Abstract: This narrative review outlines the potential benefits of supporting clients to successfully change existing patterns of behavior in the context of wound care. In acknowledging the complexities involved in changing deeply ingrained patterns of behavior, the case for developing interventions based on evidence is presented. The evidence-based psychological targets, which are recommended for inclusion in behavior change interventions, are outlined together with their theoretical derivatives. An example of an intervention developed using evidence-based techniques is presented. The challenges of progressing understanding and developing successful interventions in the context of wound care are discussed.

The potential benefits of promoting successful behavior change in the context of wound care are considerable. An example of this is the challenge of optimizing outcomes for patients with a diabetic foot ulcer. The road to recovery and the maintenance of good health require the patient to modify many aspects of behavior, which can include patterns of eating, smoking cessation, or the maintenance of the most recent attempt to quit, the need to engage in regular self-examination, attendance at podiatry check-ups, and wearing the necessary protective footwear.
Intuitively, it would be reasonable to expect that people would value their health highly, and consequently, would be responsive to straightforward messages about the benefits of behavior change and the serious health risks associated with existing patterns of behavior. However, reality is much more complex,1 and the low rate of success associated with most approaches to health behavior change has preoccupied researchers recently.
As long ago as 400 BC, Hippocrates is credited with noting that “Everyone has a doctor in him or her; we just have to help it in its work.”1 It was not until relatively recently, however, that the true complexity of behavior change and the costs associated with failing to achieve it have been recognized and highlighted in policy documents (eg, the UK Government White Paper “Choosing Health” published in 2004).2
Although an acceptance of this complexity is a recent phenomenon in the research literature, it is well recognized among practitioners in wound care and those who manage chronic conditions. These professionals know better than most that for the majority of patients simple approaches (eg, the provision of information about the benefits and risks of certain behaviors) are not sufficient to influence and maintain change in target behaviors.
Some of the factors identified as contributing to existence of patterns of health-related behaviors that lead to greater levels of risk for morbidity and mortality, and also to the likelihood that behavior change interventions will succeed, are not amenable to change.3 These factors include sociodemographic variables (eg, gender, age, socioeconomic status, culture), and environmental barriers to change (eg, lack of availability, or cost of healthy foods). A change in a range of psychological factors relevant to health-related risk behaviors, which include beliefs and cognitions, is both possible and achievable. Although it is widely accepted that optimal outcomes would result from simultaneous interventions at population, local community, and individual levels, it is also accepted that this is rarely possible or achievable.
