What the evidence shows
What does the research say about parental alienation?
Is parental alienation recognised as harmful?
The psychological and medical communities have moved — slowly, but measurably — toward recognising parental alienation as a real phenomenon with serious effects on children. The American Psychological Association, the American Bar Association, and family court systems in multiple jurisdictions now acknowledge it, even if their responses vary widely. A 2018 meta-review of 213 empirical studies across 10 languages confirmed that parental alienation is a form of family violence (Harman, Kruk & Hines, 2018).

Research by Amy Baker and others documents the long-term effects on children who were alienated from a parent: higher rates of depression, anxiety, low self-esteem, difficulty forming trusting relationships, and — in many cases — eventual regret and grief when they understand what happened. 82% of adults alienated as children struggled with intimate relationships (Baker, 2007). This is why fighting for your relationship with your child is not futile: it matters for their future, not only yours.

If parental alienation affects even 11% of high-conflict divorces — a conservative estimate — and there are hundreds of thousands of such divorces per year in English-speaking countries alone, the number of affected parents runs into the millions. The isolation you feel is a result of stigma, legal confidentiality, and the shame that is imposed on alienated parents — not of rarity. The most robust data comes from Harman et al. (2019) showing 22 million parents in the U.S. and Canada are targeted, and Hine (2025) finding 39-60% of separated UK parents experience alienating behaviours.
Do family courts recognise parental alienation?
Family courts in most jurisdictions are not well-equipped to identify or respond to parental alienation. Judges, CAFCASS officers, and court-appointed therapists vary enormously in their understanding. A 2022 review in Developmental Psychology found nearly 1,200 courts between 1985 and 2018 agreed evidence of parental alienation was relevant and admissible. This is why having a clear, evidence-based account of what is happening — and why — is so important if you are engaged in legal proceedings.

Prevalence of Parental Alienation (U.S. & Canada)
Harman, Leder-Elder & Kruk (2019). Children and Youth Services Review.
Approximately 13.4% of parents report being targets of alienating behaviours — over 22 million parents in the U.S. alone. The most robust population-level prevalence data available.
Read the full study →Alienating Behaviours in Separated Parents (UK)
Hine, B. (2025). Journal of Family Violence.
A UK national survey of 1,005 parents found 39.2% experienced alienating behaviours. Cross-referenced with Baker's criteria, that figure jumped to nearly 60%. Common — but extremely hard to detect externally.
Read the full study →Parental Alienation as Family Violence
Harman, Kruk & Hines (2018). Psychological Bulletin, 144(12).
Scientifically validated that alienation fits the exact profile of Intimate Partner Violence — a form of coercive control involving isolation, gaslighting, and economic abuse through the children.
Read the full study →Parent–Child Estrangement & Reunion (U.S.)
Reczek, Stacey & Thomeer (2022). Journal of Marriage and Family.
Tracked 8,000+ adult children longitudinally. 26% experienced estrangement from their father. The critical finding: 69–81% eventually reunited. Reconciliation is the norm, not the exception.

Baker, A. J. L. (2005/2007). Adult Children of Parental Alienation Syndrome. W.W. Norton.
82% struggled with intimate relationships in adulthood, alongside higher rates of depression, anxiety, substance abuse, and identity confusion. Many experienced regret and sought to reconnect.
View Baker's research →Construct Validity & Mental Health Impact (Nordic)
Meland, A., et al. (2024). SAGE Journals.
Confirmed the construct validity of parental alienation and established dose-response links — the more alienating behaviours present, the greater the measurable psychological harm to parents and children.

Arránz Becker & Hank (2022). Journal of Marriage and Family.
A ten-year longitudinal study of 10,228 adult children. 20% estranged from father, 9% from mother. Estrangement patterns are consistent across cultures — this is a global phenomenon.

Harman, J. J., et al. (2018–2022). Colorado State University.
Up to 23% of targeted parents reported suicide attempts or severe suicidal ideation. This is not a custody inconvenience — it is a life-threatening psychological crisis.

Frequently asked questions
How common is parental alienation?
Parental alienation is far more common than most people realise. A 2019 U.S. population study found 13.4% of parents — over 22 million — report being targets of alienating behaviours (Harman, Leder-Elder & Kruk, 2019). A 2025 UK survey found 39-60% of separated parents experience alienating behaviours (Hine, 2025). An estimated 3.8 million children in the U.S. are moderately to severely alienated from a parent.
Is parental alienation recognised as a form of abuse?
Yes. A 2018 meta-review in Psychological Bulletin, covering 213 empirical studies across 10 languages, scientifically validated that parental alienation fits the exact profile of Intimate Partner Violence — a form of coercive control involving isolation, gaslighting, and economic abuse through the children (Harman, Kruk & Hines, 2018).
Do alienated children eventually reunite with the alienated parent?
Research strongly suggests yes. A longitudinal study tracking 8,000+ adult children found that 69-81% who experienced estrangement from a parent eventually reunited (Reczek, Stacey & Thomeer, 2022). Reconciliation is the norm, not the exception.
What are the long-term effects of parental alienation on children?
Research by Amy Baker found that 82% of adults who were alienated as children struggled with intimate relationships, alongside higher rates of depression, anxiety, substance abuse, and identity confusion. Many experienced regret and eventually sought to reconnect with the alienated parent (Baker, 2007). Read more about the parental alienation trauma model.
Do family courts recognise parental alienation?
Recognition varies widely by jurisdiction. The American Psychological Association and the American Bar Association acknowledge parental alienation as a real phenomenon, and a 2022 review in Developmental Psychology found nearly 1,200 trial and appellate courts between 1985 and 2018 agreed that evidence of possible parental alienation was relevant and admissible. However, many individual judges and court-appointed professionals still lack training in identifying it.
