The aim of this paper is to provide a preliminary analysis of the reliability and validity of the Aural Rehabilitation Outcome Profile questionnaire (PIRS). This self-assessment questionnaire is used to quantify functional hearing difficulties in adults in regards to factors such as acoustic environment and interlocutor features (parts 1, 3, and 5), frequency of occurrence of different compensating communication strategies, and severity of socio-emotional consequences of acquired hearing loss (part 4), influence of acquired hearing loss (AHL) on everyday activities (part 2), and hearing aid performance and user satisfaction (part 5). An analysis of the reliability and validity of each individual part/scale of PIRS was conducted on data obtained from 47 adult participants (37 hearing aid users and 10 normal hearing individuals), including the analysis of Cronbach's reliability coefficients and intraclass correlation coefficients, factor analysis, and the Mann-Whitney U for testing the self-assessment differences between hearing participants and those with hearing loss as well as correlation analysis between hearing loss degree and self-assessment results. The results indicated that all PIRS subscales/parts show the properties of reliability and validity, warranting additional examination of psychometric properties with the goal of assessing the suitability of using PIRS as a clinical outcome measure of aural rehabilitation for acquired hearing loss.
