This article reports an analysis of the internal properties of an instrument that has been widely used to measure the quality of nursing care. Three-fourths of the 106 questions in the instrument failed to meet minimum standard psychometric test criteria. The better questions dealt with housekeeping rather than nursing duties; the instrument would appear to be reliable as a measure of cleanliness and orderliness, but not of actual nursing care.
