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