This study evaluated the efficacy of cognitive therapy and biofeedback training in lowering Dlood pressures of normotensives under no-stress and stress conditions. A cognitive therapy group was compared to biofeedback and habituation control groups with 32 normotensives. Subjects were taught to use the electronic sphygmomanometer that served as the device to measure blood pressure during pretreatment and posttreatment phases of the study. These measurement phases each consisted of three 19 minute periods. Trie first period consisted of no-stress, and then a stress period followed. Return-to-no-stress was the final period. Subjects in the cognitive therapy and biofeedbacK groups received five sessions of self-control training of 66 minutes each between the pre- and posttreatment phases. The cold pressor was the analogue stressor used to induce bxood pressure elevations,

This study compares the relative efficacy of systolic and diastolic biofeedback in lowering the systolic and diastolic blood pressures of normotensives. The importance of testing these biofeedback procedures lies in assessment of their potential as blood pressure self-control techniques for the treatment of essential hypertension.
