Self-pluralism: assessment and relations to adjustment, life changes, and age.

Individuals differ in the degree to which they see themselves as behaving and feeling similarly or differently in different situations and at different times. This dimension of the self-concept, which is conceived to extend from strong constancy of the self-concept at one extreme to marked variability at the opposite pole, is designated as self-pluralism. An inventory for the assessment of degree of self-pluralism--the Self-Pluralism Scale (SPS)--is presented, and the correlations of this scale with other relevant personality measures are reported. Several studies utilizing the SPS are presented. The results indicate that self-pluralism is negatively related to psychological adjustment, positively related to long-term real-life variability, and negatively related to age.
