Abstract

The identification of speech sounds disorders is an important everyday task for speech and language therapists (SLTs) working with children. Therefore, assessment tools are needed that are able to correctly identify and diagnose a child with a suspected speech disorder and furthermore, that provide a baseline for clinical decision-making concerning the choice of the most appropriate intervention approach. Assessment instruments need to fulfil a number of psychometric criteria regarding: a) test constructions, b) reliability and validity as well as c) the option of a correct diagnosis. A review of the existing speech assessments in Denmark showed that none of the materials fulfilled current recommendations identified in research literature. Therefore, the aim of this paper is to describe the evaluation of a newly constructed instrument for assessing the speech development and disorders of Danish-speaking children aged 2;6-6;11 years. The psychometric criteria of reliability and validity were investigated for the new assessment tool LogoFoVa (Clausen, 2014). These investigations were carried out on two Danish-speaking populations: 344 typical developing children (Clausen, in prep) and 112 children with suspected speech disorder (Clausen and Fox-Boyer, in prep). The results indicated that the instrument showed strong inter-examiner reliability for both populations as well as a high content and diagnostic validity. Hence, the study showed that the LogoFoVa can be regarded as a reliable and valid tool for the assessment of Danish-speaking children’s speech development and for differential diagnosis of children with suspected speech sound disorders.
