Abstract

Background: Although sexual minority women (SMW) are at increased risk of hazardous drinking (HD), efforts to validate HD measures have yet to focus on this population. Objectives: Validation of a 13-item Hazardous Drinking Index (HDI) in a large sample of SMW. Methods: Data were from 700 adult SMW (age 18-82) enrolled in the Chicago Health and Life Experiences of Women study. Criterion measures included counts of depressive symptoms and post-traumatic stress disorder (PTSD) symptoms, average daily and 30-day ethanol consumption, risky sexual behavior, and Diagnostic and Statistical Manual (DSM-IV) measures of alcohol abuse/dependence. Analyses included assessment of internal consistency, construction of receiver operating characteristic (ROC) curves to predict alcohol abuse/dependence, and correlations between HDI and criterion measures. We compared the psychometric properties (diagnostic accuracy and correlates of hazardous drinking) of the HDI to the commonly used CAGE instrument. Results: KR-20 reliability for the HDI was 0.80, compared to 0.74 for the CAGE. Predictive accuracy, as measured by the area under the receiver operating characteristic curve for alcohol abuse/dependence, was HDI: 0.89; CAGE: 0.84. The HDI evidenced the best predictive efficacy and tradeoff between sensitivity and specificity. Results supported the concurrent validity of the HDI measure. Conclusions: The Hazardous Drinking Index is a reliable and valid measure of hazardous drinking for sexual minority women. [ABSTRACT FROM AUTHOR]

23. Substance Use and Treatment Needs among Homeless Persons in Cook County, Illinois

Author

Johnson, Timothy and Barrett, Mark

Abstract

A survey of 481 homeless persons in Cook County, Illinois, was conducted to assess the prevalence of alcohol and illicit drug use in this population, and potential treatment needs. Respondents were sampled at random in emergency and transitional shelters, soup kitchens, drop-in centers, and single room occupancy (SRO) hotels. Approximately 30% were characterized as having alcohol-related treatment needs. A slightly smaller proportion (26.7%) were estimated to have treatment needs associated with drug use behavior, and 13.5% were found to have both alcohol and drug-related, or dual, treatment needs. Those with alcohol user treatment needs were mostly male, age 35 and older, White, and living in SRO hotels. In contrast, persons with drug user treatment needs were most likely male, under age 35, African-American, and found in shelter settings. Implications for the treatment of homeless persons with substance misuse problems are discussed.
