The effects of monitoring and feedback on compliance

A two-group randomized experimental design was employed to assess the effects of monitoring and feedback on the compliance of 93 psychiatric outpatients treated with lithium. Compliance in both groups was measured using self-report, lithium level, appointment-keeping, and medication refill frequency. The experimental group was also monitored using a unique electronic device that records the time and day pills are removed. At the midpoint of the study, the experimental group received feedback about serum lithium levels and patterns of removing medications from the monitoring device while the control group received feedback about serum lithium levels only. The study demonstrated no sustained effect of the monitoring and feedback interventions on compliance.
