Solidarity and Prosocial Behavior
The topic of prosocial behavior (e.g. fairness, solidarity, and altruism) has recently shifted back into the center of attention in a variety of disciplines, ranging from economics across sociology and psychology towards biology. It is now a well-accepted fact in all human sciences that human behavior is not always governed by egotism and selfish motives. Unfortunately, this does not explain why humans also act blatantly selfish and are blind to …

When It Is Better to Give Than to Receive
The authors examined esteem enhancement theory and equity theory in explaining the long-term health status of men (n = 178) and women (n = 575). Baseline characteristics were measured in 1990-1993, intimate reciprocity in 1993, and recorded sickness absences for a 9-year period during 1993-2001. Among women, giving more support than receiving in intimate relationships positively affected subsequent health status, as indicated by fewer sickness ab…
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 emotiona…

Age and Gender Differences in Mate Selection Criteria for Various Involvement Levels
The present study investigated mate preferences for five different levels of relationship involvement—marriage, serious relationship, falling in love, casual sex, and sexual fantasies–among individuals of 20, 30, 40, 50, and 60 years of age. Consistent with an evolutionary perspective, men preferred mates who were higher in physical attractiveness than themselves, whereas women preferred mates who were higher in income, education, self–confidence…
Caregiver burnout among intimate partners of patients with a severe illness
In the present study, caregiver burnout among the intimate partners of 106 cancer patients and 88 patients with multiple sclerosis was assessed. This study examined how burnout is related to marital quality and perceptions of inequity in the relationship. LISREL analyses showed that higher perceptions of inequity are strongly associated with higher emotional exhaustion and depersonalization, and lower feelings of personal accomplishment. Intimate…
Sex differences in the jealousy‐evoking effect of rival characteristics
Four studies examined sex differences in the jealousy‐evoking nature of rival characteristics. Study 1, among 130 undergraduates, made an inventory of all relevant rival characteristics that were spontaneously mentioned when asked about a rival to whom one's partner might feel attracted. On the basis of these findings, in Study 2, among 240 undergraduates, a questionnaire was constructed, containing 56 rival characteristics. A factor analysis dis…

Neuroticism and Social Comparison Orientation as Moderators of Affective Responses to Social Comparison at Work
In a study among 72 nurses, the affective consequences of social comparison were examined and related to neuroticism (N) and to social comparison orientation (SCO). Participants were confronted with a bogus interview with an upward versus a downward comparison target. Positive affect and identification were higher, and negative affect was lower, in the upward than in the downward comparison condition. Independent of their SCO, the higher individu…
Justice of give‐and‐take in the intimate relationship
This study examined to what extent couples facing cancer ( N = 55) and healthy couples ( N = 74) perceived various distributions of give‐and‐take to be just or fair when occurring within a relationship of a cancer patient and his or her partner. Participants read one of three versions of a bogus interview with a couple facing cancer. In these scenarios, both partners were either equally well‐off in terms of give‐and‐take or one partner was better…
Evidence from a homosexual sample for a sex‐specific rival‐oriented mechanism
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 evol…
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 e…

Are Equity Concerns Important in the Intimate Relationship When One Partner of a Couple Has Cancer
Roeline G. Kuijer, Bram P. Buunk, Jan F. Ybema, Are Equity Concerns Important in the Intimate Relationship When One Partner of a Couple Has Cancer?, Social Psychology Quarterly, Vol. 64, No. 3 (Sep., 2001), pp. 267-282
When individuals dislike exposure to an actively coping role model
A total of 122 individuals, including those clinically depressed and nondepressed, were exposed to a description of a target who overcame his or her depression either through active coping (high effort), or seemingly by itself (low effort). Participants first completed the Beck Depression Inventory and the Iowa–Netherlands Comparison Orientation Measure. As predicted, among the nondepressed, with increasing levels of social comparison orientation…
The affective consequences of social comparison as related to professional burnout and social comparison orientation
In a study among sociotherapists, the affective consequences of social comparison were examined and related to professional burnout and to individual differences in social comparison orientation. Participants were confronted with a bogus interview with an upward versus a downward comparison target. Upward comparison generated more positive and less negative affect than did downward comparison. Increasing levels of burnout were accompanied by less…
New directions in social comparison research
This article notices that social comparison theory has developed from being a focused theoretical statement on the use of others for self‐evaluation into a lively and varied area of research encompassing many different paradigms, approaches and applications. A recent ‘renaissance’ in social comparison theory is described in which links were established with social comparison work from before Festinger's ( 1954 ) classic paper, and in which variou…
Enhancing Satisfaction through Downward Comparison
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, r…
Reciprocity in Interpersonal Relationships
Based on an evolutionary analysis of reciprocal altruism, it is argued that humans have developed innate mechanisms to expect reciprocity in interpersonal relationships and that a lack of reciprocity is accompanied by negative affect. The authors present an overview of their own research programme documenting the importance of reciprocity in a wide variety of relationships, including marital relationships, lesbian relationships, extradyadic sexua…
Employees' reactions to problematic events
A refined exit, voice, loyalty, and neglect (EVLN) typology (Farrell, 1983) was examined. It was argued that the category of voice responses, that is, attempts to improve the situation, should be divided into two forms: considerate voice and aggressive voice. Considerate voice consists of attempts to solve the problem taking into account one's own concerns as well as those of the organization, and aggressive voice consists of efforts to win, with…
Commitment Processes in Close Relationships
This article employs interdependence theory as a means of understanding how and why some relationships survive difficult times whereas other promising relationships end. Interdependence theory makes important distinctions between satisfaction and dependence. These distinctions are extended in the investment model, a theory of the process by which individuals become dependent on and committed to their relationships. The investment model suggests t…
Individual differences in social comparison
Development and validation of a measure of individual differences in social comparison orientation (the Iowa-Netherlands Comparison Orientation Measure [INCOM]) are described.Assuming that the tendency toward social comparison is universal, the scale was constructed so as to be appropriate to and comparable in 2 cultures: American and Dutch.It was then administered to several thousand people in each country.Analyses of these data are presented in…
The affective consequences of social comparison
Research on social comparison processes has assumed that a comparison in a given direction (upward or downward) will lead to a particular affective reaction. In contrast, the present two studies proposed and found that a comparison can produce either positive or negative feelings about oneself, independent of its direction. Several factors moderated the tendency to derive positive or negative affect from upward and downward comparisons. In Study …
A longitudinal study of equity and satisfaction in intimate relationships
This longitudinal study was aimed at illuminating some fundamental problems with respect to the application of equity theory in intimate relationships. First the relationship between perceived equity and satisfaction was tested, and next it was ascertained whether inequity produces dissatisfaction or vice versa. A second issue addressed in the present study was whether global assessments of equity represent some type of calculation made by the su…
Equity, Normative Disapproval and Extramarital Relationships
This study examined the extent to which inequity, normative disapproval and marital dissatisfaction were related to involvement in extramarital sexual relationships. The study was conducted among 82 married men and 132 married women with a mean age of 41. Of the sample, 30 percent had been involved in extramarital relationships. The results showed that among men as well as women, normative disapproval, and to a lesser extent, relational dissatisf…

Among women, giving more support than receiving in intimate relationships positively affected subsequent health status, as indicated by fewer sickness ab…
Sex, Self-Esteem, Dependency and Extradyadic Sexual Experience as Related to Jealousy Responses
A study of a heterogeneous sample of 250 mostly married individuals examined the impact of sex, self-esteem, emotional dependency and extradyadic sexual experience upon betrayal-anger, disappointment and self-doubt as responses to extradyadic sexual behavior of the partner. Women scored higher in self-doubt and disappointment than men, but not in betrayal-anger. When the other variables were included as independent variables, women showed still m…
Extradyadic sex
The willingness to engage in extradyadic sexual behavior was examined in relation to attitudes, descriptive norms (what others do or are willing to do), and injunctive norms (what others think one should do). Although in research on attitude‐behavior relationships injunctive norms are usually assessed, we assumed that descriptive norms would be at least as important a predictor of extradyadic sex. With an interval of 15 years, we questioned two s…

Enhancing Satisfaction through Downward Comparison
When better-than-others compare upward
Social comparison theory has linked improved performance to both the tendency to compare with others who are performing well and the tendency to view the self as better than others. However, little research has investigated the effects of either variable outside of a controlled laboratory environment, Moreover, there is reason to believe that the 2 tendencies would be in opposition to one another, because people who compare upward might subsequen…
Equity Perceptions and Marital Satisfaction in Former and Current Marriage
A study among 290 remarried individuals examined equity perceptions in the former and the current marriage. The results showed that equity in the former and the current marriage were not related to each other. In general, respondents perceived much more inequity in the former than in the current marriage, and this was especially true for women. Men felt on average deprived in their former marriage, and overbenefited in their current marriage, whe…
Social comparison, equality, and relationship satisfaction
Perceived reciprocity, social support, and stress at work
Perceived reciprocity regarding support in relationships at work was examined among employees of a psychiatric hospital (Study 1) and in a study of employees of the Dutch National Railway Company (Study 2). Relationships with colleagues were more often perceived as reciprocal than relationships with superiors, and in relationships with superiors individuals more often fell overbenefited. Lack of reciprocity-being underbenefited or being overbenef…
Closeness, Autonomy, Equity, and Relationship Satisfaction in Lesbian Couples
It is often assumed that in lesbian relationships a high degree of closeness is reached at the expense of autonomy of the partners. The present study among 119 Dutch lesbian couples examined the effect on relational satisfaction of two dimensions of closeness, emotional dependency and intimacy, and of autonomy and equity. The women in this study were generally open about their lesbian relationship, and reactions of the social environment were mos…
Cross‐cultural differences in the elicitation of sexual jealousy
This paper focuses on cross‐cultural differences in sexual jealousy. It is assumed that cultures differ (a) in the incidence of sexual jealousy, (b) in the range of acceptable strategies for coping with a jealousy situation, and (c) in the behavior evoking sexual jealousy. We addressed the last aspect. Subjects were 2,079 students from seven industrialized nations: Hungary, Ireland, Mexico, the Netherlands, the Soviet Union, the United States, an…

Social comparison preferences among cancer patients as related to neuroticism and social comparison orientation
Effects of neuroticism and social comparison orientation on social comparison among cancer patients were examined. A computer program that enabled patients to access information about fellow patients' disease-related experiences was developed. Patients selected more interviews concerning more as compared to less fortunate others, spent more time reading, and showed more favorable reactions to such information. Individuals with a strong comparison…

The affective consequences of social comparison as related to professional burnout and social comparison orientation
In a study among sociotherapists, the affective consequences of social comparison were examined and related to professional burnout and to individual differences in social comparison orientation. Participants were confronted with a bogus interview with an upward versus a downward comparison target. Upward comparison generated more positive and less negative affect than did downward comparison. Increasing levels of burnout were accompanied by less…
Aiming at the top? Upward social comparison of abilities after failure
This study examined the effects of feedback on a task on information seeking and partner preferences as forms of social comparison. It was predicted that subjects who experienced failure and perceived control over future performance would, for reasons of self‐improvement, choose more strongly upward a comparison other than subjects who experienced success or perceived no control. In the experiment, 121 college students were given either failure, …
Conflict in Intimate vs Non-Intimate Relationships
An experiment was conducted to explore whether bias in self-other judgments pertains to conflict in intimate relationships and is overruled by gender role stereotypes in non-intimate relationships between males and females. It was predicted that when the opponent was one's intimate partner, both male and female participants would rate themselves as intending more cooperative and less competitive behavior than their partner. In non-intimate relati…
Sex-Role Attitudes, Social Comparison, and Satisfaction with Relationships
In the present study, we were interested in whether satisfaction with relationships is related more strongly to equity comparison with the partner or with a reference group. We tested two non-exclusive hypotheses derived from social comparison theory. First, we expected that the association between satisfaction and comparison with the partner would be stronger among individuals with egalitarian sex-role beliefs, whereas among individuals adhering…
Knowledge, Utility and Sense of Efficacy as Determinants of Environmentally Responsible Behavior
A cognitively oriented approach was chosen for the prediction of behavior. The degree in which environmentally responsible behavior could be predicted from utility, knowledge, and sense of efficacy was investigated in a sample of 204 respondents. It was shown that knowledge was the most important determining factor, although only 25% of the variance could be explained
Jealousy as Related to Attributions for the Partner's Behavior
This study addressed itself to the causes attributed to, extramarital sexual involvement, and the association of these causes with sexual jealousy. The results did not show any significant actor-observer difference; in general both spouses attributed their own and their partners' affairs to similar causes. Most frequently mentioned were situational factors and a need for novelty and excitement. Only one sex difference did show up: a need for sexu…
Romantic Jealousy and Romantic Envy
Factor analyses and Procrustes rotations of the responses of 1194 female and 877 male university students in seven countries to a 69-item Likert-type questionnaire revealed cross-cultural commonalities and differences for romantic jealousy and romantic envy. However, when mean ratings of the questionnaire items were categorized as indicating agreement or disagreement with the items, the evidence for cross-cultural invariance of jealousy and envy …
Cross‐cultural differences in the elicitation of sexual jealousy
This paper focuses on cross‐cultural differences in sexual jealousy. It is assumed that cultures differ (a) in the incidence of sexual jealousy, (b) in the range of acceptable strategies for coping with a jealousy situation, and (c) in the behavior evoking sexual jealousy.

Attitudes Towards Nudist and Public Beaches
Attitudes towards recreation in bathing attire and nudist beach recreation were studied using a semantic differential encompassing 17 concepts. Respondents were 333 public beach visitors (166 males and 167 females) and 353 visitors to nudist beaches (187 males and 167 females). Two specific hypotheses were tested. (1) On the basis of cognitive dissonance theory it was predicted that visitors to nudist beaches would reduce dissonance by emphasizin…

Referential Comparisons, Relational Comparisons, and Exchange Orientation
Employing a sample of 214 individuals, this study showed that most individuals felt the input/outcome ratio in their marital relationship was better than that of most same-sex others (referential comparisons) but equal to that of their spouse (relational comparisons). Perceptions of superiority in referential comparisons and of equity in relational comparisons were accompanied by the highest level of marital satisfaction. However, further analyse…

Commitment Processes in Close Relationships
This article employs interdependence theory as a means of understanding how and why some relationships survive difficult times whereas other promising relationships end. Interdependence theory makes important distinctions between satisfaction and dependence. These distinctions are extended in the investment model, a theory of the process by which individuals become dependent on and committed to their relationships. The investment model suggests t…
Social Comparison Processes under Stress
After outlining the history of social comparison theory as far as it is relevant to stress, this chapter substantiates and expands the model of Taylor and Lobel (1989) by presenting evidence from classic and recent research, particularly survey research conducted by the author and his colleagues in divergent populations under stress. These populations include individuals with marital problems, nurses, and persons diagnosed as unfit to work. Three…
Social interactions, stressful events and negative affect at work
In the present study a daily event‐recording method, the DIRO (Daily Interaction Record in Organizations), was employed for assessing social interactions, stressful events and negative affect at work. Forty‐one secretaries filled out the records during the course of a week. This made it possible to consider both between‐and within‐subject effects of social interactions. The results showed that the social interactions of secretaries were character…

Women scored higher in self-doubt and disappointment than men, but not in betrayal-anger. When the other variables were included as independent variables, women showed still m…
Sex Differences in Jealousy in Evolutionary and Cultural Perspective
As predicted by models derived from evolutionary psychology, men within the United States have been shown to exhibit greater psychological and physiological distress to sexual than to emotional infidelity of their partner, and women have been shown to exhibit more distress to emotional than to sexual infidelity Because cross-cultural tests are critical for evolutionary hypotheses, we examined these sex differences in three parallel studies conduc…

Correlates of Self-Reported Adult Attachment Styles in a Dutch Sample of Married Men and Women
The relationships between attachment style, recollections of the family of origin, working model of self and others and current relational satisfaction were examined in a Dutch sample of married subjects from the general community. Measures were adapted from those developed by Hazan & Shaver (1987). Results generally corroborated the Hazan & Shaver (1987) analyses: subjects endorsing the avoidant and anxious ambivalent styles reported more advers…

Responses to unprotected extradyadic sex by one's partner
With a sample of 251 Dutch adults, many of whom had been involved in extradyadic sex, we examined three responses to unprotected extradyadic sex by the partner: angry retreat (anger, upset, and inclination to leave the partner), accommodation (open communication aimed at preserving the relationship), and assertiveness (demanding precautionary measures from the partner). Hypotheses were based upon interdependence theory and equity theory. A factor…
