The Drama Triangle is a social model that was conceived by Stephen Karpman, M.D., a student studying under Eric Berne, M.D., the father of transactional analysis.
Through popular usage and the work of Karpman and others, Karpman's triangle has been adapted for use in structural analysis (defining the conflict roles of persecutor, victim, and rescuer) and transactional analysis (diagramming how participants switch roles in conflict) [REF].
