Psychosocial predictors of children's postoperative pain.

The purpose of this study was to investigate the influence of psychosocial variables in the prediction of children's pain intensity following surgery. Forty-two children, ages 7 to 17 years (M = 12.26, SD = 3.06), completed an interview 1 week prior to surgery assessing anticipatory distress related to their forthcoming surgery and history of coping strategy use. Following surgery, children reported the intensity of their pain using visual analog scales. Findings demonstrated that the majority of children experienced moderate to severe postoperative pain. Hierarchical multiple regression analyses revealed that psychosocial variables added to the prediction of children's postoperative pain after controlling for the influence of surgery-related and demographic variables. These findings lend initial support for the inclusion of psychosocial assessment measures (e.g., anticipatory surgery distress) in the preoperative assessment of pediatric patients who may be at risk for excessive postsurgical pain.
