Are they any journal articles on a measure of independence and interdependence (Singilis)?
Check your local library for psychology journals... your librarian can help you with that.
I Googled Singilis and found nothing useful.
I suggest you follow GuruBlue's suggestion about checking your local library.
I'm not sure what you mean by "Singilis."
It might be helpful to limit your measures of independence and interdependence to a specific situation or type of relationship.
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. If not, repost your question in more specific terms. Thanks for asking.
