Brief summary
This study explores how daily physical activity affects sleep in people recovering from substance use disorders (SUD). Sleep problems are common during and after treatment for SUD and can make recovery harder. While physical activity is known to improve sleep in other populations, little is known about how it impacts sleep in people with SUD—especially over time and at different stages of recovery. We will follow people in three groups: those currently in residential treatment, those in ongoing recovery programs, and those in long-term recovery (over one year). Participants will wear activity and sleep monitoring devices and complete short daily surveys for one month. This will help us understand how day-to-day changes in physical activity relate to sleep and overall wellbeing. We will also compare two different sleep tracking devices to see how well they agree. The findings will provide a better understanding of how physical activity supports recovery, and may help tailor future treatments to each person’s unique needs.
Interventions
This observational study uses an n-of-1 design to investigate the natural relationship between physical activity and sleep quality over 30 consecutive days. Participants represent three stages of substance use disorder (SUD) recovery: (1) individuals beginning residential treatment, (2) those transitioning into continuing care (after around six months of treatment), and (3) individuals in long-term (more than one year) recovery living in the community. Participants will wear a thigh-mounted physical activity monitor (SENS Motion) throughout the study period. Sleep will be assessed using the same device and, for groups 2 and 3 (and optionally for group 1), also using an under-mattress sensor (Withings Sleep Analyzer) for 30 consecutive nights. The Withings Sleep Analyzer features a thermoplastic polyurethane pad filled with air and linked to a pressure sensor. It is placed under the mattress, beneath the participant’s torso, and detects pressure changes within the air bladder relative to atmospheric pressure. Data will be collected automatically and linked to an app on the study iPads (group 1) or participants’ mobile phones (groups 2 and 3). In addition, participants will complete brief daily self-report surveys via ecological momentary assessment (EMA) once each evening for 30 days. The survey will be delivered through Qualtrics. Participants in group 1 will complete the surveys using study iPads distributed at the residential facility, while participants in groups 2 and 3 will receive survey links via SMS to their mobile phones each evening. These repeated measurements aim to track daily fluctuations and investigate how changes in physical activity may relate to sleep outcomes within and between individuals.
