Applying the SDM and D-SDM to Antisocial Personality, Psychopathy, and "Sociopathy"

This clinical guide operationalizes the Scretching Diagnostic Matrix (SDM) and Dynamic Scretching Diagnostic Matrix (D-SDM) for assessing adults presenting with persistent antisocial behavior, possible Antisocial Personality Disorder (ASPD), psychopathic traits, or sociopathic characteristics. The framework distinguishes formal DSM-5-TR diagnosis from dimensional personality traits, descriptive behavioral phenotypes, diagnostic validity, acute safety, longitudinal risk, comorbidity, and treatment response. ASPD is treated as the formal diagnosis, psychopathy as a dimensional specialist construct, and sociopathy as a descriptive term rather than an independent psychiatric diagnosis. The guide provides a structured approach to differential diagnosis, longitudinal assessment, clinical decision-making, and treatment monitoring.
