What are the DSM‑5 criteria for diagnosing personality disorders?

DSM-5 Criteria for Personality Disorders

The DSM-5 defines personality disorders as enduring patterns of inner experience and behavior that deviate markedly from cultural expectations, are pervasive and inflexible, have onset in adolescence or early adulthood, are stable over time, and lead to clinically significant distress or impairment in functioning. 1

General Diagnostic Criteria

All personality disorders in DSM-5 must meet the following general criteria before a specific personality disorder can be diagnosed:

• Pattern characteristics: The enduring pattern must manifest in at least two of the following areas: 2, 3

  • Cognition (ways of perceiving and interpreting self, other people, and events)
  • Affectivity (range, intensity, lability, and appropriateness of emotional response)
  • Interpersonal functioning
  • Impulse control

• Pervasiveness: The pattern is inflexible and pervasive across a broad range of personal and social situations 2, 3

• Clinical significance: The pattern leads to clinically significant distress or impairment in social, occupational, or other important areas of functioning 2

• Stability and duration: The pattern is stable and of long duration, with onset traceable to at least adolescence or early adulthood 2, 4

• Exclusions: The pattern is not better explained by another mental disorder, substance use, medication, or another medical condition 2

DSM-5 Categorical Classification

The DSM-5 organizes 10 specific personality disorders into three clusters based on descriptive similarities: 2

Cluster A (Odd/Eccentric)

• Paranoid Personality Disorder: Pattern of distrust and suspiciousness 2, 3
• Schizoid Personality Disorder: Pattern of detachment from social relationships 2, 3
• Schizotypal Personality Disorder: Pattern of acute discomfort in close relationships, cognitive or perceptual distortions, and eccentricities 2, 4

Cluster B (Dramatic/Emotional/Erratic)

• Antisocial Personality Disorder: Pattern of disregard for and violation of the rights of others 5, 2, 3
• Borderline Personality Disorder: Pattern of instability in interpersonal relationships, self-image, affects, and marked impulsivity, including recurrent suicidal behavior and self-injury 1, 2
• Histrionic Personality Disorder: Pattern of excessive emotionality and attention seeking 2, 3
• Narcissistic Personality Disorder: Pattern of grandiosity, need for admiration, and lack of empathy 6, 2, 3

Cluster C (Anxious/Fearful)

• Avoidant Personality Disorder: Pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation 2, 3, 4
• Dependent Personality Disorder: Pattern of submissive and clinging behavior related to excessive need to be taken care of 2, 3
• Obsessive-Compulsive Personality Disorder: Pattern of preoccupation with orderliness, perfectionism, and control 2, 3, 4

DSM-5 Alternative Model (Section III)

The DSM-5 includes an alternative dimensional-categorical hybrid model for future study that represents a significant departure from traditional categorical diagnosis: 1

Level of Personality Functioning

This model requires assessment of impairments in personality functioning across two domains: 1

• Self functioning: Identity and self-direction
• Interpersonal functioning: Empathy and intimacy

Severity is rated on a continuum from little or no impairment (Level 0) to extreme impairment (Level 4) 1

Pathological Personality Traits

The alternative model evaluates five broad trait domains: 1

• Negative affectivity (vs. emotional stability)
• Detachment (vs. extraversion)
• Antagonism (vs. agreeableness)
• Disinhibition (vs. conscientiousness)
• Psychoticism (vs. lucidity)

Each domain contains specific trait facets that can be assessed dimensionally 1

Critical Diagnostic Considerations

Lack of insight is a core feature of personality disorders and should not preclude diagnosis. 1, 6 Self-report measures have minimal utility due to impaired insight, making structured interviews with multiple informants essential 1, 6, 7

Informant discrepancies are expected and diagnostically informative rather than invalidating. 1, 6 Gathering collateral information from family members, caregivers, or others who observe the interpersonal dysfunction is crucial for accurate diagnosis 6, 7

The diagnosis requires demonstration of pervasive dysfunction across multiple contexts, not just isolated problematic behaviors in specific situations 7 However, research indicates that dysfunction may not be equally severe across all interpersonal domains for every personality disorder 7

Common Diagnostic Pitfalls

• Do not rely solely on patient self-report: Structured clinical interviews with collateral informants are necessary 1, 6
• Do not confuse state symptoms with trait patterns: Personality disorders represent stable, long-standing patterns, not episodic symptoms 4, 8
• Do not diagnose based on single-domain impairment: The pattern must be evident across multiple areas of functioning 2, 7
• Do not overlook the stability criterion: While trait expression may fluctuate in intensity, the underlying pattern should be traceable to adolescence or early adulthood 4, 8
• In elderly patients, consider organic causes: New-onset personality changes in older adults suggest neurological disease rather than personality disorder 3
