Immigration stress and maternal sensitivity in a Mexican immigrant sample: The role of parasympathetic activity and familism value.

OBJECTIVES: The present study examined whether immigration stress was related to decreased capacities for psychophysiological stress regulation (as indexed by respiratory sinus arrhythmia [RSA]) and whether lower RSA, in turn, was related to decreased maternal sensitivity. The buffering effect of familism values was also evaluated, such that familism values were expected to minimize associations between immigration stress, RSA, and sensitivity. METHOD: Data were drawn from a longitudinal study of Mexican immigrant mothers (N = 277; Mage = 28 years). Mothers self-reported immigration stress and familism values, and mothers' resting RSA and sensitivity were assessed during laboratory visits. RESULTS: Higher immigration stress was associated with higher RSA (B = .15, SE = .07, p = .04) but was unrelated to maternal sensitivity. Moreover, links between more immigration stress and higher RSA were more pronounced among mothers who reported stronger familism values (B = .20, SE = .07, p = .003). CONCLUSIONS: The present study contributes to our understanding of the sequelae of immigration stress in Mexican immigrant mothers and the cultural resiliency factors that may alter its effects. In contrast to hypotheses, findings suggested that mothers who endorse more immigration stress may also exhibit higher RSA, and links may be more pronounced among those with strong familism values. Further research is needed to advance understanding of resiliency processes that promote family functioning in vulnerable populations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Dampened psychobiological responses to stress and substance use in adolescence.

Substance use increases throughout adolescence, and earlier substance use may increase risk for poorer health. However, limited research has examined whether stress responses relate to adolescent substance use, especially among adolescents from ethnic minority and high-adversity backgrounds. The present study assessed whether blunted emotional and cortisol responses to stress at age 14 related to substance use by ages 14 and 16, and whether associations varied by poverty status and sex. A sample of 277 Mexican-origin youth (53.19% female; 68.35% below the poverty line) completed a social-evaluative stress task, which was culturally adapted for this population, and provided saliva samples and rated their anger, sadness, and happiness throughout the task. They also reported whether they had ever used alcohol, marijuana, cigarettes, and vaping of nicotine at age 14 and again at age 16. Multilevel models suggested that blunted cortisol reactivity to stress was associated with alcohol use by age 14 and vaping nicotine by age 16 among youth above the poverty line. Also, blunted sadness and happiness reactivity to stress was associated with use of marijuana and alcohol among female adolescents. Blunted stress responses may be a risk factor for substance use among youth above the poverty line and female adolescents.

Dispositional Active Coping Predicts Patterns of Adolescents' Cortisol Responsivity in the Context of School-related Stressors.

OBJECTIVE: The goal of this study was to examine the direct and conditional effects of active coping and prior exposure to school-related stressors on cortisol reactivity and recovery in response to an academically salient, social stress task. METHOD: Participants included N= 758 adolescents (50% male; M age = 12.03 years, SD = .49) enrolled in the 7th grade in Title 1 middle schools. Adolescents were predominantly ethnic minorities (62% Hispanic, 12% non-Hispanic White, 11% non-Hispanic Black, 7% Native American, and 8% "other"). Youth completed self-reported assessments of their dispositional use of active coping strategies, prior exposure to school hassles, pubertal status, medication use, and relevant demographic information. In addition, youth engaged in an academically salient group public speaking task adapted for adolescents and provided salivary cortisol sample pre-task, immediately post-task, 15-, and 30-minutes post-task. RESULTS: Results from piecewise latent growth curve modeling revealed that active coping independently predicted lower cortisol reactivity to the stress task. Furthermore, active coping was associated with slower cortisol recovery when adolescents reported not having experienced any school hassles in the past three months and faster recovery when having experienced several school hassles in the past three months. Results from multinomial logistic regressions revealed that greater use of active coping strategies was less likely to predict a hyper-reactive pattern of cortisol responding compared to other patterns. CONCLUSION: Findings provide support for active coping as a way to promote adaptive physiological responding to school-related stressors among ethnically diverse youth residing in low-income communities.

Intergenerational Consequences of Maternal Childhood Maltreatment on Infant Health Concerns.

INTRODUCTION: Childhood maltreatment is a well-established risk factor for health problems in adulthood and may also have intergenerational consequences for infant health. Childhood maltreatment may confer risk for infant health by undermining caregiver capacities for sensitive and responsive caregiving. However, associations among childhood maltreatment, maternal sensitivity, and infant health are not well understood. These processes may be of particular importance among low-income and ethnic minority populations for whom disparities in maltreatment exposure and poorer health outcomes are well-established. METHOD: The current study drew data from a sample of low-income, Mexican American families to examine whether maternal childhood maltreatment would be associated with more infant health concerns, and whether lower maternal sensitivity would explain their associations. Data were collected from 322 mother-infant dyads during home visits completed during pregnancy and when infants were 12, 18, and 24 weeks old. RESULTS: Maternal childhood maltreatment exposure and lower maternal sensitivity were both associated with more infant health concerns. Maternal childhood maltreatment was not associated with maternal sensitivity. DISCUSSION: These findings highlight potential intergenerational consequences of maternal childhood maltreatment for infant health and underscore a need for evaluating pre- and postnatal mechanisms through which these effects may be perpetuated. Furthermore, results indicate that maternal sensitivity may represent a promising target for interventions seeking to counteract intergenerational transmission processes. Clarification about underlying risk processes and potentiating resiliency characteristics may elucidate ways to better support mothers and infants across the lifespan.

Childhood maltreatment is associated with a variety of health outcomes across an individual's lifespan and may have intergenerational consequences as well. The present study is among the first to investigate maternal co-regulatory behaviors (i.e., sensitivity) as a potential mechanism through which maternal exposure to childhood maltreatment may influence infant health concerns. Results suggest that both maternal childhood maltreatment history and sensitivity may shape infant outcomes before 24 weeks of age. Increasing understanding of the mechanisms through which maternal childhood maltreatment may exert cascades of influence on infant health may help to inform the development of early intervention services.

Are Discrepancies Between Father and Adolescent Perceptions of Harsh Parenting and Conflict Associated with Adolescent Mental Health Symptoms?

Though differences in informant perceptions of family processes are associated with poorer health, few studies have examined discrepancies between father- and adolescent-report of family phenomena and their impact on adolescent mental health. This study examined how father and adolescent-reported parenting and the differences in their perceptions is related to adolescent mental health. Participants were 326 father-adolescent dyads (Fathers: Mage = 41.2; Adolescents: 7th grade students, Mage = 12.0, 48.5% female). Overall, analyses revealed significant main effects of father and/or adolescent report of father-adolescent conflict and harsh parenting on adolescent internalizing and externalizing symptoms. Analyses revealed two instances in which discrepancies between father- and adolescent-report of family phenomena was related to adolescent mental health. Given the mixed nature of the findings based on the outcome reporter, the current study discusses implications for discrepancy research and future directions to better understand discrepant perceptions as useful information on their own. The parent clinical trial is registered at ClinicalTrials.gov (Identifier: NCT03125291, Registration date: 4/13/2017).

U.S. Mexican-origin young adults' mental health relative to interpersonal stressor transitions from childhood to adolescence.

OBJECTIVES: This study sought to describe latent transitions in developmentally and culturally salient interpersonal stressors from late childhood to late adolescence and examine whether different transition patterns predicted early adult mental health problems. METHOD: Data from four waves (Grades 5, 7, 10, 12) of a study of 749 U.S. Mexican-origin youth were used for a latent transition analysis (LTA) of family, peer, and community stressors; distal outcomes of externalizing and internalizing problems were measured 5 years after Grade 12. Latent class analysis (LCA) and LTA were conducted for investigating underlying subgroups of interpersonal stress at each wave and transitions between subtypes over waves. RESULTS: For the LCA, two latent classes emerged at all four waves, representing low and high interpersonal stress. The LTA model with two classes at all waves was conducted with good fit. Six prominent transition classes emerged and related to young adult internalizing and externalizing problems. Transition class related to young adult internalizing and externalizing problems, such that youth who consistently had exposure to interpersonal stress or who had transitions from low to high exposure had more internalizing and externalizing problems. CONCLUSIONS: Findings are discussed relative to the developmental salience of these transitions and opportunities to intervene during adolescence to mitigate later mental health problems.

Infant Temperament Profiles, Cultural Orientation, and Toddler Behavioral and Physiological Regulation in Mexican-American Families.

This study sought to (a) replicate infant temperament profiles from predominantly White samples in a sample of low-income, predominantly first-generation Mexican-American families, (b) investigate associations between infant temperament profiles and toddler behavioral and physiological regulation, and (c) explore whether mothers' cultural orientation would moderate those associations. Mothers and infants (n = 322; 46% male) were assessed during pregnancy and at infant ages 9, 12, and 24 months. Latent profile analysis yielded three temperament profiles that were consistent with those from extant research. Compared to the high positive affect, well-regulated profile, the negative reactive, low regulated profile was associated with poorer behavioral and parasympathetic (i.e., respiratory sinus arrhythmia) regulation, but associations depended on mothers' Mexican and Anglo cultural orientation.

A daily diary study of sleep chronotype among Mexican-origin adolescents and parents: Implications for adolescent behavioral health.

The current study used daily assessments of sleep to examine stability and change in sleep chronotype in adolescents and their parents. The study assessed adolescent sleep chronotype according to age, gender, and parent chronotype, and evaluated its associations with emotional and behavioral problems in youth. Participants included of 417 Mexican American adolescents (Mage = 16.0 years, Range = 13.9-20.0) and 403 caregivers, who reported bed and wake times daily for 2 consecutive weeks at two time points spaced 1 year apart. In addition, adolescents completed established self-report questionnaires of emotional and behavioral problems. Chronotype was computed as the midsleep point from bed to wake time on free days, correcting for sleep debt accumulated across scheduled days. Multilevel modeling showed a curvilinear association between adolescent age and chronotype, with a peak eveningness observed between ages 16 to 17. Adolescent and parent chronotypes were contemporaneously correlated, but each was only moderately stable over the 1-year period. Later adolescent chronotype was contemporaneously associated with more substance use in all adolescents. Individual development and the family context shape sleep chronotype in adolescents and parents. Sleep chronotype is implicated in adolescent behavioral health.

Who's Influencing Who? Adolescent Symptomatology and Caregiver Mindful Parenting.

Mindful parenting is linked to positive youth emotion regulation, mental health, and parent-child relationship quality. We examined bidirectional relations between adolescent mental health and mindful parenting among a diverse sample of 249 7th grade students and their female (N = 232) and male caregivers (N = 120). We conducted multiple-group cross-lagged models (grouped by adolescent sex). Female adolescents' externalizing symptoms predicted decreased female caregiver mindful parenting six months later, but male and female adolescent externalizing behaviors were negatively associated with male caregivers' mindful parenting one year later. Findings suggest mindful parenting capacities are vulnerable to disruption via adolescent problem behavior. Mindful parenting's potential benefits, caveats, and need to support parent efforts to sustain mindful parenting amidst adolescents' externalizing behaviors are discussed.

Predictors of Caregiver Participation in an Engagement Strategy to Increase Initiation into a Family-Based Preventive Intervention.

Previous studies have shown that engagement strategies can help increase enrollment and initiation of families in evidence-based preventive programs under natural service delivery settings. However, little is known about factors that predict completion of these engagement strategies. This study aimed to examine predictors (i.e., perceived need, perceived barriers, and sociocultural context) of caregiver participation in an evidence-based engagement call strategy. This call was expected to increase initiation into a school-based, family-focused prevention program. In addition, this study examined engagement call completion as a predictor of program initiation among already enrolled families. Participants included ethnically diverse families recruited from three Title I schools (n = 413) who were randomized to receive the prevention program. Results showed that interparental conflict-an indicator of perceived need-was associated with an increased likelihood of completing the engagement call. Furthermore, caregivers from low-socioeconomic status (SES), foreign-born, Spanish-speaking, Hispanic families were more likely to complete the call relative to those from low- and mid-SES, US born, English-speaking, ethnically diverse families. Importantly, engagement call completion was associated with an increased likelihood of program initiation. These findings provide limited support that families with higher perceived needs are more likely to participate in an evidence-based engagement call strategy. Results suggested that the call strategy provides a promising way to reduce attrition from family prevention programs, which is commonly observed between enrollment and initiation.

Reducing cultural mismatch: Latino students' neuroendocrine and affective stress responses following cultural diversity and inclusion reminder.

Cultural mismatch theory suggests that a poor fit between the cultural values endorsed by individuals and the institutions to which they belong results in emotional distress and activation of physiological stress processes, particularly for underrepresented groups. To test a novel paradigm for reducing perceptions of this cultural mismatch, the current experiment evaluated whether reminding first-year Latino university students (N = 84; Mage = 18.56; SD = 0.35; 63.1% female; 85.7% Mexican descent; 65.5% first-generation college students) about institutional support for cultural diversity and inclusion would reduce neuroendocrine and affective responses to psychosocial stress. Prior to completing a modified version of the Trier Social Stress Test, participants were randomly assigned to view either a video conveying university commitment to cultural diversity and inclusion (n = 45) or a control video (n = 39) depicting a campus tour. Five saliva samples assayed for cortisol and corresponding negative affect measures were collected to assess stress reactivity and recovery patterns (pre-task baseline, post-task +30 min, +45 min, +60 min, +75 min). Repeated measures data were analyzed using bilinear spline growth models. Viewing the culture video (compared to control) significantly reduced cortisol reactivity to the TSST and post-task negative affect levels, specifically for students endorsing higher Latino cultural values (e.g., familism, respect). Post-task cortisol levels were also reduced for students endorsing higher U.S. mainstream cultural values (e.g., self-reliance, competition). Results provide novel evidence for cultural diversity in stress responsivity and individual variation in approaches to reduce perceived cultural mismatch.

Streamlined Prevention and Early Intervention for Pediatric Anxiety Disorders: A Randomized Controlled Trial.

There is a need to optimize the fit between psychosocial interventions with known efficacy and the demands of real-word service delivery settings. However, adaptation of evidence-based interventions (EBI) raises questions about whether effectiveness can be retained. This randomized controlled trial (RCT) evaluated a streamlined package of cognitive, behavior, and social skills training strategies known to prevent and reduce anxiety symptom and disorder escalation in youth. A total of 109 youth (Mage = 9.72; 68% girls; 54% Latinx) at risk based on high anxiety were randomized to the streamlined prevention and early intervention (SPEI) (n = 59) or control (n = 50) and were assessed at pretest, posttest, and 12-month follow-up. A main objective was to determine whether our redesign could be delivered by community providers, with acceptable levels of fidelity, quality, and impact. In terms of process evaluation results, there was high protocol fidelity, excellent clinical process skills, few protocol adaptations, and high satisfaction with the SPEI. In terms of outcomes, there were no significant main or moderated effects of the SPEI at the immediate posttest. However, at the follow-up, youth in the SPEI reported greater self-efficacy for managing anxiety-provoking situations, greater social skills, and fewer negative cognitive errors relative to controls. Collectively, findings suggest that the redesigned SPEI might be an attractive and efficient solution for service delivery settings.

Infections due to Cellulosimicrobium species: case report and literature review.

BACKGROUND: Cellulosimicrobium species, formely known as Oerskovia species, are gram-positive bacilli belonging to the order Actinomycetales. They rarely cause human infections. The genus comprises two pathogenic species in humans: C. cellulans and C. funkei. Based on a case report, we provide a review of the literature of infections caused by Cellulosimicrobium/Oerskovia, in order to improve our knowledge of this unusual infection. CASE PRESENTATION: An 82-year-old woman with aortic prosthetic valve presented to the hospital with fever and heart failure. Further work up revealed the diagnosis of C. cellulans infective endocarditis (IE). The strain was identified by MALDI-TOF MS, API Coryne and 16S rRNA sequencing. The patient was deemed not to be an operative candidate and died despite the antibiotic therapy 35 days after admission. CONCLUSIONS: Reviewing cases of Cellulosimicrobium species infections and communicating the successful and unsuccessful clinical experiences can assist future healthcare providers. Our case and those previously reported indicate that Cellulosimicrobium species usually infect immunocompromised patients or foreign body carriers. The most frequent pattern of infection is central venous catheter related bacteremia. The optimal treatment should include foreign body removal and valve surgery should be considered in case of IE.

Individual Differences in Optimum Sleep for Daily Mood During Adolescence.

Efforts to establish an empirical basis for recommended sleep durations during adolescence need to take into account individual differences in optimum sleep, defined as the amount of sleep at which peak functioning is observed. A total of 419 adolescents (Mage = 15.03 years) with Mexican American backgrounds reported their nightly sleep duration and daily mood for a 2-week period at 1 or 2 waves of data collection, 1 year apart. Adolescents also completed an established measure of symptomatology. Multilevel modeling revealed a nonlinear association between sleep duration and next-day mood, whereby both too little and too much sleep were associated with elevated levels of daily distress. Significant individual differences in optimum sleep were observed such that younger adolescents and those with elevated levels of internalizing and total symptomatology evidenced greater sleep durations on nights before they reported their lowest levels of daily distress. Younger adolescents and those with higher internalizing and total symptomatology may need more sleep to reach their peak functioning the next day, at least in terms of daily mood.

U.S. Mexican-origin adolescents' bicultural competence and mental health in context.

OBJECTIVES: We examined the prospective association (from Mage = 15.84 to 17.38 years) between bicultural competence and mental health among U.S. Mexican-origin adolescents relative to multiple (a) developmental niches, (b) components of bicultural competence, and (c) indicators of mental health. METHOD: Participants included 749 adolescents (49% female, 29.7% Mexico-born) recruited during late childhood and followed through late adolescence. We used latent profile analyses to identify adolescents' developmental niches based on sociocultural characteristics of the family, school, and neighborhood contexts and multiple-group structural equation modeling to examine whether these niches moderated the association between bicultural competence and mental health. RESULTS: We identified 5 distinct adolescents' developmental niches. We found no association between bicultural competence and internalizing symptoms across niches; bicultural facility predicted lower externalizing symptoms among adolescents developing in niches characterized by immigrant families and predominantly Latino schools and neighborhoods. CONCLUSIONS: The diversity found among U.S. Mexican-origin adolescents' niches underscores the need to assess context broadly by including a range of settings. Studying multiple components of bicultural competence across numerous cultural domains may provide a better understanding of any mental health benefits of biculturalism.

Emotional Coregulation in Mexican-Origin Parent-Adolescent Dyads: Associations with Adolescent Mental Health.

Research on the health benefits and consequences of close relationships has suggested the linkage in daily emotions (i.e., coregulation) between close partners is an important relationship dynamic. While the coupling of daily emotions among family members (parent-child and marital dyads) has been widely documented, research examining emotional coregulation among ethnic minority youth during adolescence, a period marked by heightened emotion and risk for psychopathology, remains an important area in need of exploration. This study examined correlates of emotional coregulation in a sample of Mexican-origin adolescents (Mage = 15.02, SD = .83) and their parents (Mage = 41.93, SD = 6.70). Dyads reported on daily levels of distress and happiness for 14 consecutive days across two waves of data collection a year apart (nwave1 = 428 dyads, nwave2 = 336 dyads). Dyads who reported getting along were more likely to coregulate their daily happiness. Importantly, coregulation of distress was only present in older adolescents who reported above average levels of internalizing symptoms. The results suggest coregulation of distress may shape or be shaped by poor mental health during the later years of adolescence, a time when youth may be establishing a degree of emotional autonomy from parents.

Adolescent Sleep Duration, Variability, and Peak Levels of Achievement and Mental Health.

To inform public health recommendations for adolescent sleep, the amounts of sleep associated with the highest levels of academic achievement and mental health were examined. The degree to which daily variability in sleep duration represents an underappreciated but functionally significant sleep behavior also was tested. A total of 421 adolescents (Mage  = 15.03 years) with Mexican-American backgrounds reported nightly sleep times for 2 weeks; approximately 80% repeated the same protocol 1 year later. Multilevel modeling indicated that the amount of sleep associated with the lowest levels of internalizing and externalizing symptoms was more than 1 hr greater than the amount associated with the highest levels of academic performance. Greater daily variability in sleep duration predicted greater symptomatology and mixed academic outcomes.

Ethnic Socialization in Neighborhood Contexts: Implications for Ethnic Attitude and Identity Development Among Mexican-Origin Adolescents.

Neighborhood Latino ethnic concentration, above and beyond or in combination with mothers' and fathers' ethnic socialization, may have beneficial implications for minority adolescents' ethnic attitude and identity development. These hypotheses, along with two competing hypotheses, were tested prospectively (from x¯age = 12.79-15.83 years) in a sample of 733 Mexican-origin adolescents. Neighborhood ethnic concentration had beneficial implications for ethnic identity processes (i.e., ethnic exploration and perceived peer discrimination) but not for ethnic attitudes. For Mexico-born adolescents, high maternal ethnic socialization compensated for living in neighborhoods low on ethnic concentration. Findings are discussed vis-à-vis the ways in which they address major gaps in the neighborhood effects literature and the ethnic and racial identity development literature.

The role of bicultural adaptation, familism, and family conflict in Mexican American adolescents' cortisol reactivity.

Scarce research has examined stress responsivity among Latino youths, and no studies have focused on the role of acculturation in shaping cortisol stress response in this population. This study assessed Mexican American adolescents' Mexican and Anglo cultural orientations and examined prospective associations between their patterns of bicultural orientation and hypothalamic-pituitary-adrenal cortisol reactivity to an adapted Trier Social Stress Test. The sample included 264 youths from a longitudinal birth cohort study who completed the Trier Social Stress Test and provided saliva samples at age 14. The youths completed assessments of cultural orientation at age 12, and family conflict and familism at age 14. Analyses testing the interactive effects of Anglo and Mexican orientation showed significant associations with cortisol responsivity, including the reactivity slope, peak levels, and recovery, but these associations were not mediated by family conflict nor familism values. Findings revealed that bicultural youth (high on both Anglo and Mexican orientations) showed an expected pattern of high cortisol responsivity, which may be adaptive in the context of a strong acute stressor, whereas individuals endorsing only high levels of Anglo orientation had a blunted cortisol response. Findings are discussed in relation to research on biculturalism and the trade-offs and potential recalibration of a contextually responsive hypothalamic-pituitary-adrenal axis for acculturating adolescents.

Intergenerational gaps in Mexican American values trajectories: Associations with parent-adolescent conflict and adolescent psychopathology.

Growth mixture modeling with a sample of 749 Mexican heritage families identified parallel trajectories of adolescents' and their mothers' heritage cultural values and parallel trajectories of adolescents' and their fathers' heritage cultural values from Grades 5 to 10. Parallel trajectory profiles were then used to test cultural gap-distress theory that predicts increased parent-adolescent conflict and adolescent psychopathology over time when adolescents become less aligned with Mexican heritage values compared to their parents. Six similar parallel profiles were identified for the mother-youth and father-youth dyads, but only one of the six was consistent with the hypothesized problem gap pattern in which adolescents' values were declining over time to become more discrepant from their parents. When compared to families in the other trajectory groups as a whole, mothers in the mother-adolescent problem gap trajectory group reported higher levels of mother-adolescent conflict in the 10th grade that accounted for subsequent increases in internalizing and externalizing symptoms assessed in 12th grade. Although the findings provided some support for cultural gap-distress predictions, they were not replicated with adolescent report of conflict nor with the father-adolescent trajectory group analyses. Exploratory pairwise comparisons between all six mother-adolescent trajectory groups revealed additional differences that qualified and extended these findings.
