The Social Problem Solving Inventory of Revised and Intolerance of Uncertainty Scale were administered to patients who met DSM-IV criteria for patients with obsessive-compulsive disorder (n = 43), patients with post-traumatic stress disorder (n = 41) and patients with panic disorder (39) and 79 non-patients. A one way Multivariate Analysis of Covariance (MANCOVA) with group (OCD, PTSD, PD and non-patient), the 5 SPSI-R scale, was performed, revealed a significant main effect for group (p<0.001).One follow-up univariate analysis of covariance, controlling for intolerance of uncertainty was conducted for each SPSI-R scale. The results showed that patients with of OCD, PTSD and PD would score higher than non-patient group on scales of negative problem orientation, impulsivity/carelessness style and avoidance style and score lower than non-patients on scales of positive problem orientation style and rational problem solving. These findings suggest that social problem solving may be a core feature of anxiety disorders. Keywords: Social problem-solving;intolerance of uncertainty;anxiety disorders
