Review of psychological literature shows a progressive shift of perspective on occupational safetyaway from an individualistic conception, for which the injury causality resides in the individual (Greenwood & Woods, 1919; Tiffin & McCormick, 1980; Wallace & Vodanovich, 2003), to a psycho social perspective, which integrates individual characteristics with influences associated with an employee’s membership in one or more groups (A. Ho & Leung, 1998; Roethlisberger & Dickson, 1939; Watson, Scott, Bishop, & Turnbeaugh, 2005; Zohar, 2000).
