OBJECTIVES: The co-occurrence of severe @entity1032 and @entity734 , or dual diagnosis, is prevalent and is associated with significant clinical and social problems. Most studies have treated @entity1 with a dual diagnosis as a homogeneous population, grouping together different substances of misuse. This study investigated whether subgroups defined by their main substances of misuse were heterogeneous. The primary hypothesis was that users of stimulants, such as @entity2072 or @entity889 , would be characterized by especially high rates of inpatient admission, violence, and self-harm. METHODS: Case managers' ratings were used to identify individuals with serious @entity1032 and comorbid substance abuse or @entity734 who were being treated by 13 community mental health teams in South London. Standardized instruments were used to elicit sociodemographic, clinical, social, and service use data. RESULTS: A total of 233 cases of comorbid @entity734 and @entity716 were identified. On the basis of best available information, 78 (34 percent) @entity1 were classified as @entity167 misusers only, 52 (22 percent) as @entity167 and @entity835 users, 29 (12 percent) as users of @entity835 only, and 55 (24 percent) as stimulant users; 19 @entity1 (8 percent) were excluded from the analysis. No significant differences were found between subgroups in the use of inpatient services and lifetime history of self-harm, but there was a significant difference in lifetime history of violence, which was more frequent among stimulant users. The @entity167 users were older and more likely to be white, but otherwise few differences between subgroups were suggested by exploratory analyses. CONCLUSIONS: Apart from differences in history of violence, little heterogeneity was found among subgroups of @entity1 with different types of substance misuse.
