title: Multidimensionality of state and trait anxiety: factor structure of the Endler Multidimensional Anxiety Scales.
abstract: The Endler Multidimensional Anxiety Scales (EMAS) are derived from an interactional model of personality that proposes that anxiety is a function of the interaction of person and situation variables. The EMAS distinguish between state and trait anxiety and assume that both are multidimensional constructs. The EMAS were administered to 2,009 students in a neutral situation. Three factor analyses were performed to clarify the empirical relation between state and trait anxiety and the variables within the 2 domains. Results support the distinction between state and trait anxiety. Factor analysis of the state items provided support for the separate dimensions of cognitive and autonomic state anxiety. Factor analysis of the trait items provided support for trait anxiety multidimensionality. Four congruent factors were associated with increases in state anxiety in 4 general situations: Social Evaluation, Physical Danger, Ambiguous, and Daily Routines.
