Persistence/recurrence of and remission from DSM-5 substance use disorders in the United States: Substance-specific and substance-aggregated correlates.

This study examined demographic and psychosocial correlates associated with persistence/recurrence of and remission from at least one of ten DSM-5 substance use disorders (SUDs) and three substance-specific SUDs (i.e., alcohol, cannabis, and prescription opioids). Data were collected from structured diagnostic interviews and national prevalence estimates were derived from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions. An estimated 25.4% of the U.S. population had at least one prior-to-past-year (prior) SUD. Among individuals with any prior SUDs, the prevalence of past-year substance use and DSM-5 symptomology was as follows: abstinence (14.2%), asymptomatic use (36.9%), symptomatic use (10.9%), and persistent/recurrent SUD (38.1%). Among individuals with prior SUDs, design-based multinomial logistic regression analysis revealed that young adulthood, higher educational attainment, higher personal income, never having been married, being divorced/separated/widowed, lack of lifetime substance use treatment, and stressful life events predicted significantly greater odds of past-year persistent/recurrent SUDs, relative to abstinence. In addition, remission from a prior tobacco use disorder decreased the probability of past-year persistent/recurrent SUD, relative to abstinence. Stressful life events were the only common correlates across the aggregation of all SUDs and each substance-specific SUD, but differences were found for specific stressful life events between drug classes. Nearly half (49%) of adults with prior DSM-5 SUDs continued to report past-year symptomatic substance use, while only one in seven individuals were abstinent. The findings suggest the value of examining remission associated with both substance-specific SUDs and aggregation of SUDs based on the shared and unique correlates of persistent/recurrent SUDs; this is especially true for stressful life events, which could be useful targets for enhancing clinical care and interventions.
