In this study (1) exposure in vivo plus response prevention, (2) cognitive therapy and (3) a waiting-list control condition were compared on their efficacy on the treatment of hypochondriasis. Seventy-eight patients with a DSM-IV diagnosis of hypochondriasis were randomly assigned to one of these conditions. Patients in both active treatment conditions improved significantly on all the measures, whereas the patients in the waiting-list control condition did not improve. The improvements were clinically significant. Exposure in vivo plus response prevention and cognitive therapy were equally effective. The improvements were maintained at the 7 months follow up.
