I don't think there is any solid scientific evidence to back up the claim. However, a recent research conducted in the UK revealed that women are generally more worried about their debts than men are.

On a personal level, I can agree with this research because among all my couple friends, I have noticed that the women are usually the ones to handle all of their finances. Also, I tend to think that women are more thrifty when it comes to shopping and finding deals.
On a different note, I think it is commonplace to find that couples with the same tradelines and debts have varying credit scores.
How is this possible? Well, for one thing, credit scores are derived using complex algorithms. These algorithms may take into account your spending behaviors as well as your past credit history. Also, I think it is safe to assume that no two people have the same exact credit history; such as tradelines, credit limits, and activity dates. You have to remember that your individual credit score has existed long before your marriage.
I like to think of the credit report as your personal finance life story; pages are turned and new chapters are added.
