Health behavior change refers to the process by which individuals modify their habits and actions in order to improve their health and well-being. This field of research explores the factors that influence behavior change, such as motivation, self-efficacy, social support, and environmental influences. Researchers in this area often design and evaluate interventions aimed at promoting healthy behaviors, such as exercise, healthy eating, and smoking cessation. The ultimate goal of health behavior change research is to develop effective strategies for helping individuals adopt and maintain healthier lifestyles.
