- Registration Number
- NCT05529758
- Lead Sponsor
- East Carolina University
- Brief Summary
The current study aims to test a third-wave based IWB intervention paired with a standard BWLP delivered through video conferencing software.
- Detailed Description
Internalized weight bias (IWB), has been shown to impact mental (e.g., depression and anxiety) and physical health (e.g., cardiometabolic functioning), as well as weight loss and weight loss associated behaviors (e.g., interference with exercise and healthy eating). These associated behaviors especially pose a risk for weight regain and disruption of healthy weight loss. Therefore, given the association between IWB and weight loss associated behaviors, as well as the psychological and health risks associated with IWB, it is clear that IWB interventions are also needed independently and in conjunction with behavioral weight loss programs (BWLPs). Interventions using third-wave strategies (such as acceptance commitment therapy; ACT) have begun to show promise in reducing IWB, but have not yet looked at this therapy in conjunction with a BWLP. Finally, there has also been a growing interest in and need for telehealth-based programs and interventions. The COVID19 pandemic demonstrated a clear need for efficacious telehealth programs, and a further benefit is that these programs may reach populations with limited access to resources (i.e., rural populations). Thus, the current study aims to examine a third-wave based IWB intervention paired with a standard BWLP delivered through video conferencing software.

- Primary Outcome Measures
Name Time Method Weight Change Baseline to Week 10 Weight Change
Weight Self-Stigma Questionnaire Baseline to Week 10 Internalized Weight Bias, which is internalizing weight bias towards oneself, is summed on a scale of 12 to 60, with higher scores indicating greater weight bias internalization. Includes two subscales of Self-Devaluation (WSSQ-SD) and Fear of Enacted Stigma (WSSQ-FNE), each summed on scale of 6-30.
Revised Morgenstern Physical Activity Questionnaire (PAQ-M) Baseline to Week 10 The Revised Morgenstern Physical Activity Questionnaire assesses Physical Activity through 11 items, asking participants specifically about light, moderate, or rigorous exercise, recreational activities, home, volunteer, or work activities, and chores.
Diet History Questionnaire III (DHQ III) Baseline to Week 10 The Diet History Questionnaire III assesses Eating Behavior, including various food items/groups (with 124 food items) and frequency and portion of each food item or group.
Weight Bias Internalization Scale Baseline to Week 10 Internalized Weight Bias, which is internalizing weight bias towards oneself, is scored on a scale of 1 to 7, with higher scores indicating greater weight bias internalization.
Three Factor Eating Questionnaire-R18 (TFEQ-18) Baseline to Week 10 The Three Factor Eating Questionnaire-R18 is an 18-item measure designed to examine eating behavior through three subscales: cognitive restraint, uncontrolled eating and emotional eating using a 4-point Likert scale, using "definitely true" to "definitely false". Higher scores indicate more disordered eating.
- Secondary Outcome Measures
Name Time Method The Eating Disorder Diagnostic Scale Baseline to Week 10 The Eating Disorder Diagnostic Scale - DSM 5 Version is 22-item a questionnaire designed to assess symptoms of anorexia nervosa, bulimia nervosa, and binge-eating disorder per DSM-5 criteria. The questions vary in terms of format, using 6-point Likert ratings from "Not at all" to "Extremely," dichotomous items and asking about frequency of diagnostically relevant behavior over a set period of time (i.e., days per week for over X amount of months)
Depression Anxiety and Stress Scale - 21 Items (DASS-21) Baseline to Week 10 The Depression Anxiety and Stress Scale assess depression, stress, anxiety, with score cut off's for...
* depression: normal: 0-9, mild: 10-12, moderate:13-20, severe: 21-27, and extremely severe: 28-42.
* anxiety: normal: 0-6, mild: 7-9, moderate: 10-14, severe:15-19, and extremely severe: 20-42.
* stress: normal: 0-10, mild:11-18, moderate:19-26, severe: 27-34, and extremely severe: 35-42.
Higher scores equate higher depression, anxiety, and stress.Rosenberg Self-Esteem Scale Baseline to Week 10 Self-Esteem will be measured utilizing the 10-item Rosenberg Self-Esteem Scale (RSES). The RSES uses a 4-point Likert scale from 1 (strongly disagree) to 4 (strongly agree), which higher scores indicating higher self-esteem.
The Acceptance and Action Questionnaire - Second Edition (AAQ-II) Baseline to Week 10 The Acceptance and Action Questionnaire is a 7-item questionnaire that uses a 7-point Likert scale from 1 (never true) to 7 (always true). Higher scores indicate less psychological flexibility and higher experiential avoidance.
Satisfaction with Therapist and Therapy Scale Baseline to Week 10 The Satisfaction with Therapist and Therapy Scale assesses satisfaction with therapy and therapist using a 5-point Likert scale, from 1 (Strongly Disagree) to 5 (Strongly Agree). Questions regarding treatment will be adapted for the telehealth, BWLP situation (i.e., "I am satisfied with the quality of the therapy I received" will be adapted to "I am satisfied with the quality of the telehealth weight loss treatment I received"). Similarly, questions about the therapist will be changed to "weight loss coach."
Ruminative Response Scale - Short Form Baseline to Week 10 The Ruminative Response Scale - Short Form includes nine items with two subscales; brooding and reflection. The form utilizes a 4-point Likert scale ranging from 1 ("almost never") to 4 ("almost always") for various aspects of rumination. Higher scores indicate more rumination.
Self-Compassion Scale Baseline to Week 10 The Self-Compassion Scale is a 12-item scale that uses a 5-point Likert scale ranging from 1 (almost never) to 5 (almost always). The scale has six subscales; the first three represent crucial/core components of self-compassion: self-kindness, common humanity, and mindfulness, and the remaining three serve as counters to these core components, with self-judgement, isolation, and overidentification (becoming wrapped up in negative emotions). The three core components are added together, along with reverse-scored counter components, to create an overall score in which higher scores indicate higher self-compassion.
Brief Stigmatizing Situations Inventory Baseline to Week 10 The Brief Stigmatizing Situations Inventory is a 10-item scale used to measure experiences of weight stigma, including items such as "Overhearing other people making rude remarks about you in public," on a Likert scale ranging from 0 (never) to 9 (daily), and higher scores indicating more situations encountered.
Universal Measure of Bias (UMB-FAT) Baseline to Week 10 The Universal Measure of Bias (UMB-FAT) is a 20-item scale that assesses attitudes towards fat, using a 7-point scale with "strongly agree" to "strongly disagree." It includes four subscales: negative judgment (dislike towards individuals with overweight or obesity), distance (comfort with individuals with overweight or obesity in social situations), equal rights (assessing the belief that individuals with overweight or obesity deserve legal protection against discrimination) and attraction (the extent to which the participant finds individuals with overweight or obesity to be attractive). Higher scores indicating greater weight bias by the participant.
