Step-by-step explanation:
Providing open education sessions to teach parenting skills is a primary prevention strategy that can assist in preventing new episodes of child maltreatment. Primary prevention strategies are designed to prevent problems before they occur, by intervening in a broad way that targets the general population or a whole community. In this case, the open education sessions aimed at teaching parenting skills do not target individuals or families who have already experienced child maltreatment, which would be the focus of secondary or tertiary prevention strategies. Instead, they provide all interested individuals with the knowledge and tools to foster healthier parent-child relationships, thus preventing potential maltreatment from arising.
