Clarifying Anticipated Feelings of Jealousy: Development and Validation of the Anticipated Jealousy Scale.

Abstract

This study examined the construct of anticipated jealousy, conceptually clarifying the components of this construct and creating an optimized scale. Total of 18 items from three widely used self-report measures of jealousy (Multidimensional Jealousy Scale-Emotional Subscale, Anticipated Sexual Jealousy Scale, and Chronic Jealousy Scale) and additional 11 potential anticipated jealousy items were given to 1852 individuals in relationships. Exploratory and confirmatory factor analyses and item response theory (IRT) analyses were used to develop and evaluate the Anticipated Jealousy Scale (AJS). By augmenting the item pool, the results highlighted that anticipated jealousy could take two distinct forms: (1) sexual-getting upset over thoughts of a partner engaging in sexual activity with someone else and (2) possessive-getting upset over a partner forming friendships and emotional bonds with others. IRT analyses helped identify the five most effective items for assessing each of those domains to create the AJS. Results suggested that the subscales of the AJS offered greater precision and power in detecting meaningful differences among respondents than the existing measures, representing short yet psychometrically optimized scales. The AJS subscales demonstrated strong convergent validity with other measures of anticipated sexual and possessive jealousy, and excellent construct and discriminant validity with anchor scales from the nomological net surrounding the construct. Finally, regression analyses demonstrated distinct predictors and correlates for anticipated sexual jealousy, anticipated possessive jealousy, and chronic jealousy. Given the potential utility in distinguishing between the many forms of jealousy, AJS offers an optimized scale measuring anticipated sexual and possessive jealousy.
