The role of meta-memory and meta-cognition in obsessive–compulsive disorder (OCD) symptoms and checking was examined in a student sample, using the memory and cognitive confidence scale (MACCS; Nedeljkovic, M., & Kyrios, M. (2007). Confidence in memory and other cognitive processes in obsessive-compulsive disorder. Behaviour Research and Therapy, 45, 2899–2914). Confirmatory factor analysis supported the MACCS's previously reported structure, and hierarchical regression supported its relationship to OCD symptom severity over-and-above depression and other OCD-related beliefs. Specifically, general confidence in memory was found to be a unique predictor of overall OCD severity. Implications for theory and research are discussed.
