Anxiety disorders represent one of the most common and debilitating forms of psychopathology in children. While empirical research, mental health funding, and mental health professionals continue to focus on the treatment rather than prevention of anxiety disorders in children, preliminary research presents an optimistic picture for preventative strategies in the future. Knowledge of the risk factors, protective factors, and treatment strategies associated with childhood anxiety disorders, in conjunction with theories regarding the methods, timing, levels, and targets of prevention, equip us well for effectively preventing childhood anxiety disorders in the future.
