A prospective study of postpartum psychoses in a high-risk group. 4. Relationship to life situation and experience of pregnancy.

Within a sample of 88 pregnant women with a history of nonorganic psychosis, the woman's life situation and experience of pregnancy, assessed through interviews during pregnancy, were studied in relationship to the development of 25 postpartum psychotic episodes (PPPs) occurring during the first 6 months postpartum. Neither Early nor Later Onset PPPs were associated with more current material situational problems, interpersonal difficulties, lack of relatives' support for the pregnancy, the woman's negative attitude toward the pregnancy or her experience of somatic health complaints. Contrary to expectation, PPP cases reported several more positive situational, attitudinal and experiential characteristics than did risk cases not developing PPPs. A number of different possible explanations for this finding are discussed.
