Borderline personality disorder is a mental health condition characterised by intense mood swings, impulsive behaviour, identity disturbances, and self-harming tendencies. Many individuals with the diagnosis also struggle with anxiety and depression.

There are various treatment methods available, but determining which ones are most effective is challenging. Storebø’s research focuses on improving the evaluation of psychotherapeutic treatments to provide more precise answers on what works best.

What has Storebø found?
By reviewing nine key scientific studies, he has identified several issues in previous research. These issues make it difficult to trust the results and make well-informed decisions about treatment.

For example, he has examined:

Bias (systematic errors in research that can affect the results)
Differences between patient groups that make it difficult to compare studies
How control groups (different types of comparison groups in clinical trials) influence research outcomes
The need for more precise methods to ensure that treatment recommendations are based on solid evidence
His research highlights the need for better and more rigorous studies to ensure that patients receive the best possible treatment.
