Development, adaptation and psychometric assessment of the extended brisbane practice environment measure for nursing homes (B-PEM-NH) for use in the Norwegian setting.

Care workers' work environment is known to be associated with patient and nurse outcomes. To our knowledge no questionnaire is available for assessing this environment for all care workers in the Norwegian nursing-home setting. This paper describes the development, adaptation and assessment of such a questionnaire: the extended Norwegian version of the Brisbane Practice Environment Measure for Nursing Homes (B-PEM-NH). This version was developed and assessed using semistructured interviews, a reference group meeting, translation, adaptation, and pretesting, and psychometric assessment including exploratory and confirmatory factor analyses, and retest. We tested hypotheses to assess relations to other variables. The final factor solution comprised 41 items and 9 factors: interpersonal leadership, professional development, resources, professional leadership, input and acknowledgement, patient and next-of-kin focus, multidisciplinary collaboration, language misunderstandings, and feeling unsafe. The assessment showed that the B-PEM-NH had good psychometric properties, suggesting that the questionnaire is suitable for application in similar settings.
