Which PD is best described as instability in relationships and self-image with emotional volatility?

• A. Narcissistic PD
• B. Histrionic PD
• C. Borderline PD
• D. Paranoid PD

Answer: (C)

Instability in relationships and self-image with emotional volatility is a hallmark of Borderline Personality Disorder. People with this pattern typically experience intense, unstable relationships that swing between idealization and devaluation. They may have an unstable sense of self, with rapidly shifting self-image and feelings of emptiness. Emotions change quickly and intensely, moving from one extreme to another within a short period. A strong fear of abandonment often drives frantic or impulsive behaviors aimed at avoiding real or imagined rejection, and impulsivity can appear in multiple areas of life. This combination—tickle of relationship turbulence, an unstable sense of self, and rapid mood swings—distinguishes it from other personality patterns. For example, Narcissistic Personality Disorder emphasizes grandiosity and a need for admiration; Histrionic Personality Disorder centers on attention-seeking and dramatic affect; Paranoid Personality Disorder involves pervasive distrust and suspicion. Thus, the described pattern best fits Borderline Personality Disorder.
