Compared psychological, familial, and demographic data for 42 suicidal, 16 suicide ideation, and 42 control pediatric patients. Chaotic families, behavior problems, depression, constriction, and lack of insight differentiated suicide attempters from controls. Suicide ideation group was similar to both attempters and controls. Constriction was only predictor differentiating serious from less serious suicide attempt. (Author/NB)
