Background and Aim: Obsessive-Compulsive Disorder (OCD) manifests as a different group of symptoms that include disturbing thoughts, obsessive-compulsive disorder, mental occupation and practical obsessions. These recurring practical or mental obsessions cause severe discomfort to the individual, as well as wasting time and significantly disrupting the normal course of life, job function, normal social activities, or relationships. Obsessive-compulsive disorder is a chronic disorder that has a profound effect on a person's life and social, emotional and occupational performance. Obsessive-compulsive disorder should perform its obsessive-compulsive behaviors to get rid of its thoughts, but this is a temporary relief. Not following the obsessive routine causes severe discomfort and anxiety. Therefore, recognizing obsessive-compulsive concerns seems necessary. In this study, standardization, validity and reliability of self-scale and obsessive-compulsive concerns have been investigated.
Methods: The method of this research was descriptive cross-sectional and validation. The statistical population of the study was students of Tehran universities in the academic year 1399-1398 as well as a number of clinical patients referred to counseling centers in Tehran who were diagnosed with obsessive-compulsive disorder and among these people, 323 Stepwise cluster random sampling method was selected as the research subjects. To evaluate the validity of the questionnaire, exploratory factor analysis by principal component analysis and Cronbach's alpha method were used to evaluate the reliability. Then, for the selected factors, the indicators of confirmatory factor analysis and internal consistency reliability coefficients were examined. All statistical analyzes were performed by SPSS software version 25.
Results: The findings of the factor analysis section showed that by factor analysis of questions and rotation of results by varimax method, three components are revealed, the number of these components obtained and also the questions with these components have a high factor load. Were largely consistent with the findings of the authors of the questionnaire. It was also found that both the whole questionnaire and all sub-tests have a high reliability coefficient. Findings of the study on the common values and factor load of the questionnaire items showed that the factor load of all items is high (from 0.44 to 0.78). By accepting the limit of 0.4 for factor loads, it is determined that the items of the questionnaire have an acceptable factor load (above 0.4). This finding indicates that based on factor analysis, the existence of these items is important for the questionnaire and has appropriate validity; Therefore, the questionnaire has the appropriate construct validity. The results of confirmatory factor analysis showed that the three-factor model obtained from exploratory factor analysis in the Iranian population has a relatively good fit. According to the value of fitness indicators (GFI), adjusted fit goodness index (AGFI), adaptive fit index (CFI), the three-factor model shows a good fit. The results of Cronbach's alpha coefficients showed that the Persian version of its scale and obsessive worries have a very high internal consistency. This means that the items on this scale have the necessary homogeneity. In addition, Cronbach's alpha was 0.94 for the whole questionnaire, 0.89 for aggregation of values or hoarding, 0.91 for ethics, and 0.85 for others. . In this case, it can be said that each of the items is measuring the same structure and no conceptual dispersion is seen in them.
Conclusion: The findings of this study showed that this questionnaire is a suitable diagnostic tool to identify the level of obsessive-compulsive disorder in adults.
