Alexithymia, emotion dysregulation, impulsivity and aggression: A multiple mediation model

Area of Science:

• Psychology
• Psychiatry
• Neuroscience

Background:

• Aggressive behaviors cause significant harm, necessitating research into their underlying mechanisms.
• Poor emotional awareness (alexithymia), emotion dysregulation, and impulsivity are potential contributors to aggression.

Purpose of the Study:

• To investigate the relationships between alexithymia, emotion dysregulation, impulsivity, and aggression.
• To compare these relationships in a clinical psychiatric sample and a general community sample.

Main Methods:

• Cross-sectional study comparing a mixed psychiatric sample (N=257) and a community sample (N=617).
• Statistical analysis to examine mediation and direct effects between the studied constructs.
• Exploration of specific dimensions of emotion dysregulation and impulsivity.

Main Results:

• The clinical sample exhibited higher levels of alexithymia, emotion dysregulation, impulsivity, and aggression compared to the community sample.
• In the community sample, emotion dysregulation and impulsivity mediated the link between alexithymia and aggression.
• In the clinical sample, only emotion dysregulation significantly mediated the alexithymia-aggression relationship, with Negative Urgency being particularly relevant.

Conclusions:

• Alexithymia and emotion dysregulation are crucial factors in understanding aggression.
• Emotion dysregulation and specific impulsivity dimensions are important targets for interventions aimed at reducing aggressive behaviors.
• Findings suggest tailored treatment approaches for aggression, considering emotional processing and regulation deficits.
