Externalizing problems, internalizing problems, and suicidal ideation in Singaporean adolescents: Sex differences

Adolescent suicide is considered a worldwide problem and an increasing source of concern in Singapore. This study explores the relationships among four factors of maladjustment (that is, emotional distress, negative self, antisocial behavior, and anger control problems) and suicidal ideation in two hundred and seventy-one adolescents from Singapore. Findings from the study indicated that emotional distress, negative self-concept, and antisocial behavior significantly predicted suicidal ideation for the whole sample. Beta weight is largest for emotional distress, followed by negative self, and then antisocial behavior. For females, only emotional distress significantly predicted suicidal ideation. For males, only negative self-concept significantly predicted suicidal ideation. Implications of these findings with regard to working with adolescents with suicidal ideations are discussed.
