Fagerström Test for Nicotine Dependence
Fagerström Test for Nicotine Dependence - Smoking Severity Assessment · Also known as: FTND, Fagerstrom Test
The Fagerström Test for Nicotine Dependence (FTND) is a brief, validated self-report instrument originally developed by Fagerstrom in 1978 and revised by Heatherton and colleagues in 1991 to quantify the severity of nicotine dependence in cigarette smokers. The FTND comprises six items assessing morning cigarette use, daily cigarette consumption, and the subjective difficulty of abstaining from smoking. It is the most widely used measure of nicotine dependence in smoking cessation research and clinical practice.

When to use it
FTND is indicated for quantifying nicotine dependence severity in all smokers considering or planning smoking cessation. Use at baseline to establish dependence level and guide treatment intensity decisions, during quit attempts to monitor symptom development, or in research examining predictors of cessation success. Appropriate for primary care, tobacco cessation clinics, and smoking cessation research.
Strengths & limitations
- Brief (6 items, 2-3 minutes) enabling routine administration in busy clinical settings
- Strong psychometric properties with excellent reliability and validity for predicting cessation difficulty
- Directly predicts outcomes: higher scores predict lower quit rates without pharmacotherapy and better response to pharmacological treatment
- Extensive research base demonstrating utility in diverse populations and international settings
- Does not assess motivation to quit or readiness for change, which are crucial determinants of cessation success independent of dependence severity
- Limited assessment of withdrawal symptom severity or cognitive dependence; measures primarily behavioral dependence
- May not fully capture dependence in infrequent or non-daily smokers whose patterns don't fit traditional daily-cigarette models
Frequently asked
Does the FTND assess psychological dependence or only physical dependence?
FTND primarily measures behavioral and physical dependence patterns (cigarettes per day, morning use, difficulty refraining). It does not specifically assess psychological dependence such as anxiety relief, habit, or emotional regulation functions of smoking. Comprehensive cessation assessment should include evaluation of smoking's psychological functions alongside FTND physical dependence scoring.
Should a low FTND score mean the person will quit easily?
Not necessarily. FTND measures nicotine dependence severity but not motivation, prior quit attempts, psychiatric comorbidities, or environmental triggers. A low-dependence smoker highly motivated to quit may succeed without pharmacotherapy, whereas a low-dependence smoker with depression or high environmental stress may struggle despite low dependence. FTND should be used alongside assessment of motivation and comorbidities.
How does FTND compare to biochemical measures like cotinine or carbon monoxide?
FTND measures subjective and behavioral dependence patterns, not actual nicotine exposure. Biochemical measures (cotinine, carbon monoxide) objectively verify smoking exposure. FTND and biochemical measures complement each other: FTND guides clinical decision-making, while biochemical verification confirms abstinence during treatment. Some smokers report high FTND scores but show lower biomarkers (underreporting consumption); others show discrepant patterns indicating need for motivational assessment.
