This study was conducted to examine the structure of factors of STAXI-Japanese-version among the people with circulatory-diseases and normal healthy group, and to compare their scores among three groups with diseases (hypertension / coronary heart disease /both). (STAXI, which were developed by Spielberger et al. has two sub scales. One is State and Trait Anger Scale(STAS), the other is Anger Expression Scale (AX). STAS was desigend to assess the intensity of anger as an emotional state (state anger) and individual differences in anger proneness as a personality trait (trait anger). After examining the research on anger expression, AX scale was developed. This AX has 3 sub-scales for measuring suppressed anger (anger in), anger expressed toward other people or the environment (anger out), and the control of anger (anger control).)
As it was proven, STAXl-Japanese-version has an almost equal structure of factors to the American-version. In addition, it has ample reliability. But in two sub scales (anger in & anger control), there exists some validity problems which may come from cultural differences between Japan and U.S. A. And, the scores of 3 sub-scales(state anger, trait anger, anger out) were related to the patients under 60's who are suffering from both hypertension and CHD.
As the results, anger should be studied more in relation to circulatory diseases in consideration of cultural differences.
