Description
Marijuana is currently the mostly widely used illicit drug in the U.S., and has been for multiple decades (Johnston et. al., 2016). Despite a growing belief that marijuana use is not harmful, over 4 million Americans have met criteria for marijuana use disorders in the past year alone (CBHSQ, 2015). According to marijuana trajectory studies, about a third of marijuana users will end up quitting later in life, but some \u2014 such as those who meet criteria for dependence \u2014 have a much greater difficultly quitting. Therefore, by looking at marijuana users who were successful in quitting, and comparing them to ongoing adult marijuana users, factors that may assist in helping an individual quit \u2014 such as certain motivations for quitting \u2014 may be identified. To study these issues, data was collected from 507 participants from the Pittsburgh Youth Study. It was found that adolescents who used marijuana weekly for at least one year were likely to be ongoing marijuana users in adulthood and that adolescents who had a warm relationship with their primary caretaker were likely to have quit marijuana by adulthood. It was also found that Black participants were more likely to have legal, monetary, and religious reasons for quitting than were White participants. Furthermore, participants who used regularly in adolescence were likely to list legal reasons, as well as a concern that marijuana use was needed to feel normal. Finally, it was found that not a single motivation for quitting marijuana was associated with a shorter period of abstinence. The implications of these findings for motivations to quit marijuana are the focus of the discussion.

Description
Blalock’s (1967) minority threat perspective is one of the most empirically investigated theories of crime control in criminological literature. A large body of research has tested this perspective and established a link between minority context and increased criminal justice controls. The perceived threat mechanisms hypothesized to facilitate this link, however, have received relatively scant attention. In addition, no multidimensional scale of perceived minority threat has been developed. These oversights have significantly impeded the advancement of research testing the empirical validity and generalizability of Blalock’s premises across racial and ethnic groups.
Against this backdrop, this dissertation extends prior work by conducting three separate but interrelated studies. The first study focuses on the development and validation of a multidimensional Perceived Latino Threat Scale (PLTS). The second study investigates how the PLTS can inform the relationship between Latino context and punitive border control sentiment. The third and final study assesses the psychometrics of another multidimensional scale of perceived threat—the Perceived Black Threat Scale (PBTS), and examines the structural invariance and distinctness of the PBTS and PLTS.
Using data collected from two college samples, I relied on a variety of different methods across the three empirical studies, including confirmatory factor analyses, bivariate and partial correlation analyses, and ordinary least squares regression. Overall, the findings suggest that both the PLTS and PBTS are multidimensional constructs that are structurally invariant and empirically distinct. In addition, perceived Latino threat significantly influenced punitive border control sentiment, but did not surface as a mediating mechanism linking ethnic context to immigration attitudes. Furthermore, whereas objective Latino population context did not demonstrate significant effects on either perceived Latino threat or punitive border control sentiment, the results emphasized perceived Latino context as a key moderator in the relationship between perceived Latino threat and punitive border control sentiment. Thus, the findings support the multidimensionality of perceived threat, as well as the hypothesized link between perceived threat and punitive controls, but raises key concerns about the generalizability of Blalock’s perspective to explain the threat-control process of Latinos. Implications for theory and research are discussed.
