Objectives: Although an association has been found recently between obsessive-compulsive disorder and an increased risk of suicide, the prevalence of both suicidal ideation and attempts vary considerably and are generally assessed categorically. Our aims were to evaluate the prevalence of suicidal ideation and behaviors using a dimensional approach.Methods: The sample included 129 patients with obsessive-compulsive disorder. Suicidality was assessed by administering the Columbia-Suicide Severity Rating Scale. Logistic and linear regres-sions were used to examine predictors of suicidal ideation, severe suicidal ideation, and suicidal behavior.Results: The lifetime prevalence of suicidal ideation and behaviors were 64.3% and 16.3%, respectively. Lifetime suicidal ideation was associated with the number of stressful life events, duration of illness, Hamilton Rating Scale for Depression scores, and family history of mood disorders. A family history of obsessive-compulsive disorder was associated with a lower probability of lifetime suicidal ideation. Severe suicidal ideation was related to greater severity of the most stressful life event, Hamilton Rating Scale for Depression scores, and longer duration of untreated illness. The probability of lifetime suicidal behavior was related to Hamilton Rating Scale for Anxiety scores, symmetry obsessions, and washing and checking compulsions. The probability of lifetime non-suicidal self-injurious behaviors was related to Hamilton Rating Scale for Anxiety scores. Conclusions: Recognizing predictors of suicidal ideation/behavior is crucial to identifying patients at greater risk.

Abstract

Objectives: Although an association has been found recently between obsessive-compulsive disorder and an increased risk of suicide, the prevalence of both suicidal ideation and attempts vary considerably and are generally assessed categorically. Our aims were to evaluate the prevalence of suicidal ideation and behaviors using a dimensional approach.Methods: The sample included 129 patients with obsessive-compulsive disorder. Suicidality was assessed by administering the Columbia-Suicide Severity Rating Scale. Logistic and linear regres-sions were used to examine predictors of suicidal ideation, severe suicidal ideation, and suicidal behavior.Results: The lifetime prevalence of suicidal ideation and behaviors were 64.3% and 16.3%, respectively. Lifetime suicidal ideation was associated with the number of stressful life events, duration of illness, Hamilton Rating Scale for Depression scores, and family history of mood disorders. A family history of obsessive-compulsive disorder was associated with a lower probability of lifetime suicidal ideation. Severe suicidal ideation was related to greater severity of the most stressful life event, Hamilton Rating Scale for Depression scores, and longer duration of untreated illness. The probability of lifetime suicidal behavior was related to Hamilton Rating Scale for Anxiety scores, symmetry obsessions, and washing and checking compulsions. The probability of lifetime non-suicidal self-injurious behaviors was related to Hamilton Rating Scale for Anxiety scores. Conclusions: Recognizing predictors of suicidal ideation/behavior is crucial to identifying patients at greater risk.
