ABSTRACT

Background and Objectives

Locus of control (LOC) is a modifiable mediator of symptoms of posttraumatic stress disorder (PTSD) among traumatized individuals and a potential target of intervention. Compared with studies involving adults, the potential mediation effect of LOC on PTSD symptoms among trauma-exposed children and adolescents is relatively under-explored. This study, therefore, assessed the mediation effects of LOC on the association between lifetime cumulative trauma and PTSD symptoms among a large cohort of adolescents from different cultural background.

Design

Cross-sectional study.

Methods

LOC was determined using the Multi-Dimension Locus of Control Scale; Posttraumatic stress symptoms using the UCLA PTSD Reaction Index; and other significant negative life events using the Life Events Checklist.

Results

Among 3826 adolescents who completed the study, external LOC explained 24% of variance (R² = .24; F_2,3823 = 619.01; p < .01) in PTSD symptoms and had significant indirect effect on the relationship between self-reported cumulative traumatic event exposure and PTSD symptoms (ß = .14; 95% BC CI [.10, .20]). Moderated mediation results showed significant potentiation of the moderation effects among older adolescents; boys; and those from more affluent families.

Conclusions

The study further strengthened the hitherto limited evidence that external LOC partially mediate the relationship between cumulative trauma exposure and PTSD symptoms among adolescents.

外部控制点部分介导了不同背景青少年累积创伤暴露与创伤后应激症状之间的关联

摘要

背景和目标

控制点 (LOC) 是受创伤个体中创伤后应激障碍 (PTSD) 症状的可调节介质，也是干预的潜在目标。与涉及成人的研究相比，LOC 对创伤暴露儿童和青少年 PTSD 症状的潜在中介作用的探索相对不足。因此，本研究评估了 LOC 对来自不同文化背景的大量青少年终生累积创伤与 PTSD 症状之间关联的中介作用。

设计

横断面研究。

方法

LOC 是使用多维轨迹控制量表确定的；使用加州大学洛杉矶分校 PTSD 反应指数的创伤后应激症状；和其他使用生活事件清单的重大负面生活事件。

结果

在完成研究的 3826 名青少年中，外部 LOC 解释了 PTSD 症状中24% 的方差（R ² = .24；F _2,3823 = 619.01；p < .01），并且对自我报告的累积创伤性事件暴露和 PTSD 症状（β = .14；95% BC CI [.10, .20]）。适度的调解结果表明，在年龄较大的青少年中，调解效果显着增强；男孩们; 和那些来自更富裕家庭的人。
