Jason S. Carroll is the Family Research Director at the Wheatley Institute at Brigham Young University and a senior fellow at the Institute for Family Studies. He has published widely on links between marriage and human flourishing, marriage readiness among young adults, and modern threats to marriage.  Dr. Carroll was awarded the Berscheid-Hatfield Award for Distinguished Mid-Career Achievement, an annual award given for distinguished scientific achievement by the International Association for Relationship Research (IARR). Dr. Carroll is best known professionally for his development of the “Developmental Model of Marital Competence,” the widely used “Marital Horizon Theory” of young adult readiness for marriage, and “Sexual Restraint Theory,” which has been used to demonstrate the benefits to couples who wait until they are married to begin their sexual relationship. Most recently, Dr. Carroll has received recognition for his co-development of the “STRIVE-4 Model of Virtue” that provides a comprehensive model to organize and guide a mature science of the role personal virtues play in human flourishing.
