Commentary 2: Sibling Power Dynamics: The Role of Family and Sociocultural Context.

The balance of power and control is an understudied, yet important, aspect of the sibling relationship that is theorized to shift over the course of development from early childhood to young adulthood. The investigations in this issue offer support for this overall progression, but extend prior research by providing a nuanced understanding of sibling power dynamics using different methodologies, analytic approaches, and study designs. Grounded within an ecological framework, directions for future research are offered to expand our understanding of sibling power dynamics in diverse family and sociocultural contexts.
