A comparison of 15 theories of suicide

A method is illustrated for studying the lives of suicidal individuals. Each of 15 theories of suicide is operationalized with 10 statements. These 150 statements are then rated as present or absent in the lives of 30 famous suicides for whom a biography is available. The theory of Aaron Beck is found to be most applicable to the suicidal lives and that of Sigmund Freud least applicable. A factor analysis has identified five clusters of theories; and the age, sex, national origin, era, and experience of loss are found to be associated with scores of the 30 suicides on the 15 theories.
