Parental Alienation: What the Research Actually Says

A child who once loved one parent now refuses contact. The other
parent says it is the child's choice. The targeted parent has been
told the same thing by lawyers, by therapists, and sometimes by
family.

What the targeted parent is looking for, often at midnight after
another silent weekend, is a name for what is happening, and a way
to tell whether what they suspect is real.

Public conversation about parental alienation will give them two
answers, and neither is what the research shows. One register
dismisses parental alienation as junk science, a discredited
concept weaponized in custody court. Another insists alienation is
everywhere, that any child who refuses contact has been turned.

Parental alienation is a documented
harm to children — measurable in clinical instruments, replicated
across decades and across countries, and gender-symmetric in who
does it and who is targeted by it. What follows is what the
research actually says, where the unsettled questions sit, and
how the alienation literature itself separates alienation from
estrangement.

What is parental alienation?

Parental alienation is a pattern of behavior in which one parent
denigrates, undermines, or actively obstructs a child's
relationship with the other fit parent, without justified cause.
Researchers including Baker, Bernet, Harman, and their
collaborators have documented the pattern across decades and across
countries.

The behavioral foundation is laid out in Harman, Kruk, and Hines
(2018), a Psychological Bulletin review that synthesizes the
literature and proposes a behavioral classification: direct
strategies and indirect strategies, behaviors against the child
and behaviors against the targeted parent. The authors frame the
behaviors as a form of family violence, their framing rather than
the field's settled consensus. The behavioral findings themselves
are not contested by it.

The strategies are concrete. Baker and Darnall (2006) surveyed
ninety-seven targeted parents and identified the recurring
behaviors that became the canonical seventeen-strategy list still
used in research and clinical assessment today. They include
badmouthing the other parent to the child; limiting contact and
interfering with calls, texts, and mail; telling the child the
other parent does not love them; forcing the child to choose
between parents; and asking the child to keep secrets from the
other parent. A mother whose ex-husband tells their daughter that
her father has abandoned them is doing the same thing as a father
whose ex-wife tells their son that his mother only wants him for
child support. The pattern, not the parent, is what the research
describes.

The behavior also leaves a measurable signature in children.
Bernet, Gregory, Reay, and Rohner (2018) showed that severely
alienated children display extreme splitting on the Parental
Acceptance–Rejection Questionnaire, idealizing one parent and
devaluing the other at magnitudes far beyond what is seen in
children of divorce generally. That measurement work matters
because it gives clinicians a way to distinguish the pattern from
ordinary post-divorce ambivalence. Children of divorce who are
not being alienated do not split this way.

What does the research show about effects on children?

Children exposed to sustained alienating behavior show measurable
harms: attachment disruption, identity confusion, anxiety and
depression symptoms, and intergenerational transmission of
relationship dysfunction in retrospective adult-child studies. The
findings are consistent across the empirical literature, with
methodological caveats noted below.

Among the most carefully designed studies in this literature is
Verrocchio, Marchetti, Carrozzino, Compare, and Fulcheri (2019),
which surveyed 296 Italian adults and found that recalled
childhood exposure to alienating behaviors predicted adult
depression and reduced health-related quality of life after
statistically controlling for inter-parental conflict. That
control matters: the most common objection to alienation research
is that what looks like alienation is really just high-conflict
divorce. Verrocchio and colleagues addressed the objection
head-on and found the association held independently. The Italian
community sample is also a methodological strength because it is
not drawn from clinical referrals or online self-selection, which
is the dominant source for most retrospective work in this field.

The pattern replicates internationally. Verrocchio, Baker, and
Bernet (2016) found similar associations in a larger Italian
community sample of more than 600 adults. Baker and Ben-Ami (2011)
found alienation-strategy exposure predicted lower self-esteem
and higher depression in a US online sample of 118 adults,
partially mediated by insecure attachment to the targeted parent.
Ben-Ami and Baker (2012) extended this in a 106-adult sample to
long-term correlates including substance use, lower
self-sufficiency, and insecure adult attachment styles. Bentley
and Matthewson (2020) interviewed twenty Australian adults who
had been alienated as children and identified themes of grief,
identity disruption, mistrust in close relationships, and
difficulty parenting their own children. Miralles, Godoy, and
Hidalgo (2021) synthesized the broader literature and concluded
that exposure to alienating behaviors in childhood is consistently
associated with depression, anxiety, insecure attachment, and
lower self-esteem in adulthood.

These findings rest on retrospective evidence. Adults are
recalling their childhoods, often years later, and most samples
are either self-selected online or drawn from clinical referrals.
The field acknowledges this. What gives the body of work its
evidentiary weight is replication. The same patterns appear in
independent samples drawn from different countries, by different
research teams, using different instruments. When that kind of
consistency holds across methodologically heterogeneous studies,
the underlying phenomenon is doing the work, not any single
study's design.

Baker (2005), the foundational qualitative interview study of
forty adult children of alienation, also identified themes the
field is still investigating. A subset of her interviewees
described later becoming estranged from their own children,
suggesting an intergenerational pattern, though others described
deliberately breaking it. The evidence base for true
intergenerational transmission is qualitative and the literature
is just beginning to examine it; it is a hypothesis, not a
finding.

How is parental alienation measured?

Researchers use validated instruments to assess alienating
behaviors and their effects, including Baker's Strategies
Questionnaire, Bernet's Five-Factor Model, and the Rowlands
Parental Alienating Behaviors Scale. None is treated as definitive
on its own; clinicians use them as part of a multi-method
assessment.

Baker's Parental Alienation Strategies Questionnaire is the
parent-report (or adult-child-report) instrument that catalogs the
seventeen behavioral strategies introduced earlier. Baker and
Darnall (2006) is the development paper for the strategies
framework; subsequent research by Baker and colleagues has applied
the instrument across multiple samples. The strategies
questionnaire is widely used in research and clinical practice,
but is best understood as a behavioral inventory rather than a
diagnostic tool. It measures what is being done, not whether a
particular case meets a clinical threshold.

Bernet's Five-Factor Model is the clinician-applied diagnostic
framework widely cited in the forensic literature. Bernet and
Greenhill (2022) is the formal Journal of the American Academy
of Child and Adolescent Psychiatry statement of the model.
Briefly, the five factors are: the child actively avoids or
refuses a relationship with one parent; a prior positive
relationship existed; there is an absence of abuse, neglect, or
seriously deficient parenting on the part of the rejected parent;
the favored parent has used multiple alienating behaviors; and
the child exhibits the behavioral manifestations of alienation
that the research literature has documented. Factor 3 — the
absence of abuse, neglect, or seriously deficient parenting — is
the operationalization of the alienation-versus-estrangement
distinction, and this article returns to it in the next section.

The Rowlands Parental Alienating Behaviors Scale (PABS) is a
newer instrument designed for clinician and observer use in
forensic and custody-evaluation contexts. Rowlands (2019)
develops it. PABS and the Baker Strategies Questionnaire are
treated in the literature as complementary rather than competing:
Baker measures the behavioral repertoire from the targeted
parent's vantage, PABS measures the same construct from the
evaluator's vantage. A qualified forensic clinician working a
case may use both, along with the Parental Acceptance–Rejection
Questionnaire splitting analysis from Bernet and colleagues, and
alongside collateral interviews and observation.

The behaviors are measurable. Whether parental alienation should
be classified as a unified diagnostic syndrome is a separate
question, taken up later in this article.

Alienation versus estrangement: what is the difference?

The alienation literature itself draws a sharp line between
alienation — a child's rejection of a fit parent without
justified cause — and estrangement, a child's rejection of a
parent grounded in that parent's actual conduct toward the
child. Bernet and Baker both treat this distinction as essential
to a credible assessment.

The stakes are clinical and they cut both ways. Children refuse
contact with parents for many reasons. Some of those reasons are
alienation. Some are not. Failing to tell the difference harms
children either way: by labeling justified refusal as alienation
and forcing contact with a parent who has actually harmed the
child, or by labeling alienation as the child's autonomous choice
and leaving an alienating dynamic uninterrupted. A serious
treatment of either pattern requires telling them apart.

The framework custody evaluators use was articulated by Drozd and
Olesen (2004) in the Journal of Child Custody. Their
decision-tree paper distinguishes alienation, justified
estrangement, and hybrid cases: situations where both alienating
behavior by one parent and justified rejection of the other are
present together. The hybrid category is important. Family-court
professionals see it frequently, and it is the category
single-cause framings on either side of the public conversation
tend to miss.

The distinction is also built into the diagnostic model itself.
Bernet's Five-Factor Model, Factor 3, requires the absence of
abuse, neglect, or seriously deficient parenting on the part of
the rejected parent. If that factor is not satisfied, the case
is not alienation by the definition the literature uses. This is
not a political concession from outside the field; it is the
field's own operational threshold. A custody evaluator following
the Bernet model who finds substantiated abuse by the rejected
parent does not diagnose alienation. They diagnose what the
evidence shows.

Friedlander and Walters (2010), writing in Family Court
Review, extended the framework to intervention selection. Their
argument is that the pattern determines the response: approaches
that help a child in an alienation case can harm a child in an
estrangement case, and the reverse. That has practical
implications this article will not unpack in depth. The
reunification-approach spectrum is its own topic. The point here
is that the distinction matters operationally, not just
academically.

None of this makes the assessment easy in any specific case.
Trained forensic clinicians who do this work for a living
describe hybrid cases in particular as genuinely ambiguous,
requiring multiple sources of evidence and time to sort. The
article does not claim the distinction is easy in practice. It
claims the distinction is real, the literature treats it as
essential, and the people qualified to make it are forensic
clinicians working with adequate evidence — not parents working
alone, not opposing attorneys, and not lay family members.

A father whose daughter refuses contact may be a target of
alienation, may be estranged for cause, or may be in a hybrid
case. A mother whose son refuses contact may be a target of
alienation, may be estranged for cause, or may be in a hybrid
case. The clinical question is the same; the answer depends on
the facts of the case, not the parent's gender.

Is parental alienation a diagnosis?

Parental alienation as a standalone diagnostic syndrome is not
in the DSM-5. It was considered and declined for inclusion. The
DSM-5 does include adjacent codes, notably V61.29 / Z62.898,
Child Affected by Parental Relationship Distress, that capture
much of the same clinical territory. The behavioral pattern is
documented independently of the diagnostic-category question.

The chronology is worth getting right because secondary sources
often get it wrong. Before the DSM-5's 2013 publication, the
task force considered submissions urging inclusion of a
standalone "Parental Alienation Disorder" diagnosis and declined
to add it. The task force added "Child Affected by Parental
Relationship Distress" (CAPRD), code V61.29 (ICD-9-CM) and
Z62.898 (ICD-10-CM), which captures the clinical territory under
a relational-problem code. Bernet, Wamboldt, and Narrow (2016) —
three authors directly involved in the DSM-5 process — describe
CAPRD in the Journal of the American Academy of Child and
Adolescent Psychiatry as the diagnostic home for the relational
pattern. DSM-5-TR (2022) carried CAPRD forward unchanged.

The ICD-11 chronology is also commonly misreported. The accurate
sequence: during ICD-11 development, "parental alienation" was
briefly added as an index/synonym term under the existing code
QE52.0, "Caregiver-child relationship problem." In February
2020, that index term was removed. The underlying code remained
throughout. The World Health Organization's stated reasoning,
published on its ICD-11 Frequently Asked Questions page, is that
parental alienation "is not a health care term" but is "rather
used in legal contexts, generally in the context of custody
disputes in divorce or other partnership dissolution," and that
"there are no evidence-based health care interventions
specifically for parental alienation." The ICD-11 did not add
then remove a code for parental alienation. It added then
removed an index term for behaviors already covered by an
existing relational code.

The peer-reviewed critique of the diagnostic-syndrome construct
is a small body of work, narrowly scoped. Faller (1998), writing
in Child Maltreatment, argued that Gardner's original Parental
Alienation Syndrome lacked empirical support and that the
proposed symptom set was derived from clinical impression rather
than validated data. Pepiton, Alvis, Allen, and Logid (2012)
wrote a direct rebuttal to the DSM-5-era inclusion push, arguing
that the proposed diagnosis did not meet the standards of
scientific evidence required for a diagnostic manual. Houchin,
Ranseen, Hash, and Bartnicki (2012), writing in the Journal of
the American Academy of Psychiatry and the Law, argued that the
DSM is the wrong forum for resolving what is fundamentally a
custody-litigation question. Each of these critiques targets the
diagnostic construct. None argues that alienating behaviors do
not occur or that children are not harmed by them.

The clearest empirical synthesis is Saini, Johnston, Fidler, and
Bala (2016), whose chapter in the Oxford University Press volume
Parenting Plan Evaluations (second edition) reviews the
empirical literature and concludes that it supports the existence
of the behavioral pattern but does not support a settled
unified-syndrome construct of the kind Gardner proposed. That
is, in the field's own language, the calibrated position: real
phenomenon, unsettled diagnostic category.

The institutional posture varies. The Association of Family and
Conciliation Courts (AFCC), in its 2022 joint statement with the
National Council of Juvenile and Family Court Judges, treats
parent-child contact problems — the umbrella term it uses for
alienation, estrangement, and hybrid cases together — as
multi-causal and requiring multi-method assessment. The American
Psychological Association has been more cautious. Its 1996
Presidential Task Force on Violence and the Family flagged
concerns about how PAS was being deployed in custody litigation,
and a brief 2008 press statement said the APA has "no official
position on the purported syndrome." That sentence, "no official
position," is what the APA itself says, not a characterization
of it.

The diagnostic-category question is unsettled in a way the
behavioral question is not.

Does the gender of the alienating parent matter?

Alienating parents are mothers and fathers in roughly comparable
numbers in the research. The residential or primary-custodial
parent has greater opportunity to engage in alienating behavior
by structure — a different statement from a claim about which
gender does it more, which this publication declines to make.

Harman, Leder-Elder, and Biringen (2019) drew on three nationally
representative US polls to estimate that roughly 35 to 45 percent
of separated or divorced adults report experiencing some
alienating behaviors. The 2019 data, and earlier work by the same
team (Harman, Leder-Elder, & Biringen, 2016), show
targeted-parent gender ratios roughly comparable across mothers
and fathers in nationally representative samples.

Some forensic-sample studies report higher rates of mothers as
alienating parents than the nationally representative polls do —
Bernet and Greenhill (2022) cite one such sample in which roughly
seven of every ten alienating parents in a forensic referral set
were mothers. The methodologically careful reading is that this
finding is confounded by the residential-parent base rate. In
2018, about 80 percent of the roughly 13 million custodial
parents in the United States were mothers (Grall, 2020, US Census
Bureau), and the residential parent has structurally more
opportunity for alienating behavior because the residential
parent spends more time with the child. That is a fact about
custody allocation patterns, not a claim about who alienates by
disposition.

This publication takes no position on which gender alienates
more often, because the question is not the publication's
concern. The targeted parent in front of you is the targeted
parent in front of you. If she is a mother, the literature
applies. If he is a father, the literature applies. The clinical
pattern is what is being measured, not the demographic of who is
doing it. What harms the child is the pattern; the parent's
gender is not the variable that matters.

What this means in practice for the targeted parent

The research supports three practical takeaways: alienation is
real and harmful to children; the alienation-estrangement
distinction matters and should be assessed by a qualified
clinician; documenting alienating behaviors over time strengthens
both clinical and forensic responses.

Documentation matters. Contemporaneous notes — written when an
incident happened, not reconstructed months later — carry more
weight in both clinical assessment and family-court contexts than
retrospective recall does. How to Document Co-Parenting Issues (Without Making It Worse) treats what good documentation actually looks like in practice — the four criteria, what to record, what to skip, and which tools fit which situations.

Qualified clinical assessment matters. The
alienation-versus-estrangement distinction is genuinely hard. The
literature is clear that this is not an assessment a parent
should attempt on their own, that an opposing attorney is the
wrong arbiter, and that a layperson family member, however
well-intentioned, is not qualified. Forensic clinicians with
training in custody evaluation are. A separate planned article
will treat the reunification-approach spectrum, where the same
care about qualifications applies.

The constitutional dimension is also real. The parent-child
relationship is constitutionally protected — Troxel v.
Granville, Stanley v. Illinois, Lehr v. Robertson — and a
state-tolerated severance of that relationship by something
other than parental unfitness is a structural harm, not just a
private one. This publication's constitutional cornerstone
develops that argument in depth.

This article is the recognition piece. The tactical pieces in
the pillar — on documentation, on response strategies, on the
reunification-approach spectrum — are the next reads. The point
of the recognition piece is to make sure the reader has the
vocabulary and the calibrated frame the rest of the pillar
depends on.

Parental alienation is real. It harms children. The behavioral
pattern is documented in instruments validated across countries
and decades, the effects on children are replicated in
independent samples, and the clinical distinction between
alienation and estrangement is built into the diagnostic models
the field actually uses. The diagnostic-syndrome question
remains unsettled, and this article reports that faithfully. The
unsettled question is narrower than the public conversation
makes it, and it does not unsettle what the behavioral research
shows.

This article is written for any parent of any gender who is
experiencing this, and for any professional working with such a
parent. The publication's editorial stance is the
calibrated-affirmative one Saini and colleagues describe: the
behaviors are real, the harms are real, and the people best
positioned to make case-specific determinations are qualified
forensic clinicians with adequate evidence.

This article is for general educational and advocacy purposes
only. It is not legal or clinical advice. Parents facing custody
issues, or who suspect alienation or estrangement in their
family, should consult a qualified attorney and a qualified
forensic clinical professional in their jurisdiction.

Frequently asked questions

What is parental alienation?

Parental alienation is a pattern of behavior in which one parent
denigrates, undermines, or actively obstructs a child's
relationship with the other fit parent, without justified cause.
Researchers including Baker, Bernet, Harman, and their
collaborators have documented the pattern across decades and
across countries. The behavior is measurable; the validated
instruments include Baker's Strategies Questionnaire and Bernet's
Five-Factor Model.

Is parental alienation real?

Yes. The behavioral pattern is documented in peer-reviewed
research across the United States, Italy, Australia, and other
countries, and the effects on children are replicated across
multiple samples. The separate question of whether parental
alienation should be classified as a unified diagnostic syndrome
is contested in the formal psychiatric literature, but that is a
different question from whether the phenomenon is real, which it
is.

Is parental alienation in the DSM-5?

Parental Alienation Disorder is not in the DSM-5 as a standalone
diagnosis. The DSM-5 task force considered it and declined to add
it. The DSM-5 does include V61.29 / Z62.898, "Child Affected by
Parental Relationship Distress" (CAPRD), which captures much of
the same clinical territory under a relational-problem code.
DSM-5-TR (2022) carried CAPRD forward unchanged.

What is the difference between parental alienation and estrangement?

The alienation literature itself draws this line. Alienation is
a child's rejection of a fit parent without justified cause,
often with contribution from the other parent. Estrangement is a
child's rejection of a parent grounded in that parent's actual
conduct toward the child. Bernet's Five-Factor Model Factor 3
operationalizes the distinction; Drozd and Olesen's 2004 paper
"Is it abuse, alienation, and/or estrangement? A decision tree"
is the canonical custody-evaluation framework.

What does the research show about effects on children?

Children exposed to sustained alienating behavior show measurable
harms: attachment disruption, anxiety and depression symptoms,
identity confusion, and in retrospective adult-child studies,
intergenerational transmission of relationship dysfunction. The
findings replicate across US, Italian, and Australian samples.
Most of the literature is retrospective, which the field
acknowledges and which makes cross-sample replication especially
important.

Do mothers or fathers alienate more often?

In nationally representative US polls, targeted-parent gender
ratios are roughly comparable. Forensic-sample studies sometimes
report higher rates of mothers as alienating parents, but this is
confounded by the residential-parent base rate, since the
residential parent has structurally more opportunity to engage
in alienating behavior. This publication takes no position on
which gender alienates more often.

How is parental alienation measured?

With validated instruments. Baker's Parental Alienation Strategies
Questionnaire enumerates seventeen behavioral strategies.
Bernet's Five-Factor Model is a clinician-applied diagnostic
framework. The Rowlands Parental Alienating Behaviors Scale is a
clinician / observer instrument designed for forensic use. None
is definitive alone; qualified clinicians use them as part of a
multi-method assessment.

What should a parent do if they suspect alienation?

Three things the research supports. First, take the
alienation-estrangement distinction seriously and seek a qualified
forensic clinical assessment rather than diagnosing the situation
alone. Second, document specific alienating behaviors over time;
contemporaneous notes have more weight than later recall. Third,
treat this article as the recognition step; tactical guidance on
documentation and response is its own topic in the pillar.
