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

Abstract

Background: The Hip Outcome Score (HOS) was developed to evaluate physically active patients with hip disease but without severe degenerative change. A translation and cultural adaptation into Brazilian Portuguese was previously conducted. The aim of this study was to validate the Brazilian version of the HOS (HOS-Brazil) among a group of physically active patients with a diagnosis of femoroacetabular impingement (FAI) or greater trochanteric pain syndrome (GTPS). Methods: The following questionnaires were applied: the HOS-Brazil; the validated Brazilian versions of the Nonarthritic Hip Score (NAHS) and the 12-Item Short-Form Health Survey (SF-12). The psychometric properties analyzed with regard to the validation process were reliability and validity. Internal consistency and intra-rater testretest reliabilities were analyzed using Cronbach's alpha and the intraclass correlation coefficient (ICC) statistical tests based on test-retest agreement. Construct and content validities were examined using Pearson's correlation coefficient. Content validity was also analyzed based on evidence of floor, ceiling, or both types of effects from the questionnaires. Results: A total of 70 male and female patients were selected, aged between 19 and 70 years old. The internal consistency and intra-rater test-retest reliability values were high (Cronbach's α > 0.9; ICC > 0.9). The questionnaire showed acceptable convergent (r > 0.7) and divergent (r < 0.4) validities. No floor or ceiling effects were observed. Conclusion: The HOS-Brazil was validated. Additional studies are underway to evaluate its responsiveness.

Outcome measures in the management of gluteal tendinopathy: a systematic review of their measurement properties

“…The test–retest reliability was reported in a single study and found to be 0.99 (95% CI 0.99 to 1.00) for the HOS-Brazil (ADL) and 0.99 (95% CI 0.99 to 1.00) for the HOS-Brazil (Sport) 23. The HOS-Brazil subscales (ADL and Sport) were rated down due to indirectness, as the study included patients without gluteal tendinopathy (37% had femoroacetabular impingement), and one level for both risk of bias and imprecision (n<100) 23. Overall, there was very low-quality evidence of sufficient test–retest reliability of the HOS-Brazil (ADL) and the HOS-Brazil (Sport) (table 3).…”

“…One study reported the minimal detectable change of the HOS-Brazil (ADL) and HOS-Brazil (Sport), which were 4.71 and 5.27, respectively (table 4). 23 The minimal important change of the HOS-Brazil (ADL) and (Sport) in patients with gluteal tendinopathy was 4.6 and 5.5, respectively 23. Overall, there was very low-quality evidence that the measurement error of the HOS-Brazil (ADL) was insufficient and very low-quality evidence that the measurement error in the HOS-Brazil(Sport) was sufficient.…”

“…One study reported on measurement properties of the HOS-Brazil activities of daily living (ADL) and Sport subscales, which included 70 participants, of which 44 had gluteal tendinopathy (26 had femoroacetabular impingement) and had a mean age of 43 23…”

“…None of the translations of the VISA-G17 19 20 22 or HOS-Brazil (ADL) or (Sport) subscales23 underwent cross-cultural validation, which requires the assessment of measurement variance across different populations 7. Subsequently, the cross-cultural validity of the Danish, French, Italian and Brazilian Portuguese versions of the VISA-G and the HOS-Brazil (Sport and ADL) was rated indeterminate.…”
