Insights
Family functioning, including intimacy, conflict, and parenting, remained stable 7-10 years after pediatric traumatic brain injury (TBI). Pre-injury assessments may identify at-risk families for better TBI recovery outcomes.
Area of Science:
- Pediatric neurosurgery
- Family psychology
- Child neurology
Background:
- Pediatric traumatic brain injury (TBI) significantly impacts children and their families.
- Understanding long-term family functioning post-TBI is crucial for recovery.
- Existing research often lacks longitudinal data on family dynamics after pediatric TBI.
Purpose of the Study:
- To identify distinct family functioning trajectories in the 7-10 years following pediatric TBI.
- To explore predictors associated with these family functioning trajectories.
- To assess changes in family intimacy, conflict, and parenting styles over time post-TBI.
Main Methods:
- Prospective recruitment of 137 families with children aged 1-12 years who experienced TBI.
- Utilized the Intimacy, Conflict and Parenting Style: Family Functioning Scale at multiple time points (pre-injury to 7-10 years post-injury).
- Employed group-based trajectory modeling to identify latent functioning profiles and explored associations with child, family, and injury characteristics.
Main Results:
- Identified four distinct intimacy profiles, four conflict profiles, and three parenting style profiles.
- Family functioning levels remained largely stable from pre-injury across the 7-10 year follow-up period.
- No reliable associations were found between trajectory membership and child, family, or injury characteristics.
Conclusions:
- Family functioning (intimacy, conflict, parenting) generally does not change significantly after a child's TBI.
- Pre-injury family functioning assessments are vital for identifying children at risk for poorer TBI recovery outcomes.
- These stable family dynamics highlight the importance of early intervention and support tailored to pre-existing family characteristics.
Objective:
To investigate the presence of specific family functioning trajectories in the 7-10 years after pediatric traumatic brain injury (TBI) and explore predictors associated with these trajectories.
Methods:
One hundred and thirty-seven families of children aged 1-12 years who experienced traumatic brain injury were prospectively recruited from a single site, statewide tertiary pediatric hospital. Assessments of family functioning were undertaken using the Intimacy, Conflict and Parenting Style: Family Functioning Scale at preinjury, 6-months, 12-months, 30-months, and 7-10 years. Group-based trajectory modeling was used to identify latent trajectories of functioning. Associations with child, family, and injury characteristics were explored.
Results:
We identified four distinct family intimacy profiles, four conflict profiles, and three parenting style profiles. Profiles were characterized by their level of functioning, which remained mostly stable from pre-injury levels across the 7-10 years post-injury. Trajectory membership was not reliably related to characteristics of the child, family, or injury.
Conclusions:
These findings suggest that, while families operate at different levels of intimacy, conflict, and parenting flexibility, these do not change after a child's TBI. Given the established role of family functioning in shaping recovery outcomes, assessments of pre-injury family functioning may enable identification of families with children at risk for poorer outcomes post-TBI.
