Per the New York Times, a number of efforts are afoot to provide on-line tools for "preventive maintenance and assessment" for married couples. (Providing relationships with something between scheduled maintenance/inspection visits by your car dealer, and your annual physical?)
Professors from UCLA and University of Miami are soliciting 500 married couples to participate in a study of on-line self-help couples therapy.
Researchers at Brigham Young offer an (inexpensive) on-line martial/relationship assessment which, they say, yields a graphic report depicting a couple’s communication and conflict style, and how much effort each partner puts into the relationship.
A similar assessment tool is also being studied in Australia as part of a telephonic and remote program of marital counseling, intended for those in remote areas who simply cannot practically arrange for face-to-face contact with a counselor.
