Dyadic Disruption Theory

New Opportunities for Advancing Dyadic Health Science in Gerontology

As dyadic health science enters a golden age, important conceptual, theoretical, and technical challenges remain. This forum review brings together perspectives on the burgeoning dyadic literature from several subdisciplines within aging research. We first define key concepts and terms so that interested researchers can navigate the complex and various ways in which dyadic health research is conducted. We discuss exciting scientific advances and close by identifying crucial challenges and considerations that coincide with important future directions for the field.

Family-authored ICU diaries to reduce fear in patients experiencing a cardiac arrest (FAID fear): A pilot randomized controlled trial

Survivors of cardiac arrest (CA) and their family members often experience significant fear-based distress (cardiac fear; i.e., fear about the CA survivor's heart). Fear-based distress after CA is associated with higher rates of cardiac event recurrence and mortality in CA survivors. As posited in Dyadic Disruption Theory (DDT), cardiac fear in family members may contribute to the development of distress in CA survivors via socially-based mechanisms. Thus, interventions to reduce family distress may improve CA survivors' outcomes. ICU diaries are easy to implement and scalable and show promise for reducing distress after CA but are primarily targeted towards survivors. The primary aim of the Family-Authored ICU Diaries to reduce Fear in Patients Experiencing a CA (FAID Fear) pilot randomized controlled trial was to test feasibility of an ICU diary intervention targeted towards family member distress alone. Family members of patients hospitalized after CA (N = 16) were randomized 2:1 to receive the FAID Fear intervention or usual care. Intervention participants were provided brief instructions and were asked to write in the diary twice per week until the end of hospital care. Assessments occurred at baseline enrollment, end of hospital care, and 30 days later. Participants' mean age was 50.73 years (SD = 13.41; 80% cis-gender female; 60% White). Recruitment (16/25 referred; 64.0%), retention (14/16 enrolled; 87.5%), and intervention adherence (7/10 completed; 70%) were promising. Most agreed that the ICU diary intervention was appropriate (7/10 completed; 70.0%), feasible (9/10 completed; 90.0%]), and acceptable (8/10 completed; 80.0%). Fear was nonsignificantly lower in intervention participants (v. control) at end of hospital care and 30 days later. FAID Fear represents a first step in building theory-based dyadic interventions that can be implemented to support family members of CA survivors in the ICU, with potential to improve outcomes in CA survivors.

Together from the start: A transdiagnostic framework for early dyadic interventions for neurodegenerative diseases

BACKGROUND

Neurodegenerative diseases (NDDs) are increasingly prevalent and radically alter the lives of individuals and their informal care partners (together called a dyad). As symptoms progress, dyads are at risk for elevated emotional distress and declines in relationship functioning and quality of life. Psychosocial interventions delivered to dyads early after diagnosis have successfully prevented chronic emotional distress across several chronic illnesses including cancer and acute brain injury. Dyads with NDD could benefit from such interventions, however, they are limited. Because NDDs have symptom profiles that are distinct from other chronic illnesses, they require a unique framework and interventions. Given the limited dyadic interventions and unified symptoms across NDDs, a transdiagnostic framework may help to enhance scalability and efficiency. To address this problem, we developed a transdiagnostic framework that cuts across NDD physical and emotional diagnoses to inform cost-effective and sustainable NDD dyadic interventions.

METHODS

To develop this framework, we conducted: (1) a narrative review on dyadic adjustment and existent dyadic interventions for those with NDDs, and (2) integrated findings to develop our NDD transdiagnostic framework for dyadic interventions early after diagnosis.

RESULTS

Findings revealed no existent dyadic interventions for NDDs delivered shortly after diagnosis. Among available interventions, all were delivered later in disease progression, thereby focusing on dyadic challenges at more advanced stages. In addition, although research emphasized the influence of individual, dyadic, and contextual factors on dyads' early adjustment to NDDs, no conceptual model has been developed. Informed by theory and current research, we introduce an NDD transdiagnostic framework for couples' early biopsychosocial adjustment. This framework includes NDD specific: contextual factors, illness-related factors, individual and dyadic stressors, adaptive coping strategies, and dyads' resources.

CONCLUSIONS

Our NDD transdiagnostic framework can be used to inform early dyadic psychosocial interventions that cut across all NDDs. This approach has important implications for implementation and scalability.
