Hj. Kopecky et al., RELIABILITY AND VALIDITY OF THE OVERT AGITATION SEVERITY SCALE IN ADULT PSYCHIATRIC-INPATIENTS, Psychiatric quarterly, 69(4), 1998, pp. 301-323
An instrument, that validly and reliably identifies and measures agita
tion is required to evaluate environmental modifications, interpersona
l strategies, psychopharmacological interventions, directed toward man
aging these commonly occurring and highly-disabling emotions and behav
ior. The conceptualization of agitation on a continuum from anxiety to
aggression provides a practical frame-work for guiding clinical pract
ice toward the early identification and intervention of agitation. The
results of this study established the reliability and validity of the
Overt Agitation Severity Scale (OASS) in measuring agitation severity
in young adult psychiatric inpatients based on objectifiable vocaliza
tions and motoric upper and lower body behaviors. The OASS differs fro
m other agitation scales in its ability to capture both the intensity
and frequency of observable behavioral manifestations of agitation, as
opposed to subjective interpretations and a diffuse range of symptoms
and problem behaviors.
