Conduct problem is an ongoing concern among youth placed in group homes. The concern could sometimes become more challenging due to negative peer influences. The risks associated with negatively influential peers are well-known across diverse residential treatment contexts in the USA, but not in Canada. This 3-year retrospective cohort study observed the influence of positive and negative peers on conduct problems among 173 youths in Ontario group home care between 2012 and 2016 (initial participation rate = 90.0% and follow-up rate = 95.1%). Having previously observed that group home resources matter (Osei in Peer influences on antisocial and prosocial behaviors in group home foster care: Evidence of greater protections in better resourced homes and higher income neighborhoods, Doctoral thesis, University of Windsor, Windsor, Ontario, Canada, 2019, https://scholar.uwindsor.ca/etd/7727/), here it was hypothesized that neighborhood income also matters. Specifically, that neighborhood income would moderate peer influences such that low-income neighborhoods would be relatively risky places, while higher-income neighborhoods would be relatively protective places. Positive and negative peer influences were, respectively, protective and risky, but the main effect of neighborhood income was null. As hypothesized, a significant negative peer influence by neighborhood income interaction was also observed. Higher income neighborhoods attenuated the negative peer influence-youth conduct problem association. Negative peers were less risky in higher income neighborhoods. The main protective influence of positive peers was robust across socioeconomically diverse neighborhoods. Clinical, policy and future research implications are discussed.

行为问题是被安置在集体之家的青少年持续关注的问题。由于同伴的负面影响，这种担忧有时会变得更具挑战性。与具有负面影响的同龄人相关的风险在美国的各种住院治疗环境中众所周知，但在加拿大则不然。这项为期 3 年的回顾性队列研究观察了 2012 年至 2016 年安大略省集体家庭护理的 173 名青少年（初始参与率 = 90.0% 和后续率 = 95.1%）的积极和消极同伴对行为问题的影响。之前已经观察到群体家庭资源很重要（Osei 在 Peer 中对群体家庭寄养中的反社会和亲社会行为的影响：在资源更好的家庭和更高收入社区提供更大保护的证据，博士论文，温莎大学，温莎，安大略，加拿大，2019，https://scholar.uwindsor.ca/etd/7727/)，这里假设社区收入也很重要。具体来说，邻里收入会缓和同龄人的影响，使低收入社区成为相对危险的地方，而高收入社区则是相对保护的地方。积极和消极的同伴影响分别具有保护性和风险性，但邻里收入的主要影响为零。正如假设的那样，还观察到邻里收入互动对同伴的显着负面影响。高收入社区减弱了负面的同伴影响-青年行为问题关联。在高收入社区，消极同龄人的风险较小。在社会经济多样化的社区中，积极同伴的主要保护影响是强大的。临床，
