Evaluation of Equity Theory
Psychology: AQA A Level, topic 9.2.4
Support for Equity Theory
There is significant support for equity theory from research studies, including studies of real life relationships. Research confirms that equity theory is a more valid explanation than social exchange theory (SET).

Utne et al. (1984)
- Utne et al. (1984) conducted a survey of 118 recently married couples (husbands and wives aged between 16 and 45 who had been together for more than two years before marrying).
- They measured equity with two self-report scales.

Utne et al. (1984) findings
- Utne et al. (1984) discovered that couples who considered their relationship equitable were more satisfied than those who saw themselves as over benefiting or under benefiting
- This confirms the main prediction of equity theory.
Criticisms of Equity Theory: Cultural and Individual Differences
Some researchers argue that equity theory does not account for individual differences and cannot be applied cross-culturally.

Challenges
- Equity theory assumes that equity is fundamental to all romantic relationships. But studies have found that this assumption is not universally applicable.
- Aumer-Ryan et al (2007), found views regarding equity and satisfaction are not identical between cultures.

Cultural differences
- This challenges equity theory because the theory claims that equity is a universal need in relationships.
- This means that the theory is limited because it cannot account for this cultural difference.

Aumer-Ryan et al. (2007)
- Aumer-Ryan et al. (2007) compared couples in a collectivist culture with those in an individualistic culture.
- Couples from the individualistic culture considered their relationships to be most satisfying when the relationship was equitable.
- Partners in the collectivist culture were most satisfied when they were over benefiting.
- This was true of both men and women.

Huseman et al. (1987)
- Not all partners in romantic relationships are concerned about achieving equity.
- Huseman et al. (1987) suggested that some people are less sensitive to equity than others.

Findings
- They described some partners as benevolents (those who are prepared to contribute more to the relationship than they get out of it).
- Others they described as entitleds (those who believe they deserve to be over benefited and accept it without feeling distressed or guilty).
- This shows that equity is not necessarily a universal feature of all romantic relationships.
Criticisms of Equity Theory: Types of Relationships
Equity theory also seems to overlook the fact that many different types of relationship exist.

Clark and Mills (2011)
- Clark and Mills (2011) tried to untangle the sometimes confusing body of evidence that claims equity is an important feature of relationships.
- They concluded that there are many types of relationship that we should distinguish between, such as business and work relationships and acquaintance relationships.

Other studies
- Equity theory also claims that satisfying romantic relationships should become more equitable overtime.
- Berg and McQuinn (1986) found that equity did not increase in their longitudinal study of dating couples.

Longevity
- Equity theory also did not distinguish between those relationships which ended and those which continued.
- Other variables were found to be significantly more important, such as self-disclosure.
