Testing an Internet-Based Intervention for Preventing Eating Disorders

Approximately 2% to 4% of college-aged women suffer from eating disorders (EDs), and many
more are at risk of developing them. A previous Internet-based intervention called Student
Bodies (SB), which focused on body image concerns, was effective in reducing risk factors
for EDs among college-aged women. However, the original SB program did not account for
certain other risk factors, such as depression and compensatory behaviors like self-induced
vomiting, over-exercising, or use of diuretics. Image and Mood (IaM) is an enhanced version
of the SB program and takes into account depressive symptoms and the use of compensatory
behaviors. This study will examine whether IaM will reduce ED risk factors in a large
population of college women who are at high risk of developing EDs.

Participation in this study will last 10 weeks. Participants will be randomly assigned to
either receive the IaM program or be placed on a wait list. The IaM program, which will be
delivered through the Internet, will provide information about nutrition, exercise, body
image, and coping skills—including examples and exercises. It will also include an online
message board monitored by a study psychologist. Each week the IaM participants will monitor
their behavior, keep a journal about their experiences, and answer self-report
questionnaires. Assessments of eating disorder symptoms; weight and shape concerns;
depressive symptoms; and incidence of substance abuse, anxiety, or depressive disorders will
be completed post-treatment and at 1- and 1.5-month follow-ups. Those assigned to the wait
list will complete these assessments and then receive the IaM program after the last
follow-up.
