童年期人际创伤经历对大学生创伤后心理反应的影响

个体在成长过程中可能会遭受来自家长、教师和同伴的伤害，这些人际创伤经历一方面会增加其大学阶段出现精神障碍的风险，如复杂性创伤后应激障碍（CPTSD），另一方面也可能促进其积极心理改变，实现创伤后成长（PTG）。不过，以往研究大多只考察某一创伤主体或创伤形式产生的消极影响，且一般采用的是变量中心视角。为此，本研究拟从家长、教师和同伴三类主体，身体、情感、关系、性侵害和目睹创伤五种形式，整合童年期人际创伤概念，并开发相应的测评工具。然后，在全国高校选取大学生普通样本和临床样本，运用最新的网络分析方法，从症状网络和维度层面考察不同主体和不同形式的童年期人际创伤与大学生CPTSD六个症状和PTG三个维度的关系，并使用潜剖面分析的方式，从个体中心视角探究不同人际创伤模式对大学生CPTSD各症状和PTG各维度的影响。本项目可为精准识别童年期人际创伤提供支持，为大学生创伤相关心理问题的循证干预提供依据。

Children may expose to interpersonal trauma due to harms from their parents, teachers and peers. The interpersonal trauma could have long-term impact on mental health in their adulthoods. College students are undergoing transition to emerging adulthood and they are susceptible to mental health problems. The interpersonal traumatic experiences in childhood may increase risk for mental disorder in college students and result in complex posttraumatic disorder (CPTSD). They may also experience positive psychological changes, such as posttraumatic growth (PTG). However, most previous studies focused solely on one form of trauma, one type of perpetrator and the negative effects of interpersonal trauma. Moreover, existing literatures were mostly based on latent variable studies, and very few of them adopted person-centered approach in addition to variable-centered approach. In light of this, this study will use a comprehensive concept of childhood interpersonal trauma by integrating three types of interpersonal trauma (i.e. parents, teachers, and peers) and five forms of interpersonal trauma (i.e. physical injury, emotional injury, relationship injury, sexual assault and witnessing trauma), and develop an assessment tool to measure the childhood interpersonal trauma. The study will recruit college students including a general sample and a clinical sample. Network analysis will be conducted to examine the effects of childhood interpersonal trauma on symptom clusters of CPTSD and dimensions of PTG in the two sample groups. Latent profile analysis will be conducted to examine the relationships of different profiles of interpersonal trauma with symptom patterns of CPTSD and dimensions of PTG. This study will provide support to identify the targeted population with childhood interpersonal trauma, and inform critical insights into evidence-based interventions for mental health in young adults with childhood interpersonal trauma.
