- Detailed Description
The investigators aim to conduct a feasibility randomized controlled trial (RCT) of an eating disorder prevention program (The Body Project, adapted for pregnancy) versus a health education control among pregnant individuals with histories of an ED. The investigators will test the feasibility, implementation outcomes, and its preliminary effectiveness in reducing the risk of elevated disordered eating and body dissatisfaction during pregnancy and postpartum.
The investigators will aim to recruit N=60 pregnant individuals (in their first or second trimester) with histories of an ED. Both the intervention and active control consist of 6, weekly, 1-hour group sessions (6-8 participants per group) delivered over Zoom. There are four assessment points: pre-intervention, post-intervention, 3 months postpartum, and 6 months postpartum. Participants will complete online surveys at each assessment point and a post-intervention exit interview (active intervention only).

- Primary Outcome Measures
Name Time Method Feasibility of recruitment 0 weeks The investigators will consider the program feasible if the investigators meet recruitment targets (N=60).
Session attendance 6 weeks The investigators will assess what percentage of enrolled participants complete 4 or more sessions. The benchmark will be \> 50% of participants will complete 4 or more sessions.
Drop Out 6 weeks The investigators will assess what percentage of enrolled participants complete post-test assessments. The benchmark will be \> 50% of participants will complete the post-test surveys and interviews.
Client satisfaction questionnaire (CSQ-8) 6 weeks Assesses participants' satisfaction with the intervention. Scores range from 8 to 32 with higher scores indicating greater satisfaction. The benchmark will be that at least 70% of participants will have scores over and above the midpoint in both the PBP and PHE groups.
Credibility and Expectancy Questionnaire (CEQ) 0 weeks Assesses participants' perceptions that the treatment will work after learning about the study. The first three items measure credibility, and the latter three items measure expectancy. It is scored on a scale of 3-27 with higher scores indicating greater confidence in the treatment. The benchmark will be that at least 70% of participants will have scores over and above the midpoint in both the PBP and PHE groups.
Feasibility of data collection Through the study completion, approximately 1 year depend on gestational at enrollment E.g.: The investigators will assess the feasibility of quantitative measures with the benchmark of no questionnaires fully missing in \>25% of participants
Adapted Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), & Feasibility of Intervention Measure 6 weeks Assesses acceptability, appropriateness, and feasibility of the intervention and Facilitators and Barriers to Participating. Acceptability, appropriateness, and feasibility subscales each consist of 4 items ranging from 1-5. Scores can be calculated by averaging the 4 items and range from 1-5. Higher scores indicate greater acceptability, appropriateness, and feasibility. The benchmark will be that at least 70% of participants will have scores over and above the midpoint for these subscales in both the PBP and PHE groups. Facilitators and Barriers to participating are open-ended questions and will be assessed with qualitative analyses.
Facilitator Adherence to Sessions Through the study completion, approximately 1 year depend on gestational at enrollment The investigators will assess the percentage of sessions with ≥75% adherence. The benchmark will be ≥70% of sessions will have ≥75% adherence (checklist and audio recordings); 20% of sessions rated.
Participant Adherence to Homework 6 weeks The investigators will assess the percentage of participants that complete (i.e., upload/submit) ≥75% of the homework assignments. The benchmark will be ≥70% of participants will complete ≥75% of the homework assignments.
- Secondary Outcome Measures
Name Time Method Thin Ideal Internalization Scale 0 weeks, 6 weeks, 3 months pp, 6 months pp Measures the degree to which a person identifies with the notion that thinness is equivalent to attractiveness, with items ranging from 1-5. Scores are calculated by averaging the 8 items, and range from 1-5, with higher scores indicating greater internalization of the thin ideal.
Dutch Restrained Eating Scale 0 weeks, 6 weeks, 3 months pp, 6 months pp Measures the frequency of dieting behaviors, with items ranging from 1-5. Scores are calculated by averaging the 10 items, and range from 1-5, with higher scores indicating increased levels of restrictive eating.
The Satisfaction and Dissatisfaction with Body Parts Scale 0 weeks, 6 weeks, 3 months pp, 6 months pp Measures body dissatisfaction, with items ranging from 1-5. Scores are calculated by averaging the 9 items, and range from 1-5, with higher scores indicating greater body dissatisfaction.
Body Image in Pregnancy Scale (BIPS) 0 weeks, 6 weeks, 3 months pp, 6 months pp 36 items that measure body image during pregnancy, with items ranging from 1-5. The measure is made up of seven subscales: 'preoccupation with physical appearance' (six items), 'dissatisfaction with facial features' (four items), 'sexual attractiveness' (six items), 'prioritizing appearance over body functioning' (five items), 'appearance-related behavioral avoidance' (three items), and 'dissatisfaction with body parts' (six items). Subscale scores are calculated by averaging items, and range from 1-5, with higher scores indicating greater body image disturbance. The investigators adapted wording to administer the questionnaire again during postpartum.
Eating Disorder Examination Questionnaire (EDEQ) 0 weeks, 6 weeks, 3 months pp, 6 months pp 28-item questionnaire measuring ED psychopathology, with items ranging from 0-6. A global score is obtained by averaging all items except for 13-18, with higher scores indicating increased ED symptoms. The clinical cut-off score is 2.8, which indicates a probable ED. Items 13-18 assess frequency of ED behaviors and are not included in the global score.
Prenatal Eating Behaviors Screening (PEBS) 0 weeks, 6 weeks, 3 months pp, 6 months pp Measures ED psychopathology during pregnancy, with items ranging from 1-5. Scores are calculated by summing the 12 items, and range from 12-60, with higher scores indicating greater ED symptomatology during pregnancy. Scores \>39 indicate a current ED.
Intuitive Eating Scale-3 (IES-3) 0 weeks, 6 weeks, 3 months pp, 6 months pp Measures intuitive eating, with items ranging from 1-5. A global score can be calculated by averaging the 12 items, and range from 1-5, with higher scores indicating greater levels of intuitive eating. Subscales (Unconditional Permission to Eat, Eating for Physical Reasons, Reliance on Hunger and Satiety Cues, and Body-Food Choice Congruence) can be calculated by averaging items specific to each subscale.
Eating Disorder Diagnostic Scale (EDDS) 0 weeks, 6 weeks, 3 months pp, 6 months pp Provides tentative diagnoses of full threshold anorexia nervosa, full threshold bulimia nervosa, full threshold binge eating disorder, subthreshold anorexia nervosa, subthreshold bulimia nervosa, and subthreshold binge eating disorder. The EDDS also generates an overall ED symptom score based on the sum of all relevant items. Higher scores indicate increased disorder eating symptomology with a clinical cut-off score of 16.5 for the overall symptom composite score (Krabbenborg et al., 2011).
