Development and validation of the Work Envy Appraisal Scale (WEAS) for Spanish workers.

Envy is an important emotion that affects workers' behavior and performance. Instruments to measure envy are available, but new scales are needed for the analysis of work envy that include appraisals of challenge (benign envy) and threat (malicious envy). Based on Lazarus and Folkman's theory, the objective of this study is to develop and validate the Work Envy Appraisal Scale (WEAS) for Spanish workers. It had been carried out in two studies; in the first study, the scale was constructed and its dimensions were analyzed with a sample of 100 Spanish workers (sample 1). In the second study, the scale was validated and its psychometric properties were analyzed (sample 2, N = 219; sample 3, N = 532). The results of exploratory, confirmatory, and multigroup factor analysis showed good indices of fit for the two-factor structure. Moreover, the results showed adequate convergent and discriminant validity. Furthermore, our findings indicated that the scale is a reliable and valid instrument for measuring envy at work. This way of measuring envy at work (discerning its challenge and threat appraisal) makes it possible to find answers to some recurrent research questions (e.g. social desirability issues, the confusion of envy with other topics, etc.) and can facilitate reliable research on envy at work.
