Description
Summary:The present investigation was designed to determine by factor analysis the nature of the items that comprise the A‐State and A‐Trait scales of the State‐Trait Anxiety Inventory. Three factors were identified. Factor I was defined exclusively by items from the A‐State scale. The underlying dimension tapped by the scale was interpreted as state anxiety (how one feels at a particular moment in time); support thus was provided for Spielberger's A‐State concept. Items from the A‐Trait scale, however, identified two separate factors, neither of which was clearly consonant with Spielberger's concept of A‐Trait. Factor II appeared to tap state anxiety according to how the individual generally feels or a typical level of state anxiety as remembered over an indefiniteperiod of time. Factor III was interpreted as a meamre of neuroticism.
