DescriptionOnline dating is a popular method of meeting potential mates. The Internet Dating Use and Outcomes (IDUO) model attempts to delineate the personality and situational factors that lead up to the choice to try online dating, as well as to explain the factors that combine to form a self-perceived successful experience. Study 1 surveyed a sample of Internet users to test the IDUO model's hypothesized relationships between "trigger events", self-perceived time available for traditional dating methods, and attachment style and the choice to try online dating. Study 2 surveyed the users of an online dating website to test whether the ability to find similar others and increased amounts of communication predicted two aspects of success, and the means through which amount of communication related to success. In both studies, attachment styles within the sample of online daters demonstrated a different profile than expected in the general population, with a decreased number of securely attached individuals and an increased number of preoccupied and fearfully attached individuals.
