CRITICAL PROCEDURAL VARIABLES RELATED TO THE PHYSIOLOGICAL-EFFECTS OF PROGRESSIVE RELAXATION - REVIEW

Twenty-five investigations of the physiological effects of progressive relaxation training were classified according to whether relaxation was found to be superior or equivalent to control conditions. The two sets of studies differed significantly on number of training sessions and in the use of taped vs live administration of training, and they tended to differ in the use of normal vs patient samples. The likelihood of producing significant physiological reductions via progressive relaxation appears to be greater when multi-session, subject-controlled training is conducted with subjects for whom physiological activity contributes to a presenting. clinical problem. © 1979.
