Abstract
OBJECTIVE: To examine differences in the processes of change and self-efficacy for exercise across the stages of change in 3 populations to determine its suitability for use in diverse groups. METHODS: Cross-sectional survey design with population as a between-subjects variable: high school students (n = 168), university undergraduate students (n = 215), and employed adults (n = 63). RESULTS: ANOVAs revealed main effects of stage (p < .0001) and population (p < .001) in process use and self-efficacy but no population by stage interaction. CONCLUSIONS: The consistency of patterns of the TTM variables supports its potential for effective intervention in diverse populations.
