Validierung des QbMini Tests zur Diagnose der Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) bei fünfjährigen Kindern

Abstract

Zusammenfassung. Fragestellung: ADHS tritt bei 2 %-8 % aller Vorschüler auf. Zur Diagnose von ADHS im Vorschulalter gibt es derzeit nur wenige Verfahren. Ziel dieser Studie war die Validierung des psychometrischen Verfahrens QbMini Test für das Vorschulalter. Dieser PC-gestützte Test erfasst Aufmerksamkeit und Impulsivität anhand eines Daueraufmerksamkeitstests, während die Hyperaktivitätsmessung über eine Infrarotkamera erfolgt. Methodik: Der QbMini Test wurde mit 95 5-jährigen Kindern mit und ohne ADHS durchgeführt. Die Eltern füllten symptomspezifische Verhaltensbögen für ADHS aus. Ergebnisse: Der QbMini Test erfasst die drei Hauptsymptome von ADHS. Aus dem Vergleich des QbMini Tests mit den Verhaltensbogen ergaben sich insbesondere für den Faktor Hyperaktivität signifikante Korrelationen. Schlussfolgerungen: Die ersten Daten sprechen dafür, dass der QbMini Test in der ADHS-Diagnostik im Vorschulalter eine gute Ergänzung zu den bestehenden Verfahren ist.

Is the QbMini a Valid Instrument for ADHD Assessment?

“…The factor analysis revealed that the different variables computed when children perform the QbMini task while filmed by an infrared camera mapped onto the three symptom domains. This three-factor model is in line with analyses performed on the already validated QbTests (Reh et al, 2015;Ulberstad, 2012aUlberstad, , 2012b as well as the QbMini itself (Zaplana Labarga et al, 2019). An earlier factor model of the QbMini (Lamm, 2013) consists of only two factors (inattention and hyperactivity/impulsivity), in line with others performed on the QbTest and the conception of the FBB-ADHS-V, in which hyperactivity and impulsivity are merged into one scale as well.…”

“…First, the test must be able to differentiate between the three main symptoms of ADHD (construct validity). Comparing to the previous results of Zaplana Labarga et al (2019), we expected that the variables of the QbMini can be classified into three factors for hyperactivity, inattention, and impulsivity. In the second step, we wanted to examine the diagnostic ability of the QbMini.…”

“…The purpose of this study is to extend earlier research investigating its ability to assess ADHD symptoms. A factor analysis performed on the QbMini variables revealed a three-factorial model consisting of the following factors: inattention, hyperactivity, and impulsivity (Zaplana Labarga et al, 2019). In addition, the authors have shown that the QbMini can reliably differentiate between 5-year-old children with ADHD and healthy controls.…”

“…In the second step, we wanted to examine the diagnostic ability of the QbMini. As the QbMini had been able to differentiate between healthy children and children with ADHD (Zaplana Labarga et al, 2019), the focus of this study was to examine whether the QbMini could also differentiate between children with ADHD and children with another developmental disorder (specific language impairment, SLI). The QbMini and clinical questionnaires use different methods to detect symptoms of ADHD.…”

The Structure and Diagnostic Accuracy of the QbTest in Pediatric ADHD: A Retrospective Clinical Study

“…After this initial validation, very few studies have replicated these findings to further explore the structure of the QbTest in pediatric populations (Table 1). Reh et al (2015) also found three factors in explorative factor analysis (EFA), and so did Labarga et al (2019) in a principal component analysis (PCA) study, while Hirsch and Christiansen (2017) and Hamadache et al (2021) reported only two factors. However, Hirsch and Christiansen (2017) found three factors in separate confirmatory factor analysis (CFA).…”
