Several theoretical models have described the ways that patients and partners respond to a health problem. Most of these models are faced with limitations regarding the role of cognitive/emotional appraisals and coping behaviors, and the potential interactions between individual and dyadic variables. Therefore, new theoretical approaches are needed to capture the multiple processes that take place within dyadic adaptation to illness. Here, the major aspects of the dyadic adaptation/dyadic coping models are reviewed and their limitations are outlined. Moreover, a new theoretical approach to the dyadic-regulation processes that are important for adaptation to illness is proposed. The Dyadic-Regulation Connectivity Model emphasizes the concept of system connectivity and the role of central network hubs in dyadic regulation. Network hubs represent the common 'space' between intra- and inter-personal processes, and are closely connected to each other. The model posits that dyadic regulation processes evolve over time, all network hubs are fully responsive to changes in any part of the mechanism, while the entire mechanism is nested within the self- and the dyadic-system, the illness, and the broader socio-cultural contexts. The theoretical and research implications of the proposed model are also discussed.
