Bowlby's 44 thieves study
Aim: This study examined the links between affectionless psychopathy and maternal deprivation.
Procedure: Bowlby analysed case histories of his patients in the Child Guidance Clinic, London. All children were
emotionally maladjusted. 88 children studied - 44 had been caught stealing, the other half were the control group.
Bowlby interviewed the thieves for signs of 'affectionless psychopathy' (lacking signs of affection, shame and responsibility) and interviewed families to find out about prolonged separation from their mother.
