The Theory of Planned Behavior as a model for understanding sedentary behavior

The utility of a protection motivation theory framework for understanding sedentary behavior

“…In a recent study by Prapavessis, Gaston, and DeJesus (2015), findings revealed the tenability of a five factor TPB model, consistent with the theory. Other main findings include TPB items explaining 9-58% of the variance in intention with subjective norms being the strongest predictor, as well as 8-43% of the variance in behavior with intentions being the strongest predictor.…”

“…Items were rated on the same scale as the Sedentary Behavior Questionnaire (SBQ; Rosenberg et al, 2010) with extended responses (i.e. 10 h, 11 h, 12 h … 18 h) similar to the intention items from the TPB questionnaire (Prapavessis et al, 2015). A sample item was, "How much time do you expect to spend sitting over the next week."…”

“…Thus, the stem of the SBQ (" … how much time did you spend doing the following this past week") matched the time frame of goal intention and implementation intention (" … over the past week"). The same modifications Prapavessis et al (2015) made to the SBQ (i.e. addition of three items, expended response items) were also employed in the current study.…”

“…In light of Prapavessis et al's (2015) findings, it is likely that social-cognitive theories other than the TPB have the potential to enhance our understanding of sedentarism. The PMT is one of the major health psychology theories that has proven useful for gaining a better understanding of the conscious processes underlying the adoption of health-related behaviors such as physical activity (Plotnikoff et al, 2010).…”

“…University students represent an ideal population for studying sedentary behavior and cognitions for several reasons. First, research has shown that undergraduate students report high levels of sedentariness, averaging more than 12 hours of sedentary behavior per day (Prapavessis et al, 2015). Second, the transition to university is a life event associated with a steep decrease in physical activity among young men and women (Kwan, Cairney, Faulkner, & Pullenayegum, 2012).…”
