Background: Obsessive-compulsive disorder (OCD) and attention-deficit/hyperactivity disorder (ADHD) are two common neuropsychiatric conditions. Obsessive beliefs, comprising the importance and control of intrusive thoughts, inflated sense of responsibility for harm, overestimations of threat, perfectionism, and intolerance of uncertainty have been suggested to influence OCD symptomatology. Although OCD patients with ADHD have been reported to have different clinical characteristics compared to patients with OCD without ADHD, it has not been previously investigated whether OCD patients with and without ADHD differ in terms of obsessive beliefs. The aim of this study was to compare the obsessive beliefs and obsessive-compulsive symptoms of OCD patients with and without ADHD.
Methods: The study included a total of 197 OCD patients who were assessed with the sociodemographic data form, Wender Utah Rating Scale, Turgay’s Adult ADD/ADHD Diagnosis and Evaluation Scale, The Adult ADHD Self‐Report Scale, Obsessive Beliefs Questionnaire-44 (OBQ-44), Yale-Brown Obsessions and Compulsions Scale, Dimensional Obsessive-Compulsive Scale (DOCS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI).
Results: The scores of all subscales of OBQ-44, the responsibility, unacceptable thoughts, and symmetry subscales of DOCS, BDI, and BAI scores were higher in the OCD with ADHD group than in the OCD only group. The results showed that when depression and anxiety were controlled, “the importance and control of intrusive thoughts” domain of obsessive beliefs was the unique predictor of OCD and ADHD comorbidity.
Conclusion: These findings provide a better understanding of cognitive features in OCD patients with ADHD.
