Theoretic principles of rational emotive behavior therapy (REBT) and loneliness: a multinational replication of Hyland et al. (2019)

Loneliness has detrimental effects on physical and mental well-being, making relevant any systematic means of inhibiting its impact. Whereas interventions based on cognitive behavior therapies have shown efficacy, interventions based on Ellis's rational emotive behavior therapy (REBT) have not been systematically assessed. In 2019, Hyland et al. demonstrated that the REBT theoretic principles of psychopathology and psychological health significantly predict loneliness scores, providing an empirical justification for later intervention efforts. The Hyland et al. sample was small, with limited demographic and geographic diversity. This paper replicates the Hyland et al. analyses using a larger (<i>N</i> = 3,064) sample drawn from the United States, United Kingdom, Canada, Australia, and South Africa. The present results replicate Hyland et al.'s results for both the psychopathology and psychological health models, with minimal variation in model fit from country to country. Implications for the development of an REBT-based intervention to treat loneliness are discussed.
