Data from therapists who were treating 26 patients when they committed suicide were utilized to identify signs that warned of a suicide crisis. 3 factors were identified as markers of the suicide crisis: a precipitating event; one or more intense affective states other than depression; & at least one of three behavioural patterns: speech or actions suggesting suicide, deterioration in social or occupational functioning, & increased substance abuse. Problems in communication between patient & therapist were identified as factors interfering with crisis recognition. Evaluation of the identified affects & behaviours may help therapists recognize a suicide crisis. (23 refs.)
