Translation, cultural adaptation, validity and reliability of the Greek version of the modified Constant Score.

ABSTRACT: Aim:The purpose of this study was to produce a modified Greek translation of the CS and to test this version in terms of reliability and validity. Materials and methods:Translation of the modified Constant score testing protocol was done according to established international guidelines. Sixty-three patients with shoulder pain caused by degenerative or inflammatory disorders completed the Greek version of CS along with the Greek versions of SF-12 and Quick Dash Scores and the ASES Rating Scale and were included into the validation process. To assess test-retest reliability, 58 individuals completed the subjective part of the test again after 24-36 hours, while abstaining from all forms of treatment; internal consistency was measured using Cronbach's alpha (?); reliability was assessed with test-retest procedure and the use of Interclass Correlation Coefficient (ICC), whereas the validity of the reference questionnaire was evaluated using Pearson's correlation coefficient in relation to control questionnaires. Results:There were no major problems during the forward-backward translation of the CS into Greek. The internal consistency was high (Cronbach's alpha 0.92) while the test-retest reliability for the overall questionnaire was also high (intra-class coefficient 0.95). Construct validity was confirmed with high values of Pearson's correlation between CS and Q-DASH (0.84), SF-12 (0.80) and ASES score (0.86) in respect. Conclusion:A translation and cultural adaptation of CS into Greek was successfully contacted. The Greek version of the modified Constant Score can be a useful modality in the evaluation of shoulder disorders among Greek patients and doctors.

Project description:Freezing of gait is a disabling symptom with a complex episodic nature that is frequently experienced by people with Parkinson's disease (PD). Although China has the largest population with PD in the world, no Chinese version of the freezing of gait questionnaire (FOGQ), the instrument that has been most widely used to assess FOG, has yet been developed. This study aimed to translate and adapt the original version of FOGQ to create a Chinese version, the FOGQ-CH, then assess its reliability, calculate the Minimal Detectable Change (MDC) and investigate its validity. The forward-backwards translation model was adopted, and cultural adaptation included expert review and pretesting. For the reliability study, 31 Chinese native speaking patients with PD were assessed two times in a 7-10 days interval. Internal consistency and test-retest reliability of the FOGQ-CH were measured by Cronbach's alpha (Cα) and the Intraclass Correlation Coefficient (ICC). For the validity study, 34 native speakers of Chinese with PD were included. To explore the convergent validity, relationships between the FOGQ-CH and the Unified Parkinson's Disease Rating Scale Part II (UPDRS II) and Part III (UPDRS III), Timed Up and Go Test (TUGT), Timed Up and Go Test in cognitive task (TUGT-Cog), walking speed (10 MWT speed), and step length (10 MWT step length) in a 10-m Walk Test were tested. To explore predictive validity, the number of falls followed up for 6 months were assessed. The area under the ROC curve (AUC) was employed to test the capacity of FOGQ-CH to discriminate those with falls. From the reliability study, Cα = 0.823, ICC = 0.786. The MDC0.90 = 4.538. From the validity study, the FOGQ-CH showed moderate correlations with UPDRS II (rho = 0.560, p = 0.001), UPDRS III (rho = 0.451, p = 0.007), TUGT (rho = 0.556, p = 0.007), TUGT-Cog (rho = 0.557, p = 0.001), 10MWT-speed (rho = -0.478, p = 0.004), 10MWT-step length (rho = -0.419, p = 0.014), and the number of falls followed up for 6 months (rho = 0.356, p = 0.045). The AUC = 0.777 (p = 0.036) for predicting whether the participants will have multiple falls (two or more) in the following 6 months. The FOGQ-CH showed good reliability and validity for assessing Chinese native speaking patients with PD. In addition, the FOGQ-CH showed good efficacy for predicting multiple falls in the following 6 months.

Project description:Enabling patients with asthma to obtain the knowledge, confidence and skills they need in order to assume a major role in the management of their disease is cost effective. It should be an integral part of any plan for long-term control of asthma. The modified Patient Enablement Instrument (mPEI) is an easily administered questionnaire that was adapted in the United Kingdom to measure patient enablement in asthma, but its applicability in Portugal is not known. Validity and reliability of questionnaires should be tested before use in settings different from those of the original version. The purpose of this study was to test the applicability of the mPEI to Portuguese asthma patients after translation and cross-cultural adaptation, and to verify the structural validity, internal consistency and reproducibility of the instrument. The mPEI was translated to Portuguese and back translated to English. Its content validity was assessed by a debriefing interview with 10 asthma patients. The translated instrument was then administered to a random sample of 142 patients with persistent asthma. Structural validity and internal consistency were assessed. For reproducibility analysis, 86 patients completed the instrument again 7 days later. Item-scale correlations and exploratory factor analysis were used to assess structural validity. Cronbach's alpha was used to test internal consistency, and the intra-class correlation coefficient was used for the analysis of reproducibility. All items of the Portuguese version of the mPEI were found to be equivalent to the original English version. There were strong item-scale correlations that confirmed construct validity, with a one component structure and good internal consistency (Cronbach's alpha >0.8) as well as high test-retest reliability (ICC=0.85). The mPEI showed sound psychometric properties for the evaluation of enablement in patients with asthma making it a reliable instrument for use in research and clinical practice in Portugal. Further studies are needed to confirm its responsiveness.

Project description:STUDY DESIGN:Cross-cultural adaptation and psychometric evaluation. OBJECTIVE:The aim of this study was to translate the Neck Disability Index (NDI) into the simplified-Chinese language and to evaluate the reliability, validity, and responsiveness of the new questionnaire. SUMMARY OF BACKGROUND DATA:Neck pain is a major health problem resulting in major disability. NDI is the most frequently used scale for self-rating of disability due to neck pain. At present, there is no simplified-Chinese version of the NDI. The aims of this study were to culturally adapt and translate the NDI into the simplified-Chinese language (NDI-SC) and to evaluate its psychometric properties in patients with neck pain. METHODS:The NDI was translated into simplified-Chinese version based on established guidelines. A total of 70 patients participated in this study. Patients were asked to complete a set of questionnaires comprising of their demographic information, the NDI-SC, and a visual analog scale (VAS) of pain. Fifty-six patients returned after 1 to 2 weeks to complete the same set of questionnaires and the global rating of change (GROC) scale. Then, the NDI-SC was evaluated for content validity, construct validity, internal consistency, test-retest reliability, and responsiveness. RESULTS:The NDI-SC demonstrated excellent internal consistency (Cronbach ??=?0.92) and good test-retest reliability (ICC2,1?=?0.85). Content validity was confirmed as no floor or ceiling effects were detected for the NDI-SC total score. Construct validity was established with factor analysis revealing two-factor subscales explaining 66% of the variance. The NDI-SC showed a strong correlation with VAS (Rp?=?0.61, P?<?0.001) and a moderate correlation with GROC (Rs?=?0.46, P?<?0.001). The correlation between NDI-SC change scores and VAS change scores was also moderate (Rp?=?0.59, P?<?0.001). CONCLUSION:The results showed that the NDI-SC is a reliable, valid, and responsive instrument to measure functional limitations in patients with neck pain. LEVEL OF EVIDENCE:3.
