According to the Dimensional Model of Adversity and Psychopathology (DMAP), childhood trauma (CT) can be categorised into two dimensions: abuse and neglect. While CT is widely recognized as a risk factor for obsessive-compulsive symptoms (OCS), the specific dimension that primarily contributes to this risk remains unclear. This study sought to distinguish the effects of different CT dimensions on the developmental trajectory of OCS. A total of 3535 Chinese college freshmen (Age = 18.01, Age = 0.77; 65.60% female) participated in a 3-year, 5-waves longitudinal tracking study. A latent growth curve model (LGCM) was constructed to examine the effects of two CT dimensions (abuse and neglect) on the developmental trajectory of OCS. Sex and recent perceived stress were also added to the conditional LGCM. Results showed that the rates of 'moderate to severe' emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect were 3.68%, 3.62%, 5.57%, 10.46%, and 19.54%, respectively. The unconditional LGCM revealed a U-shaped developmental trajectory of OCS. The conditional LGCM revealed that childhood experiences of abuse, rather than neglect, significantly predicted the intercept (β = 0.159, p < 0.001), the linear slope (β = -0.222, p < 0.01), and the quadratic slope (β = 0.195, p < 0.05) of the trajectory of OCS. Specifically, higher abuse levels were associated with higher initial OCS levels and a slower rate in linear downtrend of OCS over time, resulting in a U-shaped trend. Besides, sex did not predict the developmental trajectory of OCS. These findings highlight the association between childhood experiences of abuse, rather than neglect, with the development of OCS and may provide targeted direction and guidance for preventing OCS among Chinese college students.
根据逆境与精神病理学维度模型（DMAP），童年创伤（CT）可分为两个维度：虐待和忽视。虽然童年创伤被广泛认为是强迫症状（OCS）的一个风险因素，但主要导致这种风险的具体维度仍不清楚。本研究旨在区分不同童年创伤维度对强迫症状发展轨迹的影响。共有3535名中国大学新生（年龄=18.01，年龄标准差=0.77；65.60%为女性）参与了一项为期3年、共5波的纵向跟踪研究。构建了一个潜在增长曲线模型（LGCM），以检验两个童年创伤维度（虐待和忽视）对强迫症状发展轨迹的影响。性别和近期感知到的压力也被纳入到条件LGCM中。结果显示，“中度至重度”情感虐待、身体虐待、性虐待、情感忽视和身体忽视的发生率分别为3.68%、3.62%、5.57%、10.46%和19.54%。无条件LGCM显示强迫症状呈U形发展轨迹。条件LGCM显示，童年期的虐待经历而非忽视经历，能显著预测强迫症状轨迹的截距（β=0.159，p<0.001）、线性斜率（β=-0.222，p<0.01）和二次斜率（β=0.195，p<0.05）。具体而言，更高的虐待水平与更高的强迫症状初始水平相关，且随着时间推移强迫症状线性下降趋势更慢，从而导致U形趋势。此外，性别并不能预测强迫症状的发展轨迹。这些发现凸显了童年期虐待经历而非忽视经历与强迫症状发展之间的关联，并可能为预防中国大学生的强迫症状提供有针对性的方向和指导。
