PROBLEM
The aims of this study were two-fold. The first goal was to construct, field teat and standardize a multidimensional behavior inventory for the description of observable psychotic patient behavior in a hospital setting. The second goal was to test a set of hypotheses concerning psychotic reaction patterns that have been repeatedly identified in multiple factor studies of interview and ward behavior. If the more significant reaction patterns would be evidenced on the ward as well as in the interview situation, then an inventory could be developed for use by nurses and aides who actually have a greater opportunity for observing patient behavior than do the relatively few psychologists or psychiatrists on most hospital staffs.
The hypothesized primary constructs which the behavior inventory was designed to measure were Resistiveness and Motor Disturbances (catatonic-like behavior), Withdrawal vs. Sociability, Perceptual Distortions, Conceptual Disorganization, Melancholy Agitation, Paranoid Projection, Hostile Belligerence and Lack of Interest in Self or Others. In addition an interpersonal parameter of Dominance vs.
Submissiveness was postulated. All patterns except the last have been isolated in at least two factor studies of rated interview and ward behavior. Four higher level or second order constructs were also hypothecated: Withdrawal, Belligerence, Thinking Disorganization and Intropunitiveness. c2, 6 l 'I)
