Resumen: The need for more longitudinal studies (i.e. daily diary and experience sampling studies) focused on counterproductive work behaviours such as bullying requires shorter scales that at the same time do not compromise their content validity. Our main objective is to develop and validate a reduced version of the Workplace Bullying Scale (Escala de Abuso Psicológico Aplicado en el Lugar de Trabajo): the EAPA-T-R. Two studies (Study 1: 1506 and Study 2: 932 employees, respectively) were conducted to evaluate its psychometric properties and to ensure the external validity of the EAPA-T-R. Correlation and regression analyses were performed to reduce the current 12-item scale to a more parsimonious 4-item scale. Moreover, the psychometric properties of potential models were compared. Subsequently, the new scale was assessed using confirmatory factor analysis. Likewise, statistically significant relationships were found between the EAPA-T-R and other dimensions evaluated, such as job characteristics, transformational leadership, engagement, job satisfaction, and subjective performance. Moreover, bullying mediated the relationship between transformational leadership and burnout. To sum up, the EAPA-T-R showed good reliability and validity across studies, supporting its use in future research. The benefits of this short scale for daily diary and experience sampling studies and when using large surveys are discussed.
