InvestAigation into the Relationship between Sensory processing sensitivity and Alexitimiya by the Mediating Role of the Positive and Negative Affect

Present research aims to show the mediating role of Positive and Negative Affect in the relationship between Sensory processing sensitivity and Alexitimiya. A sample comprising of 277 students (121 males and 156 famales) was selected from amongKharazmi University studentsthrough multistage cluster sampling method. The statistical instrumentsSensory processing sensitivity(Aron & Aron)questionnaire, Positive and Negative Affect (PANAS) Inventory, Alexithimiya Inventory. Data were analyzed using multiple regression by stepwise method Pearson correlation coenfficient tests with Spss18 software were used.
