Peer reviewedMarsh, Herbert W.; Plucker, Jonathan A.; Stocking, Vicki B. – Educational and Psychological Measurement, 2001
Reanalyzed data from the Self-Description Questionnaire II (SDQII) from an earlier study of 376 gifted students, and a new study of 837 gifted students to explore alternative approaches to missing data and data normalization. Results strongly support the construct validity of responses to the SDQII by gifted adolescents. (SLD)
