title: Longitudinal aspects of obsessive compulsive cognitions in a non-clinical sample: a five-year follow-up study.
abstract: The cognitive behavioural models of Obsessive Compulsive Disorder (OCD) have stressed the role of cognitions, not only in aetiology but also in maintenance of the disorder. Little is known about the temporal relations between obsessive-compulsive cognitions and OCD symptoms. The aim of this study was to carry out a prospective assessment of OCD related beliefs and symptoms in a non-clinical sample. A total of 99 university students completed the Obsessive Beliefs Questionnaire (OBQ), Padua Inventory (PI), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Worry Domain Questionnaire (WDQ) one, three and five years after baseline administration. Structural modelling predicting scores at later time periods and growth curve modelling were used to analyze the data. The results showed that obsessive-compulsive cognitions varied significantly over time. It was also found that the OBQ predicted symptom scales (Impaired Mental Control, Contamination and Checking) only at baseline. However symptom scores remained stable at each time point, as shown by the subscales of Impaired Mental Control, Contamination and Checking of the PI and the BAI, BDI and WDQ. Implications for future research and the cognitive model of OCD are discussed.
