Cross Cultural Adaptation and Validation of Kannada Version of the Motivation in Stroke Patients for Rehabilitation Scale in Hospitalized Stroke Patients

Objective Stroke survivors are frequently described as apathetic, lacking interest, and having poor motivation, which might hinder treatment outcomes. A Japanese version of the motivation in stroke patients for rehabilitation (MORE) scale was developed to evaluate the motivation level of stroke patients and was translated into an English version by the original author. The following study aimed to cross-culturally adapt and validate the Kannada (local language) version of the MORE scale in stroke patients. Material and Methods A structured scale translation procedure was performed by a linguistic expert fluent in English and Kannada in accordance with the stages for linguistic validation. The translation procedure involved forward translation, backward translation, final correction, and preliminary pilot testing. The final cross-culturally adapted Kannada version of the MORE scale was obtained, and validation was evaluated based on criterion validity using Pearson’s correlation test. Statistical significance was set at p-value < 0.05. Data were analysed using the SPSS software (SPSS Inc., Chicago, IL, USA) version 29.0.10. Results There was a positive correlation (p < 0.05) between the total score of the English and Kannada versions of the MORE scale with a Pearson correlation coefficient of r = 0.995 and an intra-class correlation coefficient of ICC = 0.998 (95% CI for ICC = 0.996-0.998). Conclusion The Kannada version of the MORE scale has been culturally adapted to assess motivation among the Kannada-speaking population and is a valid tool for assessing motivation among individuals with stroke.
