The possibility of a relationship between early parental loss and mental illness, suicide, or delinquency in later life is a well-known, although by no means universally accepted, theory. In this investigation, we have attempted to compare patients with carefully matched controls and to investigate, when possible, the various categories of depression separately. Also, as we felt that a study concerned with childhood deprivation based solely on the physical absence of parents would tell us little of the daily emotional experiences of the child, we have attempted to take into account the quality of the family relationships present in childhood.
