Abstract
OBJECTIVE
Unintentional poisoning in the home is a risk for children. Over-the-counter medicinal products in child-resistant containers (CRC) are common causes of pediatric poisoning. The current study examined children's abilities to open three types of CRC mechanisms (twist, flip, and push) and corresponding control containers, comparing their ability to do so spontaneously and after explicit modeling. The study also examined if inhibitory control (IC) was associated with children's overall score for spontaneous openings.
METHOD
Children 5-8 years old were randomly assigned to one of three mechanism conditions (between-participants factor): twist, flip, and push, with each child experiencing both a risk and a control container (within-participants factor) having that mechanism. Children were first left alone with a container (measures: engagement with container, spontaneous opening) for up to 2 min and subsequently observed an adult explicitly model opening the container before the child was asked to do so (measure: opening after modeling).
RESULTS
Children were more engaged with and likely to spontaneously open control containers than CRCs, though some (4%-10%) also opened CRCs. After modeling, significantly more children opened each of the three types of CRCs, with nearly all children opening the push mechanism CRC. IC positively predicted children being more engaged with and spontaneously opening more containers.
CONCLUSIONS
Implications for improving pediatric poison prevention are discussed.
