Final answer:
Self-mutilation is most commonly associated with Borderline Personality Disorder (BPD), where individuals engage in self-harm as a coping mechanism to manage overwhelming emotions.
Step-by-step explanation:
Self-mutilation, also known as self-harm, is most commonly associated with Borderline Personality Disorder (BPD). Those with BPD often struggle with managing emotions and may resort to self-injurious behaviors, including cutting or burning, as a coping mechanism. Self-mutilation can be a way to express difficult or overwhelming feelings, or to exert a sense of control over one's body when internal emotions seem uncontrollable.
Although self-harm can occur in various mental health conditions, it is particularly prevalent among individuals with BPD, as indicated by research, including a review by White, C. N., Gunderson, J. G., Zanarani, M. C., & Hudson, J. I. (2003). It's important to note that while BPD is often associated with these behaviors, not everyone with BPD will engage in self-mutilation.
