Abstract. There is a vast literature on the effect of inequality on trust, establishing that equality must be a pre-condition for the emergence of trust. However, most empirical research either focuses on case studies or uses measures of income inequality, such as the Gini index. In this article, we argue that a measure of inequality of opportunities is preferable to focusing on inequality of outcomes, as it taps into the psychological foundations of trust.

Abstract. To analyze the prevalence of burnout syndrome in primary care professionals working in the National Health System. We searched PubMed/MEDLINE, EMBASE, and PsycINFO (up to May 2025).

From each study, methodological characteristics and results were extracted and their quality was evaluated.
