An Evaluation of a Personal Electronic Device to Enhance Self-Monitoring Adherence in a Pediatric Weight Management Program using a Multiple Baseline Design

Objective To examine the effectiveness of a personal electronic device (PED) in order to improve adherence to self-monitoring of dietary intake and physical activity. Method The impact of a PED on adherence to self-monitoring goals was examined in a multiple baseline design across three overweight adolescents. During baseline, a traditional paper-and-pencil method of self-monitoring was utilized. The subsequent study phase introduced a PED for self-monitoring. Percent self-monitoring goal attainment was the outcome of interest. Results During baseline, attainment of self-monitoring goals was low for all three participants (3-4%). Each subject's percent attainment of self-monitoring goal increased upon the introduction of the PED. For two of the three subjects this increase was stable (similar to 75 and 100%) post-intervention. For the third subject the increase in percent attainment of self-monitoring goal was more variable but remained above baseline levels. Conclusion PEDs have potential for improving self-monitoring in the context of behavioral weight management treatment for adolescents.
