The Fagerström Test for Nicotine Dependence (FTND) is frequently used to assess the level of smokers’ nicotine dependence; however, it is unclear how to manage missing items.
This ambiguity may lead researchers to discard participants with incomplete FTND data, which can lead to loss of power and bias. Other prominent questionnaires (such as the Functional Assessment of Cancer Therapy General and the Hospital Anxiety and Depression Scale) have published recommendations for how to manage missing items. To our knowledge, there are no published recommendations for how to manage missing items in the FTND. To investigate different methods for managing missing items in the FTND, we performed a simulation study using data from the Arizona Smokers’ Helpline (ASHLine).
