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 (chi2 = 1.29, df = 2, P = 0.53) and explained 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.
