The present study examined associations among dimensions of suicidality and psychopathology in a sample of 428 homeless adolescents (56.3% female). Confirmatory factor analysis results provided support for a three-factor model in which suicidality (measured with lifetime suicidal ideation and suicide attempts), internalizing disorders (assessed with lifetime diagnoses of major depressive episode and post-traumatic stress disorder), and externalizing disorders (indicated by lifetime diagnoses of conduct disorder, alcohol abuse, and drug abuse) were positively intercorrelated. The findings illustrate the utility of a dimensional approach that integrates suicidality and psychopathology into one model.
本研究在428名无家可归青少年样本(56.3%为女性)中检验了自杀倾向维度与精神病理学之间的关联。验证性因素分析结果支持了一个三因素模型,其中自杀倾向(用终生自杀意念和自杀未遂来衡量)、内化障碍(用终生重度抑郁发作和创伤后应激障碍诊断来评估)和外化障碍(用终生品行障碍、酒精滥用和药物滥用诊断来表明)呈正相关。这些发现说明了一种将自杀倾向和精神病理学整合到一个模型中的维度方法的实用性。
