Research supports the utility of the Transtheoretical Model (TTM) in explaining individual level physical activity behavior. However, there remains an interest in examining constructs beyond the individual level. The predisposing, reinforcing, and enabling factors from the PRECEDE/PROCEED model fall within a broader educational and organizational diagnosis level and might be useful adjuncts to the explanatory power of TTM's constructs. Also, most of the TTM and PRECEDE/PROCEED research has been conducted in North American and other Eurocentric countries, however the models are being recommended for wide scale international dissemination. This study's purpose was to examine college students' physical activity behavior in both Korea (n = 228) and the United States (n = 189) on the basis of TTM and the PRE constructs. Standardized self-report instruments were completed in the participants' native language following a series of cross-cultural equivalency translations. The main variables of interest were age, body mass index, nationality, gender, weekly exercise behavior, behavioral and cognitive processes of change (α = .86 and .80, respectively), decisional balance (α = .59 Pros and .70 Cons), self-efficacy (α = .87), stage of change, and the predisposing (α = 86), reinforcing (α = .85), and enabling (α = .76) factors. The stage of change distribution for the entire sample was Precontemplation (n = 8), Contemplation (n = 27), Preparation (n = 128), Action (n = 35), and Maintenance (n = 203). In a stepwise discriminant function analysis, only 3 of the 12 predictors contributed to the participants' stage of change classification. In order of entry they were the behavioral processes of change (&Lambda; = .709, p < .001), weekly exercise behavior (&Lambda; = .574, p < .001), and gender (&Lambda; = .550, p < .001). Using these variables, and proportional to group size, participants in all the stages of change could be distinguished from one-another (p < .01) in a manner consistent with theoretical predictions. The overall stage of change classification accuracy was 66.8%, which was significantly greater than chance (p < .0001, contingency coefficient = .43). The most reliably classified stages of change were Precontemplation (62.5%), Preparation (68.8%), and Maintenance (86.2%). Given no particularly substantive nationality differences, the discussion will primarily focus on the internal and external validity of TTM and PRE, especially in reference to the behavioral processes of change, weekly exercise behavior, and gender.
