Higher-order factors of the Big Five.

Estimated factor correlations from 14 studies supporting the 5 factor, Big Five model of personality trait organization--5 studies based on children and adolescents, 9 on adults--were factor analyzed. Two higher-order factors were clearly evident in all studies. One was principally related to the Big Five trait dimensions Agreeableness, Conscientiousness, and Emotional Stability; the other, the dimensions Extraversion and Intellect. Two models, one for children and adolescents, the other for adults, were tested by confirmatory factor analysis with generally excellent results. Many personality theorists appear to have considered one or both of these 2 metatraits, provisionally labeled alpha and beta.

The structure of temperament and personality in Russian children.

Russian schoolchildren (N = 480) 8-10 years old were rated by their teachers on 60 scales drawn from 3 sources: the temperament literature, studies of child personality, and Russian educators. Analysis of 21 temperament scales produced 4 meaningful components: sociability, anger, impulsivity, and fear. Component scores formed from these scales were then analyzed in the context of the remaining scales, leading to a solution that demonstrated the usefulness of the Big Five for the organization of personality characteristics in the Russian language and culture. The high degree of relation between the temperament dimensions and 4 of the 5 personality dimensions supports the view of many developmentalists that temperament not only is a major component of personality but may be the foundation of personality.

Five robust trait dimensions: development, stability, and utility.

Interest has grown in recent years in a five-factor model for the organization of personality characteristics. A brief history of the development of this model is given. It is evident that the model is very general, across variations in raters and ratees and across languages. There is also evidence that the structure of personality inventories reflects this model. Although most of the studies that have demonstrated the model have utilized either self-report inventories or have relied on ratings, there is clear evidence that both ratings and inventories are importantly related to actual behavior. A longitudinal study of children's personality traits is reported. Evidence for the five-factor model is examined, including data for the stability over time of characteristics organized in terms of the model. One trait of particular focus in this study has been Factor 3, often interpreted as Conscientiousness but here referred to as Will to Achieve because of its high correlations with formal measures of educational achievement. Studies indicate that this dimension is responsible for much of the variance in achievement left unexplained by aptitude measures.
