Dr. Alyse Price-Tobler's groundbreaking research delves into the challenges faced by adult-child survivors of severe parental alienation (SPA) resulting from intense custody conflicts. This study highlights the lack of understanding among mental health practitioners regarding child psychological abuse and high conflict divorce, emphasizing the need for targeted professional development and evidence-based treatment protocols. Volume One of the twin PhD study provides a comprehensive examination of SPA's impact on survivors and practitioners, setting the stage for further insights. The research also uncovers a potential new specific phobia variant among SPA survivors who have experienced factitious disorder imposed on another (FDIOA) and child abduction. Furthermore, the study explores potential correlations between SPA and autoimmune diseases and cancers, opening doors for future research into the complex relationship between SPA and mental and physical health. A practitioner-focused study results of the twin PhD thesis will be presented in Volume Two
