The objectives of this study were (1) to review systematically Skog's theor
y of collective drinking behaviour and its interpretations by alcohol resea
rchers, and (2) to give examples of how Skog's theory and these different i
nterpretations have been empirically tested and to indicate how they might
be tested. Based on a computer-aided search of the literature, a reconstruc
tion of the theory and possible alternative interpretations is provided. Di
fferent interpretations of Skog's theory are possible and can be found in t
he literature. Surprisingly, there is little empirical evidence, especially
recent evidence, to support Skog's key assumptions. Suggestions for furthe
r research are given.
