The social exchange theory postulates the satisfaction with the relationship to be lower for individuals whose costs and investments are higher than the rewards gained from the relationship. Rusbult’s investment model of close relationships predicts that the greater the investment individuals make in the relationship, the less likely they are to leave, even if their satisfaction is low and other alternatives look promising. The aim of this study was to examine the role of the perceived distribution of housework, financial investments and decision making between partners in explaining both partners' perception of their relationship. The sample consisted of 418 married and cohabiting couples. Both partners independently evaluated the quality and stability of their relationship and their satisfaction with it. They also assessed the distribution of housework, financial investments and decision making in their relationship, as well as their satisfaction with that distribution. The highest satisfaction with the distribution of financial and decision making investments for both sexes was the one in which both partners contributed equally. As for the distribution of housework, while men are equally satisfied with any kind of distribution, women who perceive that they do most of the housework are the least satisfied. The satisfaction with the distribution of investments proved to be more important for the evaluation of the relationship than the actual distribution of investments. The satisfaction with the distribution of investments contributed to the relationship quality and satisfaction with it more than to the relationship stability. These results support both the social exchange theory and the equity theory. Keywords: relationship quality, relationship stability, satisfaction with a relationship, distribution of investments Introduction One of the most frequently used theories in addressing the question of how love develops and how it is maintained is the social exchange theory, which hypothesizes that relationships operate on an economic model of costs and benefits (Blau, 1964; Kelley & Thibaut, 1978). The social exchange theory states that the way people feel about their relationship will depend on their perception of the rewards they receive from the relationship and the costs they have, as well as on their comparison level – their expectations about the rate of rewards and costs they are likely to receive in a particular relationship. If people perceive their relationship as gratifying and of high quality, they will be satisfied with it. Rusbult (1983) has found that during the first three months of the relationship college-age dating couples focused much more on rewards than on costs, and the perception of rewards continued to be important further on. The perception and importance of costs came into play a few months into the relationship, and costs became increasingly important over time. Satisfaction with the relationship decreased significantly for those who reported their costs and investments to be higher than the rewards gained from the relationship. During the past few decades the research has shown extensive support for the social exchange theory in intimate relationships (e.g., Lin & Rusbult, 1995; Rusbult & Van Lange, 1996). However, although the perceived costs/rewards rate, moderated by the comparison level, proved to be a significant predictor of an individual’s satisfaction with a relationship, these variables were not sufficient to predict whether a person would stay in a relationship or end it. Recognizing that the satisfaction with a relationship and the relationship stability might be separate issues, another model was advanced from the social exchange theory – The Investment Model proposed by Caryl Rusbult (1980, 1983). According to the investment model, costs/rewards rate and the comparison level influence the satisfaction with the relationship, while the relationship stability could best be predicted on the basis of both partners’ level of commitment, representing their long-term orientation toward a relationship and the desire to maintain it. There are three independent factors that determine the level of commitment: satisfaction, investments, and quality of alternatives. Research has demonstrated that the level of commitment was associated with the individual’s satisfaction with the relationship (e.g., Bui, Peplau, & Hill, 1996; Rusbult, 1980). However, although unsatisfied, people sometimes want their relationships to continue. According to the investment model, the second important predictor of the commitment is the quality of alternatives – subjective assessment of rewards and costs that could be obtained outside the current relationship. Thirdly, the commitment is also affected by investments of resources such as time, effort or money that the individual has already contributed to the relationship and would lose if the relationship were to end. Rusbult’s investment model of close relationships predicts that the greater the investment individuals make in the relationship, the less likely they are to leave, even if their satisfaction is low and other alternatives look promising. Rusbult’s model proved to be powerful in predicting commitment and persistence across different types of romantic relationships - dating relationships (e.g., Bui, Peplau, & Hill, 1996; Lin & Rusbult, 1995), marital and cohabiting heterosexual relationships (e.g. Rusbult, Johnson, & Morrow, 1986; Impett, Beals, & Peplau, 2001-2002), lesbian and gay relationships (e.g. Beals, Impett, & Peplau, 2002; Duffy & Rusbult, 1986) – as well as in friendships, formal and informal groups, and organizational settings (for review see Rusbult, Martz, & Agnew, 1998). Nevertheless, most of these studies have been carried out in North American society and culture, which differs from the Croatian in many ways, among others in economic orientation. In other words – an “economic” model of close relationships explains relationship stability in economy-oriented culture. The inevitable question is – do people in other parts of the world behave and think about their relationships the same way? In order to prove its generalizability and cross-cultural validity, the investment model has to be tested on romantic and other close relationships outside the United States. Caryl Rusbult (1983) defines investment as anything people have put into a relationship that will be lost if they leave it. That could mean tangible things, such as financial resources and possessions, or intangible, such as the time or physical and emotional energy spent. Since the investment model was proposed, different authors have operationalized the investment in many different ways. Some of them registered objective indicators such as a house, a car, a joint bank account, number of children etc., but generally the level of investment was measured by asking people to consider and assess how much they had invested in their relationship. In the Investment Model Scale, designed by Rusbult, Martz, and Agnew (1998), the investment is addressed either as a sign of how unbreakable connection with the partner and his/her world is established (e.g., “Many aspects of my life have become linked to my partner…”, “My partner and I share many memories”, “My sense of personal identity is linked to my partner and our relationship”) or people are directly asked whether they feel that they have invested a great deal in their relationship (without specifying what is meant by that). There are many advantages of such an operationalization of investment. These global measures are suitable for researching various types of relationships and allow their comparison. The problem with global self-evaluation scales lies in the fact that people give their answers taking into consideration many different facets of a given variable and base the assessed level on those facets, yet the researcher does not know which facets they were considering. If we don’t know which particular, everyday things people have in mind when thinking about their investments in a relationship, little can be done to help people in maintaining or improving that relationship. Therefore, in this research we have addressed the issue of investment from another perspective –asking the participants about the distribution of the investments of particular resources such as money, effort, and time, between them and their partners, in long-term intimate relationships. We were interested in three kinds of investments or contributions to relationship - financial investments, housework and child care, and involvement in decision making. By doing this, we have found ourselves on the ground of equity theory (Homans, 1961; Walster, Walster, & Berscheid, 1978), whose proponents have criticized the social exchange theory for ignoring the variable of fairness in a relationship. They have argued that people were concerned about equity in their relationship and that they would be happiest in a relationship in which the rewards and costs they experience and the contributions they make to the relationship are roughly equal to their partner’s. The strength of the social exchange theory is that it has clearly distinguished satisfaction with the relationship from the relationship stability, while its weakness is that it does not address how an initially stable relationship might become unstable over time. Furthermore, the conceptualization of costs and rewards lacks a temporal perspective. The equity theory offers a reasonable explanation of how an initially well meaning and willing investment may after some time be seen as a cost, and affects both satisfaction with the relationship and its stability. In long-term close relationships, like close friendship, family and marriage/cohabitation, interactions between individuals are not as much governed by equity concerns compared to interactions between new acquaintances, in the so called exchange relationships. In these communal relationships people give because of a desire to respond to the other’s needs, regardless of whether they are paid back (Mills & Clark, 1982, 2001). However, that does not mean that people in close romantic relationships are unconcerned with equity. It has been shown that partners feel distressed if they believe their intimate relationship is inequitable (e.g., Canary & Stafford, 2001). They simply do not bother with taking care of what constitutes equity at any given time – they believe that things will eventually balance out over time. But, when time goes by and this does not happen, they begin to feel the imbalance and become unsatisfied with the relationship. Research conducted so far in the area of close relationships used different dependent variables when evaluating relationships, which makes it difficult to compare the results and come to a general conclusion about the true predictors of a good relationship. While in some research the satisfaction with the relationship was used as a criterion of a good relationship, others used the perceived relationship quality. As already mentioned, the relationship stability is a conceptually different construct from the subjective evaluation of a relationship, so that the predictors of the relationship stability could differ from those of the relationship quality and satisfaction with the relationship. We decided to include all three criteria in order to enable the comparison of our results with the results from previous studies, as well as to investigate the relations among these three criteria. According to the Rusbult’s model, it could be expected that the perceived relationship quality and satisfaction with a relationship will be highly positively correlated, while both these variables will be moderately correlated with the stability of a relationship. The aim of this study was to examine the role of the perceived distribution of housework, financial investments and decision making between partners in explaining both partners' perception of their relationship. More specifically, the first research problem was to explore the impact of sex, education, and the distribution of investments in a relationship (financial investments, housework and child care, involvement in the decision making) on the individual’s satisfaction with such a distribution. The satisfaction with the distribution of investments could be moderated with one’s expectations, and therefore the participant’s sex and educational level have to be taken into account in these analyses. As proposed by the equity theory, it can be assumed that the equal distribution of the investments between partners will be the most satisfying one. The second research problem was to determine whether the distribution of the investments in a relationship and partners' satisfaction with such a distribution were significant predictors of the perceived relationship quality, satisfaction, and stability. According to the social exchange theory, which emphasizes the costs/rewards comparison level, we assumed that the satisfaction with the distribution of investments would be more important than the distribution of investments itself for predicting the aforementioned criteria. Furthermore, in line with the Rusbult’s investment model, these predictors will be more important for explaining the relationship quality and satisfaction with it, than for the relationship stability.
The research was carried out as a part of the 15th Psychological Summer School organized by the Department of Psychology, University of Zagreb Faculty of Humanities and Social Sciences. The data were collected during the two-month period in the spring of 2005. The research was carried out on a convenience sample comprising 418 married and cohabiting heterosexual couples from three Croatian regions (Zagreb, Osijek and Split) who satisfied the following criteria: living together for at least one year (thus ensuring they had enough experience concerning the relevant investment variables), and financial independence, i.e., at least one partner had to be employed (to exclude young couples living together and being financially supported by their parents, which would make the issue of financial investments irrelevant for them). The age of male participants ranged from 20 to 79 years, showing a bimodal distribution: 35.2% participants in the range from 45 to 55 years, and 33.5% in the range from 25 to 35 years of age. The age of female participants ranged from 18 to 75 years, showing a similar bimodal distribution: 45.1% in the range from 41 to 55, and 28.2% from 23 to 31 years of age. Nearly half of the participants have finished high school (50.03% males and 48.2% females), a similar proportion of them had a university diploma (46.0% males and 44.7% females), and 3.3% of men and 6% of women had a Master or PhD degree. The rate of employment was the same for both men and women - 76%. Both partners independently and anonymously evaluated their investments in the relationship, their satisfaction with the distribution of investments and their relationship on a series of scales. The researcher (one of the authors or a psychology student) was present while both partners were filling out the questionnaires, thus ensuring their independent responding to the questions.
The investments in the relationship were divided into following groups: a) financial investments (the costs of house-rent, insurance, bills, groceries, house and car maintenance, clothes, children's activities, summer/winter vacations); b) investments in housework (cooking, laundry, doing dishes, house repairs, vacuuming and dusting, washing windows and floors, taking care of children, taking care of pets, cleaning the bathroom, gardening, car repairs); and c) investment in decision making (choosing a car, choosing a house/apartment, life insurance, decisions about the weekly amount for food, vacations, free time, friends, children). For each investment from all three groups both partners had to choose the option that best describes the distribution of that investment in their relationship: mostly I, equally/together, mostly partner (3 points, 2 points and 1 point, respectively). The result is formed as the total sum of all points for a group of investments divided by the number of items. Higher result thus indicates a higher personal investment in a relationship, in terms of financing, housework, and responsibility for relevant decisions. The Cronbach alpha coefficients were the lowest for the responsibility for relevant decisions (α=.52 for women and α=.65 for men), which was expected considering the intentional heterogeneity of items comprising this scale. The coefficients for decision making (α=.73 for women and α=.61 for men) and financial investments (α=.86 for women and α=.91 for men) were somewhat higher. For each category of investments the participants also assessed their satisfaction with the distribution of those investments on a 7-point scale (1= completely unsatisfied; 7= completely satisfied).
The quality of the relationship was measured by the Quality of marriage index (Norton, 1983), comprising six items. On five of the items participants expressed their (dis)agreement on the 7-point scale (1= completely disagree; 7 = completely agree; e.g., "We have a good relationship."), while on the sixth item they had to asses their happiness in the current relationship on a 10-point scale (1=very unhappy; 10 = very happy; "In general, how happy are you in the relationship with your partner?"). The total range of this measure is 6 to 45, with higher values meaning higher relationship quality. The Cronbach alpha coefficients on male and female subsamples were α=.96 and α=.97, respectively. The stability of the relationship was in fact defined as its opposite pole, i.e. the relationship instability. It was operationalized as the linear combination of three measures: (a) a potential for divorce (Booth, Johnson & Edvards, 1983; – 3 items, e.g., "In the last year, have you been seriously thinking about breaking up your relationship/marriage?", where "yes" was scored with 3 points and "no" with 1 point), (b) perception of the relationship prospects (measured by one item from the DAS; Spanier, 1976 - where participants asses the future of their relationship and their willingness to put an additional effort into maintaining the relationship on a 3-point scale, from "wanting the relationship to succeed at any cost" – 1 point, to "feeling that the relationship can never succeed" – 3 points), and (c) considering alternatives (one item from Stanley & Markman, 1992 – where participants were asked how often they imagined being in a relationship/marriage with someone else: "almost never" – 1 point, "sometimes" – 2 points, "frequently" – 3 points). The total range of this measure is 5 to 15, with higher values meaning higher instability. The Cronbach alpha coefficients on male and female subsamples were α=.76 and α=.75, respectively.
A significant difference between the results of men and women was found on all three dependent variables. Men are more satisfied than women with their relationships, find them of higher quality than women do, and also perceive their relationships as more stable than women do. Table 1 about here One of the aims of this study was to investigate the relations among different dependent variables used in the research of close relationships. Due to the significant sex differences we conducted separate analyses for men and women, but no sex differences in the relations among different dependent variables were found. Pearson’s correlation coefficients between the perceived relationship quality and the satisfaction with the relationship were r(396)=.83, p<.001 for men and r(389)=.80, p<.001 for women. Pearson’s r between relationship stability and satisfaction with a relationship was r(393)=.57, p<.001 for men, r(402)=.56, p<.001 for women, and between relationship stability and relationship quality r(383)=.58, p<.001 for men, r(381)=.56, p<.001 for women. Distribution of investments and satisfaction with itIn order to determine whether the ratio of an individual’s and his/her partner’s investments in a relationship affects the satisfaction with the distribution of such investments, we asked each participant to describe the distribution of investments (financial investments, housework and child care, and involvement in decision making) between self and the partner. According to their answers for each group of investments, we divided them in three groups: 1. higher personal investment, 2. equal investment of both partners, 3. higher partner’s investment, and examined the differences among these groups in satisfaction with the distribution of the investments between partners. As the participant’s sex and educational level were expected to be important moderators of this satisfaction, these two variables have also been included. Therefore, three 3x2x2 analyses of variance (one for each dependent variable), with the distribution of investments (higher than partner’s/equal/lower than partner’s), sex, and education level (high school/academic education) as independent variables and satisfaction with distributions of investments as dependent variables were conducted. Means and standard deviations are shown in Table 2. Table 2 around here
As can be seen in Table 3, ANOVA showed significant main effects of distribution of financial investments, sex and education, as well as significant interactions of distribution of financial investments with both sex and education. These effects are shown in Figures 1 and 2. Post-hoc Scheffé tests revealed that participants were the most satisfied when the distribution of investments was equal, while there was no difference in satisfaction between those who perceived that their partners invested more and those who perceived that they themselves invested more. The interaction of sex and distribution of financial investments showed that there were no sex differences in satisfaction when distribution was either equal, or when one perceived that the other partner contributed more, but the women who perceived that they contributed more were less satisfied than men who perceived that they contributed more. Furthermore, the interaction of education and distribution of financial investments showed that the difference in satisfaction between participants of different education levels emerged only when one partner perceived that s/he contributed more: in that case, the participants with a high-school education were less satisfied with such a distribution than participants with an academic education. Table 3 around here Figures 1 and 2 around here
ANOVA showed significant main effect of the distribution of housework and child care and a significant sex x distribution of housework and child care interaction (Table 3). Post hoc Scheffé tests for the distribution of housework showed that participants with higher personal investments were the least satisfied, while there were no differences between those who perceived that partner invested more and those who perceived the distribution of investments being equal. However, there was a significant interaction between sex and housework distribution (Figure 3). Women who perceived that they did most of the housework were the least satisfied, while for men the perception of distribution of housework did not influence their satisfaction with such a distribution. Figure 3 around here
ANOVA showed significant main effect of the distribution of decision making only (Table 3). Similarly to the results obtained for financial investments, post hoc Scheffé tests revealed that participants were the most satisfied with decision making if both partners contributed equally, while there were no differences between those whose partners made more decisions and those who made most decisions themselves. Distribution of investments and satisfaction with it as predictors of relationship quality, stability, and satisfaction We were also interested in correlations between each of the three measures of relationship assessment and the distribution of each of the three types of investments in the relationship (financial, housework, and decision making), as well as with the satisfaction with such a distribution of investments. The results (Table 4) show that satisfaction with a relationship, relationship quality and relationship (in)stability significantly correlate only with satisfaction with the distribution of investments and not with the distribution of investments itself. The only exception is the distribution of the housework, where satisfaction with a relationship and relationship quality are negatively correlated with the distribution of investments, but only for the female sample. Women who are engaged in the housework more than their partners are less satisfied with their relationship and perceive it of less quality. If we compare the correlation coefficients across the three types of investment, it can be seen that satisfaction with the distribution of responsibility in decision making has the highest correlations with the dependent variables, while satisfaction with the distribution of housework and financing only moderately correlates with the dependent variables. Moreover, the correlations between dependent variables and satisfaction with the distribution of investments are somewhat higher for housework than for financing, especially for women. The satisfaction with a relationship shows the highest correlations with satisfaction with the distribution of investments for all three types of investment, closely followed by the relationship quality, while the relationship stability is only weakly correlated with satisfaction with the distribution of investments.
The second research problem of this study was to determine the contribution of the distribution of different types of investments and satisfaction with the distributions of those investments to the explanation of each partner's satisfaction with the relationship, relationship quality and stability. Therefore, we conducted several two-step hierarchic regression analyses. The first block of variables comprised the individual’s contribution to three types of investments (financial, housework, and decision making). In the second step, the individual satisfaction with the distribution of each type of investment was entered. Three regression analyses were conducted separately for men and women – one for each criterion: satisfaction with the relationship, relationship quality, and relationship stability. The results are presented in Tables 5 and 6. Tables 5 and 6 around here The results of regression analyses are slightly different for men and women, mainly in the first step. For women, the small but significant variance of the satisfaction with the relationship and the relationship quality can be explained with the actual distribution of investments, or, more specifically, with the distribution of the housework. Significant beta predictors show that the more women invest in the housework and childcare in comparison to their partners, the less they are satisfied with the relationship and they perceive the relationship as of lower quality. For men, the actual distribution of investments does not affect the perception of the relationship. The second step of the regression analyses shows similar results for both sexes. None of the actual distributions of investments has significant effect on the perception of the relationship, while the satisfaction with the distribution of each type of investments significantly explained the variance of all three criteria (see Tables 5 and 6). The greatest proportion of variance, for both men and women, was explained for the satisfaction with the relationship, somewhat smaller for the relationship quality, and the smallest for the relationship stability. Discussion One of the reasons for including three different measures of the partners' perception of their relationships was to investigate the relations among different dependent variables used in the research of close relationships. The correlation among relationship quality and satisfaction with the relationship confirmed our hypothesis about these variables being highly correlated constructs, probably referring to the same aspect of a relationship. Relationship stability, on the other hand, has been proved to be a somewhat different construct. This is in line with our expectations and with the Rusbult’s investment model, because even relationships that are not very satisfying can be stable if partners have already invested a lot in the relationship and find the alternatives not appealing. Satisfaction with the distribution of investments As shown in Figure 1, both sexes are the most satisfied with distribution of financial investments when financing is equally divided between partners. There are no sex differences in satisfaction when distribution is either equal, or when one perceives that the other partner contributes more. When the distribution is unequal, women who contribute more are less satisfied than men who contribute more – that is, women who perceive that they pay most of the bills are the least satisfied. Considering the traditional gender roles, such an arrangement would be the least expected and surely has an impact on the comparison level for women in our sample, which are fairly well educated, have their own salary, and therefore are financially independent. Interestingly, although women are the least satisfied when they finance their family by themselves, they are also less satisfied when their partners pay all the bills (compared to equal investments). This supports the basic assumptions of the equity theory and shows that the traditional way (men financing the family, women being housewives) is not completely satisfactory for modern couples in Croatian society, but neither is the reversal of the traditional gender roles. Since almost 80% of our participants were employed, it seems that for women and men in couples with both partners employed it was not satisfying that only one of them mostly financed the family. Figure 2 shows that participants with an academic education were somewhat more satisfied than participants with a lower education level. It could be assumed that more educated participants earned more money and contributed more to the household budget and therefore felt more satisfied with financial issues. This difference becomes especially apparent in the group of participants who perceive that they contribute more: the participants with a high-school education are less satisfied with such a distribution compared to participants with an academic education. If the education level is reflected in one’s salary, it is not surprising that the least satisfied with the distribution of financial investments would be those who earn less and still have to provide for their family. Similarly to the results obtained for financial investments, the participants were the most satisfied with the decision making in their relationship if both partners contributed equally. The level of education in our sample (high-school or higher) indicates that our participants probably perceive themselves as competent individuals, not wanting to be excluded from making important decisions in their relationships. On the other hand, people do not like to be solely responsible for making all the decisions, and therefore an equal participation in decision making is the most satisfying solution. It seems that men's perception of how much they work around the house and take care of the children has no impact on their satisfaction with the distribution of housework (Figure 3). This might seem puzzling if we do not consider the distribution of investment in housework for both sexes, which is rather unequal. Namely, 87% of women perceive that they do more housework than their partners, and, as can be seen in Figure 3, they are less satisfied with such a division. Hence, the majority of men are burdened with less housework than their partners, and they are satisfied with this traditional gender role. It can be assumed that the minority of men which equally share housework with their partners, or even work more, are those men who have egalitarian gender attitudes and therefore are satisfied with such a division of responsibilities between themselves and their partners. Relationship quality, stability, and satisfaction with it As the results of the regression analyses with satisfaction with the relationship and relationship quality as dependent variables are very similar (as would be expected considering that those two variables proved to measure very similar concepts), we shall discuss them together. The regression analyses show that the variances of both partners’ satisfaction with the relationship and their perception of the relationship quality can be explained by each partner’s satisfaction with the distribution of financial investments, decision making, and housework and childcare. The only significant predictor from the first block of variables was the female's assessment of housework investments (the more she invested, the less she was satisfied, and perceived the relationship of lower quality). None of the other predictors entered in the first step contributed significantly to the variance of the dependent variable(s). All three variables entered in the second block proved to be significant predictors of both partners’ satisfaction with the relationship: the satisfaction with financial investments, housework, and decision making distributions. The list of significant predictors was the same for the relationship quality as the dependent variable, with the exception of men's satisfaction with the distribution of financial investments. As can be seen in Tables 5 and 6, the beta ponders are positive, meaning that greater satisfaction with the distributions of those investments led to a greater overall satisfaction. To summarize, we can conclude that the distribution of investments did not contribute significantly to the partners' overall satisfaction or to the quality of their relationship, while their satisfaction with such distributions of investments did. The satisfaction with a given distribution is associated with the “comparison level” in the Rusbult’s model – partners’ expectations about the costs/rewards rate in a relationship directly affect their satisfaction with this rate, resulting in their perception of relationship quality and their satisfaction with the relationship. The list of significant predictors is somewhat different for the relationship instability as a dependent variable. None of the variables in the first block (distribution of investments) had significant beta ponders. It seems that when it comes to housework, women partly accept the traditional gender role: although working more around the house makes them dissatisfied, not only with such a distribution of investments but also with their relationship in general, it does not affect the relationship stability. This could also be explained by the lack of alternatives. The division of the housework is still traditionally gendered in most of the families in Croatian society, so these women, although unsatisfied, do not think about breaking the relationship because they do not expect to be better off in some other relationship. When the second block of predictors (satisfaction with the distribution of investments) was entered, both partners’ satisfaction with their participation in decision making was significant, as was the men's satisfaction with the distribution of housework, and women’s satisfaction with the distribution of finances: the more they were satisfied with the distribution of those responsibilities, the less they perceived their relationship as instable. However, it should be noted that the percentage of explained variance of the relationship instability is actually low (R2men= .157; R2women= .132). Overall, we can see that the satisfaction with the relationship and its quality can be best predicted with both partners’ satisfaction with their role in decision making, followed by women’s satisfaction with the division of housework, and, finally, by both partners’ satisfaction with the distribution of finances. On the other hand, if partners are unsatisfied with the division of the decision making, men with the division of housework and women with the division of financial investments, it would affect the relationship instability – they would more likely consider the break-up. In view of the theoretical approaches we have discussed earlier, the results have shown that financial investments, housework and decision making, operationalized and measured as it was done in this research, are seen by participants more as the costs/rewards than as their investment in a given relationship. They contribute to the relationship quality and satisfaction with it more than they explain the relationship stability. Therefore, they may become the reason for dissatisfaction with the relationship and even considerations about ending it, but they are not the factors that would keep partners in a relationship that they are not satisfied with. These results support both the social exchange theory and the equity theory. The satisfaction with the distribution of partners’ investments proved to be more important than the actual distribution of investments between partners - a satisfactory exchange of this kind of investments in a relationship predicts the partners’ satisfaction. This is in line with the research of Mikula (1998, 2004; Mikula & Freudenthaler, 2002), which emphasizes the importance of perceived fairness and social justice in a romantic relationship.
