The gaslighting relationship exposure inventory: Reliability and validity in two cultures

Gaslighting, a form of psychological abuse, has received increasing attention in recent years. The current research provides reliability and validity evidence for a new 11-item measure of exposure to gaslighting by a romantic partner: The Gaslighting Relationship Exposure Inventory (GREI). Two studies were conducted with Israeli (N = 509) and American (N = 395) community samples. Participants were involved in a romantic relationship and completed an online questionnaire that included measures of intimate partner violence (IPV) victimization, depression, and relationship satisfaction. In both studies, the GREI items loaded onto a single factor of relationship gaslighting exposure. The scale demonstrated metric gender invariance and was reliable in both men and women. Relationship gaslighting exposure was strongly linked with psychological abuse victimization and weakly linked with other forms of IPV victimization, thus showing strong convergent and discriminant validity. Moreover, relationship gaslighting exposure was associated with greater depression and lower relationship quality, above and beyond other forms of IPV victimization. The results support the reliability and validity of the GREI in both men and women, as well as its utility for the study of gaslighting exposure within relationships. The current research highlights that gaslighting is a distinct form of psychological abuse with unique implications for personal and relational well-being.
