Alcohol Use Disorder (AUD) and insomnia are both more prevalent among Veterans than in the general population. While insomnia is 3-9 times more prevalent in AUD than in the general population, patients with comorbid AUD and insomnia suffer from higher severity of AUD with increased alcohol craving, reduced quality of life, impaired interpersonal functioning, higher risks for suicidal behavior and relapse during early abstinence. There are limited options to treat drinking behavior and insomnia due to side effect profile (disulfiram). Medications commonly used to treat pathological drinking and promote abstinence include Naltrexone and Topiramate. However, these medications do not improve insomnia. Furthermore, hypnotic medication treatments with trazodone, gabapentin, and ramelteon have shown variable impact for sleep disturbance and abstinence. By contrast, all four studies evaluating Cognitive Behavioral Therapy for Insomnia (CBT-I) have shown a large magnitude of effect for treating insomnia but with minimal to no effect on abstinence. Thus, combining MED and CBT-I will improve their insomnia and bolster their recovery. This combination treatment will be the first personalized intervention in treating Veterans with AUD and comorbid insomnia.

A sample of treatment-seeking Veterans with AUD (N=82) will be initially treated with a medication for drinking (MED), that will be either TOP 200 mg a day for six weeks, naltrexone 50 mg daily (and up to 100 mg daily), depot-naltrexone 380 mg injections every 4 weeks, or a combination of TOP + NTX. They will stabilized on the MED over 6 weeks and then randomized to receive either CBT-I (N=41) or Sleep Hygiene Education (SHE, a behavioral placebo intervention) (N=41) weekly for the next eight weeks. The investigators will conduct CBT-I following the standard protocol using 30-minute sessions to deliver its components (Sleep Restriction, Stimulus Control, Sleep Hygiene and Cognitive Therapy). A post-intervention visit will be conducted eight weeks after the end of the intervention phase. The primary outcome measure will be the the insomnia severity (as assessed using the Insomnia Severity Index). The secondary outcome measure will include the Percent Days Abstinent (as computed from the Time Line Follow Back interview). The investigators will also track other aspects of alcohol use, sleep and daily functioning using TLFB, PACS, sleep diaries, BDI, and the STAI to test whether successful treatment of drinking and insomnia will be associated with better clinical outcomes in AUD. It is hypothesized that in Veterans with AUD, the combination of MED+CBT-I, as compared to MED+SHE group, will lead to superior sleep-related outcomes along with pre-post treatment effect sizes comparable to the meta-analytic norms. On an exploratory basis, the MED + CBT-I arm will have a relatively higher percentage of days abstinent from alcohol and the improvement in insomnia and abstinence from drinking will show durability eight weeks after end of behavioral sleep treatment. If these hypotheses are supported, the findings will need to be validated in a larger multi-center trial. If validated, the findings would support: 1) including insomnia treatment as a standard component of the initial protocol for treating AUD comorbid with insomnia, and 2) using MED+CBT-I combination treatment to manage this subpopulation of AUD patients.
