Forensic psychologists play a critical and complex role when assessing claims of parental alienation, in which one parent creates irrationally strong negative feelings from the child toward the other parent, within child custody and access evaluations. These evaluations are essential for forming an accurate understanding of family dynamics, distinguishing parental alienation from other forms of parental rejection, and ultimately developing effective, child-centered intervention strategies. Given the contentious nature and potential for profound psychological harm involved in these cases, forensic assessment requires a robust, neutral, and systematic approach.
