from Part II - Social factors and the onset of psychosis
Published online by Cambridge University Press: 07 December 2009
Introduction
Back in the 1950s and 1960s, it was popular to insinuate that the development of mental health problems, particularly schizophrenia, was a result of being brought up in a disturbed family (see Chapter 8). Unfortunately, this led to a family-blaming culture based on little evidence, which, not surprisingly, was met with anger from relatives' support groups. Subsequently, few psychosis researchers have explored potential risk factors relating to the family. However, in the past few years there has been a resurgence of research into how the family environment and adverse childhood experiences may be linked to later development of psychosis (see also Chapter 8). This area of research appears to have come almost full circle and careful consideration of recent research is essential if simplistic and potentially harmful conclusions are to be avoided. In this chapter, we focus on childhood adversity, and begin with a review of the most commonly researched aspects of early adversity and trauma.
Summary of existing literature
Separation from parents or loss of at least one parent
Recent investigations employing reasonably robust methodologies have found a twofold to threefold increased risk of adult psychosis in those who experienced long-term separation from, or death of, at least one parent during childhood, independent of a variety of confounders, including a parental history of mental illness (e.g., Morgan et al., 2007).
