Untersuchung der faktoriellen Struktur des Kid-KINDL

Abstract

Zusammenfassung. In der vorliegenden Arbeit wurden die faktorielle Struktur und die Messinvarianz der Kid-KINDL Selbst- und Fremdeinschätzung bei 8- bis 11-jährigen psychisch kranken Kindern untersucht (Kid-KINDLSelbst: N = 441, Mädchen: 52 %, Jungen: 48 %, Alter: M = 9.44, SD = 1.12; Kid-KINDLFremd: N = 462, Mädchen: 55 %, Jungen: 45 %, Alter: M = 9.51, SD = 1.11). An einer ersten Stichprobe ergaben sich in Explorativen Faktorenanalysen Hinweise auf zwei zusätzliche Psychopathologie-Faktoren. Mit konfirmatorischen Faktorenanalysen wurden an einer zweiten Stichprobe unterschiedliche Modelle untersucht. Das Modell mit Doppelladungen krankheitsassoziierter Items auf den HRQoL-Faktoren und Psychopathologie-Faktoren zeigte die beste Modellanpassung, wobei die HRQoL-Dimensionen mit den Pathologie-Faktoren unkorreliert waren. Zwischen Selbst- und Fremdeinschätzung konnte partielle metrische Invarianz nachgewiesen werden. Die Eindimensionalität einiger Items muss aufgrund der Ergebnisse angezweifelt werden, was eine valide Erfassung einiger HRQoL-Dimensionen einschränken dürfte. Für den Einsatz in der Qualitätssicherung empfehlen sich die Kid-KINDL Skalen Selbstwert, Familie und Freunde.


Measuring Health-Related Quality of Life of Mentally Ill 8- to 11-Year-Old Children in the Context of Quality Assurance: An Investigation of the Factorial Structure of the Kid-KINDL

Abstract. Health-related quality of life is an important indicator for quality assurance of inpatient psychosomatic treatments. The present study examined the factorial structure and measurement invariance of self- and proxy-assessment on the Kid-KINDL in 8- to 11-year-olds with mental illness. The data were collected between 2015 and 2019 (Kid-KINDLSelf: N = 441, girls: 52 %, boys: 48 %, age: M = 9.44, SD = 1.12; Kid-KINDLProxy: N = 462, girls: 55 %, boys: 45 %, age: M = 9.51, SD = 1.11). In a first, randomly generated sample, exploratory factor analyses revealed evidence for two additional psychopathological factors. We tested different measurement models on a second sample with confirmatory factor analysis (MLR estimation). The model with item double-loadings on the HRQoL dimensions and the psychopathological factors that did not correlate with the HRQoL dimensions showed the best model fit (Kid-KINDLSelf: N = 294, RMSEA = .046, CFI = .92; Kid-KINDLProxy: N = 308, RMSEA = .050, CFI = .93). Partial metric invariance was demonstrated. Based on the results, the unidimensionality of some items must be doubted, which may limit a valid assessment of some HRQoL dimensions. The Kid-KINDL scales self-esteem, family, and friends are recommended for use in quality assurance.
