Antisocial Process Screen Device, Self-Report Version
The self-report version of the Antisocial Process Screening Device (APSD-SR) is a copyright protected measure of several dimensions that have proven important for understanding antisocial behavior in children and adolescents: Callous-unemotional Traits, Narcissism, and Impulsivity. Researchers can download and use the APSD-SR free of charge in their work. My only request is that copies of any publications using the APSD-SR are sent to me at email@example.com.
There is no manual for the APSD-SR. Several studies which describe the development of the scale and initial tests of its validity can be obtained here.
