Prenatal PAH and Maternal Distress Exposure Linked to Childhood Irritability Trajectories

Data Sheet 1_Combined prenatal exposure to airborne polycyclic aromatic hydrocarbons and maternal distress is associated with childhood irritability, authored by Mariah DeSerisy and last updated on 2026-06-02. The dataset contains results from a longitudinal study of 511 children, with 394 having complete exposure and outcome data, examining the interactive effects of prenatal PAH exposure and maternal psychological distress on irritability symptoms at ages 7, 9, and 11. The irritability composite score was constructed from the Children's Behavior Checklist and Conner's Parent Report Scale.

Use Cases

• Modeling latent growth curves based on longitudinal irritability scores at ages 7, 9, and 11.
• Analyzing interaction effects between prenatal PAH exposure and maternal psychological distress on child outcomes.
• Validating a novel psychometric composite for childhood irritability using item-level responses from established parent-report scales.

Strengths

• Dataset is based on a sample of 511 children with psychometric evaluation.
• Exposure data includes objective personal air monitoring for PAHs and a validated instrument (Psychiatric Epidemiology Research Instrument) for maternal distress.
• Longitudinal outcome data was collected at three distinct developmental timepoints (ages 7, 9, 11).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is relatively small at 2.2 MB, potentially limiting statistical power for complex analyses.

Collection Method

Prenatal PAH measured via personal air monitoring; maternal distress measured via Psychiatric Epidemiology Research Instrument–Demoralization; child irritability measured via composite of Children's Behavior Checklist and Conner's Parent Report Scale.

Time Range

Data collection occurred during mothers' third trimester and when children were ages 7, 9, and 11.
