Brief summary

The goal of this clinical trial is to test two behavioral treatments for nightmares in adults with narcolepsy. The main questions it aims to answer are: * Is imagery rehearsal therapy (IRT) effective for narcolepsy-related nightmares? * Does adding targeted dream control (TDC) to IRT make it more effective? Participants will be randomized to one of two treatment groups and will be asked to: * Complete a daily log of sleep symptoms for up to 13 weeks. * Attend 7 sessions of treatment. * Complete questionnaires before and after treatment. * Go to the research lab in Evanston, IL to complete a sleep study during a daytime nap (Chicago area residents only).

Interventions

Therapy to reduce nightmares, delivered via videoconference sessions

BEHAVIORALTargeted dream control

Therapy to reduce nightmares, delivered in videoconference sessions and lab session. Lab session will involve a sleep study during a daytime nap.

Design outcomes

Primary

MeasureTime frameDescription
Nightmare FrequencyBaseline (assessed daily for 2 or 4 weeks) and posttreatment (assessed daily for 2 weeks beginning in week 9 or 11)Frequency of nightmares as measured by daily diary
Disturbing Dream and Nightmare Severity ScaleBaseline and posttreatment (up to 13 weeks)Measures nightmare severity. Minimum = 0, maximum = 37. Higher scores represent a worse severity of nightmares.

Secondary

MeasureTime frameDescription
Patient Reported Outcomes Measurement Information System (PROMIS) Anxiety ScaleBaseline and posttreatment (up to 13 weeks)Measures symptoms using Computer Adaptive Testing (CAT) with higher scores reflecting more anxiety symptoms (worse outcome). Population mean (T-score) of 50 with a standard deviation of 10.
Patient Reported Outcomes Measurement Information System (PROMIS) Depression ScaleBaseline and posttreatment (up to 13 weeks)Measures symptoms using Computer Adaptive Testing (CAT) with higher scores reflecting more depressive symptoms (worse outcome). Population mean (T-score) of 50 with a standard deviation of 10.
