    Journal: Oncol Nurs Forum; 2009 Jan; 36(1):E20-30. PubMed ID: 19136328.
    Abstract:
    PURPOSE/OBJECTIVES: To consolidate the literature and provide a model to explain the links among uncertainty, post-traumatic stress syndrome, and health behaviors in adolescent and young adult childhood cancer survivors. DATA SOURCES: A systemic review of related literature and theory was used for the proposed model. The literature pertaining to the Uncertainty in Illness Theory, childhood cancer late effects, post-traumatic stress, and health behaviors was reviewed and critiqued from three data sets from 1979-2007: MEDLINE, PsycInfo, and CINAHL. Key words used for the search were uncertainty and post-traumatic stress as well as health behaviors, including smoking, alcohol use, unsafe sex, sunscreen use, and physical inactivity. DATA SYNTHESIS: Childhood cancer survivors living with chronic uncertainty may develop a new view of life and, as a result, adopt more health-promotion behaviors and engage in less health-risk behaviors. However, survivors living with chronic uncertainty may generate symptoms similar to post-traumatic stress disorder and, therefore, adopt fewer health-promotion behaviors and engage in more health-risk behaviors. CONCLUSIONS: The uncertainty that pervades the childhood cancer experience can lead to the development of symptoms that resemble those of post-traumatic stress. The symptoms can interfere with the adoption of healthy lifestyle behaviors and avoidance of health-risk behaviors. IMPLICATIONS FOR NURSING: The theoretically derived model outlined in this article can be used to guide clinical interventions and additional research into the health behaviors of childhood cancer survivors.
