AbstractThe analysis of longitudinal data collected from nonexchangeable dyads presents a challenge for applied researchers for various reasons. This article introduces the dyadic curve-of-factors model (D?COFM), which extends the curve-of-factors model (COFM) proposed by McArdle (1988) for use with nonexchangeable dyadic data. The D?COFM overcomes problems with modeling composite scores across time and instead permits examination of the growth in latent constructs over time. The D?COFM also appropriately models the interdependency among nonexchangeable dyads. Different parameterizations of the D?COFM are illustrated and discussed using a real data set to aid applied researchers when analyzing dyadic longitudinal data.
