Communication is generally accpeted as one of the most crucial facets of interpersonal relationships. Olson, Russell, and Sprenckle has developed a theoretical model of marital and family systems known as the Circumplex model. They hypothesized that effective communication facilitates movement to and maintenance of systems at the desired(balanced) level on the two collected from 116 families(a couple and an adolescent) through the questionnaire method based on FACESⅢ, Parent-Adolescent communication scale, and Sociodemographic sheet. In this study, the correlation between Parent-Adolescent communication and sociodemographic factors was evaluated. The higher Father-Adolescent communication level was related to the higher educational and economic status. The Mother-Adolescent communication level was not related to any sociodemographic factor. It was evident that the families with high reported cohesiveness and balanced families had the most positive communication patterns.
