Validation and normalization of the Italian and German version of the DTLA (Detection Test for Language Impairments)



Detection Test for Language impairments in Adults and the Aged (DTLA) is a screening tool that has recently been developed, validated, and standardized by a Quebec, Belgian, French, and Swiss research team (Macoir, Fossard et al., 2017). Thanks to this new language screening tool, the presence of a language disorder can be identified more rapidly and also more precisely in adults with neurodegenerative disorders. Moreover, the DTLA is now part of the assessment tool kit of the acute phase for stroke patients in the province of Quebec (Quebec Ministry of Health and Social Services, 2019). Until now, this quick language screening test only exists in French, and has not yet been translated, validated and standardized in other languages. To fill this gap, the current project aims to validate and standardize the DTLA in two of the official Swiss languages,that is German and Italian. The successful completion of the German and Italian validation and standardization of this language screening tool will provide a new tool for clinicians and speech therapists in Switzerland in order to (better) identify language disorders in older adults and as a consequence improve their clinical practice.
