Insights
Internalizing problems in preschoolers predict future chronic pain, but chronic pain does not predict internalizing problems. This suggests a unidirectional link where emotional difficulties may lead to physical symptoms in early childhood.
Area of Science:
- Child Psychology
- Developmental Pediatrics
- Behavioral Health
Background:
- Concurrent associations between chronic pain and internalizing problems are known.
- The directionality of this relationship in early childhood is not well understood.
Purpose of the Study:
- To investigate the bidirectional relationship between chronic pain and internalizing problems in preschoolers.
- To examine the persistence of chronic pain over time in this age group.
Main Methods:
- Prospective, population-based cohort study (Generation R) with 3,996 children.
- Maternal and paternal reports of child's pain and internalizing problems at ages 3 and 6 years.
- Inclusion of data on family functioning, discipline, and parental psychopathology.
Main Results:
- Internalizing problems at age 3 predicted chronic pain at age 6 (maternal OR 1.05, paternal OR 1.03).
- Chronic pain at age 3 did not predict internalizing problems at age 6.
- Prevalence of chronic pain was 2.7% at age 3 and 8.0% at age 6.
Conclusions:
- The relationship between chronic pain and internalizing problems in early childhood is largely unidirectional.
- Internalizing problems appear to increase the risk for developing chronic pain.
- Comprehensive assessment of psychiatric issues is crucial for understanding chronic pain manifestation.
Abstract:
Chronic pain and internalizing problems are characterized by concurrent associations but the directionality of this relationship in early childhood remains unclear. This prospective study aimed to investigate the bidirectional effect of chronic pain and internalizing problems and test the persistence of pain over time in a population-based sample of preschoolers. The study was embedded in Generation R, a large population-based cohort. Mothers of 3,996 children assessed their child's experienced pain and internalizing problems at 3 and 6 years. At 3 years, paternal reports were available too. Reports of family functioning, discipline practices and parental psychopathology were also collected. The prevalence of chronic pain was 2.7% (106) and 8.0% (294) at baseline and follow-up, respectively. The presence of internalizing problems at child age 3 years predicted chronic pain at 6 years, for both maternal (OR 1.05, 95% CI 1.02,1.07, p < 0.001) and paternal (OR 1.03, 95%CI 1.00, 1.06, p < 0.05) internalizing problem reports, when adjusted for potential confounding factors. In contrast, chronic pain did not increase the likelihood of internalizing problems. The temporal relationship between chronic pain and internalizing problems appears to follow a largely unidirectional trend in early childhood, with internalizing problems increasing the likelihood of concurrent physical symptoms. Current understanding of the directionality of this relationship, highlights the importance for comprehensive assessment of psychiatric problems contributing to the manifestation of chronic pain.
