A questionnaire to measure inward irritability & outward irritability was given to college students. Inward irritability scores correlated .27 with outward irritability scores. Those students who had attempted suicide had high inward irritability scores; those who had threatened suicide had high inward & outward irritability scores. Results supported the proposition that some suicidal people may have higher levels of outwardly directed anger than nonsuicidal people. (5 refs.)
