Aims: The Participation Scale (P-Scale) is a widely used generic self-report measure designed to assess an individuals participation restriction consequent to any disease condition. The present study aimed to evaluate the validity and reliability of a south Indian (Kannada language) version of the P-Scale for use with adults with hearing loss. This study is a part of an ongoing research program on the assessment of outcomes of hearing health rehabilitation with hearing aids involving Indian client groups. Methods: One hundred and three adults with hearing loss completed the original English and the newly translated-adapted Kannada P-Scale questionnaire. Nearly half of the participants completed repeat testing of the Kannada version 15 days after the initial assessment. Along with the P-Scale, Kannada versions of the Hearing Handicap Questionnaire (HHQ) and the Assessment of Quality of Life - 4 Dimensions Questionnaire (AQoL-4D) were also administered. Based on predefined quality criteria, five different psychometric properties of the P-Scale were evaluated, together with an analysis of the Kannada P-Scales factor structure. The psychometric properties assessed included internal consistency, test-retest reliability, convergent validity, discriminant validity, and floor-ceiling effects. Results: Principal component analysis indicated a four-factor complex structure, which explained 69.78% of the variance in the Kannada P-Scale. High internal consistency (Cronbachs alpha = 0.90) and test-retest reliability (internal consistency coefficient amp;gt;0.90) were obtained. Comparisons with the HHQ (rho = 0.52) and AQoL-4 D (rho = 0.76) indicated good convergent validity. Discriminant validity among the P-Scale questions was acceptable (inter-item correlation amp;lt;0.60). Floor and ceiling effects were not evident in the Kannada P-Scale. Conclusions: The psychometric characteristics of the Kannada P-scale were found to be sufficient for use with the participant group (literate, Kannada-speaking adults with hearing loss) who were assessed in this study. Further research is required to determine generalizability of the Kannada P-Scale among other Kannada-speaking communities.
