Which of the following features is commonly associated with Borderline Personality Disorder?

Borderline Personality Disorder (BPD) is characterized by a pattern of intense and unstable interpersonal relationships. Individuals with BPD often experience an extreme idealization of others, followed by feelings of devaluation, which can lead to tumultuous relationships. This instability in relationships is a hallmark feature of the disorder, reflecting a deep-seated fear of abandonment and intense emotional responses to perceived threats in relationships.

In contrast, stable emotional states do not characterize BPD, as individuals typically experience significant mood swings and emotional dysregulation. Lack of impulsivity is also not a feature of BPD; rather, people with this disorder often act impulsively in ways that can be self-destructive, such as engaging in risky behaviors. Additionally, having a high tolerance for stress is not typical for those with BPD, as individuals often struggle to cope with stress and may experience heightened emotional responses or crises in stressful situations.

Therefore, the intense interpersonal relationships that fluctuate between extremes of closeness and distance are a core aspect of the disorder, making this choice the most accurate representation of a commonly associated feature with Borderline Personality Disorder.
