Introduction: In recent studies, deficit in cognitive process has been investigated as one of the etiological hypotheses in a wide range of Obsessive-Compulsive Disorder (OCD). This research aimed to compare cognitive process in patients with OCD and healthy groups., Methods: In the current cross-sectional analytic study, 43 patients with OCD and 43 healthy individuals matched with gender, age, educational and marital status were selected by convenience sampling method and assessed by Wisconsin Cart Sorting Test (WCST), Paced Auditory Serial Addition Test (PASAT) and Yale-Brown Obsessive Compulsive Scale (Y-BOCS). The obtained data were analyzed with Chi-square, Independent t test, Mann-Whitney U test and Pearson correlation in SPSS version16., Results: There was no difference between the patients with OCD and the healthy group in demographic characteristics (P>0.05). There was a significant differences between two group on the all subscale of WCST test and PASAT3, PASAT2 tests (P<0.01). These findings indicate that the OCD patient's performance in cognitive process was significantly worse than the healthy controls., Conclusion: The findings indicate that individuals with OCD suffer from a deficiency in various aspects of cognitive processes. Therefore, paying attention to these deficiencies can make an important contribution to the treatment of these patients., Competing Interests: Conflict of interest The authors declared no conflict of interest.

The quality of life (QOL) has been defined as ''a person's sense of well-being that stems from satisfaction or dissatisfaction with the areas of life that are important to him/her''. Age was also significantly associated with several functional limitations such as illness, and physical restrictions. The concept of ''resilience'' refers to successful adaptation that unfolds within a context of significant and usually debilitating adversity or life stress. The ability to adapt to pain may play an important role in maintaining the QOL. In this study, we investigated the role of resilience and age in various domains of quality of life such as physical, psychological, social and environmental domains. In this study, 290 adult patients (146 men, 144 women) completed the Connor-Davidson Resilience Scale and the WHOQOL-BREF questionnaire. Moreover, we illustrated several demographic variables. The results were analyzed using SPSS version 19.0 and means, descriptive correlation and regression were calculated. Our data revealed that resilience and age could significantly anticipate the QOL and physical aspect (P<0.001). In psychological, social and environmental domains resilience but not the age could significantly predict this domains. In addition, it is noticeable that the effect of resilience on the prediction of QOL is much more obvious in the psychological domain.. In conclusion, resilience is more important factor than the age in prediction of life quality (QOL) in persons suffering from chronic pain.

The quality of life (QOL) has been defined as "a person's sense of well-being that stems from satisfaction or dissatisfaction with the areas of life that are important to him/her". It is generally accepted that pain intensity and duration have a negative impact on the QOL. One specific type of control is "self-efficacy", or the belief that one has the ability to successfully engage in specific actions. The ability to adapt to pain may play an important role in maintaining the QOL. In this study, we investigated the role of self-efficacy, pain intensity, and pain duration in various domains of quality of life such as physical, psychological, social and environmental domains. In this study, 290 adult patients (146 men, 144 women) completed coping self-efficacy and the WHOQOL-BREF Questionnaire. Moreover, we illustrated numerical rating scale for pain intensity. The results were analyzed using SPSS version of 19.0 and means, descriptive correlation, and regression were calculated. Our data revealed that self-efficacy but not the pain duration could significantly anticipate the QOL and its four related domains (P<0.001). In addition, it is noticeable that the effect of self-efficacy on the prediction of QOL is much more obvious in the psychological domain. However, the pain intensity could predict all of the QOL domains (P<0.001) except social and environmental ones. In conclusion, to predict the quality of life (QOL) in person suffering from chronic pain, self-efficacy and pain intensity are more important factors than the pain duration and demographic variables.
