Psychological changes accompanying and mediating stress-management training for essential hypertension

In a previous controlled study, 21 participants with essential hypertension were treated with a program based on education, relaxation and D'Zurilla problem-solving training, and another 21 participants were assigned to a waiting list control condition (García-Vera, Labrador, & Sanz, 1997). In this report, the pre-post-treatment psychological changes accompanying those conditions were examined with the Jenkins Activity Survey, the Rosenbaum Self-Control Schedule, the Spielberger State-Trait Anxiety Inventory, and the D'Zurilla-Nezu Social Problem-Solving Inventory. Treatment yielded significant psychological changes that included an increase of problem-solving abilities. Moreover, correlation and multiple regression analyses revealed that, when clinic blood pressure (BP) values were considered, increases in problem-solving abilities were correlated with systolic and diastolic BP reductions for participants in the stress-management condition, and they mediated partially the antihypertensive effects of stress-management training on BP. No significant correlations were found between psychological changes and self-measured systolic or diastolic BP reductions.
