Abstract
ObjectiveGuided by cognitive theory, this study tested an explanatory model for adolescents' beliefs, feelings, and healthy lifestyle behaviors and sex differences in these relationships. MethodsStructural equation modeling evaluated cross-sectional data from a healthy lifestyle program from 779 adolescents 14 through 17 years old. ResultsTheoretical relationships among thoughts, feelings, and behaviors were confirmed and sex differences identified. Thoughts had a direct effect on feelings and an indirect effect through feelings on healthy behaviors for both sexes. A direct effect from thoughts to behaviors existed for males only. DiscussionFindings provide strong support for the thinking–feeling–behaving triangle for adolescents. To promote healthy lifestyle behaviors in adolescents, interventions should incorporate cognitive behavioral skills–building activities, strengthening healthy lifestyle beliefs, and enhancing positive health behaviors.
