Antisocial Process Screening Device

Paul J. Frick, Ph.D. 
Robert D. Hare, Ph.D.


The APSD is an instrument that detects antisocial characteristics and processes in young children (6 to 13 years) so that preventative measures can be taken at an early age. Early identification and intervention can prevent these tendencies from leading to crime and other destructive behaviors.Back to the top How to Use the Assessment
Parents and teachers rate the child on a dimensional scale that probes interpersonal, affective, and behavioral traits. The normative-based APSD–Combined form (APSD–C) allows you to integrate and reconcile responses from parents and teachers after they have completed the APSD–Parent (APSD–P) and the APSD–Teacher (APSD–T) forms. Each form takes approximately 10 minutes to complete.
