On the use of social relations and actor-partner interdependence models in developmental research

We offer comments on the eight works contained in the Special Issue, all of which use advanced methods for analysing interdependencies using variants of the Social Relations Model (SRM) or the Actor-Partner Interdependence Model (APIM). After critically discussing the SRM and APIM as used in these works, we describe similarities and differences between these two approaches. We also discuss the substantive contributions of this collection and then offer our suggestions for future development of the two models.
