Attachment and emotional regulation: examining the role of prefrontal cortex functions, executive functions, and...

Attachment is a prominent area of psychological research, with its relevance linked to executive functions, mindfulness, and emotional regulation. The purpose of this study is to examine this relationship among these aforementioned four constructs and propose a model to be tested in the future. Based on the current trends using the Interpersonal Neurobiology approach, which assumes prefrontal cortex functions to include other socioemotional resources such as empathy, morality, insight, behavior, and body regulation. Our study included prefrontal cortical functions alongside executive functions. The assessment instruments used were Attachment-Based Cognitive Representations Scale, Prefrontal Cortex Functions Scale, Webexec, Five Facet Mindfulness Scale, and Difficulties in Emotion Regulation Scale. We hypothesized that attachment would be the strongest predictor of emotional regulation. The participants in the study were 539 college students (mean = 20.21; sd = 1.57); (68% female and 32%, male). Our a priori research hypothesis was supported, with an additional finding that trait mindfulness was also a significant predictor. The strongest correlations with attachment styles were with trait mindfulness and emotional regulation. We conducted path analyses of two different models for secure and insecure attachment. The path analyses showed that secure attachment scores were negatively related, and insecure attachment scores were positively related to difficulties in emotional regulation scores. Furthermore, trait mindfulness and prefrontal cortex functions also mediated this relationship. However, there was no significant relationship between executive functions and difficulties in emotional regulation scores, even though it was significantly related to attachment. Results and implications are discussed.
