This study explores how intolerance of uncertainty (IU) and anxiety may explain extreme demand avoidance (PDA) in children and adolescents. Researchers from the NHS and Newcastle University examined how these factors contribute to demand-avoidant behaviours. The findings suggest that IU-a difficulty in coping with unpredictability-may be a key factor driving PDA behaviours in autistic children. This research builds on previous autism studies and has important clinical implications. Understanding the link between IU, anxiety, and demand avoidance could help improve assessment and management strategies for children with a PDA profile.
