Research suggests that neighborhood risks are associated with internalizing symptoms for adolescents high on temperament characteristics related to the behavioral inhibition system (BIS). However, it is unclear whether newer conceptualizations of the BIS distinguishing fear from anxiety operate similarly. Furthermore, it is unclear whether the BIS attenuates community violence exposure effects on externalizing problems. The current study examined whether the BIS or the fight-flight-freeze system (FFFS) moderated associations between community violence exposure and internalizing and externalizing problems. Participants were 367 urban African American adolescents who reported on temperament characteristics in grade 9, and community violence exposure and adjustment problems in grades 9 and 10. Hierarchical linear regression analyses indicated that the FFFS, but not the BIS, moderated the association between community violence exposure and aggressive behavior. Grade 9 community violence exposure was positively associated with grade 10 aggression for adolescents low on FFFS, suggesting that the FFFS may partly differentiate community violence-exposed adolescents' aggressive behavior.
研究表明，邻里风险与行为抑制系统（BIS）相关气质特征较高的青少年的内化症状有关。然而，尚不清楚将恐惧与焦虑区分开来的BIS的新概念是否具有类似作用。此外，尚不清楚BIS是否会减弱社区暴力暴露对外化问题的影响。本研究考察了BIS或战斗-逃跑-冻结系统（FFFS）是否调节了社区暴力暴露与内化和外化问题之间的关联。研究参与者为367名城市非裔美国青少年，他们报告了九年级时的气质特征，以及九年级和十年级时的社区暴力暴露情况和适应问题。分层线性回归分析表明，FFFS而非BIS调节了社区暴力暴露与攻击行为之间的关联。对于FFFS水平较低的青少年来说，九年级时的社区暴力暴露与十年级时的攻击行为呈正相关，这表明FFFS可能在一定程度上区分了遭受社区暴力的青少年的攻击行为。
