This study was designed to examine the relation of trait anger and anger expression to blood pressure, cholesterol, and depression in middle-aged Korean women.

This descriptive correlational design was conducted using a convenient sample taken from the health center of K University Hospital located in Kyungki province, Korea. The subjects were 252 women aged 40 to 64 years. Spielberger's state trait anger expression inventory - Korean version and Beck's depression inventory were used for measuring trait anger, state anger, anger expression and depression. Data was analyzed by descriptive statistics, t-test, Pearson correlation, two-way ANOVA, and cluster analysis using a pc-SAS program.

The anger expression types by cluster analysis were Anger out/in type, Low anger expression type, and Anger control type. The level of cholesterol and depression were significantly higher in women with high anger in and high trait anger. In addition, the level of depression was significantly higher in women with a high anger temperament.

Trait anger and anger in might be related to cholesterol and depression in women. However, this study does not reveal the relation between blood pressure and trait anger and anger expression.

This cross-sectional study was designed to identify anger-expression types in late school-age children and investigate the relation between the identified anger-expression types and their health status.

One thousand twenty seven children in elementary school fifth and sixth grades were recruited from November to December, 2004. Data was analyzed using descriptive statistics, cluster analysis, 2-test, ANOVA, Duncan's multiple comparison test, and Wilcoxon rank sum test.

Three anger-expression types in late school-age children were found; Anger-out/in, Anger-control, and Low anger-expression types. Children frequently using the anger-out/in type among the three types and with a higher state anger reported higher psychosomatic symptoms and depression. Children from a divorced or separated family reported higher state anger.

This study suggests that a specific anger management program needs to be developed for late school-age children with high state anger and frequently using the anger out/in expression type. For understanding the anger level and the anger expression types of Korean school-age children, further research needs to be done with large samples using a randomized sampling method.

This cross-sectional study was designed to identify anger-expression typesof adolescent women and investigate the relation between the identified anger-expression types and their problem behaviors and health status.

One hundred ninety nine high school freshmen were recruited from September to November, 2003. Data wasanalyzed using descriptive statistics, cluster analysis, χ²-test, ANOVA, and Duncan's multiple comparison test.

Three anger-expression types in adolescent women were found; Anger-out/in, Anger-control/in, and Anger-control type. Adolescent women with frequently using the anger-out/in type and with higher state anger reported more delinquent behaviors, more health risk behaviors, and higher psychosomatic symptoms. However, adolescent women with lower state anger and frequently using the anger-control type reported more depression scores.

There is a need to further clarify the relationship between anger-expression typesand depression in adolescent women. The findings suggest the necessity of a development of the program for lowering the anger level and controlling the unfavorable anger expression types such as the anger-out in.

The purpose of this study was to examine anger-expression patterns and their association with state and trait anger and physical and psychological health status in health care workers.

Four hundred and forty eight nurses, physicians and technicians from a large medical center completed standardized questionnaires of anger, anger-expression patterns and mood. They also had blood pressure, cholesterol, blood glucose and body mass index measured during their annual physical examinations. Data was analyzed using descriptive statistics, independent t-test, chi-square and ANOVA.

Subjects showed two major clusters of anger-expression patterns: anger-control and anger-in/out. Subjects with the anger-in/out pattern reported higher state and trait anger and more anxiety, depression and fatigue than subjects with the anger-control pattern. Physical health indicators, however, were not significantly different between the two clusters of anger-expression patterns.

Anger-expression patterns are associated with psychological health status but not with physical health status. Anger-expression patterns, however, need to be examined over time to assess their long-term effects on the physical and psychological health status in future studies.
