Analysis of the Tidal Model and Its Implications in Late-Life Suicidality

Late-life suicide is a public health issue in the United States, and recent CDC data show that the number of deaths related to suicide in older adults continue to increase. Still, few researchers focus on a theoretical framework for the clinical assessment and care of older adults at risk for suicide. We performed a review and critical analysis of the Tidal Model, using Fawcett and DeSanto-Madeya's framework, to increase our understanding of the clinical presentation of older adults with suicidal ideation and present strategies for caring for this population. The Tidal Model is a well-structured theory with relevant concepts and propositions founded on a highly patient-centered and pragmatic approach that facilitates its application in late-life suicidality. The model provides a framework for nursing and healthcare practice in psychiatry and mental health with goals and boundaries that help promote a better assessment of the clinical picture of older adults with suicidal ideation.
