Multimodal Intervention and Child Passenger Safety Guideline Adherence in Young Children

Is motivational interviewing (MI) with tailored mobile health (mHealth) associated with increased child passenger safety guideline adherence?In this sequential, multiple-assignment, randomized clinical trial of 474 caregivers of children aged 6 months to younger than 11 years, guideline adherence was 13.1 percentage points higher for basic intervention than for enhanced usual care at 6 months and 39.2 percentage points higher at 12 months among those who were guideline adherent at 6 months. In phase 2, an additional remote MI session plus additional text messages for intervention participants who were not adherent had no effect.This trial found that the basic intervention changed child passenger safety behaviors by 6 months and was associated with maintenance of guideline adherence to 12 months, suggesting that this intervention may protect against a leading cause of death among children.
