Psychological aspects and hospitalization for pain crises in youth with sickle-cell disease.

Sickle-cell disease is a genetic disorder characterized by severe pain episodes or "vaso-occlusive crises" that may require hospitalization. This study examined the associations among emotion regulation, somatization, positive and negative affect, and hospitalizations for pain crises in youth with sickle-cell disease. Multivariate analyses indicated that emotional suppression and somatization were significantly associated with more frequent hospitalizations for pain crises in the previous year after controlling for sickle-cell disease type and pain. These results suggest that efforts to reduce emotional suppression and somatization may assist in decreasing the frequency of hospitalizations for pain crises among youth with sickle-cell disease.
