Evidence in support of claims for the existence of a special relationship between @entity1314 and @entity309 is conflicting. In this study four groups-one of @entity1 with early @entity309 , one of @entity1 with chronic @entity309 , one of @entity6004 @entity1 , and a normal control group-were compared by means of the Maudsley Personality Inventory (M.P.I.) and a @entity6004 trait in childhood (N.T.C.) score. Both @entity625 groups had a lower M.P.I. @entity663 score than the normal control group, with greater significance in the @entity625 group. The @entity6004 group had a significantly higher @entity663 score than the other three groups. Both @entity625 groups had a lower extraversion score than normal controls, again with greater significance in the @entity625 group. The @entity6004 group scored significantly less than normal controls on the extraversion scale and intermediately between the early and @entity625 groups. There was no significant difference between the @entity625 groups and the normal control group in the N.T.C. score, but it was significantly increased in the @entity6004 group.These findings suggest that @entity1 with @entity309 differ significantly in @entity1314 from normal and from @entity6004 @entity1 , that the differences are accentuated with chronicity in the rheumatoid process, and that the differences develop as a result of the @entity625 .
