- 44 Juvinille Thieves were studied (aged between 5 and 16 years old).
- Bowlby worked at the detention centre where the offenders were currently at.
- 17 out of the 44 had been seperated from mother before the age of 5.
- 14 of these 17 were classed as affectionless psychopaths (no remores or guilt).
- 12 of these 14 had suffered long maternal seperation.
- Bowlby concluded their behaviour was caused by maternal seperation.
- This study supported his theory that maternal seperation has negative consequences (maternal deprivation hypothesis)
- However this study may have been prone to reseracher bias, as Bowlby worked with the juvinille thieves.

Evaluation of Disruption of Attachment
- seperation does not always disrupt bond (foster parenting).
- RD - reactive attachment disorder = Foollan and Minnis - rexamined Bowlby's 44 Thieves and compared to control concluded that early disruption is a factor of RAD.
- Correlational or Causal? - unethical to control human contact so rely on case studies and reterospective information e.g. 44 thieves. Reterospective = unreliable
- studies into attachment provide essential information about attachment, however they may not be applicable now as parents stay with children in hospital.
- Bowlby's Theory's were good for the time (war) when men were away from children. But when times change, theories are questioned.
