The authors examined the psychosocial correlates of 1) having a histor
y of any type of psychiatric treatment and 2) being staff-identified a
s a suitable candidate for treatment from an outpatient dual-diagnosis
program. They reviewed 1,303 consecutive patients in a 16-month perio
d who applied for substance abuse and/or dual-diagnosis treatment at a
Veterans Administration hospital. The sample included 665 individuals
describing a history of prior psychiatric treatment, 126 of whom were
referred for outpatient dual-diagnosis treatment. Data were collected
at the time of treatment application and included demographics, emplo
yment and treatment histories, and recent substance use. Even the broa
dest definition of dual diagnosis (having a history of any type of psy
chiatric treatment) was associated with higher rates of homelessness,
disconnection from social support systems, unemployment and vocational
disability, and treatment chronicity; a narrower definition selected
for even greater impairment. Substance abuse programs should anticipat
e significant case management needs in addition to psychiatric support
when treatment programs are expanded to include services to patients
with comorbid psychiatric illness.
