The purpose of this study was to examine the effect of a 3-Day Physical Activity Recall (3DPAR) intervention program on the physical activity (PA) levels of rural Appalachian school youth. To the best of our knowledge, this is the first study in which the pre- and postlevel of PA in rural Appalachian school youth has been assessed following a 3DPAR intervention program. A sample of 76 school youth (Mage = 13.3 years) recruited from three secondary schools in the Appalachian region was included in the final analyses. To assess intervention effects such as steps per day and moderate to vigorous PA (MVPA) minutes per day, we had participants wear sealed NL-1000 piezoelectric pedometers for 7 days at pre- and posttest. For this 3-week pilot intervention, participants recorded daily activity using a 3DPAR self-report instrument. Participants received two educational sessions during the first three classes of the intervention period. We utilized a MANOVA to determine the effects of intervention participation on pre- versus posttest for the whole week, weekdays, and weekends. Youth who completed the 3DPAR-delivered intervention significantly increased their step counts on the weekends. Future studies should evaluate whether a longer intervention including a control group could result in improving PA over the long term.
