Confirmatory maximum likelihood estimation of measurement models was used to evaluate the construct generality of self-report measures of anxiety across male and female samples. These measures included Spielberger's State-Trait Anxiety Inventory, Taylor's Manifest Anxiety Scale, and two forms of Endler, Hunt and Rosenstein's S-R Inventory of Anxiousness. Data from 256 females and 135 males were analyzed by testing a sequence of hypotheses regarding equality of measurement properties of each scale across groups. The generality of the measurement model identified for each scale was assessed by examining the extent to which the obtained model was factorially invariant across sex groups. Results indicate that, with the exception of the Manifest Anxiety Scale, all measures obtained statistically invariant factor patterns across groups. Implications of these findings for the measures' practical use in multiple group comparisons are discussed. (Author/PN)
