This unique multidisciplinary volume examines the dynamics of behavioral change and its maintenance, from the individual to the wider domains of public policy. Coverage traces how change may be achieved, sustained, or derailed, as well as underlying neurobiological, behavioral, and social processes that fuel unhealthy and risky behaviors. Contributors offer a wide range of prevention and intervention strategies for supporting positive health habits from improved food choices to abstinence to compliance with treatment. These mechanisms are then transferred to the societal level in studies of evolving public perception of salient issues such as climate change, gender disparities, and drug policy.
