The objectives of the of this pilot study were two-fold: (a) to establish a valid baseline pedometer step count for young adolescents, and (b) to determine the impact of self regulation strategies on daily pedometer use. To establish a valid baseline step count, seventh and eighth-grade students (n=66) from a local junior high school volunteered to wear sealed pedometers throughout each day for one week. Associated classroom teachers recorded step counts and resealed the pedometer each day. Cronbach alpha values (α =.786) based on a four-day recording period were high. Volunteers from all seventh and eighth-grade physical education classes (n=113; 52 females, 61 males) in the same local junior high school participated in a five-week pilot study to determine the impact of self regulation strategies on weekly pedometer use. After a four-day baseline collection period, participants were placed into one of three groups based on convenience of class periods taught by two physical education teachers: (a) Self Regulation group participants (n= 43) wore a non-sealed pedometer and individually charted daily step counts; (b) Open Group participants (n=34) wore a non-sealed pedometer and reported daily steps counts on a piece of paper turned in each day; (c) Control Group participants (n= 36) wore a sealed pedometer for the entire recording period. At baseline, there were no significant step-count differences between the three groups (F(2,110) = 1.553, p .216). Average baseline step counts equaled 11,124 ± 3150.72 steps for girls and13,673 ± 3745.24 steps for boys. A repeated measures mixed model analysis of variance was used to determine differences between groups each week. Preliminary results revealed significant differences between Groups (F(2,111)=5.996, p= .003), Weeks (F(3,294)=7.621, p= .000), and the interaction between Groups and Weeks (F (6,294)=2.644, p=.016). Since the interaction value represents mean steps for any given group at any given week, interpretation of the interaction is difficult. It appears that the Self Regulation group did experience a positive effect on the interaction based on reported higher step counts compared to the Control group for all four weeks, and the Open group during week two. In conclusion, it appears that self regulation strategies are beneficial to increase overall daily pedometer step counts, especially when used during the first two weeks of a program.
