The current study aims to test a third-wave based IWB intervention paired with a standard BWLP delivered through video conferencing software.
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.

ACT-based programs and self-compassion have shown promise throughout research for lowering IWB (Berman et al., 2016; Levin et al., 2018; Lillis et al., 2009; Palmeira, Cunha, \& Pinto-Gouveia, 2017; Palmeira, Pinto-Gouveia, \& Cunha, 2017; Forbes et al., 2020). Therefore, using techniques from prior ACT- and self-compassion based programs, a weight bias reduction intervention will be administered. Session topics will include psychoeducation and coping for weight bias and internal weight bias, and these topics will be viewed through a self-compassionate and ACT-based lens (for example, participants may defuse from internal critical thoughts rather than challenge them). Sessions will also cover acceptance, cognitive defusion, mindfulness, committed action, and the dialectical behavioral therapy (DBT) DEARMAN skill.

Weight Bias Internalization Scale
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.
Time frame: Baseline to Week 10
Weight Self-Stigma Questionnaire
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.
Time frame: Baseline to Week 10
Revised Morgenstern Physical Activity Questionnaire (PAQ-M)
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.
Time frame: Baseline to Week 10
Diet History Questionnaire III (DHQ III)
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.
Time frame: Baseline to Week 10
Three Factor Eating Questionnaire-R18 (TFEQ-18)
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.

Self-Compassion Scale
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.
Time frame: Baseline to Week 10
Brief Stigmatizing Situations Inventory
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.
Time frame: Baseline to Week 10
Depression Anxiety and Stress Scale - 21 Items (DASS-21)
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.
Time frame: Baseline to Week 10
Rosenberg Self-Esteem Scale
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.
Time frame: Baseline to Week 10
The Acceptance and Action Questionnaire - Second Edition (AAQ-II)
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.
Time frame: Baseline to Week 10
Satisfaction with Therapist and Therapy Scale
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."
Time frame: Baseline to Week 10
Ruminative Response Scale - Short Form
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.
Time frame: Baseline to Week 10
Universal Measure of Bias (UMB-FAT)
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.
Time frame: Baseline to Week 10
The Eating Disorder Diagnostic Scale
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)
