1. A researcher was interested in the effectiveness of cognitive behavioral
therapy in reducing social anxiety in a group of clients who were diagnosed
with mild social phobia. The researcher tested social anxiety in her clients
both before and after the cognitive behavioral therapy treatment. The
research question was whether there was a difference in the severity of
social anxiety before and after the treatment with cognitive behavioral
therapy.
