Although self-concept has been linked with many behavioral variables, most studies do not deal with dependent variables which would provide an understanding of such clinically relevant behaviors as sociability, aggression, activity level, somatization, inhibition, and sleep disturbance. The relationship between self-esteem and clinically relevant behavior was examined for ten-year-old children (N=70), who were divided into high (N=34) and low (N=36) self-esteem groups and were administered measures of behavior and self-esteem. Subjects with low self-esteem were more physically and verbally aggressive, had more bodily complaints, had higher activity levels, and were more inhibited than a comparison group with high self-esteem. The two groups did not differ on the dimensions of sociability or sleep disturbance. The findings suggest that self-esteem can be used to identify individuals who could benefit from counseling services for behaviors symptomatic of emotional problems. (Author/NRB)
