Sex drive, attachment style, relationship status and previous infidelity as predictors of sex differences in romantic jealousy

Recent research examining sex differences in jealousy suggests that more men than women tend to be distressed by sexual infidelity, and that more women than men tend to be distressed by emotional infidelity. The primary explanation for these findings is that evolution has shaped men’s and women’s responses to enhance their chances of reproductive success. However, within-sex differences are also found in terms of relative level of distress at sexual or emotional infidelity. This study examined the effect of alternative variables, particularly those associated with attachment and sexual motivations, on both between- and within-sex differences in relative distress at sexual and emotional infidelity. A community sample of 437 adults provided data using a self-report questionnaire. The results showed that sex drive was a significant predictor of distress at jealousy for both men and women, while attachment avoidance and previously being the victim of a sexual infidelity were significant predictors for men only, and relationship status was a significant predictor for women only. Overall, these findings support the evolutionary model of jealousy, and suggest that sex-specific evolved psychological mechanisms underpinning jealousy are influenced by attachment and sexual motivations.     

Something's missing: need fulfillment and self-expansion as predictors of susceptibility to infidelity

The present authors investigated whether an individual's motivations that are related to need fulfillment and self-expansion within a romantic relationship can predict self-reported susceptibility to infidelity. A sample of 109 college students (50 men, 59 women) who were in dating relationships completed questionnaires that assessed 5 types of variables of need fulfillment (i.e., intimacy, companionship, sex, security, and emotional involvement), 3 types of self-expansion variables (i.e., self-expansion, inclusion of the other in the self, and potential for self-expansion), and susceptibility to infidelity. As the present authors predicted, both sets of predictors (need fulfillment and self-expansion) significantly contributed to the variance in susceptibility to infidelity. The present findings indicated the possibility that, when a relationship is not able to fulfill needs or provide ample self-expansion for an individual, his or her susceptibility to infidelity increases.     

Marital status as a candidate moderator variable of male-female differences in sexual jealousy: the need for representative population samples

Evolutionary psychological theories predict pronounced and universal male-female differences in sexual jealousy. Recent cross-cultural research, using the forced-choice jealousy items pioneered by Buss, et al., 1992, repeatedly found a large sex differential on these self-report measures: men significantly more often than women choose their mate's imagined sexual infidelity to be more distressing or upsetting to them than an imagined emotional infidelity. However, this body of evidence is solely based on undergraduate samples and does not take into account demographic factors. This study examined male-female differences in sexual jealousy in a community sample (N = 335, Eastern Austria). Within a logistic regression model, with other variables controlled for, marital status was a stronger predictor for sexual jealousy than respondents' sex. Contrary to previous research, the sex differential's effect size was only modest. These findings stress the pitfalls of prematurely generalizing evidence from undergraduate samples to the general population and the need for representative population samples in this research area.     

A prototype analysis of infidelity

The current research tested whether the concept of infidelity is prototypically organized and whether laypeople's conceptualizations of infidelity are consistent with how researchers have operationalized this construct. Across 4 studies, results indicated that infidelity is indeed prototypically organized as individuals are able to list and rate how central certain features are to the infidelity construct. Furthermore, there was evidence that the centrality ratings influenced how individuals processed information in a series of memory tasks and narratives about infidelity experiences. Laypeople are less likely than researchers to consider the presence of particular behaviors (i.e., flirting, kissing, and sexual intercourse) as defining qualities of infidelity. Instead, laypeople focus more on the concealment of behaviors and the resulting emotional fallout from infidelity.     

Gender differences in rival characteristics that evoke jealousy in response to emotional versus sexual infidelity

Previous research has shown that in men jealousy is evoked more by a rival's status‐related characteristics than in women, whereas in women jealousy is evoked more by a rival's physical attractiveness than in men. The present study examined whether the occurrence of this gender difference depends upon the type of infidelity one's partner engages in, i.e., emotional or sexual infidelity, and whether these types of jealousy evoke different emotional responses. An experiment was conducted using hypothetical jealousy situations with a 2 (participant gender: male vs. female) × 2 (rival physical attractiveness: high vs. low) × 2 (rival dominance: high vs. low) × 2 (type of infidelity: sexual vs. emotional) mixed‐factor design. Jealousy evoked by emotional infidelity was primarily characterized by feelings of threat, and jealousy after sexual infidelity was primarily characterized by feelings of betrayal and anger. Following emotional infidelity, in men, a rival's dominance, and in women, a rival's physical attractiveness, evoked feelings of threat but not feelings of anger‐betrayal. In contrast, after sexual infidelity, in men, but not in women, a rival's physical attractiveness evoked feelings of betrayal‐anger but not anxiety or suspicion.     

Pluralistic ignorance and misperception of social norms concerning cheating in dating relationships

Two studies tested the hypothesis that beliefs about infidelity in dating relationships reflect pluralistic ignorance, a misperception in which people mistakenly believe that their own personal attitudes and behavior differ from others' when they do not. Consistent with pluralistic ignorance findings in other domains, undergraduates reported that the average university student (a) saw dating infidelity as more acceptable and (b) engaged in unfaithful acts more frequently than they themselves did. Neither type of infidelity (sexual, emotional, both sexual and emotional, or unspecified; Study 1, N = 176) nor motivated reasoning (i.e., defensiveness; Study 2, N = 359) moderated this pattern of results. Possible sources of misperceived norms concerning fidelity in dating relationships and the implications of such misperceptions are discussed.     

Assessment of factors in marital adjustment

The present study sought to assess important factors in marital adjustment and their interrelatedness. The explored factors were (a) sexual satisfaction and adjustment, (b) verbal and nonverbal communication, and (c) several demographic variables (e.g., age and number of years married). Marital adjustment was found to be significantly related to verbal and nonverbal communication, but not to sexual satisfaction and adjustment. Demographic variables were not found to be related to marital adjustment, but some were significant predictors of verbal and nonverbal communication and sexual satisfaction and adjustment. The implications of these findings for assessment and intervention in marital and sexual counseling and for future research are discussed.     

Same‐sex infidelity in heterosexual romantic relationships: Investigating emotional,relational, and communicative responses

The present study explores emotional, relational, and communicative responses to different‐sex and same‐sex infidelity in heterosexual romantic relationships. Two‐hundred and eighty‐five men and women completed an online survey. Individuals were asked to read a scenario in which an imagined heterosexual partner engages in infidelity with a different‐sex or same‐sex person. Individuals were randomly assigned to one of these two conditions and then asked to complete several measures assessing their imagined emotions, communicative responses, and relational outcomes. Results revealed that both men and women experienced more negative emotional responses to different‐sex infidelity versus same‐sex infidelity. Additionally, men reported more sexual arousal in response to a woman's same‐sex infidelity versus different‐sex infidelity, while women's sexual arousal did not vary across conditions. Lastly, men's communicative responses to jealousy (CRJs) for same‐sex and different‐sex infidelity did not vary, though women reported that they were more likely to respond to same‐sex infidelity than different‐sex infidelity with denial, and more likely to respond to different‐sex than same‐sex infidelity with signs of possession. Several emotional responses to same‐sex infidelity were also found to predict various CRJs. These findings and the implications of the study are discussed.     

Sex Differences in Jealousy: An Evolutionary Perspective on Online Infidelity

This study examined whether sex differences in jealousy would generalize to online infidelity. Based on the evolutionary psychological explanation for sex differences in jealousy (ancestral men's challenge of paternal uncertainty vs. ancestral women's challenge of ensuring paternal investment), we expected that men and women would perceive online infidelity similarly to conventional infidelity. The experimental design was a 2 (Infidelity Context: online or conventional) × 2 (Participant Sex) × 2 (Infidelity Type: emotional vs. sexual) mixed factorial. Participants were 332 (132 male, 200 female) undergraduates who completed a questionnaire assessing their responses to potential infidelity. As predicted, online and conventional infidelity elicited the same sex difference in jealousy. Implications for social scientists who study online behavior are discussed.     

Jealousy and infidelity: The role of gender identity and culture of honour

Abstract

This research is aimed at examining whether gender and the culture of honour were associated with the type of infidelity (sexual or emotional) that is perceived as most disturbing. A total of 748 Spanish university students (336 men and 412 women), answered to six dilemmas which raised the type of infidelity that had greater impact on them (sexual or emotional), a scale of gender identity and a scale of culture of honour. The results showed that both men and women were more affected by emotional infidelity. In addition it was found that the effect of sex on the type of infidelity that stresses the participants more was moderated by sociocultural variables such as the culture of honour, masculinity and femininity.     

Culture and gender differences in romantic jealousy

Jealousy is an intense emotion that is experienced in the context of romantic relationships. Previous research reported gender differences in ratings of jealousy over a sexual versus emotional infidelity. This study explored culture and gender differences in jealousy using a mixed methods survey design. One hundred and forty-five undergraduates from the University of Hawai‘i at Hilo participated. The Horizontal and Vertical Individualism and Collectivism Scale, Self-Report Jealousy Scale, and a modified Emotional and Sexual Jealousy Scale were used for analyses. Two hierarchical multiple regression analyses revealed that gender was a better predictor than culture in jealousy ratings involving an emotional infidelity; but culture was a better predictor for jealousy ratings involving a sexual infidelity. t-Tests also revealed that those who experienced an infidelity in the past reported significantly higher jealousy ratings and that women reported significantly higher jealousy ratings in emotional but not in sexual infidelity than men. The qualitative results revealed four dominant themes related to participant’s causal attributions of jealousy: Infidelity, Expectations of Time and Commitment, Social Media and Self-Esteem. The authors suggest that future research focus on intersexual and intrasexual differences in jealousy, as well the role social media may play in relationship expectations.     

Family-of-Origin,Sexual Attitudes,and Perceptions of Infidelity: A Mediation Analysis

Abstract

The purpose of this study was to examine the influence family of origin and sexual attitudes have on perceptions of infidelity through a mediation analysis to test whether sexual attitudes mediates the relationship between family of origin attitudes and perceptions of infidelity. Results indicated that family of origin attitudes were linked with higher permissive sexual attitudes and lower perceptions of infidelity. Additionally, results indicated an indirect link between family of origin attitudes and perceptions of infidelity through sexual attitudes. These findings align with previous research examining how family of origin influences the occurrence of infidelity and provides insight to helping professionals as they address infidelity in romantic relationships.     

The effects of marriage education for army couples with a history of infidelity

While existing literature has begun to explore risk factors which may predict differential response to marriage education, a history of couple infidelity has not been examined to determine whether infidelity moderates the impacts of marriage education. The current study evaluated self-report marital satisfaction and communication skills in a sample of 662 married Army couples randomly assigned to marriage education (i.e., PREP) or a no-treatment control group and assessed prior to intervention, post intervention, and at 1 year after intervention. Of these, 23.4% couples reported a history of infidelity in their marriage. Multilevel modeling analyses indicated that having a history of infidelity significantly moderated the impact of PREP for marital satisfaction, with a trend for a similar effect on communication skills. However, couples with a history of infidelity assigned to PREP did not reach the same levels of marital satisfaction after intervention seen in the group of couples without infidelity assigned to PREP, although they did show comparable scores on communication skills after intervention. Implications of these findings for relationship education with couples with a history of infidelity are discussed.     

Jealousy,Gender, and Culture of Honor: A Study in Portugal and Brazil

The purpose of this study was to examine whether gender and culture of honor were associated with the type of infidelity (sexual or emotional) that affected our subjects more. Samples of 192 Portuguese university students (119 women and 73 men) and 415 Brazilian university students (214 men and 201 women) participated in this research. Participants responded to six dilemmas reflecting a type of infidelity (sexual or emotional), a gender scale, and a culture of honor scale. The results of both samples are compatible with the cultural theses about jealousy. Both men and women were more affected by emotional infidelity. In addition, it was found that the relationship between the sex of the participants and the type of infidelity that induced stress in them was affected by sociocultural variables, such as culture of honor, masculinity, and femininity. Some differences in the response patterns in the case of an infidelity, in both samples (Portuguese and Brazilian), are shown and discussed.     

EVOLUTIONARY ORIGINS OF SEX DIFFERENCES IN JEALOUSY?

Abstract— Evolutionary psychology has become a popular framework for studying jealousy. Much of this popularity can be attributed to work by Buss and his colleagues showing an apparent relation between an individual's sex and jealousy for certain types of infidelity (i.e., sexual vs emotional) that is consistent with evolutionary theory (Buss, Larsen, Westen. & Semmelrolh, 1992). In two studies, we take issue with these findings and argue that the relation between sex and jealousy reported by Buss and his colleagues is more property explained by considering individuals' beliefs concerning the covariation between sexual and emotional infidelity.     

Childhood abuse in Chinese patients with borderline personality disorder

This study examined (1) the relative prevalence of childhood abuse and other pathological childhood experiences in China reported by outpatients with borderline personality disorder (BPD), with other personality disorders, and without personality disorders; and, (2) whether the primary predictors of BPD in North America are associated with the development of BPD in China. The childhood experiences of 203 outpatients with BPD, 109 outpatients with other personality disorders, and 70 outpatients without Axis II diagnoses were assessed with the Chinese version of the Childhood Experience of Care and Abuse Questionnaire (CECA.Q). Patients with BPD reported significantly more physical, emotional, and sexual abuse than either comparison group. Four types of childhood experiences were significant predictors of BPD: maternal neglect, paternal antipathy, sexual abuse, and maternal physical abuse. The findings suggest that maternal physical abuse is as strong a predictor of BPD in China as sexual abuse, a finding not replicated in North America.     

Maternal psychosocial predictors of pacifier use in a mother-infant interaction task: An observational study from the MPEWS pregnancy cohort

The prevalence of pacifier use is high but when it occurs outside of the recommended sleep context, it becomes more controversial. Using 211 mother-infant dyads recorded as part of the Mercy Pregnancy and Emotional Wellbeing Study, we examined the maternal psychosocial predictors of pacifier use within an interaction task (i.e., ten minutes face-to-face followed by 30-minutes unstructured play). Predictors included maternal emotional availability measured with the Emotional Availability Scales; depression measured by the Structured Clinical Interview for the DSM-IV-TR Clinician Version; and maternal history of childhood trauma measured by the Childhood Trauma Questionnaire. An unadjusted odds ratio demonstrated that women classified as non-emotionally available to their infants were three-and-a-half-times more likely to use a pacifier. Multivariate logistic regression including all maternal psychosocial predictors demonstrated that even when adjusting for cessation of breastfeeding, maternal emotional availability remained the only significant predictor of pacifier use. This is the first time that predictors of pacifier use have been examined with a sample of clinically depressed women, as well as women with childhood trauma history. The results provide preliminary evidence that women who are not emotionally available might be more likely to rely on a pacifier during mother-infant interaction.     

Would Mozambican Women Really “Tolerate” Their Husbands’ Extramarital Sexual Relationships as Socially Recommended?

In the Mozambican socio-cultural context, men’s extramarital sexual relationships are generally deemed acceptable, and women are “recommended” to forgive their husbands’ sexual infidelity. Thus, the purpose of this study was to assess to what extent Mozambican women would forgive their husbands in case of an extramarital sexual relationship. The material consisted of 24 vignettes—each of which contained the story of a husband who was having an extramarital sexual relationship—a question, and an 11-point response scale. Overall, 225 women indicated their willingness to forgive their husbands in case of sexual infidelity, as a function of three factors: the emotional intensity involved in the extramarital sexual relationship, the regret expressed by the husband, and the commitment involved in the relationship/marriage between the husband and his wife. ANOVA results showed that the willingness to forgive depends on the nature of the extramarital relationship and the attitude of the “cheater”: (a) in the case where the extramarital relationship was of a purely sexual type, without involving deep emotions, and when the husband expressed profound regret, the willingness to forgive was high; (b) in the opposite situation, i.e., when the extramarital relationship involved a high level of emotions, and the husband expressed no regret, the forgiveness was low. Older participants had relatively high rates of forgiveness compared to younger ones. These findings corroborate earlier studies showing that, for females, emotional infidelity was much more distressful than purely sexual infidelity, and corroborate studies showing that Mozambicans tend to forgive offenders when they express regret.     

Predictors of PTSD Improvement with Cognitive/Exposure Group Interventions in Operation Enduring Freedom/Operation Iraqi Freedom Female Veterans

Predictors of successful PTSD outcome have been examined through individually delivered treatments. We examined predictors using a group protocol with cognitive, exposure, and skills modules. Assessments included self-report and interview (CAPS, SCID-I/II) measures at baseline, post, and six months; treatment was a 16-week, three-member group for 32 OEF/OIF women Veterans. A regression analysis showed major depressive disorder and no baseline psychiatric medication predicted PTSD improvement. PTSD improvement predicted fewer outpatient medical visits at follow-up. The results supported past research and challenged other findings (e.g., sexual assault predicts less improvement). An additional unique contribution was examining predictors in a group treatment format.
