Evaluated whether adolescent suicide attempters (n=30) would have deficits in interpersonal problem solving and relation between social problem solving, suicide intent, and medical lethality. Compared with 30 psychiatric and 30 normal controls, adolescents who attempted suicide exhibited poorer social problem-solving abilities. Suicide attempters brought more maladaptive cognitive-emotional-behavioral response sets to problematic situations. (Author/NB)
