Posttraumatic stress disorder symptoms, physiological reactivity, alcohol problems, and aggression among military veterans

This study examined the association between posttraumatic stress disorder (PTSD) symptomatology and aggressive behavior among a sample of male Vietnam veterans (N = 1,328). Results indicated that the hyperarousal PTSD symptom cluster evidenced the strongest positive association with aggression at the bivariate level when compared with the other PTSD symptom clusters. When the PTSD symptom clusters were examined together as predictors, hyperarousal symptoms evidenced a significant positive relationship with aggression, and avoidance/numbing symptoms were negatively associated with aggression. Examination of potential mediators indicated that hyperarousal symptoms were directly associated with aggression and indirectly related to aggression via alcohol problems. Reexperiencing symptoms were associated with aggression only indirectly and through their positive association with physiological reactivity and negative association with alcohol problems. Study results highlight the complexity of the relationship between PTSD symptoms and aggression, and suggest possible mechanisms explaining this association.     

Survey Experiments on Candidate Religiosity,Political Attitudes,and Vote Choice

Because identification with and affect toward social groups is a primary heuristic for citizens, the social group profiles of candidates are important for electoral behavior. We focus on an increasingly important element of candidates’ social characteristics: their levels of religiosity and secularism. We argue that as religious groups and identities become structured less by what religion they are and more by how religious they are (or are not), candidate religiosity and secularism should condition the impact of political orientations such as partisanship and cultural policy attitudes on vote choice. Highly religious candidates should attract more support from Republicans and from cultural conservatives, while overtly secular candidates should appeal more to Democrats and cultural liberals. Using a survey experiment in which respondents evaluate a state legislative candidate with varying levels of religiosity and secularism, we find strong support for our argument.     

The performance of two pathological gambling screens in college students

The psychometric properties of two pathological gambling (PG) screening instruments, the South Oaks Gambling Screen (SOGS) and the Massachusetts Gambling Screen-DSM-IV subscale (MAGS), were explored in a sample of college students (N = 159). Participants completed the two screening instruments, a diagnostic interview for PG, the Gambling-Timeline Followback (G-TLFB), Gambling Self-Efficacy Questionnaire (GSEQ), and the Hopkins Symptom Checklist (HSCL). Both screening measures were found to have adequate internal consistency and were highly correlated with each other and the diagnostic interview. The screening measures demonstrated convergent and discriminant validity. Using the diagnostic interview as the criterion measure, the SOGS demonstrated better sensitivity in identifying PG college students than the MAGS. The MAGS demonstrated better specificity in identifying non-PG college students than the SOGS. The results of this study suggest that although neither measure is perfect in identifying PG college students, the SOGS is a more appropriate measure for screening purposes.     

The Electoral Impact of Public Opinion on Religious Establishment

While previous work has examined the structure of public opinion on church and state, to date there has been little effort to connect public opinion on this group of issues to vote choice. I begin by hypothesizing that attitudes on religious establishment are distinct from attitudes on more often studied issues like abortion and gay marriage. Second, I argue that religious establishment meets the conditions for partisan voting: the parties and candidates have taken distinct, highly public stands on religious establishment, and the issue is highly salient among a certain segment of voters. Finally, I develop a theory that establishment attitudes should exert a greater impact among those individuals who feel that their values are threatened in contemporary society because such individuals may see religious accommodation as a means of returning to their understanding of traditional values. I test these hypotheses using data from the 2008 Cooperative Campaign Analysis Project, and I find considerable support for my argument.
