Analysis of the mediating effect of mentalization on the relationship between attachment styles and emotion dysregulation.

The current study aims to explore the relationship between attachment styles, mentalization and emotion dysregulation. Moreover, the mediation effect of mentalization in the relationship between attachment and emotion dysregulation is analyzed. A sample composed of 607 participants taken from the Spanish general population completed the measures in a cross-sectional designed study. The results show that secure attachment is negatively related to emotion dysregulation dimensions, whereas insecure attachment styles show a positive correlation. Furthermore, the mentalization variables are in general significantly related to emotion dysregulation. The mediation model shows a large mediational effect size (f  = 2.64). The results suggest that mentalization significantly mediates the relationship between emotion dysregulation and preoccupation, self-sufficiency, and childhood trauma. These results have important implications, as they indicate that clinical interventions on mentalization should reduce emotion dysregulation even in those people with a predominant insecure attachment style.
