Obsessive intrusive thoughts in nonclinical subjects. Part II. Cognitive appraisal, emotional response and thought control strategies

Abstract

This second part of the study reports on the appraisal and thought control responses of 270 students to their most upsetting intrusive thought. Multiple regression analysis revealed that belief that one could act on the intrusive thought and perceived uncontrollability of the thought were the two most important predictors of the frequency, or persistence of the distressing intrusion. Intrusions rated as very difficult to control were also associated with increased belief that one could act on the intrusion, avoidance of situations that may trigger the intrusion, reduced success with one's most typical thought control strategy and higher thought frequency. Based on the Padua Inventory Total score, high and low obsessional Ss were selected. Highly obsessional individuals reported more unwanted obsessive intrusive thoughts and rated their thoughts as significantly more frequent and believable than low obsessive individuals. The type of thought control strategy typically used was not a factor in thought frequency and controllability, nor did it differentiate between high and low obsessional groups. The results are discussed in terms of Salkovskis' cognitive model of obsessions and intrusive thoughts.
