Abstract
Translating the dietary knowledge among individuals into healthy behavior remains a
challenging task. This study examines the causal relationship between dietary knowledge and
behavior by including self-efficacy in the models.
A series of regression models were developed based on Baron and Kenny (1986) to assess
whether self-efficacy mediated the link between the predictor variables and dietary behavior.
Regression analyses supported the hypothesized relationships that self-efficacy mediates effects
of dietary knowledge and social influences on dietary behavior. Self-efficacy also accounted for
variance in eating behavior not explained by knowledge or demographic variables.
