Methods Data from the observational NATURA study were used. This research describes trends in the use of treatments in patients with acute psychotic episodes and agitation seen in emergency departments. Exploratory principal component factor analysis was performed. Spearman s correlation and regression analyses linear regression model as well as equipercentile linking of Clinical Global Impression of Severity CGI-S Agitation and Calmness Evaluation Scale ACES and PANSS-EC items were conducted to examine the scale s diagnostic validity. Furthermore reliability Cronbach s alpha and responsiveness were evaluated. Results Factor analysis resulted in one factor being retained according to eigenvalue 1. At admission the PANSS-EC and CGI-S were found to be linearly related with an average increase of points p on the PANSS-EC for each additional CGI-S point. The PANSS-EC and ACES were found to be linearly and inversely related with an average decrease of points p on the PANSS-EC for each additional point. The equipercentile method shows the poor sensitivity of the ACES scale. Cronbach s alpha was and effect size was . Conclusions The factorial analyses confirm the .
