Abstract
Background & Objective: Obsessive–Compulsive Disorder (OCD) manifests as a group of symptoms, including disturbing thoughts, obsessive–compulsive disorder, mental occupation, and practical obsessions. These recurring practical or mental obsessions cause severe discomfort to the individual, waste time, and significantly disrupt the normal course of life, job function, regular 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. OCD patients should perform their obsessive–compulsive behaviors to get rid of their 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, psychometrics, validity, and reliability of self–questionnaire obsessive–compulsive concerns are investigated.
Methods: In terms of purpose, this research was an instrument development and a methodological study. The statistical population of the study comprised students at Tehran universities in the academic year 2019–2020 and several clinical patients referred to counseling centers in Tehran who were diagnosed with OCD. Among these people, 323 subjects were selected by stepwise cluster random sampling. To evaluate the reliability of the self–questionnaire and obsessive concerns (García–Soriano G et al., 2012), we examined the internal consistency and for the validity, the content and face validities. The confirmatory factor analysis was used to assess the factor construct (construct validity) and convergent validity (correlation with Beck depression and Beck anxiety and obsessive thoughts questionnaires). The discriminative validity was used to compare the mean score of OCD patients with the healthy group. All statistical analyses were performed using SPSS software version 25.
Results: The factor construct of self–questionnaire and obsessive concerns was not rejected in the Iranian sample. The fit indices were as follows: TFL=0.891, CFI= 0.901, NFI=0.94, IFI, 0.904, RMSEA=0.056. The Cronbach alpha values were 0.94 for the whole questionnaire, 0.89 for compulsive hoarding, 0.91 for maintaining ethical values, and 0.85 for responsibility toward others. The content validity was assessed using the opinions of psychology experts about the items, and the content validity ratio was checked for every question, which was between 0.8 and 1. Also, the correlation coefficients of three dimensions of the questionnaire (compulsive hoarding, maintaining ethical values, and responsibility toward others) were 0.40, 0.11, and 0.13 with the Beck depression inventory, 0.43, 0.14, and 0.15 with the Beck anxiety questionnaire, and 0.67, 0.53, and 0.42 with obsessive beliefs, respectively. To determine the discriminative validity, the research instrument items were compared between the normal group (212 people) and clinical people with OCD (110 people) using multifactorial and 1–factor analysis of variance of three factors: compulsive hoarding, maintaining ethical values, and responsibility toward others. The results of the multifactorial analysis of variance showed significant differences between the two groups regarding dependent variables (F=5.786, p<0.05, Ƞ²=0.052).
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.
