Based on previous results the cognitive profile of patients with obsessive-compulsive disorder (OCD) is determined by the impairment of executive and visual-spatial memory functions. The Rey-Osterrieth Complex Figure (ROCF) is a widely used tool for examining visual-spatial memory disorders. Several scoring systems can be used to evaluate the ROCF and the most widespread is the original Osterrieth evaluation system. The Boston Qualitative Scoring System (BQSS) is a new, much more detailed scoring system than the Osterrieth, which allows both quantitative and a more detailed qualitative analysis of ROCF. In our study, we analyzed the copying and immediate recall performance of 24 OCD and 24 age- and education-matched healthy control subjects using the Osterrieth and BQSS scoring systems. Our research had two main goals, (1) to examine the diff erences in visualspatial memory performance shown by the OCD group compared to the control group, and (2) to compare the Osterrieth and BQSS scoring systems in one clinical sample. Based on both the Osterrieth and BQSS scoring systems, our results show that the OCD group performed significantly worse in the recall phase, but not in the copy phase. According to our results both scoring systems can be effectively used to examine the functioning of visual-spatial memory in OCD patients. While the Osterrieth evaluation system is faster and more widespread, the BQSS scoring system examines detailed qualitative aspects in addition to quantitative indicators.
