Elevated rates of exposure to multi-level chronic stressors (e.g., poverty, discrimination, acculturative stress) place low-income, Mexican-origin individuals in the United States at elevated risk for adverse psychological and physical health across the lifespan. Despite exposure to contextual risk factors, many individuals maintain positive biobehavioral health. In particular, despite greater exposure to sociodemographic risk factors, more recently immigrated Mexican-origin individuals in the U.S. may demonstrate more positive biobehavioral health, warranting consideration of specific cultural values and practices that confer and maintain positive health across generations. Parental cultural socialization is an understudied mechanism in promotive pathways of parent-child processes and child biobehavioral health. Across three generations of Mexican-origin families in the United States – maternal grandmothers, mothers, children – the current study (1) identified a multidimensional measure of child biobehavioral health across psychological and biological indicators, (2) evaluated the intergenerational transmission of grandmother-mother cultural socialization, (3) evaluated the effect of maternal cultural socialization on child-perceived parenting and child biobehavioral health, and (4) evaluated child cultural orientation as a moderator of the effect of maternal cultural socialization on child-perceived parenting and child biobehavioral health. Findings highlight the complex and nuanced relations among parental cultural socialization, individual cultural orientation, child perceptions of parenting, and child biobehavioral health among low-income, Mexican-origin families in the United States.

This study aimed to develop a measurement model for executive function (EF) in middle childhood for a low-income Mexican American sample and to elucidate dynamic change processes among measurable developmental correlates of EF during infancy and early toddlerhood as predictors of later higher-order EF abilities. Drawing from developmental theory and a model of neurovisceral integration, surges in neurocognitive regulatory abilities may be supported by both previous and concurrent changes in physiological functioning and engagement in reciprocal social relationships. Utilizing recent methodological innovations, the current study moved beyond traditional growth models to evaluate possible points of attenuation and acceleration in dyadic reciprocity and vagal functioning over time as well as dynamic associations between these unfolding developmental processes. Data were collected from 322 low-income Mexican American children in the home at 24 weeks and in a laboratory space at ages 1, 1.5, 2, 3, and 6 years. A parent-report measure of executive function also was collected over the phone between child age 7.5 and 9 years. Results suggested that, in this sample, EF was best modeled at child age 6 years as a unidimensional construct. Findings also supported the importance of earlier dyadic reciprocity for later EF, but there was a lack of evidence supporting the theorized link between EF and earlier vagal functioning and codevelopment of vagal functioning and dyadic reciprocity. This study highlights the importance of including dyadic measures of parent-child contingencies in studies of EF development and, from a clinical perspective, the potential use of relationship-based, dyadic intervention and prevention models to support crucial development of EF skills central to everyday adaptive functioning.
