Maternal Prenatal Stress and Other Developmental Risk Factors for Adolescent Depression: Spotlight on Sex Differences

Maternal stress during pregnancy has been linked to premorbid abnormalities associated with depression (e.g., difficult temperament, cognitive deficits) in offspring. However, few studies have looked across developmental periods to examine maternal stress during pregnancy and offspring depression during adolescence and whether these associations differ by sex. The current study used data from 1711 mother-offspring dyads (offspring sex: 49.8% male) in a longitudinal birth cohort study. Maternal narratives collected during pregnancy were qualitatively coded for stress-related themes by independent raters. Latent class analysis (LCA) identified distinct subgroups of offspring based on exposure to maternal prenatal stress and other developmental factors from the prenatal, childhood, and adolescent periods that have been associated with depression and/or maternal prenatal stress. LCA identified subgroups that were compared to determine whether and to what extent they differed on adolescent depressive symptoms. LCA revealed a subgroup of “high-risk” individuals, characterized by maternal factors during pregnancy (higher ambivalence/negativity and lower positivity towards the pregnancy, higher levels of hassles, lower maternal education and higher maternal age at birth, higher pre-pregnancy BMI) and offspring developmental factors (decreased cognitive functioning during childhood and adolescence, lower perceived parental support during adolescence, and higher levels of maternal depression during adolescence). High-risk females exhibited elevated conduct symptoms and higher birth order, while high-risk males exhibited decreased internalizing symptoms and lower birth order. Both high-risk males and females reported elevated depressive symptoms during adolescence relative to their “low-risk” counterparts.     

Braiding Two Evidence-Based Programs for Families At-Risk: Results of a Cluster Randomized Trial

Child maltreatment is a significant public health problem best addressed through evidence-based parent-support programs. There is a wide range of programs with different strengths offering a variety of options for families. Choosing one single evidence-based program often limits the range of services available to meet the unique needs of families. This paper presents findings from a study to examine the systematic braiding of two evidence-based programs, Parents as Teachers and SafeCare at Home (PATSCH), with the goal to provide a more robust intervention for higher risk families. A cluster randomized effectiveness trial was conducted to examine if PATSCH improved parenting behaviors known to decrease the risk for child maltreatment compared to Parents as Teachers (PAT) Alone. Parents (N?=?159; 92 PAT Alone; 67 PATSCH) were enrolled to complete a baseline, 6-month and 12-month assessment. Results indicate the groups did not differ on number of environmental hazards in the home, parents’ health care decision-making abilities, child abuse potential, and physical assault over time. However, with regard to the potential for child abuse, the PATSCH group showed a decrease in nonviolence discipline and increase in psychological aggression compared to the PAT group. Further research is needed to better examine this concept and its implications for the field.     

Engagement Agents in the Making: On the Front Lines of Socio-Technical Integration

This commentary builds on Haico te Kulve and Arie Rip’s (2011) notion of “engagement agents,” individuals that must be able to move between multiple dimensions, or “levels” of research, innovation, and policy processes. The commentary compares and contrasts the role of the engagement agent within the Constructive Technology Assessment and integration approaches, and suggests that on-site integration research represents one way to transform both social and natural scientists into competent and informed “engagement agents,” a new generation of researchers that possess the knowledge and capacities to forge “novel linkages” between the oftentimes disparate terrains of science, politics, and policy.     

Discrepancies in parents' and children's reports of child emotion regulation

The ability to regulate one’s emotions effectively has been linked with many aspects of well-being. The current study examined discrepancies between mothers’ and children’s reports of child emotion regulation. This investigation examined patterns of discrepancies for key aspects of emotion regulation (i.e., inhibition and dysregulated expression) and for three emotions (anger, sadness, worry). A total of 61 mother-child dyads (mean children’s age = 9.3 years) participated. As hypothesized, discrepancies for inhibition subscales were of a larger magnitude than those for dysregulated expression subscales. Furthermore, age was related to discrepancies in both anger subscales, parent reports of child externalizing symptoms were related to anger dysregulated expression discrepancies, and child reports of internalizing symptoms were related to sadness dysregulated expression discrepancies. Overall, the findings suggest that patterns of discrepant reports are not random but rather may provide meaningful and useful information about the nature of emotion regulation.     

Longitudinal Assessment of Sleep–Wake Regulation and Attachment Security with Parents

The development of sleep–wake regulation occurs within the context of the infant–parent relationship. The present study investigated (1) patterns of change in night waking across infancy and attachment to parents and (2) if dependency, a characteristic of secure subgroup B4 and insecure‐resistant infants, accounted for differences in night waking. Forty‐six families reported on the number of infant night wakings at 7, 12, and 14 months of age. Attachment was measured at 12 (infant–mother) and 14 (infant–father) months. Findings suggest that infants with a secure (including the dependent‐secure, B4) pattern of attachment with mothers decreased in the number of night wakings over time, whereas infants with an insecure‐resistant pattern of attachment with mothers continued to wake at night into the second year. Attachment dependency did not account for differences in night waking. These findings are important to understanding the mechanism(s) underlying the relation between attachment and sleep–wake regulation. Copyright © 2012 John Wiley & Sons, Ltd.     

Rapid development of feature binding in visual short-term memory

The binding of object identity (color) and location in visual short-term memory (VSTM) was examined in 6.5- to 12.5-month-old infants (N= 144). Although we previously found that by age 6.5 months, infants can represent both color and location in VSTM, in the present study we observed that 6.5-month-old infants could not remember trivially simple color-location combinations across a 300-ms delay. However, 7.5-month-old infants could bind color and location as effectively as 12.5-month-old infants. Control conditions confirmed that the failure of 6.5-month-old infants was not a result of perceptual or attentional limitations. This rapid development of VSTM binding between 6.5 and 7.5 months occurs during a period of rapid increase in VSTM storage capacity and just after a period of dramatic neuroanatomical changes in parietal cortex. Thus, the ability to bind features and the ability to store multiple objects may both depend on a process that is mediated by posterior parietal cortex and is perhaps related to focused attention.     

Sex-Dimorphic Color Preference in Children with Gender Identity Disorder: A Comparison to Clinical and Community Controls

The present study was designed to assess sex-dimorphic color preferences in children with gender identity disorder (47 boys, 18 girls), clinical controls (65 boys, 35 girls), and community controls (65 boys, 35 girls). The mean age of the children was 7.63 years (range?=?3–12 years). Children were shown a hexagon-shaped display of 144 colors extracted from PowerPoint?. Each child was asked to choose his or her three favorite colors (Trials 1–3) by pointing to them, naming them, and then to provide a justification for each choice. From the entire array, children labeled a total of 11 different colors: black, blue, brown, gray, green, orange, pink, purple, red, white, and yellow. For three of the colors (blue, pink/purple, and red), there was evidence for normative sex differences in color preference, and, for the colors blue and pink/purple, the gender-referred children showed inverted patterns of color preference. For the color blue, luminance values showed that the gender-referred boys and control girls preferred lighter shades, whereas the gender-referred girls and control boys preferred darker shades. Qualitative analysis indicated that gender-specific justifications were uncommon, even for the sex-dimorphic colors. Gender-referred children showed inverted gender-stereotyped color preferences, which are likely related to their more general pattern of cross-gender identification. Principles of gender-differentiated development derived from gender-schema theory are used to explain the group differences in color preferences.     

Examining Walkability and Social Capital as Indicators of Quality of Life at the Municipal and Neighborhood Scales

Walkability has been linked to quality of life in many ways. Health related benefits of physical exercise, the accessibility and access benefits of being able to walk to obtain some of your daily needs, or the mental health and social benefits of reduced isolation are a few of the many positive impacts on quality of life that can result from a walkable neighborhood. In the age of increasing energy costs and climate considerations, the ability to walk to important locations is a key component of sustainable communities. While the health and environmental implications of walkable communities are being extensively studied, the social benefits have not been investigated as broadly. Social capital is a measure of an individual’s or group’s networks, personal connections, and involvement. Like economic and human capital, social capital is considered to have important values to both individuals and communities. Through a case study approach this article argues that the generation and maintenance of social capital is another important component of quality of life that may be facilitated by living in a walkable community. Residents living in neighborhoods of varying built form and thus varying levels of walkability in three communities in New Hampshire were surveyed about their levels of social capital and travel behaviors. Comparisons between the more walkable and less walkable neighborhoods show that levels of social capital are higher in more walkable neighborhoods.
