Existing literature focus mainly on subpopulations (children with hearing aids, children with CI) and is usually not epidemiological. Often children with additional needs (intellectual disability, visual impairment, autism spectrum disorder, complex syndromes) are excluded from the studies. This subgroup of children makes up around 1/3 of the population of children with hearing impairment.\n\nWhat factors contribute to the unexplained variance in language development in children with hearing loss? (including children with additional needs, multilingual) There is a lack of European epidemiological studies that evaluate the effects of Newborn Hearing Screening and early intervention.', 'detailedDescription': 'Aims:\n\n* to collect population based data on children born in Upper Austria with a significant hearing impairment and to describe this population in detail regarding audiological, etiological (including geno- and phenotypical correlations), neurodevelopmentally, psychological, psychiatrically and linguistically with a special interest is in children with additional needs\n* collecting child development outcomes (language, communication, psychosocial) and family outcomes (quality of life, stress)\n* to investigate possible effects of the Newborn Hearing Screening, early intervention and specific parent behaviors targeted in early intervention\n* collecting developmental trajectories of the total sample and subgroups of the sample (particularly audiological, etiological and cognitive).
