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.
