Imagine you are attending a conference on psychotherapy. A therapist presents findings about a new form of therapy that has been developed and tested in a small sample of people. Patients' scores on a measure of social anxiety are lower following 20 weeks of the new therapy with 50 percent of patients described as "recovered" at the end of treatment. A member of the audience asks, "Has this treatment been proven to be better than the spontaneous remission rate for social anxiety?" Which of the following is another way to ask this same question? What percentage of people with social anxiety disorder recover over 20 weeks without any treatment? Are therapists being adequately trained in this new technique? How does this treatment compare to medication? Is the outcome measure valid?
