The purpose of the present research was to investigate the structural relationships of role differentiation, cohesion, team member satisfaction, and perceived group performance and to examine the moderating effects of barrack’s structure and squad leader’s initiating structure in these relationships. A total of 924 ROK Army soldiers participated in this research and data were collected through survey. Results of the structural equation modeling analysis showed that role differentiation was positively related to cohesion, team member satisfaction, and perceived group performance, respectively. Also, cohesion mediated the relationships between role differentiation and team member satisfaction as well as between role differentiation and perceived group performance. The moderating effect of barrack’s structure in the relationship between role differentiation and team member satisfaction was significant, suggesting that team member satisfaction was higher in the hierarchical barrack than in the horizontal barrack when soldiers perceived that the role differentiation was high. The moderating effect of squad leader’s initiating structure in the relationship between role differentiation and perceived group performance was also significant, suggesting that the relationship between role differentiation and perceived group performance was stronger when squad leader’s initiating structure was high than low. Lastly, the results, implications, and limitations of this research were discussed.
The Self-determination theory (SDT) posits the existence of distinct taxonomy of motivation (i.e., amotivation, external, introjected, identified, integrated, and intrinsic motivation). The purpose of this study was to explore whether SDT’s work motivation structure can be applied to the understanding that of Korean employees, and to identify the motivational profiles for Korean employees together with their relationships with a variety of organizational outcomes. Data was collected from two separate samples of Korean employees(Study 1: 509 employees; Study 2: 153 employees). The results showed that unlike SDT taxonomy, autonomous motivations were not classified into three distinctive categories(identified, integrated, and intrinsic motivation). The results also revealed that there were three distinct motivational profiles(i.e., autonomous motivated, controlled motivated, and amotivated), and the largest proportion of Korean employees was covered by controlled motivated cluster. The autonomous motivated cluster had the most favorable levels of adaptive organizational outcomes(i.e., organizational commitment, job satisfaction), whereas the amotivated cluster was strongly related to non-adoptive organizational outcomes(i.e., turnover, emotional exhaustion). Based on these results, discussion was made regarding the distinct features of work motivation structure and motivational profiles in Korean work setting, and also future research directions were suggested.
