Purpose: To cross-culturally adapt and validate the Radboud Dysarthria Assessment (RDA) and the speech component of the Radboud Oral Motor inventory for Parkinson's disease (ROMP-speech) into the Arabic language among Lebanese subjects with dysarthria., Materials and Methods: This study included 50 participants with dysarthria. The Arabic versions of the RDA (A-RDA) and the ROMP-speech (A-ROMP-speech) were administered in addition to the Arabic Speech Intelligibility test, the Lebanese Voice Handicap Index-10 (VHI-10lb) and semantic verbal fluency tasks. The maximum performance tasks were analyzed using the Praat software. The A-RDA qualitative recording form and the A-ROMP-speech were assessed for construct validity and internal consistency. The convergent validity of the maximum performance tasks, the severity scale, and the A-ROMP-speech were evaluated., Results: Exploratory factor analysis of the qualitative recording form extracted 3 factors explaining 82.973% of the total variance, and it demonstrated high internal consistency (α = 0.912). The maximum performance tasks of the RDA correlated significantly with the corresponding Praat scores. The severity scale and the A-ROMP-speech correlated fairly to strongly with the Arabic Speech Intelligibility test (r s =-0.695 and -0.736, p  < 0.001) and the VHI-10lb ( r  = 0.539 and 0.640, p  < 0.001)., Conclusion: The A-RDA and the A-ROMP-speech are valid and reliable dysarthria tools among Lebanese subjects.

Background: Non-progressive dysarthria is an acquired motor speech disorder resulting from neurological diseases such as stroke and traumatic brain injury. The evidence base for the assessment of non-progressive dysarthria remains limited with professional practices relying mainly on therapists' clinical experience. Limited information on the assessment practices of Lebanese speech and language therapists (SLTs) is available. Such information is crucial for the development of adequate therapy services for clients with non-progressive dysarthria. This study aims to explore the assessment practices and attitudes of Lebanese SLTs working with adults with non-progressive dysarthria and to investigate their adherence to the framework of the World Health Organization's International Classification of Functioning, Disability and Health (ICF)., Methods: A cross-sectional study was conducted in Lebanon between March and May 2021. Data was collected through an online survey that included information on socio-demographic characteristics, practices, and attitudes of SLTs who assess adults with non-progressive dysarthria., Results: A total of 50 Lebanese SLTs responded to the survey. The majority of SLTs (78%) assessed clients with non-progressive dysarthria across all ICF domains. SLTs reported dissatisfaction with the available assessment tools (64%) and reliance on informal tools (84%). In addition, 68% of the SLTs suggested the crucial need for the development of Arabic formal assessments that can quantitatively evaluate dysarthria and determine severity. The survey also showed that the respondents demonstrated a preference for the use of impairment-based tools., Conclusion: It can be concluded that the assessment practices of Lebanese SLTs, generally, follow the international trend and the recommended professional guidelines. Further research initiatives should be held to develop Arabic formal assessment tools for non-progressive dysarthria., (© 2021. The Author(s).)
