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.

Outcome Measures
Primary Outcomes (6)
Feasibility--drop-out rate
From enrollment to post-treatment assessment
At 2 weeks post-treatment
Feasibility--adherence to intervention
The number of days bright light therapy was completed divided by the total number of treatment days
At 2 weeks post-treatment
Acceptability of the intervention
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.
At 2 weeks post-treatment
Changes in reward learning
Probabilistic Reward Task will be used to assess reward learning
Baseline and 2 weeks post-treatment
Changes in reward valuation
Delayed Discounting Task will be used to assess reward valuation
Baseline and 2 weeks post-treatment
Changes in Opioid Craving
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.
Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks)
Secondary Outcomes (7)
Total Sleep Time (TST)
Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks)
Sleep Onset Latency (SOL)
Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks)
Wake After Sleep Onset (WASO)
Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks)
Sleep Efficiency (SE)
Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks)
Illicit Opioid Use Frequency
Daily for the 1 week at baseline and throughout the treatment period (up to 2 weeks)
- +2 more secondary outcomes
Study Arms (2)
Bright light therapy group
EXPERIMENTALParticipants 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.
Dim light (placebo) group
PLACEBO COMPARATORParticipants 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.
Interventions
Light treatment glasses (Re-timer®) will be used to deliver bright light therapy. This device is available commercially and allows participants to freely move around while receiving light from LEDs positioned below the eyes. Re-timer® can be worn over glasses and does not interfere with vision, reading, or computer work.
The placebo Re-timer® emits light intensity to a level that will not impact sleep and circadian timing and appears identical to the original Re-timer®.
