Dr. Tana Dineen completed her Ph.D. in 1975 and, since 1977, has been a licensed clinical psychologist and a member of both CPA and APA.
Her early research focused on how belief systems can contaminate the thinking of mental health professionals. She has maintained this interest (and concern) throughout her wide-ranging career during which she moved from university teaching to become the first (and, to date, the only) non-medical treatment director in a large Canadian psychiatric hospital and later established a private practice which she closed in 1993 to return to research and writing.
Her controversial book 'Manufacturing Victims: What the Psychology Industry is Doing to People,' first released in 1996 and now in a 3rd, completely revised, 2001 edition, describes psychology as 'big business and examines how it operates like an industry complete with business formulas, marketing strategies and periodic re-tooling to meet changing consumer demands.
