Аннотация
OBJECTIVES: With reference to an epidemiological sample of adolescents and young adults the impact of different models on the number of children classified as having specific reading and spelling problems is investigated.
METHODS: Using the same set of data, the effects of alternative measurement models, definitions and methodological procedures on the prevalence of specific spelling problems are shown. The virtual consequences of various norm-oriented definitions of cases are discussed with reference to external empirical criteria.
RESULTS: In the present study case definitions of specific spelling retardation based on substantial criteria result in prevalence rates between six and nine percent.
