Including the provider in the assessment of quality care: development and testing of the Nurses' Assessment of Quality Scale - acute care version.

This study was designed to develop a psychometrically sound measure of nurses' evaluation of patient care delivered. The Nurses' Assessment of Quality Scale-Acute Care Version (NAQS-ACV), derived from the qualitative interviews of acute care nurses, was initially 138 items formatted as a Likert-type scale and administered to 1272 nurses from 7 acute care hospitals. After analysis, the scale was reduced to 77 items contained in 8 factors. Reliability estimates for the factors ranged from 74 to 94.
