Abstract
The objective of this study is to adapt and validate for use in the adult Spanish population the treatment known as social effectiveness therapy (Turner, Beidel, Cooley, Woody, and Messer, 1994). We present results that were obtained by comparing an experimental-treatment group consisting of 16 participants with a waiting list control group, all with generalized social phobia (APA, 2000). The evaluation was carried out before and
after the treatment in both groups as well as in two follow-ups with the experimental group. The results in the experimental group show the short and long-term efficacy of social effectiveness therapy for all measures that assess social anxiety and avoidance. In contrast, the members of the control group did not experience improvement in any of the variables evaluated.
