Psychometric Evaluation of the Taiwanese Version of the Western Ontario Rotator Cuff Index

Abstract Background: The Western Ontario Rotator Cuff (WORC) index is a self-report questionnaire that measures the disease-specific quality of life in patients with rotator cuff injuries. The aim of this study was to evaluate the psychometric properties of the Taiwanese version of WORC (T-WORC) in patients with rotator cuff tear (RCT) before surgery. Methods: A cross-sectional study design was used. The study was composed of two phases: translation of the WORC into Taiwanese version of WORC, and 210 patients with rotator cuff tear before surgery completed the questionnaire twice within 2 weeks. The main outcome measures included reliability and validity. Reliability was assessed with internal consistency and test-retest. Internal consistency was assessed using the Cronbach’s alpha and test-retest reliability was assessed using the intraclass correlation coefficient (ICC). Construct validity was evaluated by examining convergent, divergent, known-group validity, and exploratory factor analysis (EFA). Results: The T-WORC demonstrated satisfactory reliability with the Cronbach's alpha of .94, and ICC (2 week-interval) of .79. The convergent validity showed that the T-WORC was significantly positively correlated with the disability of the arm, shoulder, and hand and numerical rating scales of pain, but negatively correlated with the Short Form-12. The divergent validity was shown by the low correlation between T-WORC and state anger scale. The known-group validity showed a significant difference between the high pain group and the low pain group. The EFA revealed 4 factors, daily activities and function, physical symptoms, emotion, and shoulder clicking and recreation, which explained 66.13 % of the variance. Conclusions: The findings of this study did not support the 5-domain structure proposed by the original version. Nevertheless, the T-WORC still demonstrated adequate psychometric properties and could be a useful instrument for assessing the RCT patients' quality of life before surgery.

Background: The Western Ontario Rotator Cuff Index (WORC) is an assessment tool developed to evaluate quality of life in patients with rotator cuff disease (RCD). The purpose of this study is to translate the WORC index into Spanish and to evaluate its reproducibility and internal consistency in patients with RCD. Methods: Following guidelines from literature, the WORC index was translated. Sixty patients with RCD were asked to complete the questionnaire. To evaluate reliability, they were asked to answer it for a second time within the next 14 days. The Cronbach’s α (CA) and the intraclass correlation coefficient (ICC) were calculated to determine test-retest reliability and internal consistency. Bland-Altman plot and reliable change index (RCI) were used to evaluate measurement error. Results: Cronbach’s α was 0.96 for the total WORC score (ranges 0.85-0.94 for the five domains).Excellent test-retest reliability was seen with an ICC of 0.98, with the domains ranging between 0.91-0.97. The Bland-Altman plot showed no systematic differences, and the RCI for the total WORC index was 7.6%. Conclusion: The Spanish version of the WORC index is a valid and reliable tool for evaluating quality of life in patients with RCD and may be used in Spanish speaking countries like Colombia. Level of evidence: Basic Science Study, Development or Validation of Outcomes Instruments/Classification Systems.

Abstract Background Self-reported measures play a crucial role in research, clinical practice and health assessment. Instruments used to assess self-reported health-related quality of life (HRQoL) need validation to ensure that they measure what they are intended to, detect true changes over time and differentiate between subjects. A generic instrument measuring HRQoL adapted for use among people living with cancer in Uganda is lacking; therefore, this study aimed to evaluate the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 in patients with cancer in Uganda. Methods Adult patients with various types of cancer (n = 385) cared for at the Uganda Cancer Institute answered the EORTC QLQ-C30 in Luganda or English language, the two most spoken languages in the country. The two language versions were evaluated with regard to data quality (floor and ceiling effects and missing responses), reliability (internal consistency) and validity (construct, known-group and criterion). Construct validity was examined through confirmatory factor analysis (CFA). Mean scores were compared between groups differing in disease stage to assess known-group validity. Criterion validity was examined according to associations between two QLQ-C30 subscales (Global quality of life and Physical function) and the Karnofsky Performance Scale (KPS). Results Floor and ceiling effects were observed for several scales in the Luganda and English versions. All EORTC scales with the exception of Cognitive function (Luganda α = 0.66, English α = 0.50) had acceptable Cronbach’s alpha values (0.79–0.96). The CFA yielded good fit indices for both versions (RMSEA = 0.08, SRMR = 0.05 and CFI = 0.93). Known-group validity was demonstrated with statistically significant better HRQoL reported by patients with disease stages I–II compared to those in stages III–IV. Criterion validity was supported by positive correlations between KPS and the subscales Physical function (Luganda r = 0.75, English r = 0.76) and Global quality of life (Luganda r = 0.59, English r = 0.72). Conclusion The Luganda and English versions of the EORTC QLQ-C30 appear to be valid and reliable measures and can be recommended for use in clinical research to assess HRQoL in adult Ugandans with cancer. However, the cognitive scale did not reach acceptable internal consistency and needs further evaluation.

Cuff Tear

BACKGROUND: Rotator cuff tear (RCT) is a common injury of the shoulder, especially middle-aged people. Nonoperative treatment, cortisone injections are only effective at an early stage. Open surgery causes postoperative atrophy of the deltoid muscle, so results are limited. Arthroscopic rotator cuff repair surgery has been performed in Vietnam for about ten years, with many advantages such as the ability to accurately assess the lesions and less invasive procedure. In order to have a clearer view, we performed a mid-term assessment of the effectiveness of this surgery. AIM: Evaluate results over 2 years of patients with rotator cuff tears treated with arthroscopic surgery and their quality of life. METHOD: A group of 30 patients were diagnosed with RCT and surgery by arthroscopy to treat at Hanoi Medical University Hospital and Saint Paul Hospital between Jun 2015 and April 2017. The results of the surgeries were assessed by the degree of pain, muscle power, motion of the shoulder joint according to UCLA shoulder score. Evaluate the quality of life through the Rotator Cuff-Quality of Life (RC-QoL) index. RESULTS: The average age was 60.7 years. Female / male ratio was 1.3. Thirty-six months ± 6.41 was the average follow-up time (min 27 – max 50 months). The shoulder function is recorded according to UCLA has an average score of 30.9, therein good and excellent result were 90 %. The mean RC-QoL index was 91.5%. CONCLUSION: Treatment of RCT by arthroscopic surgery that has been evaluated for a minimum of 2 years follow-up showed good results and high quality of patient’s life.

Background Although evidence suggests that the EuroQoL-5 dimension (EQ-5D) and Short Form-6 dimension (SF-6D) have equivalent psychometric properties in people with depression, there is some evidence that the EQ-5D may lack responsiveness in certain populations with depression. Aims To examine the psychometric properties of the five-level EQ-5D (EQ-5D-5L) and SF-6D measures of health-related quality of life in a representative sample of pregnant women with depression. Method Data were taken from a cohort of pregnant women identified at or soon after the first antenatal care contact and followed-up at 3 months postpartum. Health-related quality of life was measured using both the EQ-5D-5L and the SF-6D at baseline and follow-up. We examined acceptability and conducted psychometric validation in the aspects of concurrent validity, convergent validity, known-group validity and responsiveness in 421 women with available data. Results The EQ-5D-5L and SF-6D have similarly high levels of acceptability. However, concurrent validation shows a lack of concordance between the EQ-5D-5L and SF-6D. The EQ-5D-5L tends to be higher than the SF-6D in individuals with better health states. The SF-6D tends to be higher than EQ-5D-5L in individuals with poorer health states. Convergent and known-group validity are comparable between the two utility measures. Longitudinally, women who recovered show larger increase in SF-6D utilities than those who did not recover at follow-up. With the EQ-5D-5L, this is not the case. Additionally, the ceiling effects were more apparent in the EQ-5D-5L. Conclusions The effectiveness of perinatal mental health interventions may be better captured by the SF-6D than the EQ-5D-5L but this needs to be cross-validated in more studies.

Background: Neuromuscular disorders affect physical and mental aspects of a patient and in other words alter the patients’ quality of life (QOL). In the present study, we investigated the validity and reliability of the Persian version of Individualized Neuromuscular QOL (INQOL) to provide a better insight into patients’ QOL. Methods: Original version of the INQOL was translated backward and then forward. The resultant Persian version and a standard questionnaire, 36-Item Short Form Health Survey (SF-36), were then given to 83 participants with neuromuscular disorders. Internal consistency, known-group validity, concurrent validity, and test-retest reliability were assessed. Results: The scores of matched sections for QOL in the two questionnaires were favorably correlated (P < 0.05). Correlation between test and retest scores was also significant (P < 0.05). Moreover, the Cronbach’s alpha of 0.82 was representative of robust internal consistency between INQOL covering sections. Conclusion: The Persian version of the INQOL can be used in clinical and research practice to detect changes in QOL which are related to neuromuscular disorders, due to its favorably reliable and valid characteristics.
