Consistent with other jealousy measures, evidence of three factors emerged: emotional, cognitive, and behavioral jealousy.DiscussionThese studies indicate that the OJS is a reliable and valid instrument.ImplicationsThis measure fills the need for a valid, reliable assessment of online jealousy and can be used in research about online jealousy across age and relationship type. It may also be useful for individual or couple therapy.
