Moderating Effects of Intraindividual Variance across the Trait Descriptive Universe.
Johnson, John A.
Several researchers have recently suggested, on limited data, that personality measures are more valid for individuals for whom inter-item variance is low. Questions remain concerning the robustness of the effect reported in these studies and whether general traitedness or traitedness within specific dimensions will moderate correlations other than self- and peer-ratings. A study was conducted to examine self-peer rating correlations, moderating effects on the correlation between adjective self-ratings and scores on scales from the California Psychological Inventory (CPI), and moderating effects on the correlation between adjective peer ratings and CPI scale scores. College students (N=81) provided self-reports and peer-ratings on seven scales built from adjectives sampling the trait-descriptive universe and scores on the same seven dimensions from the CPI. The results did not support the robustness of either general traitedness or traitedness for specific dimension in moderating the correspondence between self- and peer-ratings, self-ratings and inventory scores, or peer-ratings and inventory scores. Subjects scoring below the median of inter-item variance did not show greater correspondence among self-ratings, peer-ratings, and CPI scores, casting doubt on the pervasiveness of the moderating effect of intraindividual variance in item responding.
