The Italian Version of the Michigan Hand Outcomes Questionnaire (MHQ): Translation, Cross-Cultural Adaptation and Validation

Abstract

Background: Patient-reported outcome measures are largely used in clinical practice and scientific community. Michigan hand questionnaire (MHQ) is widely recognized as a standardized reliable instrument for the assessment of any kind of hand disorders. Aim of the study: translation, cross-cultural adaptation and validation of the Italian version of MHQ. Methods: The study was composed by two phases. Phase 1 consisted in translation and cross-cultural adaptation of MHQ, from original language version (English) into Italian, according to the standard procedure of translation and back translation. The final Italian version of MHQ was tested on 136 Italian patients with hand disorders (Phase 2), in addition to Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, Visual analogue scale (VAS) for pain assessment and grip strength, to psychometric properties of the new version, 55 patients repeated the questionnaire after 7 days for test-retest to assess the reproducibility of the questionnaire. All data were subsequently analyzed (descriptive statistics, multitrait analysis, reliability and construct validity assessment). Results: Phase 1 was performed without major problems, thus the final Italian version was approved for Phase 2. The questionnaire was clear and easily understood (missing data 0–2.9%). Multitrait analysis brought very good results for each outcome measure. High reliability (Cronbach’s alpha: 0.91–0.99) and very good reproducibility (Intraclass correlation coefficients: 0.83–0.98) were revealed. High to moderate correlation was found between MHQ and DASH, grip strength and VAS. Conclusions: The Italian version of MHQ has demonstrated to be reliable and valid.

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

“…These values were lower than the original MHQ [ 10 ] (0.86–0.97) or other versions of DASH > 0.90 [ 68 , 69 ]. The findings suggest a satisfactory correlation between the items while avoiding redundancy compared to other versions [ 26 , 29 , 64 , 70 ]. It is important to note that values above 0.90 are common in large instruments, with this index being sensitive to the nunber of ítems [ 68 ].…”

“…The method employed was that developed by Beaton et al[ 18 ], consistent with other adapted versions of the MHQ [ 11 , 19 , 20 , 22 – 26 , 28 – 31 , 62 – 64 ]. According to the expert assessment, Kendall's 0.85 w values indicated a high coefficient of concordance, whereas two other versions [ 25 , 26 ] considered an Item Objective Congruence (IOC) of 0.5 to be acceptable [ 65 ].…”

Surgical treatment of carpometacarpal thumb arthritis with trapeziectomy and intra-tendon (FCR) suspension with one-loop APL: comparative cohort study

“…Pre-operative dataset included general demographic, clinical history, Charlson Comorbidity Index (CCI) score, X-rays of both hands (anterior–posterior, lateral and oblique view), thumb opposition score of Kapandji, strength measured through dynamometers (grip, lateral pinch and tip pinch strength), Michigan Hand Outcome (MHQ) [ 17 ] and DASH questionnaires [ 18 ], pain. Post-operative dataset included X-rays of the operated hand (anterior–posterior, lateral and oblique view) for the evaluation of suspension loss, thumb opposition score of Kapandji, strength, Michigan Hand Outcome (MHQ) and DASH questionnaires, pain, general satisfaction.…”
