Registration Number
NCT05885438
Lead Sponsor
University of Alabama at Birmingham
Brief Summary

The goal of this clinical trial is to investigate if a 4-hour acceptance and commitment therapy workshop can help the adoption and maintenance of healthy lifestyle behaviors in women with obesity. The objectives are as follows:

1. To assess changes in ACT-related constructs before and after the workshop

2. To assess changes in other psychological constructs that have been shown to hinder successful weight management before and after the workshop

3. To assess changes in dietary and physical activity behaviors before and after the workshop. Participants will complete baseline questionnaires and anthropometric measures at three time points: baseline, 1 week after the workshop, and 1 month after the workshop. Researchers will compare an active intervention group to a waitlist control group to investigate the efficacy of the workshop.

Detailed Description

Acceptance and commitment therapy interventions demonstrate efficacy for weight loss. ACT-based workshops represent an innovative and potentially scalable application of this approach to obesity treatment. 70 women will be recruited to participate. Half of the participants (n = 35) will receive a brief ( approximately 4-hour) workshop that aims to facilitate the development and maintenance of healthy lifestyle behaviors using ACT principles such as valued living and committed action. Outcomes will be assessed at baseline, 1-week, and 1-month post-intervention.

Primary Outcome Measures
NameTimeMethod
Change from baseline in psychological flexibility at 1 monthbaseline and 1 month

The Acceptance and Action Questionnaire for Weight-Related Difficulties is a validated, self-report measure and will be used to assess change in psychological flexibility. Possible scores range from 0-22, with higher scores indicating greater psychological flexibility.

Change from baseline in distress tolerance at 1 monthbaseline and 1 month

Distress tolerance will be measured using the Distress Tolerance Scale- Short Form (DTS), a validated, self-report measure. Possible scores range from 15 to 75, with higher scores indicating better distress tolerance

Change from baseline in psychological flexibility at Week 1Baseline and 1 week

The Acceptance and Action Questionnaire for Weight-Related Difficulties is a validated, self-report measure and will be used to assess change in psychological flexibility. Possible scores range from 0-22, with higher scores indicating greater psychological flexibility.

Change from baseline in valued living at Week 1baseline and 1 week

The Valued Living Questionnaire is a validated, self-report measure to assess the extent to which an individual is living in a way that is consistent with their core values. Scores range from 10-100, with higher scores indicating greater consistency between values and behavior.

Change from baseline in distress tolerance at Week 1baseline and 1 week

Distress tolerance will be measured using the Distress Tolerance Scale- Short Form (DTS), a validated, self-report measure. Possible scores range from 15 to 75, with higher scores indicating better distress tolerance

Change from baseline in valued living at 1 monthbaseline and 1 month

The Valued Living Questionnaire is a validated, self-report measure to assess the extent to which an individual is living in a way that is consistent with their core values. Scores range from 10-100, with higher scores indicating greater consistency between values and behavior.

Secondary Outcome Measures
NameTimeMethod
Change from baseline in emotional eating at 1 monthbaseline and 1 month

Emotional eating will be measured using the Emotional Eating Scale. This is a 25 item self-report measure with possible scores ranging from 25 to 125. Higher scores suggest greater likelihood to eat in response to emotionality.

Change from baseline in diet quality at 1 monthbaseline and 1 month

Dietary quality will be measured using the Rapid Eating Assessment for Participants- Shortened Version (REAPS-S). The REAPS-S is a 16-item, self-report questionnaire with possible scores ranging from 16 - 48, with lower scores indicating a less healthy diet.

Change from baseline in body weight at 1 weekbaseline and 1 week

Participants will be weighed to the nearest 0.1 kg.

Change from baseline in body weight at 1 monthbaseline and 1 month

Participants will be weighed to the nearest 0.1 kg.

Change from baseline in weight self-stigma at Week 1baseline and 1 week

Weight self-stigma will be measured using the Weight Self-Stigma Questionnaire, a validated self-report measure. This is a 23-item measure, with scores ranging from 12- 60. higher scores indicate more weight self-stigma.

Change from baseline in body image at Week 1baseline and 1 week

Body image will be measured using the Body Shape Questionnaire, a validated, 14 item self report measure. Scores range from 14 to 84, with higher scores indicating more negative body image.

Change from baseline in emotional eating at Week 1baseline and 1 week

Emotional eating will be measured using the Emotional Eating Scale. This is a 25 item self-report measure with possible scores ranging from 25 to 125. Higher scores suggest greater likelihood to eat in response to emotionality.

Change from baseline in weight self-stigma at 1 monthbaseline and 1 month

Weight self-stigma will be measured using the Weight Self-Stigma Questionnaire, a validated self-report measure. This is a 23-item measure, with scores ranging from 12- 60. higher scores indicate more weight self-stigma.

Change from baseline in body image at Month 1baseline and 1 month

Body image will be measured using the Body Shape Questionnaire, a validated, 14 item self report measure. Scores range from 14 to 84, with higher scores indicating more negative body image.

Change from baseline in physical activity at Week 1baseline and 1 week

Physical Activity will be measured using the International Physical Activity Questionnaire -Short Form. This is a validated self report measure that provides information on frequency (times per week) and duration (minutes per session) of physical activity undertaken per week.

Change from baseline in physical activity at 1 monthbaseline and 1 month

Physical Activity will be measured using the International Physical Activity Questionnaire -Short Form. This is a validated self report measure that provides information on frequency (times per week) and duration (minutes per session) of physical activity undertaken per week.

Change from baseline in diet quality at Week 1baseline and 1 week

Dietary quality will be measured using the Rapid Eating Assessment for Participants- Shortened Version (REAPS-S). The REAPS-S is a 16-item, self-report questionnaire with possible scores ranging from 16 - 48, with lower scores indicating a less healthy diet.
