Dr. Zimet is a Clinical Psychologist and Professor in the Department of Pediatrics. Since he arrived at IU School of Medicine in 1993 he has guided an extensive and multi-faceted behavioral and social science research program focused on attitudes about and determinants of vaccination with a particular focus on human papillomavirus (HPV) vaccination. Dr. Zimet's research also has involved randomized clinical trials designed to evaluate the effects of behavioral interventions on hepatitis B virus (HBV) and HPV vaccine uptake and on acceptance of HIV testing. In addition, through his nearly 15 year involvement in the Adolescent Medicine Trials Network (ATN) for HIV/AIDS Interventions. Dr. Zimet has expanded his research focus to examine consent and ethical factors related to recruitment of adolescents into biomedical HIV prevention clinical trials. Dr. Zimet's research has been funded by NIH, CDC, and private industry. He collaborates with researchers throughout the U.S. and from several other countries who represent many different disciplines including health marketing, health communication, medicine, psychology, biostatistics, nursing, and public health. Dr. Zimet has served as a research mentor to physician fellows, medical students, pediatric residents, pre- and post-doctoral fellows in psychology, social work, health behavior, and nursing, and junior faculty across several departments and schools. In the 1980s, Dr. Zimet and several colleagues (including his mother) developed the Multidimensional Scale of Perceived Social Support (MSPSS), a measure that is widely used in research worldwide and has been translated into over 35 languages.
