Psychometric properties of the work environment impact scale: a cross-cultural study.

This study examined the psychometric properties of the Work Environment Impact Scale in the United States and Sweden. Thirteen American and four Swedish occupational therapists used the scale (in English and Swedish respectively) to rate 21 (11 American and 10 Swedish) subjects. Results of a Rasch analysis of the data, indicate that the items work well together to measure the construct of work environment impact. The scale is also suitably matched to the clients in this study and effectively discriminated different levels of work environment impact. The findings also suggest that both language versions of the scale are equivalent and that the scale is culture-free.
