L. Dixon et al., ONE-YEAR FOLLOW-UP OF SECONDARY VERSUS PRIMARY MENTAL DISORDER IN PERSONS WISH COMORBID SUBSTANCE USE DISORDERS, The American journal of psychiatry, 154(11), 1997, pp. 1610-1612
Objective: Service utilization and outcomes of dually diagnosed patien
ts with independent mental disorders and those with substance-induced
mental disorders were compared. Method: Diagnosis, service use, and se
verity of substance use problems at baseline and 1 year later were ass
essed in consecutively admitted inpatients with independent mental dis
orders plus substance use disorders (N=81), substance-induced mental d
isorders plus substance use disorders (N=38), and independent mental d
isorders only (N=59). Results: At follow-up, patients with substance-i
nduced mental disorders at baseline were more likely to have been reho
spitalized than the other groups, were more likely to have used outpat
ient substance abuse services, were less likely to have an independent
mental disorder, and had the most severe alcohol- and drug-related im
pairment. Conclusions: Treatment programs for both types of dual diagn
osis patients must address mental health concerns.
