title: Validity of cognitive predictors of adolescent sugar snack consumption.
abstract: 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.
  
  
  METHODS
  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%.
  
  
  CONCLUSIONS
  When applied to consumption of sugared snacks among Ugandan adolescents, the TPB shows satisfactory validity.
