| Abstract: | ObjectivesHabit has been proposed as an explanation of why prior behavior is a good predictor of later behavior. This study examined whether habit mediates the relationship between prior and later physical activity (PA), within the framework of the attitude-social influences-efficacy (ASE) model and the theory of planned behavior (TPB).DesignA longitudinal design was used.MethodsA total of 1976 older adults completed questionnaires on ASE/TPB constructs and PA at baseline, intention at three months, habit at six months, and PA at twelve months.ResultsPath analyses showed that habit significantly mediates the relationship between prior and later PA, after ASE/TPB variables were taken into account.ConclusionsHabit is a partial solution to the question why prior PA is a good predictor of later PA. It is recommended to incorporate habit into the ASE/TPB model. |
