Recent publications describing long-term results of longitudinal investigations of divorced couples have stirred controversies because of substantial differences in findings. The current Special Collection was initiated to clarify some of the issues brought into controversy.

Why do various research findings on the long-term effect of divorce tend to disagree so substantially? Why is divorce considered a problem? What do children have to say about their experiences with divorce? And what, if anything, can be done to help the children of divorce?
