Acceptance and Commitment Therapy in group format for anxiety and depression. A systematic review

The effect of an online acceptance and commitment intervention on the meaning-making process in cancer patients following hematopoietic cell transplantation: study protocol for a randomized controlled trial enhanced with single-case experimental design

BACKGROUND

Hematopoietic cell transplantation (HCT) is a highly invasive and life-threatening treatment for hematological neoplasms and some types of cancer that can challenge the patient's meaning structures. Restoring meaning (i.e., building more flexible and significant explanations of the disease and treatment burden) can be aided by strengthening psychological flexibility by means of an Acceptance and Commitment Therapy (ACT) intervention. Thus, this trial aims to examine the effect of the ACT intervention on the meaning-making process and the underlying mechanisms of change in patients following HCT compared to a minimally enhanced usual care (mEUC) control group. The trial will be enhanced with a single-case experimental design (SCED), where ACT interventions will be compared between individuals with various pre-intervention intervals.

METHODS

In total, 192 patients who qualify for the first autologous or allogeneic HCT will be recruited for a two-armed parallel randomized controlled trial comparing an online self-help 14-day ACT training to education sessions (recommendations following HCT). In both conditions, participants will receive once a day a short survey and intervention proposal (about 5-10 min a day) in the outpatient period. Double-blinded assessment will be conducted at baseline, during the intervention, immediately, 1 month, and 3 months after the intervention. In addition, 6-9 participants will be invited to SCED and randomly assigned to pre-intervention measurement length (1-3 weeks) before completing ACT intervention, followed by 7-day observations at the 2nd and 3rd post-intervention measure. The primary outcome is meaning-related distress. Secondary outcomes include psychological flexibility, meaning-making coping, meanings made, and well-being as well as global and situational meaning.

DISCUSSION

This trial represents the first study that integrates the ACT and meaning-making frameworks to reduce meaning-related distress, stimulate the meaning-making process, and enhance the well-being of HCT recipients. Testing of an intervention to address existential concerns unique to patients undergoing HCT will be reinforced by a statistically rigorous idiographic approach to see what works for whom and when. Since access to interventions in the HCT population is limited, the web-based ACT self-help program could potentially fill this gap.

Examining domains of psychological flexibility and inflexibility as treatment mechanisms in acceptance and commitment therapy: A comprehensive systematic and meta-analytic review

The current systematic and meta-analytic review sought to integrate a growing number of studies examining dimensions of psychological flexibility as treatment mechanisms for Acceptance and Commitment Therapy (ACT). Analyses of 77 records (67 unique studies; Ntotal = 9123 participants) from comprehensive searches of multiple databases suggested that ACT interventions led to reduced inflexibility (i.e., lowered global inflexibility, lack of present moment awareness, cognitive fusion, experiential avoidance, self-as-content, & inaction) and increased flexibility (i.e., committed action/contact with values, global flexibility/acceptance, & defusion). Those changes remained significant when ACT was compared with waitlist or active treatments and were significantly linked to corresponding drops in psychological distress, supporting their roles as ACT treatment mechanisms. Moderation analyses revealed that the use of student samples, exclusion of clinically symptomatic individuals, and comparisons of ACT with other active treatments weakened these effects whereas offering ACT as an individual therapy and excluding individuals in extreme crisis (i.e., with suicidal ideation) strengthened them. The meta-analytic findings and systematic review suggested specific recommendations for future clinical work and research on ACT mechanisms: (1) Evaluate both psychological flexibility and inflexibility as distinct treatment mechanisms, (2) Evaluate specific dimensions of psychological flexibility/inflexibility as mechanisms with multidimensional scales (CompACT, MPFI), (3) Broaden treatment outcomes to include forms of wellbeing (peace of mind, vitality, connectedness), (4) Assess mechanisms and outcomes repeatedly throughout treatment to model the process of therapeutic change, (5) Investigate non-specific factors (therapeutic alliance, treatment adherence) as mechanisms, and (6) Explore treatment mechanisms in effectiveness studies.

Personality and Pain Outcomes in Rheumatic Disease: The Mediating Role of Psychological Flexibility

BACKGROUND

Chronic pain is associated with increased disability and vulnerability to emotional disorders. Personality and psychological flexibility (PF) describe interindividual differences that shape the adjustment to chronic pain. Specifically, PF was found to be associated with pain, fatigue, anxiety, and depression intensity. Although previous studies established strong correlations between personality and pain outcomes, evidence on the nature of this relationship is scarce. Therefore, the objective of this study is to explore the mediating effect of PF on the relationship between personality and distress.

METHODS

This transversal study included 108 participants (age M = 56.7, SD = 11.3) diagnosed with musculoskeletal chronic pain. Self-reported measures were administered by the medical care team. Multiple mediation models were performed for estimating the indirect effects on each outcome variable.

RESULTS

After controlling for age and gender covariates, we found that PF completely mediated the relationship between personality traits and all pain outcomes and partially mediated the impact of extraversion on anxiety. In addition, emotional stability also had an indirect effect on anxiety through PF.

CONCLUSIONS

Personality traits and PF are significant predictors of pain outcomes. PF represents a core process mediating the impact of personality traits on the perceived intensity of pain, fatigue, anxiety, and depression in patients with rheumatic disease. These results could facilitate the application of individualized psychological interventions in clinical contexts targeting the reduction of emotional avoidance and in chronic pain patients.

Internet-based self-administered intervention to reduce anxiety and depression symptomatology and improve well-being in 7 countries: protocol of a randomized control trial

Background

Online psychological interventions have emerged as a treatment alternative because they are accessible, flexible, personalized, and available to large populations. The number of Internet interventions in Latin America is limited, as are Randomized Controlled Trials (RCTs) of their effectiveness and a few studies comparing their effectiveness in multiple countries at the same time. We have developed an online intervention, Well-being Online, which will be available to the public free of charge in 7 countries: Mexico, Ecuador, Peru, Chile, Brazil, Spain, and the Netherlands. We expect a reduction in depression and anxiety symptoms and an increase in well-being of the participants.

Methods

A multi-country, randomized controlled trial will be conducted. The intervention is multicomponent (Cognitive Behavioral Therapy, Behavioral Activation Therapy, Mindfulness, Acceptance and Commitment Therapy, and Positive Psychology), with 10 sessions. In each country, eligible participants will be randomized to one of three groups: Enriched Intervention (interactive web design with videos, infographics, text, audio, and forum), Text Intervention (text on the website), and Wait List (control group). Repeated measures will be obtained at 5-time points. Our primary outcomes will be anxiety symptomatology, depressive symptomatology, and mental well-being. MANOVA analysis will be used for our main analysis.

Discussion

This protocol describes the design of a randomized trial to evaluate the efficacy of a web-based intervention to reduce anxiety and depression symptomatology and increase subjective well-being. The intervention will be made available in four languages (Spanish, Portuguese, Dutch, and English). Its results will contribute to the evidence of effectiveness in terms of randomized trials and Internet interventions, mainly in Latin America and Europe.

Psychological flexibility in somatic symptom and related disorders: A case control study

A key diagnostic criterion of Somatic Symptom and related Disorders (SSD) comprises significant distress and excessive time-and-energy consuming thoughts, feelings, and behavior pertaining to somatic symptoms. This diagnostic criterion is lacking in central sensitivity syndromes (CSS), such as fibromyalgia, irritable bowel syndrome, and chronic fatigue syndrome. This strong emphasis on disturbed psychological processing of somatic symptoms, suggests that psychological flexibility is low in SDD. Psychological flexibility is defined as the ability to approach difficult or challenging internal states (thoughts, emotions, and bodily sensations) in a non-judgmental, mindful way, and being committed to pursue one's values. To clarify the potential significance of psychological flexibility in SSD, we examined its levels in 154 people referred to specialized treatment for SDD, as compared to reference groups from the general population encompassing 597 people with CSS and 1422 people without SSD or CSS (controls). Mean levels of psychological flexibility (adjusted for demographic covariates) were lowest for SSD and highest for controls (F = 154.5, p < 0.001, pη2 = 0.13). Percentages of people with low psychological flexibility (<0.8 SD below the mean of controls) were: SSD 74%, CSS 42%, controls 21%. In SSD, higher psychological flexibility was associated with better mental health (β = 0.56, p < 0.001), but interaction analysis rejected that psychological flexibility preserved health when having more severe somatic symptoms (β ≤ 0.08, p ≥ 0.10). The results indicate that lower psychological flexibility is a prevalent problem in SSD that is associated with lower mental health. This suggests that it is worthwhile to take account of psychological flexibility in SSD in screening, monitoring, and therapy.

Psychosocial intervention programme based on the needs of women undergoing termination of pregnancy for foetal anomalies: A modified Delphi study

AIM

To construct a psychosocial intervention programme for women diagnosed with foetal anomalies based on their needs in China.

DESIGN

A three round-modified Delphi survey from September to November 2020.

METHODS

In Round 1, based on literature review and qualitative interviews, a face-to-face meeting with eight taskforce members was conducted to generate the initial intervention indicators. In Round 2 and 3, 15 experts and three stakeholders (women undergoing termination of pregnancy for foetal anomalies) were invited by email to evaluate the importance of the indicators and built the final psychosocial intervention programme.

RESULTS

The response rate for both two rounds is 100%. The experts' authority coefficient was 0.86. The Kendall W value of the two rounds ranged between 0.191 and 0.339. A needs-based psychosocial intervention programme was established, including four periods (denial, confirmation, decision-making and recovery), three needs-based supports (information, social and acceptance commitment therapy) and 27 intervention indicators. The mean value of the importance of each index was 4.00-5.00. Further research is required to evaluate whether this programme is realistic and effective for the target audiences.

Evaluation of Implementation Strategies for Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), and Mindfulness-Based Stress Reduction (MBSR): a Systematic Review

BACKGROUND

Improving access to evidence-based psychotherapies (EBPs) is a Veterans Health Administration (VHA) priority. Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based stress reduction (MBSR) are effective for chronic pain and several mental health conditions. We synthesized evidence on implementation strategies to increase EBP access and use.

METHODS

We searched MEDLINE, Embase, PsycINFO, and CINAHL from inception until March 2021 for articles on EBP implementation within integrated health systems to treat chronic pain or chronic mental health conditions. Reviewers independently screened articles, extracted results, coded qualitative findings, and rated quality using modified criteria from Newcastle-Ottawa (quantitative results) or Critical Appraisal Skills Programme (qualitative results). We categorized implementation strategies using the Expert Recommendations for Implementing Change (ERIC) framework and classified outcomes using RE-AIM domains (Reach, Effectiveness, Adoption, Implementation, Maintenance).

RESULTS

Twelve articles (reporting results from 10 studies) evaluated CBT (k = 11) and ACT (k = 1) implementation strategies in large integrated healthcare systems. No studies evaluated MBSR implementation. Eight articles evaluated strategies within VHA. Six articles reported on national VHA EBP implementation programs; all involved training/education, facilitation, and audit/feedback. CBT and ACT implementation demonstrated moderate to large improvements in patient symptoms and quality of life. Trainings increased mental health provider self-efficacy in delivering EBPs, improved provider EBP perceptions, and increased provider EBP use during programs, but had unclear impacts on Reach. It was unclear whether external facilitation added benefit. Provider EBP maintenance was modest; barriers included competing professional time demands and patient barriers.

DISCUSSION

Multi-faceted CBT and ACT implementation programs increased provider EBP Adoption but had unclear impacts on Reach. Future implementation efforts should further evaluate Reach, Adoption, and Maintenance; assess the added value of external facilitation; and consider strategies targeting patient barriers. Future work should use implementation frameworks to guide evaluations of barriers and facilitators, processes of change, and outcomes.

Psychological distress and treatment preferences among parents amidst the COVID-19 pandemic

The COVID-19 pandemic has presented many stressors for parents. This study was conducted to examine treatment preferences and barriers to care amidst COVID-19. Parents (N ​= ​95) completed self-report measures. Education was provided on interventions (e.g., individual therapy, medication), and acceptability assessed. Elevated stress and distress were observed. Parents indicated interest in services for parenting concerns, stress, anxiety, and depression. Individual therapy and telehealth were highly acceptable, while medication and group therapy were less accepted. Findings highlight the need for specific supports among parents amidst the pandemic. Factors that influence treatment preference warrant further attention. Implications for healthcare service delivery are discussed.

Forced social isolation and lockdown during the COVID-19 pandemic: depression, anxiety, trauma-distress and coping mechanisms of a Greek sample

Aim

The COVID-19 outbreak escalated into a global pandemic, pushing many governments around the world to impose measures affecting all aspects of life. Similar to other countries, Greece adopted social restriction, lockdowns, and quarantines to reduce transmission from person-to-person. This cross-sectional study investigated the association between social restriction measures, an mental health and coping strategies employed by a Greek adult sample.

Subject and methods

An online questionnaire was used to collect data during the second national lockdown (February to May 2021). A total of 650 participants (M age 33.13, 71.5% female) comprised the final sample.

Results

The results show 21.3% of respondents reported moderate-to-extremely severe anxiety, 33% moderate-to-extremely severe depression, 31.8% moderate-to-severe stress, and 38% clinically significant trauma-related distress. Hierarchical linear regression analyses revealed that the strongest contributors to adverse mental health outcomes were being female, of younger age, experiencing increases in verbal arguments at home, being separated from family and close friends, and being unable to afford enough or healthy food. Lastly, participants reported moving away from social support and into more individual strength and resilience-based coping strategies to cope with challenges.

Conclusion

These findings suggest that in addition to the detrimental effects on physical health, social restriction measures related to COVID-19 also imposed a heavy psychological burden on the population via forced social isolation, which, by design, increased not only physical distancing but also psychological distancing between people.

The efficacy of acceptance and commitment therapy for chronic pain: A three-level meta-analysis and a trial sequential analysis of randomized controlled trials

The current study included randomized controlled trials (RCTs) to assess the benefits of Acceptance and commitment therapy (ACT) for chronic pain. Searches were conducted in Web of Science, PsycINFO, PubMed, Scopus, Cochrane Library, and Embase from inception until September 30, 2022. Thirty-three RCTs, including 2293 participants, were included. Small to medium effect sizes for pain intensity/physical function favoring ACT were found both at post-treatment (pain intensity: g = 0.44; physical function: g = 0.59) and follow-up (pain intensity: g = 0.34; physical function: g = 0.56). The effect sizes on psychological outcomes were significant at post-treatment (depression: g = 0.43; anxiety: g = 0.43; quality of life: g = 0.45) and follow-up (depression: g = 0.43; anxiety: g = 0.35; quality of life: g = 0.43). The results of the trial sequential analyses indicated that pooled estimates were unlikely to be incidental findings, as effects of multiple testing were controlled and power was adequate. Face-to-face ACT yielded significantly larger effects on physical outcomes than internet-delivered ACT. Participants with chronic headache and fibromyalgia showed greater benefit from ACT compared to those with non-specific pain or mixed pain. In addition, the longer the follow-up duration, the smaller the effect sizes for pain intensity/physical function at follow-up. The present meta-analysis suggests sufficient evidence for the significant benefits of ACT for people with chronic pain.

Effects of acceptance and commitment therapy on cognitive function: A systematic review

Cognitive function is essential for daily activities. Acceptance and commitment therapy (ACT) may improve cognitive function by enhancing psychological flexibility, but the underlying mechanism is unknown. This systematic review evaluated the effectiveness of ACT on cognitive function. Seven research databases (PubMed, ProQuest Dissertations and Theses, Web of Science, EBSCOhost, CNKI, Scopus, Wanfang) were searched to collect articles with trials published in English and Chinese. After applying inclusion and exclusion criteria, we identified 12 studies published between 1994 and 2022 that included a combined total of 904 participants. Among the included studies were within-group (N = 3) and randomized controlled trial (RCT, N = 9) study designs. Outcome measures included cognitive scales and behavioral measurements. Of the 12 articles, 10 studies showed improvements in certain domains of cognitive function due indirectly to ACT intervention. We found that the ability of ACT intervention to promote psychological flexibility is due to its transdiagnostic nature. Also, the effects of the ACT intervention were observed in multiple cognitive domains: attention, subjective cognitive function, executive function, and memory. In conclusion, cognitive trainers could consider practicing ACT as part of their strategy to enhance an individual's psychological flexibility and cognitive function.

Effects of a Video Sequence Based Intervention on Anxiety, Fatigue and Depression in Cancer Patients: Results of a Randomized Controlled Trial

BACKGROUND

Cancer patients often suffer from psychological symptoms and need psychological support. Especially during the COVID-19 pandemic, eHealth interventions might be helpful to overcome the obstacles of the pandemic. This study evaluates the effectiveness of a video sequence-based eHealth intervention on anxiety, fatigue, and depression in cancer patients.

METHODS

Patients (N = 157) with different tumor entities were randomly assigned to the video intervention group (IG) and the waiting control group (CG). Patients in the IG received a video intervention comprising 8 video sequences over 4 weeks. The videos included psychoeducation on distress and psychological symptoms, Acceptance and Commitment Therapy elements, and Yoga and Qigong exercises. Patients' anxiety and fear of progression (primary outcomes) and secondary outcomes were assessed before randomization (T1) and after the end of the intervention for IG or the waiting period for CG (T2) using self-reported questionnaires (GAD-7, PA-F-KF, EORTC QLQ-FA12, PHQ-8).

RESULTS

Patients of the IG showed no significant improvement in anxiety (GAD-7; P = .75), fear of progression (FoP-Q-SF; P = .29), fatigue (EORTC QLQ-FA12; P = .72), and depression (PHQ-8; P = .95) compared to patients in the waiting CG. However, symptoms of anxiety, fatigue, and depression decreased in both groups. Exploratory subgroup analysis regarding sex, therapy status, therapy goal, and tumor entity showed no effects. Overall, the intervention had a high level of acceptance.

CONCLUSIONS

The video intervention was ineffective in reducing the psychological burden compared to a waiting CG. The findings support prior observations of the value of therapeutic guidance and promoting self-management for improving patients' psychological burdens. Further studies are required to evaluate the effectiveness of psycho-oncological eHealth delivered through video sequences.

Telehealth treatment of patients with major depressive disorder during the COVID-19 pandemic: Comparative safety, patient satisfaction, and effectiveness to prepandemic in-person treatment

BACKGROUND

The COVID-19 pandemic impelled a transition from in-person to telehealth psychiatric treatment. There are no studies of partial hospital telehealth treatment for major depressive disorder (MDD). In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we compared the effectiveness of partial hospital care of patients with MDD treated virtually versus in-person.

METHODS

Outcome was compared in 294 patients who were treated virtually from May 2020 to December 2021 to 542 patients who were treated in the in-person partial program in the 2 years prior to the pandemic. Patients completed self-administered measures of patient satisfaction, symptoms, coping ability, functioning, and general well-being.

RESULTS

In both the in-person and telehealth groups, patients with MDD were highly satisfied with treatment and reported a significant reduction in symptoms from admission to discharge. Both groups also reported a significant improvement in positive mental health, general well-being, coping ability, and functioning. A large effect size of treatment was found in both treatment groups. Contrary to our hypothesis, the small differences in outcome favored the telehealth-treated patients. The length of stay and the likelihood of staying in treatment until completion were significantly greater in the virtually treated patients.

LIMITATIONS

The treatment groups were ascertained sequentially, and telehealth treatment was initiated after the COVID-19 pandemic began. Outcome assessment was limited to a self-administered questionnaire.

CONCLUSIONS

In an intensive acute care setting, delivering treatment to patients with MDD using a virtual, telehealth platform was as effective as treating patients in-person.

Outcomes of Acceptance and Commitment Therapy for depression and predictors of treatment response in Veterans Health Administration patients

BACKGROUND

Acceptance and Commitment Therapy for depression (ACT-D) is a promising depression treatment which has not been evaluated on a large scale within VA. This study aimed to evaluate ACT-D's effectiveness in a national, treatment-seeking sample of Veterans.

METHODS

The sample comprised 831 Veterans who received a primary depression diagnosis and received at least two sessions of ACT-D during fiscal years 2015-2020. We used GLM to measure predictors of symptom change, treatment response (50 % reduction in PHQ-9 and AAQ-II scores), subthreshold depression symptoms (PHQ-9 < 10; AAQ-II < 27), and treatment completion.

RESULTS

Veterans experienced an average reduction of 3.39 points on the PHQ-9 (Cohen's d = 0.56) and 3.76 points on the AAQ-II (Cohen's d = 0.43). On the PHQ-9, 40 % achieved subthreshold depression symptoms. On the AAQ-II, 36 % of Veterans achieved subthreshold psychological inflexibility scores. Service-connected disability rating for depression and higher levels of medical comorbidity were both related to lower levels of overall depression symptom change and treatment response. Substance use disorder and bipolar/psychosis diagnoses were associated with greater reductions in psychological inflexibility.

LIMITATIONS

This is an observational study without a control group, so we were unable to compare the effectiveness of ACT-D to other usual care for depression. We were also unable to assess variables that can influence treatment success, such as therapist fidelity and patient engagement.

CONCLUSIONS

ACT-D achieved similar improvements in depression as reported in controlled trials. Adaptations to ACT-D may be needed to improve outcomes for Veterans with depression and comorbid PTSD.

Exploring the path of persisting dysfunctional expectations-Development of the immunization scale IMS

Objectives

Persistent dysfunctional expectations seem to be core features of mental disorders. The aim of this study was to develop a questionnaire that assesses mechanisms responsible for the consistency of dysfunctional expectations. Processes before (i.e., assimilation) and after (i.e., immunization) expectation-violating experiences have been considered.

Design

The Immunization Scale (IMS) is constructed and validated with the help of an explorative (EFA) and confirmatory factor analysis (CFA) in two conducted studies.

Materials and methods

For the first study, the initially formulated 75-item version was completed online by 230 (range 18-69) participants from a convenience sample. For the second study, 299 (range 18-62) participants completed the reduced scale at the first measurement point, 75 participants thereof also 1 month later. For validity and reliability analyses, participants in both studies provided demographic information, the Beck Depression Inventory (BDI-II), the Depressive Expectation Scale (DES), the Beck Anxiety Inventory (BAI), and the German version of the Acceptance and Action Questionnaire (FAH-II).

Results

The initial 75 items were reduced to 23 items. The EFA revealed three main factors, namely, negative expectations, assimilation, and cognitive immunization. The three-factor structure could be confirmed in study 2 by the CFA. Reliability measures showed an excellent internal consistency for the entire IMS. A very good test-retest reliability was found. Significant correlations resulted between the IMS and DES, BDI-II, BAI, and FAH-II, the highest for DES and FAH-II.

Conclusion

Psychometric properties of the IMS are promising. Future studies should verify the reliability and validity measures in other population samples. The IMS can be very useful in expectation research, especially in the examination of expectation-focused therapy.

Acceptance and commitment therapy for episodic migraine: Rationale and design of a pilot randomized controlled trial

Migraine is a debilitating disorder with limited pharmacological options. Many migraine medications can have intolerable side effects leading patients to seek complementary and integrative health (CIM) approaches for treatment. One option that is growing in popularity and evidence is Acceptance and Commitment Therapy (ACT), a mindfulness-based therapy. The purpose of this paper is to describe how ACT may be an effective modality integrated into the treatment of migraine and to describe the design of a pilot study of ACT for migraine. First, we review the research and the promise of mindfulness therapies for the treatment of migraine. Then, we describe how ACT differs from other mindfulness therapies for migraine and why it can be a promising option for these patients. Finally, we summarize the design of a pilot study designed to determine the feasibility of performing a future fully powered study to determine the effectiveness of ACT on migraine frequency and disability. This pilot study includes unique features, including a remotely-delivered ACT intervention and the measurement of cortisol levels before and after the intervention.

Comparative effectiveness and acceptability of different ACT delivery formats to treat depression: A systematic review and network meta-analysis of randomized controlled trials

BACKGROUND

Acceptance and Commitment Therapy (ACT) has been shown to be effective in the treatment of acute depression. However, whether ACT can be effectively delivered in individual, group, internet, and combined delivery format remain unclear. We aimed to examine the most effective delivery format for ACT via a network meta-analysis (NMA).

METHODS

An electronic literature search was conducted by two reviewers in the Pubmed, Cochrane library, Embase, PsycINFO, CINAHL, CNKI, Wangfang databases to identify relevant studies that were published up to March 21th, 2021. We conducted pairwise and NMA to evaluate the relative effectiveness and rank the probability of different ACT delivery formats. A series of analyses and assessments, such as the risk of bias, and GRADE were performed concurrently.

RESULTS

A total of 23 studies were included in our analysis based on a series of rigorous screenings, which comprised 690 depressed patients. The effectiveness of individual, group, internet, and combine ACT did not differ statistically significantly from each other. Compared with control group, individual delivery format (standardized mean difference [SMD] = -1.44, confidence interval (CI) = -2.11 to -0.76 GRADE low), group delivery format (SMD = -1.34, 95 % CI = -1.91 to -0.78 GRADE moderate), and internet delivery format (SMD = -0.66, 95 % CI = -1.25 to -0.06 GRADE low) showed the largest improvement on depressive symptoms, whereas the combined group and individual ACT was less effective. In terms of acceptability (dropout for any reason), all delivery formats did not differ statistically significantly from each other.

CONCLUSIONS

For depression symptoms, individual, group, and internet treatment formats appeared to be effective interventions. Applying effective and acceptable ACT in a range of different formats will make ACT easier to implement, disseminate, and deliver across different settings and diverse patient populations. More research is needed to verify the ACT in telephone and combined formats for the management of depression.

The Effects of COVID-19-Related Stress on Depression in Working Mothers with School-Aged Children: The Moderated Mediation Effect of Parenting Efficacy and Cognitive Flexibility

Objectives: This study aimed to analyze the effects of COVID-19-related stress, parental efficacy, and cognitive flexibility on depression of mothers with school-aged children and to examine a moderated mediation model.Methods: Data on cognitive flexibility, parental efficacy, COVID-19-related stress, and depression were collected from 441 working mothers who had at least one school-aged child using the Cognitive Flexibility Inventory (CFI) and Parenting Sense of Competence (PSOC), COVID Stress/Disruption, and Center for Epidemiologic Studies Depression (CES-D) scales. Data were then analyzed using SPSS 26.0, and PROCESS macro version 4.0.Results: The findings revealed that COVID-19-related stress had a significant positive influence on depression in working mothers, which was mediated by parental efficacy. A moderated mediation analysis further indicated that this indirect effect varied depending upon the mothers’ sense of control a sub-factor of cognitive flexibility. Therefore, when mothers perceived they were unlikely to exercise any control over changes caused by the COVID-19 pandemic, their parental efficacy exerted a greater mediating effect.Conclusion: Results suggest that interventions reducing COVID-19-related stress and increasing parental efficacy could alleviate depression among working mothers with school-aged children. Furthermore, cognitive interventions could be effective in helping those working mothers experiencing a low level of parenting efficacy due to COVID-19-related stress to perceive the demanding situation as within their control.

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.

Effects of group Acceptance and Commitment Therapy (ACT) on anxiety and depressive symptoms in adults: A meta-analysis

BACKGROUND

A comprehensive meta-analysis quantitatively examining the effects of group Acceptance and Commitment Therapy (ACT) on anxiety and depressive symptoms is required to advance our understanding of its efficacy and moderating factors.

METHODS

Four electronic databases were searched in August 2018. An update search was conducted in November 2021. Forty-eight randomised controlled trials (RCTs) were included in this review (3292 participants: anxiety = 34 RCTs, depression = 40 RCTs).

RESULTS

The overall effect size for anxiety symptoms was medium-to-large (g = 0.52, p < 0.001; 95% CI = 0.30-0.73), while the overall effect size was small-to-medium for depressive symptoms (g = 0.47, p < 0.001; 95% CI = 0.31-0.64). Subgroup analyses demonstrated that group ACT was significantly superior to non-active controls (e.g., waiting list) in reducing anxiety and depressive symptoms. Group ACT was only significantly superior to active controls (e.g., CBT) in reducing depressive symptoms. Subgroup analyses also demonstrated that the effect size can vary depending on the number of sessions provided and the primary condition of participants recruited.

LIMITATIONS

The number of studies included in each category of subgroup analyses was small and the risk of bias varied across studies. There was high heterogeneity among the included studies, and this might have affected the results.

CONCLUSION

The current evidence suggests that group ACT may be effective in treating anxiety and depressive symptoms, perhaps more so for depressive symptoms when compared to other well-established treatments. The intensity of treatment and the targeted population may need to be considered when delivering group ACT.

Is Activation the Active Ingredient of Transdiagnostic Therapies? A Randomized Clinical Trial of Behavioral Activation, Acceptance and Commitment Therapy, and Transdiagnostic Cognitive-Behavioral Therapy for Emotional Disorders

Studying the usefulness of contextual and cognitive transdiagnostic therapies calls for an analysis of both their differential efficacy and their specificity when acting on the transdiagnostic conditions on which they focus. This controlled trial compares the post-treatment and 3- and 6-month follow-up effects of Behavioral Activation (BA), Acceptance and Commitment Therapy (ACT) and Cognitive-Behavioral Transdiagnostic Therapy (TD-CBT) on emotional symptomatology, and analyses the role played by Experiential Avoidance, Cognitive Fusion, Activation and Emotion Regulation in the clinical change. One hundred twenty-eight patients who fulfilled diagnostic criteria for anxiety and/or depression (intention-to-treat sample) were randomly assigned to three experimental group-treatment conditions (BA, n = 34; ACT, n = 27; TD-CBT n = 33) and one control group (WL, n = 34). Ninety-nine (77.34%) completed the treatment (per-protocol sample). In the post-treatment, all therapies reduced anxiety and depression symptomatology. In the follow-ups, the reduction in emotional symptomatology was greater in the condition which produced greater and more prolonged effects on Activation. Activation appears to be the principal condition in modifying all the transdiagnostic patterns and BA was the most efficacious and specific treatment. The trial was registered at ClinicalTrials.gov NCT04117464. Raw data are available online http://dx.doi.org/10.17632/krj3w2hfsj.1 .

ACT em Grupo para Manejo de Ansiedade entre Universitários: Ensaio Clínico Randomizado

Resumo Estima-se que um a cada cinco estudantes universitários ao redor do mundo apresenta algum tipo de transtorno psicológico, dentre os quais os transtornos de ansiedade são os mais prevalentes. Este estudo consiste em um ensaio clínico randomizado com o objetivo de avaliar a eficácia e efetividade de um protocolo semiestruturado de psicoterapia em grupo baseado nos princípios da Terapia de Aceitação e Compromisso (ACT) para o tratamento de ansiedade entre estudantes universitários. Os participantes foram alocados aleatoriamente entre os grupos intervenção e controle. Os níveis de ansiedade pré e pós-intervenção foram avaliados por meio do instrumento General Anxiety Disorders-7 (GAD-7). A amostra final do estudo foi composta por 15 pessoas, dentre as quais 10 foram alocadas no grupo intervenção e 5, no grupo controle. Os resultados foram analisados de duas formas: a) por protocolo (Per-protocol analysis); e b) por intenção de tratar (Intention-to-treat Analysis). Este tratamento reduziu a sintomatologia ansiosa em 39,7% entre os pacientes que completaram o tratamento (por protocolo, p=0,030) e em 30,8% entre todos alocados para o grupo intervenção (i.e., por intenção de tratar, incluindo os dropouts, p=0,035), enquanto os controles não tiveram redução significativa no mesmo período. Portanto, recomenda-se a utilização deste protocolo dentro do contexto universitário como uma alternativa viável ao acompanhamento individual em situações de transtornos de ansiedade. Pesquisas futuras com amostras maiores podem contribuir na consolidação deste protocolo.

The effects of acceptance and commitment therapy on psychosocial impact and adherence of MDR-TB patients

Background: The Worldwide resistance prevalence of the first-line tuberculosis drug, rifampicin, in 2017 was 7.4 per 100,000 population, and 82% of them experienced multidrugresistant tuberculosis (MDR-TB). Indonesia is the top 20 country with an MDR-TB burden, and its prevalence is 8.8 per 100,000 population. MDR-TB requires a long-time treatment and has accompanying side effects: biological and psychosocial effects. However, efforts to overcome the psychosocial impacts have not been conducted. This study aims to determine the effect of acceptance and commitment therapy (ACT) on anxiety, depression, suicidal ideation, and treatment adherence in MDR-TB patients.

Design and methods: This research employed a quasi-experimental design with a pre-test three post-tests using total sampling. The pre-test was conducted before the standard nursing intervention, post-test 1 was after the standard nursing intervention, posttest 2 was after ACT session 1, and post-test 3 was after ACT session 2. Data were collected by the Hamilton Rating Scale for Anxiety, Beck Hopelessness Scale, a Scale for Suicide Ideation, and Morisky Medication Adherence Scale.

Results: The standard nursing action and ACT reduce anxiety (p=0.002), reduced depression (p=0.0001), reduced suicidal ideation (p=0.008), and increased treatment adherence (p=0.0001).

Conclusions: The standard nursing action and ACT reduce anxiety, depression, and suicidal ideation. They increase treatment adherence recommended for use in MDR-TB patients.

Validation of the Acceptance and Action Questionnaire-II in the general Spanish population

Acceptance and Commitment Therapy states that Experiential Avoidance contributes to the development of psychological issues. The Acceptance and Action Questionnaire-II measures Experiential Avoidance. The objective of the current study is to perform a validation of the Acceptance and Action Questionnaire-II in the general Spanish population. A sample of 964 participants from all over Spain was used (M = 43.43 years; SD = 15.27). The psychometric properties of the questionnaire were examined according to Classical Test Theory. In addition, assessments were made of participants’ personality, Emotional Intelligence, Anxiety, and Depression, and the influence of sex and age on Experiential Avoidance was examined. The Acceptance and Action Questionnaire-II is a unidimensional instrument, with excellent reliability (α = .93) and adequate evidence of validity. Differences were observed based on sex, with women scoring higher, and based on age, with lower scores in the older age groups. The Acceptance and Action Questionnaire-II is a valid, reliable instrument for use in the general Spanish population.

Effectiveness of self-help plus (SH+) in reducing anxiety and post-traumatic symptomatology among care home workers during the COVID-19 pandemic: a randomized controlled trial

This article describes a randomized controlled trial to evaluate the effectiveness of a supervised online delivery of self-help plus (SH+), during the second wave of COVID-19 contagions in Northern Italy. The SH+ is a psychological intervention developed by the World Health Organization to increase a person's ability to deal with stress. In this trial, it was tested primarily as a tool to reduce anxiety and post-traumatic symptomatology in workers of residential nursing and care homes. In order to partial out non-specific effects of the intervention, the SH+ was compared to an equally supervised and structured alternative activity. Secondarily, in view of future emergencies, the potential of SH+ as a tool to reduce perceived stress, increase subjective well-being and foster individual resilience was explored. At post-intervention, the preregistered analysis revealed no difference in self-reported anxiety and/or post-traumatic symptomatology between the group receiving the SH+ and the group engaged in an alternative activity. Some specific and positive effects of the SH+ intervention were only found on self-reported intervention effectiveness and engagement in exploratory analyses. These findings raise the question whether the previously documented effectiveness of the SH+ on self-reported symptomatology and on the prevention of psychiatric conditions could be attributed mostly to non-specific rather than specific factors connected with participant enrolment in a psychological intervention. Indeed, the effects of the SH+ had been previously compared only to the effects of not being engaged in any alternative activity (often described in the literature as 'treatment as usual'-or 'enhanced treatment as usual', when some relevant information is given to the control group as a one-off). Given the negative findings of this study, before the SH+ is implemented in clinical practice, further studies should be conducted to examine its short- and long-term beneficial effects, by means of randomized studies that employ alternative but similarly structured interventions as control conditions, aiming to minimize the confounding effect of non-specific factors.

A systematic review and meta-analysis of acceptance- and mindfulness-based interventions for DSM-5 anxiety disorders

This meta-analysis systematically reviewed the evidence on standardized acceptance-/mindfulness-based interventions in DSM-5 anxiety disorders. Randomized controlled trials examining Acceptance and Commitment Therapy (ACT), Mindfulness-Based Cognitive Therapy (MBCT), and Mindfulness-Based Stress Reduction (MBSR) were searched via PubMed, Central, PsycInfo, and Scopus until June 2021. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated for primary outcomes (anxiety) and secondary ones (depression and quality of life). Risk of bias was assessed using the Cochrane tool. We found 23 studies, mostly of unclear risk of bias, including 1815 adults with different DSM-5 anxiety disorders. ACT, MBCT and MBSR led to short-term effects on clinician- and patient-rated anxiety in addition to treatment as usual (TAU) versus TAU alone. In comparison to Cognitive Behavioral Therapy (CBT), ACT and MBCT showed comparable effects on both anxiety outcomes, while MBSR showed significantly lower effects. Analyses up to 6 and 12 months did not reveal significant differences compared to TAU or CBT. Effects on depression and quality of life showed similar trends. Statistical heterogeneity was moderate to considerable. Adverse events were reported insufficiently. The evidence suggests short-term anxiolytic effects of acceptance- and mindfulness-based interventions. Specific treatment effects exceeding those of placebo mechanisms remain unclear.

Education of the primary health care staff based on acceptance and commitment therapy is associated with reduced sick leave in a prospective controlled trial

Background

The use of cognitive behavioral therapy (CBT) to cope with mental distress and pain issues has helped many patients in primary health care in Sweden. However, the effects of CBT to reduce sick leave has not been equally convincing. Acceptance and Commitment Therapy (ACT) is an evolution of traditional CBT and we aimed to study if education based on ACT of the staff rather than the patients could reduce sick leave in primary health care.

Methods

This was a prospective trial in 6 primary health care centers in Kalmar (total amount of registered subjects of 28,930) in which the staff (physicians, nurses and therapists) received group-based education according to ACT during 2018 and 2019. The effects were compared with 5 similarly sized control health care centers in the neighboring Region of Jönköping in which no such education took place. The main aim was to study changes in sick leave in the 6 primary care centers of Kalmar and to keep track of more general trends by studying sick leave also in Jönköping, letting sick leave in the year 2017 to be the reference period for both areas.

Results

The staff at the health care centers in Kalmar reported to having attended a mean of 5.2 ± 2 educational ACT-sessions with psychiatrist Kadowaki in Kalmar. Sick leave for ICD-10 F43 (reaction to severe stress and related adjustment-disorders) was reduced from a mean value of 28.7 ± 9.1ongoing sick leaves/month in 2017 to 22.6 ± 7.0 sick leaves/month in 2018 (-21%, p = 0.033) and to 18.1 ± 10 sick leaves/month in 2019 (-37%, p = 0.038). The corresponding sick leave for any diagnosis (total sick leave) was reduced from 132 ± 39 sick leaves/month in 2017 to 118 ± 38 sick leaves/month in 2018 (-11%, p = 0.056) and to 102 ± 37 sick leaves/month in 2019 (-21%, p = 0.021). The corresponding sick leave comparisons in the control health centers did not show any significant changes (all p-values ≥ 0.24).

Conclusions

Total monthly mean sick leave was reduced 21% in the health care centers in Kalmar during the second year of the educational ACT intervention of the staff while it was unchanged in Jönköping. This suggests a significant effect to induce a reduction in long-term sick leave for patients in primary health care in which the staff received education according to ACT. The results of this trial could serve as a basis for a randomized trial in order to ascertain causality.

"Comprehensive Assessment of ACT Processes CompACT. Romanian Adaptation and Short Form Validation"

"The current paper presents the translation and validation for Romanian non-clinical population of Comprehensive Assessment of ACT Processes – CompACT (Francis et al., 2016), an instrument that evaluates three dimensions of psychological flexibility: openness to experience, present moment awareness (mindfulness) and valued action. The psychometric properties of the Romanian version of the instrument were investigated, convergent validity in relation with AQQ-II and concurrent validity in relation with DASS-21 (with comparable results with ones reported for the original instrument). Considering modest model fit with theoretical factor structure of the instrument, current paper proposes a shorter, more stable Romanian Version, and tests its psychometric properties."

Do quality of life, anxiety, depression and acceptance improve after interdisciplinary pain rehabilitation? A multicentre matched control study of acceptance and commitment therapy-based versus cognitive-behavioural therapy-based programmes

OBJECTIVE

Interdisciplinary pain rehabilitation (IPR) usually employs a cognitive-behavioural therapeutic (CBT) approach. However, there is growing support for chronic pain treatments based on acceptance and commitment therapy (ACT). Most studies of ACT and CBT for chronic pain have evaluated their effects after psychological interventions, not after IPR. We compared the results of an ACT-based IPR programme with two CBT-based IPR programmes.

METHODS

We used a retrospective multicentre pretest-posttest design with matched patient groups at three centres. Data were collected from the Swedish Quality Registry for Pain Rehabilitation before and after IPR participation. Participants completed the EQ-5D health-related quality of life questionnaire, the Chronic Pain Acceptance Questionnaire, (CPAQ) and the Hospital Anxiety and Depression Scale (HADS). Analyses were performed to compare the effects of the different interventions.

RESULTS

Neither EQ-5D nor HADS depression scores were affected by the psychological approach used. The score changes on both CPAQ subscales (activity engagement and pain willingness) indicated significant improvements between admission and discharge at all centres.

CONCLUSIONS

These findings indicate the effectiveness of using psychological approaches to manage chronic pain. Both CBT and ACT had a beneficial effect on most of the assessed health-related parameters.

Online Acceptance and Commitment Therapy and Nutrition Workshop for Parents of Children with Inflammatory Bowel Disease: Feasibility, Acceptability, and Initial Effectiveness

Parents of children with inflammatory bowel disease (IBD) are important members of their healthcare team and influence their child’s adaptation to disease. The primary aim of this research was to test the feasibility and acceptability of a three-session online parent workshop based on acceptance and commitment therapy (ACT) and address concerns about eating well and nutrition in IBD. The secondary aim was to explore the initial effectiveness of this workshop in parent reported psychological flexibility, mindfulness, experiential avoidance, cognitive fusion, valued living, and symptoms of depression, anxiety, and stress. We used a single arm pragmatic prospective study design with parents of children attending the IBD program at a tertiary pediatric healthcare centre in Canada. Mixed methods patient reported outcomes were measured at baseline, immediate post participation, and 3 months post participation in the workshop. Thirty-seven parents enrolled in the study and feasibility and acceptability goals were largely met. Parents qualitatively described changes to their parenting, what aspects of the workshop were most helpful, and targeted feedback on how to improve workshop. Findings suggest that providing parents of children with IBD a brief online ACT workshop including nutrition guidance is feasible and leads to changes in parenting behaviours.

Web-based Acceptance and Commitment Therapy (ACT) for symptoms of anxiety and depression: Within-group effect size benchmarks as tools for clinical practice

COVID-19 has highlighted the need for evidence-based behavioural health interventions that can be delivered remotely. This article provides within-group effect size benchmarks for randomised controlled trials of Internet-based Acceptance and Commitment Therapy for the treatment of adults with anxiety and depression. Effect sizes were calculated using the Glass approach, adjusted using Hedges g, then aggregated to produce separate benchmarks for measures of anxiety and depression. These benchmarks can be used by community-based treatment providers to evaluate the effectiveness of their web-based Acceptance and Commitment Therapy intervention to determine if it should be continued, modified for the unique needs of their client population and practice setting, or discontinued.

Acceptance and Commitment Therapy for psychological and behavioural changes among parents of children with chronic health conditions: A systematic review

AIMS

To systematically identify the application of Acceptance and Commitment Therapy among parents of children with chronic health conditions and determine its effectiveness in parental psychological flexibility, psychological distress and parenting behaviour.

DESIGN

Systematic review.

DATA SOURCES

Nine databases (i.e. MEDLINE, PubMed, Embase, Cochrane Library, CINAHL, PsychINFO, Web of Science, China National Knowledge Infrastructure and WanFang Data) were systematically searched from inception to October 2019.

REVIEW METHODS

Quality of studies was appraised by using the Joanna Briggs Institute critical appraisal checklist. Findings were synthesized narratively. This work was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement.

RESULTS

Eight studies involving 485 parents were included. Results indicated that Acceptance and Commitment Therapy significantly improved parental psychological flexibility and reduced psychological distress compared with usual care and waitlist, but was not significantly different from active treatments. Limited studies have provided very preliminary evidence that Acceptance and Commitment Therapy can significantly improve dysfunctional parenting behaviour than usual care and waitlist. High attrition rate at follow-up made the overall confidence of maintained effect relatively low.

CONCLUSION

This review provides preliminary evidence that Acceptance and Commitment Therapy is beneficial for improving psychological flexibility, psychological distress and parenting behaviour among parents of children with chronic health conditions. Future studies with rigorous designs and large sample sizes are warranted to verify the evidence and explore its long-term efficacy.

IMPACT

Acceptance and Commitment Therapy has been increasingly applied to parents of children with chronic health conditions. This review provides positive evidence of its effects on psychological and behavioural outcomes among these parents. This work will help healthcare professionals and researchers with their practice and further research.

Effects of Acceptance and Commitment Therapy and Repetitive Transcranial Magnetic Stimulation on Obsessive-Compulsive Disorder

Objective: This study aims to explore the difference of clinical efficacy and psychological flexibility of sertraline hydrochloride combined with acceptance and commitment therapy (ACT) or repeated transcranial magnetic stimulation (rTMS) in patients with obsessive-compulsive disorder (OCD). Materials and Methods: Sixty-three inpatients diagnosed with OCD were randomly divided into ACT group (N = 32) and rTMS group (N = 31), both of which were combined with sertraline hydrochloride. The following assessments were completed by the Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Symptom Checklist 90 (SCL-90), Acceptance and Action Questionnaire (AAQ-II), and Cognitive Fusion Questionnaire (CFQ) during pretreatment, 4 weeks posttreatment, and 8-week follow-up. Results: After treatment: (1) the SCL-90 score of two groups significantly decreased from pretreatment to 8-week follow-up (P < 0.01 and P < 0.001); (2) The HAMA, HAMD, and Y-BOCS scores of the two groups significantly decreased from pretreatment to 8-week follow-up (P < 0.001 and P < 0.05); (3) No statistically significant difference of the SCL-90, HAMA, HAMD and Y-BOCS between two groups; (4) The AAQ-II and CFQ scores of the ACT group significantly decreased from 4 weeks posttreatment to 8-week follow-up (P < 0.01). However, no statistically significant difference was observed in the rTMS group (P > 0.05). Conclusions: Overall, our study suggested that sertraline hydrochloride combined with ACT or rTMS can improve the obsessive-compulsive symptoms, anxiety, and depression and has equivalent efficacy. Moreover, ACT can more effectively and durably improve the psychological flexibility of patients compared with rTMS.

CBT at the Crossroads: The Rise of Transdiagnostic Treatments

Transdiagnostic treatments span a heterogeneous group of interventions that target a wider range of disorders and can be applied to treat several disorders simultaneously. Several meta-analyses have highlighted the evidence base of these novel therapies. However, these meta-analyses adopt different definitions of transdiagnostic treatments, and the growing field of transdiagnostic therapies has become increasingly difficult to grasp. The current narrative review proposes a distinction of “one size fits all” unified and “my size fits me” individualized approaches within transdiagnostic therapies. Unified treatments are applied as “broadband” interventions to a range of disorders without tailoring to the individual, while individualized treatments are tailored to the specific problem presentation of the individual, e.g., by selecting modules within modular treatments. The underlying theoretical foundation and relevant empirical evidence for these different transdiagnostic approaches are examined. Advantages and limitations of the transdiagnostic treatments as well as future developments are discussed.

Health Anxiety and Mental Health Outcome During COVID-19 Lockdown in Italy: The Mediating and Moderating Roles of Psychological Flexibility

The COVID-19 emergency has severely affected the Italian population. During a pandemic, those with high health anxiety are at risk of adverse mental health outcomes, including peritraumatic distress and mood disturbance. No prior research has explored the role of psychological flexibility in protecting people at high risk of poorer mental health impacts due to health anxiety during a pandemic. Psychological flexibility is the cornerstone of psychological health and resiliency. According to acceptance and commitment therapy (ACT), it involves behaving consistently with one's chosen values even in the presence of emotional and mental discomfort. This study examined the mediating and moderating roles of psychological flexibility in the link between trait health anxiety and three mental health outcomes: COVID-19 peritraumatic distress, anxiety, and depression. We hypothesized that higher psychological flexibility would decrease the negative impacts of trait health anxiety on mental health outcomes. During the mandatory national lockdown (M = 35.70 days, SD = 8.41), 944 Italian adults (75.5% female, M = 38.86 years, SD = 13.20) completed an online survey consisting of standardized measures of psychological flexibility, trait health anxiety, COVID-19 distress, anxiety, and depression. Results indicated that psychological flexibility did not moderate the link between trait health anxiety and mental health outcomes. Rather, greater psychological flexibility mediated decreases in the adverse effects of trait health anxiety on COVID-19 distress, anxiety, and depression. In particular, two psychological flexibility processes, observing unhelpful thoughts rather than taking them literally (defusion) and values-based action (committed action), mediated decreases in the negative effects of trait health anxiety on all mental health outcomes. In contrast, the psychological flexibility process acceptance, which involves openness to inner discomfort, mediated increases in negative mental health outcomes. Overall, the combination of these processes mitigated the detrimental impacts of trait health anxiety on mental health during the emergency mandatory COVID-19 nationwide lockdown. Consistent with the ACT conceptualization of psychological flexibility, findings suggest embracing (rather than avoiding) inner discomfort and observing associated unhelpful thoughts, while also engaging in values-based action, increases resilience during adversity. Evidenced-based large-scale online public health interventions that target psychological flexibility in those experiencing health anxiety in the context of a pandemic are urgently needed. Many empirically-based ACT interventions are suited for this purpose.

Effectiveness of acceptance and commitment therapy (ACT) on depression and sleep quality in painful diabetic neuropathy: a randomized clinical trial

Background

Neuropathic pain is a complicated phenomenon in patients with diabetes. These patients have many problems, especially depression and Sleep disturbance. This study aimed to assess the effectiveness of Acceptance and Commitment Therapy on depression and Sleep disturbance in patients with painful diabetic neuropathy.

Methods

The current paper was conducted according to the clinical trial method with 50 participants. Participants were separated into intervention and control groups randomly. Based on the diagnosis of neurologists, all participants received standard medications to regulate neuropathic pain. The intervention group received ACT for eight sessions. The results were evaluated in the pre-test, post-test, and follow-up. The tools used were the Pittsburgh sleep quality index (PSQI) and Beck's depression inventory. Statistical analysis includes descriptive statistics, and repeated-measures (ANOVA) conducted by SPSS (version 26) software. Results: Results showed that in the intervention group, the treatment led to improved depressive symptoms (F = 6.81, P < 0.05). Besides, for sleep quality, treatment in all subscales, except for the Hypnotic medicine subscale, significantly improved the intervention group's situations. It was also observed that the overall quality of sleep in the ACT group showed a more significant improvement (P < 0.05). All the above results remained the same until the end of the follow-up period (P < 0.05).

Conclusion

ACT, as a complementary treatment, can improve the psychiatric symptoms and problems in people with neuropathic pain. Therefore, it is necessary to include psychotherapy services along with medical treatment in outpatient and hospitalization units.

Cognitive flexibility in critical CHD: a target for intervention

Most children born with even the most critical forms of CHD are now surviving well into adulthood. However, with increased survival has come increased recognition of the diverse neurobehavioural and psychosocial challenges these children experience. Among these challenges are deficits in executive function skills, including inhibitory control, working memory, and cognitive flexibility. Over the past several years, whereas inhibitory control and working memory deficits have garnered particular attention among clinicians and interventionists, relatively less attention has been paid to cognitive flexibility. This is unfortunate given both the high prevalence of cognitive flexibility deficits observed in children and adolescents with critical CHD, and also the far-reaching relevance of cognitive flexibility in helping individuals achieve optimal quality of life across the lifespan. This paper reviews the construct of cognitive flexibility, including its definition, development, measurement, and neuroanatomical basis, provides a summary of how cognitive flexibility is affected by CHD, and offers evidence-based recommendations to systematically support the development of cognitive flexibility within the context of CHD.
