To examine longitudinal associations between community violence exposure and suicide ideation and attempt, and whether depressive symptoms and aggressive behavior are intervening variables in this association.
Participants were 473 urban and predominantly African American adolescents who completed measures of community violence exposure, depressive symptoms, and suicide ideation and attempt in grades 6, 7, and 8; teachers reported about adolescents' aggressive behaviors in grades 6, 7, and 8. Path analysis was used to examine direct and indirect associations between community violence exposure in grade 6 and suicide ideation and attempt in grade 8. Depressive symptoms and aggressive behavior were examined as part of an indirect path from grade 6 community violence exposure to later suicide ideation and attempt.
Results revealed an indirect association between community violence exposure and later suicide ideation for males and females; community violence exposure in grade 6 was associated with depressive symptoms in grade 7, which in turn, were positively associated with suicide ideation in grade 8. For males, community violence exposure in grade 6 was associated with increases in aggressive behavior in grade 7, which in turn, were associated with suicide attempts in grade 8.
探讨社区暴力暴露与自杀意念及自杀未遂之间的纵向关联，以及抑郁症状和攻击行为是否为该关联中的中介变量。
研究对象为473名城市青少年，主要为非裔美国人，他们在六年级、七年级和八年级时完成了社区暴力暴露、抑郁症状以及自杀意念和自杀未遂的测量；教师报告了这些青少年在六年级、七年级和八年级时的攻击行为。采用路径分析来检验六年级时的社区暴力暴露与八年级时的自杀意念和自杀未遂之间的直接和间接关联。抑郁症状和攻击行为被视为从六年级社区暴力暴露到后期自杀意念和自杀未遂的间接路径的一部分进行检验。
结果显示，社区暴力暴露与后期男性和女性的自杀意念之间存在间接关联；六年级时的社区暴力暴露与七年级时的抑郁症状相关，而七年级时的抑郁症状又与八年级时的自杀意念呈正相关。对于男性而言，六年级时的社区暴力暴露与七年级时攻击行为的增加相关，而七年级时攻击行为的增加又与八年级时的自杀未遂相关。
