The association between physical function and psychological problems in children with juvenile chronic arthritis

Twenty-nine children with juvenile chronic arthritis, aged from 7 to 16 yr were studied using the Juvenile Arthritis Functional Assessment Report for Children and Parents questionnaires (JAFAR-C and JAFAR-P). The results showed that JAFAR-C and JAFAR-P were highly correlated (P < 0.001) with each other and also with a predicted JAFAR score (P < 0.05). The JAFAR score correlated with the arthritic joint count at the time of the study (P < 0.01), Steinbrocker classification (P < 0.001), pain score (P < 0.01) and stiffness score (P < 0.005). Evidence of psychological dysfunction was found in eight of the 29 children (27%). Six children (21%) scored 13 or more on the Rutter A(2) for parents and one patient scored more than nine on the Rutter B(2) for teachers. Only one child had a score on the Birleson self-rating scale that was high enough to suggest a likely diagnosis of depression. The median Lipsitt self-concept scale score was 86, that expected for a healthy population. There was no correlation between the psychological scores and any of the other functional measurements, although the numbers affected were small. There was no significant difference between type of arthritis at onset with regard to any of the scores obtained.
