The empirical testability of Skog's theory of collective drinking behaviour.

The objects of this study we (1) to review systematically Skog's theory of collective drinking behaviour and its interpretations by alcohol researchers, and (2) to give examples of how Skog's theory and these different interpretations have been empirically tested and to indicate how they might be tested. Based on a computer-aided search of the literature, a reconstruction of the theory and possible alternative interpretations is provided. Different interpretations of Skog's theory are possible and can be found in the literature. Surprisingly, there is little empirical evidence, especially recent evidence, to support Skog's key assumptions. Suggestions for further research are given.
