The Relationship of Personality to the Presence of Rheumatoid Factor in Asymptomatic Relatives of Patients with Rheumatoid Arthritis

Abstract
Two groups of asymptomatic female relatives of patients with rheumatoid arthritis were compared psychologically by means of the Minnesota Multiphasic Personality Inventory. The results indicated a greater incidence of emotional decompensation in those relatives lacking rheumatoid factor. It is speculated that emotional disturbance in conjunction with rheumatoid factor may lead to rheumatoid disease.
