The team leaders who volunteered to conduct the survey were trained in its administration and asked to record any feedback relevant to the face validity and acceptability of questions and response options.
While the PRWE was originally developed for wrist disorders, MacDermid and Tottenham (2004) argue that from a functional perspective the wrist and hand are interrelated, and therefore, there is good face validity for its application in a population with hand injuries by changing the word "wrist" to "wrist/ hand" and the name of the scale from PRWE to PRWHE.

Project objectives are to: (1) Develop effective AAC assessment protocols for adults and children with a variety of motor or language impairments; (2) establish content validity of the protocols and refine them as necessary; (3) establish consequential and face validity of the protocols; and (4) disseminate the results of the project.
The next step was the assessment of face validity. Having made grammatical and appearance adjustments and reviewed the overall structure of the questionnaire, it was distributed among 20 patients in the CCUs to assess the simplicity and intelligibility of the items.
