Adolescent personality: a five-factor model construct validation.

The purpose of this study was to investigate convergent and discriminant validity of the five-factor model of adolescent personality in a school setting using three different raters (methods): self-ratings, peer ratings, and teacher ratings. The authors investigated validity through a multitrait-multimethod matrix and a confirmatory factor analysis correlated trait, uncorrelated method model. With the exception of Emotional Stability, each analysis demonstrated similar patterns and together provided support for the convergent and discriminant validity of the five-factor model structure of adolescent personality. However, among the three raters, self-ratings of personality provided a comparatively weaker method for assessing adolescent personality. The influences of agreement between self and other raters are discussed in relation to contrast, perceiver, and target effects; expert observer effects; the degree of acquaintanceship; and the effect of the social context.

Personality structure as derived from parental ratings of free descriptions of children: the inventory of child individual differences.

Based on over 50,000 parental descriptors of children gathered in eight different countries, we used a combination of focus group sorting of descriptors in each country and factor analyses of instruments developed in four of the countries (United States, China, Greece, and the Netherlands) to describe children ages 3 to 12 years to select items for an instrument that would work well across countries to access personality. Through many factor analyses of indigenous items in each country, a core set of 141 items was used in three of the countries, with over 3000 parents responding to our instruments in China, Greece, and the United States. Much cross-comparative research analysis has resulted in 15 robust midlevel scales that describe the structures of parental descriptors that are common to the three countries. The data on the English (U.S.) sample are presented in detail. Links to temperament and behavior problems are presented and discussed.
