While jealousy has a negative link to individual and conjugal well-being, few valid French-language instruments are available. This article presents a translation of the Multidimensional Jealousy Scale (Pfeiffer & Wrong, 1989) and the validation of its French version, Échelle multidimensionnelle de jalousie, a 24-item questionnaire evaluating the cognitive, affective and behavioural dimensions of jealousy. Psychometric qualities of the questionnaire are evaluated through two independent samples. In Study 1 (N = 300), exploratory factorial analysis suggests a three-dimensional structure of an abridged questionnaire of 15 items. Criterion related validity and fidelity (internal consistency) are also examined. In Study 2 (N = 381), confirmatory factorial analyses support the three-dimensional structure of the 15-item version. These results support the use of a 15-item multidimensional jealousy scale. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
