This study examined psychometric properties of the Tempe Sorting Task (TST), a new measure of executive function (EF) for children. To increase the meaningfulness of test score interpretations, an age-appropriate construct was employed to incorporate Denckla's description of EF. Multiple measures of EF, including the TST, were collected for…

Results of an administration of the Language Proficiency Measure indicated that the interrater reliability was adequate, internal-consistency reliability estimates were high, concurrent validity coefficients were adequate, and the classification validity was acceptable. (Author/LMO)

Regression analyses indicated that the Coopersmith Self-Esteem Inventory has convergent validity with regard to the Piers-Harris Children's Self-Concept Scale and the Coopersmith Behavioral Academic Assessment Scale, has discriminant validity with regard to the Children's Social Desirability Scale, is sensitive to differences in achievement level,…

Researchers sometimes need a statistical test of the hypothesis that two values of Cronbach's alpha reliability coefficient are equal. The situation may involve scores from two different measures administered to independent random samples or from the same measure administered to random samples from two different populations. Feldt derived a test…

To control for response bias in student ratings of college teachers, an index of rater error was used that was theoretically independent of actual performance. Partialing out the effects of this extraneous response bias enhanced validity, but partialing out overall effectiveness resulted in reduced convergent and discriminant validities.…

Lafferty's Life Styles Inventory was completed by 556 managers (Level I, Self-Description) and by 2,922 peers, subordinates, and supervisors (Level II, Description by Others). Factor analysis revealed the same three factors in both ratings. Coworkers generally agreed with each others' ratings, but correlations between self and coworker ratings…

Although arbitrary, whenever multiple judgmental standard-setting procedures are utilized by different groups concurrently, stability across raters can be achieved and decisions can be made in a relatively judicious manner. Greater stability across methods (Ebel, Nedelsky, Angoff) may be effected by slightly modifying the Ebel approach. (Author/PN)

Using both the Behaviorally Anchored Rating Scales (BARS) and the Purdue University Scales, 727 undergraduates rated 32 instructors. The BARS had less halo effect, more leniency error, and lower interrater reliability. Both formats were valid. The two tests did not differ in rate discrimination or susceptibility to rating bias.

Results from a performance assessment in which 68 high school students wrote essays support the use of latent variable modeling for estimating reliability, concurrent validity, and generalizability of a scoring rubric. The latent variable modeling approach overcomes the limitations of certain conventional statistical techniques in handling…
