title: Cognitive intrusions in a non-clinical population. I. Response style, subjective experience, and appraisal.
abstract: The present study identified distinctive response styles to unpleasant cognitive intrusions to further understanding of intrusive phenomena similar to those observed in obsessive-compulsive disorder and other anxiety disorders. Response styles were studied among 125 university students who completed a questionnaire describing and evaluating seven cognitive intrusions and inventories of depressive, anxious, and compulsive symptoms. Almost all subjects (99%) reported intrusions and 92% included effortful strategies in response to intrusions in their repertoire. Large differences were observed in the dominant strategy used. Three distinctive dominant response styles were identified including no effortful response (26%) and two effortful styles, attentive thinking (34%), and escape/avoidance (40%). The two groups using effortful strategies were more anxious and reported more difficulty removing intrusions. The group using escape/avoidance strategies reported more sadness, worry, guilt, and disapproval than subjects reporting no effortful response. The attentive thinking group reported more varied forms and more frequently triggered intrusions then the no effortful response group. Within subject analyses support the group comparisons and showed that intrusions eliciting escape/avoidance strategies were evaluated more disapprovingly than thoughts eliciting attentive thinking. The results are discussed in terms of Salkovskis' (Behavior Research and Therapy, 27, 677-682, 1985) formulation of obsessive-compulsive disorder and Borkovec's (Journal of Consulting and Clinical Psychology, 23, 481-482, 1985) and Barlow's (Anxiety and its disorders: The nature and treatment of anxiety and panic, 1988) discussions of worry and generalized anxiety.
