- Brief Summary
Investigators propose to conduct a pilot single-blind, parallel arm, randomized placebo-controlled trial evaluating the feasibility, acceptability, and preliminary efficacy of bright light therapy on reward system functioning among patients undergoing medication-assisted treatment for opioid use disorder.
- Detailed Description
Bright light therapy (BLT) is a simple, safe, and accessible intervention that can effectively ameliorates sleep disruptions, as well as circadian misalignment and depressive symptoms, and could potentially improve reward system function among patients with OUD. Beyond seasonal affective disorder, BLT has shown efficacy as an intervention for non-seasonal depression, and post-traumatic stress disorder, which all exhibit significant impairment of the dopaminergic reward system and poor sleep quality as key symptoms. Investigators propose to conduct a pilot single-blind, parallel arm, randomized placebo-controlled trial evaluating the feasibility, acceptability, and preliminary efficacy of BLT on reward system functioning among patients undergoing medication-assisted treatment for OUD. The present study will establish feasibility for a larger randomized-clinical trial proposal.

Group Intervention Description Dim light (placebo) group Wearable placebo light therapy device Participants will receive 30-minute dim light (placebo) therapy for 2 weeks. Participants will start the therapy within a few minutes of their designated wake up time, which is determined by their average wake time from the baseline week of sleep assessment. Bright light therapy group Wearable bright light therapy device Participants will receive 30-minute morning bright light therapy for 2 weeks. Participants will start the therapy within a few minutes of their designated wake up time, which is determined by their average wake time from the baseline week of sleep assessment.
- Primary Outcome Measures
Name Time Method Feasibility--adherence to intervention At 2 weeks post-treatment The number of days bright light therapy was completed divided by the total number of treatment days
Acceptability of the intervention At 2 weeks post-treatment It will be measured by the Global Satisfaction subscale in an adapted version of the Treatment Satisfaction Questionnaire for Medication. The scores are calculated for each of the subscales, which range from 0 to 100, with higher scores indicating higher patient satisfaction with the intervention.
Changes in reward valuation Baseline and 2 weeks post-treatment Delayed Discounting Task will be used to assess reward valuation
Feasibility--drop-out rate At 2 weeks post-treatment From enrollment to post-treatment assessment
Changes in reward learning Baseline and 2 weeks post-treatment Probabilistic Reward Task will be used to assess reward learning
Changes in Opioid Craving Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) To assess daily opioid craving, participants will be asked to rate the degree to which they have an urge to use illicit opioids in the moment on a 0-100 Visual Analogue Scale, with 0 being "Not at All" and 100 being "Extremely." This will be assessed multiple times per day via ecological momentary assessments. The timing of administration will be pseudo-randomized, but will broadly cover morning, midday and evening. Higher scores indicate greater opioid craving.
- Secondary Outcome Measures
Name Time Method Wake After Sleep Onset (WASO) Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) WASO is defined as the total number of minutes awake following sleep initiation and before participants get out of bed in the morning. WASO will be derived from wrist-worn actigraphy.
Positive Affect Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) To assess daily positive affect, participants will be asked to rate several adjectives that describe positive affect on a 5-point Likert scale, with 1 being "No" and 5 being "Extremely." Items are based upon the Positive and Negative Affect Schedule. Positive affect will be assessed multiple times per day via ecological momentary assessments. The timing of administration will be pseudo-randomized, but will broadly cover morning, midday and evening. Higher scores indicate greater positive affect.
Illicit Opioid Use Frequency Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) Illicit opioid use will be assessed multiple times per day via ecological momentary assessments. The timing of administration will be pseudo-randomized, but will broadly cover morning, midday and evening.
Total Sleep Time (TST) Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) TST is defined as the total number of minutes asleep between the time a participant goes to bed at night and the time a participant gets out of bed in the morning. Total Sleep Time will be derived from wrist-worn actigraphy.
Sleep Onset Latency (SOL) Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) SOL is defined as the duration of time from turning the light off to falling asleep. SOL will be derived from wrist-worn actigraphy.
Negative Affect Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) To assess daily negative affect, participants will be asked to rate several adjectives that describe negative affect on a 5-point Likert scale, with 1 being "No" and 5 being "Extremely." Items are based upon the Positive and Negative Affect Schedule. Negative affect will be assessed multiple times per day via ecological momentary assessments. The timing of administration will be pseudo-randomized, but will broadly cover morning, midday and evening. Higher scores indicate greater negative affect.
Sleep Efficiency (SE) Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks) SE is defined as sleep latency plus wake after sleep onset, and is calculated as the number of sleep minutes divided by the number of minutes in bed multiplied by 100. SE will be derived from wrist-worn actigraphy.
