Summary

This study tested the effects of emotion regulation strategies (reappraisal, reassurance, and empathy) on pain responses in children with cancer. Children with cancer were randomly assigned to one emotion regulation strategy during an experimental pain task (the cold pressor task \[CPT\]). During the CPT, children rated their pain and provided saliva samples immediately before, after, and then 15 minutes after the CPT. This study examined the influence of emotion regulation on self-reported pain and physiological activity assessed through saliva samples.

Detailed description

More than 12,000 children are diagnosed with cancer in the United States each year and the majority of these children will experience pain throughout their illness. Children with cancer are required to undergo repeated invasive medical procedures, including bone marrow aspirations (BMA) and lumbar punctures (LP), which have been described by children as the most distressing and painful aspect of their illness. The experience and memory of procedural pain can have a lasting effect and impact distress in future procedures; children learn to anticipate pain and show increased distress and decreased cooperation at subsequent procedures. Moreover, childhood medical distress has also been linked to adults' reports of pain and fear around medical events and even avoidance of future health care. Early painful procedures have also been associated with behavioral changes to medical events later in life, a finding that is supported by recent physiological evidence indicating that activation of the pain processing system in the brain can change neuropathways, which leads to increased sensitivity to later stimulation of pain systems. Therefore, it is vital to develop strategies to minimize the pain and distress that children undergo through cancer treatment and understanding the impact of children's memory on pain is a crucial step in this process. To address this important need, this study involved identifying the strategies that children use to cope with distress that promote positive memories of medical events, examining how these strategies impact their immediate physiology (via salivary biomarkers) and self-reported pain, and understanding how these coping strategies change children's distress over time during future medical procedures. Specifically, certain coping strategies change the way that children interpret stressful medical procedures, which affects the emotional response to future procedures. These objectives were accomplished by the following specific aims: Aim 1: Identify emotion-regulation (i.e., coping) strategies that promote more positive memories of distressing medical procedures in children with cancer. Aim 2: Assess the impact of emotion-regulation strategies on children's distress response to painful procedures over time. This project will provide specific means for impacting children's pain and distress during medical procedures. Specifically, because the emotion regulation strategies described in this protocol are modifiable and teachable, they provide direct implications for clinical practice in pain management by identifying strategies that can decrease children's pain and anxiety throughout their course of cancer treatment.

Interventions

Type	Name	Description
BEHAVIORAL	Reapprasial Condition	Children in this condition will be instructed to think about how the procedure will help them become adjusted to cold weather.
BEHAVIORAL	Reassurance Condition	Children will be reassured by the experimenter .
BEHAVIORAL	Distraction Condition	Children in this condition will be instructed to focus their attention on a picture on a computer screen rather than on the pain.
