While characteristics such as living in poverty, experiencing significant daily stressors, and increased exposure to traumatic events are all identified as major contributors to anxiety disorders, additional sociocultural influences such as gender and discrimination have also received a great deal of attention.

Why do women have anxiety disorders?

One potential explanation for this discrepancy is the influence of social pressures on women. Women are more susceptible to experience traumatic experiences throughout their life, which may contribute to anxious appraisals of future events. Furthermore, women are more likely to use emotion-focused coping, which is less effective in reducing distress than problem-focused coping (McLean & Anderson, 2009). These factors may increase levels of stress hormones (e.g., cortisol) within women that leave them susceptible to develop symptoms of anxiety. Therefore, it appears a combination of genetic, environmental, and social factors may explain why women tend to be diagnosed with anxiety disorders more often than men.

Why is physiological arousal important for anxiety?

Sensitivity to physiological arousal not only contributes to anxiety disorders in general, but also for panic disorder where individuals experience various physiological sensations and misinterpret them as catastrophic. One explanation for this theory is that individuals with panic disorder are actually more susceptible to more frequent and intensive physiological symptoms than the general public (Nillni, Rohan, & Zvolensky, 2012). Others argue that these individuals have had more trauma-related experiences in the past, and therefore, are quick to misevaluate their physical symptoms as a potential threat. This misevaluation of symptoms as impending disaster likely maintain symptoms as the cognitive misinterpretations to physiological arousal creates a negative feedback loop, leading to more physiological changes.

How does modeling help with social phobias?

Modeling is another behavioral explanation of the development of specific and social phobias. In modeling, an individual acquires a far through observation and imitation (Bandura & Rosenthal, 1966). For example, when a young child observes their parent display irrational fears of an animal, the child may then begin to display similar behaviors. Similarly, observing another individual being ridiculed in a social setting may increase the chances of the development of social anxiety, as the individual may become fearful that they would experience a similar situation in the future. It is speculated that the maintenance of these phobias is due to the avoidance of the feared item or social setting, thus preventing the individual from learning that the item/social situation is not something that should be feared.

What is the brain responsible for a fear response?

Researchers have identified several brain structures and pathways that are likely responsible for anxiety responses. Among those structures is the amygdala, the area of the brain that is responsible for storing memories related to emotional events (Gorman, Kent, Sullivan, & Coplan, 2000). When presented with a fearful situation, the amygdala initiates a reaction in efforts to prepare the body for a response. First, the amygdala triggers the hypothalamic-pituitary-adrenal (HPA) axis to prepare for immediate action— either to fight or flight. The second pathway is activated by the feared stimulus itself, by sending a sensory signal to the hippocampus and prefrontal cortex, to determine if the threat is real or imagined. If it is determined that no threat is present, the amygdala sends a calming response to the HPA axis, thus reducing the level of fear. If there is a threat present, the amygdala is activated, producing a fear response.

How does fear of one thing become a phobia?

While modeling and classical conditioning largely explain the development of phobias, there is some speculation that the accumulation of a large number of these learned fears will develop into GAD. Through stimulus generalization, or the tendency for the conditioned stimulus to evoke similar responses to other conditions, a fear of one item (such as the dog) may become generalized to other items (such as all animals). As these fears begin to grow, a more generalized anxiety may present, as opposed to a specific phobia.

What is cognitive perspective in anxiety?

Maladaptive assumptions are routinely observed in individuals with anxiety disorders, as they often interpret events as dangerous and overreact to potentially stressful events, which contributes to a heightened overall anxiety level . These negative appraisals, in combination with a biological predisposition to anxiety likely contribute to the development of anxiety symptoms (Gallagher et al., 2013).
