Insights

Parental factors significantly influence pediatric mild traumatic brain injury (mTBI) recovery. This study identified distinct post-injury symptom trajectories and linked them to family functioning, guiding targeted interventions for better child outcomes.

Area of Science:

  • Pediatric neurology and rehabilitation
  • Child psychology and development
  • Family systems and intervention research

Background:

  • Family environment is crucial for pediatric traumatic brain injury (TBI) recovery, yet parental and family factors in mild TBI (mTBI) are understudied.
  • Conventional analyses of postconcussive symptoms (PCS) assume homogeneity in pediatric mTBI, overlooking diverse recovery patterns.
  • Distinct symptom trajectories over time are likely in children following mTBI.

Purpose of the Study:

  • To identify distinct trajectories of postconcussive symptoms (PCS) in children and adolescents after mild traumatic brain injury (mTBI).
  • To examine the association between these PCS trajectories and parental/family functioning.
  • To inform the development of family-based interventions for pediatric mTBI recovery.

Main Methods:

  • Group-based multitrajectory modeling was employed to identify latent clusters of children with similar PCS patterns.
  • 506 children (8-16 years) with mTBI were recruited from emergency departments; data collected on injury, PCS, and family functioning.
  • Validated measures assessed family functioning, parental adjustment, social support, and parental responses to symptoms over 6 months.

Main Results:

  • Six distinct PCS trajectories were identified, including 'low acute/resolved', 'low acute/declining', 'moderate acute/elevated cognitive', 'moderate acute/declining', 'high acute/declining', and 'high acute/persisting'.
  • Parental adjustment, protectiveness, and perceived social support independently predicted trajectory membership.
  • These parental factors remained significant predictors after controlling for demographic and injury characteristics.

Conclusions:

  • Children exhibit diverse PCS trajectories following mTBI, challenging the assumption of a homogenous recovery.
  • Specific aspects of parental and family functioning are critical predictors of these symptom trajectories.
  • Findings support the development of family-centered treatments to target children at risk for prolonged recovery after pediatric mTBI.
