Introduction A preliminary study showed the existence of a relationship between alcohol craving and insomnia symptoms. The current investigation aimed to further assess the relationship between obsessive and compulsive qualities of alcohol craving and insomnia disorder in a larger sample of subjects with Alcohol Use Disorder (AUD) seeking treatment for their drinking. Methods We used baseline cross-sectional data from a clinical trial of treatment-seeking patients with AUD (N=123). We used the following instruments: Insomnia Severity Index (ISI) total score for insomnia; Obsessive Compulsive Drinking Scale (OCDS) scale scores for alcohol craving; Time-Line follow Back interview for computing the number of drinks per drinking day within the past 90 days; Hamilton Anxiety Rating Scale total score for the anxiety symptoms; and Addiction Severity Index for demographic variables. We used bivariate analysis to evaluate whether alcohol craving outcome measures (OCDS subscale scores and total score) were independently associated with the ISI total score. A multivariable model adjusted for sociodemographic and clinical covariates further evaluated this relationship between OCDS and ISI total scores. Results The mean (SD) age was 44.02 (10.37) years with 13.29 (3.10) years of education, 83.74% were males, 41.80% identified themselves as White, 17.21% were married, and 56.09% were employed. In a bivariate analysis, ISI total score was associated with the obsessive subscale (β=0.25, p
