However, much of the research into virtual relationships is conducted using self-report methods (questionnaires and interviews) which are prone to social desirability bias, where participants may have lied about how much they self-disclose in a virtual relationship to present themselves in a better light, so they don’t appear like they have disclosed too much to people they have never met. This limits the internal validity of the research and the extent it can be used to contradict the hyper-personal model of self-disclosure in virtual relationships.
