To investigate the reproducibility and validity of self-administered joint counts (JC), measuring tenderness, swelling and the combination of both, in a longitudinal study.
At the outpatient department a form self-administered by patients (SAI-form), was used to measure joint involvement. Concurrent joint examinations were performed by an assessor. The JC and scores for groups of joints by assessors were correlated with those by patients. As a retest the form was completed again by the patients within 10 days. Correlations between the JC measured by the test and retest were computed to investigate reproducibility.
Correlations between test and retest were high (> 0.7). Correlations between JC and groups of joints measured by the assessors and by the patients were moderate (0.06). Correlations with other disease activity variables did not differ between assessors' and patients' joint examination scores.
The patient-administered joint examination was reproducible; however, correlation with the assessors' joint examination was moderate. The value of the self-administered joint count needs further examination and cannot yet replace the assessor's joint examination.
在一项纵向研究中，调查患者自行进行的关节计数（JC）在测量压痛、肿胀以及两者综合情况方面的可重复性和有效性。
在门诊部，使用患者自行填写的表格（SAI表格）来测量关节受累情况。由一名评估者同时进行关节检查。评估者对关节组的JC和评分与患者的进行相关性分析。作为重测，患者在10天内再次填写该表格。计算测试和重测所测量的JC之间的相关性，以研究可重复性。
测试和重测之间的相关性很高（>0.7）。评估者和患者所测量的JC与关节组之间的相关性中等（0.06）。评估者和患者的关节检查评分与其他疾病活动变量之间的相关性无差异。
患者自行进行的关节检查具有可重复性；然而，与评估者的关节检查相关性中等。自行进行的关节计数的价值需要进一步研究，目前尚不能取代评估者的关节检查。
