Comparison of measures to assess outcomes in total hip replacement surgery. The results of our study, in our opinion, provide evidence supporting the superiority of the LEFS over the SF for assessing lower-extremity function.

One approach to overcoming the need for multiple measures of health status in clinical practice is to explore whether the measurement properties of conditionspecific measures are superior to those of generic measures.

Pearson correlations and one-way analyses of variance were used to examine construct validity. The ratings were performed allowing discussion of the patient profile, and a single agreed-on score was determined. In a previous study, 24 we observed that the LEFS questionnaire shows a strong correlation with the Lequesne Index and also with WOMAC, confirming its validity as a clinical tool for the analysis of functional impairment in elderly patients with OA.

The oefs sites represented in this group of patients were: Each subscale score can vary from 0 towith higher scores representing more desirable health states.

The inclusion criteria were: A description of the patients is presented in Table 1. The Qeustionnaire is efficient to administer and score and is applicable for research purposes and clinical decision quesyionnaire for individual patients. Evaluating changes in health status: Add comment Close comment form modal. An external standard of change was introduced to examine the extent to which a health status measure truly differentiates among patients who have improved, deteriorated, or remained stable and subsequently used in our study and by other authors.

In the absence of an accepted measure of function, determination of the validity of functional scales has relied heavily on the concept of construct validity. Results – 1, individuals fulfilled the inclusion criteria and were included in the study. You have entered an invalid code. In this case, depending on the clinical picture and time frame since the previous assessment, a change in intervention, referral, or discharge of the patient may be considered.

Participants who were unfit for work had worse scores. At the individual item level, mean score, median score, standard deviation, range, and frequency of endorsement of each level 0—4 of all items were determined.
