Behavior modification in the treatment of hypertension

This study examines the use of a behavior modification program as an adjunct to the medical treatment of essential hypertension. The subjects, outpatients with medically treated, but uncontrolled, essential hypertension, were exposed to group interaction (including such processes as peer reinforcement, peer competition, and cognitive dissonance), individual blood pressure monitoring, stimulus control, and direct social influence. The control subjects received only routine medical treatment for their hypertension. Results indicated that the experimental subjects significantly decreased their diastolic blood pressures between pre- and post-treatment measures (spanning a period of four weeks), whereas the control subjects showed no such change. Thus it appears possible to use behavior modification to help in the treatment of essential hypertension.
