Dr. Eusebio Alvaro is a Research Professor in the Division of Behavioral and Organizational Sciences at Claremont Graduate University and Co-Director of the Health Psychology & Prevention Science Institute.  Dr. Alvaro received a doctorate in Communication (specializing in Social Influence) with a minor in Social Psychology and a Masters of Public Health in Health Education and Promotion from the University of Arizona. Prior to coming to CGU he served as Director of the Health Informatics Program in the Center for the Management of Information at the University of Arizona and Director of the Health Communication Research Office at the Arizona Cancer Center.

His basic research centers on the study of social influence processes with an emphasis on biased message processing, resistance to persuasion, indirect effects of persuasive messages, and mechanisms by which minorities can achieve change. His applied research and evaluation activities involve studying persuasion in the context of health promotion, disease prevention, and medicine with a particular focus on the development and testing of mass media messages targeting health behavior change. These activities all draw on behavioral science theories in order to determine how negative health behaviors may be overcome and positive behaviors encouraged while also feeding back into theory development and refinement.

Dr. Alvaro’s applied work has been consistently funded by a number of federal agencies since 1998. He is currently funded by the Health Resources and Services Administration (HRSA), the National Institute on Drug Abuse (NIDA), and other federal organizations. One stream of his current work involves the evaluation of mass media and community outreach efforts to promote organ donation in both the general population and among Hispanics. These projects have a theoretical basis in work regarding the attitude-behavior relationship and are designed to assess efforts at transforming positive organ donation attitudes into organ donation registration behavior. An important part of this work also involves investigating approaches to educate low literacy populations on living organ donation – addressing both knowledge and self-efficacy deficits. This research crosses the disciplines of Social Psychology, Prevention Science, Clinical Medicine, Marketing, and Communication.

A second major stream of funded applied research involves developing and assessing the impact of drug prevention messages for adolescents. This research has taken the form of secondary analyses of nationally representative datasets originally developed to assess effects of a national drug prevention campaign as well as original field experiments testing theoretically derived messages. A key aspect of these efforts is determining which messaging approaches work best to minimize resistance to change. This work crosses the disciplines of Social Psychology, Prevention Science, and Marketing.

Through his formal education and training in Communication, Social Psychology, and Public Health, Dr. Alvaro has been exposed to varied theoretical and methodological approaches. As such, he has a strong commitment to drawing on different disciplines and collaborating with specialists in different domains in order to address issues of common concern. As evidenced by his research activities, a key guiding value for Dr. Alvaro is the use of theory-based research and evaluation in applied contexts in order to have a real impact on issues that matter.

siegelDr. Jason T. Siegel is an Associate Professor at Claremont Graduate University and Co-Director of the Health Psychology & Prevention Science Institute. His research involves the application of social psychological theories to the health domain. His work commonly focuses on enhancing interventions seeking to influence health behavior. Dr. Siegel’s work typically focuses on adolescent substance use and organ donation. He has also conducted research in the domain of depression and adolescent diabetes. Regarding substance use, Dr. Siegel has investigated adolescent inhalant use, marijuana use, and tobacco use. In regards to inhalant use, Dr. Siegel has investigated the role of socio-personal expectations on inhalant use intentions. He has also investigated the utility of different message features for enhancing the effectiveness of Public Service Announcements. His marijuana research focuses on investigating differences between resolute non-users and vulnerable non-users. Dr. Siegel’s tobacco research has focused on ways of maximizing campaigns targeting adolescent tobacco use. Dr. Siegel’s work on substance abuse research has been published in journals such as Prevention Science and Journal of Adolescent Health. The majority of Dr. Siegel’s research in organ donation investigates the reasons behind the lack of attitude-behavior consistency in regards to organ donation and organ donor registration. In relation to the lack of attitude-behavior consistency, Dr. Siegel, along with his colleague Eusebio Alvaro, recently developed the IIFF Model of organ donor registration behavior. Moreover, Dr. Siegel has implemented media and community campaigns seeking to increase organ donor registration behavior. Dr. Siegel’s organ donation research has been published in outlets such as Health Psychology, Journal of Health Communication, and Psychology, Health and Medicine. Moreover, Dr. Siegel recently co-edited a book on organ donation, Understanding Organ Donation: Applied Behavioral Science Perspectives.
