Undersøgelsen med 107 gifte par (17-41 år) fandt, at personlighedstræk som lav samvittighedsfuldhed, høj narcissisme og høj psykotisme var forbundet med utroskab. Desuden var seksuel utilfredshed og konflikter, som jalousi, relateret til utroskab. Kvinder gift med mænd med højere værdi vurderede, at deres mænd var mere tilbøjelige til at være utro.

Hele abstrakt på originalsprog:
Examined 3 sets of possible predictors of infidelity in 107 married couples (aged 17–41 yrs): personality factors; relationship contexts, including recurrent sources of conflict and sexual satisfaction; and the relative “mate value” of the individuals composing a couple. Self-report and spouse-report data on susceptibility to infidelity and self-report, spouse-report, and interviewer-report data on personality, relationship context, and relative mate value were obtained. Results show that personality factors most strongly linked to susceptibility to infidelity were low conscientiousness, high narcissism, and high psychoticism. Relationship contexts linked to susceptibility to infidelity included sexual dissatisfaction and specific sources of conflict, such as partner complaints about jealousy. Women married to men of higher relative mate value provided higher estimates of the likelihood that their husbands will have affairs in the next year.
