Sibling abuse is the most prevalent form of interpersonal abuse in the United States today. Yet despite this widespread problem, it is alarming how much we truly do not know about this issue and how little has been done to remedy it. Little is known about this form of abuse because of the underreported accounts. Also, even less is known about the reports of sibling abuse by Seventh-day Adventist college students. The sample consisted of 32 students from Southern Adventist University. Of the 32 participants, the majority were female (53%), 13 identified as freshmen, four identified as sophomores, three identified as juniors, and 12 identified as seniors. The average participant age was 21.26. The design of this study was a non-experimental study using survey methodology, the K. Couser Sibling Interaction Instrument (KCSII) survey. The first hypothesis tested in this study was that there are gender differences of sibling bullying tendencies among Southern Adventist University students. The second hypothesis tested was that students who are younger (birth order) would report higher rates of being the victim of sibling abuse. In this study, there were no statistically significant results. Results show that men are more likely than women to report higher frequencies of being the bully and witnessing sibling abuse. The limitations of this study were time, the sample of convenience, and the narrow definition of sibling abuse. Despite its limitations and weaknesses this study is important to psychology because research has not been conducted regarding religiosity and personality and its role in sibling abuse.
