BACKGROUND: Prevention strategies to reduce @entity285 use/consumption among young @entity1 are crucial to reducing @entity285 -related @entity204 and preventing disease. This paper focuses on the effectiveness of a social networking site (SNS) @entity285 prevention program targeted toward young @entity1 . OBJECTIVE: We hypothesized that the program would diminish the relation made by @entity1 between @entity285 and festive moments, and would result in a reduction of their declared consumption of @entity285 at festive moments during the program. We also explored the interaction with the prevention program that was the most efficient. METHODS: The prevention program took the form of 3 lotteries over 2 years. The @entity1 periodically received prevention messages, particularly on @entity285 and festive moments (eg, videos on Facebook and short message service [SMS] text messages on their mobile phones). For the 3 periods, the @entity1 had to answer questions exploring the level of their belief that @entity285 consumption and festive moments are highly associated. A control group that did not participate in the prevention program was asked the same questions over the same number of days for the first 2 periods. During the second period, the @entity1 were asked to answer questions about their @entity285 consumption during parties. During the third period, we explored the interaction with the prevention program on the reduction of their belief that @entity285 consumption and festive moments are associated. RESULTS: A total of 651 @entity1 (age: mean 22.24, SD 4.10 years; @entity1 : n=430) during the first period, 301 @entity1 (age: mean 21.27, SD 3.07 years; @entity1 n=199) during the second period, and 305 (age: mean 22.41, SD 4.65 years; @entity1 : n=190) during the third period correctly completed the survey. For the control group, 69 students completed the survey during the first period (age: mean 18.93, SD 1.14 years; @entity1 : n=59) and 50 during the second (age: mean 20.78, SD 1.94 years; @entity1 : n=45). We observed a significant reduction in the association of @entity285 with festive moments in the @entity1 over the 2 years (period 1: z=-4.80, P<.001; @entity5394 : z=-2.11, P=.04; @entity5395 : z=-2.30; P=.02), but not in the controls. We also observed a reduction in the number of glasses consumed during festive moments for the @entity1 (z=-2.36, P=.02), but not for the controls during the second period. The third period showed that only the number of days since registration in the program had an impact on the reduction of the association of festive moments and @entity285 consumption (t21=3.186, P=.005). CONCLUSIONS: The findings of this study suggest that the SNS prevention program is promising in preventing the association of @entity285 with festive moments and, more generally, in impacting social norms.
