The Theory of Planned Behavior (TPB)
The TPB is a well-researched intention model that has been successful for use in
predicting and explaining behavior across a wide variety of domains. According
to the TPB, purchase behavior is determined by purchase intention, which is, in
turn, determined by subjective norms, perceived behavioral control, and attitude
(Ajzen, 1991). The links among subjective norms, perceived behavioral control,
and attitude toward purchases have been fully examined with various products
(e.g., Alfadl, Ibrahim, & Hassali, 2012; Jirotmontree, 2013; Yoon, 2011), but not
with sporting goods.
