“…Most state commitment statutes today specify that patients may be involuntarily admitted to a hospital only on grounds of danger to self, danger to others, or (in many states) grave disability, and then only if the condition results from mental disorder. Judicial interpretations of these statutes indicate that the common denominator, i.e., the only legitimate basis for civil commitment, is danger due to mental disorder (Segal, Watson, Goldfinger, & Averbuck, 1988a, p. 748). Recent research on civil commitment indicates that clinicians employ a shared concept of dangerousness that can be defined in specific terms, related to psychiatric disorder, and used to predict civil commitment in the psychiatric emergency room (Segal et al, 1988a, 1988b, 1988c).…”
