A study was made of 91 women who following a suicidal attempt were admitted to a psychiatric hospital in Antrim, Northern Ireland, in 1971. The personality, psychiatric condition, intelligence, civil state, social class and religion of these patients were analyzed and compared with the same factors in a group of 100 female patients treated after a suicidal attempt in the same hospital in 1962 and 1963. The aim of the inquiry was to find out: (1) whether there were any changes in the incidence of suicidal attempts and in the methods used now and in 1962; (2) whether our hypothesis that suicidal behaviour is gain-motivated would be confirmed by the 1971 group of women. The findings in both groups seem to suggest that (1) the incidence of the suicidal attempts has almost doubled in the last decade; (2) there was a 20-percent decrease in alcohol abuse, and a 25-percent increase in drugs abuse within the last 10 years; (3) it would appear that, with the exception of the psychotic and psychopathic patients, in both groups of patients their suicidal behaviour was goal- and gain-directed, and aimed at changing the environment to the patient's benefit.
