KERF–Ein Instrument zur umfassenden Ermittlung belastender Kindheitserfahrungen
Erstellung und psychometrische Beurteilung der deutschsprachigen MACE (Maltreatment and Abuse Chronology of Exposure) Scale
Abstract
Hintergrund: Belastende Kindheitserfahrungen steigern das Risiko für Psychopathologie und beeinflussen die Erkrankungsschwere und den Behandlungserfolg. Validierte Instrumente zur umfangreichen Erfassung von Kindheitsbelastungen sind für die klinisch-psychologische Arbeit unabdingbar jedoch nur bedingt vorhanden. Fragestellung: Diese Arbeit stellt die Konstruktion und psychometrische Prüfung der Skala „Belastende Kindheitserfahrungen” (KERF), einem Instrument zur umfangreichen Erfassung von Kindheitsbelastungen vor. Die KERF beruht auf einer modifizierten Version des US-amerikanischen „Adversive Childhood Experiences” Index. Methode: Basierend auf den Daten von 165 Probandinnen wurden mit Rasch-Modellen zehn Subskalen modelliert. Korrelationen mit dem CTQ (Childhood Trauma Questionnaire) und Psychopathologie wurden bestimmt. Ergebnisse: Unterstützt durch konzeptuelle Überlegungen konnten zehn Subskalen gebildet werden. Wir fanden zufriedenstellende Assoziationen mit dem CTQ und Psychopathologie. Schlussfolgerungen: KERF ermöglicht eine detaillierte valide Erfassung belastender Kindheitserfahrungen.
Background: Adverse childhood experiences increase the risk of psychopathology and influence severity of mental ill-health as well as treatment outcomes. Clinical psychological work requires validated instruments to comprehensively assess childhood adversities. Objective: This paper deals with the construction and psychometric evaluation of the German version of the modified “Adverse Childhood Experience” Index, called “Belastende Kindheitserfahrungen” (KERF). This instrument assesses childhood adversity in depth. Method: Based on interview data of 165 female subjects, ten subscales were modeled using Rasch-Models. Correlations with the CTQ (Childhood Trauma Questionnaire) and psychopathology were analyzed. Results: Subscales were modeled, with the support of conceptual approaches. Satisfying associations with the CTQ and psychopathology were found. Conclusions: KERF enables a valid and detailed assessment of childhood adversities.
