In his affidavits, as well as during nearly a full day of trial testimony, Dr. Geffner challenged the use of the MMPI and other psychological tests by Drs. Bernet and Walker. He stated that questions of domestic abuse and family violence implicated a specialized area of psychological practice which required a totally different testing regimen. He testified that he himself was an expert in the area of family violence and abuse, as shown by numerous publications he had authored and by his participation in professional societies that focus on those areas. These included the Natural Resource Center on Family Violence and Sexual Assault, an organization he had founded and in which served as president.
Dr. Geffner testified that none of the other psychiatrists or psychologists involved in this case possessed credentials similar to his, and he declared that the lack of such credentials rendered any opinions they might have as to the relative fitness of Father and Mother for parenting responsibilities suspect at best. He also stated that when a mental health professional conducts an evaluation outside that professionals expertise, it raises serious ethical issues. He accordingly recommended that Mother file ethics complaints with Vanderbilt and the State Licensing Boards against the other mental health professionals involved in the case.
