at baseline, the sample in this study were experi- encing headaches at least 6 days per month, the average headache chronicity was 19 years, and 70% had more than one type of headache. All participants were diagnosed as major depressive disorder, and 71% also had at least one anxiety disorder (four par- ticipants had four or five anxiety disorders each). Despite these statistics emphasizing the multiple and severe disorders that par- ticipants in the sample experienced, comparing the CBT and RPC groups showed significant improvements in the treatment group relative to the control group in terms of headaches, depression, anxiety, and quality of life; and these changes in the CBT group were maintained at four month follow-up.
