The purpose of this study was to adapt "The Boundary Violations Scale" (Madden et al., 2002), which was created to measure the intergenerational boundary violations in families from the perspective of children, to Turkish and to test the validity and reliability of the Turkish version of this instrument. This instrument was developed based on structural family therapy and aimed at measuring boundary violations in three areas: Promoting Maturity, Forming Coalitions, and Communicating as Peers. The research participants consisted of 511 students and 114 parents who lived in an eastern Mediterranean city in Turkey. To determine the validity of the scale, the students' mothers were asked to complete the O'Leary-Porterand Dyadic Adjustment Scales. An explanatory factor analysis is conducted to examine the construct validity of the scale. The results of the analysis established the consistency between the adapted and original scales. The results of the study suggest that the Turkish version of the "The Boundary Violations Scale" is conceptually equivalent to the original and satisfactorily reliable and valid.
