Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participation in this study will last 2 years and will involve both parent and daughter participants. Study participation for parent participants will include three 15-minute interviews conducted at baseline and Years 1 and 2. The interviews will focus on their daughters' social adjustment, performance in school, relationships with others, hobbies, and related topics. Daughter participants will still be allowed to partake in the study even if their parents do not complete all three interviews.
All potential daughter participants will first complete a 20-minute interview regarding their eating habits and mental health. Eligible participants will then be assigned to one of three programs designed to improve body image satisfaction:
* Program 1 will consist of the distribution of an educational brochure about a healthy body image.
* Program 2 will involve four 1-hour meetings during which participants will complete a series of verbal and written exercises. The exercises will aim to increase body image satisfaction by helping participants to think critically about the thin ideal and to discuss some of the problems associated with the pursuit of this ideal.
* Program 3 will include eight 1-hour meetings during which participants will also complete a series of verbal and written exercises. The exercises will aim to increase body image satisfaction by helping participants to think critically about the thin ideal and by promoting healthy eating and exercise habits.
Participants in all programs will complete brief surveys and interviews about their attitudes and behaviors at baseline, at treatment completion, and at three other points during the 2 years from baseline.
