Psychological aspects of rheumatoid arthritis

This study had 3 aims: to determine whether rheumatoid arthritics had certain personality traits; to examine the relationship between psychological factors and the presence of rheumatoid factor in blood serum; and to explore the prognostic significance of psychological factors in the management of rheumatoid arthritis. Within a few days of discharge, 129 in-patient rheumatoid arthritics were clinically and psychologically assessed and allocated at random to 1 of 3 forms of follow-up care. The psychological assessment included measures of personality, non-psychotic psychiatric disturbance, and attitudes and beliefs. A year later all patients were reassessed. It was found that rheumatoid arthritics were more neurotic in personality, more likely to give socially desirable responses, and more prone to psychiatric disturbance, than the general population. Seropositive patients were less susceptible to psychiatric disturbance than seronegative patients. None of the psychological variables predicted disease activity, but those patients who rated themselves as 'slow, dependent, and weak' lost more time off work in the subsequent year.
