Hello, I am a doctoral student. I'm about to collect data on the Organizational Citizenship Behavior scale. The scale was from the following paper:
Williams, L.J. & Anderson, S.E. (1991). Job satisfaction and organizational commitment as predictors of organizational citizenship and in-role behaviors. Journal of Management, 17, 601-617.
But how can I get the questionnaire? Do I need a license or permission to use this scale?
