A sleep promotion program for insufficient sleep among adolescents: a pilot feasibility randomized controlled trial.

Study objectives: To examine the feasibility, acceptability, and impact of a Sleep Promotion Program (SPP).

Methods: This pilot trial randomized adolescents (13-15y) with insufficient sleep duration and irregular sleep timing to SPP-continuation (n=24; SPP in month 1, continuation treatment in month 2) or monitoring-SPP (n=20; monitoring in month 1, SPP in month 2). SPP included one clinician session and at-home delivery of web-based reports of each youth's sleep diary data with accompanying intervention questions that prompt youth to engage in sleep behavior change. Attrition rate primarily measured feasibility. Program satisfaction measured acceptability. Total sleep time (TST), sleep timing, and sleep timing regularity were measured via sleep diary at baseline, follow-up 1, and follow-up 2 (each ∼1 month apart). Linear mixed effects models compared treatment arms on changes in sleep from baseline to follow-up 1 (month 1). We also compared changes in sleep during month 1 to changes in sleep during month 2 among SPP-continuation participants.

Results: Attrition rate was 8.5%. 96.5% participants rated the quality of care received as good or excellent. In month 1, SPP-continuation youth showed a significantly greater increase in mean TST than monitoring-SPP youth (0.57 vs. -0.38 hours; contrast=0.95; CI=0.14, 1.76, p=0.024). SPP-continuation participants showed an increase in TST during month 1 (0.51h) but a decrease during month 2 (-0.74 h; contrast=-1.24, CI=-2.06, -0.42, p=0.005). No other significant effects were observed.

Conclusions: SPP is highly feasible, acceptable, and associated with a significant increase in TST early in treatment.
