Father involvement in Mexican-origin families: Preliminary development of a culturally informed measure

Infant biological sensitivity to father engagement in low-income Mexican American families

Despite a sizeable literature documenting meaningful contributions of father involvement to child health and development, researchers have paid little attention to biological characteristics that may render a child more or less sensitive to fathering behavior. The identification of child and paternal characteristics that promote child behavioral health is particularly critical in the context of sociocultural risk. We hypothesized that respiratory sinus arrhythmia (RSA) measured during infancy would moderate the impact of father engagement in caregiving activities on child behavioral health. In a sample of 181 Mexican American families, we evaluated the impact of infant RSA at 6 weeks, mother- and father-reported father engagement in caregiving activities at 15 and 21 weeks, and their interaction on toddler social or emotional behavior problems and competence at 2 years of age. Only infants with average or higher RSA exhibited more behavior problems in the context of low father engagement (p = .021). Neither RSA nor father engagement predicted behavioral competence. The results are consistent with a stress-diathesis process such that higher infant RSA increases vulnerability to suboptimal father involvement, but does not enhance the benefits of high father involvement.

Effects of maternal and paternal postnatal depressive symptoms on infants' parasympathetic regulation in low-income, Mexican American families

Mothers and fathers are at elevated risk for developing depression during the first postnatal year, especially among families from marginalized communities. Although a number of studies demonstrate that exposure to maternal depressive symptoms can undermine infants' regulatory development, less is known about the extent to which paternal depressive symptoms may also contribute. The current study investigated whether maternal and paternal depressive symptoms were uniquely associated with infants' physiological regulation, and whether associations varied depending on infant sex. Participants included 90 low-income Mexican American families. Fathers and mothers self-reported their depressive symptoms when infants were 15 weeks old, and infants' resting parasympathetic activity (i.e., respiratory sinus arrhythmia [RSA]) was assessed at 6 and 24 weeks. Results indicated that, after controlling for infant 6-week RSA and depressive symptoms in the other parent, paternal depressive symptoms were associated with lower 24-week RSA for both girls and boys, but maternal depressive symptoms were only associated with lower 24-week RSA for boys. Findings highlight a potential mechanism through which the consequences of parent depressive symptoms may reverberate across generations, and suggest that considerations of both infants' and parents' sex may lend insight into how best to intervene.

Infants' Biological Sensitivity to the Effects of Maternal Social Support: Evidence Among Mexican American Families

The identification of infants who are most susceptible to both negative and positive social environments is critical for understanding early behavioral development. This study longitudinally assessed the interactive effects of infant vagal tone (respiratory sinus arrhythmia; RSA) and maternal social support on behavioral problems and competence among 322 low-income Mexican American mother-infant dyads (infants: 54.1% female) and explored sex differences. Infant RSA was calculated from resting HR data at 6 weeks of age. Mothers reported on general social support, partner support, and family support at 6 months, and infant behavioral problems and competence at 1 year. Two-way interactions (RSA × support source) were evaluated to predict behavioral problems and competence, adjusting for covariates. Results indicated higher competence among infants with lower RSA whose mothers reported higher general support or higher partner support. Interactive effects on behavior problems of RSA with maternal partner or family support were only found for female infants: Girls with higher RSA showed more behavior problems when mothers reported low support, but fewer problem levels in the context of high support. Our results suggest that infant RSA is an important moderator of the effects of the early social environment on early development.

Culturally Adapted Behavioral Activation

The scarcity of accessible culturally competent service providers and a general sense of mistrust in Eurocentric-based mental health settings exacerbate the lack of help seeking and effective therapeutic engagement for Latinos. Thus, clinical interventions that account for diverse values and worldviews may be an important step in the helpful treatment of U.S. Latino populations. Behavioral activation (BA), an evidence-based intervention for the treatment of depression, was recently evaluated through a preliminary clinical trial study in a community clinic primarily serving Spanish-speaking Latinos, and the results were promising. A culturally adapted version of BA was developed for Latinos, which took into consideration the cultural value of familismo (a collectivist worldview and preference for maintaining close connections to family); however, BA has not been previously applied to Latino families. The current case study presents the clinical treatment of a Mexican American family living in the southwest of the United States experiencing numerous stressors resulting in depressive symptoms. Specifically, this family sought therapy having experienced many negative life events, including stressors associated with institutionalized racism, their financial situation, and acculturation process. This led to a disruption of the family hierarchy, anger, unhappiness, fear, and isolation among family members. Outcomes of the intervention include a decrease in depressive symptoms and improved family communication and relationships by their involvement in activities such as attending cultural events in their community, family outings, and the children’s participation in extracurricular activities.
