The role of individuals’ and their partners’ positivity in the satisfaction with the relationship: An Actor-Partner Interdependence Mediation Model
Over the last thirty years, the actor-partner interdependence model (Kenny, 1996) became an important methodology to address interpersonal perceptions in dyads. In this contribution, we present each practical step to conduct an extended version of it, the actor-partner interdependence mediation model (Ledermann, Macho, & Kenny, 2011) using multilevel modeling. Specifically, we posit that individuals’ and their romantic partners’ positivity, a personality disposition, enhance relationship satisfaction, through the individuals’ perceptions of partners’ positivity.
