title: A Two-Factor Model of Temperament.
abstract: The higher order structure of temperament was examined in two studies using the Adult Temperament Questionnaire. Because previous research showed robust levels of convergence between Rothbart's constructs of temperament and the Big Five factors, we hypothesized a higher order two-factor model of temperament based on Digman's higher order two-factor model of personality traits derived from factor analysis of the Big Five factors. Study 1 included 258 undergraduates. Digman's model did not fit the data well, so we conducted an exploratory two-factor solution. One factor included extraversion/positive emotionality, orienting sensitivity, and affiliativeness, and the other, negative affect versus effortful control content. This two-factor model of temperament model diverged from the Digman model only on the agreeableness-affiliativeness loadings. Study 2 involved a community sample of 700 participants. Confirmatory factor analysis supported the alternative model found in Study 1. Findings are discussed in relation to research on attention and emotion.
