| dc.description.abstract | This study investigated the theory of planned behavior (TPB) with a potential moderator interaction of the ecstasy use of friends, in relation to ecstasy use of the young adult. A cross-sectional survey was completed by 384 young adults (M age = 22.56 years, SD = 1.76) to measure components of the TPB and use of ecstasy by friends and the young adults themselves. Regression analyses showed that only attitudes towards ecstasy use (of the TPB) were significantly related to ecstasy use, and this relation was fully mediated by intentions to use ecstasy. There was a significant interaction between intentions and the ecstasy use of friends: the relation between intentions and ecstasy use was significantly stronger for young adults with more friends who use ecstasy. This interaction was not significant when the ecstasy use of friends was dichotomized to having or not having friends who use ecstasy. Having friends who use ecstasy does not directly affect the relation between intentions and ecstasy use by young adults. The findings provide some support that the ecstasy use of friends is an important determinant to explain why intention leads to actual ecstasy use of the young adult. | |
