Lower Extremity Functional Scale

Purpose. The purpose of this study was to cross-culturally adapt and validate the Simplified Chinese version of the Lower Extremity Functional Scale (SC-LEFS). Methods. The original English version of the Lower Extremity Functional Scale was translated and cross-culturally adapted into Simplified Chinese according to international guidelines. The SC-LEFS and 36-Item Short-Form Health Survey were administered to 213 patients with lower extremity musculoskeletal disorders. Psychometric properties including internal consistency, test-retest reliability, content validity, and construct validity were tested. Results. There were no floor or ceiling effects for the SC-LEFS. The scale had high values for internal consistency (Cronbach α=0.97) and test-retest reliability (intraclass correlation coefficient=0.97). Corrected item-total correlations for every item ranged from 0.67 to 0.89. And the item-level content validity index (I-CVI) for each item ranged from 0.78 to 1.00. Principal component analysis revealed a one-factor structure. Nine of ten prior hypotheses were confirmed, which further supports good construct validity within the SC-LEFS. Conclusion. The SC-LEFS has high internal consistency, good test-retest reliability and content validity, convergent construct validity, and a one-factor structure. Thus, it could be regarded as a reliable and valid tool to assess activity limitations in Chinese patients with lower extremity musculoskeletal disorders.

Lower Extremity Functional Scale

Two very common scales used in the assessment of patellofemoral pain syndrome are the anterior knee pain scale and the lower extremity functional scale. There is only limited evidence regarding how specifically reliable and meaningful these scales are when assessing the syndrome.The purpose of this study was to assess which questions in both scales are suitable for patellofemoral pain syndrome patients.20 patients with patellofemoralpain were recruited from the physiotherapy waiting list of the local hospital and asked to complete the anterior kneepain scale and the lower extremity functional scale on two occasions at least one week apart. A general test-retest reliability of the scales was measured in addition withtest-retest and internal consistency of each single question. Finally,the questions markedas ‘no problem’ in both sessions were also measured. The total scores of the two scales were found to be highly reliable. However, the anterior knee pain scale revealed five questions with moderate test retest reliability, two questions with less internal consistency whilst it included three less meaningful questions. The lower extremity functional scale showed four questions with moderate test retest reliability,one question with less internal consistency andsix meaningless questions. This study agrees with previous research stating that there are questions in both scales that can be considered meaninglessand less reliable and should probably be excluded or replaced with other questions. The study provides useful information for the development of a more appropriate patellofemoralpain syndrome scale or a modified anterior knee pain scale and lower extremity functional scale for patellofemoralpain syndrome use only.

The current study was planned to test the validity and reliability of the Turkish version of the COVID-19 Literacy Scale. The sample of the study was taken from 473 individuals. In this study, language validity, content validity and construct validity were examined to determine the validity of the scale. Its reliability was evaluated by internal consistency, split-half reliability, and test-retest reliability method. It was defined that the scale has a two-factor structure as a result of EFA and its factor loadings are in the appropriate range (0.852–0.324). According to the CFA result, it was determined that the model-data fit was at a good level. The Cronbach values for the whole scale and subscales were .92, .90, and .87, respectively. It was observed that the test-retest value was .95. It was concluded that the Turkish form of the COVID-19 Literacy Scale is a reliable and valid tool.

Introduction. The Michigan Hand Outcomes Questionnaire (MHQ) is a patient-rated hand outcome instrument. It is widely used in orthopedic and neurological conditions of the hands and upper limbs. To gain more knowledge on hand outcomes from a Thai patient perspective, an MHQ-Thai version is required. Purpose of the Study. The study is aimed at translating and cross-culturally adapting the MHQ into Thai and at examining the validity and reliability of the translated version. Methods. The Beaton protocol for cross-cultural adaptation of self-reported measures was used in the translation process. Three occupational therapists were asked to assess content validity while 30 participants were asked to fill in the questionnaire in order to assess construct validity, internal consistency, and test-retest reliability. Results. All six domains of the MHQ were translated into Thai without any major problems. However, items related to the characteristics of the patients were adapted to suit the Thai context. The MHQ-Thai version had good content validity (IOC 0.972). The construct validity revealed a low-to-high correlation between every subscale of the MHQ-Thai version. The intraclass correlation coefficient (ICC) of the test-retest reliability for the six domains ranged from 0.788 to 0.956, with excellent correlation (ICC = 0.953) for the total score. Cronbach’s alpha was 0.835 for the total score of the MHQ-Thai version, indicating good internal consistency. Discussion and Conclusions. MHQ was successfully cross-culturally adapted into Thai. The MHQ-Thai version is a valid and reliable instrument for evaluating the self-perception of Thai people who have hand and upper limb injuries.

AbstractObjectiveThe present study aimed to translate the English version of the Nutritional Form For the Elderly into Simplified Chinese, as well as to test the reliability (homogeneity and stability) and validity (content and construct validity) of the Chinese version of the Nutritional Form For the Elderly (NUFFE-CHI).DesignThe study adopted a cross-sectional design. The English version of the NUFFE was translated into Simplified Chinese and a questionnaire survey was conducted. The data were analysed with statistical methods to estimate the homogeneity, stability, content and construct validity.SettingJinzhou City, China.SubjectsA total number of 701 community-dwelling older adults answered the questionnaire, including background variables and the NUFFE-CHI. A small group of the participants (n 50) completed the NUFFE-CHI twice for test–retest reliability.ResultsCronbach’s α was 0·65 and the split-half reliability was 0·67. Item-to-total correlation analyses showed that the scale has sufficient internal consistency. The test–retest reliability regarding the total scores of NUFFE-CHI was reflected in an intra-class correlation coefficient of 0·88. The intra-class correlation coefficients between the test and retest of the NUFFE-CHI items varied between 0·43 and 0·98. A content validity index of 0·83 explained good content validity. Construct validity was demonstrated in an exploratory factor analysis with a six-factor solution, explaining 57·65 % of the variance.ConclusionsThis first testing of the NUFFE-CHI indicates sufficient evidence for reliability, content and construct validity. Further testing studies regarding homogeneity, concurrent validity, sensitivity and specificity are required before the NUFFE-CHI can be used as a screening instrument in clinical settings and in research.

Abstract Background Suicidal ideation is a key precursor for suicide attempts and suicide deaths. Performing routine screening of suicide precursors can help identify people who are at high risk of death by suicide. This is, arguably, an important suicide prevention effort. The aim of this study was to assess the validity, reliability, and factor structure of the Suicidal Ideation Attributes Scale (SIDAS) in a three-month longitudinal study with people with a diagnosis of schizophrenia or non-affective psychosis and experiences of suicidal ideation and/or behaviours. It was predicted that the SIDAS would have high internal consistency, test-retest reliability, convergent, discriminant and construct validity. Methods Ninety-nine participants experiencing psychosis completed the SIDAS at baseline and 89 participants completed it 3 months later. Additionally, participants completed a demographic questionnaire, the Beck Scale for Suicide Ideation, the Beck Hopelessness Scale, and the Defeat and Entrapment Scales. The internal consistency, test-retest reliability, convergent validity, and discriminant validity of the SIDAS were investigated in comparison to other constructs. Factor analysis was performed to examine the factor structure of the scale. Results Principal component analysis yielded a theoretically coherent one-dimensional factor structure of SIDAS, suggesting good construct validity (PCA = .71). The SIDAS had high internal consistency (α = .89) and good test-retest reliability (α = .73). It was highly correlated with other self-report measures, including the Beck Scale for Suicide Ideation, Beck Hopelessness Scale, Defeat and Entrapment scales, indicating excellent construct validity. Conclusion The SIDAS is a valid and reliable self-report instrument for assessing the severity of suicidal ideation in a population of people with a diagnosis of schizophrenia or non-affective psychosis. Further research should test the psychometric properties of the scale in individuals experiencing different mental health problems in cross-cultural settings, in order to establish its broader validity, reliability, and clinical utility.

BACKGROUND: In order to administer the International Knee Documentation Committee Subjective Knee Form (IKDC) questionnaire to Arabic speakers, a rigorous process of cross-cultural adaptation and validation is required in order to reach equivalence between the original publication and target version of the questionnaire. OBJECTIVES: The main aim of this study is to translate and culturally adapt the IKDC into Arabic to suit the Arabic population. The secondary aim is to assess the Arabic version of the IKDC in order to test the psychometric characteristics (reliability, validity and dimensionality). METHODS: The translation process has been carried out according to cross-cultural adaptation guidelines in accordance with the American Orthopaedic Society for Sports Medicine guidelines with forward/backward translations and pre-testing. The Arabic IKDC, Knee injury and Osteoarthritis Outcome Score (KOOS), RAND-36-Item Health Survey (RAND-36) questionnaire, and visual analogue scales (VAS) of pain were tested in 105 ACLR patients. Test-retest reliability, internal consistency, construct validity and content validity were evaluated. RESULTS: The test-retest reliability proved excellent with a high value for the intraclass correlation coefficient (r= 0.95). The internal consistency was strong (Cronbach’s α= 0.91). Good construct validity by the strong correlations between similar component of the KOOS subscales, Rand-36 subscales and VAS, and good content validity with absence of floor and ceiling effects. CONCLUSIONS: The Arabic version of the IKDC is a valid and reliable instrument for Arabic patients with ACLR. However, further research is required with a more varied knee sample in order to enable generalisation to a wider population.

Abstract Background We provide a meta-analysis for clinicians and researchers regarding the psychometric properties of the WOMET as a patient-reported outcome measure (PROM) for patients with meniscal pathologies. Methods A comprehensive literature search identified 6 eligible papers evaluating WOMET measurement properties in patients with different meniscal injuries and meniscal treatments following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The quality of the included studies was evaluated using the four-point Consensus-based Standard for the selection of health Measurement Instruments (COSMIN) Checklist for good measurement properties. The checklist was specifically developed for studies on health-related PROMs. Results Our meta-analysis suggests that the WOMET can be used to evaluate patients with different meniscal injuries and meniscal treatments, especially acute or chronic meniscal injuries and traumatic or degenerative meniscal injuries treated operatively or conservatively. The WOMET shows satisfactory internal consistency, test-retest reliability, and construct validity. Due to limitations in both sample sizes and methodologies of the included studies, no conclusions can be drawn regarding the WOMET’s content validity, structure validity, cross-cultural validity, measurement error, or responsiveness. A further limitation of the studies included in this meta-analysis is the lack of cross-cultural validation, although recommended by the COSMIN Standards. Conclusions The first meta-analysis on measurement properties of the WOMET demonstrates satisfactory internal consistency, test-retest reliability, and construct validity. Further studies are needed, focusing on the methodological deficiencies highlighted in this meta-analysis. To ensure that the WOMET adequately reflects the symptoms, functions, and quality of life of patients with meniscal tears based on COSMIN criteria, it is necessary to assess the structural validity and content validity of this PROM.

Introduction: This study examines the validity and the reliability of the translated-into-Italian version of the SCNS-SF34 melanoma module (SCNS-M12-Ita) for a sample of patients with melanoma ( n = 268). Methods: Content validity was analyzed by examining the redundancy of items. Floor/ceiling effects were investigated via frequency tables. Factor structure was studied through principal component analysis. Internal consistency was evaluated with Cronbach α. Test–retest reliability was analyzed using intraclass correlation coefficients (ICCs). Convergent–discriminant validity was studied by calculating Pearson correlations. Construct validity was investigated by comparing subgroups of patients through multivariate analysis of variance. Results: Content validity of the SCNS-M12-Ita was satisfactory. The floor effect ranged from 24.3% to 82.5%. The 2-factor solution explained 61.4% of the total variance. Internal consistency was excellent for component 1 (α = 0.92) and questionable (α = 0.58) for component 2. Test–retest reliability was excellent for component 1 (ICC = 0.92) and poor for component 2 (ICC = 0.58). Except for component 2, item-total correlations were greater than 0.60. Construct validity was confirmed, as the expected correlations ( r < 0.40) were observed and 60% of the postulated hypotheses about between-group differences were confirmed. Conclusions: The study demonstrated that the SCNS-M12-Ita is a valid and reliable instrument for assessing the supportive care needs of patients with melanoma.

Background/Aims Lower extremity functional scales in Turkish are limited in number and generalisability. The aims of this study were to translate the Lower Extremity Functional Scale into Turkish, and to investigate its reliability and validity in patients with different musculoskeletal conditions in their lower extremities. Methods The Turkish Lower Extremity Functional Scale, Visual Analogue Scale and Timed Up and Go test were administered in 256 outpatients with a re-test after 24–48 hours. Internal consistency, test–retest reliability, construct validity, factor structure and floor-ceiling effects were investigated. Findings The Scale has good reliability and validity. The Spearman correlation coefficient was 0.91 and intraclass correlation coefficient was 0.923. The standard error of measurement value was 4.015 and internal consistency coefficient was 0.92. Item-total correlation values were 0.46–0.74. It had a 3-factor structure, explaining 58.51% of the total variance and the eigenvalues were 1.04–8.26. It had no floor and ceiling effects, and was negatively correlated with the Visual Analogue Scale and Timed Up and Go test (P=0.000). Conclusions The Turkish Lower Extremity Functional Scale is a reliable and valid tool to be used in participants with lower extremity musculoskeletal dysfunctions. Evaluation of its responsiveness and minimal clinically important difference in future studies would have a great value.

Background: The Copenhagen Burnout Inventory (CBI) is a commonly used tool for evaluation of job burnout in three (personal, work-related and client-related) domains. The aims of this study were to translate and investigate the psychometric properties of the Iranian (Persian) CBI. Methods: A total of 750 employees of different occupations (from educational centres, healthcare, industrial settings, and social services) participated in this descriptive methodological study. Aforward-backward procedure was applied and content validity was evaluated by a panel of10 experts. Exploratory and confirmatory factor analyses were used for construct validity. The internal consistency (using Cronbach’s alpha), test-retest reliability (using intraclass correlation coefficient – ICC), and feasibility (using ceiling and floor effect) were also assessed for this tool. Results: Content validity of the Persian CBI was established. Three-factor structure of the PersianCBI was supported by the factor analysis, and this confirmed the construct validity of the instrument. The internal consistency (Cronbach’s alpha ranged from 0.82 to 0.90) and test-retest reliability (ICC ranged from 0.85 to 0.95) were excellent and there was no ceiling or floor effect. Conclusion: The Persian CBI is a valid and reliable measurement tool for burnout in the Iranian context.
