This study examined the impact of technology on couples in committed relationships through the lens of the couple and technology framework. Specifically, we used data from 6,756 European couples to examine associations between online boundary crossing, online intrusion, relationship satisfaction, and partner responsiveness. The results suggest that participants' reports of online boundary crossing were linked with lower relationship satisfaction and partner responsiveness. Also, lower relationship satisfaction and partner responsiveness were associated with increased online boundary crossing. The results suggest that men, but not women, who reported greater acceptability for online boundary crossing were more likely to have partners who reported lower relationship satisfaction in their relationships. Implications for clinicians, relationship educators, and researchers are discussed.

Individuals are now using mobile devices on a daily basis to share and communicate in many ways, such as through text messaging, sharing photos through Instagram, sharing experiences through Twitter, posting on Facebook, and video chatting. Communicating through technology, or computer-mediated communication (CMC), has created a new form of connectedness for families and couples that is based on remote digital interactions and shared experiences (Kennedy, Smith, Wells, & Wellman, 2008).
