Introduction The reviews of recent literature reveal that there is no really useful scale to monitor patient condition. However, the English version of the Nursing Observed Illness Intensity Scale (NOIIS) has demonstrated to be an objective and quick evaluation of patient status in psychiatric inpatients units. In this context, our aim is demonstrate the usefulness, reliability, and validity of Spanish version of the NOIIS in mental health units. Methods After the translation and re-translation of NOIIS, 34 patients completed it. To evaluate the reliability, the scale was administered by two professionals. To control the validity data were obtained from other psycho-pathological scales (BPRS, pathological dimensional scale DSM-5, ICG scale, and the social functioning scale SIX). Results The Cronbach Alpha reliability showed higher values of 0.89 by item, and 98% for total scored. We found a 70% Pearson correlation between NOIIS and BPRS (P = .00), and to a lesser extent between NOIIS and ICG and with the DSM-5 pathological dimensional scale. In addition, we observed a negative correlation between the NOIIS and SIX scale. Conclusion Even though our sample was small, the results show that the Spanish version of the NOIIS is applicable in the hospital setting. Furthermore, it has also demonstrated its reliability between raters, and the validity compared to other scales used in mental health.
