Profile / Research Interests
Dr. Frederick Aardema studied clinical psychology at the University of Groningen and the University of Amsterdam in the Netherlands. Frederick Aardema pioneered the development of a new questionnaire that reliably measured a characteristic reasoning style in those with obsessive-compulsive and delusional disorder – The Inferential Confusion Questionnaire. In addition, his work in reasoning led to the development of an innovative theoretical approach to pure obsessional ruminations (Aardema and O’Connor, 2003, 2007). Dr. Frederick Aardema has published widely in international journals in the field of obsessive-compulsive and related disorders, and is a frequent presenter at scientific conferences. In particular, his research interests include psychometric and experimental methods in the measurement of reasoning processes in OCD, as well as the application of inference and narrative based models to obsessions without overt compulsions. Other aspects of his research include dissociation, virtual reality, introspective ability, self-constructs and psychological assessment.

Current Projects
A recent research project involves the role of confabulatory introspection and insight in non-clinical populations. Specifically, the overlap between Obsessive-Compulsive Disorder and Delusional Disorder has been a matter of debate for some time, leading some to suggest that OCD might be better conceptualized as a schizotypal disorder rather than an anxiety disorder. Both disorders are characterized by faulty beliefs about reality which cause a considerable degree of distress and behavioral problems. In particular, a critical mass of studies has shown that failures in introspection are 1) dramatic, 2) at the root of what appears to be insight, and 3) measurable in an experimental reasoning task (Johansson et al, 2005). The application of this experimental paradigm to clinical disorders is expected to have a considerable impact as it could resolve the long-standing question as to why and how people arrive at false beliefs about reality – a central topic in cognitive-behavioural formulations of clinical disorders.
