The purpose of this study was to examine the mediating effects of achievement goals (performance approach goal, mastery approach goal, performance avoidance goal) on the link between role stress and burnout and engagement.

A total 224 non-commissioned officers agreed to the purpose of this study were participated. A correlation analysis was performed by using SPSS 21.0, and Structural Equation Modeling (SEM) was performed by using AMOS 20.0.

This study were as follows. As a result of comparing the research model including the performance approach goal and the competition model except the performance approach goal, the competition model was excellent. In addition, performance avoidance goal was partially mediated in the relationship between role stress and burnout. In addition, the mastery approach goal was partially in the relationship between role stress and engagement.

The results imply that improving mastery approach goal and decreasing performance avoidance goal is very important for non-commissioned officers. Therefore, the military authorities should develop various strategies to decrease performance avoidance goal and improve the mastery approach goal.

The purpose of this study was to examine the effects of monetary motivation on the relationship between pain-related fear and avoidance behavior.

Eighty healthy volunteers were randomly assigned to one of four groups in accordance with task conditions of pain-related fear (high or low) and monetary motivation (high or low).

The autonomic nervous system was more active in the high pain-related fear group than in the low pain-related fear group as the participants watched a video and performed a task. Also, pain-related fear and monetary motivation had a significant interaction effect on avoidance behavior. High monetary motivation was associated with a shorter delay time during task performance in the high pain-related fear group. No significant difference was observed in the delay time in the low pain-related fear group.

This study provides empirical evidence supporting the modified fear-avoidance model and experimentally proves the activation of the goal shielding mechanism.
