Dyadic Interdependence in HF care Typology

Dyadic Type	Defining feature	Subtypes	Characteristics	Context
Patient oriented dyads	The patient takes care of the majority of their self-care without input from the caregiver	The patient may either choose to take control their HF care without the involvement of the caregiver OR The caregiver may choose to be uninvolved in the HF care	Individually oriented	Most common early in the HF trajectory (Stage A & B)
Caregiver oriented dyads	The caregiver, not the patient, takes care of the majority of the patient’s self-care without input from the patient	The patient may defer all care decisions and actions to the caregiver OR The caregiver may take responsibility for the care from the patient	Individually oriented	Most common in the last stage (D) of HF where patients are no longer able to care for their own HF
Collaboratively oriented dyads	Patients and caregivers actively and together make decisions and take action when needed to maintain and manage the patient’s HF	This collaboration reflects either a healthy OR Unhealthy (enmeshed) collaboration determined by dyadic report and successful HF outcomes	Relationally oriented	Found across the trajectory of HF but less frequently in the advanced stages of HF
Complementarily oriented dyads	The patient and caregiver have negotiated spheres of non-overlapping responsibilities for HF care	One takes the lead on a particular activity (for example HF care) whilethe other takes the lead on another activity (ADLs or IADLs) OR The patient and caregiver may have differential functional or cognitive limitations resulting in one taking the lead on decision making while the other provides the actual behavior when cued	Relationally oriented	Found across the trajectory of HF but less frequently in the advanced stages of HF
