(2023). Effects of three personal resources interventions on employees’ burnout. Scientific Reports, 13. https://doi.org/10.1038/S41598-023-49000-92045-232210.1038/S41598-023-49000-9http://hdl.handle.net/20.500.14454/1967Personal resources are related to positive psychological states that can translate into lower burnout among employees. However, although these personal resources can be promoted through ad hoc interventions, there are few studies that analyze this type of interventions in workers. The aim of this study was to assess the effectiveness of three interventions on personal resources on reducing employees' burnout. To this end, it was hypothesized that a positive psychological capital intervention (PsyCap), a job crafting intervention and a combined intervention would have a positive impact on burnout levels. This research used a quasi-experimental, longitudinal, pretest–posttest design, with repeated measures and a waiting list control group. Study participants (N = 144) were all workers divided into three interventions and a control group. A noteworthy aspect of the study design is that the intervention was implemented as a voluntary online training activity. This study showed that personal resources interventions were effective in reducing burnout among employees. The PsyCap intervention and the combined intervention showed the greatest efficacy. Contrary to expectations, the combined intervention did not show significantly greater efficacy than the other two experimental groups. The study concludes with a discussion of its limitations and practical implications for future personal resources intervention studies.eng© The Author(s) 2023journal article2024-11-19
