The purpose of this study was to determine the effects of an 8week intervention program based on the Traustheoretical Model (Prochaska and DiClemente, 1983) on physical activity levels and stage of exercise behavior in high school girls. A second purpose was to analyze changes in determinants, barriers, and values following the intervention program. The participants were 57 female high school students (M age = 15). Participants were divided into control and experimental groups. All participants completed pre- and posttests that measured physical activity, stages of exercise behavior, values, barriers, and determinants. The experimental group received an 8-week physical activity intervention program between the pre- and posttests. The intervention included a physical activity counseling component based on the processes from the Transtheoretical Model along with workouts designed to be repeated as leisure time physical activities. The control group received no treatment between the pre- and posttests. MANCOVA w ere performed on all variables. It was found that physical activity was significantly different between the experimental and control groups from the pre- to the posttest at p [less than] .05. There was also a significant difference in the stage of exercise behavior between the control and experimental group participants at p [less than] . …
