The study sample included 84 adolescents with OCD according to DSM-5. The participants completed materials of Obsessive Compulsive Inventory-Child Version (OCI-CV), Children Depression Questionnaire (CDQ), Children’s Yale-Brown Obsessive Compulsive Scale-Severity Rating (CY-BOCS-SR), and Child Assessment of Belief Scale (CABS). Data were analyzed through descriptive statistics’ indices, Pearson correlation, separation coefficient, and multi-variant regression, using SPSS.<br> <strong>Findings:</strong> There was a strong positive relationship between the hoarding dimension and delusional insight. Also, severity, ordering, and doubting/checking were significantly correlated with insight, while this result disappeared by controlling the hoarding dimension via partial correlation. Moreover, adolescents with more symptoms of hoarding demonstrated a significantly higher score in OCI-CV, severity and delusional insight but not in the depression inventory.<br> <strong>Conclusion:</strong> Findings of the present study consistent with prior findings suggest a non-significant relationship between OCD clinical dimensions and insight in adolescents.</div> Obsessive-Compulsive Disorder, Severity, Insight, Depression 157 162 http://hehp.modares.ac.ir/browse.php?a_code=A-5-10332-2&slc_lang=en&sid=4 S.
