Objective: Comorbidity of substance
abuse disorders with schizophrenia is associated
with a greater risk for serious illness
complications and poorer outcome. Methodologically
sound studies investigating
treatment approaches for patients with
these disorders are rare, although recommendations
for integrated and comprehensive
treatment programs abound. This
study investigates the relative benefit of
adding an integrated psychological and
psychosocial treatment program to routine
psychiatric care for patients with schizophrenia
and substance use disorders.
