NCT06659354

Brief Summary

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.

Outcome Measures

Primary Outcomes (9)

  • Feasibility of recruitment

    The investigators will consider the program feasible if the investigators meet recruitment targets (N=60).

    0 weeks

  • Session attendance

    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.

    6 weeks

  • Drop Out

    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.

    6 weeks

  • Client satisfaction questionnaire (CSQ-8)

    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.

    6 weeks

  • Credibility and Expectancy Questionnaire (CEQ)

    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.

    0 weeks

  • Feasibility of data collection

    E.g.: The investigators will assess the feasibility of quantitative measures with the benchmark of no questionnaires fully missing in \>25% of participants

    Through the study completion, approximately 1 year depend on gestational at enrollment

  • Adapted Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), & Feasibility of Intervention Measure

    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.

    6 weeks

  • Facilitator Adherence to Sessions

    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.

    Through the study completion, approximately 1 year depend on gestational at enrollment

  • Participant Adherence to Homework

    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.

    6 weeks

  • +9 more secondary outcomes

Study Arms (2)

Pregnant Body Project (PBP)

EXPERIMENTAL

The Body Project is typically delivered as four 1-hour weekly sessions consisting of written, verbal, and behavioral exercises. The sessions aim to induce cognitive dissonance by encouraging participants to challenge the thin-ideal, a theoretically and empirically supported component of ED prevention. This adapted version of the Body Project (the Pregnant Body Project; PBP) consists of 6 1-hour, weekly group sessions delivered via Zoom. Since the target population consists of individuals with histories of an ED or disordered eating behaviors, PBP also includes elements from a treatment intervention (i.e., the Body Project Treatment 8.0 manual). PBP was adapted iteratively with a needs assessment, expert stakeholder input, and participant feedback following a mock trial with individuals with lived experience (i.e., individuals with histories of an ED who have given birth). This condition will be peer-delivered by facilitators with lived experience.

Behavioral: Pregnant Body Project (PBP)

Pregnancy Health Education (PHE)

PLACEBO COMPARATOR

This time- dose- and attention- matched control condition accounts for the potential effects of time spent and support from group members and facilitators. Participants assigned to the PHE group will also be asked to attend 6, 1-hour, weekly group sessions via Zoom. During the sessions participants receive psychoeducation on body image and disordered eating during pregnancy but will not engage in any dissonance-inducing exercises. Participants will also receive lifestyle education specific to pregnancy (e.g., proper nutrition, sleep, physical activity), tied back to body image and disordered eating.
