Outcome Measures

Primary Outcomes (6)

• Weight Change

  Weight Change

  Baseline to Week 10

• 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.

  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.

  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.

  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.

  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.

  Baseline to Week 10

Secondary Outcomes (9)

• Self-Compassion Scale

  Baseline to Week 10

• Brief Stigmatizing Situations Inventory

  Baseline to Week 10

• Depression Anxiety and Stress Scale - 21 Items (DASS-21)

  Baseline to Week 10

• Rosenberg Self-Esteem Scale

  Baseline to Week 10

• The Acceptance and Action Questionnaire - Second Edition (AAQ-II)

  Baseline to Week 10

Interventions

Internalized Weight Bias Intervention BEHAVIORAL

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.
