AN ABSTRACT OF THE THESIS OF Donna A Champeau for the degree of Doctor of Philosophy in Public Health presented on November 23, 1994. Title: Factors Influencing Individual Attitudes Toward Voluntary Active Euthanasia and Physician Assisted Suicide. Redacted for privacy Abstract approved: Rebecca J. Donate lle Issues of right to life, as well as death have surfaced as topics of hot debate. In particular, questions about when and if individuals have the right to end their own lives have emerged and gained considerable attention as health policy issues having the potential to affect all Americans.. The purpose of this study was to identify the factors that are most likely to influence an individual's decision to support or not support voluntary active euthanasia (VAE) and physician assisted suicide (PAS) in specific medical situations. This study also examined the differences in medical vignettes by various demographic and attitudinal factors. Data were collected from a sample of classified staff members at two institutions of higher learning in Oregon. A survey was used to collect all data. Paired sample T- tests, stepwise multiple regression analysis and repeated measures multiple analysis of variance (MANOVA) were used to analyze the data. Based on survey results, there were significant differences in attitudes toward PAS and VAE for each medical vignette. Religious beliefs, fear of dependency, and fear of death were the most powerful predictors of individual support for PAS in each medical situation. In the case of VAE, there were differences in support on each medical situation in terms of the most powerful predictors: fear of dependency and religious beliefs for the cancer vignette, fear of dependency, religious beliefs, and age for the ALS vignette, and religious beliefs and fear of dependency for the paralysis vignette. The repeated measures MANOVA revealed that in general, the older the individual was, the less likely they were to support PAS or VAE. However, women over age 66 in this study were more likely to support VAE than were the males age 66 and over. Males in the 51-65 year old category were more supportive of VAE than females in this age category. Also, those who were more fearful of death were more likely to have a higher level of support for VAE. In all three vignettes (Cancer, Amyotrophic lateral sclerosis (ALS), and paralysis) for both PAS and VAE, there was a significantly different level of support measured on a seven point Likert scale.

Champeau, Author ACKNOWLEDGMENTS I wish to extend my gratitude to all the classified staff members that participated in this study. Their willingness to take the time to answer the questionnaire was greatly appreciated and made the completion of this study possible. For providing partial financial assistance I would like to acknowledge the College of Health and Human Performance at Oregon State University. This assistance was extremely helpful. Thanks are also given to my colleagues, and friends at Oregon State University for their encouragement and support throughout the final preparation of this thesis. A special thanks is given to my dear friend and associate graduate student, Jessica Hendersen for the encouragement and support that she so unselfishly gave during this entire process. For statistical assistance I would like to thank Laura Bond at Boise State University and Cheryl Kelber at the University of Milwaukee Wisconsin for their advice and suggestions in the analysis of data collected. A very special thanks to Laura for her willingness to provide many suggestions and much advise. I sincerely thank the members of my graduate committee, Drs. Rebecca Donatelle, Jan Hare, Anna Harding, Ray Tricker, and Jeff McCubben, for their valuable input and interest in this study. I am especially appreciative of the contributions of Dr. Jan Hare, my co-chair on this project, who gave generously of her time and counsel. Her expertise and understanding throughout this project have been invaluable to me. I would also like to extend the biggest thanks to my major professor, Dr. Rebecca Donate lle, who has given an incredible amount of her time and expertise not only on the completion of this final project but also throughout my entire doctoral study. Her mentoring and guidance provided me with experiences that were extremely helpful in my development as a health professional. Finally, I would like to thank my family for their unceasing encouragement, love, and understanding. I am especially thankful to my parents and my brother Ryan who have always stood behind me and have been a continual source of inspiration to me.
