Individuals are left with physical and emotional scars that can last a lifetime. Abuse during childhood can be detrimental to a person’s psychological adjustment during adolescence and adulthood. We sought to answer the research question, “Does child abuse positively correlate with Borderline Personality Disorder?” We analyzed 12 studies that compared different types of child abuse and the effects it has on Borderline Personality Disorder (BPD). For these 12 studies, the average effect size was (r = .22). Emotional abuse had the highest correlation (r = .26) and then sexual abuse (r = .22). The other moderator variables did not have significant results. The average effect size is a moderate size, and it does show that there is an important correlation between abuse and BPD. 3 Results 4 Conclusion It was found that there is a positive correlation between abuse and BPD. Emotional abuse has the highest correlation value of r = .26. Although correlation does not establish causation, this research does suggest that all types of abuse can have lasting psychological harm.
