Borderline Personality Disorder – DSM-5 and ICD-11 Diagnostic Criteria
The essential features of a personality disorder are impairments in personality (self and interpersonal) functioning and the presence of pathological personality traits.
According to the DSM- 5, to diagnose a borderline personality disorder, the following criteria must be met:
A. Significant impairments in personality functioning manifest by:
Impairments in self-functioning (a or b):
- Markedly impoverished, poorly developed, or unstable self-image, often associated with excessive self-criticism; chronic feelings of emptiness; dissociative states under stress.
- Instability in goals, aspirations, values, or career plans.
Impairments in interpersonal functioning (a or b):
- Compromised ability to recognise the feelings and needs of others associated with interpersonal hypersensitivity (i.e., prone to feel slighted or insulted); perceptions of others selectively biased toward negative attributes or vulnerabilities.
- Intense, unstable, and conflicted close relationships, marked by mistrust, neediness, and anxious preoccupation with real or imagined abandonment; close relationships often viewed in extremes of idealization and devaluation and alternating between over-involvement and withdrawal.
B. Pathological personality traits in the following domains:
1. Negative Affectivity, characterized by:
a. Emotional liability:
- Unstable emotional experiences and frequent mood changes; emotions that are easily aroused, intense, and/or out of proportion to events and circumstances.
- Intense feelings of nervousness, tenseness, or panic, often in reaction to interpersonal stresses; worry about the negative effects of past unpleasant experiences and future negative possibilities; feeling fearful, apprehensive, or threatened by uncertainty; fears of falling apart or losing control.
c. Separation insecurity:
- Fears of rejection by – and/or separation from – significant others, associated with fears of excessive dependency and complete loss of autonomy.
- Frequent feelings of being down, miserable, and/or hopeless; difficulty recovering from such moods; pessimism about the future; pervasive shame; feeling of inferior self-worth; thoughts of suicide and suicidal behaviour.
2. Disinhibition, characterized by:
- Acting on the spur of the moment in response to immediate stimuli; acting on a momentary basis without a plan or consideration of outcomes; difficulty establishing or following plans; a sense of urgency and self-harming behaviour under emotional distress.
- Engagement in dangerous, risky, and potentially self-damaging activities, unnecessarily and without regard to consequences; lack of concern for one‟s limitations and denial of the reality of personal danger.
3. Antagonism, characterized by:
- Persistent or frequent angry feelings; anger or irritability in response to minor slights and insults.
C. The impairments in personality functioning and the individual‟s personality trait expression are relatively stable across time and consistent across situations.
D. The impairments in personality functioning and the individual‟s personality trait expression are not better understood as normative for the individual‟s developmental stage or socio-cultural environment.
E. The impairments in personality functioning and the individual‟s personality trait expression are not solely due to the direct physiological effects of a substance (e.g., a drug of abuse, medication) or a general medical condition (e.g., severe head trauma).
