A 25-year-old female presents with a history of intense, unstable relationships, recurrent suicidal gestures, chronic feelings of emptiness, and impulsive spending sprees. She often describes her mood as rapidly shifting from extreme elation to profound despair within hours. Which of the following DSM-5 criteria for Borderline Personality Disorder is *least* likely to be present in this patient based on the provided description?

Explanation

The vignette describes several core features of Borderline Personality Disorder (BPD), including unstable relationships (suggesting fear of abandonment), recurrent suicidal gestures (impulsivity/self-harm), chronic feelings of emptiness (identity disturbance), and affective instability (rapidly shifting mood). Frantic efforts to avoid abandonment are a hallmark of BPD and often underlie unstable relationships. Identity disturbance and affective instability are explicitly mentioned or strongly implied. Grandiosity and a pervasive pattern of excessive admiration-seeking are characteristic features of Narcissistic Personality Disorder, not Borderline Personality Disorder. While comorbidity can exist, these specific traits are not part of the core BPD diagnostic criteria.
