Refinement and Validation of the Social Participation Restrictions Questionnaire: An Application of Rasch Analysis and Traditional Psychometric Analysis Techniques

Conclusions: This was one of the first studies to devise a new hearing-specific outcome measure using Rasch analysis. Rasch analysis proved to be a powerful technique for supporting decisions regarding which items to retain in order to achieve a psychometrically robust questionnaire. Additional support for the robustness of this questionnaire came from the utilization of traditional psychometric analysis techniques. Therefore, this questionnaire has the potential to be used in research and clinical practice to evaluate whether auditory rehabilitation interventions improve social participation in adults with hearing loss. The next stage of this research will be to further validate this questionnaire by assessing its responsiveness in a clinical population. The combined use of modern and traditional psychometric analysis techniques should be considered in future questionnaire development and validation research.
