The Spanish version of the Manchester Nurse Rating Scales

Abstract

Introduction. There is no Nursing-staff Mania Rating Scale adapted to the Spanish language. The present work is the result of the adaptation we have carried out.

Methodology. The scale has been translated and the back-translation compared with the original version. It has been applied on 670 occasions to a sample of 59 patients. Simultaneously the patients were rated with the Manic Interpersonal Interaction Scale, two versions of the Visual Analogue Scale and the Numeric Rating Scale.

Results. The coefficient Alpha of Cronbach is 0.94. The interrater’s correlation coefficient for the total of the scale is 0.84. The factorial analysis gives a single factor that explains 65% of the variance. The Area under the ROC Curve is 0,87.

Conclusions. The scale shows excellent psychometric properties, with great homogeneity of the scale items and good discriminate properties between bipolar patient and those affected by other psychoses.
