Every person has their own personality. A typical pattern of how they think, feel, handle stress and behave in relationships. These patterns develop over the course of a lifetime, shaped by predisposition, early attachment experiences, formative events and the environment.
Personality traits are often described in psychology on a "spectrum" or scale. The well-known Big Five, for example, encompass openness, conscientiousness, extraversion, agreeableness and emotional stability. Every person sits somewhere between two opposing poles on each of these dimensions. However, when certain patterns become very pronounced, rigid and distressing over a long period of time β either for the person themselves or for those around them β professionals speak of a personality disorder. These include (according to ICD-10):
Paranoid, schizoid and schizotypal personality disorder
Antisocial personality disorder
Borderline personality disorder
Histrionic personality disorder
Narcissistic personality disorder
Avoidant personality disorder
Dependent personality disorder
Obsessive-compulsive personality disorder
The latest classification of diseases (ICD-11), which has not yet been universally adopted, no longer understands personality disorders as fixed categories but as varying degrees along different personality dimensions.
Personality Traits and Relationships
Personality traits become especially visible in relationships: closeness and autonomy must be balanced, conflicts endured, vulnerability shown, trust risked. Someone who reacts emotionally, for instance, can quickly be overwhelmed by feelings in a conflict. Someone whose personality inclines toward withdrawal tends to distance themselves rather than work through problems. Someone who feels insecure may mask it with a need for control. Empathetic people can easily overlook their own inner limits β and then become dissatisfied.
Such patterns can place lasting strain on a relationship. The person affected often suffers from inner conflicts, intense emotions or relationship anxieties. Their partner, in turn, may feel confused, exhausted or helpless because typical conflict strategies don't work. What helps in such cases: knowledge, self-reflection, clear communication, clear boundaries and often professional support as well. Personality patterns cannot be therapied away, but one can learn to handle them better. In this way, even deeply ingrained patterns can change.
