In this post hoc analysis of mate retention behavior, over 3000 married couples from five cultures completed the Marriage and Relationship Questionnaire (MARQ). The Actor-Partner Interdependence Model (APIM) was used to test relationships for selected variables. For all countries and both sexes, the spouse being attracted to other people was linked to worry about spousal infidelity. For all cases except the Russians, being attracted to one’s spouse was related to less worry by the spouse about infidelity. In all cases, one’s being attractive was associated with spousal feelings of possessiveness. Having a spouse who went out without them was related to infidelity worries for wives in all groups and husbands in three groups. Feelings of possessiveness were related to wanting to touch the spouse in most groups, and husbands reported more such desire in all groups. Husbands who sought sex outside of marriage worried about reciprocal spousal infidelity in all cultures, as did wives in most cultures. Overall, the data suggest that attractiveness and attraction shape mate retention emotions and behavior in similar ways across cultures.
