Latent Classes of Adolescent Sexual and Romantic Relationship Experiences: Implications for Adult Sexual Health and Relationship Outcomes

Adolescents’ sexual and romantic relationship experiences are multidimensional but often studied as single constructs. Thus, it is not clear how different patterns of sexual and relationship experience may interact to differentially predict later outcomes. In this study we used latent class analysis to model patterns (latent classes) of adolescent sexual and romantic experiences, and then examined how these classes were associated with young adult sexual health and relationship outcomes in data from the National Longitudinal Study of Adolescent to Adult Health (Add Health). We identified six adolescent relationship classes: No Relationship (33%), Waiting (22%), Intimate (38%), Private (3%), Low Involvement (3%), and Physical (2%). Adolescents in the Waiting and Intimate classes were more likely to have married by young adulthood than those in other classes, and those in the Physical class had a greater number of sexual partners and higher rates of sexually transmitted infections (STIs). Some gender differences were found; for example, women in the Low-Involvement and Physical classes in adolescence had average or high odds of marriage, whereas men in these classes had relatively low odds of marriage. Our findings identify more and less normative patterns of romantic and sexual experiences in late adolescence and elucidate associations between adolescent experiences and adult outcomes.     

Social work students in the aftermath of Hurricanes Katrina and Rita: correlates of post-disaster substance use as a negative coping mechanism

Social work students’ post-disaster coping while in the field is an important workforce issue with ethical implications. The current study utilized secondary data collected in a previous study examining post-disaster alcohol and other drug (AOD) use among social work student volunteers (N = 416) in the wake of Hurricanes Katrina and Rita (HKR). The current sample included participants from the original study who responded to a single-item measure of AOD use as a negative coping mechanism (N = 290). The present study examined potential explanatory variables of AOD use in the aftermath of HKR, including demographic (age, gender, and race) and psychosocial characteristics (hurricane-related stressors, previous traumatic stressors, and post-traumatic stress). The multivariate logistic regression model distinguished between students who never or rarely used AOD and those who used AOD often to cope with HKR, accounting for 24% of model variance. Social work students who report post-disaster AOD use may risk experiencing additional, trauma-related vulnerabilities, should be further assessed, and provided necessary specialized supports to enable their well-being and to prevent impaired practice.     

Typical and Atypical Development of Visual Attention in 3‐ to 9‐Month‐Old Infants

The interactions between attention and stimulus encoding in infancy were examined using heart rate (HR) and visual habituation measures. At 3, 6, and 9 months of age, infants (N = 119) were habituated to an adult face; longest look (LL) duration was measured as an indicator of encoding speed. Three groups were formed based on LL change from 3 to 9 months: Large Decrease, Small Decrease, and Increase. Using concurrent electrocardiograph recordings, attention was measured through the percentage of looking time in orienting, sustained attention, and attention termination. We partially replicated previous findings regarding developmental patterns of attention in these three groups, notably that these patterns were different for the Increase group. Looks away from the stimulus were also assessed in each attentional phase and, as predicted, HR acceleration phases showed less visual engagement than HR deceleration phases. We also found anomalous behavior for the LL Increase group. In general, this small but distinct group showed similarities at 3 months to the presumably more mature behavior of typical 9 month olds, but by 9 months, they behaved more like typical 3 month olds regarding some, but not all, cognitive measures. These results are discussed in the context of the development of endogenous attention.     

Political influence across generations: partisanship and candidate evaluations in the 2008 election

Recent scholarship in political socialization has moved beyond traditional transmission models of parent-driven socialization to consider alternative pathways, like trickle-up socialization and its predictors. However, these studies have paid less attention to the diverse ways in which parents and children develop discrete political orientations, especially during a competitive presidential campaign. In this study, we examine various pathways through which influence occurs across generations in terms of partisanship and candidate evaluations. Our results suggest that while harmonious attitudes remain the norm, there are substantial opportunities for youth to demonstrate their independence, particularly when gaining perspectives from schools and digital media sources. Our findings indicate the importance of exploring how youth and their parents come to understand politics and the forces that shape youth socialization.     

Assessing LGBTQ campus climate and creating change

We report the findings of a climate study of a liberal arts college in Pennsylvania. This climate assessment was comprehensive in content (heterosexual and cisgender individuals' attitudes, and LGBTQ individuals' experiences), participants (faculty, staff, and students), and methodology (qualitative and quantitative). We found low levels of sexual prejudice and generally positive perceptions of the campus, but positive attitudes were more strongly endorsed by heterosexual and cisgender than LGBTQ participants. We consider the impact of these perceptions on LGBTQ students' co-curricular involvement and discuss the institutional changes that are underway as a result of our study.     

A competing risks model for correlated data based on the subdistribution hazard

Family-based follow-up study designs are important in epidemiology as they enable investigations of disease aggregation within families. Such studies are subject to methodological complications since data may include multiple endpoints as well as intra-family correlation. The methods herein are developed for the analysis of age of onset with multiple disease types for family-based follow-up studies. The proposed model expresses the marginalized frailty model in terms of the subdistribution hazards (SDH). As with Pipper and Martinussen’s (Scand J Stat 30:509–521, 2003) model, the proposed multivariate SDH model yields marginal interpretations of the regression coefficients while allowing the correlation structure to be specified by a frailty term. Further, the proposed model allows for a direct investigation of the covariate effects on the cumulative incidence function since the SDH is modeled rather than the cause specific hazard. A simulation study suggests that the proposed model generally offers improved performance in terms of bias and efficiency when a sufficient number of events is observed. The proposed model also offers type I error rates close to nominal. The method is applied to a family-based study of breast cancer when death in absence of breast cancer is considered a competing risk.     

US campus fraternities and sororities and the young adult injury burden

Objective: To investigate whether the presence of fraternities and sororities was associated with a higher local injury rate among undergraduate-age youth. Methods: In 2016 we compared the rate of 2010–2013 youth (18–24 years) emergency department (ED) visits for injuries in Hospital Service Areas (HSA) with and without fraternities and sororities. ED visits were identified in the State Emergency Department Database (n=1,560 hospitals, 1,080 HSAs, 16 states). US Census Bureau and National Center for Education Statistics sources identified HSA population and campus (n=659) characteristics. A proprietary database identified campuses with fraternities and sororities (n=287). ED visits explicitly linked to fraternities and sororities in the National Electronic Injury Surveillance System–All Injury Program were used to identify injury causes for sub-group analysis. Results: HSAs serving campuses with fraternities and sororities had lower age 18–24 injury rates for all causes except firearm injuries (no difference). Conclusions: Fraternities and sororities were not associated with a higher injury rate at the population level among undergraduate-age youth. A major limitation is not being able to observe campus health services utilization.
