I need to know the conceptual framework from which you address the problem before placing predictors. I think from psychoanalysis English School (Peter Fonagy) on the subject of attachment. I think it's the first pattern that each of us backtrack to the separation and then adult repeated. There are interviews and scales to "measure" or "assess" the type of attachment. In my view, this could be from psychoanalysis, an excellent predictor of subsequent coping mode other emotional losses. Greetings To You !! I suggest This link  about it :

Poor coping skills are well preidicted by attachment styles. You might look at Mikulincer and Shaver's 2007 book, or the work of Gurit Birnbaum. The work of Ickes on empathic accuracy in relationships and that of Jeff Simpson may also help you.
