The first two sessions will occur at the beginning of the study. These initial sessions will focus on effective behavioral strategies to enhance sleep time, including goal setting (e.g., bedtimes and wake-up times), problem-solving and preplanning, stimulus control (i.e., sleep hygiene recommendations), and positive reinforcement.
