Insights
This study adapted an eating disorder prevention program for pregnant individuals, showing high satisfaction and improved body image. The adapted intervention shows promise for perinatal mental health.
Area of Science:
- Implementation Science
- Perinatal Mental Health
- Eating Disorder Prevention
Background:
- The perinatal period presents significant risks for body dissatisfaction and disordered eating.
- Existing evidence-based disordered eating interventions require adaptation for pregnant populations.
- This study focused on adapting the Body Project, an established eating disorder prevention program.
Purpose of the Study:
- To adapt the Body Project intervention for pregnant individuals with a history of disordered eating.
- To utilize the ADAPT framework to guide intervention adaptation.
- To assess the feasibility and acceptability of the adapted intervention through a pilot trial.
Main Methods:
- The Body Project was adapted using the ADAPT framework, needs assessment, and stakeholder input.
- A pilot trial was conducted with 10 previously pregnant individuals with a history of disordered eating.
- Participant feedback was gathered via surveys and a focus group, analyzed using the Consolidated Framework for Implementation Research (CFIR).
Main Results:
- 80% of participants attended at least five of the six sessions.
- Average satisfaction ratings were high (9.28/10).
- 89% reported improved body satisfaction, and 33% reduced disordered eating behaviors.
Conclusions:
- An empirically supported eating disorder prevention program was successfully adapted for pregnant individuals.
- Adaptation decisions balanced intervention fidelity, scalability, and participant feedback.
- The adapted intervention will be formally tested in a future randomized controlled trial.
Background:
The perinatal period is a high-risk time for body dissatisfaction and disordered eating. Evidence-based interventions for disordered eating have not been adapted to address the needs of this population. We describe the process of adapting the Body Project, an evidence-based eating disorder (ED) prevention program, for pregnant individuals with histories of disordered eating behaviors.
Method:
Our approach is informed by ADAPT, a framework offering guidance for adapting interventions to new contexts, to modify the Body Project for pregnant individuals. Following initial adaptations informed by a needs assessment and stakeholder input, we conducted a pilot trial with individuals who have lived experience relative to our target population (i.e., previously pregnant individuals with ED history, n = 10). Participants provided feedback on the intervention through surveys and a focus group assessing perceptions of the intervention and barriers and facilitators to its implementation as guided by the Consolidated Framework for Implementation Research (CFIR).
Results:
Eighty percent of enrolled participants attended five or more sessions (out of six). Across sessions, average satisfaction ratings were 9.28 (1 = poor to 10 = excellent). Most participants (89%) reported improvements in body satisfaction. Approximately 33% reported reductions in disordered eating with the remainder reporting no change due to healthy eating behaviors at baseline. Themes from the focus group are reported aligning with CFIR domains and all final modifications are summarized and reported aligning with the Framework for Reporting Adaptation and Modifications-Enhanced.
Conclusions:
Applying implementation science frameworks to structure our process for making and summarizing planned adaptations, we adapted an empirically supported ED prevention program for pregnant individuals with histories of an ED. We made adaptation decisions based on participant feedback while weighing intervention fidelity and scalability. We will formally test the adapted intervention in a subsequent pilot randomized controlled trial versus a time- and dose-matched educational control.
