Effects of a Job Demand-Control-Support intervention on managers' depression, anxiety, and stress

This study tested the impact of a job-demand-control-support (JDCS) model intervention on depression, anxiety, and stress (DAS) levels among Brazilian remote managers. The intervention aimed to enhance perceived control and coping strategies, reducing DAS levels. The intervention protocol is presented in detail. A longitudinal field experiment with 122 managers used a mixed-method approach across three stages: pre-intervention, intervention, and follow-up after 3 months. Managers were divided into intervention (n=33) and control (n=34) groups. The Goodness-of-fit indices of Job Demand Control Support and DASS area presented. Results revealed that social support reduced perceived demands in the intervention group, serving as a protective factor within the JDCS model. Additionally, demands acted differently between groups, highlighting a dynamic interaction.

本研究考察了工作需求-控制-支持模型（Job Demand-Control-Support, JDCS）干预对巴西远程管理者抑郁、焦虑与压力（Depression Anxiety Stress, DAS）水平的影响。该干预旨在提升个体的感知控制感与应对策略，进而降低DAS水平，本研究详细呈现了完整的干预方案。
本次研究采用混合研究方法（mixed-method）设计，面向122名管理者开展了三阶段纵向实地实验，涵盖干预前阶段、干预实施阶段与3个月后随访阶段。所有管理者被划分为干预组（n=33）与对照组（n=34）。
本研究同时呈现了工作需求-控制-支持模型与DASS领域的拟合优度指标。结果显示，干预组内的社会支持可降低管理者感知到的工作需求，在JDCS模型中发挥保护因子的作用。此外，两组间的工作需求呈现出差异化的作用模式，凸显出动态交互效应。
