The impact of treatment components suggested by the psychological flexibility model: a meta-analysis of laboratory-based component studies

Investigating Determinants of Client Psychotherapy Preference: An Analog Study

Increased emphasis has been placed on elucidating the contribution of client variables, such as treatment preference, to optimize evidence-based practice. This analog study sought to better understand variables associated with treatment preference using a convenience sample of college students (n = 54) who read brief descriptions of three interventions for negative thoughts-defusion, noticing, and restructuring. They rated each on acceptability and practicality and completed measures of cognitive fusion, emotional distress, and experiential avoidance as possible moderating variables. Restructuring was overwhelmingly preferred and rated as more acceptable than the two alternatives by both the overall sample and a distressed subsample. Preference for defusion or noticing was not predicted by ratings of acceptability or practicality but by elevated levels of cognitive fusion and emotional distress consistent with a compensation model. Limitations of the study and its implications for further research on psychotherapy preference and its integration within evidence-based practice are discussed.

A brief nonattachment intervention based on the three marks of existence: development, rationale, and initial evidence

BACKGROUND

The practices described in Buddhist philosophy are essentially a suite of non-theistic cognitive and behavioral interventions designed to induce nonattachment (N-A), which can be defined in terms of the absence of a need for one's personal reality to be other than it is. Although meditative practices have received attention in multiple literatures, the cognitive analogs to these behaviorally-oriented practices have not.

DESIGN

Two experiments involving undergraduate participants (total N = 239; M age = 19.04) investigated whether the provision of wisdom related to the Three Marks of Existence (i.e., some degree of suffering is inevitable, there is impermanence, and many events are not in our control) could result in (1) higher nonattachment attitudes, (2) lower threat appraisals, (3) lower stressor reactivity, and (4) shorter emotion reaction durations.

RESULTS

With moderate to large effect sizes, the Three Marks trainings (relative to placebo or control conditions) resulted in (1) higher nonattachment attitudes, (2) lower threat appraisals, (3) no differences in negative emotional intensity, but 4) shorter emotion durations.

CONCLUSIONS

These results provide preliminary evidence that enduring cognitive trainings such as the Three Marks can be an effective tool to increase acceptance-related attitudes while attenuating negative reactivity.

Effect of Psychotherapy on Intolerance of Uncertainty: A Systematic Review and Meta-Analysis

Intolerance of uncertainty (IU) is the tendency to react negatively on affective, cognitive and behavioural levels to uncertain situations and to harbour negative beliefs about the implications of uncertainty. IU has been linked to psychopathology and shown to impact treatment outcomes. This study systematically reviewed the literature and performed a meta-analysis of the effects of psychotherapy on IU. A total of 22 studies (1491 participants) were identified in online searches and included in the meta-analyses. Analyses were performed on studies with passive and active control conditions. The pooled effect on IU from studies with passive control was large (g = -0.94 [95% CI -1.25 to -0.62]) but with significant heterogeneity. Pooled effects on IU from studies with active controls were not significant. Moderator analysis showed that among studies with a passive control condition, studies that recruited participants from clinical care facilities produced smaller effect sizes. Among studies with an active control condition, study quality significantly moderated the results, with higher quality leading to a larger effect size. These results indicate that changes in IU may be difficult to reliably achieve in psychotherapy and leave many questions about the effect of psychotherapy on IU unanswered, such as what active components produced the observed changes in studies with passive control.

Individual and Organizational Ductility: Conceptualization, Development, and Validation of a New Scale

In this article, we conceptualize a new construct named "ductility" and propose a measurement instrument. We examine psychometric properties-the factorial validity and reliability of the Ductility Scale in Italy. The results of exploratory factor analysis showed that the scale has a two-factor structure, namely, individual and organizational ductility. The scale reliability was excellent for both dimensions (individual ω = 0.82; organizational ω = 0.85). The participants were employees from private and public organizations (n = 466). We tested the construct validity of the Ductility Scale. The invariance of the measurement model tested via multigroup confirmative factor analysis showed that the Ductility Scale was invariant across gender. In addition, we found ductility to be positively related to proactive personality and work engagement. These preliminary results show that the Ductility Scale is a reliable and valid measure. In addition, our findings illustrate the potential usefulness of the ductility construct via the newly developed scale.

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.

Ultra-brief acceptance & commitment therapy for inpatients with psychosis - a single-case experimental design investigating processes of change

People with primary psychosis are among the most seen in inpatient psychiatry. Treatment guidelines recommend both pharmacological and psychological treatments. However, psychological treatments are not routinely offered in many settings. There is also a lack of research on psychological treatments for this vulnerable population in the inpatient setting. The first aim of the current study was to examine treatment effects of a brief form of Acceptance and Commitment Therapy on outcomes valued by the treatment recipients. The second aim was to explore hypothetical processes of change in relation to outcomes over time. Three people with primary psychosis were treated for two to four sessions. A replicated single-case experimental design with multiple baselines across subjects (Clinical Trials registration number ID NCT04704973) was employed to examine treatment effects. The Personal Questionnaire (PQ) was used as primary outcome, symptom believability and preoccupation as proposed processes of change. Data were analyzed using visual inspection, calculation of Tau-U values, and cross-lagged correlation. All participants improved significantly on PQ and the symptom preoccupation measure. Two improved significantly on the symptom believability measure. Cross-lagged correlation analyses showed no clear mediation. Change in proposed processes of change and primary outcome predominantly happened concomitantly, although patterns of results reflected individual differences.

How mood is affected by environment and upsetting events: The moderating role of psychological flexibility

OBJECTIVE

Patients suffering from psychological disorders report decreased quality of life and low mood. The relationship of these symptoms to daily upsetting events or environments, and in the context of active coping mechanisms is poorly understood. The present study thus investigates the association between mood, psychological flexibility, upsetting events, and environment in the daily life of outpatients.

METHOD

We investigated 80 outpatients at the beginning of treatment, using event sampling methodology (ESM). Patients' mood, occurrence of upsetting events, current environment, and psychological flexibility were sampled six times per day during a one-week intensive longitudinal examination. Data were analyzed using linear mixed models (LMMs).

RESULTS

Participants reported worse mood the more upsetting events they experienced. Further, participants reported better mood when in private environments (e.g., with friends), and worse mood when at the hospital, compared to being at home. Higher levels of psychological flexibility, however, were associated with better mood, irrespective of the occurrence of upsetting events or current environment.

CONCLUSION

Results suggest that mood is positively associated with psychological flexibility, not despite, but especially during the dynamic and context-specific challenges of daily life. Psychological flexibility may thus potentially act as a buffer against distress-provoking situations as patients go about their daily lives.

Reduced attentional control in individuals with a history of suicide attempts compared to those with suicidal ideation: Results from a systematic review and meta-analysis

BACKGROUND

Neurocognitive profiles may be especially useful to identify factors that facilitate transitioning from contemplating suicide to attempting suicide. Generally, those who attempt suicide show greater disruptions in neurocognitive ability compared to those who think about suicide but do not proceed to attempt. The goal of this systematic review and meta-analysis is to test whether this pattern is observed with attentional control.

METHODS

We systematically searched PubMed, PsychINFO, CINAHL, and Google Scholar to find pertinent studies. All included studies compared attentional functioning using neutral stimuli. Each sample featured adults with a history of suicidal ideation (SI) and no history of suicide attempts (SA) compared to those with a history of SA.

RESULTS

We identified 15 studies with 32 effect sizes (N = 931; n = 506 with SI only; n = 425 with SA). SA groups, compared to SI groups, exhibited worse accuracy yet similar reaction time, suggesting a comparatively blunted speed-accuracy tradeoff. Relative to SI, SA groups performed worse on Stroop-like and Go/NoGo tasks. SA performed better than SI on Trail Making Test B, but not A.

LIMITATIONS

There were few available studies. Most samples were small. We did not differentiate current vs. past SI or high vs. low lethality SA. Only English and Spanish language articles were included.

CONCLUSIONS

Disrupted attentional control may convey risk for transitioning to SA from SI. More work is needed to determine which components of attention are most associated with suicide risk.

Psychological flexibility, birth satisfaction and postnatal trauma symptoms in women with abnormally invasive placenta

BACKGROUND

Abnormally Invasive Placenta is an obstetric condition resulting in significant physical complications and shown to increase the likelihood of developing Post Traumatic Stress Disorder. Dissatisfaction with the care experienced increases the likelihood of Post Traumatic Stress Disorder. Psychological flexibility has been shown to reduce the severity of Post Traumatic Stress Disorder, but there is no research regarding either of these in women with Abnormally Invasive Placenta.

AIM

To investigate if there is a relationship between trauma experience in women with a diagnosis of Abnormally Invasive Placenta, psychological flexibility, and birth satisfaction.

METHOD

Using a retrospective questionnaire, 126 participants age range 18-45, comprising the Birth Satisfaction Scale Revised Indicator (BSS-RI), Impact of Events Scale Revised (IES-R) and Acceptance and Action Questionnaire (AAQ-2) was completed. A hierarchical regression assessed the predictive relationship of Psychological Flexibility and Birth Satisfaction on Trauma symptoms.

RESULTS

The relationship between Birth Satisfaction measured using the BSS-RI and likelihood of Post Traumatic Stress Disorder (IES-R) was not supported (r (124) = -.08, p = .36). Results did show that Psychological Flexibility (AAQ-2) correlated with Trauma Score (IES-R) (r (124) = .68, p < .001) in women who had experienced Abnormally Invasive Placenta and explained 45.3% of the variance.

CONCLUSION

The results suggest that Post Traumatic Stress Disorder in those with Abnormally Invasive Placenta is as high as 1 in 2 and can be mediated by psychological flexibility. In turn, this suggests that interventions to increase Psychological Flexibility in those with the diagnosis may reduce trauma symptom severity.Abbreviations: AAQ-2 - Acceptance and Action QuestionnaireAIP - Abnormally Invasive PlacentaBAME - Black Asian or other Minority EthnicitiesBSS-RI Birth Satisfaction Scale Revised IndicatorEPH - EPH Gestosis (Pre eclampsia/Eclampsia)DSM - Diagnostic Statical ManualIES-R - Impact of Events Scale RevisedPAS - Placenta Accreta SpectrumPTSD - Post Traumatic Stress Disorder.

Acceptance and commitment therapy for psychosis: Current status, lingering questions and future directions

PURPOSE

Acceptance and Commitment Therapy for psychosis (ACTp) is a contextual behavioural intervention that promotes psychological flexibility by fostering active acceptance, cognitive defusion, values construction and committed action to enhance well-being and recovery. Multiple studies have shown that ACTp is acceptable and efficacious, but questions remain as to its distinction from similar approaches and the conditions under which it would be implemented most effectively.

METHODS

We present the current evidence for processes and outcomes of ACTp and summarise the qualitative findings of experiences of service users in ACT programmes. We compare ACTp with other cognitive behavioural therapies and mindfulness-informed interventions for psychosis.

RESULTS

Acceptance and commitment therapy for psychosis is promising as a pragmatic, process-driven intervention model. Further efforts are needed to investigate psychological flexibility in the context of psychosis with observational, experimental and intervention studies that will inform model scope and treatment refinement. Additionally, implementation research is the necessary next step, including how support persons can be trained in ACTp. Lower intensity and technology-assisted approaches have the potential to reduce barriers to accessing ACTp and extend impact.

CONCLUSIONS

Over the last 20 years, ACTp has demonstrated meaningful effects in individual and group formats in a range of settings, targeting outcomes such as rehospitalisation, depression, psychotic symptom distress and impact. Future work should focus on how best to integrate ACTp with other current evidence-based interventions for psychosis.

Flexibility and inflexibility in an Iranian sample: psychometric properties of MPFI based on the Hexaflex model

OBJECTIVES

Acceptance and Commitment Therapy (ACT) emphasizes the importance of psychological flexibility in promoting emotional, psychological, and social well-being, while also acknowledging rigidity as a precursor to psychological disorders. Analyzing the psychometric qualities based on the multidimensional Hexaflex model is critical for determining the efficiency of therapeutic interventions. Thus, the purpose of this study is to investigate the psychometric features of the Multidimensional Psychological Flexibility Inventory (MPFI) within the context of the Hexaflex model in a group of Iranian university students.

METHODS

Exploratory and confirmatory factor analyses were used in this study to evaluate the psychometric features of the flexibility/inflexibility scale (MPFI) in a sample of Iranian university students.

FINDINGS

In the exploratory factor analysis involving a sample of 300 students, six factors were identified for flexibility and six for inflexibility (56.3% males and 43.7% females). In the confirmatory factor analysis with a sample of 388 participants, the results validated 60 items across a total of six flexibility and inflexibility factors. This outcome can serve as a robust estimate for flexibility, inflexibility, the second-order model, and the final model. Cronbach's alpha values for various components, including acceptance, present-moment awareness (or contact with the present moment), self as context, cognitive defusing, values, committed action, total flexibility, experiential avoidance, lack of present-moment awareness, self as content, fusion, lack of contact with values, inaction, and total inflexibility, were reported as follows: 0.818, 0.869, 0.862, 0.904, 0.935, 0.935, 0.942, 0.895, 0.839, 0.883, 0.904, 0.912, 0.941, and 0.941, respectively.

CONCLUSIONS

The Farsi version of the MPFI for university students has great psychometric qualities, making it a reliable assessment instrument for the ACT.

Immediate, Short-term, Medium-term, and Long-term effects of Acceptance and Commitment Therapy for Smoking Cessation: A Systematic Review and Meta-Analysis

INTRODUCTION

Acceptance and commitment therapy (ACT) is increasingly being studied as a treatment for smoking cessation. However, its immediate, short-, and long-term effects have rarely been reviewed.

METHODS

This systematic review aimed to evaluate the effectiveness of immediate, short-, medium-, and long-term smoking cessation rates in ACT and comparators at less than 3-month, 3 to 4-month, 6-, and 12-month follow-ups. Randomized controlled trials (RCTs) were searched in eight databases until April 20, 2023. We assessed the quality of RCTs and the certainty of evidence of outcomes.

RESULTS

Nineteen RCTs involving 7885 smokers across six countries were included. The majority (72.81%) of RCTs were graded as low risk across six domains. For complete-case outcomes, meta-analyses were conducted, and the results revealed a significant effect in favor of ACT [risk ratio: 1.70-1.80 at <3-month, 3 to 4-month, and 6 months follow-up] compared with comparators. For outcomes using missing data management, meta-analyses found an overall effect in favor of ACT, but a significant effect was found at 3 to 4-months only. However, 12-month follow-ups revealed no significant reduction in smoking cessation for both outcomes. Moderate and substantial heterogeneities were found among four meta-analyses that may lead to inaccurate estimates of effects. The certainty of evidence of all outcomes was rated as low and very low.

CONCLUSION

ACT may be an effective intervention for smoking cessation with immediate, short-term, and medium-term effects. Caution must be applied in the interpretation of the results due to the limited trials and low certainty of evidence.

IMPLICATION

ACT can be implemented adjuvant to the usual treatment for smoking cessation. Additional RCTs with follow-up data using biochemically verified measures in non-US countries are warranted.

Wellness Achieved Through Changing Habits: A Randomized Controlled Trial of an Acceptance-Based Intervention for Adolescent Girls With Overweight or Obesity

Background: Obesity prevalence among adolescent girls continues to rise. Acceptance-based therapy (ABT) is effective for weight loss in adults and feasible and acceptable for weight loss among adolescents. This pilot randomized controlled trial (RCT) assessed effectiveness of an adolescent-tailored ABT intervention on decreasing weight-related outcomes and improving psychological outcomes compared with enhanced care. Methods: In this 6-month, two-arm pilot RCT, participants were randomized to the ABT intervention or to enhanced care. The ABT intervention condition attended 15 virtual, 90-minute group sessions. The enhanced care comparison received 15 healthy lifestyle handouts and virtually met twice with a registered dietitian. The primary outcome assessed was change in BMI expressed as a percentage of the 95th percentile (%BMIp95). Results: Participants included 40 girls (ages 14-19) assigned to ABT (n = 20) or enhanced care (n = 20). A decrease in %BMIp95 was observed within the ABT intervention [d = -0.19, 95% confidence interval, CI: (-0.36 to -0.02)], however, not within the enhanced care comparison [d = -0.01, 95% CI: (-0.09 to 0.07)]. The ABT group showed slight changes in psychological flexibility [d = -0.34, 95% CI: (-0.62 to -0.06)] over enhanced care [d = -0.11, 95% CI: (-0.58 to 0.37)]. There was no significant intervention effect noted between groups. Conclusion: In this pilot RCT, the ABT intervention was as effective as enhanced care for weight loss. However, previous ABT studies occurred in person, and this study was conducted virtually due to COVID-19. Thus, future research investigating the potential effectiveness of ABT in-person among adolescents and optimization of virtual interventions is needed.

The Idionomic Future of Cognitive Behavioral Therapy: What Stands Out From Criticisms of ACT Development

The present special section critical of Acceptance and Commitment Therapy or Training (ACT in either case) and its basis in psychological flexibility, relational frame theory, functional contextualism, and contextual behavioral science (CBS) contains both worthwhile criticisms and fundamental misunderstandings. Noting the important historical role that behavior analysis has played in the cognitive behavioral therapy (CBT) tradition, we argue that CBS as a modern face of behavior analytic thinking has a potentially important positive role to play in CBT going forward. We clarify functional contextualism and its link to ethical behavior, attempting to clear up misunderstandings that could seriously undermine genuine scientific conversations. We then examine the limits of using syndromes and protocols as a basis for further developing models and methods; the role of measurement and processes of change in driving progress toward more personalized interventions; how pragmatically useful concepts can help basic science inform practice; how both small- and large-scale studies can contribute to scientific progress; and how all these strands can be pulled together to benefit humanity. In each area, we argue that further progress will require major modifications in our traditional approaches to such areas as psychometrics, the conduct of randomized trials, the analysis of findings using traditional normative statistics, and the use of data from diverse cultures and marginalized populations. There have been multiple generational shifts in our field's history, and a similar shift appears to be taking place once again.

The use of Acceptance and Commitment Therapy (ACT) in informal caregivers of people with dementia and other long-term or chronic conditions: A systematic review and conceptual integration

Informal caregivers are the primary source of support for adults with chronic conditions and disabilities. Empirical research highlights chronic stress and other risks of adverse outcomes of caregiving. Acceptance and Commitment Therapy (ACT) is an emerging evidenced-based practice that shows promise in improving an array of outcomes, theoretically by increasing psychological flexibility as the primary process of change. Research has begun to evaluate ACT among informal caregivers of adult populations, and a systematic review is now needed to summarise this evidence base. Electronic searches from five databases, including PubMed, PsycInfo, Embase, CINAHL, and Cochrane Library, yielded an initial 7896 hits, which after screening for inclusion criteria, resulted in 21 clinical trials. Studies were coded to synthesise the feasibility, effectiveness, and quality of evidence. Findings show that ACT was reported to be largely feasible and acceptable. However, the efficacy of ACT was mixed, with a more consistent pattern for informal caregivers of people with dementia. Several methodological quality issues limited the findings. However, theoretical synthesis and preliminary evidence support the promising effect of ACT in subgroups of informal caregivers. Research on the process of change, as well as larger-scale, methodologically rigorous trials, are needed to consolidate these findings.

ACT: A Process-Based Therapy in Search of a Process

A large array of randomized controlled trials and meta-analyses have determined the efficacy of Acceptance and Commitment Therapy (ACT). However, determining that ACT works does not tell us how it works. This is especially important to understand given the current emphasis on Process-Based Therapy, the promise of which is to identify manipulable causal mediators of change in psychotherapy, and how their effectiveness is moderated by individual contexts. This paper outlines four key areas of concern regarding ACT's status as a Process-Based Therapy. First, the relationship between ACT and Relational Frame Theory has been widely asserted but not yet properly substantiated. Second, most of the studies on ACT's core process of change, psychological flexibility, have used invalid measures. Third, while lots of research indicates means by which individuals can be helped to behave consistently with their values, there is virtually no research on how to help people effectively clarify their values in the first instance, or indeed, on an iterative basis. Finally, the philosophy underlying ACT permits a-moral instrumentalism, presenting several ethical challenges. We end by making several recommendations for coherent methodological, conceptual, and practical progress within ACT research and therapy.

Toward a synthesis of cognitive behaviour therapy via component analysis of self-regulation

The cognitive behavioural therapies (CBTs) are the choice psychotherapies for many clinicians treating a wide range of adult psychological disorders including various anxieties, mood, substance use, eating, schizophrenia and personality-related. Empirical research in the CBTs is ever increasing, and the accumulating evidence supporting efficacious treatments is substantial and well documented. However, with prolific research comes a seemingly accelerating and worrying trend of purportedly different therapies, and numerous hybrids and combinations of therapies and techniques. For many clinicians this is increasingly confusing and not helpful in clinical practice. This article is a critique of current trends and directions in clinical research, which show signs of limited effectiveness, fragmentation, and obfuscation. An alternative strategy is proposed-examining transdiagnostic therapeutic effects, which appear related to treating pervasive dysregulated emotions, with component analyses of four principal self-regulation components (viz., self-monitoring; functional analysis; identifying values, goals and treatment-plans; and feedback). Such a strategy is likely to lead to a more coherently synthesized and effective CBT.

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.

Acceptance and commitment therapy processes and their association with distress in cancer: a systematic review and meta-analysis

Around 42% of individuals with cancer experience distress. Acceptance and commitment therapy (ACT) can reduce distress, but effects are small, and mechanisms unclear. This review aimed to identify associations between ACT processes and distress in cancer. Search terms included cancer, ACT processes, self-compassion, and distress. Six online databases and grey literature were searched until March 2022. Of 6555 papers screened, 108 studies were included with 17,195 participants. Five meta-analyses of 77 studies were conducted. Random effects meta-analyses of correlations revealed higher scores on flexible processes (acceptance, present moment awareness, self-compassion) were associated with lower distress (rpooled = -0.24, -0.39, -0.48, respectively); whilst higher scores on inflexible processes (experiential avoidance, cognitive fusion) were associated with higher distress (rpooled = 0.58, 0.57, respectively). Meta-analyses displayed moderate-to-high heterogeneity with most studies assessed as low risk of bias. Meta-regressions revealed no significant moderators (stage, time since diagnosis, gender and age). This review provides a theoretically aligned evidence base for associations between ACT processes and distress in cancer, supporting elements of ACT theory and providing targeted directions for intervention development. Due to limited evidence, future research should focus on self-as-context, values and committed action and conduct mediation analysis in controlled trials of ACT processes on distress in cancer.

A Network Analysis Approach on the Psychological Flexibility/Inflexibility Model

Acceptance and Commitment Therapy (ACT) is purported to work via targeting six interrelated processes summarized as the Psychological Inflexibility/Psychological Flexibility (PI/PF) model. However, the theoretical structure and interconnections of this model have not been sufficiently explored. Lacking are examinations of the interrelations among its components. Network Analysis (NA) can model PI/PF as a system of interconnected variables. We aimed at exploring the role and associations of the PI/PF model's components using NA in two different samples and sets of scales, and compare its structure across sub-samples. Sample 1 consisted of 501 individuals, who completed an online battery of questionnaires including the Multidimensional Psychological Flexibility Inventory, and Sample 2 consisted of 428 people, who completed an online set of six ACT measures, each assessing a component of the PI/PF model. NA could not verify the six ACT dimensions as distinct components. Values and Committed Action components were found to be strongly associated and combined in a group in both sets of measures and samples. Interestingly, Acceptance and Defusion were not the most central components as purported in some ACT conceptualizations, whereas Self-as-Context had a key role on both sets of measures and its items were often merged with Present Moment Awareness items. No significant differences were found in the comparison of networks across different subsamples and sets of scales. After combining different sets of scales, the six ACT components could not be completely verified as distinct entities, which might reflect problems with the theoretical model, or with the scales used. All components had critical roles in the model, particularly Self-as-Context, which reflects the need to redirect research towards this understudied construct. Findings point towards considerations of a triflex instead of a hexaflex ACT model.

Effectiveness of Mindfulness-acceptance-commitment based approach for Rumination, Cognitive Flexibility and Sports Performance of Elite Players of Beach Soccer: A Randomized Controlled Trial with 2-months Follow-up

Background/Objective

There is little research on the effectiveness of new approaches to psychology, including mindfulness-acceptance-commitment, especially in team disciplines. Therefore, this study compared mindfulness-acceptance and commitment-based approaches to rumination, cognitive flexibility, and sports performance of elite beach soccer players during a two-month follow-up.

Methods

The research design consisted of a randomized controlled trial (RCT), with follow-up. Thus, 34 players of the premier league of beach soccer were randomly divided into intervention and control groups based on mindfulness acceptance and commitment. The experimental group exercises consisted of one session per week for 7 weeks and daily homework. Participants filled out the questionnaires of the Ruminative Response Scale, Cognitive Flexibility Inventory, and Sports Performance Questionnaire before, after, and at two months of follow-up of the intervention.

Results

Multivariate Analysis of Variance (MANOVA) and Analysis of Variance (ANOVA) with repeated measures were used to evaluate the changes over time and compare the scores of the subjects of the two groups. The results showed a significant difference in mindfulness-acceptance and commitment intervention in the experimental group on pre- vs. post-test and pre-test vs. follow-up scores of research variables. Also, a comparison of groups using independent T-test analysis showed a significant effect of mindfulness-acceptance and commitment exercises on research variables in the experimental group in the post-test and follow-up stages.

Conclusion

Findings suggest that mindfulness, commitment, and acceptance exercises can be used as a new method to reduce rumination and increase cognitive flexibility and sports performance of elite beach soccer players.

Temperament, Life Satisfaction, and the Role of Psychological Flexibility

Abstract: Temperament is related to well-being. Establishing mediators of this relationship, especially mediators which can be influenced through psychological interventions, may contribute to tailoring these interventions to people’s needs determined by temperament. Psychological flexibility may be considered such a mediator. This study aims to examine the relationships between temperament traits and structures, satisfaction with life, and psychological flexibility, with the latter as a possible mediator of the relationship between temperament structures and life satisfaction. 538 participants (18–93 years old) took part in the study. They filled a set of self-reported questionnaires. Psychological flexibility explained a significant part of the variance in life satisfaction above and beyond temperament traits. People with harmonized temperament structures and higher stimulation processing capabilities (sanguine) exhibited higher psychological flexibility and satisfaction with life. Three temperament structures: phlegmatic, choleric, and melancholic in comparison to sanguine were found to be linked to lower satisfaction with life through lower psychological flexibility. The results suggest a meaningful role of stimulation processing capabilities in the development of both psychological flexibility and satisfaction with life.

Psychological flexibility in older adulthood: a scoping review

OBJECTIVES

Psychological flexibility/inflexibility (PF/PI) is a core component of the acceptance and commitment therapy (ACT) model, which is gaining more attention in the geropsychological literature. This scoping review examines the size and scope of the research on PF/PI in older adulthood related to age differences between older adult and younger samples, correlates relevant to psychological health, and changes with ACT.

METHODS

A systematic literature search was conducted using PubMed, CINAHL, and PsycINFO. Peer-reviewed articles available in English were included that: had a mean age ≥65 and a minimum age ≥60; and reported self-report measures of PF/PI. We categorized PF/PI into three domains: open, aware, and engaged.

RESULTS

Forty-six articles were included. Most studies measured open or aware domains; few measured the engaged domain. Older adults evidenced greater awareness compared to younger adults (9 of 13 analyses were significant). Openness and awareness consistently yielded medium to large correlations with anxiety and depression. PF/PI did not relate with positive affect and inconsistently correlated with quality of life measures.

CONCLUSION

Despite emerging trends, variability and limitations were evident in the literature. Specifically, measurement issues, lack of conceptual clarity, and the omission of values and behavioral measures require future attention.

Cross-Cultural Psychometric Analysis of the Mature Happiness Scale-Revised: Mature Happiness, Psychological Inflexibility, and the PERMA Model

The present study aimed to evaluate the psychometric properties of the Mature Happiness Scale, a measure focused on inner harmony. Mature happiness is achieved when a person can live in balance between both positive and negative aspects of their life. A total sample of 2,130 participants from five countries (Canada: n = 390, United States: n = 223, United Kingdom: n = 512, Spain: n = 724, and Hungary: n = 281) responded to an online survey including the original Mature Happiness Scale, the PERMA-Profiler, and the Acceptance and Action Questionnaire-II. Exploratory and confirmatory factor analyses yielded a one-factor solution with seven positive items (non-reversed). We called this new version of the questionnaire the Mature Happiness Scale-Revised (MHS-R). Measurement invariance was found across countries, age groups, gender, and mental disorder diagnosis. Internal consistency and test-retest reliability were high. Older people, males, and people without a mental disorder diagnosis scored higher in mature happiness than younger ones, females, and those with a mental health disorder diagnosis, respectively. Mature happiness showed strong positive associations with various subscales of the PERMA-Profiler, specifically with positive emotions and meaning in life. In addition, mature happiness was strongly correlated with less negative affect and inner conflict and lower psychological inflexibility, whereas it was moderately correlated with lower loneliness. This validity evidence supports the cross-cultural use of the MHS-R in the aforementioned countries to reliably measure happiness among adults. With its holistic approach, the MHS-R may be a unique complement to other well-being measures, particularly to better predict mental health problems.

Incremental Validity of Cognitive-Behavioral Therapy and Acceptance and Commitment Therapy Mechanisms for Anxiety and Panic Symptomology

Background: acceptance and commitment therapy (ACT) and cognitive-behavioral therapy (CBT) are empirically supported treatments for anxiety and panic disorder (PD), though they differ in their putative vulnerability and maintenance processes. The present study examined the incremental validity of several of these models' proposed core processes, including anxiety sensitivity (AS), dispositional avoidance, experiential avoidance (EA), cognitive fusion (CF), and mindfulness, as well as the interaction of the processes within each model, in the prediction of anxiety and panic symptomology. Methods: a sample of US adults (n = 316) completed self-report measures of AS, dispositional avoidance, EA, CF, mindfulness, anxiety, and PD symptoms. A series of hierarchical multiple regression analyses were conducted. Results: hierarchical regression analyses indicated that AS, dispositional avoidance, and EA predicted anxiety and panic symptoms even after controlling for one another, CF, mindfulness, and demographic variables. Although mindfulness and CF was correlated with anxiety and panic at the univariate level, they did not predict either outcome above and beyond AS, dispositional avoidance, and EA. When interaction terms were added to the models, the interaction between AS and -dispositional avoidance was a significant predictor of panic and anxiety symptoms, whereas the interaction between EA and CF only predicted panic symptoms. None of the interactions that included mindfulness were significant predictors. Conclusions: these findings provide support the independent and interactive predictive value of traditional CBT (AS, dispositional avoidance, and AS-dispositional avoidance) and ACT (EA) processes for anxiety and panic symptoms, but raise questions about the incremental predictive utility of CF and mindfulness.

The Relationship Between Psychological Flexibility and Depression, Anxiety and Stress: A Latent Profile Analysis

Purpose

To explore the potential classification of psychological flexibility (PF) among Chinese college students, analyze whether there is group heterogeneity in PF, and discuss the differences in the latent profile of PF in the negative emotions of depression, anxiety, and stress.

Methods

A total of 1769 college students were investigated using the Psychological Flexibility Questionnaire and Depression-Anxiety-Stress Self-rating Scale, and heterogeneity was tested by latent profile analysis.

Results

The PF of college students can be divided into three latent profiles: self-contradiction group (19.2%), high PF group (34.1%), and low PF group (46.7%). The scores of depression, anxiety, and stress are significantly different among the groups.

Conclusion

There is obvious group heterogeneity in the PF of college students, and they can be divided into the self-contradiction group, the high PF group, and the low PF group. The self-contradiction and low PF groups score significantly higher on the negative emotions of depression, anxiety, and stress than the high PF group.

Examining the roles of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout: A longitudinal study

OBJECTIVES

Athlete burnout is a maladaptive outcome that is potentially detrimental for performance and wellbeing. Cross-sectional evidence suggests that mindfulness might be associated with athlete burnout via experiential avoidance and cognitive fusion. In the current study, we extend knowledge of these hypothesized mediational pathways using a longitudinal design.

METHODS

Data was collected at three occasions with a three-month interval. A final sample of 280 elite Chinese athletes aged 15-32 years (Mage = 19.13; SD = 2.92; Female = 130) reported their mindfulness at Time 1, experiential avoidance and cognitive fusion at Time 2, and athlete burnout at Time 3. Structural equation modelling was adopted to examine the mediating roles of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout.

RESULTS

We found statistically meaningful directs effects from mindfulness (Time 1) to experiential avoidance and cognitive fusion (Time 2), which in turn influenced athlete burnout (Time 3). However, the direct effect from mindfulness at Time 1 to athlete burnout at Time 3 was non-significant. The indirect effects of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout were significant, providing longitudinal evidence that these two variables contribute meaningfully to the mindfulness-burnout pathway.

CONCLUSION

With initial evidence for the mediating effects of experiential avoidance and cognitive fusion, future studies could consider using experimental designs to examine the potential changing mechanisms of mindfulness on reducing athlete burnout.

Which outcome variables are associated with psychological inflexibility/flexibility for chronic pain patients? A three level meta-analysis

The psychological flexibility model can be seen as a basis for an integrated and progressive psychological approach to chronic pain management. Some researchers suggest that psychological flexibility and inflexibility represent distinct processes and constructs. This meta-analysis is the first to provide a summary estimate of the overall effect size for the relationship between psychological (in)flexibility and common outcomes among chronic pain patients. The research protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO, https://www.crd.york.ac.uk/PROSPERO/), registration number CRD42021285705. Four databases were searched (PsycINFO; PubMed; Web of Science, CINAHL) along with reference lists. Thirty-six cross-sectional studies were included (7,779 participants). Meta-analyses (random effects model) indicated a significant medium negative association between psychological flexibility and pain intensity or functional impairment. The present study also indicated a significant small to medium association between psychological inflexibility and pain intensity, a nearly large association between psychological inflexibility and functional impairment as well as the quality of life, and a large association between psychological inflexibility and anxiety/depression. Due to the limited number of included studies, the relationship between risk behavior and psychological inflexibility may not be significant. Types of countries and instruments measuring psychological inflexibility may explain part of the heterogeneity. These findings may carry significant implications for chronic pain patients regarding the potential relationship between psychological inflexibility or flexibility and these outcomes. It may consequently form the basis for more robust testing of causal and manipulable relationships.

The impact of psychological flexibility on family dynamics amidst the COVID-19 pandemic: A longitudinal perspective

Background

Health risks associated with contracting COVID-19, stay-at-home orders, and pandemic-related economic and social hardships created unique challenges for individuals throughout the pandemic, and in particular for families whose daily routines were disrupted at the start of the pandemic. This study applied a contextual behavioral science lens to Family Systems Theory to examine the impact of COVID-19 stressors on family and individual functioning.

Methods

A sample of 742 coparents (86% married/engaged; 84% Caucasian; 71% female; M = 40.7 years old, SD = 8.1; M _income = $82,435, SD _income = $27,604) of school-aged children (5-18 years old) completed a baseline survey from late March to late April 2020. Of the initial sample, 556 coparents completed weekly diaries for 8 weeks.

Results

Mediation models were tested within a multilevel path modeling framework to evaluate both the stable, between-family differences (i.e., at level 2) and the within-family changes from week to week (i.e., at level 1). Across both levels of the model, parent psychological inflexibility was robustly linked to poorer functioning across all levels of the family system, showing direct links to a majority of the processes assessed. The results further supported a top-down spillover cascade in which parent inflexibility was proximally linked to greater COVID-19 related stress and parent depressive symptoms, which were proximally linked to poorer romantic functioning (greater negative conflict, lower satisfaction), which were proximally linked to poorer family functioning (greater coparent discord and family chaos), which were proximally linked to poorer parenting (greater angry/reactive parenting), which was proximally linked to greater child distress. Multi-group models suggested that the results were largely stable across (1) parent race (white vs non-white), (2) family size (1 child vs 2 or more), (3) child age (less than 10 years old vs 10 or older), (4) parent age (under 40 vs. 40 or older), (5) perceived COVID-19 risk, (6) parent gender (mothers vs fathers), (7) household income groups (less than $100k vs $100k or more), and (8) perceived economic stress/uncertainty (low vs high). However, a handful of moderated effects emerged from those multi-group models suggesting that fathers might be slightly more prone to negative spillover effects across the family systems and that wealthier families might have experienced the stress of new demands (e.g., homeschooling, remote working) as more disruptive.

Conclusions

Results highlight the crucial role parental psychological flexibility and inflexibility play in families managing the stress of COVID-19, as well as key mechanisms for how those stressors may either reverberate or become dampened throughout the family system.

The Iranian form of psychometric properties of the Multidimensional Psychological Flexibility Inventory

The Multidimensional Psychological Flexibility Inventory (MPFI) is a new 60-item self-report scale developed to assess the specific components of psychological flexibility and inflexibility proposed in the Hexaflex model of Acceptance and Commitment Therapy (ACT). The present study sought to examine the psychometric properties of the Persian version of the MPFI-60 in a community sample of 307 Iranian adults. The original study supported a 12-factor second-order structure consisting of 6 dimensions for psychological flexibility and 6 dimensions for psychological inflexibility. The Persian MPFI-60 demonstrated acceptable semantic and test content, internal structure, correlations with other variables, and internal consistency. It also evidenced in relation to anxiety, stress, depression, and self-compassion. Overall, the results indicate that the Persian MPFI-60 is a psychometrically sound measure in the Iranian context that enables researchers and clinicians to comprehensively assess the components of psychological flexibility and inflexibility within the Hexaflex model.

Prevalence and predictors of mental health outcomes in UK doctors and final year medical students during the COVID-19 pandemic

BACKGROUND

The mental health of doctors is an ongoing concern, both prior to and during the COVID-19 pandemic. This study aimed to: i) assess the prevalence of symptoms of depression, anxiety, PTSD, and burnout in UK doctors and final year medical students during the pandemic, and ii) analyse the hypothesised relationships between psychological flexibility, intolerance of uncertainty and resilience with these mental health outcomes.

METHODS

A cross-sectional online study of UK-based doctors and final year medical students was conducted between 27/09/2020 and 31/01/2021. Outcomes were measured using the PHQ9, GAD7, PCL-5, and aMBI. Independent variables included the CompACT-SF, IUS-12, and CD-RISC-10. Descriptive statistics, between-group analyses, and multiple regression were performed.

RESULTS

Prevalence of anxiety symptoms was 26.3%, depression 21.9%, PTSD 11.8%, and burnout 10.8%. Psychological flexibility negatively predicted all outcomes, apart from low personal achievement. Intolerance of uncertainty positively predicted anxiety and PTSD scores. Resilience negatively predicted scores on burnout subscales.

LIMITATIONS

Cross-sectional design and non-probability sampling method means that assumptions about causality cannot be made and may have implications for bias and generalisability of results.

CONCLUSION

Doctors and medical students in the UK reported high levels of mental health symptoms during the pandemic, between September 2020 and January 2021. All three independent variables explained significant variance in mental health outcomes. Psychological flexibility was the most consistent predictor, over and above sociodemographic variables and other psychological predictors. These findings have implications for interventions to improve retention of our essential medical workforce, and for providing support at future times of national crisis.

Incremental validity of acceptance over coping in predicting adjustment to endometriosis

Psychological acceptance has emerged as an important construct to explain low psychological distress in different clinical samples. However, the incremental validity of psychological acceptance to explain adjustment to medical conditions over other related and well-established constructs, such as coping, is relatively unclear. This study explored whether psychological acceptance significantly contributes to explain adjustment above and beyond coping in females with endometriosis. A total of 169 females (M_age = 34.95 years; SD_age = 6.07 years) with endometriosis and pain symptoms completed the Acceptance and Action Questionnaire-II, the Brief-COPE, the Hospital Anxiety and Depression Scale, the Psychological Wellbeing Scale, and the Endometriosis Health Profile-5. We conducted Hierarchical Regression Analyses to determine the contribution of psychological acceptance to explaining adjustment. The results showed that the contribution of psychological acceptance ranged from 11 to 20% when controlling for coping, while coping explained from 1 to 8% when the model was reversed. The findings suggest that psychological acceptance is a more useful construct than coping for predicting PD and other psychological outcomes in females with endometriosis.

The Applicability of Acceptance and Commitment Therapy for Obsessive-Compulsive Disorder: A Systematic Review and Meta-Analysis

Background: Acceptance and commitment therapy (ACT), a third-generation cognitive behavioral therapy (CBT), has proved its efficacy amidst various mental disorders. A growing body of studies has shown that ACT can improve obsessive-compulsive disorder (OCD) severity in recent years. To assess the effect of ACT on OCD, we carried out a systematic review and meta-analysis to provide a basis for therapists to use different psychological dimensions of ACT for OCD. Methods: PubMed, the Cochrane Library, EMBASE, EBSCO Host, and literature references were searched until May 2021. Randomized controlled trials (RCTs) and other study designs assessing the effect of ACT among adults suffering from OCD were examined. Results: Fourteen studies, including 413 participants, published between 2010 and 2021 were identified. ACT made statistically significant progress in the Yale–Brown Obsessive–Compulsive Scale (YBOCS) compared with control conditions. Conclusion: After reviewing all the ACT studies, we acknowledge the plausibility of ACT in treating OCD and improving its symptoms for the clinical population. ACT can also be an adjunct therapy for other well-established treatments. It also favors targeting psychological inflexibility. Further well-controlled and high-quality RCTs are required for a better conclusion in further studies.

New generation psychological treatments in chronic pain

Chronic pain conditions are common and have a considerable impact on health and wellbeing. This impact can be reduced by cognitive behavioral therapy (CBT), the most commonly applied psychological approach to chronic pain. At the same time, CBT continues to develop, and now includes what is sometimes called "third wave" CBT. In this review, we examine the evidence for application of acceptance and commitment therapy (ACT), a principal example of this new wave or latest generation of treatment approaches, in people with chronic pain. We identified 25 randomized controlled trials of ACT for adults with chronic pain. Across the included trials, small to large effect sizes favoring ACT were reported for key outcomes including pain interference, disability, depression, and quality of life. Evidence from three studies provided some support for the cost effectiveness of ACT for chronic pain. Evidence also supported the mediating role of theoretically consistent processes of change (psychological flexibility) in relation to treatment outcomes. Investigation of moderators and predictors of outcomes was limited and inconsistent. In future, a greater focus on process based treatments is recommended. This should include continued identification of evidence based processes of change, and research methods more suited to understanding the experience and needs of individual people.

Study design and protocol for tailored Acceptance and Commitment Therapy (ACT) to optimize quality of life in women living with metastatic breast cancer

Women living with metastatic (stage IV) breast cancer face unique challenges, including arduous treatments, side effects, chronic symptom burden, and emotional distress. Nevertheless, most research has paradoxically focused on optimizing quality of life in women with early-stage, non-metastatic breast cancer. Acceptance and Commitment Therapy (ACT) is an evidence-based, third-wave cognitive behavioral therapy that focuses on creating 'a life worth living' by promoting meaning and purpose and optimizing quality of life. ACT may be particularly well-suited for women with metastatic breast cancer as it addresses salient existential concerns, while allowing for the co-occurrence of feelings of grief and loss that are normal and expected when facing a life-limiting prognosis. This manuscript describes the rationale and study design of a pilot randomized controlled trial to develop and assess the feasibility and acceptability of a tailored ACT intervention for women living with metastatic breast cancer. Participants (N = 30) will be randomized 1:1 to either ACT, cognitive behavioral stress management (CBSM), or a usual care control. Both ACT and CBSM are 8-week, group-based interventions that will be delivered online. Primary outcomes are rates of acceptance, retention, and satisfaction. Preliminary effects on variables of interest, including meaning and purpose, psychological flexibility, and several domains of quality of life, will also be examined. Findings will inform the conduct of a full-scale randomized controlled trial of our tailored ACT intervention in women living with metastatic breast cancer.

Associations Between Six Core Processes of Psychological Flexibility and Functioning for Chronic Pain Patients: A Three-Level Meta-Analysis

The previous research showed contradictions in the relationships between psychological flexibility processes and functioning. This meta-analysis is the first to provide a comprehensive meta-analysis of the associations between six core processes of psychological flexibility and functioning among chronic pain patients. Four databases were searched (PsycINFO; PubMed; CINAHL; Web of Science) along with reference lists. Thirty-six cross-sectional studies were included (7,812 chronic pain patients). A three-level meta-analytic model was used to examine the associations. The publication bias was assessed with the Egger test, funnel plot, and p-curve analysis. Significant associations were found between functioning and six processes of psychological flexibility (i.e., acceptance, defusion, present moment, committed action, self as context, and values). Except for the relationship between defusion and functioning, the relationships between the other five psychological flexibility processes and functioning were all moderated by domains of functioning. No moderators were found regarding age, percentage of females, country, or type of instrument used to measure functioning. These findings may carry significant implications for chronic pain patients and clinical workers. It might be more effective to focus on functioning-related psychological flexibility processes rather than all therapy packages if the relationships between functioning and specific processes of psychological flexibility were better informed. Limitations were also discussed.

Acceptance and Commitment Therapy for Patients with a First Psychotic Episode

The search for the most effective methods of therapy for mental disorders is a priority for modern psychiatry. An approach to the early diagnostics and rehabilitation of patients experiencing psychotic episodes for the first time is proposed in the present article. The proposed approach is based on the combination of drug therapy and acceptance and commitment therapy (ACT) characterized by the development of the patient's psychological flexibility, rather than controlling the disease symptoms. The article describes the main processes of the ACT model: acceptance, cognitive defusion, contact with the present moment, understanding of the inner world, awareness of significant values, and the regulation of purposeful behaviour for the implementation of these values. Recommendations for different stages of treatment were also developed by specialists of the First Psychotic Episode Clinic at the Mental Health Clinic No.1 named after N.A. Alexeev. The psychological rehabilitation of patients with the use of ACT in the case of psychotic disorders with both negative and positive symptoms was elaborated. The application of acceptance and commitment therapy in the early diagnostics and treatment of patients experiencing a first psychotic episode results in fewer readmissions and improved psychosocial functioning in both inpatient and outpatient care.

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.

Psychological flexibility, temperament, and perceived stress

BACKGROUND

Psychological flexibility (PF) is an ability to engage in meaningful actions regardless of the presence of difficult internal experiences. Higher psychological flexibility was found to be related not only to a lower level of the symptoms of psychopathology, but also with better functioning, lower stress levels and higher well-being. As temperament impacts preferred styles of action, data on the relationships between temperament, psychological flexibility and other criteria can provide ideas on how to improve the process of PF development. The aim of this study was to examine the relationships between psychological flexibility, temperament traits and perceived stress.

PARTICIPANTS AND PROCEDURE

A total of 254 people, aged 18-93, recruited directly by 13 pollsters from a local community sample, took part in the study. Temperamental traits were operationalized according to the regulative theory of temperament. Participants completed self-report measures.

RESULTS

Psychological flexibility was predicted by emotional reactivity and perseveration and it was a significant predictor of stress beyond and above temperamental traits. While the relationship between stress and two temperamental traits - emotional reactivity and perseveration - was partially mediated by psychological flexibility, activity was related to stress directly.

CONCLUSIONS

Psychological flexibility is determined by temperamental traits to some extent. Further research on psychological flexibility and temperament needs to take an empirical design and test possible reciprocal effects.
