Abstract (530 Views)
Aims: Stress inoculation training, a cognitive-behavioral intervention, has demonstrated efficacy in stress reduction among high-risk professions; however, evidence in Latin America remains limited. This study aimed to evaluate the effectiveness of stress inoculation training in reducing occupational stress, enhancing resilience, and improving job satisfaction and well-being among operational personnel of the Ambato Fire Department in Ecuador.
Materials & Methods: This quasi-experimental pre-post study with a non-equivalent control group was conducted between January and June 2023. Sixty firefighters were recruited and allocated to either the stress inoculation training group (n=30) or the control group (n=30). The stress inoculation training group underwent eight sessions (30 minutes each, twice weekly) that included relaxation training, cognitive restructuring, and coping skills rehearsal. Stress was assessed using the ILO-WHO Work Stress Scale, resilience was measured with the Connor-Davidson Resilience Scale, job satisfaction was evaluated with the Job Satisfaction Survey, and well-being was assessed with the OWQ. Physiological biomarkers (salivary cortisol and resting heart rate) were also measured.
Findings: The stress inoculation training group showed a significant reduction in occupational stress scores (from 109.2±13.5 to 65.7±18.4; p<0.001), accompanied by decreases in salivary cortisol and resting heart rate. Significant improvements were also observed in resilience, job satisfaction, and occupational well-being. The control group exhibited minimal, non-significant changes across all outcomes.
Conclusion: Stress inoculation training is effective in reducing occupational stress and improving resilience, job satisfaction, and overall well-being among firefighters in Ecuador.
