Coercive Family Process

Patterson's foundational monograph laying out the coercive cycle: aversive child behaviour + parental capitulation = mutual negative reinforcement, escalating into chronic conduct problems. Empirical backbone of Oregon Social Learning Center's Parent Management Training-Oregon (PMTO) protocol. Cited by virtually every modern parent-training program for conduct problems (Triple-P, IY, PCIT, KEEP). The original "behavioural parent training" theory.
