Parent-child sex communication is a complex and multidimensional construct, and effective measurement tools that reflect this complexity are scarce. The purpose of this study was to develop and test an assessment tool of parent-child sex communication that reflects the multidimensional nature of the construct and which can be flexibly administered between both parent and adolescent informants. Using two large national samples from the United States involving adolescents (N = 2,044; = 16.19, = 1.71) and unrelated parents of adolescents (N = 2,081), we psychometrically tested the Parent-Child Sex Communication Inventory (PCSCI). Validity evidence (i.e., construct, discriminant, convergent, and divergent) supported a 30-item measure that consisted of three overarching dimensions distributed along seven subscales: of sex communication (about , about , and about the ); the of sex communication ( communication versus communication); and sex communication (involving and ). The PCSCI is an assessment tool for tapping multiple fundamental dimensions of parent-child sex communication that is quick and easy to administer. Further, it can be administered to both parent and adolescent informants. Therefore, it represents a significant methodological advancement for continuing research on parent-child sex communication.
