N2 - Objective: The Theory of Planned Behaviour (TPB) and the Transtheoretical Model of Change (TTM) outline the proximal determinants of exercise. This study compared their predictive utility in relation to exercise among young Chinese people in Hong Kong. Design and Sample: A prospective study of 1067 high school pupils selected by stratified random sampling, 572 of who were followed up at 6 months. Measures: Measures of the TPB, the TTM, exercise behaviour and demographic data were obtained. Results: The TPB was a significant, but weak, predictor of exercise behaviour. Of the TPB variables, perceived behavioural control (PBC) was the strongest predictor of behaviour. However, past exercise was the strongest predictor of future exercise behaviour. The TTM variables were poor predictors of movement between stages of change. The TTM was a stronger predictor than the TPB of stage of change, whereas the TPB was a stronger predictor of exercise behaviour. Conclusions: The TPB and the TTM are relevant to understanding factors related to exercise in young Chinese people. The TPB is a significant, but weak, predictor of exercise behaviour. Cross-sectional support for the TTM is good, although longitudinal support is modest. PBC, intentions, self-efficacy and behavioural processes are strongest predictors of movement between stages.
