Since its first application to the measurement of alcohol use disorder in 2003 (Kahler, Strong, Stuart, Moore, & Ramsey, 2003), item response theory (IRT; Embretson & Reise, 2000) has been applied with increasing frequency to addictions research. Dichotomous and polytomous IRT models have been applied to measures of alcohol use disorder (Keyes, Krueger, Grant, & Hasin, 2011, and references therein), nicotine use disorder (Liu, Hedeker, & Mermelstein, 2013, and references therein), illicit drug use disorders (Saha et al., 2012, and references therein), and gambling behavior disorder (Sharp et al., 2012, and references therein). The goal of these studies was to determine to what extent an addictive disorder could be adequately represented as a unidimensional continuum rather than the traditional categories of “use,” “dependence,” “abuse,” and “addiction” (Orford, 2001).
