Anxiety and Stress-Related Disorders

Set A

Amygdala

The region of the brain responsible for coordinating and initiating responses to fear.

Anxiety Disorder

An excessive or aroused state characterised by feelings of apprehension, uncertainty and fear.

Agoraphobia

A fear or anxiety of any place where the sufferer does not feel safe or feels trapped, and is accompanied by a strong urge to escape to a safe place (e.g. home).

Attention Bias Modification (ABM)

Highly anxious individuals have attentional and interpretational biases towards threat that are known to cause anxiety. ABM is a practical way of reversing these biases and uses experimental procedures that will neutralize them.

Behavioural Inhibition

A construct used to define the characteristic in some children of seeming quiet, isolated and anxious when confronted either with social situations or with novelty.

Acute Stress Disorder

A short-term psychological and physical reaction to severe trauma. Symptoms are very similar to those of PTSD, but the duration is much shorter (3 days to 1 month after exposure).

Anxiety Sensitivity (PD)

Fears of anxiety symptoms based on beliefs that such symptoms have harmful consequences (e.g. that a rapid heart beat predicts an impending heart attack).

Anxiety Sensitivity Index (PD)

A measure, developed by Reiss, Peterson, Gursky & McNally (1986) to measure anxiety severity.
