Drawing upon previous theorizing and empirical research efforts supporting the importance of role breadth self-efficacy (RBSE) as a key motivational antecedent of proactive forms of behaviour at work, including individual innovation, this paper reports the process of building and validating a Portuguese version of Parker's RBSE scale. Data from two studies with independent samples of employees (N = 103, N = 148) pertaining to an information technology company, showed that this version (RBSE-P) has, as expected, a unidimensional structure with a high level of factor structure similarity in both samples, as well as appropriate levels of internal consistency. Furthermore, evidence from the second sample (N = 148) revealed that, in line with preliminary research, this construct shows validity to predict the distinctive proactive behaviour of individual innovation, evaluated by the employee's corresponding direct supervisors. These results support the use of this scale for assessing RBSE in Portuguese-speaking work settings and the meaningful role of this construct for predicting this criterion, which is acknowledged as an important driver of organizational success and competitiveness.
