The cognitive mediation of thought-control strategies.

Research suggests that people use various strategies to control their normally occurring intrusive thoughts. Strategies that involve worrying about the thought and self punishment appear to be associated with certain forms of psychopathology, such as obsessive-compulsive (OC) symptoms. The present study sought to examine whether dysfunctional beliefs associated with OC symptoms (e.g., beliefs that intrusive thoughts are highly significant) underlie the use of such thought control strategies. Ninety-three non-clinical participants completed self-report questionnaires measuring cognitive variables, thought-control strategies, and OC symptoms. Analyses revealed that overestimates of threat and responsibility, beliefs about the significance and need to control intrusions, the need for perfection and certainty, and scrupulosity were associated with the use of punishment, but not worry thought control strategies. These cognitive phenomena also mediated the relationship between OC symptoms and the use of punishment as a thought-control strategy. Results are discussed in terms of cognitive models of OC symptoms and their implications for cognitive-behavioral therapy.
