This article aims to describe the development of a reduced version of the Romantic Jealousy Scale (RJS), gathering evidence of its psychometric adequacy. Two studies were conducted. Study 1 involved 301 people with a mean age of 29 years (54.2% women), who answered RJS and demographic questions. Results supported the psychometric adequacy of RJS, for which principal component analysis revealed two components (threat andnon-threat), showing Cronbach's alphas greater than 0.70. Furthermore, in Study 2, there were 281 participants with a mean age of 24 years (51.6% women), who answered the same questionnaire as in the previous study. Results of confirmatory factor analysis endorsed the two-factor solution, resulting in a reduced measure with 15 items, whose factors also revealed Cronbach's alphas greater than 0.70. In conclusion, RJS seems to be an instrument revealing an evidence of factorial validity and reliability, thereby being useful in both clinical and research contexts.
