Abstract
Romantic jealousy is a complex emotion activated by a real or perceived threat to the relationship. Romantic jealousy is an important phenomenon in public health, as it brings consequences for the subject, the couple and the rival, even to the point of death. This theory-based study performed a systematic review of the research published in major international databases and platforms, as of December, 2016. The results of 230 studies that met the inclusion criteria were classified in pursuance of the variables associated with jealousy: a) personal variables (differences in sex, sexual orientation, hormones / use of contraceptives, self-esteem, attachment style and use of alcohol); b) interpersonal variables (romantic love, satisfaction and violence); c) sociocultural variables (transcultural comparisons, features of the rival and social networks). Future studies, with sufficient statistical robustness, should achieve a clinical formulation that indicates the relevance and predictive power of each variable.
