Practical Guidelines and Recommendations for Improving the Preparation of Psychological Expert Reports Within the Spanish Legal Framework

Abstract The forensic psychological report is a key element in communication between the expert and legal professionals, serving as a critical piece of evidence in the administration of justice. Its preparation involves technical and ethical challenges, particularly due to insufficient legal regulation and limited empirical research. Through a narrative review of the literature, this paper synthesizes practical guidelines to improve both formal and substantive aspects of forensic psychological reports in Spain. It identifies common errors, proposes an organizational model, and offers key strategies for writing, to enhance the report’s clarity and evidentiary value.
