Abstract
Zusammenfassung:Fragestellung: Die deutschsprachige Version des Strenghts and Difficulties Questionnaire-Self-Report (SDQ-S) hinsichtlich ihrer Reliabilität und Dimensionalität für Österreich zu überprüfen. Methodik: Dieser Fragebogen wurde 2529 gesunden Kindern und Jugendlichen im Alter von 11-18 Jahren (im Mittel 12.71 ± 1.4) vorgelegt. Berechnet wurden 4 Problem-Skalenwerte, 1 Gesamtproblemskalenwert sowie 1 Skalenwert prosoziales Verhalten. Deskriptive Statistik, Cronbachs Alpha sowie eine Varimax rotierte Faktorenanalyse nach der Hauptkomponentenmethode wurden berechnet. Ergebnisse: Cronbachs Alpha ist für die Gesamtproblemskala, die Skala emotionale Probleme und die prosoziale Skala > 0.63. Die anderen Skalen liegen unter 0.4. Es ergaben sich 5 Faktoren, die eine Varianz von 41.8% erklären. Die Item-Subskalen-Korrelationen sind ausreichend, die Faktorenstruktur entspricht für 3 Subskalen (Peerprobleme, Hyperaktivität, Verhaltensauffälligkeit) nicht der originalen Faktorenzusammensetzung. Schlussfolgerung: Die Reliabilität der Gesamt- und der erwähnten Subskalen wäre für ein Screeningverfahren gerade noch ausreichend, für die restlichen Subskalen ist dies nicht der Fall. Die Faktorenstruktur war nicht komplett replizierbar. Zusammenfassung: Die SDQ-Selbst-Version in ihrer deutschsprachigen Version wird für die Individualdiagnostik zur Zeit bei gleichzeitiger Verwendung von mehreren Informationsquellen empfohlen.
Summary:Objective: To assess the validity and the reliability of the self-report version of the Strength and Difficulties Questionnaire in an Austrian sample. Methods: The questionnaire was given to 2529 healthy children and adolescents aged 11-18 years (mean age 12.71 ± 1.4). Evaluation was performed according to given criteria, yielding a Total Problem Score, scores on four clinical subscales, and on one scale for pro-social behaviour. Descriptive statistics, Cronbach’s alpha, and a varimax rotated factorial analysis were calculated. Results: Cronbach’s Alpha was > 0.63 for the Total Problem Scale, the Pro-Social Behaviour Scale and Emotional Problems Subscale. Factorial analysis revealed five independent factors explaining 41.8% of the variance. The analysis revealed good item-subscale correlations, but could not replicate the original factorial structure completely. Normative data for the SDQ-Self for Austria are provided. Conclusion: The German self-report version of the SDQ should, at the moment, only be used with extended analysis of multi-informant information.
