The role of emotional intelligence on the experience of behavioural addictions is a growing area of research interest. However, there are operationalisation issues in studying both emotional intelligence and behavioural addictions separately. This review aims to report on the existing literature of studies exploring the relationship between these two concepts, and to identify gaps in research practice in order to inform future studies. A search, covering the date range of 2013-2024, conducted in five databases in August 2024 identified 43 articles, reported according to PRISMA 2020 guidelines. The findings are discussed under four subheadings: technology-related behavioural addiction, internet gaming disorder, eating disorders, and consumer behaviour and compulsive buying. Overall, the results show that emotional intelligence is negatively correlated with behavioural addictions and plays both a moderating and mediating role in the associations between behavioural addictions and other negative outcomes such as suicidal ideation, rumination, fear of missing out, and depression. In addition to summarising studies and controversial discussions on emotional intelligence and behavioural addictions, this review suggests possible roadmaps to ensure more accurate research outcomes by highlighting the importance of theoretical and methodological distinctions between trait and ability models of emotional intelligence.
