Using Dyadic Modeling in Nursing Research: Introduction of Theory and Application.

Use of dyadic modeling in nursing has theoretical and practical importance, as the interpersonal processes related to health behaviors can be captured. Theoretical models focusing on dyadic coping with chronic illness and illness management are established in family nursing. However, few studies utilized dyadic designs in empirical research, as most studies are patient-centric or care partner-centric. With theoretical elaborations and examples, we first review how conventional health models have been extended using a dyadic perspective and then briefly review the major dyadic frameworks in nursing. Five frequently used dyadic models are described with examples from health and nursing research fields. Statistical applications and cultural considerations are reviewed. We conclude that dyadic modeling provides a useful lens for nursing research but continues to be underutilized.
