Development and psychometric properties of the tobacco and nicotine consequences scale (TANCS) to screen for cigarette and e-cigarette misuse in community settings.

INTRODUCTION

To date, there are no existing measures of tobacco or nicotine misuse (i.e., negative consequences). The goal of the present study was to develop and test the psychometric properties of a novel scale, the Tobacco and Nicotine Consequences Scale (TANCS) to assess tobacco and nicotine misuse among cigarette smokers and e-cig users.

METHODS

This cross-sectional study collected data using an anonymous survey to assess tobacco and nicotine use expectancies, behaviors, and negative consequences of use. Of the 607 participants who attempted the survey, 491 participants (80.8%) completed the TANCS items. A split-half validation method was used to assess the structure and validity of the TANCS using exploratory and confirmatory factor analysis.

RESULTS

The exploratory factor analysis produced a five-factor solution, and the confirmatory factor analysis supported the factor structure with results providing an excellent fit to the data (CFI = 0.995, TLI = 0.994, RMSEA = 0.015, SRMR = 0.052). A total of 17 items were retained. The overall scale showed excellent reliability (α = 0.91) with subscale alphas between 0.68 and 0.90. The scale was significantly correlated to nicotine dependence and smoking expectancies, measured by the Fagerstrom Test Cigarette Dependence and Smoking Effects Questionnaire, respectively, suggesting the TANCS is a valid measure of tobacco and nicotine misuse. Total and subscale scores differed between participants preferring cigarettes or e-cigarettes.

CONCLUSIONS

The TANCS is a brief, reliable measure of tobacco and nicotine misuse that is correlated to tobacco and nicotine expectancies, use, and dependence. Future work should explore the test-retest reliability and incremental validity of the scale for tobacco use disorder.
