Objective:
The purpose of the current study was to evaluate the effectiveness of a life-skills promotion program designed to improve body image satisfaction and global self-esteem, while reducing negative eating attitudes and behaviors and feelings of perfectionism, all of which have been identified as predisposing factors to disordered eating.
Method:
A total of 258 girls with a mean age of 11.8 years (intervention group = 182 and control group = 76) completed questionnaires before, and 1 week after, the six-session school-based program, and again 6 and 12 months later.
Results:
The intervention was successful in improving body image satisfaction and global self-esteem and in reducing dieting attitude scores at post intervention only. The gains were not maintained at the 12-month follow-up.
Discussion:
The need to assess the influence of health promotion programs on predisposing risk factors, compared with problem-based outcome measures, is discussed.
