Relationship between insight level and clinical and familial features in pediatric obsessive-compulsive disorder.

Objective: The aim of this study was to explore the relationship between insight level and clinical and familial psychiatric features of children with obsessive-compulsive disorder (OCD).

Methods: Children's Yale-Brown Obsessive-Compulsive Scale-Symptom Checklist, 11^th item of the Children's Yale-Brown Obsessive-Compulsive Scale, Wechsler Intelligence Scale for Children Revised Form, Affective Disorders and Schizophrenia for School Aged Children Present and Lifetime Version 1.0, and Structured Diagnostic Interview for Diagnostic and Statistical Manual of Mental Disorders-IV Axis I Disorders were applied to 92 pediatric OCD patients.

Results: In this study, the prevalence of OCD in the first children of the family was high (41.3%), and low insight was significantly related with concomitant intellectual disability (p=0.003). The level of insight was high in patients with comorbid OCD spectrum disorders (p<0.001). Attention deficit and hyperactivity disorder (ADHD) was the most common psychiatric diagnosis accompanying OCD (19.5%). Among the obsession-compulsion subscales, the symmetry/hoarding was higher in males (p=0.046). OCD patients with a family history of major depressive disorder (MDD) had high ADHD comorbidity rates (p=0.038). In OCD patients, whose family had psychiatric disorders besides MDD and anxiety disorders, the diagnosis rate of intellectual disability was higher than other diagnoses (p<0.001).

Conclusion: The sociodemographic, clinical, and familial features of pediatric OCD patients cannot be adequately clarified if the patient has limited insight. Therefore, the insight of children with OCD should be considered a range or continuity.
