Physical inactivity is an important contributor to the development of numerous chronic conditions and alone is an independent risk factor for diabetes, cardiovascular disease, and depression and yet, most Americans consistently fail to achieve the recommended amount of physical activity. As part of Project HealthDesign, we designed and prototyped a personal health record application (PHA) that delivers and supports a highly individualized, behaviorally based lifestyle physical activity intervention for sedentary adults. Through a user centered design approach, we engaged consumers, health care providers, and personal trainers for multiple facilitated group discussions and structured interviews to determine their needs and wants related to an activity PHA. The PHA was developed to include elements of evidence-based approaches which help participants adopt cognitive and behavioral skills such as goal-setting, self-monitoring, accepting social support, cognitive restructuring, contingency management, decisional balance, and relapse prevention. This PHA demonstrated the potential for research-based behavioral interventions to be delivered via a web portal. This finding is important for both consumers and their providers who have the desire to implement physical activity recommendations, but lack the tools to facilitate or undertake such interventions.
