The relationship between capacity for absorption and chronic headache patients' response to relaxation and biofeedback treatment.

A sample of 49 chronic headache patients (35 vascular and 14 tension) was separated according to capacity for absorption (as measured by Tellegen & Atkinson's 1974 scale) into groups high in absorption and groups low in absorption, with patients in the middle range being excluded. Absorption capacity was found to affect response to treatment in complex ways. Vascular headache patients high in absorption were significantly improved following relaxation training, but not after biofeedback training. Vascular headache patients low in absorption were significantly improved after biofeedback training. Tension headache patients low in absorption did not respond significantly to either form of treatment, while those high in absorption responded significantly to biofeedback training. Reasons for these differences in response to treatment were discussed.
