Parental alienation is a form of child abuse that we are only beginning to recognize. Technically speaking, it’s when a child aligns with one parent and rejects its other parent for reasons that are not warranted. According to The Parental Alienation Study Group, at least 3.9 million children in the United States are “moderately to severely” alienated from a parent. Put another way, there are three times as many children in the United States who are alienated from a parent than there are children with autism .

This is, obviously, a staggering number. But what are the effects of parental alienation on children? This was the question of a study conducted by psychologists Caitlin Bentley and Mandy Matthewson of the University of Tasmania.

In order to pursue this inquiry, they recruited adult participants who had a history of parental alienation. From there, they conducted semi-structured interviews, asking a series of exploratory questions about the alienation. Their narratives were then analyzed for themes.

The results were striking. Seven themes were identified, revealing the breadth and depth of the effects of alienation well into adulthood. A selective overview of the study’s findings is provided below.
