Childhood trauma and borderline personality disorder traits: A twin Study

[WorkingOnItToo]

This research may be of interest to those parents who’s BPD children falsely accuse them of “causing trauma” (note word *falsley*) and insist that their BPD is caused purely by you as their insufficient parent.

Here is the link https://psycnet.apa.org/record/2022-47576-001 but I’ll copy and paste the abstract below:

A discordant twin design was utilized to examine the potentially causal effects of childhood trauma (CT; i.e., emotional abuse, physical abuse, sexual abuse, and witnessing violence) on borderline personality disorder traits (BPD traits) in early adulthood. The participants were 2,808 twins between 17 and 23 years from the Oslo University Adolescent and Young Adult Twin Project. BPD traits were assessed by the Structured Interview for DSM–IV Personality (SIDP-IV), and CT was assessed using the Childhood Trauma Interview (CTI). BPD traits (h² = .50) and CT (h² = .33–.69) were both found to be moderately heritable. Small but statistically significant associations between CT and BPD traits were found in the total sample. After controlling for shared environmental and genetic factors in the discordant twin pairs, the analyses showed little to no evidence for causal effects of CT on BPD traits. The results indicated that the associations between CT and BPD traits stem from common genetic influences. These findings are inconsistent with the widely held assumption that CT causes the development of BPD.

Our objective is to better understand the struggles our child faces and to learn the skills to improve our relationship and provide a supportive environment and also improve on our own emotional responses, attitudes and effectiveness as a family leaders

Here is Google's AI (experimental) summary of this article - with the following disclaimer "Generative AI is experimental. Info quality may vary.":

The study Childhood trauma and borderline personality disorder traits: A discordant twin study was published in the Journal of Psychopathology and Clinical Science in 2022.

 The study examined the potential causal effects of childhood trauma on borderline personality disorder (BPD) traits in early adulthood.

 The study used a discordant twin design, which means that one twin is healthier than the other.

 The study included 2,808 twins.

The study used the Childhood Trauma Interview, a structured interview based on self-report. The study found small but statistically significant associations between childhood trauma and BPD traits.

Childhood trauma includes: Emotional abuse, Physical abuse, Sexual abuse, Witnessing violence.

People with BPD are 13 times more likely to report childhood trauma than people without any mental health problems. People with BPD also have especially high rates of childhood sexual trauma.

Twin studies have shown that 42% of variation in BPD is caused by genetics and 58% is caused by other factors, such as the environment. Two genes, DPYD and PKP4, have been identified as increasing a person's risk of developing BPD.
