Parental Alienation — Diagnostic Criteria (Bernet's 5 + Baker's 8 + Fidler & Bala's 4)

TL;DR. The current international diagnostic framework for parental alienation is a 3-layer convergence: Bernet's 5 essential criteria (all must be present) · Baker's 8 child behavioral indicators (the canonical signs) · Fidler & Bala's 4 differential markers (PA vs. justified estrangement). Anchored in DSM-5 V995.51, WHO ICD-11 QE52, and the Harman/Kruk/Hines (2018) family-violence framing.

Layer 1 — Bernet's 5 essential criteria

All 5 must be present:

  1. Child actively rejects a previously loved parent
  2. Rejection is disproportionate to anything that parent has done
  3. Child is exposed to alienating behaviors by the favored parent
  4. Child exhibits Baker's 8 behavioral indicators (Layer 2)
  5. There is no justified estrangement (abuse, neglect, profound mismatch)

Layer 2 — Baker's 8 behavioral indicators

  1. Campaign of denigration
  2. Weak / frivolous / borrowed reasons for rejection
  3. Lack of ambivalence (parent split into all-good/all-bad)
  4. "Independent thinker" phenomenon
  5. Reflexive support of the alienating parent
  6. Absence of guilt over cruel treatment
  7. Borrowed scenarios (events the child couldn't have witnessed)
  8. Spread of animosity to the targeted parent's extended family — highest-confidence signal

Layer 3 — Fidler & Bala's 4 differential markers

Dimension Alienation Justified estrangement
Proportionality Disproportionate Proportional
Ambivalence All-or-nothing Ambivalent
Language Adult-borrowed Developmentally appropriate
Scope Spreads to extended family Usually scoped to parent
