Psychometric properties of the full and short version Nursing Home Survey on Patient Safety Culture (NHSOPSC) instrument: a cross-sectional study assessing patient safety culture in Norwegian homecare services.

This study provides a first proposal for a short-version Homecare Services Survey on Patient Safety Culture instrument to assess patient safety culture within homecare services. It needs further improvement, but provides a starting point for developing an improved valid and reliable short-version instrument as part of assessment of patient safety and quality improvement processes.
