How has the COVID-19 pandemic affected family dynamics and sibling relationships? To find out, we invite parents and children from the same families to participate in a virtual study. Families who meet the criteria will complete an online parent survey in which parents will answer questions about pandemic-related changes in their family’s resources, their own stress levels, and their family’s daily routine. The survey should take about 30 minutes to complete. Afterwards, children will take part in a virtual interview during which they will answer questions about how they play with their siblings and how they feel about their siblings. The child interview should also take about 30 minutes to complete.
