Jin conducted a study to compare the proportions of attachment types in Korea to other studies. The SS was used to assess 87 babies. The overall proportions of insecure and secure babies were similar to those in most countries; most babies being secure. However, more of those classified as insecurely attached were resistant, only one baby was avoidant. This distribution is similar to the distribution of attachment types found in Japan (IJzendoorn & Kroonenberg). Since Japan & Korea have quite similar child-rearing styles this similarity might be explained in terms of child-rearing style.
