Abstract
This study examined the validity and the components of the new Shyness/Self-Consciousness (
Si
1), Social Avoidance (
Si
2), and Self/Other Alienation (
Si
3) subscales of the Social Introversion (
Si
) scale of the MMPI-2. Data provided by 410 college students were used to evaluate subscale performance against self-report measures of constructs that were believed to be differentially related to the 3 subscales. Results suggested that the
Si
subscales are valid. It also appears that individuals with elevated scores on
Si
1 may be more socially anxious, less social, and have lower self-esteem; that those who have elevated
Si
2 scores may be more shy and less social; and that those with elevated
Si
3 scores may possess lower self-esteem and have a more external locus of control.
