Researchers in Minnesota have described and validated the phenomenon of Complexity Compression in qualitative studies of registered nurses. Analysis of themes from this research led to the design of a survey to assess nurses' agreement with variables that contribute to their experience of Complexity Compression. The survey was administered to a random sample of 199 registered nurses in Minnesota. Exploratory factor analysis was used to evaluate the attributes of Complexity Compression and its underlying structure. Three factors emerged that explained 51.4% of the variance in responses: work of nursing, systems, and personal factors. Internal consistency of the factors ranged from .79 to .89. Validity of the survey for assessment of Complexity Compression in hospital-based nurses was supported. The construct of Complexity Compression and its contributing factors will be tested in future studies with nurses in a variety of health care settings.
