Content validity and utility of the Assessment of Work Performance (AWP).

In the area of work rehabilitation, many decisions about future interventions for the client are based on the results of various kinds of assessments. Therefore, it is important that the assessment instruments used are adequate, useful, and reliable. The purpose of this study was to investigate the content validity and utility of the instrument Assessment of Work Performance (AWP) which is used to assess an individual's observable (working) skills during work performance, i.e. how efficient and appropriate a client performs a work activity. A questionnaire was answered by 67 respondents who used the AWP in various work rehabilitation settings in Sweden. The result indicates content validity and utility for the AWP that supports further testing of the instrument.
