Abstract
The present quasi-experimental study examined an electronically delivered, stage-matched intervention aimed at promoting physical activity levels and enhancing psychological determinants of physical activity behavior among Korean adults. A total of 378 administrative staff participated in this study, which was delivered electronically at Seoul National University of Technology (South Korea) over 16 consecutive weeks. At baseline, week 8, and week 16, participants completed measures of stage of change, processes of change, decisional balance, self-efficacy, and physical activity behavior. Data were analyzed using frequency analysis and repeated measures MANOVA. Significant improvements were observed for stage of readiness for change, physical activity behavior, physical activity self-efficacy, pros, and the use of the cognitive and behavioral processes of change, with significant decreases in their cons for being physically active. To our knowledge, this is the first study to fully employ the transtheoretical model of behavior change as an organizing framework with the program being delivered using an emerging intervention technology (i.e., e-mail) among Korean adults employed at a single worksite. Preliminary support was found for this intervention modality within a non-western sample.
