How they work
PCIT
Core mechanism: Live-coached parent-child interaction reshapes attachment quality and behavioral contingencies simultaneously
Ontology: Child behavior problems maintained by coercive parent-child interaction cycles and insecure attachment
Triple P
Core mechanism: Graduated parent skill-building at appropriate intensity level; minimal sufficiency principle uses least intervention necessary
Ontology: Child behavior problems primarily maintained by parenting patterns and family environment; population-level prevention possible

What each assumes — and misses
PCIT
Philosophical roots: Bowlby (attachment); Patterson (coercion theory); Baumrind (authoritative parenting); Ainsworth (responsive caregiving)
Blind spots: Narrow age range (2-7); requires live coaching setup; less applicable to adolescents or complex family configurations
Therapeutic voice: Tell him exactly what you see him doing right now. 'I like the way you're sharing those blocks.'
Triple P
Philosophical roots: Patterson (coercion theory); Bandura (social learning); Sanders (population approach); public health model; Bronfenbrenner (ecological, minimal sufficiency)
Blind spots: Population-level approach may miss individual complexity; culturally normed parenting standards may not translate universally
Therapeutic voice: When he acts out, get down to his level, make eye contact, and give one clear instruction.
Choosing between them
PCIT and Triple P both sit within the Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
