Adjudicated adolescents (i.e., teens who have committed criminal offenses and are incarcerated in juvenile detention centers) have deficits in emotion regulation, including empathy skills, and are at risk for a host of poor outcomes including repeat offenses, internalizing symptoms (e.g., depression, anxiety), externalizing symptoms (e.g., lying, truancy, fighting). Many of these problems stem from a lack of secure attachment to parents and peers. There is a need for novel and innovative programs to help these teens develop more secure attachments and better empathy skills to prevent poor outcomes. One type of intervention is animal-assisted interventions such as dog training programs. These programs appear to build empathy skills in at-risk youth, which may translate into better peer relations, less psychological distress, and less recidivism. The goal of this study is to test an existing animal-assisted intervention program that is already being used in juvenile detention centers to determine whether it is efficacious in improving adjudicated adolescents' empathy skills and psychological symptoms through building a secure attachment to the training dog.
