Kommissarie Curiosa is on the case
In Sweden, there is no dating culture as such. Swedish dating is usually very informal and there are no particular "rules" or traditions regarding dating procedures. Surely, romantic relationships are important to Swedish adolescents when forming an identity; however, to find a way to measure identity status within that area would first require for example, an investigation of how Swedish adolescents form romantic relationships, and what the process of getting to know someone to whom you are attracted looks like.
See, even academics who study the "Swedish identity" aren't even sure how one goes about dating in Sweden. They do, however, identify a need to "investigate how Swedes...form romantic relationships."
Maybe I should refer them to Swedish Mating and Dating. I've already started the field work, and even a little bit of theorizing. I think I have the topic for my doctoral dissertation.
