Background: The WHODAS 2.0 questionnaire is used internationally to assess a person’s functioning and limitations. The objectives of this study were (1) to evaluate the validity of the translated Hebrew version of the 12-item WHODAS 2.0 questionnaire among Hebrew speakers and (2) assess the reliability and validity of the Hebrew version in a sample of workers with and without hand injuries (HI).

Methods: The translated questionnaire was administered to 155 uninjured subjects (UI) and 77 male workers with HI. Internal consistency was assessed using Cronbach's alpha. Test-retest reliability was administered to UI subjects and calculated by the intra-class correlation coefficient (ICC agreement). Validity was evaluated by correlating the 12-item WHODAS 2.0 to the short-form of health survey (SF-12) and comparing the 12-item WHODAS 2.0 scores and the Quick Disability of Arm, Shoulder and Hand (QDASH) Outcome Measure in the HI group.

Results: The Cronbach’s alpha of the WHODAS 2.0 for the entire sample was α = .83. The ICC agreement for test-retest reliability was .88. A positive significant correlation was found between the 12-item WHODAS 2.0 and the QDASH (rs = 0.53, P < .005).

Conclusions: The results support the reliability and validity of the Hebrew translated version of the 12 item WHODAS 2.0.

Application of Practice: Using measurement tools that assess activities and participation after HI are essential part of the rehabilitation process. It is recommend considering the WHODAS 2.0 since it enlarges the domains of activities and participation that enables a better implementation of the ICF model.
