The current study introduces an ultra-short, 3-item version of the Utrecht Work Engagement Scale. Using five national samples from Finland (N = 22,117), Japan (N = 1,968), the Netherlands (N = 38,278), Belgium/Flanders (N = 5,062), and Spain (N = 10,040) its internal consistency and factorial validity vis-à-vis validated measures of burnout, workaholism, and job boredom are demonstrated. Moreover, the UWES-3 shares 86-92% of its variance with the longer nine-item version and the pattern of correlations of both versions with 9 indicators of well-being, 8 job demands, 10 job resources, and 6 outcomes is highly similar with an average, absolute difference between correlations of only .02. Hence, it is concluded that the UWES-3 is a reliable and valid indicator of work engagement that can be used as an alternative to the longer version, for instance in national and international epidemiological surveys on employee's working conditions.
