Factors Associated With Healthy Lifestyle Behaviors Among Adolescents

Objective: Guided by cognitive theory, this study tested an explanatory model for adolescents' beliefs, feelings, and healthy lifestyle behaviors and sex differences in these relationships. Methods: Structural equation modeling evaluated cross-sectional data from a healthy lifestyle program from 779 adolescents 14 through 17 years old. Results: Theoretical 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. Discussion: Findings 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.
