Social phobia in an outpatient alcohol and drug treatment sample.
OBJECTIVE
To examine characteristics of patients with social phobia (SP) in alcohol and drug treatment settings and to identify features distinguishing this group from patients with and without other psychiatric conditions.


METHODS
A random sample of 105 patients completing an initial assessment at two outpatient alcohol and drug treatment services were assessed and agreed to a 9 month follow-up interview, completed by n=102 (97%). At baseline the Composite International Diagnostic Interview (CIDI) was administered. Current diagnoses at baseline were used to separate the sample into those with SP (n=33), other current psychiatric disorders (OPD, n=40), and those with no current psychiatric diagnosis other than a substance use disorder (NPD, n=29). The novel methodology used in this study compared the SP group first to the NPD group to see if SP was associated with a different presentation, and then compared the SP group to the OPD group to see if any identified differences were associated with SP per se or psychopathology generally. The three groups were compared on demographic, current clinical, and past treatment utilization variables at baseline, while follow-up data were used to compare the groups on treatment outcome and treatment utilization.


RESULTS
The SP group did not differ from either group in a systematic way. What differences did emerge tended to show a difference between OPD and NPD, with SP intermediate between the two, or that SP and OPD together were different from NPD.


CONCLUSIONS
Despite the relatively small sample size, these findings suggest that in substance use disorder treatment settings, patients with coexisting SP do not represent a distinctly high-needs or at-risk group in the broader context of patient populations, for which coexisting psychiatric diagnoses are the norm rather than the exception.
