The original study explored why some children strongly resist demands; a behaviour linked to Pathological Demand Avoidance (PDA). Researchers looked at how intolerance of uncertainty (IU) and anxiety might explain this behaviour. A year after initial publication, the journal published comments and responses alongside an editorial which discusses the issues brought up by the original paper.
