Extraction and Synthesis

This study followed Cochrane standards for extracting data and assessing data quality and used the PRISMA guideline for reporting. Risk of bias of individual studies was assessed using the second version of the Cochrane risk of bias tool, and the Confidence in Network Meta-Analysis was used to rate the certainty of evidence for meta-analytical results.

Main Outcomes and Measures

Eight psychotherapies were compared against one another and with 2 control conditions. Primary outcomes were severity of GAD symptoms and acceptability of the psychotherapies. Random-effects model pairwise and network meta-analyses were conducted. For effectiveness, standardized mean differences (SMDs) were pooled, and for acceptability, relative risks with 95% CIs were calculated.

Results

Data from 65 RCTs were included. Effect size estimates on data from 5048 participants (mean [SD], 70.9% [11.9%] women; mean [SD] age, 42.2 [12.5] years) suggested that third-wave cognitive behavior therapies (CBTs) (SMD, -0.76 [95% CI, -1.15 to -0.36]; certainty, moderate), CBT (SMD, -0.74 [95% CI, -1.09 to -0.38]; certainty, moderate), and relaxation therapy (SMD, -0.59 [95% CI, -1.07 to -0.11]; certainty, low) were associated with reduced GAD symptoms vs treatment as usual. Relative risks for all-cause discontinuation (indication of acceptability) signaled no differences compared with treatment as usual for all psychotherapies (eg, relative risk, 1.04 [95% CI, 0.64-1.67] for CBT vs treatment as usual). When excluding studies at high risk of bias, relaxation therapy lost its superiority over treatment as usual (SMD, -0.47; 95% CI, -1.18 to 0.23). When considering anxiety severity at 3 to 12 months after completion of the intervention, only CBT remained significantly associated with greater effectiveness than treatment as usual (SMD, -0.60; 95% CI, -0.99 to -0.21).

Conclusions and Relevance

Given the evidence in this systematic review and network meta-analysis for its associations with both acute and long-term effectiveness, CBT may represent the first-line therapy of GAD. Third-wave CBTs and relaxation therapy were associated with short-term effectiveness and may also be offered.

How COVID-19 prevention burnout impacts emotional symptoms among Chinese college students: A moderated mediation model

The current study investigated the relationship between COVID-19 prevention burnout and emotional symptoms (depression and anxiety) among 1,837 Chinese college students and the underlying mechanisms. Results from moderated mediation analysis revealed that the association between COVID-19 prevention burnout and emotional symptoms was mediated by psychological inflexibility (β = 0.20, 95%CI = [0.10, 0.19]). Also, COVID-19 prevention burnout's direct and indirect effects on emotional symptoms were more substantial for students with high susceptibility to emotional contagion than those with low susceptibility. These findings contribute to understanding how COVID-19 prevention burnout relates to emotional symptoms and provide a new perspective for interventions promoting students' psychological flexibility, particularly those with higher susceptibility to emotional contagion.

The Effect of Psychological Inflexibility on Social-Distancing Phobia Mediated by Preoccupation With Sleep and Intolerance of Uncertainty in the Elderly Population During the COVID-19 Pandemic

OBJECTIVE

The aim of this study was to explore whether psychological inflexibility in the elderly population is related to social-distancing phobia, and examine whether their viral anxiety, preoccupation with sleep, or intolerance of uncertainty may mediate the relationship.

METHODS

Among the elderly population aged ≥65 in Korea, we conducted an anonymous online survey during January and February 2023. We collected the responses of 300 participants, collected demographic information, and symptoms using rating scales such as the Social-Distancing Phobia scale, Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), Intolerance of Uncertainty Scale-12 (IUS-12), Acceptance and Action Questionnaire-II (AAQ-II), and Glasgow Sleep Effort Scale (GSES).

RESULTS

Social-distancing phobia was expected by the SAVE-6 (β=0.34, p<0.001), IUS-12 (β=0.18, p=0.003), and GSES (β=0.18, p= 0.001) in the linear regression analysis. In the mediation analysis, psychological inflexibility did not directly influence social-distancing phobia. However, viral anxiety, intolerance of uncertainty, or preoccupation with sleep completely mediated the influence of psychological inflexibility on social-distancing phobia among elderly population.

CONCLUSION

The management of psychological inflexibility, intolerance of uncertainty, or preoccupation with sleep needs to be considered when designing interventions to address social-distancing phobia in elderly populations in future pandemics.

Acceptance and commitment therapy reduces psychological distress in patients with cancer: a systematic review and meta-analysis of randomized controlled trials

Objective

This study aimed to systematically review and meta-analyze the clinical efficacy of acceptance and commitment therapy (ACT) in patients with cancer and psychological distress.

Methods

Randomized controlled trials (RCTs) from seven English electronic databases were systematically investigated from inception to 3 October 2023. A total of 16 RCTs from 6 countries with 711 participants were included in this study. Estimated pooled effect sizes (ESs) were calculated via inverse-variance random-effects or fixed-effects (I2 ≤ 50%) model and presented by standardized mean difference (SMD). Subgroup analyses were performed to reduce confounding factors and heterogeneity, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to evaluate the quality of the pooled ESs.

Results

The pooled ESs revealed that statistically significant improvements in anxiety [postintervention SMD = -0.41 (95% confidence interval (CI), -0.71, -0.11); p = 0.008; I2 = 65%; follow-up SMD = -0.37 (95% CI, -0.66, -0.08); p = 0.01; I2 = 29%], depression [postintervention SMD = -0.45 (95% CI, -0.63, -0.27); p < 0.001; I2 = 49%; follow-up SMD = -0.52 (95% CI, -0.77, -0.28); p < 0.001; I2 = 0%], and psychological flexibility [postintervention SMD = -0.81 (95% CI, -1.50, -0.11); p = 0.02; I2 = 84%; follow-up SMD = -0.71 (95% CI, -1.12, -0.31); p = 0.0006; I2 = 38%] in ACT-treated participants were observed compared to patients treated with control conditions. However, other outcomes, such as physical symptom alleviation, were not significantly associated.

Conclusion

The findings of this systematic review and meta-analysis suggest that ACT is associated with improvements in anxiety, depression, and psychological flexibility in patients with cancer.

Cognitive-behavioral and mindfulness-based interventions for distress in patients with advanced cancer: A meta-analysis

OBJECTIVE

Various psychosocial interventions have been developed to reduce distress and improve quality of life (QoL) in patients with advanced cancer, many of which are traditional cognitive-behavioral interventions (CBIs) or mindfulness-based interventions (MBIs). The aims of this meta-analysis were to determine and compare the overall effects of traditional CBIs and MBIs on distress and QoL in this population and to explore potential moderators of intervention efficacy.

METHODS

A systematic search was conducted in CINAHL, Embase, PsycINFO, PubMed, and Web of Science. Randomized controlled trials (RCTs) comparing CBIs or MBIs to controls on distress and QoL outcomes were eligible for inclusion. Random effects meta-analyses using standardized baseline to post-intervention mean differences were calculated using Hedges's g. Meta-regressions were used to compare intervention effects and examine potential moderators.

RESULTS

Across 37 RCTs (21 CBIs, 14 MBIs, 2 combination therapies), there was a small decrease in distress (Hedges's g = 0.21) and a minimal improvement in QoL (Hedges's g = 0.15). Traditional CBIs and MBIs did not differ in effect sizes. Heterogeneity was significant across distress effect sizes but not across QoL effects. Interventions delivered to individuals (vs. dyads/group) had larger effects on QoL. No moderators of intervention effects on distress were found.

CONCLUSIONS

Findings suggest traditional CBIs and MBIs produce small reductions in distress compared to controls in patients with advanced cancer, although effects on QoL appear minimal. Given limitations in the number of studies and their quality, rigorous trials are needed to directly compare the impact of traditional CBIs and MBIs in this population.

Acceptance and Commitment Therapy for Major Depressive Disorder: Navigating Depression Treatment in Traditional and Digital Settings with Insights from Current Research

Given the shortcomings of a mechanistic assumption of traditional cognitive behavioral therapy (CBT), a newer generation of CBT-grounded interventions focusing on process-orientated emotional and motivational aspects has emerged. These so-called third-wave CBTs emphasize function and context of inner experience over form and content, and have become evidence-based practice in the past four decades. Among these approaches, acceptance and commitment therapy (ACT) has both a large body of research for various (mental) health conditions, including major depressive disorder (MDD) in particular. ACT is a transdiagnostic approach that intends to increase psychological flexibility (PF) of clients as a universal mechanism of behavior change and a value-driven orientation in life. By focusing on present-moment awareness, acceptance, defusion, establishing a stable sense of self, clarifying personal valued life directions, and committing to behaviors consistent to these values, ACT targets the core processes of PF. Meta-analyses have indicated the efficacy and effectiveness of ACT in reducing depressive symptoms and increasing well-being, with mainly moderate effect sizes in clinical trials. ACT for MDD has been shown to be effective across different delivery modes (e.g., individual, group, digital). ACT can also be applied using self-help formats (e.g., mobile apps) and combined with features from compatible approaches like behavioral activation. There is also evidence for a high acceptability of ACT and adherence rates comparable to classic CBT. Moreover, process research has shown that ACT works specifically through the mediator of PF and by addressing its suggested core therapeutic processes. Given the essential role of offering a personalized therapeutic strategy in treatment outcomes and adherence, it is central to provide more effective options that match clients' needs and preferences. This chapter illustrates different applications of ACT for adults with MDD and the current evidence base to promote informed decisions on using ACT as additional or stand-alone therapeutic approach.

Cognitive Behavioral Therapy and Mindfulness-Based Cognitive Therapy for Depressive Disorders: Enhancing Access and Tailoring Interventions in Diverse Settings

Depressive disorders are an enormous societal burden given their high prevalence and impact on all facets of being human (e.g., relationships, emotions, motivation). There is a variety of evidence-based psychological treatments, with cognitive behavioral therapy (CBT) being the gold standard for major depression. Research has shown that mindfulness-based interventions (MBIs) such as mindfulness-based cognitive therapy (MBCT) are an effective relapse prevention and treatment for depression and that MBIs can be integrated in individual therapy. Furthermore, various delivery modes (e.g., digital-delivered therapy) and settings are offered to best meet different needs and improve accessibility: Evidence suggests that therapist-guided digital CBT, blended therapy, and, to some degree, digitalized MBIs may be an efficacious supplement to traditional face-to-face therapy. This chapter provides an overview of the principles and evidence base for CBT and MBCT as well as different delivery modes for depressive disorders in adults. Finally, chances and challenges of integration are discussed as implications for practice, as well as recommendations and ideas for future research.

A Neurobiological-Behavioral Approach to Predicting and Influencing Private Events

The primary goals of behavior analysis are the prediction and influence of behavior. These goals are largely achieved through the identification of functional relations between behaviors and the stimulating environment. Behavior-behavior relations are insufficient to meet these goals. Although this environment-behavior approach has been highly successful when applied to public behaviors, extensions to private events have been limited. This article discusses technical and conceptual challenges to the study of private events. We introduce a neurobiological-behavioral approach which seeks to understand private behavior as environmentally controlled in part by private neurobiological stimuli. These stimuli may enter into functional relations with both public and private behaviors. The analysis builds upon several current approaches to private events, delineates private behaviors and private stimulation, and emphasizes the reciprocal interaction between the two. By doing so, this approach can improve treatment and assessment of behavior and advance understanding of concepts such as motivating operations. We then describe the array of stimulus functions that neurobiological stimuli may acquire, including eliciting, discriminative, motivating, reinforcing, and punishing effects, and describe how the overall approach expands the concept of contextual influence. Finally, we describe how advances in behavioral neuroscience that enable the measurement and analysis of private behaviors and stimuli are allowing these once private events to affect the public world. Applications in the area of human-computer interfaces are discussed.

Effects and Mechanisms of a Web- and Mobile-Based Acceptance and Commitment Therapy Intervention for Anxiety and Depression Symptoms in Nurses: Fully Decentralized Randomized Controlled Trial

BACKGROUND

Acceptance and commitment therapy (ACT) is a promising intervention for improving mental health. However, there is limited evidence on its effectiveness for nurses, particularly in web- and mobile-based intervention forms, in mitigating anxiety and depression symptoms.

OBJECTIVE

In this study, we aimed to examine the effect and underlying psychological mechanisms of a web- and mobile-based ACT intervention on nurses' anxiety and depression symptoms.

METHODS

In this fully decentralized randomized controlled trial, nurses were recruited nationwide across China through advertisements and posters. They were randomly assigned to either the 5-week fully automated intervention or the waiting group. Primary outcomes (anxiety and depression symptoms); secondary outcomes (sleep quality, burnout, and work performance); and mediators (psychological flexibility, cognitive defusion, mindfulness, and values) were assessed using the Wenjuanxing platform. Data collectors were blinded to the group assignments throughout the study period.

RESULTS

A total of 145 nurses with anxiety or depression symptoms were randomly assigned to either the intervention group (n=72, 49.7%) or the control group (n=73, 50.3%); 97.2% (n=141) were female. During the study, 36 (24.8%) nurses were lost to follow-up, and 53 (73.6%) completed the entire intervention. Nurses in the intervention group showed significant improvement in anxiety (d=0.67, 95% CI 0.33-1.00) and depression symptoms (d=0.58, 95% CI 0.25-0.91), and the effects were sustained for 3 months after the intervention (anxiety: d=0.55, 95% CI 0.22-0.89; depression: d=0.66, 95% CI 0.33-1.00). Changes in psychological flexibility, cognitive defusion, and values mediated the effect of the intervention on anxiety and depression symptoms, while mindfulness did not have a mediating effect.

CONCLUSIONS

The web- and mobile-based ACT intervention used in this study significantly improved nurses' anxiety and depression symptoms by improving psychological flexibility, cognitive defusion, and values. The results provide new ideas for hospital administrators to prevent and intervene in nurses' psychological issues.

Effectiveness of Internet-delivered self-help acceptance and commitment therapy (iACT) on nurses' obsessive-compulsive symptoms and sleep quality: A randomized controlled trial with 3-month follow-up

BACKGROUND

Frontline nurses suffered unprecedented mental distress during the COVID-19 pandemic. It's essential to explore new and more accessible alternatives to improve the availability of psychological treatments. This study aimed to investigate the influence of online self-help iACT linear intervention and iACT loop intervention on sleep quality (SQ), obsessive-compulsive symptoms (OCS), and psychological flexibility (PF) in nurses.

METHODS

A randomized controlled trial was conducted at a hospital in China. 602 participants were randomly assigned to the iACT linear intervention, iACT loop intervention, or wait list control group, and required to complete the questionnaires of OCS, PF and SQ. The linear mixed effects analysis (LMM) was used to analyze the impact of the intervention on outcome variables.

RESULTS

LMM analyses demonstrated that both two intervention had significant improvement on OCS (t = -38.235, p < 0.001), PF (t = 28.156, p < 0.001), as well as SQ (t = -16.336, p < 0.001). There were significant differences between the linear group and loop group on the PF in T2 (t = -8.271, p < 0.001), T3 (t = -8.366, p < 0.001), T4 (t = -8.302, p < 0.001), with the iACT loop model (Cohen's d = 1.652) showing a slight advantage over the iACT linear model (Cohen's d = 1.134).

CONCLUSIONS

The findings indicate that two interventions positively impact OCS, PF, and SQ. Compared to the iACT linear psychotherapy model, the iACT loop model shows greater effectiveness in enhancing PF, making it helpful to promote significant improvements in psychotherapy planning.

The rapid stabilization pathway: impact of a brief inpatient intervention on the length of stay and readmissions among psychiatrically hospitalized adolescents

BACKGROUND

Suicide is the second leading cause of death among adolescents in the United States (Centers for Disease Control and Prevention [CDC], 2017, Death rates due to suicide and homicide among persons age 10-24: United States, 2000-2017) constituting a significant public health crisis. The demand for psychiatric emergency services and inpatient beds is increasing, while the number of beds available decreases or remains static (National Association of State Mental Health Program Directors, 2017, Trend in psychiatric inpatient capacity, United States and Each State, 1970-2014. www.nasmhpd.org/sites/default/files/TACPaper.2.Psychiatric-Inpatient-Capacity_508C.pdf) leading to delays in treatment and exacerbation of symptoms for some adolescents awaiting care. This pilot project describes the development, feasibility, and acceptability of a creative, values-based safety planning intervention for adolescents hospitalized on an acute inpatient psychiatric unit and the impact of this intervention on length of stay and readmissions to acute psychiatric care.

METHODS

Thirty patients experiencing a suicidal crisis participated in the Rapid Stabilization Pathway (RSP) during their inpatient psychiatric admission.

RESULTS

Results indicate that, compared to patients who underwent inpatient treatment as usual (TAU), RSP patients were discharged after a significantly shorter length of stay (4 vs. 6.1 weekdays respectively, p < .001). Further, there was no significant difference in readmission to the inpatient unit or to the psychiatric emergency room among RSP and TAU patients at 30, 60, and 90 days postdischarge.

CONCLUSIONS

These findings have significant implications for acute inpatient programming. The RSP intervention treated patients in a shorter amount of time without any increase in re-admissions. Further, the shortened length of stay allowed for more patients to be treated on the inpatient unit and a significant cost savings. Future directions for programming and outcome research are discussed.

The Mediating Effect of Experiential Avoidance on the Relationship between Diabetes Distress and Self-Stigma in People with Diabetes Mellitus Type 2 in Republic of Korea

This descriptive study aimed to explore the mediating role of experiential avoidance in the association between diabetes distress and self-stigma in Korean patients with diabetes mellitus type 2. The study included 196 participants with diabetes mellitus type 2, diagnosed by an endocrinologist. Data were collected from 20 September to 31 September 2021, using an online self-report questionnaire focusing on diabetes distress, diabetes self-stigma, and experiential avoidance. For the mediating effect analysis, a three-step hierarchical multiple analysis was performed using SPSS, and the mediating effect was verified using SPSS PROCESS Macro. The findings revealed that the average scores for diabetes distress, self-stigma, and experiential avoidance were 3.01 ± 0.66, 2.57 ± 0.82, and 3.65 ± 0.55, respectively. Positive correlations were observed among diabetes distress, self-stigma, and experiential avoidance. Specifically, experiential avoidance partially mediated the relationship between diabetes distress and self-stigma, accounting for 47.7% of the variance. These findings reveal that it is crucial to focus on countering experiential avoidance to assist patients with diabetes mellitus type 2 in overcoming the self-stigma and distress related to their condition. In addition, it is necessary to develop a gradual and tailored program aimed at reducing experiential avoidance.

Third-wave cognitive behavioral therapies for caregivers of cancer patients: a scoping review

BACKGROUND

Cancer caregivers extend comprehensive support covering all aspects of patients' daily lives. It has been reported that a significant proportion of cancer caregivers experience emotional distress. As one way to solve this problem, third-wave cognitive behavioral therapies (CBT), which involves integrating acceptance and mindfulness into cognitive‒behavioral therapy, has been applied to improve caregiver outcomes.

METHODS

A scoping review was conducted based on the scoping review guidelines proposed by the Jonna Briggs Institute (JBI). The population was caregivers of cancer patients, the concept was third-wave CBT, and the context remained open. English and Korean publications published from 2001 to June 2022 were identified from PubMed, Embase, CINAHL, PsycINFO, Cochrane, Korea Med, and RISS.

RESULTS

A total of 12 studies were included in this scoping review. Mindfulness-Based Stress Reduction (MBSR) and Acceptance and Commitment Therapy (ACT) was the most frequently applied intervention (n = 3, each). Among the components of third-wave CBT, 'mindfulness' was identified in all the studies reviewed (n = 12). Dyadic interventions comprised the majority (n = 9). Interventions using digital technologies such as mobile application/web page (n = 3), telephone (n = 3), and FaceTime (n = 2) have increased since 2017. Depression was the most frequently evaluated outcome (n = 8), followed by anxiety and mindfulness (n = 6, each).

CONCLUSIONS

The current review explored available third-wave CBT intervention studies for cancer caregivers and targeted outcomes. Most of the interventions were dyadic interventions and utilized mindfulness. Delivery methods were continuously updated with digital technologies. Further RCTs with robust research designs and a synthesis of the results of the trials would provide evidence about how to effectively apply third-wave CBTs for cancer caregivers.

Effect of group-based acceptance and commitment therapy on older stroke survivors: study protocol for a randomized controlled trial

INTRODUCTION

Older stroke survivors usually experience various psychology disorders, such as post-stroke depression (PSD), which may be associated with high experiential avoidance (EA) and can seriously affect their quality of life. To date, the efficacy of group-based acceptance and commitment therapy (ACT) for older stroke survivors has not been established. The aim of this study is to investigate the effectiveness of group-based ACT on EA, PSD, psychological distress, and quality of life in older stroke survivors after group-based ACT.

METHODS AND ANALYSIS

This study is a randomized, single-blind, wait-list controlled, parallel-arm trial. A total of 66 stroke survivors will be randomly assigned to wait-list control group or intervention group. Participants in wait-list control group will receive treatment as usual (TAU), while the intervention group will receive group-based ACT once a week for eight weeks. The primary outcome measure being EA, and the secondary outcome measures being PSD, psychological distress, and quality of life. Results of the two groups will be blindly assessed by professional evaluators at baseline (T0), post-treatment (T1), and one-month follow up (T2).

DISCUSSION

The results of this study will provide the first evidence for the effectiveness of a group-based ACT intervention in reducing EA, PSD, psychological stress, and improving quality of life for post-stroke survivors.

Measurement of psychological inflexibility: an examination of the psychometric properties of the AAQ-3 compared to AAQ-II

Due to the limitations of the existing measurements of experiential avoidance, we would like to check the validity of the improved version of Acceptance and Action Questionnaire-II (AAQ-II), i.e., Acceptance and Action Questionnaire-3 (AAQ-3), in Chinese content. The present study was aim to examine the construct and validity of the Chinese version of AAQ-3 in college students and provide an initial validation of this instrument to promote future cross-cultural examination of the psychological flexibility. Totally 1,572 college students were invited to complete the Chinese AAQ-3 and the related questionnaires at the same time. After one month, 380 participates were assessed with same questionnaires to examine the test-retest reliability. The results indicated a similar one-factor solution in the Chinese AAQ-3 to the original version by exploratory factor analysis, parallel analysis and confirmatory factor analysis. Internal consistency and test-retest reliability were good. According to the testing of the measurement invariance, the one-factor model was acceptable across gender (Man = 875, Girl = 697). Additionally, Chinese AAQ-3 was significantly negatively correlated with positive mental health (life satisfaction, mindful attention awareness), significantly positively correlated with negative emotions (depression, anxiety, stress), and significantly positively correlated with AAQ-II and Brief Experiential Avoidance Questionnaire (BEAQ). Besides, Chinese AAQ-3 was the strongest predictor of depression, anxiety, stress and life satisfaction compared to the AAQ-II and BEAQ. However, according to the exploratory structural equation model, the Chinese AAQ-3 demonstrated excellent discriminate validity from negative emotions. Overall, the AAQ-3 modified the limitations of the existing measurements of experiential avoidance (i.e., AAQ-II and BEAQ) as it showed better convergent validity with positive mental health indicators, better discriminant validity with negative emotions, and higher incremental validity. Therefore, the Chinese AAQ-3 is a valid measurement tool for assessing the level of experiential avoidance or psychological flexibility in Chinese college students.

Short-Term Findings From Testing EPIO, a Digital Self-Management Program for People Living With Chronic Pain: Randomized Controlled Trial

BACKGROUND

Chronic pain conditions involve numerous physical and psychological challenges, and while psychosocial self-management interventions can be of benefit for people living with chronic pain, such in-person treatment is not always accessible. Digital self-management approaches could improve this disparity, potentially bolstering outreach and providing easy, relatively low-cost access to pain self-management interventions.

OBJECTIVE

This randomized controlled trial aimed to evaluate the short-term efficacy of EPIO (ie, inspired by the Greek goddess for the soothing of pain, Epione), a digital self-management intervention, for people living with chronic pain.

METHODS

Patients (N=266) were randomly assigned to either the EPIO intervention (n=132) or a care-as-usual control group (n=134). Outcome measures included pain interference (Brief Pain Inventory; primary outcome measure), anxiety and depression (Hospital Anxiety and Depression Scale), self-regulatory fatigue (Self-Regulatory Fatigue 18 scale), health-related quality of life (SF-36 Short Form Health Survey), pain catastrophizing (Pain Catastrophizing Scale), and pain acceptance (Chronic Pain Acceptance Questionnaire). Linear regression models used change scores as the dependent variables.

RESULTS

The participants were primarily female (210/259, 81.1%), with a median age of 49 (range 22-78) years and a variety of pain conditions. Analyses (n=229) after 3 months revealed no statistically significant changes for the primary outcome of pain interference (P=.84), but significant reductions in the secondary outcomes of depression (mean difference -0.90; P=.03) and self-regulatory fatigue (mean difference -2.76; P=.008) in favor of the intervention group. No other statistically significant changes were observed at 3 months (all P>.05). Participants described EPIO as useful (ie, totally agree or agree; 95/109, 87.2%) and easy to use (101/109, 92.7%), with easily understandable exercises (106/109, 97.2%).

CONCLUSIONS

Evidence-informed, user-centered digital pain self-management interventions such as EPIO may have the potential to effectively support self-management and improve psychological functioning in the form of reduced symptoms of depression and improved capacity to regulate thoughts, feelings, and behavior for people living with chronic pain.

Does older mean flexible? Psychological flexibility and illness cognitions in chronic medical conditions - the moderating effect of age

Adjustment to a Chronic Medical Condition (CMC) is associated with developing hypotheses regarding one's symptoms, known as illness cognition (IC). Aging is associated with a higher rate of CMC. We assessed the effects of aging and psychological flexibility (PF)-one's ability to be open to change, and to alter or persist in behaviors according to environmental circumstances - on IC development in CMC. In a cross-sectional study of hospitalized patients with CMC, 192 patients in four age groups: younger (<50), midlife (50-59), young old (60-69), and elderly (≥70) completed questionnaires sampling IC, PF and demographics. Younger participants reported less helplessness (IC) while lower scores in one PF component (perceiving reality as multifaceted) were reported by the elderly (≥70); older age was associated with a more fixed, narrow perception of reality. Both effects remained significant when using the medical condition severity as a covariate. In general, age was positively associated with IC of acceptance and Helplessness. In regression analysis, CMC severity significantly predicted all IC. Moreover, the interaction of age and perceiving reality as dynamic and changing (PF-RDC component) significantly predicted IC- acceptance of illness; follow-up analysis revealed significant correlations between PF-RDC and acceptance only for younger patients (< age 50). PF-RDC also significantly predicted IC - perceived benefit; among the entire sample higher RDC was associated with less IC - perceived benefit. Implications for theory and practice are discussed.

Acceptance and commitment therapy for individuals with depressive and anxiety symptoms following acquired brain injury: A non-concurrent multiple baseline design across four cases

Patients with acquired brain injury (ABI) often experience symptoms of anxiety and depression. Until now, evidence-based treatment is scarce. This study aimed to investigate the effectiveness of Acceptance and Commitment Therapy (ACT) for patients with ABI. To evaluate the effect of ACT for people with ABI, a non-concurrent multiple baseline design across four cases was used. Participants were randomly assigned to a baseline period, followed by treatment and then follow-up phases. Anxiety and depressive symptoms were repeatedly measured. During six measurement moments over a year, participants filled in questionnaires measuring anxiety, depression, stress, participation, quality of life, and ACT-related processes. Randomization tests and NAP scores were used to calculate the level of change across phases. Clinically significant change was defined with the Reliable Change Index. Three out of four participants showed medium to large decreases in anxiety and depressive symptoms (NAP = 0.85 till 0.99). Furthermore, participants showed improvements regarding stress, cognitive fusion, and quality of life. There were no improvements regarding psychological flexibility, value-driven behaviour, or social participation. This study shows that ACT is possibly an effective treatment option for people experiencing ABI-related anxiety and depression symptoms. Replication with single case or large scale group studies is needed to confirm these findings.

Moderators and mediators of change of an internet-based mindfulness intervention for college students: secondary analysis from a randomized controlled trial

Background

Existing evidence suggests internet- and mobile-based interventions (IMIs) improve depressive symptoms in college students effectively. However, there is far less knowledge about the potential mechanisms of change of mindfulness-based IMIs, which could contribute to optimizing target groups and interventions. Hence, within this secondary analysis of data from a randomized controlled trial (RCT), potential moderators and mediators of the effectiveness of the IMI StudiCare Mindfulness were investigated.

Methods

Moderation and mediation analyses were based on secondary data from a RCT that examined the effectiveness of the 7-module IMI StudiCare Mindfulness in a sample of college students (intervention group: n = 217; waitlist control group: n = 127). Assessments were collected before (t0; baseline), 4 weeks after (t1; during intervention), and 8 weeks after (t2; post-intervention) randomization. Longitudinal mediation analyses using structural equation modeling were employed, with depressive symptom severity as the dependent variable. For moderation analyses, bilinear interaction models were calculated with depressive symptom severity and mindfulness at t2 as dependent variables. All data-analyses were performed on an intention-to-treat basis.

Results

Mediation analyses showed a significant, full mediation of the intervention effect on depressive symptom severity through mindfulness (indirect effect, a*b = 0.153, p < 0.01). Only the number of semesters (interaction: β = 0.24, p = 0.035) was found to moderate the intervention's effectiveness on depressive symptom severity at t2, and only baseline mindfulness (interaction: β = -0.20, p = 0.047) and baseline self-efficacy (interaction: β = -0.27, p = 0.012) were found to be significant moderators of the intervention effect on mindfulness at t2.

Conclusion

Our results suggest a mediating role of mindfulness. Moderation analyses demonstrated that the intervention improved depressive symptom severity and mindfulness independent of most examined baseline characteristics. Future confirmatory trials will need to support these findings.
