Abstract Background As treatment of choice in promoting psychological flexibility, Acceptance and Commitment Therapy (ACT) was found to be effective in several conditions, and among different populations, including weight management in individuals with obesity. However, the mechanism of action of psychological flexibility is less known. The aim of the present study is, within the context of a brief ACT intervention for behavioral change and behavioral maintenance of a healthy lifestyle in a sample of inpatients with obesity, to explore the effect of each subcomponent of the psychological flexibility model on treatment processes and outcomes. Methods A randomized controlled trial will be conducted. Ninety Italian adult inpatients with obesity attending a rehabilitation program for weight loss will be randomly allocated into three experimental conditions targeting respectively each subcomponent of the psychological flexibility model: group Engage focused on values-oriented behaviors, group Openness focused on acceptance and cognitive defusion, and group Awareness focused on being present and aware of thoughts, feelings, and behaviors at every moment. Weight, BMI (kg/m2), the Psychological General Well-Being Inventory (PGWBI), the Outcome Questionnaire-45.2 (OQ-45.2), the Depression Anxiety and Stress Scale (DASS-21), the Difficulties in Emotion Regulation Scale (DERS), the Dutch Eating Behaviors Questionnaire (DEBQ), the Brief Values Inventory (BVI), the Committed Action Questionnaire (CAQ), the Italian-Cognitive Fusion Questionnaire (I-CFQ), the Five Facet Mindfulness Questionnaire (FFMQ), and the Acceptance and Action Questionnaire (AAQ-II) will be assessed at the beginning (time 0), at the end of psychological intervention (time 1), and after 3 (time 2) and 6 months (time 3) and 9 months (time 4) from discharge. During the following month after discharge, outpatients will be monitored in their adherence to a healthy lifestyle, using a wearable device. To assess the effectiveness of the intervention, mixed between-within 3 (conditions) × 4 (times) repeated measure ANOVAs will be conducted to examine changes from time 0 to time 1, 2, 3, and 4 in means of weight, BMI, and means of scores PGWBI, OQ-45.2, DASS, DERS, DEBQ, AAQ-II, BVI, CAQ, I-CFQ, and FFMQ, between three groups. Discussion This study will contribute to clarify the mechanism of action of each subcomponent of the psychological flexibility model and understand its impact on the promotion of a healthy lifestyle.

Pilot Randomized Controlled Trial

Weight self-stigma, in which individuals internalize stigmatizing messages about weight, is a prevalent problem that contributes to poor quality of life and health. This pilot randomized controlled trial evaluated acceptance and commitment therapy (ACT) guided self-help using The Diet Trap for 55 overweight/obese adults high in weight self-stigma. Participants were randomized to the ACT self-help book plus phone coaching (GSH-P; n = 17), self-help book plus email prompts only (GSH-E; n = 20), or a waitlist condition ( n = 18), with online self-report assessments at baseline and posttreatment (8 weeks later). Participants reported high satisfaction ratings and engagement with the ACT self-help book, with no differences between GSH-P and GSH-E. Both GSH-P and GSH-E improved weight self-stigma relative to waitlist with large effect sizes. There were mixed findings for health outcomes. The GSH-P condition improved more on healthy eating behaviors and general physical activity, but neither ACT condition improved more than waitlist on self-reported body mass index, emotional eating, and a second measure of physical activity. Results suggest an ACT self-help book with email prompts can reduce weight self-stigma and potentially improve some health behavior outcomes. Phone coaching may provide additional benefits for generalizing ACT to diet and physical activity.

The purpose of this study was to examine acceptance and commitment therapy (ACT) as a standalone treatment for trichotillomania in a randomized controlled trial of adults and adolescents. Participants consisted of a community sample of treatment seeking adults and adolescents with trichotillomania. Of the eligible 39 participants randomized into treatment and waitlist groups, 25 completed treatment and were included in the final analysis. Treatment consisted of a 10-session ACT protocol. Multiple mixed models repeated measures analyses were utilized to evaluate changes in trichotillomania symptom severity, daily number of hairs pulled and urges experienced, and experiential avoidance from pretreatment to posttreatment. Findings indicated significant changes in symptom severity and daily hairs pulled, but not daily urges experienced or psychological flexibility. However, psychological flexibility saw a 24.5% decrease in the treatment group and reduced from clinical to subclinical levels on average. This study suggests that ACT alone is an effective treatment for adults and adolescents with trichotillomania. Outcomes appear to be similar to trials that combined ACT and habit reversal training (HRT).
