Table 4.
Factor loadings and inter-factor correlations in light and heavy drinkers. Significant loadings are bolded. In heavy drinkers, the factor structure was analogous to the full sample. In light drinkers SR was better summarized by a 3-factor solution where mean responses consisted of Stimulation/Hedonia, Craving/Motivation and a general negative valence factor, and dose responses consisted of a general positive valence factor, Sedation/Motor Intoxication and Negative Affect.
