The Nurses' Observation System for Geriatric Referrals is a 30-item observational scoring system for geriatric inpatients. As constructed, it is scored into six subscales of five items each; however, these six factors have not been empirically validated. A confirmatory factor analysis, performed on a sample of 218 completed forms for 218 geriatric inpatients, did not support the six original factors. Exploratory factor analysis gave a five-factor solution that partially replicated the scale's original factors but which also indicated important differences for interpretation and clinical use.
