Abstract.
Exposure to traumatic events is an inherent aspect of first responder work, placing individuals at heightened risk for post-traumatic stress disorder (PTSD) and burnout. This study examined the relationship between PTSD symptoms and two key dimensions of burnout-emotional exhaustion and depersonalization-among South African first responders, with a particular focus on the mediating role of psychological hardiness.
A total of 429 participants (police officers and paramedics) completed the PTSD Checklist for DSM-5 (PCL-5), the Short Hardiness Scale, and the Emotional Exhaustion and Depersonalization subscales of the Maslach Burnout Inventory.
Path analysis revealed that the control and challenge dimensions of hardiness partially mediated the relationship between PTSD and burnout. While higher control was associated with lower burnout, higher challenge was unexpectedly associated with greater burnout. This suggests that different hardiness dimensions play distinct roles in the PTSD-burnout relationship. In contrast, the commitment dimension did not mediate this relationship.
These findings highlight the nuanced and multidimensional role of hardiness in trauma-exposed populations and underscore the importance of resilience-focused interventions that enhance perceived control and constructive engagement with challenge to mitigate burnout in high-risk occupational groups.
摘要。
接触创伤性事件是急救人员工作的一个固有方面,使个体患创伤后应激障碍(PTSD)和职业倦怠的风险增加。本研究考察了南非急救人员中PTSD症状与职业倦怠的两个关键维度——情感耗竭和去人格化之间的关系,特别关注心理韧性的中介作用。
共有429名参与者(警察和护理人员)完成了《精神疾病诊断与统计手册》第5版创伤后应激障碍检查表(PCL - 5)、简短韧性量表以及马氏职业倦怠量表的情感耗竭和去人格化分量表。
路径分析显示,韧性的控制和挑战维度部分中介了PTSD与职业倦怠之间的关系。虽然较高的控制与较低的职业倦怠相关,但较高的挑战却意外地与较高的职业倦怠相关。这表明不同的韧性维度在PTSD - 职业倦怠关系中发挥着不同的作用。相比之下,奉献维度并未中介这种关系。
这些发现凸显了韧性在受创伤人群中所起的细微且多维度的作用,并强调了以恢复力为重点的干预措施的重要性,这些措施可增强感知到的控制感以及对挑战的建设性应对,以减轻高风险职业群体中的职业倦怠。
