The aims of the current study were to assess the factor structure of w
eight loss expectancy and to explain weight reduction behavior among t
eenagers. An anonymous questionnaire was administered to a sample of 5
99 adolescents. Principal components analysis identified four weight l
oss expectancy factors, which were labeled social confidence, adult ap
proval, self-worth, and negative consequences. Results from regression
analyses indicated that dieting frequency, diet pill use, and purging
were best explained by different subsets of predictors. Overall, self
-esteem, gender, and specific expectancy and knowledge variables accou
nted for most of the variance in measures of dieting frequency, diet p
ill use, and purging. The findings suggest that weight management educ
ation for teenagers should emphasize self-esteem enhancement. However,
curriculum planning must also address the anticipated psychosocial re
wards of weight loss and attend to gender-specific concerns.
