A French foot health survey showed that 73% of people examined felt pain and 38% don't left their home, which suggest a reduction in their life's quality and autonomy. Developed by Paul Bennett, FHSQ is a foot health-specific self administrated questionnaire. It sensitively detects changes in patients' foot health status, whatever their pathology, across multidimensional concepts of their quality of life. Actually, more than 150 scientific publications have cited it. Reliable and valid, it has already been translated and validated in multiple languages, but not in French. The subject of this study is to validate the translated and cross-cultural adapted French version FHSQ-fr through its psychometric results of validity and reliability. The study follows a 2-stage methodology. The first, already completed, consisted of (back)translating the Australian FHSQ questionnaire into French by a scientific committee in order to obtain a pre-final version. The second is to validate this final version using appropriate statistical analysis, including correlations studies with other French validated questionnaires, to determine its psychometric characteristics.
To assess validity, 150 volunteers will fill out French validated questionnaires, Foot Function Index (FFI), EuroQuality of life 5D-5L (EQ5D) , Visual Analogic Pain Scale (VAPS), and Short Form 12 Health survey (SF12). They will be evaluated about their pain, morphology, function and posture of their feet as usual at a podiatric school. To assess reliability, 50 respondents from the 150 who didn't receive any treatment after 7 to 10 days, will complete the FHSQ-fr again. It would improve knowledge of the status of foot health and its related quality of life in the general population and those suffering from specific pathologies such as diabetes or rheumatoid arthritis, the effectiveness of certain treatments on the same foot condition, and their evolutions using longitudinal studies in France. At the international, the French future results of studies using this clinimetric tool could be compared with those who come from other countries, and integrated to the Australian author's " Bigdataset" which compares, analyses and predicts more accurately the clinically significant efficacy of a treatment.

RECRUITINGInternal consistency
It is evaluated using Cronbach's alpha coefficient "α", which measures the internal consistency of a set of items, scales or sub-scales for a single clinical dimension. The value of this index is less than or equal to 1, and the closer alpha is to 1, the stronger it is. α" \> 0.7 or \>0.8 is considered fairly high. However, the coefficient must not be too close to 1, otherwise the items are redundant and duplicate each other.
Time frame: Day 0
Temporal stability of patients' questionnaire scores FHSQ-en V 1.02
It is measured by the Intraclass Correlation Coefficient (ICC) and its 95% confidence interval, and/or the Pearson Correlation Coefficient. By convention, fidelity is said to be: * Very good if ICC ≥0 91 * Good if 0.9 ≤ ICC ≤ 0.71 * Moderate if 0.70 ≤ ICC ≤ 0.51 * Poor if 0.5 ≤ ICC ≤ 0.31 * Very poor or nil if ICC ≤ 0.3
Time frame: Day 0 and day 7
Measurement error
To apply the criterion of good measurement error, the MIC (Minimal Important Change), the SDC (Smallest Detectable Change) or the LoA (Limits of Agreement) load will be calculated using a longitudinal approach based on anchoring.
