Why do these sources matter?
Parental alienation is sometimes dismissed as a "theory" or an "unproven concept." The research collected here tells a different story. Across developmental psychology, attachment theory, family law, trauma studies, and coercive control literature, a consistent picture emerges: parental alienation is a well-documented pattern of psychological harm that affects millions of families worldwide.
These sources underpin every claim on Love Over Exile. They inform the signs and symptoms we describe, the survival strategies we recommend, the effects on children we document, and the healing frameworks we offer. If you are a targeted parent trying to explain your situation to a therapist, lawyer, or judge, this page gives you the evidence base to do so.
How do you use this page?
Each entry has a short summary of what the source contributes to the Love Over Exile framework, and a direct link to the primary source — PubMed, DOI, publisher, or the author's institutional page. Entries marked core are cited in multiple places on the site.
If a statistic, model, or quote appears anywhere on Love Over Exile and you want to check its source, it will be on this page. If you believe a source is missing, outdated, or misattributed, contact Malcolm.

Frequently Asked Questions
Is parental alienation supported by research?
Yes. A 2018 review in Psychological Bulletin by Harman, Kruk and Hines classified parental alienating behaviours as a form of family violence — specifically child psychological abuse and intimate partner violence. A 2022 follow-up review in Developmental Psychology (Harman, Warshak, Lorandos & Florian) assessed the full empirical base of 213 studies across 10 languages and confirmed the scientific status of parental alienation as a well-researched phenomenon. The statistics page summarises the key findings.
What does the research say about reunification rates?
Research on reunification is still emerging. Studies suggest that early intervention, consistent contact attempts by the targeted parent, and court-ordered therapeutic interventions improve outcomes. However, severe alienation cases — where the child has fully internalised the rejection — are significantly harder to reverse. The staying connected guide covers practical strategies based on this research.
How many studies exist on parental alienation?
The Parental Alienation Study Group (PASG) maintains the world's largest curated index of peer-reviewed PA research. The Harman, Warshak, Lorandos & Florian (2022) scientific-status review in Developmental Psychology surveyed 213 empirical studies across 10 languages, with 40% published since 2016. The broader research base spans developmental psychology, family law, attachment theory, trauma studies, and coercive control literature.
Is parental alienation recognised by the WHO?
The ICD-11, published by the World Health Organisation, includes the classification QE52.0 — Caregiver-Child Relationship Problem — which covers relational problems with caregivers. While it does not use the term "parental alienation" directly, this classification is referenced in clinical PA assessments worldwide. See our PA Syndrome page for more context.
What is the Five-Factor Model for diagnosing parental alienation?
The Five-Factor Model, developed by Bernet et al. (2020), is the current diagnostic gold standard. It requires: (1) the child refuses contact with a parent, (2) a previously positive relationship existed, (3) there is no evidence of abuse by the targeted parent, (4) the favoured parent has engaged in alienating behaviours, and (5) the child displays characteristic behavioural manifestations. All five factors must be present. Learn more on the signs of PA page.
