Multimodal Sleep Intervention Using Wearable Technology

Targeting sleep concerns may be a novel strategy for reducing increased risk of alcohol use
disorders in young adults. The current study will develop and test a mobile intervention
addressing sleep concerns in 120 heavy-drinking young adults. All participants will wear
sleep and alcohol trackers daily. Participants will be randomized to one of three
interventions. The primary intervention (60 participants) will include web-based sleep
hygiene advice + sleep/alcohol diary self-monitoring + sleep/alcohol data feedback. The
comparison interventions will be compared to matched control conditions only including these
components: (1) web-based sleep hygiene advice (30 participants) or (2) web-based sleep
hygiene advice + sleep/alcohol diary self-monitoring (30 participants). The primary objective
is to evaluate sleep intervention component feasibility, acceptability, and preliminary
efficacy on alcohol outcomes to inform a Stage II randomized trial comparing the final sleep
intervention with a standard alcohol intervention.

Inclusion Criteria:

1. 18-25 years of age;

2. report ≥ 3 heavy drinking occasions in the last 2 weeks (i.e., ≥5 drinks on 1 occasion
for men; ≥4 for women);

3. report having concerns about their sleep;

4. willing/able to complete daily sleep diaries and wear sleep and alcohol trackers;

5. report Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) scores
indicative of risk of harm from drinking (i.e., ≥7 and ≥5 for men and women,
respectively)

6. read and understand English;

7. have a smartphone that can be used to sync tracker data. An estimated 86% of young
adults own a smartphone.

Exclusion Criteria:

1. history of a sleep disorder;

2. night or rotating shift work; travel beyond 2 time zones in month prior and/or planned
travel beyond 2 time zones during study participation;

3. meet criteria for an alcohol use disorder in the past 12 months that is clinically
severe defined by: a) a history of seizures, delirium, or hallucinations during
alcohol withdrawal; b) report drinking to avoid withdrawal symptoms or have had prior
treatment of alcohol withdrawal; c) have required medical treatment of alcohol
withdrawal in the past 6 months;

4. currently enrolled in alcohol or sleep treatment;

5. exhibit current psychiatric illness (i.e., bipolar disorder, schizophrenia, major
depression, panic disorder, borderline personality disorder, organic mood or mental
disorders, or suicide or violence risk) by history or psychological examination;

6. current DSM-V substance use disorder or a positive urine drug screen for opiates,
cocaine, barbiturates, benzodiazepines, amphetamines, or phencyclidine.
