Managing missing items in the Fagerstrom Test for Nicotine Dependence: a simulation study.

ABSTRACT:

Background

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. The aim of this study was to investigate different methods for managing missing items in the FTND.

Methods

We performed a simulation study using data from the Arizona Smokers' Helpline. We randomly sampled with replacement from the complete data to simulate 1000 datasets for each parameter combination of sample size, proportion of missing data, and type of missing data (missing at random and missing not at random). Then for six methods for managing missing items on the FTND (two involving no imputation and four involving single imputation), we assessed the accuracy (via bias) and precision (v
