This study aimed to construct a hierarchy of motives linked to doping behaviors. Between 2000 and 2005, calls to a national antidoping phone-help service by 115 cyclists, 203 bodybuilders, and 40 footballers were analyzed. The results showed that the main motives were preserving health for cyclists, increasing muscular strength for bodybuilders, and personal recreation for footballers. However, in contrast to the literature, group influence was low and health preoccupations were high for cyclists; the influence of body image was relatively low for bodybuilders; and footballers cited muscular strength enhancement as a motive. The study's limitations are noted. The prevention campaigns therefore need to be specific.
