Erika Litvin Bloom is a behavioral/social scientist at RAND Corporation. Her research has focused primarily on tobacco and other substance use, including behavioral treatment development and weight and body image concerns in the context of tobacco use and cessation. She also has broad interests in increasing effectiveness, access to, and uptake of substance use treatment; digital health and health care technology; and health behavior change theory and processes. She is currently the Co-Principal Investigator of a National Institute on Drug Abuse-funded Fast Track Small Business Innovation Research (SBIR) grant with a goal to develop and test a smartphone-delivered smoking cessation program with social gaming and financial incentive components. In other recent projects, she developed and tested a distress tolerance treatment for women who were concerned about gaining weight after quitting smoking and a contingency management treatment targeting prevention of weight gain after smoking cessation.
