The tools administered were Sternberg- Wagner Thinking Styles Inventory and Spielberger’s State-Trait Anger Expression Inventory.Results: Results obtained from this research revealed that there was a statistically significant difference between male and female in liberal and external thinking styles scores, but the study did not show any statistically significant difference between gender and anger management scores. Multiple regression analysis indicated that monarchic, hierarchic, and judicial thinking styles predicted Anger Control-Out, while anarchic and hierarchic thinking styles predicted Anger Expression-Out. Also, hierarchic and global thinking styles predicted Anger Control-In.Conclusion: The present study revealed the role of thinking styles on patterns of expressing and controlling anger. Therefore, its results can be used by university counselors who understand thinking styles to have more efficient behavioral interventions.
