For years observational techniques along with other methods have sought to explore the relationships of couple interactional exchanges to marital quality and longevity. However, many of the previous methodological procedures used might be inadequate at capturing the influential micro-dimensional nuances of interpartner couple affective stability and reciprocity. This study explored the dyadic patterns in 23 married couples' continuous affect ratings during two communication episodes. Multilevel modeling was used to assess the structure in the stability of one's own affect and the influence of partner affect over 3-, 6-, and 9-second time lags. Implications regarding the use of nested models to explore patterns of actor and partner effects are discussed.
