Abstract
To determine if locus of control and perceived cohesiveness of a group had singular and joint effects on experienced satisfaction with coworkers 281 scientists and engineers in 15 Research and Development organizations were tested. Main effects and the interaction of the predictors were significant. Persons scoring internally were less satisfied with coworkers than were those who scored externally. Cohesiveness was significantly related to the criterion and subjects designated as externally oriented demonstrated a stronger relationship between perceived cohesiveness and satisfaction with coworkers than their internally oriented counterparts.
