Abstract
I wanted to examine whether the factor structure of the Questionnaire of Smoking Urges (QSU; Tiffany & Drobes, 1991) was best represented by a one, two, or four-factor structure in two culturally distinct samples of smokers from Spain and the U.S., respectively. I also sought to develop a Spanish shorter version of the QSU and to cross-validate my findings using an American sample of smokers. The Spanish version of the QSU (QSU-Spanish) was administered to undergraduates from two Spanish universities (n = 259). I used confirmatory factor analysis (CFA) techniques to compare the fit of an a priori theorized four-factor model with the two-factor model originally reported for the QSU (Tiffany & Drobes, 1991). The same analyses were conducted in a reanalysis of Tiffany & Drobes' data. The two-factor model provided the best fit for the data in both samples but left room for improvement in the Spanish sample. Thus, we revised the measure to produce a briefer instrument with better fit for the Spanish data. This resulted in a 15-item QSU-Spanish measure. This structure was cross-validated using the data collected by Tiffany and Drobes (1991) for the development of the English version of the QSU. CFA indicated [that the two-factor] model for the QSU15 also fit the data well in the sample of American students. However, the measurement equivalence of the instrument across groups was partial. Overall, the results supported the notion that the craving construct is best conceptualized as a multidimensional rather than a unidimensional motivational state.
