The Integrated Psychosocial Model of Criminal Social Identity (IPM-CSI)

The integrated psychosocial model of criminal social identity attempts to synthesize, distil, and extend our knowledge and understanding of why people develop criminal social identity, with a particular focus on the psychological and social factors involved. We suggest that the development of criminal social identity results from a complex interplay between four important groups of psychosocial factors: (1) an identity crisis which results in weak bonds with society, peer rejection, and is associated with poor parental attachment and supervision; (2) exposure to a criminal/antisocial environment in the form of associations with criminal friends before, during, and/or after incarceration; (3) a need for identification with a criminal group in order to protect one’s self-esteem; and (4) the moderating role of personality traits in the relationship between criminal/antisocial environment and the development of criminal social identity. The model produces testable hypotheses and points to potential opportunities for intervention and prevention. Directions for future research are discussed.
