Individual Differences in the Relationship Between Pain Fear, Avoidance, and Pain Severity in a Chronic Abdominal Pain Sample and the Moderating Effect of Child Age.

The present study extends the fear-avoidance model by highlighting the importance of identifying potential individual differences when examining pain fear, avoidance, and pain severity. Furthermore, the current study suggests that child development should be considered in the model. However, future randomized control designs are necessary to explore the causal relationships between pain fear and avoidance on pain severity and potential developmental differences.
