Abstract

The Theory of Planned Behavior (TPB), the Health Belief Model (HBM), and a modified HBM including intention were compared in their ability to predict dieting and fasting. Female university students (n = 373) completed a survey assessing variables from the TPB and the HBM. Three months later, a subsample reported subsequent weight loss behaviors. The TPB predictor model explained 35% of the variance in follow-up dieting and 67% in intention. The HBM model explained 29% of the variance in follow-up dieting and the modified HBM model explained 38% of the variance in follow-up dieting and 57% in intention.. The TPB model for fasting explained 14.5% of the variance in follow-up fasting and 58% in intention. The modified HBM model explained 19% of the variance in follow-up fasting and 41% in intention. Results show all models were able to predict a significant portion in the variance of dieting and fasting follow-up behavior; however the variance explained in follow-up fasting increased when intention was added to the HBM model. Attitude measures were the strongest predictors of behavioural intention and intention was the strongest predictor of follow-up dieting and fasting in the TPB and modified HBM models. Theoretical and clinical implications are discussed.
