Whether viewed as a domain-specific behavior or as an enduring tendency, procrastination is a common form of self-regulation failure that is increasingly recognized as having implications for health-related outcomes. Central to procrastination is the prioritization of reducing immediate negative mood at the cost of decisions and actions that provide long-term rewards, such as engaging in health behaviors. Because people tend to procrastinate on tasks they find difficult, unpleasant, or challenging, many health-promoting behaviors are possible candidates for procrastination. As modifiable risk factors for the prevention of disease and disability, health behaviors are often the target of health risk communications aimed at health behavior change and reducing health procrastination. Research has consistently demonstrated the deleterious effects of chronic procrastination on health outcomes, including poor physical health, fewer health promoting behaviors, and higher stress in healthy adults and those already living with a chronic health condition. Examining the factors and psychological characteristics associated with chronic procrastination can provide insights into the processes involved in procrastination more generally, as well as the qualities of the health messages that can promote or prevent procrastination of the targeted behaviors. Low future orientation, avoidant coping, low tolerance for negative emotions, and low self-efficacy need to be considered when designing effective health risk communications to reduce procrastination of health behaviors. Yet, health risk communications aimed at reducing procrastination of important health behaviors such as healthy eating, regular physical activity, screening behaviors, and cessation of risky health behaviors often use fear appeals to motivate taking protective actions to reduce health risks. Such approaches may not be effective because they amplify the negative feelings towards the health behaviors, which can engender maladaptive coping responses and motivate procrastination rather than adaptive responding. This is especially likely among individuals prone to procrastination more generally, or specifically with respect to health. Health risk communication approaches that minimize the negative emotions associated with risk messages and instead highlight short-term benefits of engaging in health behaviors may be necessary to reduce further health behavior procrastination among individuals prone to this form of self-regulation failure.
