Which studied applied rustbalt’s investment model to explain why people stay in abusive relationships?
Rusbult and Martz (1995)
What was the procedure of rusbult and martz (1995)?
. Asked women who were living in refugee why they stayed with abusive partner instead of leaving as soon as the abuse began
What were the findings of Rusbult and Martz?
Women stayed committed to the relationships as their economic alternative so were poor and their investment was great (deterred them from leaving the relationship even though satisfaction was low)
. Also shows that satisfaction isn’t as important as commitment in staying in relationships
How does Lee and Agnew (2003) support Rusbult’s investment theory?
. Meta analysis of 52 studies from 1970-99
. 11,000 participants from 5 countries
- such a big sample size increases the validity
. Found that satisfaction, comparison with alternatives and investment all predicted relationship commitment
. High levels of commitment = most successful relationships
. Outcomes were true for homosexual couples too
