Abstract
The purpose of this study was to explore whether sedentary behavior cognitions explain
physical activity (PA) intention and behavior when integrated within the theory of
planned behavior framework (TPB). A random community sample of 206 adults and
a sample of 174 undergraduate students completed measures of the TPB pertaining to PA
and four popular leisure-time behaviors (TV viewing, computer use, sedentary hobbies,
and sedentary socializing) and an adapted Godin Leisure-Time Exercize Questionnaire
(community sample ¼ cross-sectional, undergraduate sample ¼ 2-week prospective).
Results using ordinary least squares regression provided evidence that TV viewing
intention explains additional variance in PA behavior, and affective attitude (community
sample) and perceived behavioral control (undergraduate sample) towards TV viewing
explains additional variance in PA intention even after controlling for PA-related TPB
constructs. These results underscore the potential value of adding sedentary control
interventions in concert with PA promotion.
