I find studies produced by the Gottman institute far more compelling because they're much more prescriptive. In particular they analyze the "four horsemen" of conflict in a marriage and how these undermine marriage stability: http://www.gottmanblog.com/2013/04/the-four-horsemen-recogni...

The long term presence of these "four horsemen" is a strong predictor of divorce, and the recognition of their presence is a good sign that a marriage needs help.
