Spinath, F. M. (2000). Temperamentsmerkmale bei Kindern: Psychometrische Güte und verhaltensgenetische Befunde zum deutschen Emotionalitäts-Aktivitäts-Soziabilitäts-Temperamentinventar (EAS) nach Buss & Plomin (1984). Zeitschrift für Differentielle und Diagnostische Psychologie, 21, 65-75.


The present study investigates the psychometric properties and the factorial structure of the German adaptation of the EAS Temperament Inventory (Buss & Plomin, 1984) in its parental rating form. The 20-item questionnaire measures Emotionality, Activity, Sociability, and Shyness. A sample of 708 twin children aged 2 to 14 years was rated by both parents on the German EAS (Angleitner, Harrow, Hempel & Spinath, 1991). The EAS proved to be a reliable instrument for the assessment of temperament even within a large age range, yielding satisfying internal consistencies and good interrater agreement. One exception, however, had to be made with regard to Sociability. Factor-analytic analyses showed that the conceptual distinction between Sociability and Shyness has not been sufficiently taken into account in the EAS. Additional validation of the EAS temperaments is provided by analyses of MZ and DZ twin similarities.
