Detailed Description

The goal of this project is to develop guidelines for the clinical tailoring of Cognitive Behavioral Therapy for Insomnia (CBT-I) for Veterans with psychotic disorders and insomnia, and to test the acceptability, feasibility, and preliminary efficacy of CBT-I for improving sleep-related functional outcomes in this population.

Specific Aim 1: Develop empirically-derived guidelines for the clinical tailoring of CBT-I materials and procedures for Veterans with psychotic disorders through an iterative process with input from Veteran clients, CBT-I experts and providers, as well as those with expertise in psychotic disorders.

Specific Aim 2: Establish the acceptability of CBT-I for Veterans with psychotic disorders and insomnia when delivered using guidelines developed in Specific Aim 1 in order to make further refinements to the guidelines in a preliminary trial with 6 Veterans with psychosis and insomnia.

Specific Aim 3: Conduct a randomized controlled trial (n=60) to test the feasibility and preliminary efficacy of CBT-I in producing positive changes at post-treatment and 3-month follow-up on the outcomes of insomnia symptoms, sleep quality, and functioning.

Arm && Interventions

Group	Intervention	Description
Cognitive Behavioral Therapy-Insomnia	Cognitive Behavioral Therapy-Insomnia	CBT-I addresses cognitive, arousal and behavioral factors related to sleep difficulties. Sessions combine assessment, conceptualization, psychoeducation, behavioral strategies and cognitive therapy, using a consistent structure including review of participants' sleep log and adherence to behavioral guidelines, modification of time in bed, cognitive therapy, and relaxation techniques. CBT-I also incorporates psychoeducation about biological and psychological elements that regulate sleep. Other strategies include stimulus control (i.e., getting out of bed when not sleepy) to extinguish the conditioned arousal common in insomnia, and relaxation techniques to reduce arousal associated with the bed, bedroom, or bedtime.
Health and Wellness	Health and Wellness	Health and Wellness is a general self-management curriculum focused on providing education and support for managing physical and emotional well-being. Each session follows a basic structure including review of previous session material, new educational information and discussion on several topics over the course of single or multiple sessions. Each session will focus on the impact of the topic on overall health and wellness, identifying benefits and challenges to improving or maintaining health in that area, and strategies that clients may find helpful to address challenges in that area. Example topics include physical activity/exercise, nutrition/healthy eating, managing medications and side effects, and addictive behaviors (e.g., substance use, gambling, eating).

Primary Outcome Measures

Name	Time	Method
Insomnia Severity Index (ISI)	Participants will be assessed following completion of the study intervention, an expected average of 10 weeks.	ISI score; scored on a scale of 0 to 28, with higher scores indicating worse insomnia severity.

Secondary Outcome Measures

Name	Time	Method
Veterans RAND 36-Item Health Survey Mental Component Score	Participants will be assessed a second time following completion of the study intervention, an expected average of 22 weeks.	Veterans RAND 36-Item Health Survey Mental Component Score; Possible scores range from 0 to 100, with higher scores indicating greater mental health quality of life.
Insomnia Severity Index (ISI)	Participants will be assessed a second time following completion of the study intervention, an expected average of 22 weeks.	ISI score; scored on a scale of 0 to 28, with higher scores indicating worse insomnia severity.
World Health Organization Disability Assessment Schedule (WHO-DAS), Participation in Society Subscale	Participants will be assessed a second time following completion of study intervention, an estimated average of 22 weeks.	WHO-DAS score; scores range from 0 to 100 where 100 is full disability.
