Investigating certain research questions may involve linking the responses of one adolescent to those of another adolescent interviewed in the Add Health Survey. The goal of the analysis will be to characterize the behavior of a pair of adolescents rather than the behavior of an individual adolescent . Unfortunately, the available sampling weights are appropriate only when the analysis seeks to investigate behaviors of individual adolescents. However, an appropriate sampling weight can be constructed for each pair of adolescents and used to correct for clustering and unequal probability of selection of the pair. This paper covers the types of pairs of adolescents that can have a pair weight constructed, describes the necessary formulas and data, and concludes with an example showing how to compute pair weights for romantic partners from the Wave II In-home Interview.
