 note = {Recent reseach has suggested that styles of anger expression such as anger-in, anger-out, and anger-control contribute to the development of coronary heart disease (CHD).
In the 1980s, an increasing number of studies indicated that anger and hostility were directly related to CHD. Dembroski et al. (1985) reported a relationship between angiographically documented coronary arteriosclerosis and anger and hostility. Williams et al. (1980) found a relationship between the scale of hostility on the Minnesota Multiphasic Personality Inventory (MMPI), the degree of arteriosclerosis, and the mortality rate for CHD.
In addition, Spielberger (1988) developed the State-Trait Anger Expression Inventory (STAXI) to measure state anger, trait anger, and anger expression. The factor structure of anger on this scale was reasessed and modified in STAXI-2 in order to screen for hypertension and CHD in a medical setting.
The current study investigated the effects of anger expression on cardiovascular response to a stress situation. Twenty-four students were classified as a high anger control-out group (n=14) or a low anger control-out group (n=10) based on their scores on the anger control-out subscale of STAX-2. Both groups performed a cognitive reaction time task (23 trials) that participants had to start over if not done well. During task performance, the heart rate (HR), blood pressure (SBP,DBP), and spectral indices of HRV such as low frequency power (LF), high frequency power (HF), and the ratio of LF power to HF power (LF-HF ratio) were measured.
Results indicated that changes in the cardiovascular response decreased significantly in the low anger control-out group. However, the high aner control-out group had a high SBP and LF-HF ratio.
In the terms of their Profile of Mood States (POMS), tension-anxiety decreased significantly for the low anger control-out group while it increased significantly for the anger high contro-out group after the stressful task. These results suggest that an anger high control-out style is a spychological risk factor associated with the development of hypertension and CHD.

【目的】怒りや敵意、攻撃性は、冠動脈性心疾患（CHD)などの危険因子であり、とくに怒りの表出性や表出抑制が重要な要因である。本研究では、STAXI－2の下位尺度で、怒りの外的な表出を防ぐために自己を監視するAnger Control-Out （AC-O）に焦点を当て、ストレス事態における怒りの抑制傾向が心臓血管系反応に及ぼす効果について検討した。【方法】実験参加者：185名（男48名、女137名）に対し、STAXI-2を配布し、下位尺度であるAC-O得点の平均から±0.5SDを超えた高得点群14名（男5名、女9名；平均20±0.6歳）、低得点群10名（男4、女6名；平均20±1.1歳）を対象とした。生理学的反応の測定：HR、SBP、DBP、LF/HF比を測定した。手続き：ストレス事態は、図形認識課題を用い、23試行、10分間行った後、5分間の回復期を設定した。また、実験前・後の気分の変動を測定のため、POMSへの回答を求めた。【結果】SBPをLF/HF比において群の主効果と群と時間の交互作用が認められた。高群では、課題中の交感神経活動が高まり、さらにその状態が維持され、POMSの結果でも緊張や不安の上昇が認められた。【結語】AC-O傾向は、高血圧症やCHDの発症に関連する心理的な危険因子であることが示唆された。},
