Social phobia: individual response patterns and the long-term effects of behavioral and cognitive interventions. A follow-up study.

In this study the long-term effectiveness of Social Skills Training (SST) and Rational Emotive Therapy (RET), on social phobia was studied, as well as the differential influence of patient characteristics on treatment effectiveness. Fifty-seven patients were assessed 14 months after the post-test. Results showed that long-term effectiveness was independent of the response-pattern of the patients. Comparisons between methods, irrespective of the response-pattern of the patients, showed no differences in effectiveness in favor of either SST or RET. Explorative analysis indicated the potential predictive power for treatment-outcome of confederate ratings of overt behavior on the SSIT. Patients who needed additional treatment appeared to perform significantly worse on this measure at the pretest. No factors could be traced that predict relapse after a relatively successful treatment.
