What is a key characteristic of clients with borderline personality disorder as reflected in their behavior?

Clients with borderline personality disorder often experience intense and unstable emotions, leading them to engage in various behaviors that may be seen as 'acting out'. This behavior is typically a response to overwhelming anxiety, stemming from deep-seated internal conflicts such as fear of abandonment and identity disturbances. Acting out serves as a maladaptive coping mechanism for these individuals, as it allows them to express their distress and anxiety in a way that is more external and observable.

This characteristic reflects the turmoil they experience in managing their emotions and relationships. Unlike stable behaviors, which could indicate a more regulated emotional state, the tendency to act out highlights the significant challenges these clients face in managing their interpersonal relationships and emotional responses. Their impulsive actions and variable moods further complicate their situations, often leading to difficulties in maintaining consistent and supportive relationships.
