How should I measure attachment in preschool children (3-4 years old)?

I wish you good luck!

That is new to me, thanks so much.

I think Rene Gilles' adapted methodology for examining children's attachment may be appropriate for your research. She has developed criteria for evaluating emotional attachment. But for children that are 5 years old or more, you should use the model of N. Kaplan, which also measures the types of emotional attachment in children.
