Psychotherapy and Psychotherapeutic Techniques for the Treatment of Vulvodynia: A Systematic Review and Meta-Analysis.

To assess the effectiveness of psychotherapy and psychotherapeutic techniques for reduction of vulvar pain and the improvement of sexual function and psychological adjustment in vulvodynia. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. PubMed, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, PsycInfo, and Clinical Trial Databases were searched on July 19, 2024. We included randomized controlled trials comparing psychotherapy interventions and psychotherapeutic techniques for vulvodynia. The risk of bias was assessed using the Cochrane Risk of Bias (RoB 2.0) tool. RevMan 5.4 was used for data synthesis. The Grading of Recommendations Assessment Development (GRADE) and Evaluation method was used to assess the strength of the evidence. A total of 1,884 articles were retrieved. Eight studies met the eligibility criteria and were included in the systematic review, comprising 689 participants. Two studies were included in the meta-analysis, these with 143 participants. When comparing the Acceptance and Commitment Therapy (ACT) with the control group, the mean difference (MD) in the pooled analysis for the Chronic Pain Acceptance Questionnaire did not differ significantly between ACT therapy and other therapies for posttreatment assessment (MD = 0.77; 95% CI = 3.45-4.99). Only 1 study was at high risk of bias due to a lack of clarity about the outcome measurement process. The GRADE rating for the certainty of the evidence for vulvar pain acceptance using ACT was considered low. Psychotherapy significantly improves vulvar pain, psychological adjustment, and sexual function in women with vulvodynia. Additionally, our meta-analysis showed that ACT and other psychotherapeutic interventions improve psychological adjustment through pain acceptance. However, more rigorous studies are needed to improve the quality of evidence and inform clinical practice.

Effectiveness of Acceptance and Commitment Therapy on Post-Traumatic Stress Symptoms, Psychological Inflexibility, and Self-Compassion in IPV Survivor University Women.

The aim of this study is to measure the effectiveness of an acceptance and commitment therapy (ACT)-based group intervention program on post-traumatic stress (PTS) symptoms, psychological inflexibility, and self-compassion in intimate partner violence (IPV) survivor university women. The research was conducted at a state university in İstanbul, Türkiye. Participants consisted of 22 IPV survivor university women with 10 in the treatment group and 12 in the waitlist-control group. Participants were assigned to groups based on their preferences. The treatment group participated in a 12-session ACT intervention group, each lasting 120 to 150 min. During this period, no intervention was applied to the waitlist-control group. At the end of the treatment, the intervention group's average PTS symptom scores and psychological inflexibility scores significantly decreased, while their self-compassion scores significantly increased. This effect persisted during the 1-month follow-up period. On the other hand, no changes were observed in the PTS, psychological inflexibility, and self-compassion levels of the control group. When comparing the treatment group with the control group, it was observed that the treatment group had significantly lower levels of PTS and psychological inflexibility and significantly higher levels of self-compassion in both the post-test and follow-up assessments. Consequently, the results revealed the effectiveness of the program on PTS, psychological inflexibility, and self-compassion among a group of IPV survivor university women. Thus, we concluded that ACT may serve as an effective therapy for addressing IPV among university women and that it is culturally applicable to the Turkish context.

Randomized Controlled Trial of Acceptance and Commitment Therapy for Fatigue Interference With Functioning in Metastatic Breast Cancer.

Fatigue is a highly prevalent and disabling symptom for patients with metastatic breast cancer (MBC). Evidence-based interventions for managing fatigue in advanced cancer populations are lacking. This phase II randomized controlled trial tested the effect of acceptance and commitment therapy (ACT) on fatigue interference with functioning in patients with MBC. Eligible patients were women with stage IV breast cancer who had moderate to severe fatigue interference. Patients completed a baseline assessment that included self-report measures of fatigue interference with activities, mood, and cognition (primary outcome) and sleep interference with functioning, engagement in daily activities, and quality of life (QOL; secondary outcomes). Then patients were randomly assigned to six weekly telephone-delivered sessions of either ACT (n = 116) or education/support (n = 120). Follow-up assessments occurred at 2 weeks, 3 months, and 6 months postintervention (means, 9.69, 20.51, and 33.59 weeks postbaseline, respectively). Linear mixed model analyses showed that compared with patients in the education/support condition, patients in the ACT condition reported significantly less fatigue interference (P = .018). These results were significant at 2 weeks and 6 months postintervention. ACT's effect on sleep interference was not statistically significant after the Sidak adjustment for multiple comparisons (P = .037). ACT patients showed a steady decline in sleep interference, a trend that was not found for education/support patients. Engagement in daily activities and QOL did not significantly differ between study groups, except for functional QOL (P = .006). Compared with education/support patients, ACT patients showed significantly better functional QOL at 2 weeks and 6 months postintervention. Results suggest that a brief, telephone-delivered ACT intervention can reduce fatigue interference with functioning in patients with MBC.

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

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

Mechanisms of change in an online acceptance and commitment therapy intervention for insomnia

Insomnia, i.e., difficulty falling asleep or staying asleep, is a common condition that is connected to many psychological and physical problems. Online-based Acceptance and Commitment Therapy (ACT) has recently been introduced as an option for treating insomnia. However, our understanding is yet limited on what happens during an online ACT intervention or what underlying mechanisms are critical for outcomes. This study addressed this gap by investigating mediators of a brief self-guided online ACT intervention for adults suffering from subclinical and clinical insomnia. A total of 86 adults were randomized to an intervention group (n = 43) or a waitlist control group (n = 43). Mediator models were used to investigate the effects of online ACT on subjective sleep complaints through changes in daytime sleepiness, dysfunctional beliefs, psychological symptoms, mindfulness, and thought suppression. Two models showed significant indirect effects: The online ACT intervention decreased participants’ thought suppression and depressive symptoms, which then decreased subjective sleep complaints. Other models did not yield significant mediating effects. Acceptance and mindfulness-based approaches may serve as viable options for other existing insomnia treatments. Future studies are encouraged to be conducted, especially concerning flexibility and inflexibility processes as possible mechanisms of change in online ACT for insomnia.

P0850 Managing pain in people with Crohn’s Disease: feasibility testing of an Acceptance and Commitment Group Therapy intervention

Abstract Background Chronic abdominal pain in Crohn’s disease (CD) significantly impacts on quality of life (QoL) (1). Current management strategies are unsatisfactory. Acceptance and Commitment Therapy (ACT) is emerging as an approach in other areas (2). This feasibility study aimed to test an 8-week, online group ACT intervention in reducing the impact of CD pain. Methods A feasibility crossover RCT with the aims of: (1) 48 participants recruited; 2) 75% attend 5 of 8 sessions; (3) <20% missing questionnaire data; (4) >50% deem the intervention acceptable. We planned to recruit 48 patients (≥18 years old, diagnosed with CD for ≥6 months and reported a pain-interference score of ≥4/10, Brief Pain Inventory) with 1:1 allocation ratio into intervention arm (IA) and control crossover arm (CC). The CC received treatment as usual (TAU) for 16 weeks, before beginning the online intervention. Feasibility measures included recruitment, retention, and completion rates; clinical outcomes included pain severity and interference, fatigue, distress, stress, anxiety and depression, QoL, and functional impairment. The outcome measures were collected at baseline, weeks 8-10 and 16-18 with additional measures for CC at week 24-26 and 32-34. Patients were recruited from outpatient clinics in two large NHS hospitals, and via the UK IBD BioResource. Descriptive statistics and thematic analysis (with Patient and Public involvement) were employed to analyse quantitative and qualitative data respectively. Results Despite invitations being sent to over 1000 patients, only 95 volunteered. The screening process revealed low reported levels of pain (<4) or/and a need for medical intervention for CD. 27 out of the 48 target were recruited (28% successful recruitment rate), mean age 45 (range 19-71). Eight participants withdrew from the study before the intervention (70% retention rate), one dropped out after session 1, 18 patients completed the intervention (67% completion rate). The feasibility aims 1,2 and 3 were not achieved. Hence, the intervention and the study are deemed not feasible. There were insufficient clinical data to analyse findings in detail. Qualitative data indicate that patients found the group therapeutic, and the content helped to re-evaluate their relationship with pain (Figure 1). Many reported using ACT techniques after the group ended and several felt that the intervention should be offered sooner after IBD diagnosis. Conclusion An online group ACT intervention is not feasible in its current format. Although some reported benefits, the overall impact is unclear. The difficulty recruiting patients highlights several issues suggesting more work needs to be done to successfully reach and engage this population.

Efficacy and cost-effectiveness of an ACT and compassion-based intervention for women with breast cancer: study protocol of two randomised controlled trials {1}

BackgroundBreast cancer is the most diagnosed cancer in women worldwide and carries a considerable psychosocial burden. Interventions based on Acceptance and Commitment Therapy (ACT) and compassion-based approaches show promise in improving adjustment and quality of life in people with cancer. The Mind programme is an integrative ACT and compassion-based intervention tailored for women with breast cancer, which aims to prepare women for survivorship by promoting psychological flexibility and self-compassion. A pilot study of the Mind programme has shown acceptability and preliminary efficacy in improving quality of life and psychological health. This paper presents the study protocol of two randomised controlled trials that aim to test the efficacy and cost-effectiveness of an optimised version of the Mind programme in women with breast cancer.MethodsParticipants will be women diagnosed with breast cancer randomly assigned to the Mind programme or a support group intervention (active control) in a 1:1 ratio for study 1, while study 2 includes one more arm (treatment as usual; inactive control) and a 2:2:1 ratio. Both interventions will be delivered weekly via an 8-session face-to-face or online group format. Data will be collected at baseline, post-treatment and 6-month follow-up. The efficacy and cost-effectiveness of the two interventions will be assessed. Treatment outcomes will comprise cancer-specific quality of life (primary outcome), anxiety and depressive symptoms, psychological flexibility, self-compassion, health-related quality of life, resource use, and intervention’s acceptability and feasibility. Study 1 will also include immunological and epigenetic markers associated with breast cancer prognosis and mental health. Outcome assessors will be blind to group allocation. Statistical analyses will be conducted using an intention-to-treat approach. Analyses of moderators and mediators of change will also be performed.DiscussionThese trials examine the efficacy and cost-effectiveness of an integrative ACT and compassion-based intervention tailored for women with breast cancer. Greater improvements in psychosocial, biological and resource use are expected in the Mind group, when compared to the control group(s). Results will likely support the potential benefits of the Mind programme for breast cancer patients and highlight the clinical relevance of integrative and holistic interventions in oncology.Trials registration {2a, 2b}ClinicalTrials.gov NCT05642897 and NCT06212414.

Acceptance and Commitment Therapy for Well-Being at Worksites: Charting the Field for Enhancing Its Applicability

The advent of the “New Era for Mental Health” has made the management of this intangible asset one of the hottest topics in the workplace. It is the leading cause of disability today. Organizations are encouraged to use psychological interventions to promote and prevent more sustainable and productive workplaces. The aim of this article is to develop an exploratory and systematic mixed review that combines quantitative and narrative analysis to synthesize the available literature on the use of Acceptance and Commitment Therapy (ACT) interventions in the workplace—an increasingly popular therapy to address this challenge. This review provides a comprehensive reflection of the existing state of the art, gaps in current research, and future directions on the topic. The analysis of 59 articles collected from Web of Science (WoS), Scopus, and PubMed databases from 2000 to 2023 reveals, firstly, that the use of ACT interventions in the workplace is increasing significantly, with an upward trend over the last 5 years and a presence in high-impact journals. Secondly, the research themes identified reveal that ACT intervention is still focused on clinical settings with limited presence in other sectors or organizational settings—such as education, business management, or return-to-work programs. Based on these results, this research underscores the growing importance of ACT in the workplace, revealing seven research opportunities to extend its application across various sectors and accelerate its effective implementation in industry and academia, thereby enhancing mental health and productivity.

SLEEP QUALITY IMPROVES IN DEMENTIA CAREGIVERS USING ONLINE SELF-GUIDED ACCEPTANCE AND COMMITMENT THERAPY

Abstract Transdiagnostic interventions treat multiple conditions by addressing common underlying mechanisms. Randomized controlled trials, systematic reviews, and meta-analyses support that Acceptance and Commitment Therapy (ACT) is a transdiagnostic mindfulness-based Cognitive Behavioral Therapy that improves anxiety, depression, pain, etc. in diverse populations. ACT efficacy is supported in dementia caregivers, typically studied via psychological or care-related outcomes. ACT improves sleep in cancer caregivers, and sleep is often disturbed in dementia caregivers. The current study examines if sleep quality improves in (N=80) dementia caregivers engaging with a caregiver-tailored six-session online, self-guided ACT program. Participants completed the Sleep Quality Scale and other assessments at T1 (pre-intervention), T2 (post-intervention) and T3 (6-week followup). A sleep-related item from a depression inventory assessed sleep restlessness. Items from a behavioral symptom inventory assessed the extent to which care receivers woke the caregiver or others in the night, and assessed caregivers’ stress appraisal of this experience. We did not hypothesize that care receivers’ wakefulness would be impacted, but hypothesized improvements in the other caregiver sleep indicators. Repeated measures ANOVA identified that caregivers improved average sleep quality [F(2,158)=7.907, p<.001; partial eta-squared =.091] and reported less sleep restlessness [F(2,156)=10.039, p<.001; partial eta-squared =.114]. Post hoc comparisons identified change occurring between T1-T2 (Intervention phase), sustained over time (T3). Care receivers’ waking behavior did not change over time (p=n.s.), but caregivers experiencing this behavior across all timepoints (N=17), reported being less bothered by it [F(2,32)=5.457, p<.01; partial eta-squared =.254]. ACT interventions offer promise in improving sleep experiences for dementia caregivers.

Comparison of the Effects of Acceptance and Commitment Therapy and Emotion-Focused Therapy on Mental Vitality in Caregivers of Elderly Parents

Introduction: Caregiving burden for older adults can impose significant physical and emotional demands, leading to a reduction in mental vitality among caregiver children. Effective psychological interventions are crucial to enhance their well-being. Methods: This quasi-experimental study included two psychological interventions: Acceptance and Commitment Therapy (ACT) and Emotion-Focused Therapy (EFT), with baseline, post-test, and follow-up phases, along with a control group for comparison. The research population comprised female caregivers who accompanied their older adults to health centers in Tehran. From a total of 169 individuals, 45 participants were selected through convenience sampling and were randomly assigned to three groups of 15 participants each, forming two experimental groups and one control group. Data were collected using the Ryan and Frederick Mental Vitality Questionnaire, and multivariate covariance analysis was applied for data analysis to assess the effectiveness of the interventions. Results: The analysis showed that both ACT and EFT interventions significantly improved the mental vitality of caregiver children in the post-test and follow-up stages compared to the control group (p = 0.001). Additionally, EFT demonstrated a greater impact on enhancing mental vitality compared to ACT. Conclusion: Emotion-focused interventions, such as EFT, can be considered a more effective approach for improving the mental vitality of caregiver children of older adults. This highlights the importance of incorporating tailored emotional support strategies in caregiver assistance programs.

Work participation after receiving multidisciplinary treatment or acceptance and commitment therapy intervention for return to work: long-term follow-up of a randomized controlled trial among sick-listed individuals with mental disorders and/or chronic pain

BackgroundThe return-to-work (RTW) process for individuals on long-term sick leave can be complex. Vocational rehabilitation may facilitate RTW; however, many intervention studies often have relatively short follow-up periods. The purpose of this study was to assess long-term work participation 2–7 years after the initiation of a three-armed randomized controlled trial aimed at RTW for individuals on long-term sick leave because of mental disorders and/or chronic pain.MethodsThis study followed 220 participants out of 402 (response rate 55%, 205 female) who had previously participated in a randomized controlled trial. They were allocated to one of three groups: multidisciplinary team assessment and individualized treatment (MDT), acceptance and commitment therapy (ACT) or a control group. The participants were followed up at two, three, four, five, six, and seven years after inclusion. The outcome, work participation, was assessed using registry data and defined as having the main source of annual income from paid work during the follow-up years.ResultsParticipants in the MDT intervention group were, to a larger extent, in paid work during follow-up in years four (9.0% points), five (2.5% points), six (7.6% points), and seven (4.1% points) after inclusion, compared to the control group. Participants in the ACT intervention group were, to a larger extent, in paid work during follow-up in years four (14.8% points), six (17.6% points), and seven (13.9% points) after inclusion, compared to the control group.ConclusionThis study, primarily involving female individuals on long-term sick leave, suggests that both MDT and ACT interventions can improve long-term work participation. The results also indicate some time-lag effect of the interventions.Trial registrationThe original randomized study was registered at the Clinicaltrials.gov Register Platform (ID NCT03343457); registered on November 15, 2017 (retrospectively registered).

The effect of Acceptance and Commitment Therapy on perceived stress, rumination, and distress tolerance in women with Bulimia Nervosa

ABSTRACT This study aimed to evaluate the efficacy of Acceptance and Commitment Therapy (ACT) in mitigating perceived stress, rumination, and distress tolerance among women diagnosed with Bulimia Nervosa (BN) in Ahvaz, Iran. A quasi-experimental pre-test-post-test design with a control group was employed. The target population consisted of all female BN patients referred to the Ahvaz Binge Eaters Association between February and May 2022. Patients were definitively diagnosed with BN by a clinical specialist using a structured clinical interview adhering to DSM-5 criteria. From an initial pool of 91 patients, 50 were randomly selected for participation and subsequently assigned to either the experimental or control group, with each group comprising 25 individuals. Pre-test analysis revealed no significant group differences in perceived stress, rumination, or distress tolerance among women with BN. However, post-test scores indicated a significant decrease in both perceived stress and rumination within the experimental group compared to the control group (p < .01). Furthermore, the post-test analysis demonstrated that ACT intervention significantly improved distress tolerance in women with BN (p < .01). These findings suggest that ACT may be a promising therapeutic approach for alleviating psychological distress and enhancing emotional regulation in individuals grappling with BN.

Efficacy of Acceptance and Commitment Therapy in Social Anxiety Disorder: A Systematic Review and Meta-analysis

Background: Acceptance and commitment therapy (ACT) is a novel third-wave therapy becoming popular in the management of various anxiety disorders. In this systematic review, we wish to gather the data that have been studied to determine the effectiveness of ACT in treating social anxiety disorder (SAD). Methods: This study followed standard systematic review guidelines and was registered with PROSPERO prior to undertaking the review. Databases, namely PubMed, PsycINFO, Ovid MEDLINE, and gray literature (ClinicalTrials.gov, BASE) with relevant keywords, were searched from inception to February 2024. Randomized controlled trials encompassing both clinical and nonclinical populations aged more than 10 years diagnosed with SAD were included. These trials compared ACT with wait list controls (n = 6) and cognitive behavioral therapy (n = 3). The primary outcome focused on the reduction of symptoms associated with social anxiety, while quality of life served as a secondary outcome. Measures of effect were determined through pre-test and post-test mean values, alongside their respective standard deviations. The random effect model was used to calculate pooled effect size. The quality of the included papers was assessed using Cochrane RoB-1. Covidence software was used for the initial selection of studies, and meta-analyses were performed using RevMan software. Results: From the initial 442 study records that were searched, finally 9 studies were included for the systematic review, of which 6 studies were found suitable for meta-analysis. The pooled estimate for studies comparing ACT with wait list found that the overall effect size for social anxiety symptoms was g = −1.28 (95% confidence interval of -1.88, -0.69) favoring ACT intervention significantly. Conclusion: This review found that ACT is efficacious in treating SAD. Most of the studies included were conducted in adolescent females. Varying ACT intervention modalities were incorporated, with the primary outcome assessed using a range of scales. The results of our meta-analysis should be interpreted with caution because of heterogeneity and smaller number of studies being included. ACT can be considered a psychotherapeutic option for the management of SAD.

Effectiveness of Acceptance and Commitment Therapy (ACT) on disease acceptance for breast cancer patients: Study protocol of a randomized controlled trial.

Breast cancer patients face significant psychological challenges, including difficulties in accepting the diagnosis, treatment, and long-term impact of the disease. Acceptance and Commitment Therapy (ACT) has shown promise in enhancing acceptance and psychological flexibility in various populations. This study aims to investigate the effectiveness of ACT in promoting disease acceptance among breast cancer patients through a randomized controlled trial. This study will recruit 90 breast cancer patients and randomly allocate them to an ACT intervention or control group. The ACT intervention, focusing on acceptance, mindfulness, value clarification, and committed action, will be delivered over 4 weeks. Meanwhile, the control group will receive standard care with non-therapeutic intervention. The study's primary outcome is disease acceptance, while secondary outcomes include depression, anxiety, social support, quality of life (QoL), and psychological inflexibility. Data will be collected at three points: baseline, post-intervention, and three-month follow-up. Statistical analysis will compare outcomes between groups to evaluate the effectiveness and mechanism of this intervention using covariance and mediation analysis. This study evaluates the effectiveness of ACT in promoting disease acceptance among breast cancer patients. It hypothesizes that the ACT group will show higher disease acceptance and improvements in social support, QoL, and psychological flexibility compared to the control group. The findings will contribute to research on psychological interventions and demonstrate ACT's effectiveness in enhancing disease acceptance. The research project is registered in the ClinicalTrials (NCT05327153).

Acceptance and Commitment Therapy for Hypersexuality: A Pilot Study

Hypersexuality refers to the inability to control sexual desire. Despite it has shown serious consequences for physical, psychological and social health, the evidence of available psychological interventions is still insufficient. In this open-label pilot study, an Acceptance and Commitment Therapy (ACT) intervention was conducted with adults with clinically significant levels of hypersexuality aimed to examine its feasibility and usefulness. The intervention consisted of eight weekly online individual psychological intervention sessions. Outcome self-report measures were administered at baseline, after the intervention and a 3 months follow-up. Behavioral and subjective informed changes in sexual practices were weekly assessed through self-monitoring. Twelve participants (M age = 38.8 ± 11.5 years, 83.3% male, 66.7% homo or bisexual) completed the intervention. The feasibility was found to be good, with all the participants completing the training and high levels of satisfaction. Hypersexuality, psychological flexibility, cognitive fusion and mindfulness scores significantly improved after the ACT intervention, with large effect sizes. Clinically significant changes in hypersexuality were found for the vast majority of participants, besides reductions in the time dedicated to planning and practicing sex and the sexualized drug use. Results indicate that ACT-based interventions may be considered feasible and potentially effective therapeutic alternatives for hypersexuality.

Effects of acceptance and commitment therapy on trauma-related symptoms: A systematic review and meta-analysis.

Acceptance and commitment therapy (ACT) is a third-wave cognitive behavioral therapy that has shown promise as an effective treatment for reducing trauma-related symptoms. Although there have been systematic reviews on the clinical effectiveness of ACT for posttraumatic stress disorder, there are no known meta-analyses published on the impact of ACT in adult populations with trauma-related symptoms. Hence, the purpose of this meta-analysis and systematic review was to update the literature and assess the effectiveness of ACT interventions for decreasing trauma-related distress in adults who have developed trauma symptoms following exposure to one or more traumatic events. A systematic review of the literature was completed, and between-groups random effects meta-analysis was conducted assessing trauma symptom reduction at the initial posttest. Subgroup analyses were also performed to assess differences between groups based on research design, type of trauma, and comparator group. A meta-analysis of 11 studies revealed a moderate and statistically significant overall effect of ACT on symptom reduction at immediate posttest (Hedges' g = -.423, 95% CI [-.605, -.240]; I² = 25.75%), indicating that on average, those who received ACT interventions reported fewer trauma symptoms postintervention than those in various comparison groups. Ultimately, this research provides additional evidence supporting the effectiveness of ACT interventions for clients reporting trauma-related concerns.
