Earlier studies have shown that SLE significantly impacts QOL in adults. At present, there is no disease-specific instrument for measuring HRQOL in children with SLE. In response to these concerns, we developed the "Simple Measure of Impact of Lupus Erythematosus in Youngsters© (SMILEY©). Establishing the validity and reliability of SMILEY©, examining child-parent agreement and identifying factors associated with poorer HRQOL will enable us to measure the impact of SLE in children, and formulate appropriate interventions for this sensitive population. We plan the following specific aims:
