Randomized. Over an 18-month period, 213 people were screened for inclusion in the study. Of these, 127 with initial diastolic blood pressure of 90 to 109 mm Hg, systolic blood pressure of 189 mm Hg or less, and final baseline blood pressure of 179/104 or less mm Hg were randomized to treatment. Of the 127 participants, 16 did not complete follow-up blood pressure measurements. Thus, 111 subjects completed the study. All subjects were pretested over a four session baseline period on clinic blood pressure, ambulatory blood pressure, cardiovascular and emotional reactivity, and quality-of-life measures. Subjects were then randomly assigned, 36 to TM, 37 to PMR, and 38 to lifestyle modification education control and followed monthly with major post-tests at three months and eighteen months on these variables. The primary outcome variables were changes in clinic systolic and diastolic blood pressure values measured blindly. The secondary outcomes were changes in self-monitored home blood pressure and compliance.
