摘要：

Objective: To estimate the applicability of an extended version of the theory of planned behavior (TPB) in predicting self-perceived sugar intake among adolescents in Uganda. Method. Two questionnaires were completed involving 1146 and 372 secondary school adolescents. Confirmatory factor and path analyses were performed using Amos software. Results: TPB exhibited good fit with the data (chi(2)= 1.29, df=2, P=0.53) and ex-plained 58% and 5% of the variance in intention and self-perceived behavior. Adding past behavior increased the explained variance of behavior with 4%. Conclusion: When applied to consumption of sugared snacks among Ugandan adolescents, the TPB shows satisfactory validity.
