Verbal de-escalation techniques have been shown to decrease agitation and reduce the potential for associated violence in the emergency setting .
OBJECTIVE To present the essential guidelines for non-pharmacological management of patients with psychomotor agitation in Brazil .
Validation of the behavioural activity rating scale (BARS): A novel measure of activity in agitated patients
We report psychometric results of the  Behavioural Activity Rating Scale ( BARS ) using data from three Phase III clinical trials of intramuscular ziprasidone in acutely agitated patients with psychosis ( Studies 1 and 2 ) or in stable psychotic patients ( Study 3 ) . Convergent validity and divergent validity were assessed with baseline data from Studies 1 and 2 in subjects with acute agitation . To investigate convergent validity , we sought Pearson and Spearman correlation of BARS scores with scores on the Clinical Global Impression of Severity ( CGI-S ) Scale and a predefined cluster of agitation-related items from the Positive and Negative Syndrome Scale ( PANSS ) . For divergent validity , we sought Pearson and Spearman correlation between BARS scores and a predefined cluster of PANSS items measuring negative symptoms . Discriminant validity was investigated with the help of subjects with moderate psychopathology ( Study 3 ) . Wilcoxon rank-sum and two- sample t tests determined whether mean ( or median ) BARS scores differed between subjects with acute agitation ( Studies 1 and 2 ) and moderate psychopathology ( Study 3 ) . Responsiveness to treatment effect and rater reliability were also evaluated . In Study 2 , Pearson correlation coefficients of BARS scores with PANSS agitation items and CGI-S were moderate ( convergent validity ) and statistically significant ( P<0.005 ) . The correlation between BARS scores and PANSS negative component scores was low ( divergent validity ) . Treatment effect size was larger for BARS than for PANSS agitation items and CGI-S ( responsive to treatment differences ) . Virtually perfect inter- and intra-rater reliability was achieved . Study 1 produced similar results . BARS showed psychometrically valid properties for measurement of behavioral activity in acutely agitated patients with psychosis
