Contextualized in the organ donor registration domain, the current study assessed whether overtly listing eligibility requirements impairs the accuracy of data collected on MTurk. On day 1, the first and third round of data collection did not list eligibility requirements; the second and fourth round overtly listed a qualification requirement: status as a non-registered organ donor. On day 2, the approach was identical, except the order was reversed-the first and third round overtly listed the study qualifications, while the second and fourth did not. These procedures provided eight different waves of data. In addition, all participants were randomly assigned to read an elevating (i.e., morally inspiring) story or a story not inte...

The current study was designed to test whether the number of marijuana offers received provides an indirect path between parental knowledge and adolescents' marijuana use. Methods: Data from the nationally representative National Survey of Parents and Youth were examined. Analysis 1 tested the association between frequency of being offered marijuana and adolescents' (N = 4264) marijuana usage in the subsequent year. Analysis 2, spanning a three-year time frame, tested whether the frequency of marijuana offers at the second year of the panel study bridged the relationship between parental knowledge in Year 1 and marijuana use in Year 3. Results: Analysis 1 indicated that the frequency with which adolescents were offered marijuana predicted usage one year later, after controlling for previous usage and nine other common predictors of marijuana use. Analysis 2 revealed an indirect relationship between parental knowledge and use through the number of marijuana offers the adolescent received. Conclusion: There was a strong link between the number of offers received and adolescents' future marijuana use. Higher parental knowledge predicted reductions in offer frequency, which was associated with lower levels of marijuana use. Reducing the number of marijuana offers an adolescent receives could serve as a useful focus for intervention programs targeting parents.
