Mexican-origin adolescents' cumulative strengths predict baseline and longitudinal changes in self-growth outcomes.

This study adopts a cultural ecological perspective to examine how cumulative effects of external transcultural and cultural strengths are related to baseline and changes in three markers of Mexican-origin adolescents' self-growth (i.e., resilience, life meaning, and discipline). Using a three-wave longitudinal data set (5 years) of 604 adolescents, cumulative strengths (CS) was calculated, and growth curve analyses showed a similar pattern of findings for both transcultural and cultural cumulative strengths models: Adolescents with higher CS showed higher baseline resilience, life meaning, and discipline. While there were no significant associations between adolescents' CS scores and the increase in resilience, adolescents with higher CS scores showed steeper declines in life meaning and discipline (although these declines were no longer significant for cultural CS when transcultural and cultural CS were simultaneously tested in the same model). The findings emphasize a cultural ecological understanding of Mexican-origin youths' positive development from early to later adolescence. They also provide support for a CS model and have implications for positive psychology theories. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Survival Analysis and Socio-Cognitive Factors in the Timing of COVID-19 Vaccination Among Mexican-Origin Youth.

OBJECTIVE: The COVID-19 pandemic disproportionately affected ethnic minority populations and exacerbated preexisting health disparities. The current study aims to promote vaccine uptake among Mexican-origin youth from immigrant families by examining their time to COVID-19 vaccine uptake and assessing the influence of demographic, cognitive, and social factors on the incidence of COVID-19 vaccination. METHODS: The study conducted Survival Analysis using a Cox proportional hazards model based on a sample of 202 Mexican-origin youth (61.39% female; Mage = 20.41) with data collected from August 2021 to January 2023 in central Texas. RESULTS: The results show a critical time period for vaccine uptake (i.e., in the first six months after the vaccines were publicly available), evidenced by a surge decrease in COVID-19 unvaccination probability. In addition, more positive attitudes toward the COVID-19 vaccine (Hazard ratio/HR = 1.89, 95% Confidence Interval/CI = [1.64, 2.18]), greater motivation (HR = 2.29, 95% CI = [1.85, 2.85]), higher education levels (HR = 1.52, 95% CI = [1.24, 1.86]), and fewer general barriers to COVID-19 vaccine knowledge (HR = 0.75, 95% CI = [0.60, 0.94]) were associated with greater incidences of receiving COVID-19 vaccines at any given time point during the pandemic. CONCLUSION: The findings suggest that COVID-19 vaccine uptake among Mexican-origin youth occurred primarily within the initial months of vaccines being publicly distributed. To encourage vaccination among Mexican-origin youth, sustained COVID-19 vaccine promotion efforts are needed by targeting their motivation and positive attitudes and reducing barriers to vaccine information, particularly for youth with lower education levels.

Micrometer-thick and porous nanocomposite coating for electrochemical sensors with exceptional antifouling and electroconducting properties.

Development of coating technologies for electrochemical sensors that consistently exhibit antifouling activities in diverse and complex biological environments over extended time is vital for effective medical devices and diagnostics. Here, we describe a micrometer-thick, porous nanocomposite coating with both antifouling and electroconducting properties that enhances the sensitivity of electrochemical sensors. Nozzle printing of oil-in-water emulsion is used to create a 1 micrometer thick coating composed of cross-linked albumin with interconnected pores and gold nanowires. The layer resists biofouling and maintains rapid electron transfer kinetics for over one month when exposed directly to complex biological fluids, including serum and nasopharyngeal secretions. Compared to a thinner (nanometer thick) antifouling coating made with drop casting or a spin coating of the same thickness, the thick porous nanocomposite sensor exhibits sensitivities that are enhanced by 3.75- to 17-fold when three different target biomolecules are tested. As a result, emulsion-coated, multiplexed electrochemical sensors can carry out simultaneous detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid, antigen, and host antibody in clinical specimens with high sensitivity and specificity. This thick porous emulsion coating technology holds promise in addressing hurdles currently restricting the application of electrochemical sensors for point-of-care diagnostics, implantable devices, and other healthcare monitoring systems.

Language brokering profiles of Mexican-origin adolescents in immigrant communities: Social-cultural contributors and developmental outcomes.

This study examines social-cultural contributors and developmental outcomes of language brokers. From 2012 to 2020, three waves of data were collected from 604 Mexican-origin adolescent language brokers (Mage = 12.92, SD = 0.92, 54% girls). The study (1) identified four distinct subgroups of language brokers (efficacious, conservative, nonchalant, and burdened) who translated for mothers and fathers, after incorporating objective bilingual proficiency along with multiple dimensions of language brokering; (2) showed that early adolescents' Mexican, rather than U.S., cultural values and orientation were related to later language brokering profiles; and (3) showed that the efficacious group was the most resilient while burdened was the most vulnerable to developmental problems. Preservation of Mexican culture may facilitate language brokering experiences related to more positive developmental outcomes.

Comparing Drinking Game Motives, Behaviors, and Consequences among Varsity Athletes, Recreational Athletes, and Non-Student-Athletes: A Multisite University Study.

OBJECTIVE: Among college students, student-athletes are at increased risk for heavy alcohol consumption, participation in risky drinking practices (e.g., playing drinking games [DG]), and adverse alcohol-related consequences relative to non-student-athletes. Within the student-athlete population, level of sports participation (e.g., recreational or varsity sports) can affect alcohol use behaviors and consequences but our understanding of the extent to which level of sports participation influences engagement in DG is limited. Thus, in the present study, we examined differences in frequency of participation in DG, typical drink consumption while playing DG, negative DG consequences, and motives for playing DG among varsity, recreational, and non-student-athletes. METHOD: College students (N=7,901 across 12 U.S. colleges/universities) completed questionnaires on alcohol use attitudes, behaviors, and consequences. RESULTS: Student-athletes (recreational or varsity sports) were more likely to have participated in DG within the past month than non-student-athletes. Among students who reported past month DG play, recreational athletes played more often and endorsed more enhancement/thrills motives for playing DG than non-student-athletes, and student-athletes (recreational or varsity) endorsed higher levels of competition motives for playing DG than non-student-athletes. CONCLUSIONS: These findings shed light on some risky drinking patterns and motives of recreational athletes who are often overlooked and under-resourced in health research and clinical practice. Recreational and varsity student-athletes could benefit from alcohol screening and prevention efforts, which can include provision of competitive and alcohol-free social activities and promotion of alcohol protective behavioral strategies to help reduce recreational athletes' risk for harm while playing DG.

Peer-based discrimination and adolescent emotional and sleep health: A daily examination of direct and buffering associations.

Using 10-day daily diary data collected in 2019 from 10th grade students in southern U.S. (N = 161, 57% Latina/x/o, 21% Biracial, 10% Asian, 9% White, 4% Black; 55% female, Mage = 15.51), this study examined various forms of peer-based discrimination in adolescents' everyday lives. Results showed that personally experienced discrimination, peer racial teasing, and vicarious discrimination were frequent and impactful events. Results also provided strong evidence for the protective role of psychological resilience and some evidence for the protective-reactive roles of peer support and school climate in moderating the link between peer-based discrimination and daily well-being. The findings highlight the necessity to eliminate peer-based discrimination and shed light on interventions to reduce the harmful effects of peer-based discrimination on adolescents' daily well-being.

Short-term cortisol adaption to discrimination and Mexican-origin adolescents' mental and sleep health.

Discrimination experiences are a salient contributor to the health disparities facing Latina/x/o youth. The biopsychosocial model of minority health posits that discrimination influences health through wear and tear on the biological stress responses, including the hypothalamic-pituitary-adrenal (HPA) axis, which is a primary stress response system in the body. Emerging evidence suggests that discrimination alters the secretion of cortisol, the end product of the HPA axis, yet, whether the daily processes between discrimination and diurnal cortisol response influence mental and sleep health remains unanswered. This study integrated daily diary and post-diary survey data to examine whether daily diurnal cortisol responses to discrimination influence adolescents' mental (depressive symptoms, anxiety) and sleep (sleep quality, duration) health in a sample of Mexican-origin youth (N = 282; M age = 17.10; 55% female). Results showed that adolescents who experienced more discrimination across the four-day diary period exhibited steeper diurnal cortisol slopes and lower evening cortisol; however, such physiological responses tended to be associated with poorer adolescents' mental and sleep health. The current study underscores the potential adaptation cost associated with short-term cortisol adaptation in the face of discrimination.

Trajectories of discrimination among Chinese American youth: Variation, predictors, and outcomes.

Using 3 waves of longitudinal data from 444 Chinese American adolescents (Mage = 13.04 at Wave 1, 54% identified as women), the current study explored if there was variation in discrimination trajectories from early to late adolescence and whether contextual and individual factors predicted trajectories as well as if trajectories were associated with academic achievement and mental health. Three distinct discrimination trajectories were identified: low-increasing, moderate-stable, and high-decreasing. The results also revealed that neighborhood Chinese concentration and adolescents' acculturation predicted discrimination trajectories. Different trajectories were also associated with depressive symptoms; adolescents in the high-decreasing trajectory reported higher levels of depressive symptoms in late adolescence than in the other two trajectories. The findings highlight the heterogeneity in Chinese American adolescents' discrimination experience.

Acculturation and daily cigarette use among Mexican-origin youth: The moderating role of executive functions.

INTRODUCTION: Acculturation and enculturation have been conceptualized, respectively, as risk and protective factors for cigarette use. Although acculturation/enculturation orientations are often studied as stable characteristics, they represent a dynamic process influenced by individuals' social environments and can fluctuate across time. Therefore, investigating how youth actively navigate their acculturation and enculturation beliefs and behaviors on a day-to-day basis can advance scientific understanding of factors related to cigarette use. Executive functions, including inhibitory control, shifting, and working memory, are robust predictors of smoking (e.g., cigarette use). However, we know little about the protective role of executive functions on the daily level associations between acculturation/enculturation and cigarette use among Mexican-origin youth. OBJECTIVES: In a low-income Mexican-origin youth sample (M = 16.94, SD = 1.01; 52 % female), this study examined within-person associations between daily acculturation/enculturation and daily cigarette use and the moderating role of individual-level executive functions. METHOD: We captured the daily fluctuations of acculturation/enculturation and smoking by utilizing data from a 4-day daily diary. The study assessed inhibitory control, shifting, and working memory using behavioral paradigms. RESULTS: A multilevel logistic moderation model revealed statistically significant interactions between acculturation (but not enculturation) and all executive function skills predicting cigarette use. Higher daily acculturation levels were related to greater odds of daily cigarette use only for youth with lower levels of executive function skills. CONCLUSION: Findings suggest that interventions aimed at improving executive functions may protect Mexican-origin youth from the possible adverse effect of acculturation on cigarette use.

Change patterns of mother-adolescent perceived parenting and the corresponding trajectories in their internalizing symptoms.

Adolescence is a challenging and sensitive developmental period in which mothers and adolescents may be vulnerable to internalizing symptoms. The current study aimed to understand how patterns of changes in mother-adolescent perceived parenting (i.e., mother-adolescent perceived parenting transition profiles) corresponded with trajectories of mothers' and adolescents' internalizing symptoms from early to late adolescence. The current study utilized a three-wave longitudinal data set of 604 adolescents (54% female, Mage = 12.92, SD = 0.92) and 595 mothers (Mage = 38.89, SD = 5.74) from Mexican-origin immigrant families and adopted mother-adolescent perceived parenting transition profiles from a previous study. Multiple group analyses showed that mother-adolescent dyads who agreed on high levels of positive parenting across the course of adolescence (i.e., Stable Both High) experienced the lowest levels of internalizing symptoms, whereas dyads that showed an inconsistent pattern of mixed profile typologies over time (i.e., Fluctuated) experienced high levels of internalizing symptoms. For mother-adolescent dyads that consistently showed a pattern in which mothers reported more positive parenting compared to their adolescent children (i.e., Stable Mother High), mothers experienced low levels of (and even a decrease in) internalizing symptoms, while adolescents experienced considerably high levels of internalizing symptoms over time. The results for the other two parenting transition profiles (i.e., Change to Both High and Change from Both High) are also discussed. The findings highlight the importance of developing separate adaptive interventions to reduce internalizing symptoms for mothers and children by considering their change patterns of perceived parenting during the course of adolescence.

A national study on pregaming motives, frequency, consumption, and negative alcohol consequences among university students in the United States.

BACKGROUND: Pregaming, or drinking before going out, is a commonly practiced risky behavior. Drinking motives are well-established predictors of alcohol use and negative alcohol consequences. Given the influence of context on drinking practices, motives specific to pregaming may affect pregaming behaviors and outcomes above and beyond general drinking motives. Thus, we examined how pregaming motives are related to pregaming behaviors and negative alcohol consequences. METHODS: Using data from two national cross-sectional online studies, the current study included undergraduates who pregamed at least once in the past month (n=10,200, Mage=19.9, women=61%, white=73.6%; 119 U.S. universities). Participants completed assessments of demographics, general drinking motives, pregaming motives, pregaming frequency/consumption, and negative alcohol consequences. Data were analyzed using hierarchical linear models accounting for nesting of participants within sites. RESULTS: When controlling for demographic factors and general drinking motives, interpersonal enhancement motives and intimate pursuit motives were positively associated with pregaming frequency, pregaming consumption, and negative alcohol consequences. Situational control motives were negatively associated with pregaming consumption and negative alcohol consequences. Barriers to consumption motives were negatively associated with pregaming frequency but positively associated with negative alcohol consequences. CONCLUSIONS: Students who pregame to make the night more fun or to meet potential dating partners appear to be at particular risk for negative alcohol consequences. Motives may be modifiable, particularly via cognitive/behavioral strategies. Findings suggest that specific motives may be appropriate intervention targets when trying to reduce pregaming behaviors and negative alcohol consequences.

The Association of Ethnic and American Identities with Psychological Well-Being among Latinx Emerging Adults: The Mediating Role of Bicultural Identity Integration.

Latinx emerging adults explore and commit to their ethnic and American identities which may influence their psychological well-being. However, it may not be the act of exploring and committing to their ethnic and American identities that influence emerging adults' psychological well-being; instead, it may be how they integrate both identities. To test this possibility, this study tested whether ethnic and American identity exploration and commitment were associated with psychological well-being by way of two bicultural identity integration processes (i.e., blendedness and harmony) among Latinx emerging adults. Data came from a year-long three-wave longitudinal study about stress and well-being among Latinx first-years (70% female; Mage = 18.20; SD = 0.51) with Wave 1 collected in Fall 2020, Wave 2 in Spring 2021, and Wave 3 in Fall 2021. Cross-sectional and longitudinal structural equation modeling suggest ethnic identity exploration and American identity commitment to be associated with psychological well-being by way of bicultural identity integration blendedness (i.e., perceived cognitive overlap between identities) and harmony (i.e., perceived affective conflict between identities). Results point to ethnic and American identity exploration and commitment being related with blendedness and harmony, which, in turn, were related with psychological well-being in the moment but not over time.

Perceived Parenting Discrepancy Profiles, Feelings about Language Brokering, and Internalizing Symptoms among Mexican-origin Adolescents in Immigrant Families.

While different patterns of perceived parenting discrepancy among mother-adolescent dyads have been shown to be associated with adolescent internalizing symptoms, little is known about the pathway underlying such associations, particularly among immigrant families. The current study considered one culturally salient form of mother-adolescent communication, language brokering (i.e., adolescents translating and interpreting between host and heritage languages for mothers), in order to investigate its mediating role based on two waves of longitudinal data on Mexican-origin immigrant families. Wave 1 included 604 adolescents (54% female; Mage = 12.92, SD = 0.92) and 595 mothers (Mage = 38.89, SD = 5.74); Wave 2 was collected one year later with data from 483 adolescents. Perceived parenting discrepancy patterns at Wave 1 were captured by three profiles based on the levels of both mothers' and adolescents' perceived positive parenting (i.e., Mother High, Adolescent High, and Both High). Compared to the other two profiles, adolescents who reported much lower positive parenting than mothers at Wave 1 (i.e., Mother High) experienced more negative feelings about brokering at Wave 2, relating to more anxiety. Being in the Mother High (vs. Both High) group was also directly related to more depressive symptoms one year later. This study highlights the importance of considering culturally salient forms of communication, such as language brokering, when designing family-level interventions to reduce adolescents' internalizing symptoms by building agreement on high positive parenting among mother-adolescent dyads from immigrant families.

COVID-19 Anti-Chinese Discrimination, Current Pandemic Stress, And Adolescents' Mental Health.

The current study investigated adolescents' experiences of COVID-19 anti-Chinese discrimination (i.e., vicariously witnessed, directly experienced), the consequences for mental health, and the moderating role of general pandemic stress. During Summer 2020, 106 adolescents (43% Latino/a/x, 19% Asian American, 13% Black/African American, 26% biracial/multiracial/other; 58% female) participated in a 14-day daily diary study. Path analyses revealed that more experiences of vicarious COVID-19 anti-Chinese discrimination were associated with greater anxious mood, depressed mood, and mental health stress, while direct COVID-19 anti-Chinese discrimination was unrelated to mental health outcomes. The interaction between vicarious COVID-19 anti-Chinese discrimination and general COVID-19 stress was significant for depressed mood; simple slope analyses showed that for adolescents reporting high levels of COVID-19 stress, more frequent experiences of vicarious COVID-19 anti-Chinese discrimination were associated with greater severity in depressed mood, but this link was nonsignificant for those reporting low levels of general pandemic stress. Findings from the current study underscore the pernicious effects of vicarious COVID-19 anti-Chinese discrimination on the mental health of minoritized youth beyond solely Asian Americans. Additionally, the results evince the need for future pandemic-response efforts to craft public health messaging that avoids the racialization of disease and subsequent stigmatization of ethnic-minority communities.

Parents' adaptation from conflict: Bicultural socialization beliefs and acculturative family conflict in Chinese American families.

Many Chinese American parents desire for their children to take on both Chinese heritage and mainstream American values and behaviors, referred to as their bicultural socialization beliefs. Parents' development of such beliefs appears linked with parent-adolescent conflict concerning cultural values, yet the direction and temporal ordering of this relation is unclear. The present study aimed to resolve discrepancies in the literature through examining the bidirectional relations between Chinese American parents' bicultural socialization beliefs and the acculturative family conflict they experience with their children. Relations were examined across two developmental periods of the children: adolescence and emerging adulthood. Data came from a longitudinal study of 444 Chinese American families from the west coast of the United States. Mothers and fathers reported on their own bicultural socialization beliefs for their children. Mothers, fathers, and adolescents/emerging adults each reported on levels of acculturative family conflict within mother-adolescent and father-adolescent dyads. Higher levels of family conflict in adolescence consistently predicted greater increases in parents' desires for their children to be bicultural in emerging adulthood. Results have implications for interventions with Chinese American families and demonstrate Chinese American parents as capable of adapting and growing from challenging, culturally based interactions with their children.

Prospective Effects of Discrimination, Depressive Symptoms, and Cognitive Control Among Mexican-Origin Women.

OBJECTIVES: Cognitive control predicts functional independence and cognitive health outcomes, but is yet to be known the extent to which social stress, like discrimination, may diminish cognitive control capacities in Mexican-origin women. We evaluated the prospective associations between everyday and ethnic discrimination on cognitive control and examined the mediating effects of depressive symptoms on these links. We further examined the extent to which associations varied by age and financial strain. METHODS: We used data from 596 Mexican-origin women (average age = 38.89, standard deviation = 5.74) who participated in a 3-wave longitudinal study spanning 8 years (from 2012 to 2020). Participants completed measures of everyday and ethnic discrimination at Wave 1, depressive symptoms in Waves 1 and 2, and completed computer-based tasks of cognitive control at Wave 3. Self-reported assessments of financial strain were completed at Wave 2. Moderated mediation structural equation models were implemented to test hypotheses. RESULTS: Depressive symptoms significantly mediated the prospective association between everyday/ethnic discrimination to cognitive control. Higher levels of everyday and ethnic discrimination at baseline were associated with more depressive symptoms at Wave 2, which were then related to poorer cognitive control (i.e., longer reaction time in congruent and/or incongruent trials) at Wave 3. There was no significant moderation of age. Among those with low financial strain, higher levels of everyday discrimination were related to faster response times. DISCUSSION: Results revealed the long-term consequences of experiences with discrimination on cognitive control that operate through increased depressive symptoms and that may have some subtle differential effects across levels of financial strain.

Innovative theory and methods for the next generation of diversity, equity, and inclusion sciences: Introduction to the special issue.

Diversity, equity, and inclusion sciences were invigorated by Plaut's (2010) landmark publication "Diversity science: Why and how difference makes a difference." As this field has expanded over the last decade, it is timely to reflect on its current state and future directions. The goal of this special issue is to bring together a collection of articles that advance innovative theory and methods for the next generation of diversity, equity, and inclusion sciences. The articles in this special issue cover cutting-edge themes, such as critical research methods for liberation, healing, and reconciliation; advancing intersectional theory and methods; innovative theory and methods on individual-social dynamics; promoting equity and advancing research on culture, ethnicity, and race; and new approaches to measuring and overcoming racism.

Demographic and Psychosocial Characteristics, Air Pollution Exposure, and Housing Mobility of Mexican Immigrant Families.

OBJECTIVE: People of color and lower socioeconomic status groups in the USA, including those of Mexican origin, are exposed to higher concentrations of air pollution, including fine particulate matter (PM2.5). Associations were examined between neighborhood air pollution levels and the psychosocial and demographic characteristics of linguistically isolated Mexican-origin immigrant families. Housing mobility and changes in air pollution levels due to changes in residence were also examined. METHODS: A sample of 604 linguistically isolated Mexican-origin families in central TX provided data on demographic and psychosocial experiences. Outdoor air pollution concentrations at participants' home addresses were based on high-resolution estimates of fine particulate matter (PM2.5) and its constituents. Movers were identified as families whose residential addresses changed during the study period; these participants were further grouped and compared based on the change in their residential PM2.5 concentration from before to after their move. RESULTS: Lower PM2.5 concentrations were associated with reports of more ethnic discriminatory experiences, higher socioeconomic status, and higher perceived neighborhood safety. Among the 23% of families who changed residences, PM2.5 concentrations were generally lower at the new family address. Families with mothers reporting a greater sense of neighborhood safety or acculturation levels tended to move from one area low in air pollutants to another, and mothers reporting the lowest levels of neighborhood safety or acculturation tended to move from one area high in air pollutants to another. CONCLUSION: There are limits to assimilation for Mexican immigrant families. Living in more advantaged neighborhoods is associated with experiencing better air quality, but this advantage may come at the cost of experiencing more ethnic discrimination.

Mother-Adolescent Perceived Parenting Profiles and Mexican-origin Adolescents' Academic Performance.

Mothers and adolescents often perceive parenting differently, but it is unclear how different profiles of mother-adolescent perceived parenting and developmental transitions of such profiles would influence adolescent academic performance longitudinally. The current study adopted a three-wave dataset of 604 Mexican-origin adolescents (54% female; Mwave1.age = 12.92 years) and 595 mothers. Adolescents who agreed on high levels of positive parenting with their mothers in early adolescence (i.e., the Both High group) and stayed in the Both High group demonstrated the best academic performance in late adolescence. However, adolescents who changed from the Both High group in early adolescence and ended with discrepancies in perceived parenting or an agreement on low positive parenting with mothers in late adolescence had the worst academic performance. The findings suggest the plasticity of mother-adolescent relationships during adolescence, which can be an intervention target to improve Mexican-origin adolescent academic performance.

Awareness of postural orthostatic tachycardia syndrome is required in adolescent syncope.

We investigated head-up tilt test (HUTT) results across age-groups in syncope/presyncope patients to establish pediatric postural orthostatic tachycardia syndrome (POTS) characteristics. We retrospectively reviewed syncope patients' medical records. Adolescents were defined as 10 to 19 years old, adults as 20 to 59 years old, and older individuals as ≥60 years old. From HUTT results, we determined POTS prevalence and differences among the age-groups. We included 147 adolescents, 269 adults, and 123 older patients. Seventy (13.0%) patients (61.4% females; median age: 20 [17-25] years) were diagnosed with POTS. The syndrome was more prevalent among adolescents (33 [22.4%]) than adults (37 [13.8%]), and was absent among older individuals. Affected adolescents had significantly lower resting diastolic blood pressure (DBP) and heart rate (HR), and converted to maximum HR more rapidly than adolescents without the syndrome during the passive phase. Adolescents with POTS demonstrated several unique characteristics compared to adults with and adolescents without this syndrome. POTS may be underrecognized among syncope and presyncope patients, among which 22.4% of adolescents were diagnosed with the syndrome. POTS should be considered when evaluating syncope patients.
