How would investment model researchers like rusbult and martz (1995) explain why battered women often return to their abusive partners?

These women might be poor and have no other economic alternative.

The Investment Model is a nonpathologizing theory that views commitment as a function of one's satisfaction with, alternatives to, and investments in the relationship. These factors were examined in a shelter-based sample of battered women. Investment model variables, particularly satisfaction, were also examined as mediators of the relationship between abuse exposure and commitment. Both Investment Model and abuse exposure constructs were assessed using instruments more fully developed than in previous research. Results indicated that each of the Investment Model factors contributed uniquely to women's commitment, and that relationship satisfaction mediated the relationship between psychological (but not physical) abuse and commitment. Implications for future research and intervention are discussed.
