Predicting Academic Achievement Based on Grit as a Personality Trait with Mediating Role of Goal Orientation among MA Students of Shiraz University

The purpose of this study was to predict academic achievement based on Grit as a personality trait، through mediating role of goal orientation. Participants of current study included 356 MA students (177 girls and 179 boys) of University of Shiraz and were chosen by stratified random sampling method. They filled 12-item scale of Grit and 24-item scale of goal orientation (AGQ). Data analysis was done by using Pearson correlation and hierarchical multiple regression based on Baron and Kenny (1986) procedure. To evaluate the fitness of proposed model LISREL -8/80 was utilized. Results indicated a significant positive relationship between Grit with achievement and approach goal orientation (both performance and mastery)، also there was no significant relationship between Grit and avoidance goal orientations (both performance and mastery). Meditative role of the approach goal orientation (both performance and mastery) was confirmed to predict academic achievement.
