What we know — and what it means
Parental alienation is 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.

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. 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 legal system is behind
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. 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.
The research
Key studies used in the book
The claims in Love Over Exile are grounded in peer-reviewed research. These are the major studies that underpin the book.
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.

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.

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.
Read the full study →Parent–Child Estrangement (German Family Panel)
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.
Read the full study →Suicide Risk Among Targeted Parents
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.
