Previous studies have not thoroughly explored whether impulsivity in OCD patients is a result of the obsessive-compulsive symptoms themselves or other contributing factors. This study aimed to explore whether cognitive emotion regulation strategies and depressive symptoms mediate the relationship between the severity of obsessive-compulsive symptoms and impulsivity in a clinical population with OCD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a case-control study that recruited 65 OCD patients (male\/female=31\/34) and 65 healthy controls (male\/female =23\/42), matched for age, gender, and education level. Demographic and clinical data were collected, and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Beck Depression Inventory-II (BDI-II), Barratt Impulsiveness Scale-11 (BIS-11) and Cognitive Emotion Regulation Questionnaire (CERQ) were adopted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      OCD patients scored higher on BIS-11 attentional and non-planning impulsiveness and total scores (all\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&amp;lt;\u00a00.05). On CERQ, OCD patients showed elevated maladaptive strategies (self-blame, rumination, catastrophizing, blaming others) and reduced adaptive strategies (positive reappraisal) (all\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&amp;lt;\u00a00.05).

After adjusting for age, gender, depression level, there was only a significant negative correlation between BIS-11 non-planning impulsiveness and CERQ maladaptive strategies (\n                      <jats:italic>r<\/jats:italic>\n                      \u00a0=\u00a0-0.28,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&amp;lt;\u00a00.05).
