Brief summary

This study aimed to investigate whether Acceptance and Commitment Therapy/Training would be helpful to reduce weight-related experiential avoidance among individuals who reported weight concern

Detailed description

This quasi-experimental study aimed to examine the efficacy of Acceptance and Commitment Therapy/Training (ACT) in reducing weight-related experiential avoidance. Data were collected with a convenience sampling technique. After obtaining ethical approval, participants were invited to participate in the study via advertisements, and online posts. Due to the small sample size, participants who were willing to attend group discussions were included in the experimental group. Participants in the control group did not receive manipulation. All participants were provided with an informed consent form. All participants completed a questionnaire measuring outcomes (weight-related experiential avoidance, general experiential avoidance, eating attitudes, and social physique anxiety) at pre-test, post-test, and follow-up. Participants in the experimental group received ACT training including 6 sessions. The protocol was adapted from Pearson et al. (2012) with their permission. Each session took approximately 80 mins. Several aspects of ACT approach were discussed in the sessions. In session one, ACT approach was introduced. In session two, creative hopelessness was discussed. In session three, control strategies related to weight concern were identified. In session four, mindfulness exercises were completed. In the fifth session, values for meaningful life experience were discussed. In the last, sixth session, the ways to commit to action were discussed. Each session included exercises and homework. At the end of the study, the participants were provided with debrief form.

Design outcomes

Primary

MeasureTime frameDescription
Change in weight-related experiential avoidanceAt three time points (pre-intervention [baseline], immediately after the intervention, and at three weeks after the intervention)It was measured by Acceptance and Action Questionnaire for Weight-Related Difficulties-Revised. The scale includes 10 items that are rated on 7 points scale (1 = not true at all - 7 = completely true). Higher scores indicate greater weight related experiential avoidance.

Secondary

MeasureTime frameDescription
Change in eating attitudesAt three time points (pre-intervention [baseline], immediately after the intervention, and at three weeks after the intervention)Eating attitudes were measured by The Eating Attitudes Test-26. It includes 26 items that are rated on 4 point scale ('3 = Always, 2 = Usually, 1 = Often, 0 = Sometimes, Rarely, and Never'). The last item (26) requires reverse coding. Scores 20 and above indicate dysfunctional eating attitudes.
Change in general experiential avoidanceAt three time points (pre-intervention [baseline], immediately after the intervention, and at three weeks after the intervention)It was measured by Acceptance and Action Questionnaire-II. It includes 7 items that are rated on 7 point scale (1 = never true - 7 = always true). Minimum and maximum scores range between 7 and 49 points. Higher scores indicate greater general experiential avoidance (psychological inflexibility).
Change in social physique anxietyAt three time points (pre-intervention [baseline], immediately after the intervention, and at three weeks after the intervention)It was measured by The Social Physique Anxiety Scale. The scale includes 12 items are rated on a 5-point scale (1=not at all true to 5=extremely true). Higher scores indicate a higher level of anxiety related to the social physique. Only item 1, 2, 5, 8 and 11 requires reverse coding.
