SCT seems to be useful in understanding factors associated with physical exercise, with self-efficacy and goals being the strongest predictors.

Discuss

Unmeasured socio-structural, environmental, and personal variables could contribute to an increase of SCT’s explanation of variance in physical activity behaviour.

More About

Your Topic

SCT's conceptualisation has led to a variation in the model constructs’ operational definitions as well as usage of a wide variety of tools to measure those
