This dissertation investigated the levels of self esteem, general anxiety, and test anxiety, and their inter-relationships among white, black, and Spanish surnamed students in grades nine through twelve. The relationships of sex and grade levels to these variables were also examined. A group of 2,448 students from two public high schools were tested, using Coopersmith's Self-Esteem Inventory, and two other anxiety scales. Analysis of variance of self-esteem data showed statistically significant main effect differences for race, grade levels, and their interactions, but not for sex. Correlational analysis of the data showed a positive relationship between the two anxiety scales, and a negative relationship between each anxiety scale and self-esteem data. Analysis of some data did not show a clear pattern of the effects of sex, race, and grade levels. It was concluded that sex is not a major determinant of students' anxiety level, but that ethnicity is. (Author/AM)
