Faller, K. C. (1998). The parental alienation syndrome: What is it and what data support it? Child Maltreatment, 3(2), 100-115. (PDF)
This article describes proposed characteristics and dynamics of PAS, and the methods used to document its presence. Research data related to various tenets of the syndrome are then reviewed. Dr. Faller notes that

"The parental alienation syndrome is a nondiagnostic syndrome. It is only useful for mental health professionals in explaining the symptom presentation if they know from other information that an abuse allegation is a deliberately made, false accusation. The syndrome cannot be used to decide whether the child has been sexually abused. As a consequence, it is of little probative value to courts in making decisions about the presence or absence of sexual abuse .... An additional problem with the parental alienation syndrome is that virtually every symptom described by Gardner as evidence of its presence, and consequent false charges against the accused parent, is open to opposing interpretations" (p. 111).

After reviewing the relevant research Faller concludes:

"No data are provided by Gardner to support the existence of the syndrome and its proposed dynamics. In fact, the research and clinical writing of other professionals leads to a conclusion that some of its tenets are wrong and that other tenets represent a minority view" (p. 112).
