"This is an area of research needing more investigation. Mackey, Fromuth, and Kelley (2010) did a small study with about 145 undergraduates asking about sibling bullying. Their results indicated that those who considered themselves to be bullied by a sibling when they were children continued to experience anxiety. There are questions that still must be addressed. When a child has been bullied by a sibling or more than one sibling, are there continuing effects into adulthood? The studies above indicate that children bullied by their siblings are more likely than those who have not been bullied to experience anxiety, depression, behavioral problems, and self-harming behaviors needing clinical intervention. Do these issues carry over to other stages of life? What happens to these sibling relationships once they are adults? Is all forgotten or forgiven? Or is there always a sense of mistrust? Bowes et. al. (2014) found that children who were bullied by their siblings were more likely to be bullied by peers and, as we have discussed in other sections of the book, the impact of peer bullying does last a lifetime. At this point in time, most have figured out that peer bullying at school and in the community is not acceptable, but sibling bullying remains an arena where adults still take a hands-off attitude."
