ABSTRACT

Objective: In Sweden, the Addiction Severity Index (ASI) is the Swedish National Board of Health and Welfare's recommended substance use disorder assessment tool and used routinely for patient intakes. Our study of 213 individuals assessed for substance use disorder with the ASI used nine years of the National Patient Register and examined whether clinical social workers' assessments of addiction severity at baseline were associated with later hospitalizations for mental health disorder (MHD). Methods: ASI composite scores and interviewer severity rating were used to measure clients' problems in seven areas (mental health, family and social relationships, employment, alcohol, drug use, health, and legal) at baseline. A stepwise regression method was used to assess the relative importance of ASI composite scores, MHD hospitalization two years prior to baseline, age, and gender for MHD hospitalization seven years post-baseline. Results: Almost two-thirds of the individuals (63%) were hospitalized at least once for MHD in the seven years post-baseline. At the multivariable level, MHD hospitalization prior to baseline was the strongest predictor of future MHD hospitalization, followed by ASI composite scores for drug use, employment, mental health and, last, male gender. Conclusions: A key finding is that higher ASI composite scores for drug use and mental health are predictors of future need for MHD treatment. Future studies will replicate this effort with a national population of individuals with substance use disorder.
