Police-initiated post-traumatic stress symptomatology (PI-PTSS) refers to post-traumatic stress symptoms that are rooted in interactions with police officers. Research on PI-PTSS is scarce, though results typically suggest that invasive police behaviors are associated with higher levels of PI-PTSS. However, this research utilizes a general measure of PI-PTSS, failing to account for unique profiles of PI-PTSS that may be present in the data. Further, research has yet to the relationship between PI-PTSS and co-morbidities. The present study utilizes latent class analysis (LCA) to identify profiles of PI-PTSS, tests predictors of latent class membership, and tests latent classes as predictors of depressive symptomatology among a sample of 816 youth in the Fragile Families and Child Wellbeing Study. Findings from identified three profiles of PI-PTSS: low PI-PTSS, avoidance, and high PI-PTSS. The odds of belonging to the high PI-PTSS are greater for youth in low-income households, black youth, and youth who have been stopped by the police multiple times. Membership in the high PI-PTSS class is also associated with higher levels of depressive symptomatology. Our findings highlight the need to develop tactics that minimize the negative impact that police can have when responding to crime, and create mechanisms that increase the effectiveness of police when responding to non-crime situations that require a social service response.

警察发起的创伤后应激症状（PI-PTSS）是指创伤后应激症状，其根源于与警官的互动。对PI-PTSS的研究很少，尽管结果通常表明，侵入性警察行为与更高水平的PI-PTSS相关。但是，这项研究利用了PI-PTSS的一般度量，无法说明可能存在于数据中的PI-PTSS的唯一配置文件。此外，还没有研究PI-PTSS与合并症之间的关系。本研究利用潜在类别分析（LCA）来识别PI-PTSS的概况，测试潜在类别成员的预测因子，并在脆弱家庭和儿童福利研究的816个样本中测试潜在类别作为抑郁症状的预测因子。从确定的PI-PTSS的三个配置文件中得出的结果：PI-PTSS低，避免和PI-PTSS高。低收入家庭中的青年，黑人青年和多次被警察阻止的青年，属于高PI-PTSS的几率更大。高PI-PTSS级别的成员也与抑郁症状的高水平相关。我们的发现强调需要制定策略，以最大程度地减少警察在应对犯罪时可能产生的负面影响，并建立机制来提高警察在应对需要社会服务应对的非犯罪情况时的效力。高PI-PTSS级别的成员也与抑郁症状的高水平相关。我们的发现强调需要制定策略，以最大程度地减少警察在应对犯罪时可能产生的负面影响，并建立机制来提高警察在应对需要社会服务应对的非犯罪情况时的效力。高PI-PTSS级别的成员也与抑郁症状的高水平相关。我们的发现强调需要制定策略，以最大程度地减少警察在应对犯罪时可能产生的负面影响，并建立机制来提高警察在应对需要社会服务应对的非犯罪情况时的效力。
