INTRODUCTION: We previously developed a brief, behavioral intervention (Sleep Promotion Program, SPP) that demonstrated feasibility, acceptability, and increased self-reported sleep. Here, we tested the effects of SPP on the trial's secondary outcomes: sleep duration, regularity, and timing as measured by actigraphy and conducted a secondary analysis of SPP's effects on rest-activity rhythms.
METHODS: Forty participants (ages 13-15) with insufficient and irregular sleep randomized to SPP-continuation (n = 22), or to sleep monitoring-SPP (n = 18), had analyzable actigraphy data. SPP included sleep psychoeducation and one individual clinician session. Participants wore an actigraph for 1-2 weeks during baseline, Period 1, and Period 2. We hypothesized SPP would lead to longer and more regular sleep from baseline to Period 1 compared to sleep monitoring that would be sustained at Period 2. We used multilevel models with a treatment by time interaction to test whether SPP improved sleep relative to sleep monitoring. We also compared sleep changes from Period 1 to Period 2 among participants randomized to SPP-continuation.
RESULTS: Participants receiving SPP decreased the difference in weekend-weekday sleep onset by 54-minute (β = 1.1; p = .03) from baseline to Period 1 (i.e., increased regularity). Increased regularity was maintained at Period 2. Total sleep time did not change significantly.
CONCLUSION: SPP regularized weekend-weekday sleep onset timing in adolescents with insufficient and irregular sleep but did not change actigraphic sleep duration, which differed from increases in self-reported sleep duration previously reported. Regularizing sleep may be an attainable first step to improving adolescent sleep. Future work is needed to test whether sleep regularity predicts adolescent health outcomes.
