What this Trial Is About
Researchers are evaluating a sleep health program designed specifically for U.S. Marine Corps personnel to see if it can improve sleep quality, duration, and overall mental health. The study focuses on whether the program can reduce symptoms of depression, anxiety, PTSD, suicidality, and suicide ideation. This research addresses the urgent need for effective sleep-focused interventions in military settings, as poor sleep is a known risk factor for suicide and psychological distress among service members. The study involves five groups of participants who will receive different combinations of three sleep health programs: Sleep Leadership training for officers and senior enlisted Marines, the CLASS-MC educational program adapted for Marines, and the Insomnia Coach mobile app based on cognitive behavioral therapy for insomnia. Group 1 receives all components, while Groups 2, 3, and 4 receive various combinations, and Group 5 serves as a delayed treatment comparison. The interventions include classroom sessions, in-person presentations, and app-based activities delivered over several weeks. Participants will complete surveys at baseline, immediately post-intervention, and at 6, 12, and 24 weeks after starting the study. A subset will also use wearable sleep-tracking devices to monitor sleep patterns. Researchers will measure changes in sleep quality, depression symptoms, anxiety, PTSD symptoms, suicidality, and other sleep-related behaviors. The study lasts about 24 weeks per participant, with assessments to track psychological and sleep health improvements over time.
