What Is Health Anxiety?

Health anxiety is when normal worries about your health cross into territory where they start to interfere. You check symptoms, you worry about normal bodily sensations, and reassurance from doctors doesn't stick.

The HAI-18 captures this kind of worry in 18 questions — and it separates health anxiety from general anxiety, which is useful because the two often look the same.

Scoring

Two subscales:

  • Main scale (14 items): general health anxiety (worry about illness, attention to bodily changes, fear of health threats)
  • Negative consequences (4 items): beliefs about what it would mean if you got seriously ill
Higher totals may indicate elevated health anxiety, but this is a screening tool — not a diagnosis.

Psychometrics

  • alpha = .89--.96 (main scale), .80--.89 (negative consequences)
  • Discriminates between hypochondriasis and other anxiety disorders
  • Correlates moderately with general anxiety measures but captures something distinct
> If health worries are causing you distress or affecting your daily life, talk to a doctor or mental health professional.
