In the eyes of their teachers, children diagnosed with Oppositional Defiant Disorder appear to be disrespectful, badly-behaved, difficult, inconsiderate, stubborn, and lacking in empathy. From a behaviour analytic perspective, we might describe the same behaviour as coercive, aversive, maladaptive but functional. We are trained to look for gaps in skill sets or awkward schedules of reinforcement. We are prepared to teach new skills and make adjustments to the environment, but we are less perhaps less comfortable approaching delicate topics like anxiety, impulsivity, reactivity, and trauma. Unfortunately, without acknowledging the emotional and cognitive differences of children diagnosed with Oppositional Defiant Disorder, our interventions can resemble the power struggles that children diagnosed with ODD are so familiar with. In this session, we will look at antagonism and trust through a behaviour analytic lens, and grapple with how to earn assent instead of simple compliance.
