Description: The purpose of this quasi-experimental design study was to test the effect of a progressive relaxation intervention on anger, personal strain, blood pressure, and heart rate in employed African-American women at risk for the development of essential hypertension. The subjects met the following inclusion criteria: (a) African-American female, (b) family history of hypertension, (c) a score at or above the 75th percentile on an anger suppression measure, and (d) self-report of personal strain. Subjects with treated or untreated hypertension were excluded from the study.

The 43 study subjects were employed as service workers at a state-operated facility in central Florida. The dependent variables for the study included (a) anger suppression, state anger, and trait anger as measured by the State-Trait Anger Expression Inventory; (b) vocational, psychological, interpersonal, and physical strain as measured by the Personal Strain Questionnaire; and (c) systolic and diastolic blood pressure, mean arterial pressure, and heart rate. The total subject participation time was eight weeks.

The experimental group (n = 22) was instructed in a progressive relaxation intervention. Audio cassette tapes prepared by the investigator were used by the subjects for home practice. The control group (n = 21) was asked to watch a self-selected television program or listen to a radio program for 30 minutes daily. The subjects in the experimental and control group were visited weekly by the investigator.

A multivariate repeated measures analysis of variance procedure was used for data analyses. Correlational analyses were also done to examine the relationships among the dependent variables. The level of significance was set at p $<$ 0.05. The experimental group had significantly lower mean interpersonal (p = 0.0001) and physical (p = 0.0001) strain scores than the control group at the conclusion of the intervention. The experimental and control groups both had significant reductions in state anger (p = 0.0012), trait anger (p = 0.0033), anger suppression (p = 0.0001), and psychological strain (p = 0.0001). There were no significant reductions in vocational strain, blood pressure, and heart rate in the experimental or control group.
