RESUMEN

The present study examined associations between sociocultural factors and self-regulation (parent-report, teacher-report, laboratory tasks), and prospective relations between self-regulation and behavioral adjustment (parent-, teacher-, child-report) in a socioeconomically diverse sample of Chinese American children in immigrant families (N = 258, Wave 1 age = 6-9 years, Wave 2 age = 9-11 years, 52% boys, 57% low-income) in a longitudinal study (2007-2011) during early elementary school years. Family income uniquely related to a self-regulation latent factor ( ß = .22), and parent-child Chinese orientation gaps were associated with parent-reported effortful control ( ß = .40). Self-regulation at W1 negatively predicted parent- and teacher-reported behavioral maladjustment ( ß s = -.22 and -.48) at W2, controlling for cross-time stability of both constructs and covariates (child sex, parental education).

RESUMEN

OBJECTIVE: Perceived racial discrimination has been associated with elevated anxiety symptoms. Less is known about the mental health implications of another race-related stressor, model minority stereotyping, which is a salient experience for Chinese-heritage youth. In addition, despite theoretical considerations and indirect empirical evidence suggesting that greater autonomic nervous system (ANS) reactivity may index sensitivity to race-related stressors, ANS reactivity has not been examined as a moderator of links between race-related stressors and mental health. The present study investigated cross-sectional associations between self-reports of two salient race-related stressors (perceived discrimination and model minority stereotyping) and anxiety symptoms in Chinese-heritage youth, as well as whether ANS reactivity moderates these relationships. METHOD: Chinese-heritage U.S. college students (N = 198, 55.6% female, 18-25 years, Mage = 20.0 years) self-reported experiences with race-related stressors. ANS reactivity (respiratory sinus arrhythmia [RSA] and pre-ejection period [PEP]) to a video depicting discrimination was collected on a subsample of participants (N = 103). RESULTS: Although both race-related stressors were positively correlated with anxiety symptoms, only perceived discrimination was uniquely associated with anxiety symptoms. Further, RSA (but not PEP) reactivity moderated the relationship between perceived discrimination and anxiety symptoms, such that associations were stronger for participants with greater RSA withdrawal. CONCLUSIONS: Our results replicate findings on the discrimination-anxiety link in Chinese-heritage college students, and show that model minority stereotyping is correlated with greater anxiety symptoms. Findings suggest that individuals with heightened RSA reactivity may be especially vulnerable to the adverse effect of discrimination. These findings have implications for mental health services for Chinese-heritage U.S. college students. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

Research Findings: Using two groups of dual language learners (DLLs), the current study examined links between two developmental constructs closely linked to school readiness: the home language environment (HLE) and executive function (EF). In a sample of 90 children (age range = 38-70 months, 59% girls) from either Mexican American (MA, N = 46) or Chinese American (CA, N = 44) low-income families enrolled in Head Start preschool programs, parents reported on their HLE (home language balance, home English/heritage language activities) and children's EF (inhibitory control and attention shifting) was measured by cognitive tasks. Findings showed preschool-aged DLLs in low-income immigrant families received more heritage language exposure relative to English language exposure at home. Several demographic variables (parental education, per capita income, DLL group, child age of English acquisition, child generation, child English receptive vocabulary) were related to various aspects of HLE. Controlling for covariates, the amount of heritage language activities at home was uniquely and positively related to children's attention shifting. Practice or Policy: The findings underscore the importance of incorporating language background considerations when designing intervention programs that target HLE and EF in low-income DLLs.

RESUMEN

Immigration patterns over the last two decades have changed the demographic composition of the United States; children are growing up in an increasingly multicultural environment. Immigrant youth may face culture-related stressors and leverage culture-related strengths across development that may influence their mental and physical health. Responses to early life stressors may differ across children at the level of stress biology, which can affect how they handle cultural challenges. However, there is limited research on culture and stress biology, which may be a mediator or moderator of culture's effects on immigrant youth. The aim of the present article is to systematically review research that examines the roles of both culture and stress biology from the prenatal period to adolescence in immigrant youth. Specifically, we review articles that examine how stress-sensitive biological systems (hypothalamic pituitary adrenal axis and the autonomic nervous system) and culture-related constructs have been modeled together in immigrant youth. Based on these findings, we note remaining questions and recommendations for future research in integrating measures of cultural processes and stress biology in children.

RESUMEN

Since the outbreak of the novel coronavirus (COVID-19) pandemic, reports of xenophobic and racist incidents directed at Chinese Americans have escalated. The present study adds further understanding to potential psychosocial effects of the COVID-19 pandemic by comparing self-reported questionnaire data from two groups of Chinese students attending a public university in western United States: the group who participated in the study before the outbreak of COVID-19 (Pre-COVID, N = 134), and the group who participated at the beginning (during-COVID, N = 64). The aim of the study was to: (a) compare mean differences in perceived discrimination and anxiety between the two groups, (b) test whether COVID-19 moderated the link between perceived discrimination and anxiety, and (c) examine whether media exposure portraying Chinese individuals negatively mediated relations between COVID-19 and discrimination. Results showed that the During-COVID group reported higher perceived discrimination and anxiety than the Pre-COVID group. The link between perceived discrimination and anxiety was stronger for the During-COVID group. Mediation analyses suggested that negative Chinese media exposure partly accounted for the group difference in perceived discrimination. Results suggest that future studies on the psychosocial implications of the COVID-19 pandemic should consider the role of discrimination in understanding the mental health of Chinese American college students.

RESUMEN

Learning to read transforms the brain, building on children's existing capacities for language and visuospatial processing. In particular, the development of print-speech convergence, or the spatial overlap of neural regions necessary for both auditory and visual language processing, is critical for literacy acquisition. Print-speech convergence is a universal signature of proficient reading, yet the antecedents of this convergence remain unknown. Here we examine the relationship between spoken language proficiency and the emergence of the print-speech network in beginning readers (ages 5-6). Results demonstrate that children's language proficiency, but not their early literacy skill, explains variance in their print-speech neural convergence in kindergarten. Furthermore, print-speech convergence in kindergarten predicts reading abilities one year later. These findings suggest that children's language ability is a core mechanism guiding the neural plasticity for learning to read, and extend theoretical perspectives on language and literacy acquisition across the lifespan.

RESUMEN

BACKGROUND: Learning disabilities (LD) and attention-deficit hyperactivity disorder (ADHD) are often accompanied by significant socio-emotional impairments and mental health challenges. However, there is a lack of controlled, quantitative research on potential interventions to address this issue. The current study evaluated the impact of a near-peer mentoring program for youth with LD/ADHD designed to promote socio-emotional well-being. METHODS: Youth with LD/ADHD who participated in the mentoring program (Mentored; n=99) were compared to non-mentored youth with LD/ADHD (Control-NM; n=51) and typically-developing youth without LD/ADHD (Control-TD; n=81) pre-mentoring in the fall, and post-mentoring in the spring. Participants were assessed on self-report measures of anxiety, depression, interpersonal relations, and self-esteem. RESULTS: Youth with LD/ADHD showed significantly higher scores of depression and significantly lower scores of interpersonal relations compared to the Control-TD group at fall baseline. The depression and self-esteem scores of the Mentored group significantly decreased and increased respectively after mentoring. These changes were associated with mentee-perceived mentorship quality. The Control-NM group showed significant decreases in both self-esteem and interpersonal relations, as well as increases in depression over time, while the Control-TD group remained stable across all measures. CONCLUSIONS: Results suggest that mentoring shows promise as a potential intervention for youth with LD/ADHD and co-occurring socio-emotional and mental health difficulties. The study is the first, to our knowledge, to quantify the effect of a near-peer mentoring program on youth with LD/ADHD in a design with two control groups. Implications for research and practice involving LD, ADHD, and mental health disorders are discussed.

RESUMEN

Extant research is increasingly recognizing the contribution of executive function (EF) to reading comprehension alongside established predictors like word decoding and oral language. The nature of the association between EF and reading comprehension is commonly investigated in older children and in those with reading impairments. However, less is known about this relationship in emerging readers in kindergarten, where word decoding and reading comprehension are highly intertwined. Moreover, a better understanding of the mechanisms by which EF influences reading comprehension is needed. The present study investigated direct contributions of EF to reading comprehension, as well as indirect contributions via word decoding in 97 kindergarteners. Results indicated that there was a significant indirect effect of EF on reading comprehension, with word decoding mediating this association. The direct contribution of EF to reading comprehension was not significant. Implications for reading instruction and intervention for early readers are discussed.

RESUMEN

Poverty detrimentally affects child executive function (EF), a subset of cognitive abilities implicated in reading and other achievement outcomes. Consequently, research has focused on understanding explanatory and mediating mechanisms in this association. This research, however, has mainly involved populations from Western, high-income countries. Children from low- and middle-income countries comprise a significant proportion of the world's population and are at additional risk for poor EF as a result of a more disadvantaged context. The present review examines global work on poverty and EF to highlight important cross-national similarities and differences. Findings suggest a global association between poverty and EF and point to cognitive stimulation and environmental enrichment as common mediating variables that may also be moderators and targets for intervention. However, findings also underscore the need to consider the sociocultural context of countries when examining impacts of parenting, schooling, and other metrics. Research and intervention implications are discussed.

RESUMEN

Exposure to stigma and stereotype threat is detrimental for numerous marginalized groups. Research has demonstrated that individuals with specific learning disabilities (SLDs) are vulnerable to stigmatization. The purpose of this systematic review was to summarize the studies investigating associations between SLD-related stigma and stereotype threat and psychological and academic outcomes in individuals with SLDs, as well as examine the overall effect size of these associations across studies. A total of 16 studies met inclusion criteria-12 studies (52 effect sizes) examined SLD stigma with psychological adjustment or academic outcomes, and six studies (eight effect sizes) examined SLD stereotype threat. Greater SLD stigma scores had a medium-sized and significant correlation with less self-esteem across nine effect sizes (r = -.39, p = .002). Other outcomes were not powered enough for meta-analyses, although studies generally showed that greater SLD stigma and stereotype threat was related to less optimal psychological adjustment. These results suggest that these negative experiences should be a target of intervention and support efforts for individuals with SLDs. The associations between SLD stigma and stereotype threat and academic performance outcomes were comparatively more heterogeneous and less robust. These findings highlight the need for more research on SLD-related stigma and stereotype threat.

RESUMEN

With the growing percentage of Chinese immigrants in the U.S. population, it is crucial to understand how pre-migration factors (such as reasons for migration) are related to the adjustment of families in the host country. The present study examined reasons for migration and their associations with post-migration sociocultural factors and parenting styles in a community-based sample of Chinese American immigrant families (N = 258) living in the San Francisco Bay Area. The parents' self-reported reasons for migration included family reasons (55.1%, e.g., family reunification), betterment reasons (18.0%, e.g., better education and occupational opportunities), and both family and betterment reasons (26.9%). Those who migrated for betterment reasons reported significantly higher parental education and per capita income than the family reason group (p < 0.001) and significantly higher income than the combined reason group (p = 0.007). No significant group differences emerged in cultural orientations and parenting styles after controlling for socioeconomic factors. The findings suggested that Chinese immigrant families who migrated solely for better education and occupational opportunities had significantly higher post-migration socioeconomic status than other reason groups. These differences have relevance for programs and services for new immigrants, as families might need different types of support (e.g., socioeconomic vs. relational) depending on their motivations for migration and post-migration socioeconomic resources.

RESUMEN

OBJECTIVE: This systematic review aims to summarize the current state of knowledge on the relations between race-related stress and trauma (RST) and emotion dysregulation, synthesize empirical research examining these associations in youth of color, and discuss clinical implications. METHOD: We searched PubMed, ProQuest PsycInfo, and Web of Science for relevant articles on June 24, 2021. Eligible studies were empirical studies in peer-reviewed journals or from gray literature. They included a sample of participants (5-24 years of age) from racial and ethnic minority backgrounds and at least 1 measure of RST and emotion dysregulation. We evaluated target studies using the Quality Assessment for Diverse Studies and extracted information on associations between RST and emotion dysregulation, as well as mediators and moderators. RESULTS: Ultimately, 29 studies (78,173 participants) met inclusion criteria. A total of 28 studies were correlational, 16 were cross-sectional, and 12 were longitudinal. Greater RST was linked to greater emotion dysregulation in 78% of observed associations. Remaining associations were not significant. Relationships were mediated by types of coping, biological factors, and identity factors. RST was also related to several wellbeing outcomes through its relations with emotion dysregulation. CONCLUSION: Results consistently demonstrated that greater exposure to RST is related to greater emotion dysregulation and decreased wellbeing in youth of color. These findings suggest that clinicians should incorporate the role of RST in case conceptualizations and treatment plans for this population. Future research should use multidimensional measures of RST and include experimental studies to examine the causal relationship between RST and emotion dysregulation.

RESUMEN

Consequences of multilingualism vary from offering cognitive benefits to poor educational and cognitive outcomes. One aspect of multilingualism that has not been systematically examined is the typology of multilinguals' languages: Do differences and similarities between languages multilinguals are exposed to contribute to the development of their cognition and brain? We investigated n = 162 5-6-year-olds with various language backgrounds on a monolingual-to-quintilingual continuum. Our results show that typological linguistic diversity can be related to expressive vocabulary knowledge in the dominant language. On neural level, it relates to brain activation patterns in (among others) the PGa area in the bilateral IPL, a brain region previously associated with multilingual experience, but never with language typology. We propose an ecologically valid way of describing the continuum of multilingual language experience and provide evidence for both the cognition and the brain of multilingual kindergartners to be related to the typological linguistic diversity of their environment.

RESUMEN

This scoping review provides an overview of previous empirical studies that used brain imaging techniques to investigate the neural correlates of emotional well-being (EWB). We compiled evidence on this topic into one accessible and usable document as a foundation for future research into the relationship between EWB and the brain. PRISMA 2020 guidelines were followed. We located relevant articles by searching five electronic databases with 95 studies meeting our inclusion criteria. We explored EWB measures, brain imaging modalities, research designs, populations studied, and approaches that are currently in use to characterize and understand EWB across the literature. Of the key concepts related to EWB, the vast majority of studies investigated positive affect and life satisfaction, followed by sense of meaning, goal pursuit, and quality of life. The majority of studies used functional MRI, followed by EEG and event-related potential-based EEG to study the neural basis of EWB (predominantly experienced affect, affective perception, reward, and emotion regulation). It is notable that positive affect and life satisfaction have been studied significantly more often than the other three aspects of EWB (i.e., sense of meaning, goal pursuit, and quality of life). Our findings suggest that future studies should investigate EWB in more diverse samples, especially in children, individuals with clinical disorders, and individuals from various geographic locations. Future directions and theoretical implications are discussed, including the need for more longitudinal studies with ecologically valid measures that incorporate multi-level approaches allowing researchers to better investigate and evaluate the relationships among behavioral, environmental, and neural factors.

RESUMEN

OBJECTIVE: Adapting mental health-care interventions to the race, ethnicity, or culture of the target group can enhance the acceptance and effectiveness of the treatment. Dialectical behavior therapy (DBT) is an evidence-based treatment that is principle-driven, rendering it well-suited for adaptations across cultural contexts. This article conducts a systematic review of the literature to determine the nature and extent of cultural adaptations of DBT to date. METHOD: We searched databases for original articles describing cultural adaptations of DBT, as applied to both (a) people of color within Western countries and (b) populations within non-Western countries. Consistent with the focus on descriptively characterizing extant DBT cultural adaptations, we included both published and nonpublished studies, as well as both observational and experimental studies. RESULTS: Our search yielded 18 articles that met inclusion criteria. Of these articles, half described adaptations made with people and communities of color within the U.S. Most adaptations involved modifications to language, metaphors, methods, and context. CONCLUSIONS: Culturally adapted DBT has been implemented and accepted among several racial, ethnic, and cultural groups, although there is insufficient evidence to determine whether culturally adapted DBT is more efficacious than nonadapted DBT. We conclude with recommendations for best practices for DBT researchers and clinicians, and situate our findings among larger efforts to render existing evidence-based psychotherapies more optimal for people of color and people from non-Western countries.

RESUMEN

Prior studies have suggested that grit and resilience predict both academic and career success. However, these qualities have not been examined in children with reading disorder (RD). We therefore investigated whether grit and resilience were associated with anxiety, depression, academic performance, and quality of life (QOL) in these students. This 3-year longitudinal cohort study included 163 participants with RD from 3 schools. Evaluations were completed by parents and/or teachers every 3 months. The Grit and Resilience Scale was adapted from the 10-item Connor-Davidson Resilience Scale and the 12-item Grit Scale. Outcome measures included anxiety (School Anxiety Scale - Teacher Report and the 8-item Spence Children's Anxiety Scale), depression (Short Mood and Feelings Questionnaire), academic performance, and QOL (Pediatric QOL Inventory 4.0). Multivariate linear regression models (adjusting for age and sex) assessed the associations at baseline. Repeated measures analysis using mixed-effects models assessed the relationship longitudinally. There were statistically significant associations between grit and resilience and all outcomes at baseline and over time. After adjusting for age and sex, improved grit and resilience was associated with decreased anxiety (ß = - 0.4, p < 0.001) and improved academic performance (ß = 0.5, p < 0.001) when grit and resilience was measured by teachers, as well as decreased depression (ß = - 0.3, p < 0.001) and improved QOL (ß = 0.6, p < 0.001) when grit and resilience was measured by parents. Grit and resilience are significantly related to mental health, academic performance, and QOL in children with RD. This suggests that interventions to improve grit and resilience may lead to positive benefits.

RESUMEN

Chronic stress during childhood negatively impacts cognition and physical and mental health. Exposure to stressors over time can cause hypothalamic-pituitary-adrenal (HPA) axis dysregulation, leading to abnormal stress hormone levels, which can be reflected in hair cortisol concentration (HCC) and hair dehydroepiandrosterone (DHEA) concentration. Although the use of HCC and DHEA to measure chronic stress in children is increasing, their effects on cognition (as indexed by executive function) remain unexplored. Accordingly, we aimed to investigate the associations of HCC, DHEA, and their ratio with measures of executive function (cognitive flexibility and working memory) in a sample of kindergarten children (N=100). We found that the expected negative association between HCC and working memory approached significance, and DHEA was significantly and positively related to cognitive flexibility. We discuss possible interpretations of our findings. Our results suggest promising areas for future investigation and encourage further exploration into HCC and DHEA as measures of chronic stress.

RESUMEN

Children with specific learning disorders (SLDs) face a unique set of socio-emotional challenges as a result of their academic difficulties. Although a higher prevalence of anxiety in children with SLD is often reported, there is currently no research on cognitive mechanisms underlying this anxiety. One way to elucidate these mechanisms is to investigate attentional bias to threatening stimuli using a dot-probe paradigm. Our study compared children ages 9-16 with SLD (n = 48) to typically-developing (TD) controls (n = 33) on their attentional biases to stimuli related to general threats, reading, and stereotypes of SLD. We found a significant threat bias away from reading-related stimuli in the SLD, but not TD group. This attentional bias was not observed with the general threat and stereotype stimuli. Further, children with SLD reported greater anxiety compared to TD children. These results suggest that children with SLD experience greater anxiety, which may partially stem from reading specifically. The finding of avoidance rather than vigilance to reading stimuli indicates the use of more top-down attentional control. This work has important implications for therapeutic approaches to anxiety in children with SLD and highlights the need for attention to socio-emotional difficulties in this population. Future research is needed to further investigate the cognitive aspects of socio-emotional difficulties in children with SLD, as well as how this may impact academic outcomes.

RESUMEN

The idea of a bilingual advantage in aspects of cognitive control-including cognitive flexibility, inhibition, working memory, and attention-is disputed. Using a sample of kindergarten children, the present study investigated associations between bilingualism and cognitive flexibility-a relationship that has shown mixed findings in prior literature. We also extend prior work by exploring relationships between bilingualism and attentional fluctuations, which represent consistency in attentional control and contribute to cognitive performance. To our knowledge, no previous study has explored this association. Theoretically, attentional fluctuations might mediate or moderate the relationship between bilingualism and cognitive flexibility. However, given evidence of null findings from extant literature when confounding variables are adequately controlled and tasks are standardized, we did not expect to find a bilingual advantage in either cognitive flexibility or attentional fluctuations. Our results supported this hypothesis when considering bilingualism both continuously and categorically. The importance of expanding upon mechanistic accounts connecting bilingualism to cognitive improvements is discussed.

RESUMEN

Reading disorder (RD), a specific learning disorder (SLD) of reading that includes impairment in word reading, reading fluency, and/or reading comprehension, is common in the general population but often is not comprehensively understood or assessed in mental health settings. In education settings, comorbid mental and associated disorders may be inadequately integrated into intervention plans. Assessment and intervention for RD may be delayed or absent in children with frequently co-occurring mental disorders not fully responding to treatment in both school and mental health settings. To address this oversight, this review summarizes current knowledge regarding RDs and common comorbid or co-occurring disorders that are important for mental health and school settings. We chose to highlight RD because it is the most common SLD, and connections to other often comorbid disorders have been more thoroughly described in the literature. Much of the literature we describe is on decoding-based RD (or developmental dyslexia) as it is the most common form of RD. In addition to risk for academic struggle and social, emotional, and behavioral problems, those with RD often show early evidence of combined or intertwined Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition childhood disorders. These include attention deficit hyperactivity disorder, anxiety and depression, disruptive, impulse-control, and conduct disorders, autism spectrum disorders, and other SLDs. The present review highlights issues and areas of controversy within these comorbidities, as well as directions for future research. An interdisciplinary, integrated approach between mental health professionals and educators can lead to comprehensive and targeted treatments encompassing both academic and mental health interventions. Such targeted treatments may contribute to improved educational and health-related outcomes in vulnerable youth. While there is a growing research literature on this association, more studies are needed of when to intervene and of the early and long-term benefits of comprehensive intervention.
