About

Cognitive behavioral therapy (CBT-I) is a common treatment for insomnia that does not use medications. While CBT-I is effective for insomnia, it does not tend to improve the waking symptom of fatigue. Another treatment, Bright Light Therapy, is used for treating seasonal depression and sleep disorders, and may improve fatigue and physical activity in individuals with PAH. The purpose of this study to assess the effects of Bright Light Therapy compared to CBT-I to treat insomnia and fatigue in patients with PAH.

Full description

In a single site, 3-arm (Cognitive Behavioral Therapy [CBT-I] group; Bright Light Therapy group; Standard of Care group), parallel, randomized controlled trial we will enroll 36 subjects (n=12 per group) to assess the feasibility of Bright Light Therapy compared to CBT-I in subjects with pulmonary arterial hypertension (PAH) to treat insomnia (difficulty initiating sleep or maintaining sleep) and fatigue.

• To assess the recruitment and retention rates of CBT-I and Bright Light Therapy.
• To compare the effects of CBT-I and Bright Light Therapy to Standard of Care on (insomnia and fatigue severity) and secondary (wake after sleep onset and sleep onset latency) outcomes.
• To test the effects of CBT-I and Bright Light Therapy to Standard of Care on the secondary outcome physical activity.
• To test the effects of CBT-I and Bright Light Therapy to Standard of Care on the secondary outcomes: depression, dyspnea and QOL.

6 participants in 3 patient groups

Cognitive Behavioral Therapy-Insomnia (CBT-I)

Experimental group

Description:

CBT-I treatment will receive 1 session every week, for 8 weeks (8 total sessions). The CBT-I sessions will be provided by a pool of clinical PhD psychology students by a trained professional. Each visit will be conducted via telehealth. Sessions will include discussions regarding such topics as sleep restriction, stimulus control and sleep hygiene. Review of sleep diaries will occur during the sessions.

Treatment:

Behavioral: CBT-I

Bright Light Therapy

Experimental group

Description:

Bright Light treatment will consist of 8 weeks of daily use of the Re-timer device. The Re-timer is worn like a pair of glasses and contains light emitting diodes mounted on the lower portion of the frame. The Re-timer emits blue-green 500 nm light with an intensity of \~500 lux lm/m2. Subjects will be instructed to use the device for 30 minutes within two hours of waking, in the morning on the full brightness setting.

Treatment:

Device: Bright Light Therapy

Standard Care

No Intervention group

Description:

Subjects will continue the care they routinely receive.
