Intersibling agreement for Goldberg's big five adjective markers.
In a sample of 240 college students intersibling agreement was examined for Goldberg's 100 unipolar Big Five adjective markers. Participants showed self-enhancement by rating themselves more favorably on three of the five traits (Agreeableness, Conscientiousness, and Culture/Intellect); however, self-ratings on Neuroticism were higher than siblings' ratings. Correlations among raters were moderate (mean r = .41) and comparable to values obtained in studies using peer ratings. The type of the sibling relationship, based on ratings of relationship quality, moderated the rank-order measures but not the mean agreement.
