Adolescent parricide as a clinical and legal problem.

Criminologists contribute to the knowledge regarding the continuing problem of parricide by way of macrostudies, utilizing large samples that reveal patterns of how such acts are carried out, gender differences, and other aspects. Clinicians have the opportunity to pursue microinvestigations into the details of how cognitive processes and emotions operate in the adolescent who engages in such behavior. Such investigations entail pursuing specifics in the psychosocial realm, such as earlier maltreatments and ongoing psychological conflicts, and also being alert to the neurobiological differences between adolescents and adults. The use of battered child syndrome as a legal defense is discussed, with contrasts made between relying on a posttraumatic stress disorder (PTSD) approach and a duress defense, based on explanations related to shame and humiliation.
