According to DSM-5, which statement is required for the general diagnosis of a personality disorder?

• A The pattern must be episodic, lasting at least two weeks at a time
• B The pattern must appear for the first time after the age of 40
• C The patient must lack insight into the pattern throughout life
• D The pattern must have its onset no later than adolescence or early adulthood and be stable and pervasive across personal and social situations ✓

Explanation

D personality disorder is an enduring, inflexible, pervasive pattern of inner experience and behaviour that deviates markedly from cultural norms, is manifest in at least two areas (cognition, affect, interpersonal functioning, impulse control), leads to distress or impairment, is stable and of long duration, and has an onset traceable back to adolescence or early adulthood. D pattern beginning for the first time in midlife or later suggests another cause such as substance use or a medical condition, not a personality disorder.
