Abstract

Extended psychometric analysis was done using the factor analysis (Horn´s Parallel Analysis, Exploratory Factor Analysis) and Rasch analysis (RA, Rating Scale model) (Scale diagnostic, Validity, Reliability, Dimensionality and Local independence, Differential item functioning (DIF)). Results: Horn´s Parallel Analysis revealed one factor (loading factor > 0.40). RA showed a correct functioning of the rating categories of the scale. As for the item fit, only one item 'It is easy to put on my device' slightly underfitted the model (Outfit MSQ = 0.720, Infit MSQ = 0.650) and item 'durability' overfitted the model (Outfit MSQ = 1.378, Infit MSQ = 1.291). The study showed a few similar allocations of items along the logit scale, weight and fit was easy to endorse, whereas the look and comfort of the orthosis were difficult to agree with. No local dependency was detected. The targeting of item difficulty to the patient ability was good. Omega reliability value of CSD-Sk was 0.9 (polychoric Cronbach's alpha level 0.9). No DIF was detected. ConClusions: Despite some limitations in terms of fit, psychometric properties of CSD-Sk are in line with previous analyses on the English, Swedish and Italian version of the tool.
