This study compared four methods for setting item response time thresholds to differentiate rapid-guessing behavior from solution behavior. Thresholds were either (a) common for all test items, (b) based on item surface features such as the amount of reading required, (c) based on visually inspecting response time frequency distributions, or (d)…

The Computer Anxiety Scale was tested for invariance over the grouping conditions of males/females and graduate/undergraduate status. Subjects included 187 undergraduates and 188 graduates; analyses were conducted on 136 males and 236 females. Results indicate that the construct of computer anxiety appears to be multidimensional with highly…

Several methods for estimating item response theory scores for multiple subtests were compared. These methods included two multidimensional item response theory models: a bi-factor model where each subtest was a composite score based on the primary trait measured by the set of tests and a secondary trait measured by the individual subtest, and a…
