Cognitive imagery and physiological feedback relaxation protocols applied to clinically tense young adults: a...

Examined changes in targeted and general tension behaviors as well as reductions in physiological tension associated with cognitive imagery and electromyographic biofeedback relaxation procedures. Three groups of 15 female college students participated. During three weekly sessions each person received either guided cognitive imagery relaxation, frontalis muscle feedback relaxation, or a self-rest control procedure. The Anxiety Differential was administered before and after each session, while frontalis EMG, heart rate, and skin temperature were monitored continuously. A second Temperament Analysis was administered after the final session. The imagery procedure was associated with moderate reductions in physiological tension and significant reductions in state anxiety and three tension-related personality dimensions. Self-rest persons displayed lesser reductions in general tension with little physiological change. While biofeedback persons showed the largest reductions in physiological tension, they displayed only small and variable changes in state anxiety and personality dimensions. The data raise continued questions about the application of physiologically based operant relaxation procedures and support the use of cognitively mediated protocols for the treatment of specific or general anxiety behaviors.
