Abstract (eng)
Diagnostic interviews with parents as a part of multimethod diagnostic are routinely conducted in a developmental diagnostic assessment with preschool children. The aim of this study was to examine which differential meaning of parental information in the assessment process, and furthermore, which additional value they contribute compared to another diagnostic methods. For this purpose parental interview guidelines, test results of the Wiener Entwicklungstest (WET, Kastner-Koller & Deimann, 2012), observations of behavior of children aged 3.0 - 6.0 years (N = 269) were provided by the Test and Counseling Centre of the Faculty of Psychology (University of Vienna). The diagnostic contribution and additional value of parental information were investigated on a random sample (N = 88) for the three diagnosis groups, advanced development (n = 30), developmental delays (n = 28) and problems in attitude to work (n = 30). Data was analyzed qualitatively and quantitatively by a mixed-method design according to the questions. A stepwise discriminant analysis showed that parental information about understandability of speech followed by media consumption, birth weight and extraversion were the best indicator for prediction of the diagnosis group affiliation. They obtained together a quality classification of 66.3 %, whereby extraversion played an important role for children with problems in attitude to work. When further parental information (fine motor skills, first footsteps, beginning to speak, self-independence, preschool skills, disagreeableness) were simultaneously included, the hit rate increased to 73.2% and had beneficial effects on the quality prediction of children with developmental deviation. With the exception of understandability of speech, which can be also assessed by observation of behavior, an additional benefit was contributed by media consumption, birth weight and extraversion, as well as the reason for initial approach and parental descriptions of symptoms of children showing advanced development and development problems.
