To better understand interrelationships of social anxiety, introversion, and self-esteem, 109 college students completed the SPS, SIAS, EPQ-R-SS, and SERS. Moderator analyses indicated social anxiety and introversion were not moderated by self-esteem (p > .05). However, significant main effects indicated a strong negative relationship between social anxiety and selfesteem and a moderate positive relationship between social anxiety and introversion. Problems with multicollinearity are likely to have masked relationships among variables. Chi-square analyses with the SPS indicated significant differences between low and high self-esteem subjects in the low (;( = 6.79,p < .001) and high social anxiety groups (;( = 7.94,p < .001). With the SIAS, significant differences were found between low and high self-esteem subjects in the high (;( = 6.89,p < .001), but not the low (p > .05), social anxiety groups. Furthermore, results suggest that self-esteem may be a stronger predictor of social anxiety than introversion. Results imply that methods for prevention, assessment, diagnosis, and treatment planning for social anxiety may be improved by considering the impacts of self-esteem and introversion.
