The Relationship between Brain/Behavioral Systems and Alexitimiya by the Mediating Positive and Negative Affect

The aim of present study investigated the mediating role of positive and negative affect in the relationship between systems of brain/behavioral and alexitimiya. 277 students (121 males and 156 females) was selected from Kharazmi University through multistage cluster sampling and completed Jackson,s five factor, Positive and Negative Affect (PANAS), Alexithimiya questionnaires. Data were analyzed using multiple regression. The results showed the behavioral activation/inhibition system positively can predict Alexithymia. Also the positive and negative affect play a mediating role in the relationship between systems and alexithymia. The model obtained is appropriate for explaining alexithymia.
