Preliminary analyses found that no factor-analytic solution was applicable across all countries and for both genders. Therefore, for the present purposes, we have constructed item groupings based on construct similarity of the items. In grouping the consequences items, we took into consideration the commonly-made distinction between dependence and other types of negative consequences, as well as the five domains defined for the Drinker Inventory of Consequences (DrInC) developed for Project MATCH in the US (43). Our groupings also take into consideration endorsement rates of items in order to avoid scales being dominated by one or two commonly endorsed items. Based on these considerations, we constructed three groupings.
