The purpose of this research was to examine whether pedometer ownership and source of pedometer (i.e., self-purchased, a gift, a promotion) was related to physical activity self-efficacy and outcome expectations in relation to physical activity. Further, the authors examined whether there was a relationship between pedometer ownership and pedometer source and leisure-time physical activity (LTPA) and walking behavior. The authors also observed the possible role of sociodemographic variables, including gender, age, socioeconomic status, and education in these relationships. Results of the study showed that although pedometer ownership may be related to self-efficacy and outcome expectations in relation to LTPA, it is not directly associated with higher LTPA levels or walking. Further, men who bought their pedometers indicated greater coping self-efficacy than those who received them in a promotion. (Contains 1 table.)
