Personality Traits in Fibromyalgia (FM): Does FM Personality Exists? A Systematic Review

Fibromyalgia (FM) is the second most common rheumatic disease with many effects on patient's quality of life. It has been described as a chronic condition characterized by widespread musculo-skeletal pain, sleep disorders and prominent fatigue. Regarding the role of personality factors in fibromyalgia, researchers have focused both on personality traits and psychopathological aspects showing inconsistent results. In particular, several studies have examined the role of alexithymia in FM patients, a trait of personality characterized by difficulty in identification, recognition and description of emotions and feelings, while others have focused on a specific type of personality, such as type D personality (distressed personality). Other studies investigated personality in FM patients referring to Cloninger's model, a psychobiological model of personality that includes both temperamental and character dimensions of personality. Analyzing scientific literature on this subject seems well suited to provide a critical review of the latest studies and their results.
