Substance Use and Mental Health Severity Among LGBTQ Individuals Attending Minnesota Model-Based Residential Treatment

This administrative data analysis examined substance use and mental health severity among a sample of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) individuals receiving residential treatment for an alcohol or drug use disorder. LGBTQ were statistically compared to heterosexual patients on a number of variables, including frequency and amount of pretreatment alcohol use, frequency of pretreatment illicit drug use, co-occurring Axis I mental health diagnoses, and past history of physical or sexual abuse. LGBTQ patients exhibited significantly greater severity on nearly all variables, suggesting a strong relationship between clinical severity and being a sexual minority. This study also found a relationship between patient gender and the pattern of differences between LGBTQ and heterosexual patients. These results replicate and extend those of studies examining LGBTQ in the general population and suggest opportunities for development of alcohol/drug treatment approaches that address the unique needs of LGBTQ.
