The present study aimed to look at predictors of sexual infidelity online (SIO) and emotional infidelity online (EIO) and also at predictors of jealousy responses towards such behaviours. Gender, narcissism and extraversion were used to do this. A self selecting sample of 173 participants completed questionnaires online about past cheating behaviours, emotional responses to a partner’s infidelity ( modified Buss et al., 1999)), narcissism (NPI-16) and extraversion (subset from Big 5). A between and within participants observational group differences design and a correlation design were used. Gender and extraversion were found to be predictors of SIO whereas narcissism was found to be a predictor of EIO. No significant gender differences (GD) were found in jealousy responses to SIO or EIO. Females were found to be significantly more jealous towards SIO than EIO whereas males did not differ significantly. No significant correlation was found between jealousy and narcissism or jealousy and extraversion.
