Personality traits are enduring patterns of perceiving, relating to, and thinking about the environment and oneself, and are exhibited in a wide range of important social and personal contexts. It is only when personality traits are inflexible and maladaptive and cause either significant functional impairment or subjective distress that they constitute personality disorders. The manifestations are usually recognizable by adolescence or earlier and continue through most of adult life.
