Equality Matching EM relationships are based on a principle of equal balance and one-to-one reciprocity. Salient EM manifestations are turn-taking, democratic voting one person, one votein-kind reciprocity, coin flipping, distribution of equal shares, and tit-for-tat retaliation. The Market Pricing MP model is based on a principle of proportionality. Relationships are organized with reference to socially meaningful ratios and rates, such as prices, cost-benefit analyses or time optimization.
Rewards and punishment are proportional to merit. Abstract symbols, typically money, are used to represent relative values.
A Generic Model of Dyadic Social Relationships
MP relationships are not necessarily individualistic; for instance, utilitarian judgments seeking the greatest good for the greatest number are manifestations of MP. The four relational models have in common that they suppose a coordination between individuals with reference to a shared model.
To these, Fiske adds two limiting cases that do not involve any other-regarding abilities or coordination [ 1 ] pp. In order to better understand RMT, it is helpful to locate it in the landscape of other social, political and economical theories. Here we follow closely the review made by Senior et al.
RMT is identified as a theory of constrained relativism, which lies between the two extremes of rational choice analysis and poststructuralism. Theories belonging to the two latter domains have dominated political science, sociology and economy for several decades, while constrained relativism has had less influence and is not as widely known. Rational choice theory holds that people are fully rational, follow their self-interest and instantly process all available information.
Universal analytical models are thus expected to predict the behavior of these rational agents. At the other extreme, poststructuralism posits that every person, society and epoch, is fundamentally unique. According to that view, no generalization can be made; only descriptions are possible and relevant, without offering any prospect of scientific prediction. Of the two dominant positions, rational choice theory has been favored in many scientific domains, since it calls for the construction of explanatory and predictive models, forbidden by the very definition of poststructuralism.
Yet alternatives to rational choice theory are on the rise, as it is apparent that people are strongly and primarily influenced by emotions, feelings and subconscious processes. Notably, rational choice theory fails at explaining or predicting major social, economical or political events, such as financial bubbles and crashes, or social and political revolutions.
Occupying the middle ground between the two extremes of rational choice theory and poststructuralism, theories of constrained relativism are based on the idea that there is a limited number of elementary ways of organizing social relations that serve as building blocks for the infinitely varied aspects of social and political life. MPlus was specifically designed to work with categorical data. With the MIMIC models we regressed the DRS factors on the background variables age, gender, kin relationship, length of relationship, and caregiver or care receiver role.
We evaluated the association between DRS scales and patient and caregiver depressive symptoms with structural equation modeling. Finally, we estimated the reliability and discriminant validities of the dyadic relationship scales.
We estimated scale reliability using the ratio of the sum of the item loadings squared times the variance of the scale over the sum of the item loadings squared times the variance of the scale plus the sum of the item variances. We estimated the reliability using the following equation: These authors proposed using the average variance extracted AVE statistic as a measure of convergent validity.
In different terms, AVE is a measure of the error-free variance of a set of items. If the squared correlation between two LVs is less than either of their individual AVEs, this suggests the LVs each have more internal extracted variance than variance shared between the LVs. Missing Data Most missing data were due to skipped pages or randomly omitted answers, and we assumed these to be missing at random.
We used multiple imputation methods to impute missing data by imposing a probability model on the complete data and observed and missing values Schafer, We used only matched pairs of patients and caregivers for this analysis. However, there was a significant difference in the agreement-to-participate rate based on the home health care office serving the patient.
We compared the patients who participated without a partner to the patients with a partner on the variables age, gender, length of relationship, KPS, CES-D, strain, and positive interactions. These comparisons of patients with and without a partner participating were not significant, except for the strain variable. We also used the same variables to compare the group of family caregivers who participated without a patient and caregivers who participated with a patient.
Leader–member exchange theory
The only significant difference for the caregiver groups was on the KPS variable. There was no significant relationship between age and the DRS dimension see Table 2. Because of the lack of a significant relationship between age the DRS scales, and due to the observation that family care occurs across the life span, we believed it was important to include chronically ill younger patients in our results.
The median KPS score was 4 range 1—10 based on patient self-report and 5 range 1—10 based on caregiver self-report, indicating that more than half of the patient participants required occasional assistance. The intraclass correlation between the patient and caregiver KPS ratings was 0. When patients do not meet Medicare criteria for homebound or are medically stable, they are discharged from home care services to the care of their families.
Thus, many of the participants were discharged from home care services when they completed the surveys. Their no longer meeting Medicare criteria for homebound status may have been reflected in the lower KPS scores. Caregivers were related in a corresponding manner to the patients: Members of the dyads had known each other on average for 41 years.
Interclass correlations and CIs are reported in Table 2. Most of the interclass correlations were low to moderate range 0. DRS Item 6 i. For the EFA, we combined the patient and caregiver data to model the dependency between the two members of the dyad and analyzed one- two- and three-factor solutions using the following criteria: A two-factor solution represented the patient and caregiver data adequately in that all items loaded on the same factors with factor loadings from 0.
The six positive items loaded on the first factor for both patients and caregivers positive dyadic interaction. The positive items indicated a person felt closer, had improved communication, had more patience, and learned good things about oneself as a result of family care. The negative patient and caregiver items loaded on the second factor dyadic strain. The dyadic strain items indicated feelings of anger, strain, and resentment resulting from family care.
In the CFA we defined the correlated variables within dyads and specified the model for a the patient positive dyadic interaction and dyadic strain and b the caregiver positive dyadic interaction and dyadic strain.
MPlus modeled the dependency across the dyad and incorporated this into the modeling.

The patient factor loadings ranged from 0. One item on the caregiver strain subscale is not included on the patient strain scale i. The caregiver factor loadings ranged from 0. The variance explained for each factor was as follows: The fit indices supported the fit between the data and the model.

These correlations suggested that the person's own positive and negative dimensions were correlated, and the within-dyad positive and negative dimensions were related to the respective positive and negative dimensions of the other person.
We used MIMIC models to evaluate the separate associations between the background variables age, gender, kin relationship, length of relationship, and caregiver and care recipient role and the DRS scales.
None of these background variables had a significant relationship with the DRS dimensions. These findings supported the DRS's measurement invariance across age, gender, kin relationship, length of relationship, and the role of caregiver and recipient. Their analysis found a positive correlation between the member's perceptions of LMX and the leader's ratings of the member's job performance. It also found an even stronger positive correlation between the leader's perceptions of LMX and the leader's ratings of the member's job performance.
They further explain that LMX perceptions may cause a leader to form positive or negative expectations about an employee which can then affect actual employee performance rather than only performance ratings. This meta-analysis also found statistically significant positive correlations between LMX and objective performance as opposed to subjective performance ratingssatisfaction with supervisor, overall satisfaction, organizational commitment, and role clarity.
It found statistically significant negative correlations between LMX and role conflict and turnover intentions. The analysis found that the relationships between LMX and citizenship behaviors, between LMX and justice outcomes, between LMX and job satisfaction, between LMX and turnover intentions, and between LMX and leader trust are stronger in horizontal-individualistic cultures than in vertical-collectivist cultures.
The analysis also found that there is not a cultural difference in the relationships between LMX and task performance and between LMX and affective and normative organizational commitment.
That is, citizenship behaviors targeted at individuals are more strongly correlated with LMX than are citizenship behaviors targeted at an organization. Vertical dyad linkage theory has become widely known as leader—member exchange theory, although researchers such as George B. According to LMX, the quality of this dyadic relationship predicts attitudinal and behavioral outcomes such as those discussed above at the individual, group, and organizational level.
