“…Considerable research has shown that the Fagerström Test for Nicotine Dependence (FTND; Heatherton et al, 1991) has questionable psychometric properties, generally reflecting poor (Hughes, Oliveto, Riggs, Kenny, Liguori et al, 2004; Etter, Vu Da, & Perneger, 1999) to mediocre (Burling & Burling, 2003) properties of reliability and validity. The FTND has been shown to have poor internal consistency (Burling & Burling, 2003; Heatherton et al, 1991; Payne, et al, 1994; Pomerleau, et al 1994; Sledjeski et al, 2007; Steinberg, Williams, Steinberg, Krejci & Ziedonis, 2005), low construct validity (Etter et al, 1999), and poor predictive validity (Sledjeski et al, 2007).…”
