Background and purpose A questionnaire was introduced by the New Zealand Arthroplasty Registry for use when evaluating the outcome of total ankle replacement surgery. We evaluated the reliability, validity, and responsiveness of the modified Swedish version of the questionnaire (SEFAS) in patients with osteoarthritis or inflammatory arthritis before and/or after their ankle was replaced or fused. Patients and methods The questionnaire was translated into Swedish and cross-culturally adapted according to a standardized procedure. It was sent to 135 patients with ankle arthritis who were scheduled for or had undergone surgery, together with the foot and ankle outcome score (FAOS), the short form 36 (SF-36) score, and the EuroQol (EQ-5D) score. Construct validity was evaluated with Spearman’s correlation coefficient when comparing SEFAS with FAOS, SF-36, and EQ-5D, content validity by calculating floor and ceiling effects, test-retest reliability with intraclass correlation coefficient (ICC), internal consistency with Cronbach’s alpha (n = 62), agreement by Bland-Altman plot, and responsiveness by effect size and standardized response mean (n = 37). Results For construct validity, we correlated SEFAS with the other scores and 70% or more of our predefined hypotheses concerning correlations could be confirmed. There were no floor or ceiling effects. ICC was 0.92 (CI 95%: 0.88–0.95), Cronbach’s alpha 0.96, effect size was 1.44, and the standardized response mean was 1.00. Interpretation SEFAS is a self-reported foot and ankle score with good validity, reliability and responsiveness, indicating that the score can be used to evaluate patients with osteoarthritis or inflammatory arthritis of the ankle and outcome of surgery. 相似文献

OBJECTIVE: To cross-culturally adapt and validate Singapore English and Chinese versions of the Lequesne Algofunctional Index of knee in patients with knee osteoarthritis (OA) in Singapore. METHODS: Singapore English and Chinese versions were cross-culturally adapted from the source English version following standard guideline (including cognitive debriefing). Patients were asked to complete an identical, pretested questionnaire containing the Lequesne index, Short Form 36 Health Survey (SF-36), and EQ-5D twice within 6 days. Reliability was assessed using Cronbach's alpha and intraclass correlation coefficients (ICC). Dimensionality was assessed by principal component factor analysis. Construct validity was tested by item-to-scale correlations and 12 and six a priori hypotheses for convergent and divergent construct validities, respectively. RESULTS: Singapore English and Chinese Lequesne indices were well accepted by patients in pilot testing and were therefore administered to a consecutive sample of 127 English- and 131 Chinese-speaking Singaporeans with knee OA. Acceptable internal consistency was observed for activities of daily living and the global index (alpha=0.72-0.82), and the good test-retest reliability for all scales in both versions (ICC=0.66-0.94). Expected item-to-scale correlations were presented only in activities of daily living in both versions. Factor analysis yielded two factors for both versions. Convergent and divergent construct validities were supported by the presence of hypothesized correlations between the Lequesne index and SF-36 and EQ-5D scales. CONCLUSION: Both versions of the Lequesne index demonstrated acceptable reliability and validity among multiethnic Asian patients with knee OA, which suggests that it could be used as a global index in the health-related quality of life (HRQoL) measurements in Singapore and possibly other Asian countries. 相似文献

OBJECTIVE: To assess the reliability, validity and responsiveness of the Australian/Canadian (AUSCAN) Osteoarthritis Hand Index in both Likert (LK) and Visual Analogue (VA)-scaled formats. METHODS: Two separate studies were conducted; the first addressing reliability and validity issues and the second addressing index responsiveness. In a group of 50 patients with osteoarthritis (OA) of the hand, test-retest reliability was assessed at a 1-week interval and internal consistency from single administrations of the Index. Construct validity was evaluated against several other outcome measures including the Functional Index for Hand Osteoarthritis (FIHOA), separate patient and physician global assessments, Doyle Index, grip strength, pinch grip, and Health Assessment Questionnaire. A 6-week washout retreatment design was used in a group of 44 OA hand patients to assess index responsiveness and comparative responsiveness against the FIHOA. RESULTS: Reliability and construct validity coefficients confirm the reliability and construct validity of both the AUSCAN LK3.0 and AUSCAN VA3.0 Indices. The washout retreatment study establishes index responsiveness and suggests that the AUSCAN LK3.0 and AUSCAN VA3.0 Indices may be more responsive than the FIHOA. CONCLUSIONS: The patient self-completed AUSCAN LK3.0 and AUSCAN VA3.0 Indices are reliable, valid and responsive and can be recommended as primary outcome measures for future hand OA clinical trials. 相似文献

BackgroundThe revised Foot Function Index (FFI-R) is a multidimensional instrument that was developed to assess a patient’s self-reported health-related foot function. The FFI-R is clinically useful and easy to apply, and it has comprehensive subscales assessing the pain, stiffness, psychosocial stress, disability, and activity limitations related to foot and ankle problems. The present study was conducted to validate the Turkish version of the FFI-R, and to demonstrate its use in a Turkish population with various foot and ankle problems. MethodsThe English version of the FFI-R was translated into Turkish, and then, it was administered to 124 patients (mean age of 39.9 years old) with foot and ankle problems and a mean symptom duration of 7.9 months. These patients completed two well-established foot and ankle-specific patient-reported outcome measures, the Foot and Ankle Outcome Score (FAOS) and the Manchester-Oxford Foot Questionnaire (MOX-FQ), and a general instrument, the 36-item Short Form Health Survey (SF-36). The test-retest reliability was evaluated using the intraclass correlation coefficient, and the internal consistency was measured using Cronbach’s alpha. The construct validity of the FFI-R was assessed by correlating its subscales with the FAOS, MOX-FQ, and SF-36 subscales. ResultsThe test-retest reliability of the FFI-R ranged between 0.84 and 0.97. The internal consistency was 0.97 for the overall FFI-R, and it ranged between 0.85 and 0.97 for the subscales. Significant correlations were obtained between the FFI-R subscales and the FAOS, MOX-FQ, and SF-36 subscales. ConclusionsThe Turkish version of the FFI-R was found to be a reliable and valid instrument for measuring the foot and ankle-related functional disability and health status of Turkish patients with foot and ankle problems. 相似文献

OBJECTIVES: To assess the test-retest reliability and the construct validity of a modified version of the Lequesne index. METHODS: Patients with symptomatic knee osteoarthritis (OA) fulfilling the revised criteria of the American College of Rheumatology completed the Lequesne index twice at a 3-h interval. Impairment outcome measures and patients' perceived discomfort in walking and handicap were recorded. An item-by-item analysis was performed. Items having insufficient psychometric properties were excluded. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC) and the Bland and Altman method. Construct validity was investigated using Spearman rank correlation coefficient and a factor analysis was performed. RESULTS: Eighty-eight patients were included. One question assessing pain (question IE) had a weak reliability (Kappa (kappa) = 0.39) and was excluded. The test-retest reliability of the modified questionnaire was excellent (ICC = 0.95). Expected convergent and divergent correlations were achieved except for visual analog scale pain (VAS P) and VAS handicap (VAS H) (0.46 and 0.40, respectively), and the "a priori" double stratification was confirmed by factor analysis, explaining 48.7% of the variance. CONCLUSION: The modified form of the Lequesne index has sufficient psychometric properties to be used to assess pain and function in knee OA in a French population. 相似文献

BackgroundThe aim of this study was to evaluate the reliability and validity of an adapted Turkish version of the Scoliosis Japanese Questionnaire- 27 (SJ- 27). MethodsTranslation and retranslation of the English version of the SJ- 27 was conducted, and all steps of the cross-cultural adaptation process were performed. The Turkish version of the SJ- 27, the Scoliosis Research Society-22 (SRS- 22) questionnaire and the Short Form-36 (SF- 36) were performed to 139 patients with AIS. Reliability was assessed using the test–retest method (Pearson's correlation coefficient); internal consistency was analyzed using Cronbach's alpha. Validity was assessed by correlating the SJ- 27 with the SRS- 22 questionnaire and SF- 36. ResultsThe mean Cobb angles were 23.2 ± 8.3° and 19 ± 5.9° for thoracic and lumbar regions, respectively. The SJ- 27 showed excellent test/retest reliability with an Intraclass correlation coefficient of 0.99. Internal consistency of the SJ- 27 was found to be very good (Cronbach's alpha = 0.991). The SJ- 27 demonstrated very good construct validity with the SRS- 22 total score (r = 0.61). The similar domains of the SJ- 27 and SF- 36 questionnaire was correlated also in the study. ConclusionsThe Turkish version of the SJ- 27 to measure health related quality of life in adolescent idiopathic scoliosis was found to have very good validity, excellent reliability, and high internal consistency. 相似文献

BackgroundThe Shoulder Pain and Disability Index (SPADI) is a simple disease specific questionnaire that is used to evaluate the impact of shoulder disorders. The purpose of this study was to translate the SPADI into Japanese (SPADI-Jp) and evaluate its reliability and validity in Japanese patients with shoulder disorders. MethodsCross-cultural adaptation of the SPADI was performed according to international guidelines. A total of 100 patients with shoulder disorders participated in this study. Each participant was asked to finish the SPADI-Jp, Disability of Arm, Shoulder and Hand (DASH), and the Short-Form 36 (SF-36) at the initial visit. Thirty-four patients repeated the SPADI-Jp to assess the test–retest reliability. The test–retest reliability was quantified using the interclass correlation coefficient (ICC), while Cronbach's alpha was calculated to assess the internal consistency. The construct validity was assessed using Spearman's rank correlation coefficients. ResultsInternal consistency in the SPADI-Jp was very high (0.969), as measured by the Cronbach's alpha. The ICC of the SPADI-Jp was 0.930. There was a strong, positive correlation between the DASH and the SPADI-Jp (r = 0.837, p < 0.001). The SPADI-Jp was significantly correlated with most of the SF-36 subscales. The correlations of the SPADI-Jp with physical subscales of the SF-36 were stronger than those with the other subscales. ConclusionsWe demonstrated that the SPADI-Jp is a reliable and valid self-assessment tool. Because cross-cultural adaptation, validation, and reliability of the disease-specific questionnaire for shoulder pain and disability have not been evaluated in Japan, the SPADI-Jp can be useful for evaluating such patients in the Japanese population. 相似文献

BackgroundQuality of life (QOL) measures can be used to make sound clinical decisions after reconstruction of the anterior cruciate ligament (ACL). The purpose of the present study was to translate and cross-culturally adapt the Anterior Cruciate Ligament Quality of Life (ACL-QOL) questionnaire into the Persian language and to evaluate its psychometric properties. MethodsThe process of translation and cross-cultural adaptation followed the World Health Organization method. One hundred and forty-five patients with ACL reconstruction (ACL-R) filled out the Persian versions of ACL-QOL and the SF-36 Questionnaire. The measurement properties of internal consistency, agreement, criterion validity, floor and ceiling effects were measured. 40 out of 145 patients with ACL-R completed the Persian version of the ACL-QOL questionnaire twice for the test-retest reliability. ResultsThe questionnaire had high internal consistency (Cronbach's α = 0.96). The intraclass correlation was excellent for reliability and agreement in five domains and overall score (ICC 0.87, 0.74, 0.90, 0.85, 0.81 and 0.89; p < 0.001). The standard error of measurement and the minimum detectable change were found to be 3.28 points and 9.9 points, respectively. There was a strong correlation between each item and the total score of the Persian version of ACL-QOL questionnaire. The questionnaire showed strong and moderate criterion validity ( r = 0.61, r = 0.37) with SF-36 physical component score and mental component score, respectively. No ceiling and floor effects were observed. ConclusionsPersian version of the ACL-QOL questionnaire has acceptable reliability and validity and can be used in assessing Iranians quality of life after ACL reconstruction. 相似文献

OBJECTIVE: To validate a translated and culturally adapted version of the Arthritis Impact Measurement Scale (AIMS) 2 in primary care patients with osteoarthritis (OA) of the hip and knee. METHOD: The AIMS2 was translated into German and culturally adapted. The questionnaire then was administered to 220 primary care patients with OA of the knee or hip. Two hundred and nine questionnaires were returned and analysed. Test-retest reliability was tested in 50 randomly selected patients, of those 42 completed the questionnaire after 2 weeks for a second time. RESULTS: Item-scale correlations were reasonably good as well as the discriminative power of separate scales. The assessment of internal consistency reliability also revealed satisfactory values; Cronbach's alpha was 0.77 or higher for all scales. The test-retest reliability, estimated in an intraclass correlation coefficient (ICC), exceeded 0.90, except the "social activities" scale (0.87). Since only patients with OA of the lower limb were enrolled, substantial floor effects occurred in the "arm function" (28.2%) and the "hand and finger function" scale (29.2%). The principal factor analysis confirmed the postulated three-factor structure with a physical, physiological and social dimension, explaining 48.5%, 13.9% and 6.8% of the variation, respectively. External validity was assessed by calculating correlations to the Western Ontario and MacMaster (WOMAC) osteoarthritis questionnaire a pain visual analogue scale (VAS) and the Kellgren score as well as to disease duration. Spearman's "R" achieved satisfactory values for the corresponding WOMAC scales and the pain-VAS. Correlations with disease duration as well as with the radiological grading were low. CONCLUSION: The GERMAN-AIMS2 is a reliable and valid instrument to assess the quality of life (QoL) in primary care patients suffering from OA. 相似文献

OBJECTIVE: To evaluate the acceptability, reliability, validity and responsiveness of the Turkish version of Western Ontario and McMaster Universities (WOMAC) osteoarthritis (OA) index in physiotherapy outpatient practice in Turkey. METHOD: Data were obtained from 72 patients with OA of the knee. They were asked to answer two disease-specific questionnaires (WOMAC LK 3.1 and Lequesne-Algofunctional Index of Severity for the knee) and one generic instrument (Medical Outcomes study SF-36 Survey-SF-36). Acceptability was assessed in terms of refusal rate, rates of missing responses, and administration time. Reliability was assessed using Cronbach's alpha. Content validity was assessed by examining the floor and ceiling effects, and skew of the distributions. Convergent and divergent validity was assessed by examining the Pearson's correlation coefficients. Responsiveness was determined by examining effect size (ES), standardized response means (SRM) and P values generated using Wilcoxon's test. RESULTS: The overall response rate was 100%. Alpha values for all WOMAC subscales exceeded the value of 0.70 at both baseline and follow-up assessments. Frequency distributions of scores were symmetrical. Subscales had negligible floor and ceiling effects. Both pain and physical function subscales were fairly correlated with the subscales measuring similar constructs of SF-36, whereas they were weakly correlated with other dimensions of SF-36. A good correlation was obtained between WOMAC total and Lequesne index. The pain and physical function subscales of WOMAC index were the most responsive subscales. CONCLUSION: The Turkish WOMAC OA index is acceptable, valid, reliable and responsive for use in Turkish patients with knee OA. 相似文献

ObjectiveTo evaluate the test-retest reliability and construct validity of the concussion knowledge assessment tool (CKAT) as a measure of knowledge of concussion and its management among chiropractic subgroups and to compare these properties for two scoring strategies for the CKAT. MethodsThree chiropractic subgroups (first year students, interns and sports chiropractors) completed the CKAT via SurveyMonkey with as second administration two to six weeks later for a subset of respondents. Scatter plots and Intraclass Correlation Coefficients (ICC) were used for test-retest reliability. A priori hypotheses regarding the relationship of CKAT scores across known subgroups, and with concussion knowledge self-rankings were established prior to data collection. Distributions of CKAT scores were compared across the subgroups using boxplots and ANOVA for known groups validity, and correlation of CKAT scores with concussion knowledge self-ranking was examined. ResultsTest-retest ICC for the revised scoring was 0.68 (95%CI 0.51–0.80). First year students had a mean revised CKAT (out of 49) of 36.9 (SD= 4.7), interns 39.9 (SD=3.0) and sports chiropractors 41.8 (SD=3.2) which are significantly different (F 2,125=17.54; p<0.0001). ConclusionsThe CKAT distinguished between chiropractic subgroups expected to have different levels of knowledge, supporting construct validity, however, it did not achieve adequate test-retest reliability. 相似文献

BackgroundA variety of outcome measures are available to evaluate physical impairment and disability in patients with knee osteoarthritis, and most physician-rated measures are not validated. The objective of this study was to assess the validity and reliability of an observer-based knee scoring system of the Japanese Orthopaedic Association (the JOA) commonly used in Japanese clinical practice, and to determine demographic variables affecting the score. MethodsA consecutive series of 85 patients with primary knee osteoarthritis completed the JOA (four domains pain on walking, pain on ascending or descending stairs, range of motion, and joint effusion), two validated patient-rated measures including the generic instrument of the Medical Outcomes Study 36-Item Short-Form (the SF-36) Health Survey, and the disease-specific scale of the Japanese Knee Osteoarthritis Measure (the JKOM), and a performance based timed-up-and-go test (TUG). Concurrent validity was determined by examining correlations of the JOA with the SF-36 and the JKOM. Construct validity was verified by correlating each domain of the JOA with objective measurements of TUG using Spearman’s rank correlation coefficient. Intra- and interobserver reliability and internal consistency of the JOA were evaluated with another cohort of 32 patients who had a knee disorder at baseline and again at a mean of 18 days later. ResultsThe JOA was significantly correlated with validated patient-rated outcome measures (the JKOM, the SF-36), indicating concurrent validity of the JOA. Domains of the JOA had significant correlations with the TUG, showing adequate construct validity. Intra- and interobserver reliability for the JOA showed a moderate to almost perfect agreement, and internal consistency of Cronbach’s α indicated that the JOA score was a highly reliable instrument to assess knee osteoarthritis. As a demographic variable, age was highly correlated with the JOA. ConclusionsThe JOA, generally used as an observer-derived knee scoring system, is a valid and reliable tool for evaluating functional status in patients with knee osteoarthritis. 相似文献

BackgroundTo provide a cross-cultural French adaptation of the Achille’s Tendon Total Rupture Score (ATRS) and to assess its psychometric performances. MethodThe ATRS questionnaire was first translated and inter-culturally adapted into French according to international guidelines. Then, 95 subjects were recruited to complete the French version of the ATRS twice (2 weeks of interval). The SF-36 and VISA-A were used as comparative questionnaires. The psychometric properties of the questionnaire were evaluated (test-retest reliability, internal consistency, construct validity, floor/ceiling effects). ResultsThetest-retest reliability was excellent (ICC of 0,966 (95% CI:0.644–0.879)) and the internal consistency very high (Cronbach’s alpha of 0,98). The convergent and divergent construct validity were also confirmed. Finally, none of the subjects obtained the lowest score (0) or the maximal score (100) to the questionnaire. ConclusionA valid and reliable French version of the ATRS is now available. 相似文献

DesignCross-sectional clinical measurements. IntroductionActivity limitation is often persistent after surgically treated carpometacarpal (CMC) joint osteoarthritis (OA). PurposeTo describe content and concurrent validity, test–retest reliability and internal consistency of the Swedish version of the Patient Specific Functional Scale (PSFS) in patients with surgically treated CMC joint OA. MethodsFifty-eight patients were assessed ten weeks after surgical treatment of CMC joint OA. PSFS, the shorter version of Disabilities of the Arm, Shoulder and Hand (Quick DASH), EuroQol-5Dimensions (EQ-5D), pain intensity, joint movement of CMC joint, grip and pinch strength were assessed. Classification of activities was done according to the International Classification of Functioning, Disability and Health (ICF). Spearman correlation, intra-class correlation coefficient (ICC) and Kappa were calculated to assess validity, test–retest reliability and internal consistency. The PSFS was administered twice, 2–3 days apart. ResultsAll of the activity limitations stated in the PSFS could be classified according to the activity component in the ICF. Significant correlations for the PSFS were obtained with pain at rest ( rs = ?0.36) and the Quick DASH ( rs = ?0.28). Test–retest reliability was good, ICC (0.79) and the three items of the PSFS correlated 0.69–0.83 with the total score of PSFS. ConclusionContent validity was excellent, concurrent validity was low-moderate, as in earlier studies. The PSFS could be a valuable supplement to existing measures in measuring activity limitations in individuals with surgically treated CMC joint OA. Level of evidenceNot applicable. 相似文献

BackgroundWith the increasing number of patients with knee osteoarthritis undergoing TKAs in China, there is a clear need for a valid, short, joint-specific patient-reported outcome measure such as the Oxford Knee Score (OKS). Questions/purposesTo test the translated and cross-culturally adapted Chinese (Mandarin) version of the Oxford Knee Score (OKS-CV) and its (1) reliability, (2) construct validity, (3) dimensionality, and (4) responsiveness. MethodsThree native Chinese bilingual translators (a professional English translator, an experienced orthopaedic surgeon, an advanced-practice nursing specialist) translated the English-language OKS into Mandarin Chinese. A consensus panel created a synthesis of those efforts, which then was back-translated by two bilingual nonmedical, professional English-language translators. The OKS-CV was developed according to the guidelines of copyright holders. Between March 2013 and March 2015, 253 patients underwent TKAs. Among them, 114 Mandarin-speaking patients with knee osteoarthritis underwent primary unilateral TKA (age, 67 ± 7 years; range, 55–84 years; female, 80%; preoperatively 54% had moderate to severe knee osteoarthritis), completed the preoperative questionnaires, and were followed up, with a mean postoperative followup of 2.7 years (SD, 0.5 years). Eligibility criteria were (1) patients with knee osteoarthritis who were scheduled to have a primary unilateral TKA, (2) patients who were fluent in Mandarin, and (3) consent to participate. The exclusion criteria were: (1) lack of understanding of Mandarin, and (2) inability to comprehend the questionnaires owing to cognitive impairment. To evaluate test-retest reliability, another group of 35 Mandarin-speaking outpatients with knee osteoarthritis (age, 61 ± 10 years; range, 44–84 years; female, 77%) was recruited to complete the OKS-CV twice at a 1-week interval. Reliability was tested using Cronbach’s alpha and intraclass correlation coefficient (ICC). Construct validity was evaluated using Spearman’s rank correlation coefficient to quantify the correlations between the OKS-CV and the WOMAC, Short Form-8 Health Survey (SF-8TM), and EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D). Exploratory factor analysis was performed to clarify dimensionality. The eigenvalue indicates the importance of each factor obtained from factor analysis. Responsiveness was determined by standardized response mean (SRM) and effect size (ES) from preoperative and postoperative scores of the OKS-CV. Floor and ceiling effects also were analyzed. ResultsThe internal consistency (Cronbach’s alpha = 0.89) and test-retest reliability (ICC = 0.93; 95% CI, 0.87–0.97) proved good. Convergent construct validity was supported by moderate to strong correlations between the OKS-CV and the WOMAC (r = −0.80, p < 0.001), the SF-8TM physical component summary (r = 0.65, p < 0.001), and the EQ-5D usual activities (r = −0.41, p < 0.001) and mobility (r = −0.35, p < 0.001). There also were correlations between the OKS-CV and the SF-8TM mental component summary (r = 0.58, p < 0.001) and the EQ-5D anxiety/depression (r = −0.35, p < 0.001). The factor analysis yielded three factors with eigenvalues greater than 1. Responsiveness was excellent (SRM = 1.52; ES = 1.52). No floor or ceiling effect was observed. ConclusionsThe OKS-CV showed good acceptability and psychometric properties for the intended population. Future studies are needed to evaluate the mental state of patients with knee osteoarthritis. Clinical RelevanceThe OKS-CV appears to be a reliable, valid, and responsive instrument for Chinese patients with knee osteoarthritis. Based on these results we believe the OKS-CV can be used as a valuable tool for the assessment of patient-reported outcomes in Chinese patients with knee osteoarthritis before and after TKA. 相似文献

We assessed whether a disease-specific, self-administered questionnaire could replace a generic instrument as an outcome tool after total hip replacement, and tested the validity and reliability of the Swedish WOMAC osteoarthritis index. 58 patients operated on with total hip arthroplasty 2-10 years ago were randomized to the study. All patients were asked to answer one disease-specific questionnaire (WOMAC osteoarthritis index) and two generic instruments (NHP and SF-36) in the same week. The procedure was repeated after 4 weeks. We tested content validity, construct validity, criterion validity, test-retest reliability and internal consistency reliability according to total score, domains and items. We found that both the generic instruments (NHP and SF-36) and the disease-specific test (WOMAC) had a high validity, i.e., measuring what they were supposed to measure (high validity). The questionnaires were also reproducible over time (high reliability). We suggest the Swedish WOMAC to be used after total hip arthroplasty in future studies. 相似文献

IntroductionFoot problems are one of the main causes of seeing a doctor. According to the World Health Organization's definition of health, the healthcare system must consider patients’ quality of life as an important entity. In this regard, many tools have been developed to evaluate patients' opinions about their health status. The purpose of the present study is to evaluate the validity and reliability of the Persian version of the Foot Self-Assessment Questionnaire (SAFE-Q) in patients with foot orthopedic problems. Method215 people aged 17–60 years with orthopedic foot problems were included in this cross-sectional study. The Spearman correlation coefficient of SAFE-Q questionnaires versus Foot Function Index (FFI) questionnaire was evaluated for the convergent validity. Forty-three people randomly completed SAFE-Q again one week later. Intraclass correlation coefficient (ICC) and Cronbach’s alpha was calculated to evaluate the test-retest reliability and internal consistency of the SAFE-Q, respectively. ResultsA strong relationship was found between the SAFE-Q total score and other scales with FFI questionnaire (r = 0.52 to 0.87). ICC test-retest reliability and Cronbach’s alpha were 0.981 and 0.98 for SAFE-Q, respectively. ConclusionThe results indicate that the Persian version of the SAFE-Q questionnaire has acceptable validity and reliability and can be used to assess the health status and quality of life of Persian speakers with orthopedic foot problems. 相似文献
