In addition, comorbid diagnoses are frequently identified
among alcoholics who attempt suicide. Roy et al. (165), for example,
found the most common comorbid psychiatric diagnoses among alcoholic
suicide attempters to be major depression, antisocial personality
disorder, substance abuse, panic disorder, and generalized anxiety
disorder. Hesselbrock et al. (166), in a sample of 321 inpatients
(231 men, 90 women) in alcoholism treatment centers, found that
suicide attempters typically had multiple psychiatric diagnoses
(e.g., depression, antisocial personality disorder, and substance
abuse) and more severe psychiatric symptoms than nonattempters.
Two-thirds of alcoholics who attempted suicide had a lifetime diagnosis
of major depressive disorder, and most reported symptoms of depression
within 2 weeks of the interview. Alcoholic suicide attempters tended
to have a parental history of alcoholism, to have begun abusing
alcohol at an early age, and to have abused other substances in
addition to alcohol.
