Translation, cross-cultural adaptation and validation of the Brazilian version of the Nonarthritic Hip Score

Abstract

CONTEXT AND OBJECTIVE: The Nonarthritic Hip Score (NAHS) is a clinical evaluation questionnaire that was developed in the English language to evaluate hip function in young and physically active patients.

Patient-Reported Outcome (PRO) questionnaires for young to middle-aged adults with hip and groin disability: a systematic review of the clinimetric evidence

“…The other studies, including: modified Harris Hip Score (mHHS) in three studies,11 35 40 Hip disability and Osteoarthritis Outcome Score (HOOS) in two studies,11 40 Non-Arthritic Hip Score (NAHS) in three studies,31 37 40 Hip Sports Activity Scale (HSAS) in one study,44 Super Simple Hip Score (SUSHI) in one study39 and Western Ontario and McMaster Universities Osteoarthritis Index—12 (WOMAC-12) in one study36 had either no evaluation of their methodological quality concerning content validity specifically for young-aged and middle-aged patients, or a poor rating on this aspect. Furthermore, structural validity was either not assessed, or displayed poor methodology in all these studies, except in the study using WOMAC-12 36.…”

“…HOOS, HOS, IHOT-12, IHOT-33 NAHS and WOMAC-12 all scored indeterminate ratings for internal consistency. This was due to a lack of appropriate factor analysis and/or missing Cronbach's α for each subscale in most of the studies investigating these clinimetric properties for these PROs 11 12 31 32 37 38 42 43 45 46…”

“…All PROs except HSAS, NAHS and WOMAC-12 scored a positive rating for construct validity. Indeterminate ratings for HSAS and NHAS were given based on a lack of information concerning a priori hypotheses, and WOMAC-12 was not assessed for construct validity 31 36 37 44…”

“…Information on test–retest reliability was found for eight questionnaires of which all had a positive rating 12 14 34 37 38 40–44 47. No test–retest reliability results were available for SUSHI and WOMAC-12 36 39…”

Validation of the Brazilian version of the Hip Outcome Score (HOS) questionnaire

“…The study protocol included completing the identification form, which was composed of the clinical characteristics of the patients and the application of three quality of life assessments: the HOS-Brazil as well as the Brazilian-validated versions of 12-Item Short-Form Health Survey (SF-12) and the Nonarthritic Hip Score (NAHS) [16,18,19]. The participants were instructed to complete all three questionnaires (1st application or test).…”
