Understanding Self-Defeating Personality Disorder: Causes & Contributing Factors

The exact causes of self-defeating personality disorder are unknown, but several factors are thought to play a role, including:

Genetics: Personality traits, including the tendency to be self-defeating, can be inherited.

Childhood experiences: People who grow up in chaotic, abusive, or neglectful homes may be more likely to develop self-defeating personality disorder.

Cultural influences: Some cultures value self-sacrifice and modesty, which can contribute to the development of self-defeating personality disorder.

Brain abnormalities: Studies have found that people with self-defeating personality disorder may have abnormalities in the part of the brain involved in regulating emotions, such as the amygdala and hippocampus.

Trauma: People who have experienced trauma, such as physical or sexual abuse, may be more likely to develop self-defeating personality disorder.
