Turkish Cross-cultural Adaptation, Validity, Reliability, and Responsiveness of the Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) in Patients With Hip Osteoarthritis
調査の概要
詳細な説明
## Detailed Description
Hip osteoarthritis (HOA) is one of the leading causes of pain, disability, and reduced health-related quality of life among older adults worldwide. Patient-reported outcome measures (PROMs) are essential for evaluating symptoms, functional limitations, treatment effectiveness, and patient-centered outcomes in both clinical practice and research. The Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) is a concise, multidimensional PROM developed to assess pain, physical function, and hip-related quality of life while substantially reducing respondent burden compared with the original HOOS questionnaire.
Although the HOOS-12 has been validated in several languages and populations, no culturally adapted and psychometrically validated Turkish version is currently available. The absence of a validated Turkish HOOS-12 limits its use in clinical practice, multicenter studies, and international research involving Turkish-speaking patients with hip osteoarthritis. Therefore, a rigorous cross-cultural adaptation and psychometric evaluation is required before the instrument can be recommended for clinical and research applications in Türkiye.
The primary objective of this study is to translate and culturally adapt the HOOS-12 into Turkish and to evaluate its psychometric properties in patients with hip osteoarthritis who are scheduled to undergo primary total hip arthroplasty. The translation and cross-cultural adaptation process will be conducted in accordance with internationally accepted guidelines for patient-reported outcome measures, including forward translation, synthesis, backward translation, expert committee review, and pilot testing to ensure semantic, idiomatic, experiential, and conceptual equivalence between the original and Turkish versions.
Following the adaptation process, the psychometric performance of the Turkish HOOS-12 will be evaluated according to the COSMIN recommendations. Internal consistency will be assessed using Cronbach's alpha, while test-retest reliability will be examined using the intraclass correlation coefficient (ICC) in clinically stable participants who complete the questionnaire twice before surgery without any therapeutic intervention between assessments. Measurement error will be determined by calculating the standard error of measurement (SEM) and the minimal detectable change (MDC). Structural validity will be evaluated using confirmatory factor analysis (CFA). Construct validity will be examined by testing predefined hypotheses regarding the relationships between the Turkish HOOS-12 and the Short Form-12 Health Survey (SF-12). Floor and ceiling effects will also be investigated.
To determine responsiveness, participants will complete the Turkish HOOS-12 and SF-12 before surgery and again three months after primary total hip arthroplasty. Changes in questionnaire scores over time will be analyzed to evaluate the instrument's ability to detect clinically meaningful improvement following surgical treatment.
The results of this study are expected to provide a reliable, valid, and responsive Turkish version of the HOOS-12 for evaluating patient-reported outcomes in individuals with hip osteoarthritis. The availability of this instrument will facilitate standardized outcome assessment in routine clinical practice, clinical trials, and multicenter research involving Turkish-speaking populations.

Patients with Hip Osteoarthritis
Adults with clinically and/or radiographically diagnosed hip osteoarthritis who are scheduled to undergo primary total hip arthroplasty.
Participants will complete the Turkish version of the Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) and the Short Form-12 Health Survey (SF-12) before surgery.
A subset of clinically stable participants will complete the HOOS-12 again after 7 days for test-retest reliability assessment.
Participants will also complete the HOOS-12 and SF-12 three months after surgery to evaluate responsiveness.
|
Participants will complete the Turkish version of the Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) and the Short Form-12 Health Survey (SF-12) at predefined assessment time points.
No therapeutic intervention will be assigned or administered as part of this observational study.
Primary total hip arthroplasty will be performed as part of routine clinical care and will not be assigned by the investigators.

Internal Consistency of the Turkish HOOS-12
時間枠：Baseline
|
Internal consistency of the Turkish Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) will be assessed using Cronbach's alpha coefficient.
The HOOS-12 is a 12-item patient-reported outcome measure assessing hip-related pain, physical function, and hip-related quality of life.
The HOOS-12 summary score ranges from 0 to 100, where 0 represents the worst possible hip-related health and 100 represents the best possible hip-related health.
Higher scores indicate better hip-related health.
Internal consistency will be evaluated using baseline data.

Test-Retest Reliability
時間枠：Baseline and Day 7
|
Test-retest reliability of the Turkish Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) will be assessed in clinically stable participants who complete the questionnaire at baseline and again on Day 7. The HOOS-12 summary score ranges from 0 to 100, where 0 represents the worst possible hip-related health and 100 represents the best possible hip-related health.
Higher scores indicate better hip-related health.
Test-retest reliability will be evaluated using the intraclass correlation coefficient (ICC).
Participants with a substantial therapeutic intervention or clinically relevant change in their condition between the two assessments will not be included in the test-retest reliability analysis.

Construct Validity With SF-12 Physical Component Summary
時間枠：Baseline

Construct validity of the Turkish Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) will be evaluated by examining the correlation between the HOOS-12 summary score and the Physical Component Summary (PCS) score of the 12-Item Short Form Health Survey (SF-12), according to a predefined hypothesis.
Higher scores on both measures indicate better health status.

Construct Validity With SF-12 Mental Component Summary
時間枠：Baseline
|
Construct validity of the Turkish Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) will be evaluated by examining the correlation between the HOOS-12 summary score and the Mental Component Summary (MCS) score of the 12-Item Short Form Health Survey (SF-12), according to a predefined hypothesis.
Higher scores on both measures indicate better health status.

Structural Validity
時間枠：Baseline
|
Structural validity of the Turkish Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) will be evaluated using confirmatory factor analysis (CFA).
The HOOS-12 consists of 12 items assessing hip-related pain, physical function, and quality of life.
The HOOS-12 summary score ranges from 0 to 100, where 0 represents the worst possible hip-related health and 100 represents the best possible hip-related health.
Higher scores indicate better hip-related health.
Model fit will be evaluated using the Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA), and Standardized Root Mean Square Residual (SRMR).
CFI, TLI, RMSEA, and SRMR will be interpreted jointly as complementary model-fit indices to evaluate the overall fit of the prespecified measurement model rather than as separate outcome measures.
