Q

Why is there an issue with measuring the variables in the investment model (eval)

A

It is difficult to measure commitment and other factors that lead to it, such as quality of alternatives. Rusbult developed the “Investment Model Scale” to overcome this problem, finding the scale to be high in both reliability and validity in the measurement of these variables. However even this scale relies on self-report measures, which often have problems with respondents wanting to present themselves in a good light, raising possible bias

Q

How can this model explain real world abusive relationships (eval)

A

Victims of partner abuse experience low satisfaction, which could lead us to predict they would leave an abusive partner, yet despite this many stay. The investment model highlights possible reasons for this, for example, lack of alternatives to the relationship or may have too much invested with that partner, making dissolution too costly. Real life studies of battered women at shelters revealed that lack of alternatives and investments were a strong indication of whether or not they would return to their partner

Q

Why does the investment model fail to account for the future (eval)

A

Goodfriend and Agnew suggest that investment should not only include things that have already been invested, but also plans that partners have made regarding the relationship. In ending the relationship, the individual would lose the possibility of achieving these plans. Therefore some relationships persist, not because of current balance of investments but because of a motivation to see cherished future plans occur

Q

Why is there wide application of the investment model (eval)

A

It’s claims have been shown to be true across many different populations and different types of relationship (obviously because they are basic af), for example research has supported it’s relavance in diffirent cultures, such as the US, Netherlands and Taiwan, as well as across different populations, such as marital and non-marital, LGBT relationships, friendships and abusive relationships.
