Background: Prior research indicates that deficits in emotional abilities are key predictors of the onset and maintenance of eating disorders (ED). As a relatively new emotion-related construct, emotional intelligence (EI) comprises a set of basic emotional abilities. Preliminary research suggests that deficits in EI are linked with disordered eating and other impulsive behaviours. Also, previous research reveals that emotional and socio-cognitive abilities, as well as ED symptomatology, varies across lifespan development. However, while the findings suggest promising results for the development of potential effective treatments for emotional deficits and disordered eating, it is difficult to summarise the relationship between EI and ED due to the diversity of theoretical approaches and variety of EI and ED measures.
Objective: Our study, therefore, aimed to systematically review the current evidence on EI and ED in both the general and clinical populations and across different developmental stages.
Methods: The databases examined were Medline, PsycInfo and Scopus, and 15 eligible articles were identified. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were used.
Results: All the studies reviewed indicated negative associations between EI and the dimensions of ED. Additionally, several mechanisms involved, namely adaptability, stress tolerance and emotional regulation were highlighted.
Conclusion: The systematic review suggests promising but challenging preliminary evidence of the associations between EI and the dimensions of ED across diverse stages of development. In addition, future research, practical implications and limitations are discussed.
