Social cognitive determinants of moderate and vigorous physical activity in college freshmen

This paper examined the relationship among social cognitive factors and physical activity in college freshmen. Students from a midwestern university (N = 69; 56.5% female) participated in this prospective study. Psychosocial data were collected at the beginning of a semester, and physical activity measurement by accelerometry was completed at semester's end. Multiple regression analyses indicated that self-efficacy and physical activity goals were significant predictors of vigorous activity (r ² =.16). However, these constructs were not significant for moderate activity (r ² =.16). Social cognitive constructs appear to be related to vigorous, but not moderate activity in college freshmen. Future studies should consider assessing social cognitive and physical activity variables at multiple time points across extended durations.
