A stage-matched intervention for exercise behavior change based on the transtheoretical model.
The effectiveness of a stage-matched intervention for enhancing exercise behavior was investigated with related Transtheoretical Model constructs among young Korean adults. 265 university students (147 men, 118 women; M age=24.1 yr., SD=3.5) enrolled in Seoul National University of Technology voluntarily participated in an 8-wk. intervention study. In order to measure exercise behavior and its related psychological constructs, the Stages of Readiness for Exercise Behavior Scale, Decision Balance Scale for Exercise, Exercise Self-efficacy Scale, Processes of Change Scale, and Leisure Time Exercise Questionnaire were used. Results indicated that the participants' exercise readiness was significantly changed in a positive way after the 8-wk. intervention. There was a significant main effect of testing time and an interaction between testing time and exercise readiness stage at baseline. There were significant interactions between testing times and groups for all Transtheoretical Model measures, implying that the stage-matched intervention can be an effective tool for increasing exercise readiness and related psychological variables. The present study provides a starting point for stage-matched interventions aimed at increasing exercise levels, and a baseline level from which to evaluate interventions.
