It has been long been noted as a hallmark of Obsessive Compulsive Disorder (OCD) that individuals have concerns over who they may be or are frightened of becoming. Yet, despite consensus that fears of self-concerns are implicated in the development and maintenance of OCD, research directly investigating a fear of self in OCD has been relatively scarce. More recently, however, due to advances in the measurement of these constructs, fear-of-self perceptions have been found to be strongly related to obsessive-compulsive symptoms. In addition, evidence is emerging that failures in introspection and lack of insight may be involved in how people with OCD reach false conclusions about themselves. Over the next four years, a total of 100 OCD patients, 60 anxiety patients, and 300 non-clinical participants will be recruited for a series of five different studies systematically investigating fear-of-self perceptions, introspective processes and insight in OCD.

These studies are aimed at improving the assessment of fear-of-self perceptions and introspective processes involved in self-knowledge, as well as determining the extent to which these processes are related to and specific to symptoms of OCD through experimental research. In addition, those with OCD will receive 24 weeks of specialized form of cognitive-behavioral therapy addressing self-themes that may underlie their symptoms. The key hypotheses are that fear of self perceptions and more limited introspective ability is characteristic of OCD, and that improvement in these processes successfully predicts treatment outcome. The research is expected to significantly contribute to the further development of specific treatment interventions in order to enhance the effectiveness of cognitive-behavior therapy.
