For content validity, I-CVI and S-CVI ranged from 0.80-1 to 0.90-1, respectively. To assess the reliability and clinically meaningful thresholds of intermittent and constant osteoarthritis pain (ICOAP) score, the Knee injury and Osteoarthritis Outcome Score Physical function Short-form (KOOS-PS), the Hip disability and Osteoarthritis Outcome Score Physical function Short-form (HOOS-PS), and the Quality of life subscales of HOOS/KOOS (HOOS-QOL/KOOS-QOL) … Further, these instruments demonstrated a high level of responsiveness, with effect sizes and standard response means of greater than 0.80. Knee Injury Osteoarthritis Outcomes Survey (KOOS) activities of daily living (ADL) improved at 6 weeks and 3 months postsurgery with preoperative physical therapy. Comparative, validity and responsiveness of the HOOS-PS and KOOS-PS to the WOMAC physical function subscale in total joint replacement for osteoarthritis. Validity shows how a specific test is suitable for a particular situation. For validation, the KOOS was tested on 58 patients diagnosed with OA. Reliability was tested using the intraclass correlation coefficient (ICC). Original full-text published studies were considered for inclusion, as well as PhD theses identified by the search strategy. Download. Content Validity for participants with ACL and meniscus injury, and early OA a literature review was conducted, a panel of experts was consulted and a pilot study was conducted (Roos and Toksvig-Larsen, 2003) The purpose of our study; Turkish reliability and validity of the Knee Osteoarthritis and Knee Injury and Osteoarthritis Result Score-12 scale. However, there was a lack of satisfactory evidence of structural validity for ICOAP and KOOS. adaptation guidelines. Thus, a preliminary KOOS-Child was developed. READ PAPER. Objective. The properties of the KOOS in terms of reliability [Intraclass Correlation Coefficient (ICC)], internal consistency (Cronbach’s alpha), dimensionality (item–scale correlation) and construct validity (Spearman’s rank correlation) were evaluated.ResultsNo floor or ceiling effect was observed. Recent data indicate a lack of comprehensibility when this is used with children. The short form of KOOS-12 was found to be a valid and reliable scale in individuals who underwent total knee arthroplasty. This paper. In comparison to the WOMAC, the KOOS improved validity and may be at least as responsive as the WOMAC. Rheumatol Int 2013; 33(10): 2691-4. Results: For construct validity, moderate Pearson correlation coefficients were found between the KOOS subscales and the SF-36. Find it on PubMed. If the method of measuring is accurate, then it’ll produce accurate results. Inter-rater reliability for the 65 cohort studies across the NOS items is presented in Table 1.Reliability was slight (i.e., K of 0.00 to 0.15) for the majority of items (representativeness of the exposed cohort, selection of the non-exposed cohort, demonstration that outcome of interest was not present at the start of study, comparability of cohorts, and adequacy of follow-up of cohorts). The OKS-Ar effect size was 3.09, which was larger than that of all of the KOOS subscales at 6 months after TKA. Construct validity was evaluated by quantifying the correlation between the KOOS and the Japanese van Hedel, H. J., Wirz, M., et al. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory. Results: Test–retest reliability of 6 MWT in primary OA knee patients was excellent with ICC 0.991 (95% confidence interval was 0.986–0.994). Purpose. Reliability and Validity of Turkish Version of Knee Injury and Osteoarthritis Outcome Score-12 (KOOS-12) Latest version (submitted February 18, 2021) on ClinicalTrials.gov A study version is represented by a row in the table. J Orthop Sports Phys Ther 2013;43 (1):20–28. Cronbach's alpha coefficient was 0.89 and intraclass correlation coefficient (ICC) was 0.85, certifying that KOOS-PS reliability was acceptable. Cronbach α was 0.84 to 0.97 for all subscales, indicating adequate internal consistency. Osteoarthritis and Cartilage, 17(7), 843-847. Two hundred and twenty-six knee OA patients attending the Outpatient and Orthopaedic Clinics, Universiti Sains Malaysia Hospital, completed the Malay version KOOS. and excellent reliability being respectively indicated by values of 0.70e0.85 and >0.8515). Osteoarthritis and … Reliability of KOOS. The OKS-Ar pain component correlated strongly with the KOOS-Ar pain subscale (r s = 0.73). to-high construct validity with existing validated self-report measures. (2005). Overall, both questionnaires Construct validity using confirmatory factor analysis and internal reliability assessment were performed. Results: For construct validity, moderate Pearson correlation coefficients were found between the KOOS subscales and the SF-36.

Internal consistency (Cronbach alpha), test-retest reliability (intraclass correlation coefficient [ICC]), measurement error (SEM), smallest detectable difference (SDD), content validity, construct validity (factor analysis and hypothesis testing), and floor and ceiling effects were determined. Internal consistency (Cronbach alpha), test–retest reliability (intraclass correlation coefficient [ICC]), measurement error (SEM), smallest detectable difference (SDD), content validity, construct validity (factor analysis and hypothesis testing), and floor and ceiling effects were determined. Sabina Sharma. KOOS has been found to be a valid, reliable and respon- sive outcome measure in different patient populations with varying knee injuries (of menisci, ACL or cartilage) Reliability. This tool was developed initially to use on adults. The KOOS pschometric properties have shown high reliability and validity, and is responsive to change in subjects with knee degeneration or knee injury. The ADL subscale has better content validity for older patients and Sport/Rec for younger patients with knee injuries, while the Pain subscale is more relevant for painful knee conditions. The Knee injury and Osteoarthritis Outcome Score (KOOS) is a valid, reliable, and responsive outcome measure in total joint replacement. Conclusions: To our knowledge, this is the first study to assess reliability, validity, and responsiveness of the OKS-Ar after TKA. The secondary aim was to examine the suitability of the F-KOOS in terms of relevance and ease of understanding the tool. KOOS has been found to be a valid, reliable and responsive outcome measure in different patient populations with varying knee injuries (of menisci, ACL or cartilage) [ 13, 14 ], knee OA [ 15, 16, 17, 18, 19] and total knee replacement [ 20 ]. The test-retest reliability was excellent, with intraclass correlation coefficients ranging from 0.91 to 0.99 for all subscales. validated in several different populations having surgical procedures due to knee complaints. 37 Full PDFs related to this paper. If the results are accurate according to the researcher's situation, explanation, and prediction, then the research is valid. What are the applications of the KOOS? The KOOS is intended to be used over short and long time intervals; to assess changes from week to week induced by treatment (medication, surgery, physical therapy) or over the years due to a primary knee injury, posttraumatic OA or primary OA (Roos and Lohmander 2003). Methods of estimating reliability and validity are usually split up into different types. Internal consistency or homogeneity was assessed using Cronbach’s alpha. Unfortunately, some concerns have been raised with regards to its validity and reliability. Reliability was measured by evaluating internal consistency (Cronbach α) and test-retest reliability (intraclass correlation coefficient). Currently, KOOS is available in 50 different languages and language variants [ 21 ]. and revealed acceptable reliability and validity. The KOOS questionnaire has demonstrated reliability, validity, and responsiveness among distinct populations exhibiting varying pathologies, injury durations, ages, and activity levels [ 5, 6, 8, 9, 19, 20, 21, 23, 34 ]. Test–retest reliability has been shown to be good, but higher among literate (r = 0.94, P < 0.001) than illiterate patients (r = 0.71, P < 0.001) before and after attending a rheumatology outpatient clinic . Since its inception, however, it has gained widespread popularity. J Orthop Sports Phys Ther. The properties of the KOOS in terms of reliability [Intraclass Correlation Coefficient (ICC)], internal consistency (Cronbach’s alpha), dimensionality (item–scale correlation) and construct validity (Spearman’s rank correlation) were evaluated. If … Construct validity was supported by the confirmation of the five predefined hypotheses involving expected correlations between KOOS-PS scale, KOOS subscales and SF-36 subscales. Furthermore, the Persian version of KOOS showed good validity, reliability, and internal consistency in patients with anterior cruciate ligament (ACL) injury. The test-retest reliability was assessed with the Kappa agreement correlation coefficient. Descriptive techniques were used to analyze and characterize the subjects. This study approved by the Ethics Committee of Tehran University of Medical Sciences (ethic number: … However, somewhat lower reliability was observed for the KOOS function in sport and recreation subscale (intraclass correlation coefficients of 0.45 and 0.65, respectively) and the other symptoms subscale (internal consistency, α = .56). TTCONCLUSION:The KOOS and KOOS-PS exhibit clinically acceptable psychometric properties. reliability, internal consistency, and discriminant validity of the F-KOOS among the community-dwellers with knee OA. Reliability of KOOS. The application of the KOOS-12 scale takes 2 minutes. The relationship between Knee Injury ans Osteoarthritis Outcome Score (KOOS) and Timed Up and Go test in patients with symptomatic knee osteoarthritis. Archives of Physical Medicine and Rehabilitation 86(2): 190-196. Cronbach α was 0.84 to 0.97 for all subscales, indicating adequate internal consistency. This revealed that the HK-KOOS had excellent content validity in the areas of relevance, representativeness, and understandability. Reliability of KOOS. The minimum detectable change (MDC90) was ±6 for OKS (±16 for the Pain Component Score (OKS-PCS) and ±15 for the Functional Component Score (OKS-FCS)). The KOOS questionnaire is a reliable and valid instrument to measure the condition of athletes undergoing ACL reconstruction. Results: Results for the IKDC, KOOS dimensions, and WOMAC dimensions, respectively, were as follows: Cronbach … The HK-KOOS was successfully cross-culturally adapted in HK, as shown by the satisfactory results of the reliability and validity tests. The 30SFW is the first PPM to evaluate short‐distance walking ability with evidence for both reliability and validity as well as minimum detectable change. translation process, followed by face validity and content validity.

Their strength is in large effect sizes to measure outcomes over time and their weakness is in weak-to-moderate reliability and weak construct validity in some subscales of the KOOS. Results: Results for the IKDC, KOOS dimensions, and WOMAC dimensions, respectively, were as … Internal consistency was assessed with the Cronbach’s alpha. The knee injury osteoarthritis score (KOOS) is an adult outcome measure used for assessing the patients' perspectives of their knee pain and disability. This tool was developed initially to use on adults. To evaluate the construct validity between SNQ and KOOS/ODI, Pearson correlation coefficient was computed. Multiple studies in patients with knee injury and knee OA report that the KOOS demonstrates expected convergent and divergent construct validity, with the KOOS more strongly correlated with subscales of the ShortForm- 36 (SF-36) that measure similar constructs (e.g., KOOS ADL with physical function, KOOS Sport/Rec with physical function, KOOS Pain with bodily pain), and less strongly with SF-36 … Confirmatory factor analysis confirmed the structural validity of OKS. It was hypothesised a priori that: (1) the correlations between the KOOS P and SF-36 BP subscale would be high; (2) the negative correlations "Assessing walking ability in subjects with spinal cord injury: validity and reliability of 3 walking tests." Validity. The KOOS and KOOS-PS exhibit clinically acceptable psychometric properties. Background The Knee injury and Osteoarthritis Outcome Score (KOOS) is a self-administered valid and reliable questionnaire for adults with joint injury or degenerative disease. The KOOS questionnaire can be used as a valid self-reported, disease-specific instrument in future studies on ACL-reconstructed athletes. A short summary of this paper. Reliability can be estimated by comparing different versions of the same measurement. Role of the funding source In the absence of a gold standard for pain, criterion validity … Comparative, validity and responsiveness of the HOOS-PS and KOOS-PS to the WOMAC physical function subscale in total joint replacement for osteoarthritis.
