Résumé : Alexithymia has been frequently studied in the context of negative affect frequency but rarely in the context of positive affect frequency or in the context of affect intensity. However, affect intensity and frequency, even if they are independent, are generally confounded due to an overlap in items wording (tapping both dimensions). The aim of the study was to examine the incremental validity of alexithymia for predicting both affect intensity and frequency, regarding positive and negative valence. Two hundred and fifty five students fulfilled measurements for alexithymia, affect intensity and affect frequency. Results showed that the factor "Difficulty identifying feelings" is related to higher positive and negative affect intensity, as well as to negative affect frequency. Men were also more sensitive to positive affect intensity and frequency if they scored higher on alexithymia. They experienced less often positive affect, but the intensity of their affect was more intense. Conversely, alexithymia did not influence women's affect intensity or affect frequency. Thus, alexithymia factors are associated with specific patterns of affect intensity and frequency, highlighting an overall deficit in the processing of emotions with contrasting patterns regarding gender.
