Fear of COVID-19 Infection Scale
Fear of COVID-19 Infection Scale (FCV-19S) · Also known as: FCV-19S, Fear of COVID-19 Scale
The Fear of COVID-19 Scale (FCV-19S) is a 7-item, self-report instrument assessing fear of COVID-19 infection across cognitive, emotional, and physiological domains. Developed by Ahorsu and colleagues in 2020, it measures threat perception, anxiety symptoms triggered by disease-related triggers, and avoidance behaviors. The FCV-19S has been translated into over 40 languages and validated across diverse populations, making it the most widely used pandemic-specific fear measure globally.

When to use it
The FCV-19S is suitable for rapid screening in clinical, community, and research settings during active pandemic phases. Use in occupational health to identify healthcare workers or essential workers at elevated fear risk. Appropriate for measuring fear trajectories longitudinally across pandemic waves, intervention trials, or post-vaccination periods. Sensitive to detecting rapid changes in population fear related to epidemiological events (variant emergence, case surges). Especially valuable in multilingual settings due to extensive translation validation.
Strengths & limitations
- Parsimonious 7-item format balances comprehensive coverage with practical brevity, enabling large-scale epidemiological surveillance without respondent burden.
- Exceptional international validation—translated, back-translated, and validated in 40+ languages and diverse cultural contexts (Iran, Italy, China, Spain, United Kingdom, United States, Hong Kong, Turkey, Brazil, etc.), supporting cross-national comparisons.
- Strong psychometric properties with high internal consistency (Cronbach α = 0.82–0.88 across samples), excellent test-retest reliability (ICC = 0.84–0.90), and robust convergent validity with GAD-7 (r = 0.62–0.71) and PCL-5 (r = 0.51–0.68).
- Sensitive to epidemiological changes; mean FCV-19S scores show predictable increases during variant surges and decreases during low-transmission periods, validating construct responsiveness.
- Lacks dimensional subscales; unable to distinguish between cognitive threat appraisal, emotional fear responses, and behavioral avoidance without post-hoc factor analysis.
- Moderate ceiling effects in vaccinated or post-pandemic samples (15–20% score at minimum), limiting discrimination in low-fear populations.
- Pandemic-specific wording assumes active threat; requires rewording for historical assessment or novel pathogen contexts, limiting longitudinal applicability.
- Does not assess health-protective behaviors or compliance; correlations with behavior moderate (r = 0.40–0.55), suggesting fear alone is insufficient predictor of precautionary action.
Frequently asked
How does FCV-19S relate to clinically significant anxiety or phobia?
FCV-19S ≥28 correlates with clinical anxiety and phobic symptoms, but diagnosis requires clinical interview assessing functional impairment and DSM-5 criteria. The scale identifies risk; clinical judgment determines disorder status. Approximately 10–15% of community samples score ≥28 during high-transmission periods.
Is the FCV-19S valid for measuring fear of new variants or endemic COVID-19?
Yes. The scale is variant-agnostic and responds to perceived threat regardless of source. For endemic phase or new pathogens, consider rewording 'COVID-19' to the specific threat. Validation studies confirm responsiveness to variant-driven surges and sub-variant emergence.
What is the relationship between FCV-19S and vaccination status?
Vaccinated individuals typically score 3–5 points lower than unvaccinated peers in the same epidemiological period (mean difference d = 0.35–0.55). However, vaccine-hesitant individuals may score higher due to fear of vaccination itself. Use FCV-19S pre- and post-vaccination to measure fear reduction as an outcome.
Are there clinical cutoffs for diagnosing 'pandemic phobia' or 'COVID-19 specific phobia'?
No validated diagnostic cutoff exists in DSM-5. FCV-19S ≥28 indicates elevated risk for specific phobia and warrants clinical interview, but fear alone does not constitute diagnosis. Diagnosis requires irrational fear, avoidance causing functional impairment, and 6+ months' duration. Use FCV-19S as screening, not diagnosis.
