Positive illusions about a partner's physical attractiveness and relationship quality

The present research examined the existence of positive illusions about a partner's physical attractiveness and its relations to relationship quality. Positive illusions were assumed to exist when individuals rated their partner as more attractive than their partner rated him or herself. In two Dutch community samples of 117 and 203 married or cohabiting heterosexual couples, both partners rated their own and their partner's facial and bodily attractiveness. In Study 2, both partners completed three measures of relationship quality. Both studies found evidence for the existence of positive illusions about a partner's physical attractiveness. Moreover, Study 2 found clear positive illusion actor effects for relationship quality. This association differed by age of couples.     

Women's well-being: The role of individual differences

The present study examined the relationship between physical and psychological well-being, personality characteristics and demographic variables related to motherhood, work and marital status in a sample of 3,723 Dutch women. Analysis revealed several interesting relationships. First, whereas neuroticism was negatively related to both physical and psychological well-being, extraversion was positively related to well-being. Second, a clear positive relationship emerged between work participation and both types of well-being. Results are discussed in terms of the vulnerability stress model.     

Evidence from a homosexual sample for a sex‐specific rival‐oriented mechanism: Jealousy as a function of a rival's physical attractiveness and dominance

Among heterosexual women in particular, a rival's physical attractiveness evokes jealousy, whereas among heterosexual men in particular, a rival's dominance evokes feelings of jealousy. The present study conducted with gay men and lesbian women examined whether these sex‐differentiated responses reflect an evolved sex‐specific rival‐oriented mechanism according to which males and females pay attention to different rival characteristics or an evolved general partner‐oriented mechanism, according to which males and females pay attention to those characteristics that their actual and potential partners find important. In an experiment, using a 2 (Participant Sex) × 2 (Rival Physical Attractiveness) × 2 (Rival Dominance) mixed factor design, homosexual participants were presented with a scenario in which their partners were flirting with an individual of the same sex. Lesbian women, but not gay men, reported more jealousy when they were exposed to a physically attractive rival as compared with a physically unattractive rival. Gay males, but not lesbian women, reported more jealousy when they were exposed to a rival high in dominance as compared with a rival low in dominance, especially when exposed to a physically unattractive rival. In addition, among women high in dominance, a dominant rival evoked relatively less jealousy, and among women high in social comparison orientation, an unattractive rival evoked relatively more jealousy. It is concluded that males and females posses an evolved sex‐specific rival‐oriented mechanism through which they respond more or less automatically to those rival characteristics that have been important in sexual selection in our evolutionary past.     

Sex differences in the events that elicit jealousy among homosexuals

When individuals are asked which event would upset them more—a partner's emotional infidelity or a partner's sexual infidelity—among heterosexuals more men than women select a partner's sexual infidelity as the most distressing event, whereas more women than men select a partner's emotional infidelity as the most upsetting event. Because homosexuals’mating psychology is unlike that of heterosexuals, the present study examined which of these two events is more upsetting in a sample of 237 Dutch homosexuals. In support of our hypothesis it was found that, whereas gay men more often than lesbian women chose a mate's emotional infidelity as the most upsetting event, lesbians more often than gay men chose a mate's sexual infidelity as the most upsetting event. In addition, analyses showed that the effect of participant sex on infidelity choice was mediated by beliefs with regard to the co‐occurrence of sexual and emotional infidelity. Apparently, with respect to choosing the most upsetting type of infidelity of their partner, homosexuals resemble heterosexuals of the opposite sex. Several explanations are discussed for this finding.     

Distress about mating rivals

This research tested the evolutionary psychological hypothesis that men and women would be most distressed about threats from rivals who surpass them on sex‐linked components of mate value. Six predictions were tested in samples from three cultures, the United States (N= 208), the Netherlands (N= 349), and Korea (N= 174). Five predictions were supported in all three cultures. Korean, Dutch, and American men, more than corresponding women, report greater distress when a rival surpasses them on financial prospects, job prospects, and physical strength. Korean, Dutch, and American women, in contrast, report greater distress when a rival surpasses them on facial and bodily attractiveness. The cultures differed on some variables. Korean women and men, for example, differed from Americans and Dutch in reporting more distress over rivals who had better financial prospects, better job prospects, and higher status and prestige. Americans exceeded Koreans in reporting distress when rivals had more attractive faces and bodies, whereas the Dutch exceeded the other cultures in reporting more distress when rivals had a better sense of humor. Discussion focuses on possible proximate psychological mechanisms underlying distress over rivals and the theoretical importance of intrasexual competition.     

Narcissistic Personality Inventory: Structure of the adapted Dutch version

Barelds, D. P. H. & Dijkstra, P. (2009). Narcissistic Personality Inventory: Structure of the adapted Dutch version. Scandinavian Journal of Psychology, 51, 132–138. The present study examined the structure of a Dutch adaptation of the 40‐item Narcissistic Personality Inventory ( Raskin & Terry, 1988 ) in a community sample (n = 460) and a student sample (n = 515). Altering the response format of the NPI to a Likert‐scale had no apparent effect on the responses. Confirmatory factor analyses supported neither the four‐factor structure reported by Emmons (1984) , nor the seven‐factor structure reported by Raskin and Terry (1988) . Instead, exploratory factor analyses supported either a single‐factor solution (general narcissism), or a two‐factor solution (Authority/Power and Self‐Admiration). The validity of the NPI was supported by its relations with sex, age, personality, self‐esteem, shame, guilt and social desirability.
