Brief Summary

The primary aim of the present research project is to examine the feasibility, as measured by treatment perceptions, and tolerability, as measured by adherence and attrition, of two weeks of flashed light therapy alone followed by four weeks of daily flashed light therapy combined with four weekly videoconference-delivered cognitive behavioral therapy sessions targeting circadian rhythms and sleep in four adolescents aged 14 to 17 years with attention-deficit/hyperactivity disorder and delayed sleep-wake schedules.

Outcome Measures

Primary Outcomes (4)

  • Treatment Feasibility: Child-reported

    Child rating of how acceptable they find the treatment to be on a scale from 1 (very unacceptable) to 7 (very acceptable).

    7 weeks

  • Treatment Feasibility: Parent-reported

    Parent rating of how acceptable they find the treatment to be on a scale from 1 (very unacceptable) to 7 (very acceptable).

    7 weeks

  • Treatment Tolerability: Treatment Adherence

    The number of days the participant was exposed to morning light therapy per self-report tracker.

    7 weeks

  • Treatment Tolerability: Attrition

    The number of participants who withdrew from the study out of the total cases enrolled.

Study Arms (1)

1) Flashed Light Therapy, 2) Flashed Light Therapy with Cognitive Behavioral Therapy

EXPERIMENTAL

Treatment Phase 1 (2 weeks duration): light flashes administered for 60 minutes daily beginning 75 minutes prior to the participant's average morning wake time and ending 15 minutes before average morning wake time. Treatment Phase 2 (4 weeks duration): will begin immediately following phase 1 and involve daily light flashes (as described above) combined with weekly 50-minute videoconference-delivered cognitive-behavioral therapy.

Device: Flashed Light TherapyBehavioral: Videoconference-delivered Cognitive Behavioral Therapy

Interventions

Light flashes will be presented over 60 minutes as 3-millilisecond flashes of white light at 4,000 lux every 20 seconds

Also known as: Light flashes
1) Flashed Light Therapy, 2) Flashed Light Therapy with Cognitive Behavioral Therapy

Treatment will involve psychoeducation on sleep, circadian rhythms and light exposure, motivational interviewing, advancing of bedtime schedule, time management and coping with poor sleep, sleep hygiene, stimulus control, sleep restriction, and cognitive restructuring for worry.
