Illustration of Multilevel Explanatory IRT Model DIF Testing with the Creative Thinking Scale

Das Ziel der vorliegenden Studie war die systematische Erfassung der Kreativitätsleistung bei 5- bis 14-jährigen Jungen mit Asperger Syndrom im Vergleich mit einer gesunden Kontrollgruppe (je n=24). Untersucht wurden sowohl quantitative Kreativitätsaspekte (Ideenflüssigkeit, Ideenflexibilität) als auch qualitative Kreativitätsaspekte (Originalität) bei zwei Altersgruppen (jüngere Kinder: 5 – 9 Jahre, ältere Kinder/Jugendliche: 10 – 14 Jahre). Die Ergebnisse zeigen, dass bei Kindern/Jugendlichen mit Asperger Syndrom primär die quantitativen Aspekte der Kreativität beeinträchtigt sind (Ideenflüssigkeit und -flexibilität bei gleichbleibenden Items aus dem 5-Punkte Test), während die Kreativitätsleistung bei den abwechslungsreicheren Bildergänzungsaufgaben des Torrance Test of Creative Thinking, bei denen die Qualität/Originalität im Vordergrund steht, unbeeinträchtigt ist. In unserer Stichproben waren die Alterseffekte signifikant (jüngere Kinder zeigten schlechtere Leistungen), aber über die Gruppen vergleichbar (d. h. die Interaktionseffekte waren nicht signifikant). Im Sinne einer ressourcenorientierten Diagnostik, die für eine maßgeschneiderte Interventionsplanung unerlässlich ist, sollten also zusätzlich zu den quantitativen auch die qualitativen Aspekte kreativer und exekutiver Denkleistungen erfasst werden.

Abstract. To investigate the effect of response alternatives/scoring procedures on the measurement properties of the Center for Epidemiologic Studies Depression Scale (CES-D) which has the four response alternatives, a polytomous item response theory (IRT) model was applied to the responses of 2,061 workers and university students (1,640 males, 421 females). Test information functions derived from the polytomous IRT analyses on the CES-D data with various scoring procedures indicated that: (1) the CES-D with its standard (0-1-2-3) scoring procedure should be useful for screening to detect subjects with “at high-risk” of depression if the θ point showing the highest information corresponds to the cut-off point, because of its extremely higher information; (2) the CES-D with the 0-1-1-2 scoring procedure could cover wider range of depressive severity, suggesting that this scoring procedure might be useful in cases where more exhaustive discrimination in symptomatology is of interest; and (3) the revised version of CES-D with replacing original positive items into negatively revised items outperformed the original version. These findings have never been demonstrated by the classical test theory analyses, and thus the utility of this kind of psychometric testing should be warranted to further investigation for the standard measures of psychological assessment.

Abstract. Self-determination theory (SDT) suggests that the degree of autonomous behavior regulation is a characteristic of distinct motivation types which thus can be ordered on the so-called Autonomy-Control Continuum (ACC). The present study employs an item response theory (IRT) model under the ideal point response/unfolding paradigm in order to model the response process to SDT motivation items in theoretical accordance with the ACC. Using data from two independent student samples (measuring SDT motivation for the academic subjects of Mathematics and German as a native language), it was found that an unfolding model exhibited a relatively better fit compared to a dominance model. The item location parameters under the unfolding paradigm showed clusters of items representing the different regulation types on the ACC to be (almost perfectly) empirically separable, as suggested by SDT. Besides theoretical implications, perspectives for the application of ideal point response/unfolding models in the development of measures for non-cognitive constructs are addressed.
