Abstract
There is a paucity of indigenous assessment tools to measure severities of romantic jealousy among the Nigerian population despite its high prevalence reported in the literature. The development and validation of a romantic jealousy scale titled Redeemer's University Romantic Jealousy Scale (RUN-RJS) was thus initiated. A principal component analysis extracted 6 components from items whose eigenvalues exceeded 1. Eleven items loaded best in the first component; 9 items loaded in the second component while 12 items loaded in the third component. The scree plot analysis retained three components (romantic jealousy symptoms). The RUN-RJS has a Cronbach's alpha of .89, .89, .86 for the three dimensions of cognitive, emotional and behavioural subscales. Measures of convergent validity and discriminant validity showed that the RUN-RJS is gender-sensitive, has robust psychometric properties and is recommended as a diagnostic tool for romantic jealousy among adults in Nigeria.
