Personality Disorders


Personality disorders are a wide range of mental health conditions that involve lasting and disruptive patterns in thinking, mood, behaviours, and relationships. These disorders may distress the person or cause significant impairment in their lives, such as their work and personal relationships.


Personality disorders are generally categorized into three clusters: 

Cluster A personality disorders: 

  • A Cluster A Personality Disorder is marked by eccentric and unusual thinking and behaviours. This may include Paranoid Personality Disorder, Schizoid Personality Disorder, or Schizotypal Personality Disorder. 

Cluster B personality disorders:

  • A Cluster B Personality Disorder can be observed in people displaying dramatic or erratic behaviour. People suffering from a Cluster B Personality Disorder may experience intense emotions, can be emotionally unstable and may partake in impulsive behaviours. This may include Antisocial Personality Disorder (ASPD), Borderline Personality Disorder, (BPD), Histrionic Personality Disorder and Narcissistic Personality Disorder

Cluster C personality disorders:

  • A Cluster C Personality Disorder may involve intense anxiety and fear. This may include disorders such as Avoidant Personality Disorder, Dependent Personality Disorder and Obsessive-Compulsive Personality Disorder

Psychology interventions can help to manage personality disorders by identifying and modifying distressing emotions and changing maladaptive thinking patterns, decreasing unwanted social behaviour, and working on personality traits that are impairing happiness and overall quality of life.
