Cross-cultural assessment of childhood temperament

Abstract.

The Emotionality Activity Sociability (EAS) questionnaire focuses on heritable individual differences in reactivity and behavior which are often referred to in developmental temperament research. Psychometric properties of the French version of EAS were examined in a sample of 197 school-children aged six to 12 years. Parents, teachers and children aged nine years and more completed parallel forms of the EAS questionnaire. Confirmatory factor analysis was used to examine the fit between the original factors and the data. Internal consistency of each subscale, inter-rater and external validity were also examined. Children-rated EAS showed the best indices of fit between the four hypothesized factors and the data, but internal consistency was generally lower than in adult-rated questionnaires. Shyness and sociability showed significant overlap in both parent and teacher-rated EAS. The low concordance between child- and adult-ratings indicates that temperament evaluation and interpretation of items may be influenced by subjective and/or developmental factors. Results are discussed in the perspective of validity versus cross-cultural comparability of temperament measurement. The theoretical four-factor structure was not completely replicable in our sample.
