Testing the Feasibility and Preliminary Effects of a Six-week Online Program, "Calm Sleep Coaching", in Adults With Sleep Disturbance

The Centers for Disease Control and Prevention has identified insufficient sleep as a public health epidemic, with more than 70 million US adults experiencing insomnia each year. However, access to current evidence-based interventions for sleep disturbance (e.g., Cognitive Behavior Therapy for Insomnia [CBT-I]) is limited due to the need for specialized providers as well as monetary and logistical barriers that prevent many individuals from attending in-person treatment sessions (e.g., scheduling, transportation, childcare). Novel modes of delivery are needed to extend the benefits of these treatments to a wider range of individuals in need.

For many individuals, digital intervention platforms may serve as an attractive alternative to receiving treatment and health services that are otherwise difficult to access. The Calm app is a consumer-based meditation smartphone app that is easy to use, inexpensive, and widely accessible (currently over 3.1 million paying subscribers). Recent surveys (N=12,151; N=11,210) indicate that between 76 and 89% of the Calm app subscribers were experiencing sleep difficulties when they downloaded the app, and 63-76% downloaded the Calm app specifically to improve their sleep. Given the Calm apps popularity and the need for techniques to improve sleep, leveraging the Calm apps existing platform will allow for efficient dissemination of a digital sleep intervention (i.e., Calm Sleep Coaching).

The Calm app has developed a new 6-week online sleep-coaching school (Calm Sleep Coaching) to improve the quality and quantity of sleep for individuals who complete the program. The development of Calm Sleep Coaching was informed by evidence-based techniques (e.g., CBTi, mindfulness practices, Self-Determination Theory, and Social Cognitive Theory). However, the feasibility and effectiveness of Calm Sleep Coaching has not yet been evaluated.

Therefore, the purpose of this study is to evaluate Calm Sleep Coaching in adults with sleep disturbance (score of greater than or equal to 8 on the Insomnia Severity Index) by 1) determining the feasibility (i.e., acceptability, demand) of Calm Sleep Coaching and 2) determining the preliminary effects of Calm Sleep Coaching on primary (sleep quality) and secondary outcomes (i.e., symptoms of insomnia, mental health, well-being, resilience, and productivity). Investigators also aim to explore coaches' experiences with implementation of Calm Sleep Coaching using an investigator developed survey and assess the participants stage of change (transtheoretical model) throughout the program. Investigators hypothesize that 1) Calm Sleep Coaching will be feasible among individuals with sleep disturbance and 2) participating in the Calm Sleep Coaching program is associated with improvements in primary and secondary outcomes compared to the control group (with greater improvements observed among those participating in higher touch coaching interventions).

Investigators aim to recruit N=200 participants. Participants will be randomized into one of four groups: 1) High-touch intervention (N=50; real-time video and chat messaging, coach response via live videos), 2) medium-touch intervention (N=50; real-time video and pre-recorded video and chat messaging with response from coach), 3) low-touch intervention (N=50; chat messaging with response from coach), or 4) Sleep education control (N=50; no coaching).
