This paper outlines a way for thinking about continuity and change in childhood anxiety symptoms. Considerations for a model of continuity and change in anxious emotion are discussed first. Then, a perspective which may resolve inconsistencies across studies on the stability of childhood anxiety problems overtime is presented. The perspective views dysregulation of the anxiety response system and distress/negative affect as the core primary and necessary features of maladaptive anxious emotion and views the disorder-specific symptoms (generalized anxiety disorder, social phobia, separation anxiety, panic disorder, and simple phobia) as secondary characteristics of maladaptive anxious emotion. The perspective emphasizes ordered complexity in the developmental expression of anxious emotion, and delineates expectations for continuity and change in the features of anxious emotion by describing major normative trajectories across childhood and positing multiple sub-trajectories.
