Primary use / Purpose: 

Measures individual’s susceptibility to infidelity, and their perception of the likelihood of their partner’s susceptibilty to infidelity.

Background: 

Infidelity is a major cause of divorce and spousal battering. Little is known, however, about which individuals are susceptible to infidelity, or about the relationship contexts that promote infidelity. Personality factors most strongly linked to susceptibility to infidelity according to the study from which this instrument was created, were low Conscientiousness, high Narcissism, and high Psychoticism. Relationship contexts most strongly linked to susceptibility to infidelity include sexual dissatisfaction, and specific sources of conflict such as partner complaints about jealousy. For the Susceptibility to Infidelity Instrument, participants must estimated the likelihood of their spouses committing each of six types of infidelity with a member of the opposite sex in the next year: flirting, passionately kissing, going on a romantic date, having a one night stand, having a brief affair, and having a serious affair. Participants then provided parallel estimates for their own likelihood of committing the six types of infidelity. Participants provided estimates on separate 11-point scales for each type of infidelity. The low end of the scale indicated 0%, the high end indicated 100%, with the scale marked off in 10% increments.
