    What are the components of the anxiety response?

    The four components of the anxiety response are the bodily reactions, thoughts, feelings and behaviors through which anxiety shows itself. Cognitive therapy treats them as linked, so a change in one moves the others;[1] earlier, Peter Lang divided fear into verbal (cognitive), overt motor and somatic response systems.[2]

    What research says

    Schematic. Lines show mutual influence, not its strength; how many components there are depends on the model.

    Schematic. The four boxes at the top are the four components of anxiety: body, thoughts, feelings and behavior, each linked to every other, so a change in one moves the rest; the outer frame is the situation and environment they sit in. Four cards below cover Lang’s three response systems, the ways the components fail to line up, a typical loop in panic, and the fact that change can start anywhere. Select a part for details.

    Key points

    • Lang saw that reported fear often failed to match avoidance or bodily changes, so he proposed three response systems, each adding to fear’s intensity and each a target for therapy.[2]
    • They diverge: intense reported fear can come with a normal heart rate; beta-blockers may calm the heart but not felt anxiety; in therapy, behavior and physiology often change before reported fear.[2]
    • Clark’s model of panic: harmless sensations, such as a racing heart, misread as catastrophe (“a heart attack”) spark fear and panic. A seven-study meta-analysis found this misreading more common in panic disorder.[3]
    • Behavior feeds back: avoidance and safety behaviors, such as keeping a phone at hand or planning an exit, bring relief now but leave fears untested, so anxiety and reliance on them grow.[4]

    An example

    Jay is waiting to hear about a job interview when an unknown number calls. His heart jumps, he thinks “What if it’s a no?”, dread builds, and he lets it ring. Then he worries he has missed the news, and his heart races again. Body, thoughts, feelings and behavior keep feeding one another.

    Misreadings and limits

    The four components are a teaching division, not four kinds of anxiety, and models split them differently. Reported fear overlaps only partly with behavioral and physiological measures, about 27–28% of shared variance at the most optimistic, so a racing heart does not always mean intense fear, or vice versa.[2]
