A relação entre estresse e qualidade de vida no trabalho : evidências quantitativas em um Instituto Federal de Educação

Abstract

This study aimed to analyze the relationship between perceived stress and Quality of Work Life (QWL) among employees of a Federal Institute of Education (IF), considering length of service as a moderating variable. The research adopted a quantitative, descriptive-explanatory design, applying a structured survey to administrative staff and faculty members. The variables were measured using validated instruments - the Perceived Stress Scale (PSS) and the Quality of Work Life Questionnaire (QWLQ) - ensuring the consistency of the results. Data analysis employed comprehensive statistical procedures, including descriptive statistics, group difference tests (means and ANOVA), Structural Equation Modeling (SEM), and Multigroup Analysis to examine the moderating role of length of service, thus ensuring high methodological rigor. The findings demonstrated that stress negatively affects QWL, compromising occupational well-being. Furthermore, length of service was shown to play a moderating role, as more experienced employees displayed greater ability to cope with workplace pressures, thereby attenuating the adverse effects of stress. Relevant differences were also identified between professional categories, organizational units, and gender, highlighting important specificities of the institutional context under study. It is concluded that stress is a key determinant of QWL, although accumulated professional experience can partially mitigate its impacts. These results underscore the importance of institutional policies aimed at preventing stress and fostering healthier and more sustainable work environments. In addition to providing practical insights for public sector people management, the study contributes directly to the institution by offering evidence to guide psychological support programs, stress management training, and professional development initiatives, thus promoting employees well-being and improving organizational climate. Academically, the research advances knowledge by highlighting the moderating role of length of service in the relationship between stress and QWL, thereby strengthening the debate on quality of life and occupational health among public servants in Brazil.
