Frequency and correlates of suicidal ideation in pediatric obsessive-compulsive disorder.

This study examined the frequency and sociodemographic and clinical correlates of suicidal ideation in a sample of children and adolescents with obsessive-compulsive disorder (OCD). Fifty-four youth with OCD and their parent(s) were administered the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime, Children's Yale-Brown Obsessive Compulsive Scale, and Children's Depression Rating Scale-Revised. Children completed the Suicidal Ideation Questionnaire-Junior (SIQ-JR), Child Obsessive Compulsive Impact Scale-Child, and Multidimensional Anxiety Scale for Children; parents completed the Child Obsessive Compulsive Impact Scale-Parent, Swanson, Nolan, and Pelham-IV Parent Scale, and Young Mania Rating Scale-Parent Version. Seven youth endorsed clinically significant levels of suicidal ideation on the SIQ-JR. Suicidal ideation was significantly related to clinician-rated depressive symptoms, age, child-rated impairment and anxiety symptoms, and symmetry, sexuality/religiosity and miscellaneous symptom dimensions. There was no significant association between suicidal ideation and obsessive-compulsive symptom severity, comorbidity patterns, or several parent-rated indices (e.g., impairment, impulsivity). These results provide initial information regarding the frequency and correlates of suicidal ideation in treatment-seeking youth with OCD. Clinical implications are discussed, as well as directions for future research.
