Depression and Anxiety as Moderators of the Pain-Social Functioning Relationship in Youth with Sickle Cell Disease.

PURPOSE:Youth with sickle cell disease (SCD), a genetic disorder of red blood cells, may experience acute pain episodes lasting 2 to 3 days on average. While existing research has demonstrated associations between SCD pain and poor social functioning in youth with SCD, there are no data on whether symptoms of depression and anxiety modify the relationship between pain and functional outcomes in pediatric pain populations. It was hypothesized that more symptoms of depression and anxiety would exacerbate the relationship between high pain and poor social functioning in youth with SCD. PATIENTS AND METHODS:We conducted a cross-sectional study of 114 youth with SCD and their guardians assessing the youth's pain, social functioning, and symptoms of depression and anxiety. RESULTS:Analyses indicated that elevated levels of depressive symptoms were related to poorer self-reported interpersonal skills. More anxiety symptoms were related to better guardian-reported social skills and weakened the relationship between high pain frequency and poor self-reported interpersonal skills. CONCLUSION:Findings build on previous work supporting the need for multidisciplinary approaches to care for youth with SCD who experience pain, and provide rationale for future studies to investigate the direct and possible moderating effects of depression and anxiety symptoms on other functional outcomes in youth with SCD and other pediatric pain populations.
