A reliable prototype index, Three Ratings of Involuntary Admissibility (TRIAD), was developed to reflect the way psychiatric emergency room clinicians apply legal criteria for involuntary commitment. The interrater reliability coefficients--Pearson's r--of the TRIAD system for rating patients are 0.94, danger-to-self score; 0.89, danger-to-other score; 0.77, grave-disability score; and 0.89, total-admissibility score. TRIAD scores accounted for 82 percent of 89 disposition decisions in two metropolitan county hospital psychiatric emergency rooms. Study results indicate that (1) psychiatric emergency room clinicians shared constructs of danger to self, danger to others, and grave disability; (2) these constructs are reliably applied in actual cases; (3) TRIAD is a valid reflection of these constructs; and (4) case disposition is predictable from the severity of the patient's status with regard to these criteria.
