Abstract: Work is a double-edged sword. It fosters well-being but it is also linked to stress and burnout. Recognizing that stress is ubiquitous and best understood encompassing both the objective and subjective perspective, this study focuses on evaluating the psychometric properties of the Spanish adaptation of the Perceived Occupational Stress Scale (POSS). In Study 1, we translated and back-translated the POSS and administered it to 675 Spanish individuals. The Spanish POSS showed strong internal reliability (α = 0.903) and a good fit with the proposed factor structure (CFI = 0.946, RMSEA = 0.206, SRMR = 0.031). Study 2 explores the impact of faking on participants' responses using an experimental design. Our findings underscore the significance of work-related factors, such as mistreatment and lack of appreciation, in predicting faking behavior. In Study 3, we delved into the nomological network of the POSS by examining correlations with related psychological variables. Notably, we only found positive correlations between perceived occupational stress and measures of work engagement and psychosocial factors. Overall, the Spanish POSS demonstrates strong validity and reliability, closely mirroring the original scale. As an EU-compliant tool, it effectively assesses perceived occupational stress, enhancing organizational support evaluations and deepening our understanding of occupational well-being.
