Intervention Group: Parents and youth in the intervention group will receive instructions about adaptive ways of reminiscing about the in-hospital and post-surgery periods. The intervention will draw from existing narrative-based interventions that have taught parents to reminisce with their children about past negative events in more elaborative and emotion-rich ways (e.g., using more open-ended questions, to follow in on children's answers by providing new details about the event, to talk more about emotions, and to praise children's answers). We will also include elements of past pain memory reframing interventions and findings from our recent data. Specifically, parents will be taught to reminisce with their children about the in-hospital and post-surgery periods by providing more explanations for events, using less utterances about pain, fear, and medical procedures, emphasizing positive aspects of the child's surgery memory (e.g., when children used coping methods such as deep breathing, when they got a treat), and enhancing children's self-efficacy regarding their ability to cope with pain. Researchers will also provide suggestions for specific questions and remarks to make while reminiscing. Parents, youth, and researchers will engage in brief role-plays to solidify the techniques, which will be followed by researcher feedback. After this training period, parents in the intervention group will be instructed to reminisce with their children about the in-hospital and post-surgery periods using the intervention strategies.
