How they work
Filial Therapy
Core mechanism: Training parents in child-centered play therapy skills transforms the parent-child relationship from the inside — the parent becomes the healing agent in the child's natural environment
Ontology: Children's emotional problems are relational at root; the most powerful intervention is changing the relational environment by changing how the parent responds
Play Therapy
Core mechanism: Play as the child's natural language enables expression, mastery, and processing of experiences that words cannot reach
Ontology: Children's distress is expressed through play, not verbal insight; play is the developmental medium for processing

What each assumes — and misses
Filial Therapy
Philosophical roots: Rogers (unconditional positive regard applied to parenting); Axline (child-centered play therapy); Guerney (relationship enhancement); attachment theory
Blind spots: Requires motivated parents; not appropriate when parent is the source of harm; less structured than PCIT (harder to train); assumes parent has 30 min/week for home sessions
Therapeutic voice: In these special play times, your only job is to follow Marcus's lead and reflect what you see. No questions, no teaching, no directing.
Play Therapy
Philosophical roots: Piaget (play as cognitive development); Vygotsky (play as zone of proximal development); Winnicott (transitional space, playing); Axline (child-centered approach via Rogers); Klein (play as child's free association)
Blind spots: Evidence base is modest; age-limited; transition to verbal therapy can be poorly managed
Therapeutic voice: [Following the child's lead in play] The bear is going somewhere safe? Tell me about that safe place.
Choosing between them
Filial Therapy and Play Therapy both sit within the Humanistic 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.
