Parental Alienation – Science and Law explains the research that creates the foundation for the assessment, identification, and intervention in cases of parental alienation (PA). For attorneys, judges, and family law professionals, this book explains in detail the scientific basis for testimony and legal decisions that relate to PA. There are two complementary features for most of the chapters. First, the chapter authors address how evidence regarding PA meets the criteria of the Frye, Daubert, and Mohan cases as well as the Federal Rules of Evidence for testimony by experts. The second feature is to refute common misinformation. There is debate and disagreement about some aspects of PA theory. The editors of this book are concerned that some of the discourse regarding PA has spun out of control, into pervasive misinformation. This book provides plenty of evidence for overcoming that hurdle. The editors of this book and the chapter authors have extensive experience with both clinical and legal aspects of divorce, child custody, parenting time evaluations, PA, and related topics. The editors and chapter authors include six psychologists, three physicians, two social workers, four attorneys, and one judge. Collectively, these mental health professionals have testified as expert witnesses hundreds of times regarding family law topics. As an additional feature, the book contains four appendices and three indexes. Appendix A defines the concepts used in this book, so that the chapter authors and readers will use terminology in a consistent manner. Appendix B lists more than one thousand trial and appellate cases in the U.S. involving PA, organized by state. Appendix C presents twenty rather dramatic vignettes involving PA. Finally, Appendix D, “Sample Motion and Brief for Extended Voir Dire,” provides a motion and supporting brief asking the court to allow extended time to examine the competency of a proposed expert.
