Sex differences in jealousy in response to infidelity: Evaluation of demographic moderators in a national random sample

Studies examining sex differences in jealousy have often relied on student samples and were restricted to the evaluation of a selected few moderators. In this study, a nationally representative survey of American households was presented with either an actual or a hypothetical infidelity scenario (which appeared as either a forced choice or as continuous measures). Significant sex differences only emerged for forced choice measures and not for continuous measures. Importantly, this effect appeared most strongly in participants reporting reactions to an actual infidelity. We also explored a number of potential moderators of this effect. These moderators were more influential for the hypothetical than for the actual infidelity scenario. Exploratory analysis of additional demographic variables was conducted.

► Study of sex differences in jealousy with a national random sample.
► Sex differences strongest for forced choice using actual infidelity.
► Moderators identified for forced choice with hypothetical scenario.
► Sex differences did not emerge using continuous measures.
