The Missouri Inpatient Behavior Scale.

The Missouri Inpatient Behavior Scale (MIBS) is described, and data are presented from the Missouri automated mental health information system (N = 12,106). The factor structure for MIBS was replicated and shown to be robust. Data on intrascale consistency and interscale correlations are presented, as well as a validity study that showed MIBS to be sensitive to changes on acute-receiving services and a comparison of MIBS and NOSIE-30 scores.
