Investigating an Acceptance and Commitment Therapy-Based Exposure Therapy Intervention in Treatment-Refractory OCD and Related Disorders: Changes in Psychological Flexibility, Treatment Engagement, and Treatment Perceptions

While exposure therapy is the most effective psychological treatment for obsessive-compulsive disorder (OCD), anxiety, and traumatic stress-related disorders, it is not universally effective, indicating a need for further treatment optimization. This study investigated a shift in approach to exposure therapy with 29 treatment-refractory adults in an OCD clinic not responding to standard treatment, comprising habituation-based exposure therapy. Participants completed a standard exposure as a continuation of standard clinic treatment, followed by an acceptance and commitment therapy (ACT) consultation session to assess psychological inflexibility processes interfering with treatment progress, and then an ACT-based exposure targeting behavior change through increasing psychological flexibility. After each exposure, participants and independent raters reported levels of psychological flexibility, rituals, distress, treatment engagement, and treatment perceptions. We observed that the shift to ACT-based exposure was associated with greater psychological flexibility, treatment engagement, treatment acceptability, and treatment preference. These findings suggest that there may be situations where ACT-based exposure has particular utility.

Pain Catastrophizing Related to Psychological Inflexibility, Self-Reported Injuries and Perfectionism in Soccer Referees

Abstract Purpose This study aimed to analyze how psychological flexibility, perfectionism, and reported injuries are related to pain catastrophizing in soccer referees. Methods Design: This was a descriptive cross-sectional study. Setting: Data were collected online from 199 soccer referees. Pain catastrophizing was assessed with the Pain Catastrophizing Scale, psychological inflexibility with the Acceptance and Action Questionnaire, and perfectionism with the Frost Multidimensional Perfectionism Scale. Data were also gathered on other injury-related variables. Results Referees with medium–high scores on psychological inflexibility showed greater pain catastrophizing (t = 5.322, P < 0.001), rumination (t = 4.004, P < 0.001), helplessness (t = 5.023, P < 0.001) and magnification (t = 5.590, P < 0.001) than those with low scores. Psychological inflexibility emerged as a significant predictor of catastrophizing (β = 0.313, P = 0.006). A slight relationship was found between perfectionism and catastrophizing. For all subscales, the referees who reported mild–moderate injuries in the last three seasons showed greater pain catastrophizing, while those with severe injuries obtained higher scores on all dimensions of catastrophizing except magnification. Finally, those who reported severe injuries only obtained higher scores on rumination and helplessness. Conclusion These results provide a better understanding of the variables that influence pain perception. Possible interventions are suggested based on the observation that greater psychological flexibility was associated with lower pain catastrophizing, with the specific features of the latter depending on the presence and severity of the injury.

The CompACT-10: Development and validation of a Comprehensive assessment of Acceptance and Commitment Therapy processes short-form in representative UK samples

The Comprehensive assessment of Acceptance and Commitment Therapy Processes (CompACT) has frequently been deployed within contextual behavioural research and shown to reliably measure psychological flexibility. However, at 23 items, the scale is relatively long and burdensome, limiting suitability for some measurement contexts, assessment schedules, and respondent groups. Although abbreviated versions of the CompACT have been proposed within the literature, these have arisen from efforts to improve the psychometric properties of the original scale (e.g., removing less stable items) versus any a priori goal of developing a short-form scale. In this study, we describe the development of a psychometrically robust short-form of the CompACT (CompACT-10), and explore and confirm the measure's factor structure, stability, validity, and reliability in two moderately large, independent, UK-representative samples (Ns = 401 and 399). The CompACT-10 demonstrated acceptable internal consistency, for both full- and sub-scale indices, and converged and diverged in theory-consistent ways with other measured variables; higher CompACT-10 scores (indicating greater psychological flexibility) were associated with lower psychological distress and greater levels of health and wellbeing. Confirmatory Factor Analysis of the new measure replicated the three-factor model of the original CompACT, suggesting that the CompACT-10 retains the theoretical scope of the longer measure. The research provides promising evidence that the CompACT-10 is a reliable and valid tool for the brief assessment of psychological flexibility.

The attitude of young people to the use of artificial intelligence

The article examines the attitude of young people to the use of artificial intelligence. Young people, due to their greater psychological flexibility and adaptive capabilities, are more familiar with digital technologies. In the period of youth, the formation of a value-semantic sphere takes place. The respondents were young people in the number of 75 people. The comparative group consisted of respondents aged 40 to 50 years in the number of 50 people. The purpose of this work is to study the attitude of young people to the use of artificial intelligence. That will allow to understand more the attitudes of young people to the use of artificial intelligence from the perspective of benefits, motives of use and emotions; will provide reflection on the relationship of a person and the sphere of artificial intelligence. As research methods, the analysis of theoretical sources was used, the author’s questionnaire was used to study the attitude to the use of artificial intelligence among young people. The data obtained were processed using the methods of mathematical statistics Student’s T-criterion. The results of a study of attitudes to the use of artificial intelligence are presented. Significant differences in attitudes towards artificial intelligence systems were revealed in two groups of respondents on the possible benefits of artificial intelligence systems, the motives for their use of artificial intelligence, and the significance of the difference was revealed in relation to the emotions experienced by respondents of different ages when faced with these systems

Psychological flexibility, non-attachment, and materialism

Psychological flexibility, or the ability to flexibly respond to psychological events, may be associated with peoples' preferences for material versus experiential purchases, their attachment to objects and experiences, and their motivation for non-material purchases. The present research tested predictions that greater psychological flexibility and lesser psychological inflexibility are associated with lower materialism and non-attachment (Study 1) and with a greater preference for, and internal motivation toward, experiential versus material purchases (Study 2). Study 1 (N = 298 undergraduates) revealed relationships between psychological inflexibility, high materialism, and attachment, and between psychological flexibility, low materialism, and non-attachment. Non-attachment was a meditator in the relationships between both flexibility and inflexibility and materialism. Study 2 (N = 299 undergraduates) revealed that psychological flexibility was correlated with both experiential buying and autonomous reasons for experiential buying, whereas inflexibility was related to controlled and amotivated reasons for experiential buying. We discuss the research and practice implications of the current findings.

Psychological flexibility, distress, and quality of life in secondary progressive multiple sclerosis: A cross-sectional study

IntroductionOne of the strongest predictors of successful coping in multiple sclerosis (MS) is the extent to which one can accept the diagnosis and limitations associated with the disease. Acceptance is also one of three core processes of psychological flexibility – a malleable treatment target of some psychological therapies. This is the ability to notice and accept the presence of thoughts and feelings without being swept along by them, engaging in the present moment, and making decisions in line with personal values.Poor psychological flexibility is associated with elevated levels of distress in the general population. However, we do not know the level of psychological flexibility in people with MS, or its relationship to distress or quality of life when the disease becomes more physically disabling. The aims of this study were to determine the level of psychological flexibility, and its relationship with distress and quality of life in secondary progressive multiple sclerosis (SPMS), a subtype of MS with increased severity of disability and distress. MethodThis cross-sectional analytic study used data collected by the UK MS Register. Pre-existing data on distress, quality of life, disability, and demographics collected by the UK MS Register were combined with a psychological flexibility measure and its component parts, collected for the purpose of this study.Patient demographics and questionnaire data were recorded for distress, quality of life, and psychological flexibility. Pearson's correlations were used to examine bivariate relationships between distress, quality of life, disability and psychological flexibility. Whether psychological flexibility moderated the relationship between disability (predictor), distress and quality of life (outcomes) was also investigated. ResultsBetween February and March 2020, 628 participants with SPMS completed the CompACT and had a recent (<12 months) HADS questionnaire (Mage = 60.66, 70.90% women). On the HADS questionnaire subscales, 44% of the sample scored above the MS clinical cut-off (≥8) for anxiety (M = 7.09, SD = 4.57), and 30% above the clinical cut off (≥11) for depression (M = 8.35, SD = 4.21). Psychological flexibility (M = 81.94, SD = 22.60) and its components were each moderately negatively correlated with total distress (r = -0.65), anxiety (r = −0.58), and depression (r = -0.56). A second subsample (n = 434) completed the EQ-5D-5L health-related quality of life measure, which was moderately positively correlated with psychological flexibility (r = 0.47). A third subsample (n = 210) found a weak negative relationship between psychological flexibility and disability (r = -0.16), a weak positive relationship between distress and disability (r = 0.26), and a moderate negative relationship between quality of life and disability (r = -0.56). Psychological flexibility was not found to moderate the relationships between disability and anxiety, depression, or quality of life in SPMS. DiscussionGreater psychological flexibility was associated with lower self-reported distress and higher quality of life in this SPMS sample. It was not shown to moderate the extent to which physical disability predicts distress or quality of life in SPMS.These findings demonstrate that greater psychological flexibility is related to better coping outcomes (lower distress, higher quality of life) in SPMS. If psychological flexibility can be increased in people with SPMS, this could lead to a reduction in distress and improvement in quality of life, although directionality could not be attributed with these methods. Further longitudinal evidence and trials of psychological flexibility-focussed interventions are needed.

Psychological flexibility is associated with less diabetes distress and lower glycated haemoglobin in adults with type 1 diabetes.

Diabetes distress, self-efficacy and health literacy are associated with diabetes self-management and health outcomes. Measures of coping styles and their impact on diabetes self-management and diabetes-related distress might add value in identifying those at risk of poorer health outcomes. Current evidence of associations between psychological flexibility/inflexibility and diabetes-related health outcomes is limited. To measure associations of psychological flexibility, self-efficacy and health literacy with diabetes distress and glycated haemoglobin (HbA1c) in adults with type 1 diabetes. We surveyed 105 adults with type 1 diabetes attending a tertiary diabetes outpatient clinic (mean age 27 ± 7.1 years; 53% men; duration of diabetes 12.6 ± 8.5 years; HbA1c 72 ± 22 mmol/mol, 8.7 ± 2.0%; 34% using insulin pumps). We assessed psychological flexibility, self-efficacy, health literacy and diabetes distress. Regression models explored the relative contributions of different factors to diabetes distress and HbA1c. The majority of health literacy scores were in the low-risk range. Those with greater psychological flexibility had higher self-efficacy (r = 0.34; P < 0.01) and reported less diabetes distress (r = -0.54; P < 0.001). In multiple regression analyses, psychological flexibility and self-efficacy accounted for 36% of the variance in distress score (P < 0.001). Shorter duration of diabetes (P < 0.001) and greater psychological flexibility (P < 0.01) correlated with lower HbA1c. A 10-point (one standard deviation) higher psychological flexibility score corresponded to a 0.5% lower HbA1c. Greater psychological flexibility was associated with less diabetes distress and lower HbA1c. The psychological flexibility construct might inform alternative interventional approaches aiming to improve well-being and glycaemic control.

What Makes Entrepreneurs Happy? Psychological Flexibility and Entrepreneurs' Satisfaction

This paper investigates entrepreneurs' satisfaction. We conceptually replicate and extend Carree and Verheul’s (2012) Dutch study on the drivers of entrepreneurs' satisfaction with data from Belgian entrepreneurs. Thus, we respond to the need to replicate more in the (social) sciences, including entrepreneurship studies. The ‘extension’ aspect contributes novel theoretical understanding and empirical explanatory power of entrepreneurs' satisfaction. Specifically, the paper introduces psychological flexibility as an important new predictor of entrepreneurs' satisfaction. Indeed, we provide evidence that entrepreneurs with greater psychological flexibility are, on average, more satisfied.

Psychological Well-Being of Indian Mothers During the COVID-19 Pandemic

Abstract This study explored the associations among psychological well-being (PWB), self-compassion, psychological inflexibility (PI), and parenting stress (PS) in 242 urban Indian mothers of children 10 years old and younger in the context of the COVID-19 pandemic. Regression analysis revealed that greater self-compassion (SC), less PS, and greater psychological flexibility were associated with psychological well-being among the participants. Findings from this study contribute to research on maternal mental health by showing that, even in the context of the COVID-19 crisis, SC, PI, and PS are related to the PWB of urban Indian mothers, thus highlighting a need for evolving gender-based policies and emphasizing specific interventions for this vulnerable population.

The emerging role of acceptance and commitment therapy as a way to treat trauma and stressor related disorders

AimsThe aim of this work is to gather and evaluate scientific evidence about the clinical effects of Acceptance and Commitment Therapy (ACT) in the treatment of patients with trauma-related Post-Traumatic Stress Disorder (PTSD).MethodA literature search was conducted on PubMed platform, starting from the following MeSH terms: “Acceptance and Commitment Therapy”, “Trauma and Stressor Related Disorders”, “Psychological Trauma”. Studies obtained were analysed, corresponding to investigations based on an adult population with trauma and stressor related disorders.ResultThe search provided 13 results, of which 12 met the defined criteria. Different types of studies with variable samples were considered, including randomised clinical trials, longitudinal observational studies, narrative reviews and an analysis of case reports.Globally, ACT has been showing a crescent role in the treatment of individuals with trauma histories by enhancing positive outcomes and by being associated with greater psychological flexibility. It is increasingly considered to be well-suited to the treatment of trauma by targeting avoidance, coping strategies with emotional disengagement and persistent dissociation, aspects associated with greater PTSD symptom severity and related psychopathology.Furthermore, research suggests that acceptance-based treatments are helpful in promoting emotional, behavioural, and neural changes in psychological disorders characterised by disgust, shame and guilt that commonly co-occur with PTSD.Among the various exposure factors, we found a growing production of recent literature in which ACT has been applied in the context of oncology life-threatening settings, demonstrating significant improvements in symptoms and quality of life, as well as reductions in emotional disturbances, physical pain and traumatic responses.However, little is known about implementation and results of ACT in situations of trauma and psychiatric comorbidities. Data suggest that, when applied to individuals with psychosis and history of trauma, there is an improvement in overall severity and anxiety symptoms, emotion regulation strategies and a greater sense of engagement in care; nevertheless, reduction of specific trauma symptoms remains controversial. More mention is made about the growth of literature evaluating the application of ACT as a conjunctial therapeutic method for trauma and simultaneous addictive disorders.ConclusionOverall, despite limited published research currently available, some evidence starts to support ACT's promising role as an effective psychotherapeutic approach to trauma and stressor related disorders. Its application in situations where organic diseases represent stress factors has been growing. Future research should focus on clarifying the role of ACT in psychiatric comorbidity scenarios, allowing this psychotherapy to help individuals find a meaningful and valuable life beyond trauma.

Flexibilidad psicológica, burnout y satisfacción vital en profesionales que trabajan con personas afectadas de demencia

IntroductionThe clinical complexity of dementia, its physical burden, and the potential assaults associated with psychological and behavioral symptoms, could put healthcare workers working with dementia at high risk of burnout. Certain attitudes toward dementia and certain coping styles may be a protective factor against the stress experienced by these workers. On the other hand, it has been shown that a coping style based on psychological flexibility can prevent the development of burnout in the workplace. The present study analyzes the relationship between levels of burnout, psychological flexibility, attitudes towards dementia and life satisfaction in a sample of healthcare workers who work with people affected by dementia. MethodsA sample of 105 healthcare workers from the Ricard Fortuny Social Hospital was recruited (day hospital, hospitalization unit, and nursing home), and psychological flexibility (AAQII), burnout levels (MBI), life satisfaction (SWL), anxiety (STAI-R), and attitudes towards dementia (EAD) were assessed. ResultsPsychological inflexiblility showed a positive relationship with 2 dimensions of burnout (emotional exhaustion [r=.342, P<.01]; depersonalization [r=.328, P<.01]), and with anxiety (r=.723, P<.01), and also showed a negative relation with life satisfaction (r=−.485, P<.01) and affect attitude (r=−.209); p<.05). It was also found a negative relation between rejection attitude with emotional exhaustion (r=−.328, P<.01) and with depersonalization (r=−.328; P<.01). ConclusionsThose participants with greater psychological flexibility, in addition to feel more satisfaction with life, were found to be less likely to feel emotionally exhausted, to depersonalize patients with dementia, and felt more affection for them. On the other hand, no relationship was found between Burnout levels and the cognitive dimension of Attitudes towards dementia (the worker's knowledge of dementia). The results have significant implications regarding the type of training that is given to healthcare workers who work with people affected by dementia. Psychoeducational interventions promoting the psychological flexibility could help to reduce the risk of burnout in healthcare workers who work with dementia.

Psychological well-being and adjustment among type 2 diabetes patients: the role of psychological flexibility

ABSTRACT Elevated rates of psychological disorders are reported among those with type 2 diabetes (T2D). Thus, research into factors enhancing psychological aspects of well-being is critical in T2D. We examine the association between a multifaceted measure of Psychological Flexibility (PF), and its relationship to adjustment and well-being, among this population. Adults with T2D (N = 102) completed an online battery of self-reported questionnaires and were asked for demographics, general T2D features, treatment adherence, PF, adjustment, and well-being. We examined the association between PF (Psychological Flexibility Questionnaire, PFQ), adjustment to diabetes (ATT-39) and well-being (Mental Health Inventory), among adults with T2D. Greater PF was significantly associated with greater well-being, but unrelated to adjustment, which was positively associated with well-being. In a hierarchical regression analysis, perception of change as positive (one of the five PFQ factors) significantly contributed to the explained variance in well-being, beyond the contribution of adjustment. These findings indicate that positive perception of change may enhance well-being independently from adjustment to diabetes since these two constructs are distinct and independent. Such an association between PF and well-being may apply to other medical conditions. Implications for psychological intervention are discussed.

Psychological inflexibility and intolerance of uncertainty moderate the relationship between social isolation and mental health outcomes during COVID-19

The COVID-19 pandemic has had an enormous impact on human activity worldwide, in part due to many governments issuing stay-at-home orders and limiting the types of social interactions in which citizens can engage. Previous research has shown that social isolation can contribute to psychological distress. The impact of increased social isolation on mental health functioning during the COVID-19 crisis, as well as potential mechanisms to buffer this impact, have yet to be investigated. The current study explored the moderating role of psychological flexibility and related constructs on the relationships between social isolation and mental health outcomes during the COVID-19 pandemic. Cross-sectional data from 278 participants, the majority residing in the United States, were collected during a 3-week period from mid-April to early May 2020 via online survey. A series of hierarchical linear regression analyses indicated statistically significant relationships between social isolation and psychological distress (depression, anxiety, and stress), well-being, and valued living. Psychological inflexibility, intolerance of uncertainty, and emotional suppression significantly moderated these relationships in a number of instances. Greater psychological flexibility and acceptance of difficult experiences appeared to act as a buffer against the negative effects of increased social isolation, while amplifying the benefits of social connectedness. Implications for promoting mental health and buffering against the harmful effects of social isolation during the COVID-19 pandemic and beyond are discussed.

Resilience facilitates adjustment through greater psychological flexibility among Iraq/Afghanistan war veterans with and without mild traumatic brain injury.

Although many Iraq/Afghanistan warzone veterans report few problems with adjustment, a substantial proportion report debilitating mental health symptoms and functional impairment, suggesting the influence of personal factors that may promote adjustment. A significant minority also incur warzone-related traumatic brain injury (TBI), the majority of which are of mild severity (mTBI). We tested direct and indirect pathways through which a resilient personality prototype predicts adjustment of warzone veterans with and without mTBI over time. A sample of 264 war veterans (181 men) completed measures of lifetime and warzone-related TBIs, personality traits, psychological adjustment, quality of life, and functional impairment. Social support, coping, and psychological flexibility were examined as mediators of the resilience-adjustment relationship. Instruments were administered at baseline, 4-, 8-, and 12-month assessments. Structural equation models accounted for combat exposure and response style. Compared with a nonresilient personality prototype, a resilient prototype was directly associated with lower PTSD, depression, and functional disability, and higher quality of life at all time-points. Warzone mTBIs frequency was associated with higher scores on a measure of functional disability. Indirect effects via psychological flexibility were observed from personality to all outcomes, and from warzone-related mTBIs to PTSD, depression, and functional disability, at each time-point. Several characteristics differentiate veterans who are resilient from those who are less so. These findings reveal several factors through which a resilient personality prototype and the number of mTBIs may be associated with veteran adjustment. Psychological flexibility appears to be a critical modifiable factor in veteran adjustment. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Psychological Flexibility and Set-Shifting Among Veterans Participating in a Yoga Program: A Pilot Study.

Trauma-focused psychotherapies do not meet the needs of all veterans. Yoga shows some potential in reducing stress and perhaps even PTSD in veterans, although little is understood about the mechanisms of action. This study identifies preliminary correlates of change in PTSD and perceived stress for veterans participating in yoga. Nine veterans (seven males and two females) were recruited from an existing clinical yoga program and observed over 16 wk. Severity of PTSD symptoms (PCL-5) and perceived stress (PSS-10) were collected at baseline and weeks 4, 6, 8, and 16. Psychological flexibility (AAQ-II) and set-shifting (ratio of trail making test A to B) were collected at baseline and at week 6. Subjects attended yoga sessions freely, ranging from 1 to 23 classes over the 16 weeks. The Stanford University Institutional Review Board approved this research protocol. Self-reported PTSD symptoms significantly reduced while perceived stress did not. Lower baseline set-shifting predicted greater improvements in PTSD between baseline and 4 weeks; early improvements in set-shifting predicted overall reduction in PTSD. Greater psychological flexibility was associated with lower PTSD and perceived stress; more yoga practice, before and during the study, was associated with greater psychological flexibility. Other predictors were not supported. In a small uncontrolled sample, psychological flexibility and set-shifting predicted changes in PTSD symptoms in veterans participating in a clinical yoga program, which supports findings from prior research. Future research should include an active comparison group and record frequency of yoga practiced outside formal sessions.

The use of mobile phones to deliver acceptance and commitment therapy in the prevention of mother–child HIV transmission in Nigeria

The objective of this study was to determine if introducing acceptance and commitment therapy in the prevention of mother to child HIV transmission (PMTCT) programme using weekly mobile phone messages would result in improved mental health status of HIV-positive, pregnant women in Nigeria. We used a Solomon four-group (two intervention and two control groups) randomised design. The study population was 144 randomly selected, HIV-positive pregnant women attending four randomly selected PMTCT centres in Nigeria. The intervention groups were exposed to one session of acceptance and commitment therapy with weekly value-based health messages sent by mobile phone for three months during pregnancy. The control groups received only post-HIV test counselling. A total of 132 participants (33 per site) were enrolled in the study from the two intervention and two control sites. In the pre-tests, the intervention and control groups did not differ significantly with regard to demographics. Evaluation of the pre- and post-tests of the intervention group indicated significantly higher Action and Acceptance Questionnaire (AAQ-II) scores. The introduction of a mobile phone acceptance and commitment therapy programme may result in greater psychological flexibility in women diagnosed with HIV.

Mindfulness, Psychological Flexibility, and Counseling Self-Efficacy

The purpose of this study was to explore the mechanism by which counselor trainees’ mindfulness and psychological flexibility are positively associated with counseling self-efficacy. First, it was hypothesized that having fewer experiences of hindering self-focused attention (i.e., counselor trainees’ awareness of their own anxiety and distracting thoughts in sessions) would mediate the association between mindfulness and counseling self-efficacy. Second, it was hypothesized that having fewer experiences of hindering self-focused attention would mediate the association between psychological flexibility and counseling self-efficacy. Participants included 154 graduate counselor trainees. Results supported our hypotheses that counselor trainees with greater mindfulness reported having fewer experiences of hindering self-focused attention, which in turn was positively associated with counseling self-efficacy. Similarly, those with greater psychological flexibility also reported having fewer experiences of hindering self-focused attention, which in turn was positively associated with counseling self-efficacy. These findings were significant after controlling for age and number of practicum courses.

Mental Health Promotion as a New Goal in Public Mental Health Care: A Randomized Controlled Trial of an Intervention Enhancing Psychological Flexibility

We assessed whether an intervention based on acceptance and commitment therapy (ACT) and mindfulness was successful in promoting positive mental health by enhancing psychological flexibility. Participants were 93 adults with mild to moderate psychological distress. They were randomly assigned to the group intervention (n = 49) or to a waiting-list control group (n = 44). Participants completed measures before and after the intervention as well as 3 months later at follow-up to assess mental health in terms of emotional, psychological, and social well-being (Mental Health Continuum-Short Form) as well as psychological flexibility (i.e., acceptance of present experiences and value-based behavior, Acceptance and Action Questionnaire-II). Regression analyses showed that compared with the participants on the waiting list, participants in the ACT and mindfulness intervention had greater emotional and psychological well-being after the intervention and also greater psychological flexibility at follow-up. Mediational analyses showed that the enhancement of psychological flexibility during the intervention mediated the effects of the intervention on positive mental health. The intervention is effective in improving positive mental health by stimulating skills of acceptance and value-based action.

The influence of psychological flexibility on work redesign: Mediated moderation of a work reorganization intervention.

This quasi-experiment tested the extent to which an individual characteristic, psychological flexibility, moderated the effects of a control-enhancing work reorganization intervention in a call center. Results indicated that, compared with a control group, this intervention produced improvements in mental health and absence rates, particularly for individuals with higher levels of psychological flexibility. Findings also showed that these moderated intervention effects were mediated by job control. Specifically, the intervention enhanced perceptions of job control, and hence its outcomes, for the people who received it, especially for those who had greater psychological flexibility. Discussion highlights the benefits of understanding the processes (e.g., mediators, moderators, and mediated moderators) involved in work reorganization interventions.
