of alcohol craving with a genetic variant (Foroud et al., 2007), the inclusion of craving may be useful for progress in genetic epidemiology. More analyses with diverse, genetically-informative data would be useful to fully understand the phenotypic implications of alcohol craving. Further, research clarifying the role of depression and other psychopathology in the experience of craving would be useful. On the other hand, the lack of additional cases suggests that craving is largely redundant with existing criteria. Clinical case finding would not improve given the addition of a craving criterion, raising doubts about the added benefit of the criterion in the context of the existing symptoms. Further analyses and replications in diverse samples of clinical, adolescent, and genetically-informative individuals would aid in the elucidation of craving utility in a variety of contexts.
