Further psychometric evaluation of the Swedish version of the Interdisciplinary Education Perception Scale (IEPS) using Rasch analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe Interdisciplinary Education Perception Scale (IEPS) is an instrument that measures students’ perceptions of interprofessional learning. It has shown satisfactory internal consistency for the total scale; however, problems regarding the psychometric properties of the subscales have resulted in several different versions of the instrument. The aim of this study is to further evaluate the psychometric properties of the Swedish version of IEPS using Rasch analysis.
methodsThe Swedish translation of the 12-item, 3 subscale version of the IEPS was used in a student population (n = 704) from eight healthcare programmes. The psychometric properties were evaluated using Rasch analysis based on five aspects: rating scale functioning, unidimensionality, reliability, targeting, and differential item functioning.
resultsThe total scale showed satisfactory internal consistency. However, the scale was suboptimal regarding the response categories, where three response categories had to be combined into one to achieve a more optimal number of observations per category. Regarding the second subscale, Perceived need for cooperation, item 4 and particularly item 6 showed local dependency and disordered thresholds.
conclusionTo improve the evaluation of interprofessional education, future research should rephrase the response categories or minimize the number of response options. Additionally, the removal of item 6 and possibly item 4 from the second subscale may improve the psychometric properties of the scale.
