Specialized and versatile antisocial behavioral profiles in preschoolers: Associations with persistent behavioral problems.

This study investigated specialized and versatile antisocial patterns in preschoolers and examined the link between these patterns and the risk of developing chronic antisocial behaviors throughout childhood. A total of 556 children (50.6% boys, 88% White) participated in this three-wave longitudinal study at 3-5, 6-8, and 10-12 years old.

Do you see what I see? Exploring maternal and child perceptions of children's anxiety longitudinally.

The goals of this study were to investigate (a) the dyadic relations of mothers' and children's perceptions of children's anxiety symptoms across development, (b) whether maternal perceptions of children's anxiety serve as a mediator of the association between maternal anxiety and child anxiety, and (c) whether sensitive/structured parenting moderates these processes. Participants were 180 mother-child dyads (96 female) recruited from Quebec, Canada, and assessed in preschool, middle childhood, and early adolescence. Mothers and children completed questionnaires on children's anxiety, and mothers additionally completed a questionnaire on their own anxiety.

The longitudinal effects of maternal parenting practices on children's body mass index z-scores are lagged and differential.

Background: The longitudinal relation between parenting practices and styles with children's body mass index z-scores (zBMI) is poorly understood. Previous studies suggest the relationship may be complex, but small samples and short follow-ups diminish the strength of the evidence. The objectives of this study were to investigate whether the relationship is bidirectional, time-varying, and lagged using data from a large, representative birth cohort of Quebec children.

Relationship Quality and Mental Health Implications for Adolescents during the COVID-19 Pandemic: a Longitudinal Study.

Although parent-adolescent and peer-adolescent relationship quality are critical for adolescent wellbeing during typical stressful life events, the unique features of the COVID-19 pandemic put into question whether strong parent-adolescent and peer-adolescent relationship quality functioned as protective factors of adolescent mental health in this context. The current longitudinal study examined a community sample of adolescents across 3 time points, each 6 months apart (Time 1: Fall, 2019;  = 163, 50.9% male; mean age = 15.

Associations between early poverty exposure and adolescent well-being: The role of childhood negative emotionality.

Using a longitudinal design (Wave 1 = 164, = 3.57 years, 54% female, predominantly White and French-speaking), the current study sought to answer two questions: 1) does poverty influence children's negative emotionality through heightened family-level, poverty-related stress? and 2) is negative emotionality, in turn, predictive of adolescent internalizing symptoms, externalizing behaviors, cognitive abilities, and physical health? Results confirmed an indirect pathway from family poverty to child emotionality through poverty-related stress. In addition, negative emotionality was associated with adolescent internalizing symptoms, attention difficulties, and physical health, but not externalizing symptoms, even when controlling for early poverty exposure.

Co-regulation and parenting stress over time in full-term, very low birthweight preterm, and psycho-socially at-risk infant-mother dyads: Implications for fostering the development of healthy relationships.

From birth, mothers and infants co-regulate their interactions that are shaped by their socio-emotional development, relationship history, current circumstances, and goals. However, few studies have longitudinally explored co-regulation in the context of medical and psycho-social risk. The present 4-wave longitudinal study sought to shed light on factors associated with co-regulation over time in infants from 6- to 48-months.

Conflict Resolution and Emotional Expression in Sibling and Mother-Adolescent Dyads: Within-Family and Across-Context Similarities.

Early adolescents (aged 12-15) were observed during dyadic conflict discussions with their siblings ( = 23) and mothers ( = 32) in their homes. The verbal conflict behaviors and affect of family members were coded continuously. Sequential analyses identified temporal associations between individuals' affect and their own and their partners' verbal conflict behaviors.

Promoting Postsecondary Education in Low-Income Youth: The Moderating Role of Socio-Behavioral and Academic Skills in the Context of a Major Educational Reform.

Governments around the world are pressed to invest in postsecondary education. However, little research exists to document whether large-scale educational reforms aimed at increasing rates of postsecondary attendance benefit youth's developmental outcomes. This study tested whether an educational reform occurring in Québec, Canada, in the 1960s increased educational levels, and whether it benefitted some youth more than others.

The mental health implications of COVID-19 for adolescents: Follow-up of a four-wave longitudinal study during the pandemic.

On March 11, 2020, the World Health Organization declared a pandemic due to the global outbreak of the novel coronavirus disease 2019 (COVID-19). While scientists have moved quickly to study the physical health implications of the disease, less attention has been paid to the negative mental health repercussions. The current study utilized a community sample of adolescents who had recently completed a 2-year, four wave study of adolescent mental health (Wave 1 = 184, = 13.

Conflict Resolution and Emotional Expression in Mother-Preadolescent Dyads: Longitudinal Associations with Children's Socioemotional Development.

How youth learn to manage emotions during mother-child conflict influences their socioemotional development. Ninety-four mother-preadolescent (aged 9-13, 57.4% female) dyads were observed during conflict discussions and completed questionnaire measures at one prior time-point (Time 1; ages 6-10) and one subsequent time-point (Time 3; ages 11-16) to the observations (Time 2).

Predicting psychosis-spectrum diagnoses in adulthood from social behaviors and neighborhood contexts in childhood.

Research showing that risk for schizophrenia, bipolar disorder with psychosis, and other psychosis-spectrum diagnoses in adulthood is multidetermined has underscored the necessity of studying the additive and interactive factors in childhood that precede and predict future disorders. In this study, risk for the development of psychosis-spectrum disorders was examined in a 2-generation, 30-year prospective longitudinal study of 3,905 urban families against a sociocultural backdrop of changing economic and social conditions. Peer nominations of aggression, withdrawal, and likeability and national census information on neighborhood-level socioeconomic disadvantage in childhood, as well as changes in neighborhood socioeconomic conditions over the lifespan, were examined as predictors of diagnoses of schizophrenia, bipolar disorder, and other psychosis-spectrum disorders in adulthood relative to developing only nonpsychotic disorders or no psychiatric disorders.

Maternal Emotion Socialization Mediates the Relationship between Maternal and Adolescent Negative Emotionality.

Parents and children with high negative emotionality may be more likely to provide and receive non-supportive contingencies, respectively. However, no study has examined child and parent negative emotionality in the same study and explored whether the link between child and parent negative emotionality may exist in part because of parental emotion socialization. The present study was designed to explore the link between the negative emotionality of mothers and their adolescent children and the potential mechanisms for this similarity.

Developmental patterns of change in mother and child emotional availability from infancy to the end of the preschool years: A four-wave longitudinal study.

In this four-wave longitudinal study, we examined intraindividual developmental patterns of change in mother-child emotional availability (EA) during infancy and the preschool years, the factors that promote or hinder it, and the longitudinal within-dyad association between maternal and child EA. Mother-infant dyads (N = 56) were observed at home when children were 6,12, 18 and 55-months-old. Multilevel growth modeling revealed that mother and child EA follow distinct trajectories across time.

How children's anxiety symptoms impact the functioning of the hypothalamus-pituitary-adrenal axis over time: A cross-lagged panel approach using hierarchical linear modeling.

Anxiety symptoms in childhood and adolescence can have a long-term negative impact on mental and physical health. Although studies have shown dysregulation of the hypothalamus-pituitary-adrenal axis is associated with anxiety disorders, it is unclear how and in what direction children's experiences of anxiety symptoms, which include physiological and cognitive-emotional dimensions, impact the functioning of the hypothalamus-pituitary-adrenal axis over time. We hypothesized that higher physiological symptoms would be contemporaneously associated with hypercortisolism, whereas cognitive-emotional symptoms would be more chronic, reflecting traitlike stability, and would predict hypocortisolism over time.

Neighbourhood disadvantage and behavioural problems during childhood and the risk of cardiovascular disease risk factors and events from a prospective cohort.

Both low socioeconomic status (SES) and behavioural problems in childhood are associated with cardiovascular disease (CVD) in adulthood, but their combined effects on CVD are unknown. Study objectives were to investigate the effect of neighbourhood level SES and behavioural problems during childhood on the development of CVD risk factors and events during adulthood. Participants were from a longitudinal cohort (n = 3792, baseline: 6-13 years of age) of Montreal children, followed from 1976 to 2010.

Children's anxiety symptoms and salivary immunoglobulin A: A mutual regulatory system?

Anxiety can impact the immune system resulting in negative health outcomes. Salivary immunoglobulin A (sIgA) is a first line of defense against foreign antigens, with lowered levels indicative of weakened mucosal immunity. Little is known about how anxiety symptoms affect the diurnal rhythm of sIgA secretion, or the longitudinal transactional sequence between the two in children and adolescents.

Emerging psychopathology moderates upward social mobility: The intergenerational (dis)continuity of socioeconomic status.

Socioeconomic status (SES) is relatively stable across generations, but social policies may create opportunities for upward social mobility among disadvantaged populations during periods of economic growth. With respect to expanded educational opportunities that occurred in Québec (Canada) during the 1960s, we hypothesized that children's social and academic competence would promote upward mobility, whereas aggression and social withdrawal would have the opposite effect. Out of 4,109 children attending low-SES schools in 1976-1978, a representative subsample of 503 participants were followed until midadulthood.

The impact of children's internalizing and externalizing problems on parenting: Transactional processes and reciprocal change over time.

Most theoretical models of developmental psychopathology involve a transactional, bidirectional relation between parenting and children's behavior problems. The present study utilized a cross-lagged panel, multiple interval design to model change in bidirectional relations between child and parent behavior across successive developmental periods. Two major categories of child behavior problems, internalizing and externalizing, and two aspects of parenting, positive (use of support and structure) and harsh discipline (use of physical punishment), were modeled across three time points spaced 3 years apart.

The influential child: How children affect their environment and influence their own risk and resilience.

Views regarding children's influence on their environment and their own development have undergone considerable changes over the years. Following Bell's (1968) seminal paper, the notion of children's influence and the view of socialization as a bidirectional process have gradually gained wide acceptance. However, empirical research implementing this theoretical advancement has lagged behind.

Contextual Specificity in the Relationship between Maternal Autonomy Support and Children's Socio-emotional Development: A Longitudinal Study from Preschool to Preadolescence.

The benefits of an autonomy supportive environment have been established as a key component in children's development at various ages. Nonetheless, research examining the outcomes of early autonomy supportive environments has largely neglected socio-emotional development. The first objective of the present longitudinal study was to examine the socio-emotional outcomes associated with maternal autonomy support during the preschool period.

Dispositional and Environmental Predictors of the Development of Internalizing Problems in Childhood: Testing a Multilevel Model.

This investigation evaluated a multilevel model of dispositional and environmental factors contributing to the development of internalizing problems from preschool-age to school-age. In a sample of 375 families (185 daughters, 190 sons) drawn from three independent samples, preschoolers' behavioral inhibition, cortisol and gender were examined as moderators of the links between mothers' negative parenting behavior, negative emotional characteristics, and socioeconomic status when children were 3.95 years, and their internalizing problems when they were 8.

The influence of parenting on early childhood health and health care utilization.

Objective: This study examined whether parenting, specifically parental support, structure, and behavioral control, predicted early childhood health care use and moderated the negative effects of socioeconomic disadvantage.

Methods: A sample of 250 parent-child dyads from a longitudinal intergenerational research program participated.

Results: Greater parental support was associated with increased rates of nonemergency care and a higher ratio of outpatient to emergency room (ER) services, a pattern reflecting better health and service use.

Mutual touch during mother-infant face-to-face still-face interactions: influences of interaction period and infant birth status.

Contact behaviours such as touch, have been shown to be influential channels of nonverbal communication between mothers and infants. While existing research has examined the communicative roles of maternal or infant touch in isolation, mutual touch, whereby touching behaviours occur simultaneously between mothers and their infants, has yet to be examined. The present study was designed to investigate mutual touch during face-to-face interactions between mothers and their 5½-month-old fullterm (n=40), very low birth weight/preterm (VLBW/preterm; n=40) infants, and infants at psychosocial risk (n=41).

Depressogenic thinking and shame proneness in the development of internalizing problems.

This study examined depressogenic thinking and shame proneness as factors in the development of internalizing problems in a longitudinal sample of 174 children (99 boys, 75 girls). At 7.6-9.

Longitudinal associations between infections and atopic disorders across childhood and dysregulated adrenocortical functioning in early adolescence.

The present study sought to determine if exposure to common childhood medical problems (i.e., infections and atopic disorders [e.
