Translation and validation of a Hebrew version of the Western Ontario Shoulder Instability index

Abstract

Background The Western Ontario Shoulder Instability index (WOSI) is a questionnaire designed to measure health-related quality of life in patients with shoulder instability. The aim of the current study was to translate the WOSI into Hebrew and assess its psychometric properties. Methods The WOSI was translated into Hebrew according to World Health Organization guidelines. Twenty-five patients completed the WOSI and the Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire 2 weeks and 2 months after surgical shoulder stabilization. Internal consistency (Cronbach’s α), criterion validity (Pearson’s correlation coefficient with DASH), responsiveness, and floor and ceiling effects were assessed. Results Cronbach’s α was 0.88–0.95 for total WOSI (range 0.68–0.95 for different sections). Strong correlation with DASH score ( r = 0.76–0.84) indicated good criterion validity. Changes between baseline and follow-up for WOSI and DASH scores were moderately correlated ( r = 0.68), suggesting moderate responsiveness. Some items demonstrated floor and ceiling effects, especially at baseline, but no floor or ceiling effects were observed for total WOSI or for the WOSI sections. Conclusions The results of the current study demonstrate that the Hebrew version of the WOSI is a valid instrument that can be used to assess disability in patients with shoulder instability. Additional studies are warranted to assess its psychometric properties among various subpopulations. Trial registration The study was pre-registered at the ClinicalTrials.gov website, registration number NCT02978365 .

Reliability, Validity and Responsiveness of the Polish Version of the Western Ontario Shoulder Instability Index (WOSI-PL) in Patients after Arthroscopic Repair for Shoulder Instability

“…The majority of the hypotheses specified in the methodology were proven. The findings show that the psychometric properties of the WOSI-PL correspond to those reported for the original version of the tool and WOSI adaptations developed in other countries [ 3 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. A summary of the psychometric properties of all language versions of the WOSI questionnaire is shown in Table S1 .…”

“…The WOSI is one of most frequently used questionnaires for shoulder instability with very good psychometric properties [ 6 , 8 ]. It has been validated in twelve languages and in fourteen cultures so far [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Bejer et al, (2019) published the results of the translation and cultural adaptation of the WOSI into Polish [ 26 ].…”

“…Yuguero et al found, in the Spanish version, a greater measurement error than in the other versions (SEM = 23% and MDC = 76%) [ 18 ]. Other WOSI validation studies did not calculate SEM or MDC [ 3 , 9 , 10 , 11 , 12 , 14 , 17 , 21 , 22 , 23 ].…”

“…Whittle et al, in their systematic review, also strongly recommend using WOSI for patients with shoulder instability [ 6 ]. To our knowledge, the WOSI has been translated to Swedish [ 9 ], German [ 10 , 11 ], Japanese [ 12 ], Italian [ 13 ], Brazilian, Portuguese [ 14 ], Dutch [ 15 , 16 ], French—validated on a Canadian and Swiss population [ 17 ], Spanish [ 18 ], Danish [ 19 ], French—validated on a French population [ 20 ], Turkish [ 21 ], Hebrew [ 22 ], Arabic [ 23 , 24 ] and European Portuguese [ 25 ]. In Poland, translation and cultural adaptation of the WOSI was conducted by Bejer et al, in 2019 [ 26 ].…”

The Relationship Between Fear Avoidance Beliefs, Muscle Strength, and Short-Term Disability After Surgical Repair of Shoulder Instability

“…27 The DASH results in this study were also used to validate a Hebrew version of the WOSI. 29 The WOSI is a designated instrument to assess quality of life in patients with SI. 30 It consists of 21 items of 4 domains (physical function, sports/recreation/work, lifestyle, and emotional wellbeing), each item scored 0 to 100 on a visual analog scale.…”
