Application of the Rasch Model to Develop a Simplified Version of a Multiattribute Utility Measurement on Attitude Toward Labor Epidural Analgesia

Abstract

We demonstrated application of the Rasch analysis to simplifying a multiattribute utility questionnaire without compromising reliability. Further study is necessary to determine whether the simplified questionnaire is valid for use in clinical practice.

The Screen for Cognitive Impairment in Psychiatry: Proposal for a polytomous scoring system

“…Rasch analyses are increasingly being applied to various tests in the health field, for example, scales that measure psychological distress (Khan, Chien, & Burton, ), anxiety and depression (Parkitny et al, ), self‐harm (Latimer, Covic, Cumming, & Tennant, ), catatonia (Wong, Ungvari, Leung, & Tang, ), quality of life (Da Rocha & De Almeida, ), attitudes (Chang, Tsou, Chan, & Chen, ), and sleep patterns (Meltzer et al, ), among many others. The advantage of the Rasch model, in addition to the inherent strengths of an item response theory approach, is that it has been shown to be robust even when sample sizes are small and test lengths are short, both of which are common scenarios in the health field.…”
