Abstract
Although previous findings suggest a link between adults’ use of social networking sites (SNS) and relationship commitment, research has been lacking. This study of 427 emerging and young adults (aged 18–32 years, 71.20% female) indicated that exposure to alternative partners on SNS was indirectly related to relationship commitment through the pursuing of alternative partners on SNS. The more frequently they were exposed to alternative partners on SNS, the more they engaged in pursuing these alternative partners, which negatively affected their relationship commitment. Furthermore, a positive relation between exposure and romantic comparison to alternative partners was found. Gender did not moderate these relations. The discussion focuses on the implications of the findings for relationship development.
