Emotional Dispositions and Substance Use: Mediating Effect of Alexithymia

Abstract : Substance consumption behaviors can range from use to abuse, the latter including addictive behaviors. Relationships between emotionality, alexi-thymia and substance-consumption behaviors among young adults were investigated through an explanatory model wherein alexithymia fulfills a mediating function by acting as an emotion-adjustment process. 256 students (62.1% women) with a mean age of 20.7 yr. (SD = 1.6), enrolled at two universities in southern france took part in the study. They filled out a substance-use questionnaire, the Émotion-nalité positive et négative à 31 (EPn-31) emotionality scale, and the 20-item toronto alexithymia scale (tas-20). mediation analyses validated the hypothesis that emotional dimensions of alexithymia act as mediators between emotionality (nega-tive emotionality and emotional arousal) and substance use. as a mediating factor, alexithymia may be regarded as a type of operational process that regulates emotions. these results could have important implications for clinical and therapeutic applications focusing on emotion-regulation strategies and substance use.
