title: The longitudinal psychometric properties of the EAS temperament survey in adolescence.
abstract: Studies on the psychometric properties of the EAS Temperament Survey (EAS) have produced equivocal results. In particular the psychometrics of the EAS are largely unknown in adolescence. Confirmatory factor analysis was used to explore the EAS structure in adolescents. Structural equation modeling was also used to assess measurement invariance and factor stability. A modified 4-factor model provided the best fit to the data and demonstrated reasonable longitudinal invariance and stability. Furthermore, the standardized factor scores correlated at near unity with the sum of observed scores, suggesting factor interpretations remained unchanged. However, the modifications suggest that further work is necessary.
