Despite the steady decrease in violent crime over the past three decades, there has been an increase in targeted attacks toward people in public places, ranging from schools and workplaces to open recreational areas. Motivations vary, but often include both personal grievances and an attraction to extreme religious or political beliefs. Mental health professionals, on rare occasion, may find the antecedents of such thoughts, emotions, and behaviors in their patients. In this seminar, Dr. Meloy will teach such pre-offense warning behaviors to clinicians in attendance. Based upon his research group’s work over the past 15 years, and validated by numerous studies by others in North America, Europe, and Australia, these proximal warning behaviors provide important benchmarks for the clinician to identify, assess, and manage such threats posed by their patients in their daily practice.
