| Abstract: | Motivated by previous reports of relaxation successes with hemophiliacs, we sought to isolate the value of relaxation strategies. The effects of progressive and self-control relaxation on spontaneous bleeding and collateral symptoms were tested with seven hemophiliacs in a combined multiple-baseline partial-crossover design. Following 6 or 12 weeks of training in either or both relaxation methods, there was no strong evidence that the treatment affected bleeding or perceived pain in these subjects. These disappointing results were obtained despite within-session physiological evidence of relaxation induction and self- and spouse reports of faithful relaxation practice. The present results failed to replicate previous findings, cast doubt on the stress theory of spontaneous bleeding, and recommend further research to clarify the role of psychological interventions for hemophiliacs. |
