Autistic children and their parents are at risk for mental health problems, but the processes driving these connections are unknown. Leveraging three data cycles (spaced M = 11.76 months, SD = 2.77) on 162 families with autistic children (aged 6-13 years), the associations between parent-child relationship quality (warmth and criticism), child mental health problems, and parent depression symptoms were examined. A complete longitudinal mediation model was conducted using structural equation modeling. Father depression mediated the link between child mental health problems and father critical comments (β = -0.017, p = 0.018; CI [-.023 - -.015]). Father report of child mental health problems mediated the association between father depression and father critical comments (β = 0.016, p = 0.040; CI [0.003-0.023]) as well as the association between father positive remarks and father depression (β = -0.009, p = 0.032; CI [-0.010 - -0.009]). Additionally, father positive remarks mediated the connection between father depression and child mental health problems (β = 0.022, p = 0.006; CI [0.019-0.034]). No mediation effects were present for mothers. Findings highlight that the mental health of parents and autistic children are intertwined. Interventions that improve the parent-child relationship may reduce the reciprocal toll of parent and child mental health problems.

The idea that some abilities might be enhanced by adversity is gaining traction. Adaptation-based approaches have uncovered a few specific abilities enhanced by particular adversity exposures. Yet, for a field to grow, we must not dig too deep, too soon. In this paper, we complement confirmatory research with principled exploration. We draw on two insights from adaptation-based research: 1) enhanced performance manifests within individuals, and 2) reduced and enhanced performance can co-occur. Although commonly assumed, relative performance differences are rarely tested. To quantify them, we need a wide variety of ability measures. However, rather than using adaptive logic to predict which abilities are enhanced or reduced, we develop statistical criteria to identify three data patterns: reduced, enhanced, and intact performance. With these criteria, we analyzed data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development to investigate how adversity shapes within-person performance across 10 abilities in a cognitive and achievement battery. Our goals are to document adversity-shaped cognitive performance patterns, identify drivers of reduced performance, identify sets of "intact" abilities, and discover new enhanced abilities. We believe principled exploration with clear criteria can help break new theoretical and empirical ground, remap old territory, and advance theory development.

One species-general life history (LH) principle posits that challenging childhood environments are coupled with a fast or faster LH strategy and associated behaviors, while secure and stable childhood environments foster behaviors conducive to a slow or slower LH strategy. This coupling between environments and LH strategies is based on the assumption that individuals' internal traits and states are independent of their external surroundings. In reality, individuals respond to external environmental conditions in alignment with their intrinsic vitality, encompassing both physical and mental states. The present study investigated attachment as an internal mental state, examining its role in mediating and moderating the association between external environmental adversity and fast LH strategies. A sample of 1169 adolescents (51% girls) from 9 countries was tracked over 10 years, starting from age 8. The results confirm both mediation and moderation and, for moderation, secure attachment nullified and insecure attachment maintained the environment-LH coupling. These findings suggest that attachment could act as an internal regulator, disrupting the contingent coupling between environmental adversity and a faster pace of life, consequently decelerating human LH.

Researchers often aim to assess whether repeated measures of an exposure are associated with repeated measures of an outcome. A question of particular interest is how associations between exposures and outcomes may differ over time. In other words, researchers may seek the best form of a temporal model. While several models are possible, researchers often consider a few key models. For example, researchers may hypothesize that an exposure measured during a sensitive period may be associated with repeated measures of the outcome over time. Alternatively, they may hypothesize that the exposure measured immediately before the current time period may be most strongly associated with the outcome at the current time. Finally, they may hypothesize that all prior exposures are important. Many analytic methods cannot compare and evaluate these alternative temporal models, perhaps because they make the restrictive assumption that the associations between exposures and outcomes remains constant over time. Instead, we provide a tutorial describing four temporal models that allow the associations between repeated measures of exposures and outcomes to vary, and showing how to test which temporal model is best supported by the data. By finding the best temporal model, developmental psychopathology researchers can find optimal windows for intervention.

Prenatal maternal anxiety is considered a risk factor for the development of child internalizing problems. However, little is known about potential mechanisms that account for these associations. The current study examined whether prenatal maternal anxiety was indirectly associated with toddler internalizing problems via prenatal maternal physiology and infant negative affectivity. We examined these associations in a longitudinal study of 162 expectant mothers from their third trimester until 18 months postpartum. Path analyses showed that higher prenatal anxiety was associated with higher infant negative affectivity at 7 months, which in turn was associated with higher toddler internalizing problems at 18 months. Prenatal anxiety was not indirectly associated with child outcomes via baseline or task-evoked respiratory sinus arrhythmia (RSA) in response to an infant cry while pregnant. However, pregnant women with greater decreases in task-evoked RSA had toddlers with greater internalizing problems, which was mediated by infant negative affectivity at 7 months. Findings suggest that prenatal anxiety and RSA reactivity to an infant cry may be independent risk factors for the development of infant negative affectivity, which in turn increases risk for toddler internalizing problems. These findings contribute to a growing literature on mechanisms that underlie intergenerational transmission of internalizing problems.

Adolescence is a period of substantial maturation in brain regions underlying Executive Functioning (EF). Adolescence is also associated with initiation and escalation of Alcohol Use (AU), and adolescent AU has been proposed to produce physiological and neurobiological events that derail healthy EF development. However, support has been mixed, which may be due to (1) failure to consider co-occurring externalizing symptoms (including other drug use) and poor social adaptation, and (2) heterogeneity and psychometric limitations in EF measures. We aimed to clarify the AU-EF association by: (1) distinguishing general externalizing symptoms from specific symptoms (AU, aggression, drug use) using bifactor modeling, (2) testing prospective associations between general externalizing symptoms and specific symptoms, and task-general EF, as indexed by a well-validated computational modeling framework (diffusion decision model), and (3) examining indirect pathways from externalizing symptoms to deficits in task-general EF through poor social adaptation. A high-risk longitudinal sample (N = 919) from the Michigan Longitudinal Study was assessed at four time-points spanning early adolescence (10-13 years) to young adulthood (22-25). Results suggested a critical role of social adaptation within peer and school contexts in promoting healthy EF. There was no evidence that specific, neurotoxic effects of alcohol or drug use derailed task-general EF development.

Childhood maltreatment (CM) deeply impacts victims' social competences. The aim of the present study was to investigate the effect that CM duration exerts on victims' affective and social development testing three different impact trajectories (i.e., linear, logarithmic and quadratic) and its physiological (facial mimicry and autonomic regulation of the heart) and behavioral (percentage of anger recognition false alarm) markers. In a cross-sectional design, 73 Sierra Leonean youths (all males, 5-17 years old) were enrolled in the study. Of those, 36 were homeless all abandoned at the age of 4 and exposed to CM, whereas 37 were controls. Only physiological markers of affective development were influenced by CM duration. A quadratic relation between the autonomic regulation recorded at rest and CM duration was found, indicating initial physiological compensation followed by progressive autonomic withdrawal. Furthermore, CM duration was associated to a specific linear decrease of facial mimicry and vagal regulation in response to angry and sad facial expressions whereas no influences were detected for happy and fearful faces. The results of the present study provide insightful clues on victims' natural patterns of resilience, deterioration, and chronicity, allowing a deeper comprehension of the developmental pathways through which early life adversities place youths on a track of lifelong health disparities.

Why is parenting in adolescence predictive of maladaptive personality in adulthood? This study sets out to investigate environmental and genetic factors underlying the association between parenting and maladaptive personality longitudinally in a large sample of twins. The present study addressed this question via a longitudinal study focused on two cohorts of twins assessed on aspects of perceived parenting (parent- and adolescent-reported) at age 14 years (n =1,094 pairs). Participants were followed to adulthood, and maladaptive personality traits were self-reported using the Personality Inventory for DSM-5 (PID-5) at age 24 or 34 years. We then modeled these data using a bivariate biometric model, decomposing parenting-maladaptive personality associations into additive genetic, shared environmental, and nonshared environmental factors. Numerous domains of adolescent-reported parenting predicted adult maladaptive personality. Further, we found evidence for substantial additive genetic (ra ranging from 0.22 to 0.55) and (to a lesser extent) nonshared environmental factors (re ranging from 0.10 to 0.15) that accounted for the association between perceived parenting reported in adolescence and adult personality. Perceived parenting in adolescence and maladaptive personality in adulthood may be related due to some of the same genetic factors contributing to both phenotypes at different developmental periods.

Social cognition is commonly altered in people with psychosis. Two main brain networks have been implicated: the default-mode network (DMN), which is associated with socio-cognitive processing, and the salience network (SN) associated with socio-affective processing. Disturbances to the resting-state functional connectivity of these networks have been identified in schizophrenia and high-risk individuals, but there have been no studies in adolescents displaying distinct trajectories of subclinical psychotic-like experiences (PLEs). To address this, the present study measured SN and DMN resting-state connectivity in a unique longitudinally followed sample of youth (n = 92) presenting with typical and atypical 4-year PLE trajectories. Compared to the typically developing low PLE control group, the atypical increasing PLE trajectory displayed reduced connectivity between the SN and DMN, increased connectivity between left and right insula, and widespread dysconnectivity from the insula and amygdala. These alterations are similar to those reported in schizophrenia and clinical high-risk samples, suggesting that early detection may be useful for mapping the developmental trajectories of psychotic disorders.

This study provides insights into the roles played by perceived stress and social support in the relationship between cumulative risk exposure (CRE) and adolescent emotional distress. Preregistered longitudinal moderated mediation analyses were used to test hypotheses relating to the association between CRE and later emotional distress; the mediating role of perceived stress in the relationship between CRE and later emotional distress; and, the moderating effects of peer and adult-level family support on the relationship between CRE and later perceived stress, among N = 19,159 adolescents over three annual waves (at ages 11/12, 12/13, 13/14). Analyses revealed that CRE significantly predicted later adolescent emotional distress. This relationship was partially mediated by perceived stress. Both peer and adult-level family support significantly moderated the impact of CRE on later perceived stress (i.e., adolescents reporting higher levels of support perceived significantly lower levels of stress resulting from CRE compared to those reporting lower levels of support). These findings provide critical empirical evidence of the roles played by perceived stress and social support in the relationship between CRE and adolescent emotional distress, with consequent implications for intervention.
