Here's a place to start. Some of these articles have measures attached. Also, it depends what kind of empathy you're talking about. I hope this helps!

What is your research question?

well my basic research question is is to see if there are specific types of pet owners who are high on empathy and has a specific attachment style.

I am using Animal Empathy scale. its a good scale but i am confused about the scoring and analysis.

It would be great if you share if you know anything about this.

Thank You
