The Relationship Of Mmpi-A Item Effectiveness To Item Content, Diagnostic Category, And Classification Accuracy, Kathleen D. Lynch
The Relationship Of Mmpi-A Item Effectiveness To Item Content, Diagnostic Category, And Classification Accuracy, Kathleen D. Lynch
Psychology Theses & Dissertations
Archer, Handel, and Lynch (2001) recently compared the item endorsement frequencies for the MMPI-A normative sample against two adolescent clinical samples. Results showed that the MMPI-A contains a substantial number of items that do not show a significant difference in item endorsement frequency between normative and clinical samples. The current study extends Archer et al.'s (2001) research in three ways: (1) it examines the item endorsement frequencies of the Supplementary scales, Harris Lingoes subscales, and subtle-obvious items; (2) it examines the Basic, Content, and Supplementary scales, and Harris Lingoes subscales with two homogeneous diagnostic criterion groups (as suggested by Archer, …
Examining The Equivalence Of Rater Groups In 360-Degree Feedback For Use In Leadership Development, Amy Fitzgibbons
Examining The Equivalence Of Rater Groups In 360-Degree Feedback For Use In Leadership Development, Amy Fitzgibbons
Psychology Theses & Dissertations
This study assessed the seldom-considered aspect of measurement equivalence across the three most common rater groups in 360-degree feedback systems. The graded response model for polytomous items was used to assess differential functioning of items and tests and applied to an archival data set of 664 ratees to determine the equivalence of peer, subordinate, and supervisor ratings of four leadership competencies. The results indicate that the leadership competencies were invariant across the three rater groups. The results and conclusions produced are discussed with practical implications in mind.
