Abstract: Abstract Monitoring precarious employment (PE) is crucial to design and evaluate policies tailored to enhance the quality of employment and to achieve more decent and sustainable labour markets. In that regard, the construction of theory-based multidimensional measurement instruments with data derived from well-established and periodically-conducted surveys stands out as an insightful opportunity to acquire so. Accordingly, this study aims to adapt the Employment Precariousness Scale (EPRES) to the available information in the European Working Conditions Survey VI (EWCS-2015), and to explore the psychometric properties and construct validity of the ensuing instrument, namely EPRES-E, in Spain. 13 items sorted in six dimensions (temporariness, disempowerment, vulnerability, exercise of rights, uncertain working times and wages) shaped the EPRES-E. In a sample of 2442 formal employees residing in Spain, item- and scale-level analyses were performed alongside omega reliability coefficients and confirmatory factor analyses (CFA). The scale exhibited good psychometric properties and reliability (ω = 0.80 for the EPRES-E score and near or above 0.70 for all subscales excepting “exercise of rights”). The factor structure was confirmed by CFA [χ2 (df) = 530.432 (58), p
