Abstract：This study selected ninety⁃nine outpatients and inpatients with obsessive⁃compulsive disorder
（OCD）in Nanjing Brain Hospital for two longitudinal follow⁃up surveys with an interval of 3 months to explore
the relationship between absolute belief，catastrophizing beliefs and obsessive⁃compulsive symptoms and their
interactions. We adopted the Yale⁃Brown Obsessive⁃Compulsive Scale（Y⁃BOCS）to measure the severity of
obsessive⁃compulsive symptoms; the Absolute Belief Scale and Catastrophic Belief Scale to assess the level of
beliefs; and the Obsessive ⁃ Compulsive Belief Questionnaire（OBQ） to measure obsessive ⁃ compulsive beliefs.
Bootstrap results revealed that catastrophizing beliefs fully mediated between absolutizing beliefs and obsessive⁃
compulsive symptoms in patients diagnosed with OCD，with a mediating effect size of 0.02 （95% CI: 0.01~
0.03）. The cross ⁃ lagged regression showed that the absolute beliefs related to others in the pretest had a
significant predictive effect on both self⁃evaluation（β=0.238，P<0.05）and others’evaluation（β=0.278，P<0.05）
of catastrophizing beliefs in the posttest. In conclusion，catastrophizing beliefs of OCD patients may fully
mediate between absolutizing beliefs and obsessive ⁃ compulsive symptoms. The others related factor in
absolutizing beliefs predicts the belief levels of both self⁃ and others⁃rated factors in catastrophizing beliefs.
