Temporal stability of obsessive-compulsive symptom dimensions in an undergraduate sample - A prospective 2-year follow-up study

The temporal stability of obsessive-compulsive symptom dimensions was studied in a nonclinical student sample. The Obsessive-Compulsive InventoryRevised was administered twice to 132 undergraduate students during a 2-year period. There were no significant changes in symptom dimension scores between the baseline and follow-up, except for the Obsessing scale. The score of each dimension at follow-up was strongly and uniquely predicted from the score on the same dimension at baseline. The results indicate that obsessivecompulsive symptom dimensions tend to be temporally stable in nonclinical participants, replicating similar studies in clinical populations.
