Alteration of memory in the reduction of children's distress during repeated aversive medical procedures.

The present study sought to reduce children's distress during aversive medical procedures using a brief, cost-effective intervention aimed at reframing memory. Fifty children diagnosed with leukemia (25 treatment, 25 attention control, aged 3-18) were observed as they underwent 3 consecutive lumbar punctures (LPs; baseline, postintervention, and follow-up). Self-report, physiological, and observable distress measures were collected before and after each LP. At posttreatment, children in the intervention group showed reductions in anticipatory physiological and self-report ratings relative to the control group. At follow-up, these effects generalized to reductions in procedural distress. These results suggest that (a) a simple memory-based intervention is efficacious at reducing children's distress and (b) benefits from this intervention are maintained over 1 week even without continued intervention.
