Mentalizing Self and Other and Affect Regulation Patterns in Anorexia and Depression

Area of Science:

• Psychiatry
• Clinical Psychology
• Developmental Psychology

Background:

• Mentalizing and affect regulation are crucial for psychological health.
• Deficits in these areas are implicated in various psychiatric disorders, including eating disorders (EDs).
• Understanding these processes in anorexia nervosa (AN) and depression is vital for targeted interventions.

Purpose of the Study:

• To investigate general and affective mentalizing, and affect regulation patterns in female adolescents and young adults with AN and depression compared to controls.
• To examine the predictive and mediating roles of affect regulation and mentalizing variables in eating disorder symptoms.
• To explore the relationship between these constructs and depressive symptomatology.

Main Methods:

• Comparative study involving female inpatients with AN (n=41), depression (n=20), and healthy controls (n=53).
• Assessment tools included measures of reflective functioning (RF), emotion recognition, theory of mind (ToM), alexithymia, affect regulation, depression, and ED symptoms.
• Statistical analyses examined group differences, predictive abilities, and mediation effects.

Main Results:

• Both AN and depression groups showed lower general mentalizing and higher alexithymia, emotional reactivity, and emotional cutoff than controls.
• No significant differences were found between the AN and depression groups on these measures.
• Elevated mentalizing and adequate affect regulation individually predicted lower ED symptom severity, but affect regulation did not add predictive value beyond mentalizing.
• Alexithymia and depressive symptoms were significant predictors of greater ED symptomatology.
• Alexithymia directly and indirectly (via emotional hyperactivation and depression) predicted ED symptoms.

Conclusions:

• Deficiencies in mentalizing and affect regulation are not exclusive to AN but are associated with psychopathology more broadly.
• Alexithymia and depression appear to be key factors contributing to the severity of eating disorder symptoms.
• Affect regulation deficits are primarily linked to depressive symptoms, with emotional hyperactivation indirectly related to AN through depression.
