The existence of the Parental Alienation Syndrome is not scientifically validated. Besides scientific articles demonstrating this, there are explicit declarations of scientific societies: “The American Psychological Association believes that all mental health practitioners as well as law enforcement officials and the courts must take any reports of domestic violence in divorce and child custody cases seriously. An APA 1996 Presidential Task Force on Violence and the Family noted the lack of data to support so-called “parental alienation syndrome”, and raised concern about the term’s use. However, we have no official position on the purported syndrome.”. Moreover, it states that “The syndrome has been dismissed by the American Psychiatric Association, American Psychological Association, and American Medical Association as lacking supporting empirical or clinical evidence and it is not included in the Diagnostic and Statistical Manual of Mental Disorders or the International Classification of Diseases”
