J Psychiatr Ment Health Nurs. 2012 Oct;19(8):722-8. doi: 10.1111/j.1365-2850.2011.01848.x. Epub 2012 Jan 10.


Nutrition screening is the first-line approach to addressing the nutritional needs of service users and has been recommended as best practice by several authoritative and regulatory bodies. A simple and comprehensive screening tool, the St Andrew's Nutrition Screening Instrument (SANSI), was developed for use in an inpatient secure psychiatric setting. The aim of this study was to test the screening tool for reliability and validity. This study identified SANSI as reliable and valid for use in secure psychiatric settings for adolescents and adults. This should give confidence to regulatory and commissioning organizations, that the nutritional risk for patients in an organization which serves a diverse mental health population is being correctly identified, raising staff awareness and allowing appropriate action to be planned.
