Introduction to the Hooked on Nicotine Checklist (HONC)
The Hooked on Nicotine Checklist (HONC) is a brief, 10-item questionnaire specifically designed to identify the onset and strength of tobacco dependence in adolescents. Developed in 2002 by Dr. Joseph DiFranza and his colleagues at the University of Massachusetts Medical School, the HONC is grounded in the autonomy theory of tobacco dependence. This theory posits that dependence begins when an individual loses full autonomy over their tobacco use, a milestone that can occur even after minimal consumption. With over 500 citations, the HONC has become an indispensable tool in addiction medicine and public health for its unique ability to detect the earliest signs of nicotine dependence in young smokers.
This article offers a comprehensive overview of the HONC’s features, its powerful scoring methodology, and its applications for researchers and clinicians working to combat adolescent smoking.
Key Features of the Hooked on Nicotine Checklist (HONC)
Purpose and Use of the Hooked on Nicotine Checklist (HONC)
The HONC primarily determines when an adolescent has completely lost control over their tobacco use. Unlike consumption-based measures like the Fagerström Test for Nicotine Dependence (FTND), which assess heavy, established smokers more effectively, the HONC is exceptionally sensitive to early dependence. It captures key indicators like impaired control, cravings, and withdrawal symptoms. These signals indicate a loss of autonomy, which makes the HONC a critical tool for early intervention.
Target Population of the Hooked on Nicotine Checklist (HONC)
Researchers originally developed and validated the HONC for adolescents (ages 12-18). Although professionals have also adapted an adult version, the scale primarily serves young populations.
Structure of the Hooked on Nicotine Checklist (HONC)
The HONC consists of 10 simple Yes/No questions that assess the core symptoms of nicotine dependence. These items cover key areas including:
- Impaired control over the amount or duration of nicotine use.
- Perceived addiction.
- Craving or needing tobacco.
- Difficulty controlling the behavior.
- Nicotine withdrawal symptoms.
Scoring Method
The HONC’s scoring system is both simple and powerful, based on the autonomy theory of dependence.
- Scoring: The scale uses binary scoring, where each “Yes” response is awarded 1 point and each “No” response receives 0 points.
- Total Score: The total score is the sum of all “Yes” responses, ranging from 0 to 10. Higher scores indicate a greater loss of autonomy and a higher degree of nicotine dependence.
- Cut-off Score: The critical cut-off score is ≥1. According to the underlying theory, a single affirmative response to any of the 10 items is sufficient to indicate the onset of nicotine dependence, as each symptom has face validity as an indicator of diminished autonomy.
Administration Format
Clinicians and researchers designed the HONC for maximum efficiency and ease of use.
- It takes less than 5 minutes to complete.
- It is a self-administered questionnaire that requires no special training.
- It is highly versatile and can be administered through all formats:
- Paper-based forms
- Digital (Online) platforms
- Mobile Apps
- Interview (In-person)
- Phone/Video call.
Applications of the Hooked on Nicotine Checklist (HONC)
The HONC is a highly practical tool with multiple applications:
- Screening: Its brevity and sensitivity make it an ideal tool for screening adolescents for early signs of nicotine dependence in school-based programs or primary care settings.
- Monitoring: Healthcare providers can use it to track the progression of dependence or monitor progress during cessation attempts.
- Treatment Planning: A positive HONC score can trigger early intervention and guide discussions about cessation strategies.
- Research: Researchers widely use the HONC to understand the natural history of nicotine dependence in youth, particularly in longitudinal studies like the DANDY study from which it originated.
Languages and Availability
The HONC has been translated and validated in several languages to support its use in global public health initiatives. Available versions include English, Spanish, and Chinese (Traditional). While content validity has been tested for a French-Canadian version, a full psychometric validation has not been published. The HONC is free to use for clinical and research purposes, with the copyright retained by its authors and the University of Massachusetts.
Reliability and Validity of the Hooked on Nicotine Checklist (HONC)
The HONC is recognized as a highly reliable and valid instrument for assessing the early stages of nicotine dependence.
- Internal Consistency: The scale demonstrates strong internal consistency, with a Cronbach’s alpha ranging from 0.83 to 0.90, indicating that its items cohesively measure the construct of lost autonomy.
- Validation Studies: The scale’s psychometric properties have been confirmed in numerous studies, including the Original validation study, the validations of the Spanish version and the Chinese version, ensuring its applicability in diverse adolescent populations. Furthermore, its content has been validated for the college students.
Limitations and Considerations
Despite its strengths, the HONC has several limitations that researchers and clinicians should consider:
- Self-Report Measure: As a self-report instrument, all responses are subjective and depend on the individual’s willingness and ability to report their experiences accurately.
- Cultural Bias: The questionnaire’s content may require cultural adaptation to be fully effective across different populations, a need that was addressed in its Spanish validation.
- Language Barriers: While available in several key languages, the HONC has not been translated and validated for all linguistic groups, which can limit its use in multicultural settings.
- Limited Validation Studies: The source material indicates that there are limited validation studies, suggesting more research may be needed to confirm its properties in certain specific subgroups or contexts.
- Narrow Focus: The tool has a narrow focus on identifying the loss of autonomy and the onset of dependence, making it less comprehensive for assessing addiction in long-term, heavy smokers.
- Age Restrictions: The HONC is specifically designed for adolescents and is not suitable for all age groups without appropriate adaptation.
- Social Desirability Bias: There is a risk that respondents, particularly adolescents, may provide answers they perceive as more socially acceptable rather than reporting their true behavior.
Other Versions and Related Questionnaires
- Other Versions: An adult version of the HONC has been adapted for use with older populations.
- Related Questionnaires: The HONC is often compared to the Fagerström Test for Nicotine Dependence (FTND), which focuses on consumption levels and is better suited for established smokers. Other related tools include the Modified Fagerström Tolerance Questionnaire, the CRAFFT 2.1+N for general adolescent substance use and the Nicotine Dependence Syndrome Scale (NDSS).

A Word from ResRef
The HONC uniquely captures the loss of autonomy – a core feature of nicotine dependence often missed by consumption-based tools (e.g., FTND). Its brevity, sensitivity in youth, and validation across many languages make it indispensable for early intervention in evolving tobacco/nicotine landscapes (e.g., vaping). Use alongside clinical assessments for comprehensive dependence evaluation.
