Parent Management Training

Kazdin's PMT manual is the real thing — not a pop-psychology parenting book but one of the most rigorously validated behavioral interventions in child psychology, written by one of the field's leading figures and published by Oxford University Press. If you're a clinician, therapist, or a highly motivated parent dealing with oppositional or aggressive behavior in a child, this is where you go. It's dense, it's clinical, and it requires professional support to implement properly — but the evidence base behind it is unmatched.
