The subjective symptoms of FM may be influenced by personal perceptions, and environmental and psychosocial factors. Therefore SES may influence symptom expression and severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods.<\/jats:title>\n                    <jats:p>Data for this cross-sectional analysis were obtained from a real-life prospective cohort of 246 patients with FM categorized according to level of education: high school graduates or less (Group 1; n = 99), college graduates (Group 2; n = 84), and university graduates (Group 3; n = 63).
