Developing NANDA-I, NOC, and NIC Linkages for the Diagnosis of Excessive Loneliness.

was identified as the primary NOC outcome for evaluating resolution of the diagnostic focus, operationalizing the severity of emotional, social, and existential signs and symptoms of isolation. Additional NOC outcomes addressed defining characteristics (n = 20) and related factors (n = 10) across emotional, psychosocial, physical, cognitive, and safety domains. A total of 47 NIC interventions were identified, emphasizing meaningful participation, adaptive coping, and personalized care.ConclusionsThe resulting NNN linkage provides a structured, outcome-oriented framework for assessing and managing excessive loneliness. It enhances diagnostic accuracy, supports individualized interventions, and makes nursing contributions visible and measurable within interdisciplinary care.
