Abstract: (66 Views)
Background: Obsessive–compulsive disorder is one of the most common psychiatric disorders and is listed among the top ten leading causes of disability worldwide. Due to its chronic and debilitating nature, relatively high prevalence, and its negative impact on various life domains, special clinical attention is needed. Accordingly, the present study aimed to investigate the relationship between temperament and character and obsessive–compulsive disorder, with a focus on the mediating role of self-regulation in patients diagnosed with obsessive–compulsive disorder.
Methods: This study employed a descriptive–correlational design based on structural equation modeling. The statistical population included all obsessive–compulsive disorder patients referring to public and private psychiatric clinics in Kermanshah. Based on inclusion and exclusion criteria, a confirmed obsessive–compulsive disorder diagnosis was obtained by a psychiatrist and a structured DSM-5 clinical interview. Three hundred eligible participants were selected using convenience sampling. Research instruments included the obsessive–compulsive inventory-revised, the self-regulation questionnaire, and the temperament and character inventory. Data were analyzed using descriptive statistics and structural equation modeling in SPSS 21 and PLS3.
Results: The hypothesized model demonstrated an acceptable fit (Normed Fit Index = 0.90; Standardized Root Mean Square Residual SRMR = 0.079). Temperament and character had a significant direct effect on self-regulation (t = 15.30). Additionally, temperament and character (t = 2.91) and self-regulation (t = 2.64) had significant direct effects on obsessive–compulsive disorder symptoms. Temperament and character also showed a significant indirect impact on obsessive–compulsive disorder through self-regulation (t = 2.54).
Conclusion: The findings highlight the importance of considering temperament, character traits, and self-regulatory capacities when designing psychological interventions for individuals with obsessive–compulsive disorder.
