All OA patients had radiographs of their affected joints. The Lequesne Algofunctional Indexes for severity of OA Radiographs of the knees were anteroposterior AP of the hip LAI-hip and knee LAI-knee each consist of three weight-bearing, semiflexed view, whereas an AP pelvis sections with a total of 11 questions: severity of pain five radiograph was collected on hip patients. The radiographs items , walking ability two items and physical function four used in this study were generally obtained within 1 year items.

A the hip LAI-hip and knee LAI-knee include three sections Rasch analysis evaluates the psychometric properties of a which are not graded separately and take a few minutes to questionnaire that are not analysed by CTT techniques, e. Rasch analysis is being increasingly used in the walking aids as an 11th question item 6b in Tables 1 and 2 development and evaluation of clinical tools for health care, [17, 18].

For the purposes of this study we chose to use the and the advantages of this approach have been documented self-administered format because in clinical trials it allows for in the literature [26, 27]. The aim of this study was to mailing to patients. Both Lequesne indexes are scored as the perform a comprehensive psychometric analysis of both sum of all items, resulting in a total score ranging from 0 to LAI-hip and LAI-knee, using both CTT and Rasch analysis, Higher scores denote greater OA severity.

Statistical analysis Patients and methods A stage process was used to investigate the basic properties of LAI-hip and LAI-knee: Patients and data collection Internal consistency and dimensionality In this cross-sectional survey, the disease-specific LAI-hip and LAI-knee questionnaires were completed by 1, patients The items were examined for internal consistency calculating: with symptomatic OA of the knees patients or hips patients , enrolled by general practitioners participating in the 1.

After a review of the rating scale categories, the Rasch analysis validity was analysed by evaluating the fit of individual items of each index LAI-hip and LAI-knee to the latent After the above analysis, the matrix of single raw trait as per the Rasch modelling unidimensionality and scores for each subject underwent Rasch analysis examining if the pattern of item difficulties was consis- partial credit model through the WINSTEPS software, tent with the model expectation.

If necessary, according to the findings square analysis to test if there were items which did not of the rating scale diagnostic, categories were collapsed fit with the model expectancies [23].

The internal it might be appropriate to simplify the item format. In addition, the use mentioned that among all the questions this was the least of the raw score seems inappropriate because items have comprehensible [39].

As for the fit of individual items to very different rating points, not properly weighted. The most used approaches are derived from underfitting.

This indicates that both LAI scales have the factor analysis: EFA is used to study the relevant latent items that either do not tap the same underlying construct factors after some form of estimation of their number and or are poorly written or too sensitive to confounding the contribution of individual items to those traits in new or factors.

For example, it is reasonable that unexpected modified models e. In any case, we think that an instrument for examining information over that provided by other items in the scale, the severity of hip and knee OA should separately rate and with a response pattern too predictable from the overall functional difficulty and functional pain [41].

This inter-item dependency indicates that Minosi Armando, Miserocchi Fabio, Moreno Mauro, Muratore either they duplicate some feature of each other or they Maurizio, Murgo Antonella, Ortolani Sergio, Olivieri Ignazio, Paolazzi both incorporate some other shared dimension.

Moreover, if some items are removed, this could reduce the breadth, precision and reliability of both scales. Disclosures None Our study has a number of limitations.
