This study reports the factorial structure of the scale used in a prevention program, to assess the risk of alcoholconsumption among Schoolchildren. The sample of 3134 students was split in order to obtain two sub-samples. With thefirst sample, an exploratory factorial analysis served to establish a basic five-factor structure. The confirmatory factorialanalysis, using the second sample, achieved a structural model with good adjustment indicators both the whole modeland the measures models included. This instrument is an advance in the context of prevention programs; however, it isnecessary to obtain more evidence about the properties about it.
