Background:
Studies examining the effects of substance use in patients with schizophrenia have produced conflicting results.
Aims:
To examine the effects of comorbid substance use on symptoms, social functioning and service use in patients with schizophrenia.
Method:
Patients (n=316) with and without substance use problems from three centres participating in the Scottish Comorbidity Study were compared, using research interviews and case note review, on measures of symptoms, social functioning and service use.
Results:
Patients with substance use problems were younger, more likely to be male and had shorter duration of illness. They had more police contact and increased self-reported needs, but otherwise showed few differences when compared with those without such problems.
Conclusions:
The presence of problem substance use had only modest impact on service use, symptoms or social functioning for this group of patients with schizophrenia. This has important implications for service development to meet the perceived needs of this group.
