TREATING TYPE-A BEHAVIORS AND MILD HYPERTENSION IN MIDDLE-AGED MEN

Unmedicated mildly hypertensive Type A men were randomly allocated to one of three conditions: stress management intervention training (N = 15), Type A management (N = 15), and delayed Type A management intervention. Significantly greater reductions in blood pressure at rest and during the Type A structured interview were found following the active interventions than during the minimal treatment control period of the delayed intervention. Type A management was more successful in changing a number of Type A behaviours, including anger, hostility and global Type A behaviour. Changes on measures of anger-in, -out, hostility, and SI ratings of Type A behaviour were associated with changes in systolic and diastolic blood pressure reactivity during interview.
