The Relationship Between Juvenile Sex Offender Registration And Depression In Adulthood, Sharon E. Denniston

Walden Dissertations and Doctoral Studies

Accounts of sexual abuse appear daily in the media. Rightfully, this issue demands attention. Juveniles may be victims; they may also be offenders who are subject to sex offender registration and notification (SORN) policies. Growing research finds that SORN policies fail to achieve intended public policy outcomes. Little is known, however, about the unintended consequences of SORN for juvenile offenders. This study contributed to a more comprehensive understanding of the effects of these policies on this population. Merton's concept of manifest and latent functions of purposive social action and an alternate non-criminogenic form of Lemert's secondary deviance proposition provided the …
