50 A study of the development of anxiety disorders in children following TBI found that 8.5% of children developed anxiety disorders, usually PTSD, within 6 months of the TBI.
"This suggests that...both host and microbial factors are required for the development of anxiety and depression-like behaviour".
Psychologist Professor Stanley Rachman, a leading authority on the development of anxiety, suggests "fears can be acquired by three pathways: conditioning, vicarious exposures and by the transmission of information and instruction".
This study focuses on behavioral vulnerability factors that contribute to the development of anxiety.
This study provides small evidences that neuroticism contributes directly to the development of anxiety and post-traumatic stress disorder.
In 1998, Chorpita, Brown, and Barlow published a now seminal study in Behavior Therapy examining the development of anxiety in children and adolescents using Barlow's 1988 model of the development of anxiety in adults.

High glucocorticoid levels induced by stress enhance the memory of fearful events and may contribute to the development of anxiety and posttraumatic stress disorder.
Thus, our results provide further evidence that 5-HTTLPR and COMT Val158Met genotypes influence the vulnerability for the development of anxiety disorders via different mechanisms.
