The lifetime prevalence of amotivational syndrome was assessed in a group of 237 students at a Central European sports training facility using the criterion for amotivational syndrome formulated by Halikas, Weller, Morse, and Shapiro (1982). The group was regarded as being highly unlikely to have experienced an amotivational syndrome. The criterion for amotivational syndrome was met by 5.9% of the sample compared to 5.2% of Halikas et al.'s sample of regular marijuana users. The amotivational syndrome as measured by this criterion was not significantly associated with history of marijuana use. These results shed serious doubt on the validity of Halikas et al.'s study. No support is found for the amotivational syndrome hypothesis.
