the Integrated Behavioral Model by Jennifer J Wohlwend Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Doctor of Philosophy Degree in Health Education The University of Toledo May 2013 The purpose of this study was to determine the factors that influence undergraduate college student use of emergency contraception as well as their level of knowledge and prevalence of using EC Understanding the factors that influence college student use of emergency contraception will inform development of intervention programs designed to increase its use, which may lead to lower rates of unintended/ unplanned pregnancies in this population Students at the 11 Midwestern institutions of the Mid-American Conference were surveyed with the help of faculty at each school A total of 1,553 surveys were completed with a response rate of 98.4% A small majority of students (63.5%) were female, white (75.3%) and age 18-21 years (80%) Students ranged from freshmen (23.8%) through seniors (13.8%), with sophomores as the largest group (32.6%) The majority were heterosexual (92.1%); not currently in a relationship (44.6%), with 34.1% were in a committed relationship Participants reported having had sexual intercourse at least once in their lifetime (78.9%) with 8.4% of sexually active students having experienced an unintended/unplanned pregnancy Students who have used emergency contraception in the last 12 months made up 18.1% of the students who also reported having had sexual intercourse at least once iii Knowledge of emergency contraception was not high in this group Knowledge was compared to emergency contraceptive use As knowledge increased, use of EC increased; as use of EC increased The Integrated Behavioral Model was used to investigate intention to use emergency contraception and predicted 50% of the variance in intention to use emergency contraceptives Each construct contributed a portion of variance and could be used in any future interventions to increase its use and decrease unintended/unplanned pregnancies for college students iv This dissertation is dedicated to my late sister, Donna Kruse Tischer, who would have whole-heartedly approved my topic; and my late father, Richard H Kruse, who would have been pleased that his daughter worked for her doctoral degree Acknowledgements I am extremely grateful to my dissertation chairman, Dr Tavis Glassman, who not only brought this topic to my attention, but enthusiastically worked with me from inception to completion; and through frustration and excitement I am also thankful to my committee members, Drs Dake, Jordan, Khuder and Kimmel, who each provided their own unique contribution to my study Without their dedication, hard work, and willingness to assist, completing my dissertation would have been much more difficult I also want to thank every faculty member of the Health Education Department, as each person provided invaluable input at some point along the way, from suggestions to encouragement Special thanks go to the faculty at each of the 10 Mid-American Conference schools who made it possible for me to collect my survey data Finally, I must thank my family, starting with my husband, Roger Wohlwend, who lived with me through the entire doctoral process He provided encouragement, was usually patient, and always got me to laugh even when it was a most difficult time My daughter, Melissa Buckland and her husband, Ryan Buckland, who lived with me through half of the battle and listened to me the other half, also provided comfort and encouragement Thank you to all of you Your assistance, encouragement and suggestions have not gone unnoticed nor unappreciated vi Table of Contents Abstract iii Acknowledgements
