Cell phones have become important communication media for individuals in romantic relationships. The frequency of and methods used for communication may vary by adults' style of romantic attachment. Female university students (N = 31) currently in romantic relationships responded to a questionnaire. They estimated the frequency of calls and text messages received from and made to their romantic partners and completed the Experiences in Close Relationships-Revised instrument, a measure of attachment anxiety and avoidance. Also, the participants reviewed their cell phones' memories and provided accurate frequency of communication to and from the romantic partner. Attachment anxiety was associated with more estimated text messages sent to and received from the romantic partners and actual text messages sent to and received from the romantic partners. Attachment avoidance was associated (r = −.38) with fewer estimated calls made to the romantic partners and fewer actual calls made to the romantic partners (r = −.34).
