AbstractThe purpose of the present study was to investigate the active cognitive ingredients of change in psychological treatments for long-term chronic headache complaints. The primary questions this study addressed were: (1) Is a cognitive self-hypnosis training which explicitly attempts to change appraisal and cognitive coping processes more effective in producing these changes than a relaxation procedure, and (2) are changes in pain appraisal and cognitive coping related to changes in pain and adjustment in the short and long term? A total of 144 patients were assigned at random to a cognitive self-hypnosis (CSH) treatment or autogenic training (AT) with a duration of 7 weeks. Measures used were: Headache Index (HI), Symptom Checklist-90 (SCL-90), Coping Strategy Questionnaire (CSQ), Multidimensional Locus of Pain Control Questionnaire (MLPC) and treatment expectations. The results indicated that patients successfully changed their use of coping strategies and pain appraisals. Cognitive therapy was more effective than relaxation training in changing the use of cognitive coping strategies which were the direct targets of treatment. However, treatment effects were only related with changes in the use of coping strategies and appraisal processes to a limited extent and the mediational role of cognitive processes in pain reduction and better adjustment was inconclusive.
