Ethnic identity and collective self-esteem mediate the effect of anxiety and depression on quality of life in a migrant population

Migration processes can often trigger negative interactions with the context, generating problems in both the physical and mental health of migrants, which have an impact on both their well-being and their quality of life. In this framework, the research aimed to assess the mediating effect of ethnic identity and collective self-esteem on the inverse relationship between mental health problems and quality of life. Data were collected from 908 first-generation Colombian migrants living in Chile, of whom 50.2% were women and with an average age of 35 years. They were assessed with The World Health Organization Quality of Life (WHOQoL)-Bref, Smith’s ethnic identity questionnaire, Basabe’s collective self-esteem, and Beck’s Anxiety and Depression questionnaires. The results provide evidence that both collective self-esteem and ethnic identity exert a partial mediation effect on the relationship between anxiety and depression on quality of life. The study provides evidence of the protective role that the maintenance and reinforcement of ethnic identity and collective self-esteem can have, with a view to strengthening the planning of interventions both in the field of prevention of mental health problems and in the improvement of quality of life based on evidence.
