Abstract

Background: A number of tools are used for measurement of severity of Rhinology and Otology related disorders and their impact on Quality of Life. The tools differ in terms of length (number of items), width (number of response-categories/levels), dimensions covered, psychometric documentation and scores are not comparable.

Objectives: To address methodological issues of tests and suggests remedial measures by transforming ordinal item scores to follow normal distribution for meaningful evaluation of measurement properties and better utilization of such tests.

Methods: Using data-driven weights to response-categories of different items, ordinal item scores are converted to equidistant score (E-scores) in ratio scale with fixed zero point. Proposed scores (P-scores) are obtained from E-scores via linear transformations lie between 1 and 100 following normal distribution. Dimension scores and test scores are taken as sum of item-wise P-scores which also follow normal with parameters obtained from data

 Results: Normally distributed P-scores satisfy the basic assumption of statistical techniques and offer platform for parametric analysis facilitating meaningful arithmetic aggregation, meaningful comparisons and better utilization of such tests. It also help to find reliability as per theoretical definition, factorial validity avoiding criterion variable, assessment of responsiveness, optimal number of clusters and efficiency of classification, equivalent scores of two tests, etc.

Conclusion: Proposed scores following normal and satisfying desired properties of measurement is recommended. Experts and researchers can derive benefits of the proposed score for better comparisons and prognosis.
