Implication

Rasch analysis improves measurement precision of self-reported outcomes in rehabilitation, indicating more accurate patient assessments.

Key Points

The aim is to enhance the development of self-reported outcome measures (SROMs) for assessing physical function using Rasch analysis.
Introduced Rasch analysis as a framework for SROM development.
Illustrated application to dichotomous and polytomous data.
Explained transformation of ordinal scores into interval-level measurements.
Presented outputs like category probability curves and person–item maps.
Converted ordinal scores to valid interval-level measures.
Improved targeting and measurement precision across different ability levels.
Identified item bias, misfit, and ceiling effects in functional assessments.
