Diversity of adverse childhood experiences among adolescent mothers and the intergenerational transmission of risk to children's behavior problems.

Rationale: It is important to investigate the diversity and variability among adverse childhood experiences (ACEs) in young mothers because they are likely to experience considerable adverse exposures during childhood as well as challenging environments following childbirth.

Objective: The current study used latent class analysis with a diverse sample of young mothers to identify subgroups of mothers based on their adverse childhood experiences (ACEs). Subsequent analyses were conducted to examine class specific differences in maternal mental health postpartum and their children's socio-emotional functioning at eight years of age.

Results: Four classes of participants were identified based on mothers' ACEs, including a high, multiple-risk class, a low-risk class, a high-risk for abuse class, and a high-risk for household dysfunction class. These classes were associated with differences in maternal and child functioning. The low-risk class showed significantly better maternal and child health and well-being than the high-risk class. However, nuanced differences were seen for mothers and their children across all classes; for example, children of mothers in the high-risk for abuse class scored significantly better on internalizing behaviors than children from the high, multiple-risk class, but not better on externalizing behaviors. Further, children of mothers in the high-risk for household dysfunction class scored better than the high, multiple-risk class on externalizing behaviors but not better on scores of internalizing behaviors.

Conclusion: Understanding the differences in how certain types of childhood adversity are associated with mothers' and their children's later health and well-being will bolster the use of only a sum score of ACEs for both how we research risk and in supporting clinicians to provide targeted care.
