Much Ado About Missingness: A Demonstration of Full Information Maximum Likelihood Estimation to Address Missingness in Functional Magnetic Resonance Imaging Data

The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset (N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, when an auxiliary variable created to correlate r = 0.5 with fMRI task data was included, the performance of the FIML model improved, suggesting the potential value of FIML-based approaches for missing fMRI data when a strong auxiliary variable is available. In addition to primary methodological insights, the current study also makes an important contribution to the literature on neural vulnerability factors for obesity. Specifically, results from the full data model show that greater activation in regions implicated in reward processing (caudate and putamen) in response to tastes of milkshake significantly predicted weight gain over the following year. Implications of both methodological and substantive findings are discussed

Early executive control buffers risk for adolescent psychopathology during the COVID‐19 pandemic

Background: The coronavirus disease 2019 (COVID‐19) pandemic has had a global impact on youth mental health, and there is a critical need for research examining individual factors that contribute to increased psychopathology during the pandemic. The current study explored whether executive control (EC) abilities in early childhood interact with COVID‐related stress to attenuate risk for adolescent psychopathology during the first 6 months of the pandemic. Methods: Participants were 337 youth (49% female) living in a small midwestern city in the United States. Participants completed EC tasks when they were approximately 4.5 years old as part of a longitudinal study investigating cognitive development. At annual laboratory visits during adolescence and before the pandemic, participants (Mage = 14.57) reported on mental health symptoms. In July and August of 2020, participants (Mage = 16.57) reported on COVID‐related stress and depression, anxiety, and trauma symptoms. Results: COVID‐related stress was associated with increased internalizing problems after controlling for prepandemic symptom levels. Further, the impact of COVID-related stress on adolescent internalizing problems was moderated by preschool EC, with higher levels of EC buffering the effects of COVID‐related stress on adolescent internalizing problems. Conclusions: Findings highlight the importance of promoting EC early in development, as well as screening for EC deficits and implementing targeted intervention strategies across the lifespan to help reduce the impact of stress on adolescent internalizing problems

Mental Health Outcomes of Discrimination among College Students on a Predominately White Campus: A Prospective Study

Racial discrimination is a social stressor harmful to mental health. In this paper, we explore the links between mental health and interpersonal discrimination-related social events, exposure to vicarious racism via social media, and rumination on racial injustices using a daily diary design. We utilize data from a racially diverse sample of 149 college students with 1,489 unique time observations at a large, predominantly white university. Results show that interpersonal discrimination-related social events predicted greater self-reported anger, anxiety, depressive symptoms, and loneliness both daily and on average over time. Vicarious racism from day to day was associated with increased anxiety symptoms. In contrast, rumination was not associated with negative mental health outcomes. These findings document an increased day-to-day mental health burden for minority students arising from frustrating and alienating social encounters experienced individually or learned about vicariously

Race and ethnic variation in college students’ allostatic regulation of racism-related stress

Racism-related stress is thought to contribute to widespread race/ ethnic health inequities via negative emotion and allostatic stress process up-regulation. Although prior studies document racerelated stress and health correlations, due to methodological and technical limitations, they have been unable to directly test the stress-reactivity hypothesis in situ. Guided by theories of constructed emotion and allostasis, we developed a protocol using wearable sensors and daily surveys that allowed us to operationalize and time-couple self-reported racism-related experiences, negative emotions, and an independent biosignal of emotional arousal. We used data from 100 diverse young adults at a predominantly White college campus to assess racism-related stress reactivity using electrodermal activity (EDA), a biosignal of sympathetic nervous system activity. We find that racism-related experiences predict both increased negative emotion risk and heightened EDA, consistent with the proposed allostatic model of health and disease. Specific patterns varied across race/ethnic groups. For example, discrimination and rumination were associated with negative emotion for African American students, but only interpersonal discrimination predicted increased arousal via EDA. The pattern of results was more general for Latinx students, for whom interpersonal discrimination, vicarious racism exposure, and rumination significantly modulated arousal. As with Latinx students, African students were particularly responsive to vicarious racism while 1.5 generation Black students were generally not responsive to racism-related experiences. Overall, these findings provide support for allostasis-based theories of mental and physical health via a naturalistic assessment of the emotional and sympathetic nervous system responding to real-life social experiences

“Try Walking in Our Shoes”: Teaching Acculturation and Related Cultural Adjustment Processes Through Role-Play

In this article, we describe several role-playing exercises on acculturation and relevant cultural adjustment processes that we incorporated into Tomcho and Foel’s classroom activity on acculturation, and we report data that examine subsequent changes in students’ responses on pretest and posttest measures shortly after the activity and present qualitative themes derived from students’ reflections taken from an assignment at the end of the semester. We found no increases in students’ perceptions that role-playing can help them gain a better understanding of acculturation. However, there were increases in students’ awareness that acculturation is a real-world phenomenon, their understanding of how acculturation can impact people’s lives, and their sensitivity and empathy for people who face some of the challenges associated with acculturation, even after controlling for students’ pretest level of interest in cultural issues. Furthermore, thematic analyses indicated that students learned some of the challenges associated with acculturation and were able to label personal experiences associated with acculturation. They also gained concrete knowledge about and in-depth realization of the concept of acculturation. Instructors who teach psychology classes can use this exercise to complement traditional methods of teaching

"What's in a Game?" Acculturation and Drinking Game Behaviors Among Asian American Young Adults

Research on acculturation and drinking behaviors among Asian American young adults has yielded null and mixed findings. Moreover, very little is known regarding the link between acculturation and context-specific risky drinking activities, such as drinking games participation, in this population. Drinking games have been linked with a number of negative drinking outcomes; however, some games pose more risk than others. In the current article, we present a conceptual framework to delineate mechanisms that may underlie Asian American young adults' risk for participating in context-specific risky drinking activities and experiencing negative drinking consequences. We use a bidimensional approach to examine how acculturation might be directly or indirectly associated with negative drinking game consequences in a sample of Asian American young adults (N = 122; Mage = 22.1). Participants were recruited from Amazon's Mechanical Turk and completed an anonymous online survey. Controlling for age, gender, college student status (i.e., whether participants were currently enrolled in college), and typical alcohol use on nondrinking game occasions, lower levels of acculturation (i.e., low U.S./high heritage cultural orientations) were indirectly related to elevated levels of negative drinking game consequences through their association with increased frequency of participation in different types of drinking games, namely consumption and dice games. Given the null and mixed findings reported in the acculturation and alcohol use literature, careful attention to indirect effects could further researchers' understanding of the specific ways in which acculturation may increase Asian American young adults' risk for participating in risky drinking practices and experiencing negative drinking consequences

Validation of a Seven-Factor Structure for the Motives for Playing Drinking Games Measure

Playing drinking games can be characterized as a high-risk drinking activity because games are typically designed to promote heavy alcohol consumption. While research suggests that young adults are motivated to play drinking games for a variety of reasons (e.g., for thrills/fun, for the competition), the Motives for Playing Drinking Games measure has received limited empirical attention. We examined the psychometric properties of this measure with a confirmation sample of young adults recruited from Amazon’s MTurk (N = 1,809, ages 18-25 years, 47% men; 41% not currently enrolled in college) and a validation sample of college students (N = 671; ages 18-23 years; 26% men). Contrary to the 8-factor model obtained by Johnson and Sheets in a study published in 2004, examination of the factor structure with our confirmation sample yielded a revised 7-factor model that was invariant across race/ethnicity and college student status. This model was also validated with the college student sample. In the confirmation sample, enhancement/thrills and sexual pursuit motives for playing drinking games were positively associated with gaming frequency/consumption and negative gaming consequences. Furthermore, conformity motives for playing drinking games were positively associated with negative gaming consequences, while competition motives were positively associated with gaming frequency. These findings have significant implications for research and prevention/intervention efforts

Trouble Brewing: Pregaming Among High School and Incoming College Students

Pregaming (a.k.a., “prepartying,” “pre-funking,” or “predrinking”) consists of drinking before going to a social function or gathering where alcohol may or may not be served. Existing research suggests that pregaming in high school and pre-college (i.e., the period between high school graduation and the start of college) is widespread. Moreover, pregaming prevalence appears to rapidly increase after students graduate from high school and transition into college. Thus, the purpose of this brief review is threefold: (a) to summarize the existing (albeit limited) research on pregaming among high school students and incoming college freshmen, (b) to present an overview of the risk factors that have been identified for participation in pregaming, and (c) to discuss the implications for practice that may be particularly relevant for school-employed/affiliated nurses as well as health practitioners who work in college settings
