COURANT -- May 7 -- eHarmony claims its scientific system is responsible for 118 marriages a day. The site has expanded into couples counseling in the past two years with eHarmony Marriage, an online therapy service for people who are married or in committed relationships. There's no traditional talk therapy involved. Instead, couples answer an extensive questionnaire and receive a computerized assessment of their relationship's strengths and weaknesses. Based on that information, eHarmony prescribes a series of self-directed exercises and interactive videos that target their trouble areas — communication, intimacy and conflict resolution, for example.
