Self-Schemas

Self-Schemas

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932).

Background:

Loneliness is increasingly recognized as a significant psychosocial factor.
Its specific role in eating disorders (ED) requires systematic investigation.

Purpose of the Study:

To systematically review the literature on loneliness in clinical and subclinical eating disorders.
To assess the impact of loneliness on ED symptom severity and explore underlying mechanisms.

Main Methods:

A comprehensive literature search was conducted following PRISMA guidelines.
Included studies quantitatively measured loneliness and ED symptoms in diagnosed or subclinical populations.
Bias was assessed using the Downs and Black checklist.

Main Results:

Loneliness is a transdiagnostic factor in ED, associated with increased symptom severity.
In Bulimia Nervosa and Binge Eating Disorder, loneliness mediated emotional dysregulation.
In subclinical samples, loneliness may be an early correlate of ED symptoms, especially in young adults.

Conclusions:

Loneliness significantly impacts ED development and persistence.
Interventions focusing on social support and emotional regulation may benefit ED treatment.
Further research is needed on gender and population diversity.
