A Comparison of Opioid and Nonopioid Substance Users in Residential Treatment for Co-Occurring Substance Use and Mental Disorders.

The past decade has seen a marked increase in the illicit use of opioids, as well as a doubling of the percentage of individuals seeking treatment for opioid use disorders. However, little is known about the differences between opioid users and nonopioid users in residential treatment. Further, no studies have been published that compare opioid users and nonopioid users in treatment for co-occurring substance use and mental disorders. To address this gap, this study examined differences between opioid and nonopioid substance users in residential treatment for co-occurring disorders. Data was drawn from 1,972 individuals treated between 2009 and 2011 at one of three private residential treatment centers that provide integrated treatment for co-occurring substance use and mental disorders. Data was collected at program intake, and 1- and 6-month postdischarge using the Addiction Severity Index and the University of Rhode Island Change Assessment. To examine within-group changes in substance use, addiction severity, and mental health across time, linear mixed-model analyses were conducted with facility, year, age, gender, and race included as covariates. The authors found more similarities than differences between the two groups on baseline characteristics, treatment motivation, length of stay, and outcomes on measures of substance use, addiction severity, and mental health. The results demonstrate that though opioid users entered treatment with higher levels of substance use-related impairment, they were just as successful in treatment outcomes as their non-opioid-using peers.

Differences between older and younger adults in residential treatment for co-occurring disorders.

OBJECTIVE: The purpose of this study was to examine differences between older and younger adults who received integrated treatment for co-occurring substance use and mental disorders, including differences on demographic and baseline characteristics (e.g., substance use, readiness for change, mental health symptoms, and severity of problems associated with substance use), as well as predictors of retention in treatment. METHODS: This study included 1400 adults who received integrated substance abuse and mental health treatment services at one of two private residential facilities offering residential and outpatient services. Initial analyses consisted of basic descriptive and bivariate analyses to examine differences between older (≥ 50 years old) and younger (< 50 years old) adults on baseline variables. Next, three ordinary least squares regression models were employed to examine the influence of baseline characteristics on length of stay. RESULTS: Three main findings emerged. First, older adults differed from younger adults on pre-treatment characteristics. Older adults used more alcohol and experienced greater problem severity in the medical and alcohol domains, while younger adults used more illicit drugs (e.g., heroin, marijuana, and cocaine) and experienced problems in the drug, legal, and family/social domains. Second, while readiness to change did not differ between groups at baseline, older adults remained enrolled in treatment for a shorter period of time (nearly four days on average) than younger adults. Third, the pattern of variables that influenced length of stay in treatment for older adults differed from that of younger adults. Treatment retention for older adults was most influenced by internal factors, like psychological symptoms and problems, while younger adults seemed influenced primarily by external factors, like drug use, employment difficulties, and readiness for change. CONCLUSIONS: The results of this study add to the limited knowledge base regarding older adults receiving integrated treatment for co-occurring substance use and mental health disorders by documenting that age-based differences exist in general and in the factors that are associated with the length of stay in residential treatment.
