On Demand | Self-Paced Professional Training

This on-demand professional training program on Evidence for Mental Health Professionals is presented by David DeMatteo, PhD, ABPP in partnership with the American Board of Forensic Psychology (AAFP).

This on-demand professional training program focuses on evidence – expert reports and testimony – provided by mental health professionals in the context of criminal and civil legal proceedings. 

This program provides a concise legal primer, describes the history and current roles of experts in the U.S. justice system, and examines the admissibility standards for expert evidence provided by governing case law (e.g., Frye, Daubert, Kumho, Joiner) and various rules of evidence (e.g., Federal Rules of Evidence, Federal Rules of Civil Procedure, Federal Rules of Criminal Procedure). 

This program also covers other topics related to the provision of expert reports and testimony by mental health professionals in criminal and civil legal proceedings, including the various bases of expert testimony, the rule against hearsay, responding to subpoenas, ethics, and professionalism, the role of discovery, testifying to a “reasonable degree of scientific certainty,” strategies for providing testimony (direct-exam and cross-exam), and expert immunity. Best-practice standards for data gathering and data presentation are also discussed.

Upon completion of this training, participants will be able to:

  • 1 Describe the admissibility standards for expert evidence articulated by the Supreme Court of the United States
