Update on Third Party Observers in Neuropsychological Evaluation: An Interorganizational Position Paper.

Objective: The National Academy of Neuropsychology (NAN), the American Academy of Clinical Neuropsychology (AACN), and the American College of Professional Neuropsychology (ACPN) collaborated to publish an update to their original position statements, confirming the organizations' opposition to third party observers (TPO).
Method: A review of literature addressing TPO effects, ethical standards, professional organization position statements, test publisher policies and new telemedicine developments was completed to obtain consensus on relevant issues in TPO and recording of neuropsychological evaluations.
Results: TPO has been shown to impact the cognitive functions most often assessed in forensic or medicolegal settings. Third party observation, whether in person, recorded or electronically, remains a potential threat to the validity and reliability of evaluation results, and violates test security guidelines, ethical principles and standards of conduct in the field. Demands for TPO in the context of medicolegal or forensic settings have become a tactic designed to limit the ability of the consulting neuropsychologist to perform assessment and provide information to the trier of fact.
Conclusions: The field of neuropsychology opposes the presence of TPO in the setting of medicolegal or forensic neuropsychological evaluations.
