  • Cross-cultural applicability of eye-tracking in assessing attention to emotional faces in preschool-aged children.

    by Sara S. Nozadi, Andrea Aguiar, Ruofei Du, Elizabeth A. Enright, Susan L. Schantz, Curtis Miller, Brandon Rennie, Mallery Quetawki, Debra MacKenzie, Johnnye L. Lewis

    Humans show an attention bias toward emotional versus neutral information, which is considered an adaptive pattern of information processing. Deviations from this pattern have been observed in children with socially withdrawn behaviors, with most research being conducted in controlled settings among children from urban areas. The goal of the current study was to examine the cross-cultural applicability of two eye-tracking-based measures in assessing attention biases and their relations to children's symptoms of socially withdrawn behaviors in two independent and diverse samples of preschool children. The cross-cultural comparison was conducted between the Navajo Birth Cohort study (NBCS), an indigenous cohort with relatively low socioeconomic status (SES), and the Illinois Kids Development study (IKIDS), a primarily Non-Hispanic White and high SES cohort. Children in both cohorts completed eye-tracking tasks with pictures of emotional faces, and mothers reported on children's symptoms of socially withdrawn behaviors. Results showed that general patterns of attention biases were mostly the same across samples, reflecting heightened attention toward emotional versus neutral faces. The differences across two samples mostly involved the magnitude of attention biases. NBCS children were slower to disengage from happy faces when these emotional faces were paired with neutral faces. Additionally, socially withdrawn children in the NBCS sample showed a pattern of attentional avoidance for emotional faces. The comparability of overall patterns of attention biases provides initial support for the cross-cultural applicability of the eye-tracking measures and demonstrates the robustness of these methods across clinical and community settings.

    “Know Your Children, Who They Are, Their Weakness, and Their Strongest Point”: A Qualitative Study on Diné Parent Experiences Accessing Autism Services for Their Children

    by Olivia J. Lindly, Davis E. Henderson, Christine B. Vining, Candi L. Running Bear, Sara S. Nozadi, Shannon Bia

    Background and Objective: Marked inequities in access to autism services and related health outcomes persist for U.S. children, undermining broader initiatives to advance the population’s health. At the intersection of culture, poverty, and ruralness little remains known about autism in many Indigenous communities. This qualitative study on the lived experiences of Navajo (Diné) parents raising a child with autism sought to identify factors affecting access to services. Methods: A Diné researcher conducted in-depth interviews with 15 Diné parents of children with autism living in or around the Navajo Nation. A directed content analysis approach was used to identify themes, subthemes, and connections between themes. Results: Twelve overarching themes emerged on Diné parents’ experiences accessing autism diagnostic and treatment services, as well as ways access to autism services can be improved. The following themes were related to diagnosis: the diagnostic process was often emotionally fraught; long wait times of up to years for diagnostic services were commonplace; limited clinician training and cultural humility impeded access to diagnostic services; and adequate health insurance, Indian Health Service referrals, care coordination, financial aid for travel, and efficient evaluation facilitated diagnosis. Themes on treatment access were as follows: parent perceptions of the extent to which an autism service helped their child affected access; social support helped parents to access treatment; obtaining referrals and care coordination influenced treatment access; treatment costs affected access; and service availability and geographic proximity impacted treatment access. Themes on ways to improve access to autism services were as follows: greater autism awareness is needed; autism-focused support groups may be helpful; and increased availability and quality of autism services across and around the Navajo Nation is paramount. Conclusions: Diné parents’ access to autism services was dynamically affected by sociocultural factors that must be addressed in future health equity-oriented initiatives.

    Effects of COVID-19 Financial and Social Hardships on Infants’ and Toddlers’ Development in the ECHO Program

    by Sara S. Nozadi, Ximin Li, Xiangrong Kong, Brandon Rennie, Deborah Kanda, Debra MacKenzie, Li Luo, Jonathan Posner, Courtney K. Blackwell, Lisa A. Croen, et al.

    Background: The financial hardships and social isolation experienced during the COVID-19 pandemic have been found to adversely affect children’s developmental outcomes. While many studies thus far have focused on school-aged children and the pandemic-related impacts on their academic skills and behavior problems, relatively less is known about pandemic hardships and associations with children’s development during their early years. Using a racially and economically diverse sample, we examined whether hardships experienced during the pandemic were associated with children’s development with a particular focus on communication and socioemotional development. Methods: Participants from eight cohorts of the Environmental influences on Child Health Outcomes program provided data on pandemic-related financial and social hardships as well as child developmental outcomes. Financial hardship was defined as at least one parent experiencing job loss or change, and social hardship was defined as families’ quarantining from household members or extended family and friends. The development of children under 4 was assessed longitudinally, before and during the pandemic (N = 684), using the Ages and Stages Questionnaire (ASQ). The Generalized Estimating Equations, which accounted for within-child correlation, were used for analysis. Results: Families from minority backgrounds and low socioeconomic status disproportionately experienced pandemic-related hardships. Male children had higher odds of experiencing negative changes in communication and personal social skills from pre- to during-pandemic visits (ORs ranged between 2.24 and 3.03 in analysis with binary ASQ outcomes and ranged from −0.34–0.36 in analyses with ASQ z-scores, ps = 0.000). Pandemic-related hardships in the social and financial areas did not explain within-individual changes in children’s developmental outcomes. Conclusion: Negative developmental changes from pre- to during-pandemic were found in boys, yet we did not find any associations between increased experience of pandemic-related hardships and children’s development. E how pandemic hardships affect development using a larger sample size and with longer follow-up is warranted.

    Prenatal Metal Exposures and Infants’ Developmental Outcomes in a Navajo Population

    by Sara S. Nozadi, Li Li, Li Luo, Debra MacKenzie, Esther Erdei, Ruofei Du, Carolyn W. Roman, Joseph Hoover, Elena O’donald, Courtney Burnette, et al.

    Early-life exposure to environmental toxicants can have detrimental effects on children’s neurodevelopment. In the current study, we employed a causal modeling framework to examine the direct effect of specific maternal prenatal exposures on infants’ neurodevelopment in the context of co-occurring metals. Maternal metal exposure and select micronutrients’ concentrations were assessed using samples collected at the time of delivery from mothers living across Navajo Nation with community exposure to metal mixtures originating from abandoned uranium mines. Infants’ development across five domains was measured at ages 10 to 13 months using the Ages and Stages Questionnaire Inventory (ASQ:I), an early developmental screener. After adjusting for effects of other confounding metals and demographic variables, prenatal exposure to lead, arsenic, antimony, barium, copper, and molybdenum predicted deficits in at least one of the ASQ:I domain scores. Strontium, tungsten, and thallium were positively associated with several aspects of infants’ development. Mothers with lower socioeconomic status (SES) had higher lead, cesium, and thallium exposures compared to mothers from high SES backgrounds. These mothers also had infants with lower scores across various developmental domains. The current study has many strengths including its focus on neurodevelopmental outcomes during infancy, an understudied developmental period, and the use of a novel analytical method to control for the effects of co-occurring metals while examining the effect of each metal on neurodevelopmental outcomes. Yet, future examination of how the effects of prenatal exposure on neurodevelopmental outcomes unfold over time while considering all potential interactions among metals and micronutrients is warranted.

  • Longitudinal patterns of anger reactivity and risk‐taking: The role of peer‐context

    by Sara S. Nozadi, Heather A. Henderson, Kathryn A. Degnan, Nathan A. Fox

    The current study examined the interplay between children's dispositional anger and susceptibility to peers' influence in increasing children's risk‐taking behaviors. Participants in the current study were children from a larger study of temperament and social–emotional development who were followed across 9, 24, 36, 48, and 60 months. Dispositional anger was measured using mothers' reports across 9 and 48 months. At 60 months, children played a risk‐taking computer game in presence of an unfamiliar peer who watched the child play. The child's risk‐taking was assessed during the game as the unfamiliar peers' reactions were coded based on comments that were peer directed, reflective of praising the target child's performance, or object directed, indicative of excitement toward the game. A latent profile analysis revealed three longitudinal anger profiles across infancy to early childhood: high stable, average stable, and low stable anger. Results suggested that as peers' object‐directed comments predicted risk‐taking independent of children's anger, the association between peer‐directed comments and risk‐taking was dependent on children's dispositional anger. Specifically, when peers praised the target child's performance, children in the high stable anger profile showed increased risk‐taking propensity. Findings are discussed based on the importance of considering both temperamental characteristics and aspects of the peer context in relation to children's risk‐taking.


  • Use of Ages and Stages Questionnaires™ (ASQ) in a Navajo population: Comparison with the U.S. normative dataset

    by Sara S. Nozadi, Li Li, Jantina Clifford, Ruofei Du, Kimberly Murphy, Lu Chen, Navajo Birth Cohort Study Team, Paula Seanez, Courtney Burnette, Debra MacKenzie, et al.

    Background: The Ages and Stages Questionnaires‐Third Edition (ASQ‐3) is a parent‐completed screening to identify young children at‐risk for developmental delays in the United States and internationally. Federal programs operating on Navajo Nation use the ASQ‐3 to determine the need for early intervention services, even though the ASQ‐3 national sample used to establish cutoff scores for referral included only 1% Native American children.Objectives: The current study aimed to compare the ASQ‐3 results from a sample of Navajo infants to those from a representative national U.S. sample and to examine the specificity and sensitivity of the ASQ‐3 in Navajo population.Methods: The sample included 530 Navajo infants (47.3% males) aged between 1 and 13 months who lived in remote and rural areas across the Navajo Nation. Children's development was assessed during home visits at 2‐, 6‐, 9‐, and 12‐month assessment windows.Results: Results showed that after 6 months, Navajo children had lower mean scores and higher percentages of children at‐risk for developmental delays than those from the national sample. The sensitivities and specificities, estimated using a Bayesian diagnostic approach under both conservative and nonconservative prior range choices, suggested a comparable validity performance to that from other ASQ‐3 studies.Discussion: The results of this study along with our ongoing comprehensive assessments at 4 years of age inform current programs working with Navajo children to improve early identification of developmental delays.


  • Longitudinal relations between behavioral inhibition and social information processing: Moderating role of maternal supportive reactions to children's emotions

    by Sara S. Nozadi, Lauren K. White, Kathryn A. Degnan, Nathan A. Fox

    Utilizing multiple measures of interpretive biases, the current study examined the roles of toddlers’ behavioral inhibition (BI) and maternal supportive reactions to children's negative emotions in relation to children's interpretive biases across middle to late childhood. Toddlers’ BI was measured during several laboratory tasks (n = 248) at 2 and 3 years of age. Mothers reported on their reactions to children's negative emotional expressions when children were 7 years old (n = 203), and children's interpretations of social cues were assessed at 7 and 10 years of age (ns = 179 and 161, respectively). Toddlers with high levels of BI expressed less positivity toward social engagement with unfamiliar peers during discussion of ambiguous social situations. Further, children with high BI were less likely to attribute the cause of negative social situations to external factors, particularly when mothers were less accepting of children's negative emotional displays. Findings are discussed in terms of cognition related to the interpretation of ambiguous and threat‐related social situations among temperamentally at‐risk children.

    The Moderating Role of Attention Biases in understanding the link between Behavioral Inhibition and Anxiety

    by Sara S. Nozadi, Sonya Troller-Renfree, Lauren K. White, Tahl Frenkel, Kathryn A. Degnan, Yair Bar-Haim, Daniel Pine, Nathan A. Fox

    The current study aimed to extend the results of White et al. (2015) by examining the moderating role of attention biases at age 5 on the relations between Behavioral Inhibition (BI) during toddlerhood and anxiety symptoms at age 10. Children's BI at 2 and 3 years of age was measured using laboratory assessments, and attention bias towards threat was assessed using a dot-probe task at age 5. Latent Class Analysis (LCA) was used to identify the probability for children's membership in an anxiety class, which reflected primary anxiety at age 10 that was not comorbid with symptoms of inattention. Maternal and self-report measures of children's mental health, collected via questionnaires and semi-structured diagnostic interviews, were used as indicators for the LCA. The results revealed that threat-related attention biases moderated the relation between BI and anxiety, such that BI positively predicted the probability of being in the anxiety class only when children had an attention bias towards threat. BI was unrelated to anxiety when children had no attention bias or an attention bias away from threat. These results indicated that attention biases during preschool may differentiate between inhibited children who are at heightened risk for anxiety later in childhood from those who are not. The results are discussed in a framework detailing the role of attention biases in increasing the sensitivity for anxiety-related problems in children who display high levels of BI during early childhood.
