Cross-cultural evaluation of the Michigan Hand Outcomes Questionnaire: a systematic review.

This systematic review aims to provide a comprehensive synthesis and in-depth analysis of the quality of the different cross-cultural versions of the MHQ. This study was conducted using Pubmed, Web of Science, CINAHL and SCOPUS databases to identify cross-cultural validation studies of the MHQ. Methodological quality, quality of evidence and criteria for good measurement properties of these studies were applied for each psychometric property. Quality assessment and data extraction were performed independently by two reviewers according to the COnsensus-based Standards for selection of health Measurement INstruments (COSMIN) guidelines. A total of 493 articles were identified, of which 22 were included and 20 were analysed.Of the six properties analysed, responsiveness and hypothesis testing for construct validity had the highest methodological quality and quality of evidence, and met the criteria for good measurement properties. The lowest quality properties were measurement error and internal consistency. The different cross-cultural versions of the MHQ were found to be reliable, valid and able to detect clinical change. The lack of development of measurement error, formulation of an a priori hypothesis or structural validity affects the detection of small clinical changes and their discriminative capacity.

Cross-cultural adaptation, reliability, validity and responsiveness of the Michigan Hand Outcomes Questionnaire (MHQ-Sp) in Spain.

BACKGROUND: The Michigan Hand Outcomes Questionnaire (MHQ) is a self-report tool widely recognized for measuring the health status of patients with hand and wrist problems from a multidimensional perspective. The aim of this study is to translate and culturally adapt the MHQ and validate its psychometric properties of validity, reliability, and responsiveness for different hand problems in Spain. METHODS: The MHQ was translated and culturally adapted following the recommendations of the American Association of Orthopaedic Surgeons. The validation process adhered to the current Consensus-Based Standards for the Selection of Health Status Measurement Instruments (COSMIN) group and was conducted on 262 hand patients. Reliability was assessed through internal consistency using Cronbach's alpha. The study evaluated the test-retest reliability of the measurements using the intraclass correlation coefficient (ICC). Additionally, the measurement error was calculated using the standard error of measurement (SEM) and smallest detectable change (SDC). To assess the structural validity, confirmatory factor analysis (CFA) was employed, while construct validity was evaluated using Pearson's correlation coefficient. Finally, responsiveness was assessed using effect size (ES), standardized response mean (SRM), and minimum clinically important difference (MCID). RESULTS: The reliability of the test was confirmed through internal consistency analysis, with a good Crombach's Alpha (0.82-0.85), and test-retest analysis, with good values of ICC (0.74-0.91). The measurement error was also assessed, with low values of SEM (1.70-4.67) and SDC (4.71-12.94)). The CFA confirmed the unidimensionality of each scale with goodness of fit indices, while the MHQ showed a high and negative correlation with DASH (r = - 0.75, P < 0.001) and DASH-work (r = - 0.63, P < 0.001) and was irrelevant with EQ-5D (r = - 0.01, P > 0.005) and grip strength (r = 0.05, P > 0.005). At week 5, all 222 patients across the three diagnosed hand subgroups showed moderate to high values above 0.92 for ES and SRM, with one MCID above 6.85. CONCLUSIONS: The MHQ-Sp was culturally adapted, and the results of this version showed good reliability and validity as well as high responsiveness for a wide range of hand conditions after surgical or conservative treatment in Spain.

Analysis of Structural Characteristics and Psychometric Properties of the SarQoL® Questionnaire in Different Languages: A Systematic Review.

BACKGROUND: Sarcopenia is the gradual and global loss of muscle and its functions. Primary sarcopenia is associated with the typical changes of advanced aging and affects approximately 5-10% of the population. The Sarcopenia and Quality of Life (SarQoL®) questionnaire is composed of 55 items, 22 questions, and is organized into seven domains of quality of life. The main objective of this systematic review was to analyze the structural characteristics and psychometric properties of it, as well as to classify its measurement properties, its methodological quality, and the criteria as good measurement properties of the adaptations and validations made on the SarQoL® questionnaire in different languages. METHODS: A systematic review was carried out in the PUBMED, Web of Science, Cinahl, LatinIndex, and SCOPUS databases. The keywords used were: "SarQoL", "assessment", "sarcopenia", "geriatric", "PROM", "quality of life", and "questionnaire", using the Boolean operator "AND". All articles published up to 15 January 2022 were considered. Methodological quality and psychometric properties were assessed based on the COSMIN guidelines and the guidelines and general recommendations of PRISMA. Documents published in languages other than English were excluded, as well as versions of the SarQoL® published in the form abstracts for conferences when the full text was not available. RESULTS: A total of 133 articles were identified, 14 of which were included. The evaluated questionnaires and the structural characteristics and psychometric properties of each of them were collected. CONCLUSION: The different cross-cultural versions of the questionnaire showed good basic structural and psychometric characteristics for the evaluation of patients with sarcopenia.
