Abstract

Introduction

To evaluate the effectiveness of new treatments, whether conservative or surgical, a self-administered questionnaire for hip pain targeted at physically active patients 18 to 60 years of age, named the international Hip Outcome Tool-33 (iHOT-33), was developed and validated in 2012. Since there is no French version available and we are acutely aware of transcultural variations, we conducted a prospective study to: 1) translate, and then 2) validate this questionnaire into international French.

Hypothesis

The iHOT-33-Fr questionnaire is a valid and reliable tool for evaluating hip pain in a young, francophone population.

Materials and methods

Translation of the questionnaire was done according to the standardized method described by Beaton and the final version of the iHOT-33-Fr was validated using the COSMIN methodology. The data were collected prospectively at multiple sites. The reliability of the iHOT-33-Fr questionnaire was evaluated using the intraclass correlation coefficient (ICC) and its internal consistency using Cronbach's alpha. The standard error of measurement and minimum detectable change were calculated. The construct validity was evaluated using Pearson's correlation coefficient by comparing the iHOT-33-Fr with the Hip disability and Osteoarthritis Outcome Score (HOOS-Fr) and Nonarthritic Hip Score (NAHS-Fr).

Results

In all, 101 patients filled out the questionnaires. The ICC was 0.87. The Cronbach alpha was 0.95. The standard error of measurement was 6.4 and the minimum detectable change was 1.8. The correlation between the iHOT-33-Fr and the HOOS-Fr was 0.86, while the correlation between the iHOT-33-Fr and the NAHS-Fr was 0.75.

Discussion

Our results show that the metrological qualities of the iHOT-33-Fr are comparable to those of the original version and the versions translated into other languages. This study demonstrates that the iHOT-33-Fr is valid, reproducible and comparable to the original iHOT-33. It can be used by francophone surgeons treating symptomatic hip disease in young, active patients.
