Few studies of psychological interventions for essential hypertension have incorporated comprehensive coping skills treatment programs, evaluated the efficacy of such programs against credible, minimally effective controls, examined the effects of these interventions on pressor responses, or clarified the nature of person by treatment interactions. The present study examined the relative effectiveness of multimodal stress management training and a minimally effective treatment control (ie, GSR biofeedback training) in the treatment of essential hypertensives' blood pressure at rest and in response to simulated stressful interpersonal situations. At the conclusion of an 8 week training period, stress management participants exhibited reliably lower resting diastolic blood pressure and tended to exhibit lower systolic pressure than controls. The former condition maintained their lower pressures through a 6-month follow-up period, but decreases in controls over follow-up rendered the conditions equivalent in blood pressure. No differences between conditions emerged in analyses on pressor responses. Stress management training was somewhat more effective for individuals scoring low rather than high on measures of trait anxiety and irritability.
