What are Cluster B Personality Disorders?

In our last post, we talked about Cluster A Personality Disorders. Today, we’ll be talking about Cluster B Personality Disorders. While Cluster A is characterised by odd and unusual thinking and behaviour, Cluster B is characterised by unpredictable, striking and highly emotional thinking and behaviour (Mayoclinic, n.d.). There are four personality disorders under Cluster B: Antisocial, Borderline, Histrionic and Narcissistic Personality Disorders.


Antisocial Personality Disorder

As the name suggests, ‘antisocial’ refers to behaviours that are detrimental to society. Some symptoms of antisocial personality disorder include (Mayoclinic, 2016):

  • Compulsive lying, stealing and using fake identities to cheat others

  • Dismissing the needs or feelings of others

  • Continued violation of the rights of others

  • Impulsive behaviour

  • Recurring run-ins with the law

  • Lack of guilt for misbehaviour

Borderline Personality Disorder

Borderline refers to a ‘poor or unstable sense of self’ that contributes to negative and irresponsible behaviour (Todd, 2018). Some symptoms of borderline personality disorder include (Mayoclinic, 2016):

  • Engaging in risky and impulsive behaviours like unsafe sex, gambling or binge-eating

  • Unstable and intense relationships

  • Bipolar mood swings, often due to interpersonal stress

  • Consistent feelings of loneliness

  • Consistent anger issues

  • Suicidal or self-harming behaviours

Histrionic Personality Disorder

The word histrionic suggests “dramatic or theatrical” (WebMD,n.d.). For people with histrionic personality disorder, their self-esteem is very fragile and highly dependent on the approval of others (WebMD, n.d.). To get people to notice them, they will engage in dramatic and inappropriate behaviour to feel a distorted sense of self-worth. Some symptoms of histrionic personality disorder include (Mayoclinic, 2016):

  • Consistent, attention-seeking behaviour

  • Easily swayed by others

  • Appearing shallow and excessive concern with physical appearance

  • Extremely emotional, sexually provocative or dramatic to garner attention

  • Talks dramatically with strong opinions, but unable to support his or his points with concrete evidence

  • Perceive they are closer to people around them that they really are

Narcissistic Personality Disorder

Ever heard about Narcissus? The word ‘Narcissistic’ came from Greek folklore, which tells a story of a handsome young man named Narcissus who fell in love with his reflection after seeing it in a pool of water (WebMD, n.d.). People with narcissistic personality disorders are not just in love with themselves; they are self-absorbed and ignore the feelings or ideas of others. Some symptoms of narcissistic personality disorder include (Mayoclinic, 2016):

  • Fantasise about attractiveness, power and success

  • Exaggerating talents and achievements

  • Belief that you are above others

  • Consistent anticipation of praise and admiration from others

  • Extremely high standards towards extending advantages and favours, and frequently take advantage of others

  • Arrogance
