Abstract

Context: Despite the benefits of advance care planning (ACP), cancer patients rarely engage in ACP. ACP is a process that parallels health behavior change. This makes the Transtheoretical Model of Health Behavior Change (TTM) an important framework for understanding how to increase ACP among cancer patients. Objectives: This study aimed to systematically review ACP interventions for cancer patients by 1) categorizing ACP intervention components according to the stages and processes of behavior change in the TTM, 2) conducting a gap analysis among the categorized components, and 3) identifying patterns between the categorized intervention components and the intervention outcomes. Methods: PubMed, CINAHL Plus, MEDLINE, Cochrane Library, and Web of Science databases were searched for articles related to ACP and cancer. ACP intervention components were abstracted, assessed for theoretical relevance, organized according to the stages and process of change in the TTM, and then synthesized. Results: The search produced 4604 articles, with 25 meeting criteria for review. Most intervention components targeted the precontemplation and contemplation stages of change, with fewer targeting preparation, action, or maintenance. Multiple processes of change were not addressed. Interventions that resulted in ACP engagement tended to take an interdisciplinary approach to implementation and consisted of multiple consultations staged over time. Conclusion: ACP likely requires “high touch” interventions to induce behavior change. ACP interventions that are stage-matched, use diverse mechanisms to engage ACP (i.e., processes of change), address ACP as a process, and monitor engagement across the illness trajectory are needed for cancers patients and their caregivers.
