The Relationship between Performance of Attention Task andSuicidal Ideation in Korean Patients with Mood Disorders

ABSTRACT

Objective@#We examined the performance of attention tests related to suicidal ideation in mood disorder patients and to explain the differenceof attention test performance in relation to suicidal ideation after controlling clinical and psychological variables of mood disorderpatients. @*Methods@#Seventy-three in- and outpatients with major depressive disorder (n=41) or bipolar disorder (n=32) completed a self-ratingquestionnaire assessing socio-demographic characteristics, and clinical and psychological variables. Comprehensive Attention Test(CAT) also was conducted. @*Results@#Thirty-three patients were the high-suicidal ideation (SI) group, and forty patients were the low-SI group. The errors of commission(CEs) of visual sustained attention in the high-SI group was 6.3 times higher on average than that of the low-SI group. Aftercontrolling for sex, age, and diagnosis, a higher number of CEs on visual sustained attention tasks predicted higher SI score. However,after controlling for sex, age, diagnosis, and depressive mood, this predictive ability was no longer observed. @*Conclusion@#This study showed that CE on the visual sustained attention task seems to influence suicidal ideation as a result of interactionwith depressive symptoms.
