Stice's dual pathway model of dietary restraint and negative affect was examined in both adolescent girls and boys. Self-report treasures assessing body dissatisfaction, dietary restraint, negative affect and bulimic behavior were administered to 267 girls and 199 boys aged between 12 and 16 years. The findings for the girls were consistent with Stice's model, in that they indicated that both dietary restraint and negative affect mediated the relationship between body dissatisfaction and bulimic behavior. For the boys who desired a thinner body size, only negative affect was found to mediate the relationship between body dissatisfaction and bulimic behavior. On the other hand, for boys who desired a larger body size, both body dissatisfaction and dietary restraint were found to exert an independent effect on bulimic behavior. As boys can aspire to two contrasting and seemingly opposite body size ideals, the findings highlight that the relationship between body dissatisfaction, dietary restraint, negative affect and bulimic behavior are more complex in males than in females. Further research using longitudinal designs is needed in order to test the directional and bidirectional nature of the observed interrelationships. (C) 2001 Elsevier Science Ltd. All rights reserved.
