Child Maltreatment, Parental Alienation, and the Science of Abuse

This memorandum provides an analysis of the critical definitions and research on child maltreatment, encompassing both child abuse and neglect, and its relationship to parental alienation. It outlines three widely recognized definitions of child maltreatment and highlights seven key peer-reviewed research studies. 

This memorandum also provides an analysis of the inter-relatedness of child maltreatment, child psychological abuse, and parental alienation. 

Together, these references illustrate the profound impact that child maltreatment — especially psychological and emotional abuse — has on children’s development and well-being.

The following information was first developed by Steven G. Miller, MD, a distinguished cardiologist, scientist, forensic evaluator, parental alienation specialist, mentor, colleague, and friend. 

Parental Alienation

Parental alienation (PA) is a specific form of psychological abuse in which one parent deliberately undermines and disrupts the child’s relationship with the other parent.

By fostering negative perceptions of the targeted parent, the alienating parent manipulates the child’s emotions, thoughts, and behaviors, often causing the child to unjustly reject the targeted parent. 

Parental Alienation and Psychological Maltreatment

This process is widely recognized as a form of child psychological maltreatment and is explicitly supported by the definitions of abuse provided by major psychiatric, child welfare, and public health authorities.

This document serves as a vital resource for attorneys, judges, clinicians, and forensic experts, offering a comprehensive understanding of the scientific foundations that support interventions in child maltreatment cases. 

The evidence presented here underscores the need for informed decision-making in legal and clinical contexts to better protect vulnerable children.

Recognizing parental alienation as a form of psychological maltreatment enables courts and child welfare agencies to take meaningful steps to protect children from ongoing harm, ensuring that children’s best interests remain a central focus in custody and visitation decisions.

Parental Alienation is Consistent With Definitions of Child Psychological and Emotional Abuse

Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) (American Psychiatric Association, 2013) – Child psychological abuse is defined as nonaccidental verbal or symbolic acts by a child’s parent or caregiver that result, or have the potential to result, in significant psychological harm to the child.

Examples of such acts include berating, humiliating, threatening, or confining a child. Parental alienation fits this definition as it involves deliberate acts to manipulate a child’s perception of the other parent, which can cause profound and lasting emotional harm.

American Professional Society on the Abuse of Children (APSAC) (Hart, Brassard, Baker, & Chiel, 2018).

Psychological maltreatment is defined as a repeated pattern or extreme incident(s) of caregiver behavior that thwarts a child’s basic psychological needs—including safety, socialization, and emotional support — and conveys to the child that they are worthless, unloved, or expendable.

Examples of APSAC’s Operational Definitions Relevant to Parental Alienation

These behaviors are often seen in parental alienation, where the alienating parent manipulates the child to believe the targeted parent is unsafe, unloving, or not worthy of a relationship.

U.S. Department of Health and Human Services (HHS) and Centers for Disease Control (CDC) and Prevention (Leeb et al., 2008).

Child maltreatment is defined as any act or series of acts of commission (child abuse) or omission (child neglect) by a parent or caregiver that results in harm, potential for harm, or threat of harm to a child.

These definitions collectively highlight the broader context of parental alienation as a form of child psychological maltreatment, emphasizing the impact of such behavior on children’s mental health, emotional stability, and relationships with both parents.

Research on Child Maltreatment, Psychological Abuse, and Adverse Childhood Experiences (ACEs)

The Adverse Childhood Experiences (ACEs) studies are a series of research studies that examine the relationship between childhood trauma and long-term health, well-being, and social outcomes.

Conducted initially by the CDC and Kaiser Permanente in the 1990s, the studies identified 10 key ACEs in categories like abuse, neglect, and household dysfunction (e.g., parental separation, substance abuse, mental illness, or incarceration).

The research revealed that higher exposure to ACEs is linked to increased risks of chronic diseases, mental health issues, substance abuse, and social challenges later in life.

The studies highlight the importance of early intervention and trauma-informed care to mitigate these negative outcomes.

This section presents seven key research studies that investigate the causes, consequences, and long-term effects of child maltreatment and adverse childhood experiences (ACEs). 

These studies establish a robust scientific framework for understanding the lasting impact of maltreatment on children’s physical, emotional, and cognitive development.

Felitti et al. (1998)

Relationship of Childhood Abuse and Household Dysfunction to Leading Causes of Death in Adults. This landmark ACE study, conducted by the CDC and Kaiser Permanente, involved over 9,500 adult participants. 

The study found that exposure to adverse childhood experiences (ACEs) significantly increases the risk of chronic diseases such as heart disease, lung disease, and cancer. 

The authors concluded that a “strong graded relationship” exists between ACE exposure and health risks, identifying ACEs as a key determinant of adult health and well-being.

Anda et al. (2006)

The Enduring Effects of Abuse and Related Adverse Experiences in Childhood. Based on data from over 17,000 participants in the ACE study, this research identified how child maltreatment affects brain development. 

The study revealed that childhood abuse alters brain structure and function, resulting in permanent behavioral and mental health issues.

It emphasized the link between adverse childhood experiences and the rewiring of brain circuits, which affects emotional regulation and cognitive development.

Edmiston et al. (2011)

Corticostriatal-Limbic Gray Matter Morphology in Adolescents with Exposure to Childhood Maltreatment. 

This study examined the structural brain changes caused by childhood maltreatment. Researchers found that maltreatment is associated with reduced gray matter volume in key areas of the adolescent brain. 

The loss of gray matter affects the regions responsible for decision-making, emotional regulation, and cognitive processing, thereby impairing emotional and cognitive abilities in affected children.

Spinazzola et al. (2014)

Unseen Wounds – The Contribution of Psychological Maltreatment to Child and Adolescent Mental Health.

This study of 5,616 youth demonstrated that psychological maltreatment’s impact on children is comparable to the effects of physical or sexual abuse.

It concluded that emotional abuse is as harmful to children as other forms of abuse, resulting in negative mental health outcomes, increased emotional instability, and long-term behavioral challenges.

Nurius et al. (2015)

Life Course Pathways of Adverse Childhood Experiences Toward Adult Psychological Well-Being. This study used a population-based survey of 13,593 individuals to identify the long-term effects of ACEs on mental health. 

The research found that ACEs significantly increase the likelihood of developing mental health issues in adulthood.

The study highlighted the importance of early intervention and preventive measures to reduce the lasting impacts of adverse experiences during childhood.

Taillieu et al. (2016)

Childhood Emotional Maltreatment and Mental Disorders. Analyzing data from 34,653 individuals, this study found that childhood emotional maltreatment increases the risk of developing mental illnesses and personality disorders later in life.

It emphasized the role of attachment theory, highlighting how emotional maltreatment disrupts the attachment bond, leading to long-term psychological harm and emotional instability.

Mitchell et al. (2017). Father Loss and Child Telomere Length

This study explored the biological impact of father loss (due to death, incarceration, or divorce) on child telomere length. Telomeres are protective caps on chromosomes that shorten due to stress and aging.

The study’s findings revealed that the absence of a father accelerates the shortening of telomeres, effectively “aging” a child’s cells at a molecular level.

This biological impact provides clear evidence of the physical harm caused by parental separation or alienation.

Conclusion

The definitions and research outlined in this memorandum demonstrate that child maltreatment — especially psychological and emotional abuse — has profound and far-reaching consequences on children’s brain development, physical health, and emotional well-being.

Scientific evidence underscores the seriousness of parental alienation as a distinct form of psychological abuse. 

Its impact can be as damaging as physical or sexual abuse, leading to significant developmental impairments that affect a child’s emotional, cognitive, and relational capacities. 

Courts, clinicians, and legal professionals have a critical role in mitigating the effects of parental alienation. 

Their interventions should be guided by a clear understanding of the scientific underpinnings of child maltreatment and its impact on child development. Early identification and intervention are essential to prevent the escalation of harm. 

Family courts must treat evidence of parental alienation as a serious consideration in custody and visitation cases, prioritizing the emotional and psychological well-being of the child. By formally acknowledging parental alienation as a form of child maltreatment, legal systems can more effectively address the root causes of emotional harm.

Finally, Child welfare agencies should establish protocols to recognize and address parental alienation early, thereby preventing irreversible psychological damage.
