Moreso than in most medical problems and health crisis situations, leaders of many and diverse disciplines repeatedly cite “changes in behavior” as the mainstay of addressing the challenges of the Covid 19 pandemic. Given the lack of preventative, protective, and treatment modalities, the importance of behavior and habit change by individuals and society becomes the most prominent “tool in the box,” and allows for empowerment of individuals, families, organizations, and societies. This presentation highlights ways in which behavioral principles and techniques, especially when integrated with relevant principles of medicine and public health, can, and need to, be applied by clinicians and non clinicians to promote desired behaviors/habits including mask/PPE use (and techniques) and practicing social distancing, as well as remembering to NOT do many things we habitually do like shaking hands and holiday family gatherings. It applies as well to "private" behaviors of attitudes, opinions, knowledge (reality of the illness, safety of vaccines). The current pandemic serves as yet another opportunity for those most skilled in the principles and techniques of the management of behavior and development of habits to showcase the power of the discipline in making substantive desirable impacts on many phases of the COVID 19 pandemic, and the people affected by it.
