Child temperament and trajectories of student-teacher relationships quality.

This study aimed to examine the associations between child temperament and trajectories of the three dimensions of the student-teacher relationship (Closeness, Conflict, and Dependency) during elementary school. Latent class growth analyses conducted among 744 French-Canadian students recruited between 2008 and 2010 (46.8% girls; Mage = 8.39; 90.9% White; 49.7% with externalizing behavior problems) revealed four Closeness trajectories and three Conflict trajectories, but no significant variability between children in mean levels of change in Dependency. Surgency-Extraversion and Effortful control were associated with specific trajectories of Closeness and Conflict. Effortful control was also associated with cross-sectional assessments of Dependency. These results suggest that temperament is a useful construct in understanding developmental patterns of the student-teacher relationship across the elementary school years.

Associations between externalizing behavior problems and risky sexual behaviors in adolescence: Attachment as a mediator.

INTRODUCTION: Risky sexual behaviors in adolescence are associated with negative health and psychological functioning outcomes. Although the association between behavior problems and risky sexual behaviors is well established, addressing these problems requires understanding the mechanisms that help explain this association. Adolescent attachment, while related to risky sexual behavior, has not been extensively explored as an outcome of childhood externalizing problems. The two objectives of this study were to explore the links between parental and peer attachment and risky sexual behaviors and to examine the mediating effect of attachment on the links between behavior problems and risky sexual behaviors. METHODS: Five hundred and ninety-eight French-Canadian adolescents (46.2% girls), Mage at T1 = 13.23; Mage at T2 = 14.28; Mage at T3 = 17.35) participated in this longitudinal study. RESULTS: The quality of parental attachment at T2 was significantly and negatively associated with risky sexual behaviors 3 years later, at T3. More specifically, a lower quality parental attachment relationship was associated with having nonexclusive partners as well as with inconsistent condom use. Finally, parental attachment (T2) was a significant mediator between behavior problems (T1) and risky sexual behaviors (T3), but only for younger adolescents. CONCLUSIONS: Findings suggest that in addition to behavior problems in adolescence, the quality of parental attachment relationships may help in understanding risky sexual behaviors in adolescence.

A longitudinal study of child adjustment during the COVID-19 pandemic: the protective role of the parent-child relationship in middle childhood.

This longitudinal study assessed how parent-child relationship quality during the first COVID-19 lockdown was related to changes in internalizing, externalizing, and sleep problems during the first months of the pandemic: during lockdown, partial deconfinement, and total deconfinement. Participants included 167 children (9-12 year) and their parents recruited in the province of Quebec, Canada. Child behavior problems decreased between lockdown and the two deconfinement assessments, but more sleep and behavior problems were associated with lower levels of relationship quality (more conflict, less closeness, and more insecure attachment). Significant interaction effects showed that changes in externalizing and sleep problems varied as a function of parent-child relationship. Results support the critical importance of the parent-child relationship with regard to child adjustment in middle childhood in times of crisis such as a pandemic. They also highlight resilience in children aged 9 to 12, with a decrease in problems over time.

Early childhood attachment stability to mothers, fathers, and both parents as a network: associations with parents' well-being, marital relationship, and child behavior problems.

This study examines the stability of child attachment to mothers and fathers separately, and to both parents as a network between the infancy and preschool periods using a sample of 143 biparental families and their children (73 boys) recruited from the general population. Attachment was assessed at 15 months with the Strange Situation Procedure (SSP) and at 45 months with the Preschool Attachment Classification Coding System (PACS). First, results show no stability in attachment to mothers, to fathers, or to both parents as a network. Second, parents' mental health, life satisfaction, marital satisfaction, and child externalizing behavior are associated with attachment stability. Taken altogether, group comparisons reveal that children with a stable secure attachment to both parents as a network have parents with higher levels of well-being and exhibit less problem behaviors than children with 1) a stable secure attachment to one parent and an unstable attachment to the other parent (from secure to insecure or from insecure to secure), or 2) who never had a stable secure attachment to either parent. This study highlights the significance of attachment to both parents as a network over time as it is associated with developmental outcomes.

An examination of the relationship between conduct problems and depressive symptoms comorbidity and temperament among elementary school children.

Although the comorbidity between conduct problems (CP) and depressive symptoms (DS) is associated with a host of negative outcomes, the factors, such as temperament, that might explain this comorbidity in school-aged boys and girls are poorly understood. This study compared elementary school children presenting co-occurring CP and DS to children with DS only, CP only, and those with low-level symptoms on temperament dimensions, and explored the moderating role of child sex in the associations. Participants are 487 children (M = 8.38 years, SD = 0.92, 52.2% girls) divided into four groups (CP + DS, DS only, CP only, control). Findings suggest that boys with CP and DS presented a lower level of fear than boys with DS and boys from the control group. They also presented higher levels of activity than boys with DS. Girls with CP and DS presented lower levels of fear than girls with DS, lower levels of approach and activity than girls with CP, and higher levels of shyness than girls from the control group. These findings suggest that temperament may discriminate children with comorbid CP and DS from those presenting only CP or DS.

Exploring childhood temperament as a moderator of the association between adolescent sexual minority status and internalizing and externalizing behavior problems.

INTRODUCTION: Sexual minority youth experience worse mental health compared to their heterosexual peers, reflecting the consequences of sexual minority-based stigma. Previous research has focused on contextual variation to understand variability within this vulnerability. Childhood temperament factors such as negative affect, effortful control and surgency/extraversion are important for understanding differential susceptibility to environmental stressors. The objective of the current study was to understand how childhood temperament factors, measured prior to the most difficult developmental period for sexual minority youth, moderated the association between sexual minority status and internalizing and externalizing behavior problems. METHODS: Youth reporting same-sex attraction in an ongoing longitudinal project on the development of conduct problems in Quebec, Canada were matched with heterosexual peers, for an analytic sample of 280 youth (62% girls). Structural equation models were used to examine (1) the association between youth-reported same-sex attraction (ages 13-16) and parent and youth-reported internalizing and externalizing problems a year later at ages 14-17, and (2) the moderating role of temperament (ages 6-9) in this association between sexual minority status and internalizing and externalizing problems. RESULTS: Same-sex attraction was associated with higher levels of youth-reported internalizing and externalizing behavior problems. Surgency/extraversion moderated the association between sexual minority status and youth-reported internalizing and externalizing problems. CONCLUSIONS: These findings suggest that temperament linked to individual visibility may be important for understanding variation in self-reported mental health among sexual minority youth, and supports the use of developmental constructs like temperament to better understand vulnerability to psychosocial difficulties within this population.

Trajectories of Verbal and Physical Peer Victimization Among Children with Comorbid Oppositional Defiant Problems, Conduct Problems and Hyperactive-Attention Problems.

The high levels of comorbidity between oppositional/conduct problems and hyperactivity/attention problems underscore the need for assessing how vulnerability for peer victimization is shaped by overlap among these behavior problems. Children (mean age 8.39, SD = 0.93) participating in a longitudinal study of the development of conduct problems (N = 744; 348 girls) in Quebec, Canada, were evaluated by their teachers regarding experiences of peer verbal and physical victimization every year for 6 years. Parent and teacher ratings of clinically significant oppositional/conduct problems, and hyperactivity/attention problems, as well as cormorbid opposition defiant/conduct problems and hyperactivity/attention problems were regressed onto trajectories of verbal and physical victimization. While behavior problems (both alone and together) were associated with higher levels of verbal and physical victimization, some variation was observed across rater and type of victimization. Ultimately, these findings suggest the importance of adapting programming for reducing victimization to children with oppositional and conduct problems.

Intrinsic Motivation and Achievement in Mathematics in Elementary School: A Longitudinal Investigation of Their Association.

This study examined the associations between intrinsic motivation and achievement in mathematics in a sample of 1,478 Canadian school-age children followed from Grades 1 to 4 (ages 7-10). Children self-reported their intrinsic motivation toward mathematics, whereas achievement was measured through direct assessment of mathematics abilities. Cross-lagged models showed that achievement predicted intrinsic motivation from Grades 1 to 2, and from Grades 2 to 4. However, intrinsic motivation did not predict achievement at any time. This developmental pattern of association was gender invariant. Contrary to the hypothesis that motivation and achievement are reciprocally associated over time, our results point to a directional association from prior achievement to subsequent intrinsic motivation. Results are discussed in light of their theoretical and practical implications.

Precocious Initiation into Smoking, Alcohol Use, and Gambling among Children with Conduct Problems.

OBJECTIVE: Adolescent participation in risky and addictive behaviours, such as smoking, substance use, and gambling has the potential to lead to many serious problems. The presence of conduct problems (CPs) and early initiation into risky and addictive behaviours have been independently shown to be associated with adolescent and young adult smoking, drinking, and gambling. Nevertheless, the relation between early initiation into risky and addictive behaviours and CPs remains to be explored among pre-adolescents. Our study aims to examine the prospective relation between CPs in early primary school and pre-adolescent initiation into smoking, alcohol use, and gambling. METHOD: Our study used data from participants in an ongoing prospective, longitudinal study at the Université de Sherbrooke to examine cigarette, alcohol, and gambling initiation among primary school-aged boys and girls with CPs. Children were recruited between the ages of 6 and 9 years from several low socioeconomic status public schools in diverse geographical regions of Quebec. Initiation into cigarettes, alcohol, and gambling was measured 1 year later. RESULTS: Children with CPs were found to be at greater risk for early initiation into smoking, alcohol, and gambling. These effects remained even once other known risk factors, such as poor parental supervision and child effortful control, were controlled for. CONCLUSIONS: These results suggest that CPs present in early elementary school can predict early initiation in to potentially addictive behaviours among boys and girls. Implications for targeted preventive intervention are discussed.

Longitudinal associations between conduct problems and depressive symptoms among girls and boys with early conduct problems.

Youth with conduct problems (CP) may experience high rates of depressive symptoms (DS). However, little is known about the direction of the longitudinal associations between CP and DS in this specific population. Although girls with CP appear at greater risk than boys for presenting comorbid depression, empirical research on gender differences in these associations is even sparser. The current study used autoregressive latent trajectory models to compare four perspectives with hypotheses regarding the longitudinal associations between CP and DS, while taking into account the evolution of both problems. We also examined gender differences in the longitudinal associations. A total of 345 children (40.6 % female) presenting with a high level of CP in early elementary school (mean age at study inception = 8.52; SD = .94) were evaluated annually over a four-year period (5 measurement time points). The results revealed that CP and DS were quite stable over time. Moreover, CP and DS showed strong covariation at each measurement time point, but only one significant positive cross-lagged association between the two processes, indicating that higher levels of DS at time 3 were associated with higher levels of CP 1 year later. No differences were observed in the longitudinal associations between CP and DS in boys and girls. Given the comorbidity and stability of CP and DS, these findings suggest that DS should be systematically evaluated among children with early clinically significant CP, and treatment plans should include interventions aimed at both CP and DS among children who present with both types of problems.

Cross-cultural investigation into cognitive underpinnings of individual differences in early arithmetic.

The present study evaluated 626 5-7-year-old children in the UK, China, Russia, and Kyrgyzstan on a cognitive test battery measuring: (1) general skills; (2) non-symbolic number sense; (3) symbolic number understanding; (4) simple arithmetic - operating with numbers; and (5) familiarity with numbers. Although most inter-population differences were small, 13% of the variance in arithmetic skills could be explained by the sample, replicating the pattern, previously found with older children in PISA. Furthermore, the same cognitive skills were related to early arithmetic in these diverse populations. Only understanding of symbolic number explained variation in mathematical performance in all samples. We discuss the results in terms of potential influences of socio-demographic, linguistic and genetic factors on individual differences in mathematics.

Why children differ in motivation to learn: Insights from over 13,000 twins from 6 countries.

Little is known about why people differ in their levels of academic motivation. This study explored the etiology of individual differences in enjoyment and self-perceived ability for several school subjects in nearly 13,000 twins aged 9-16 from 6 countries. The results showed a striking consistency across ages, school subjects, and cultures. Contrary to common belief, enjoyment of learning and children's perceptions of their competence were no less heritable than cognitive ability. Genetic factors explained approximately 40% of the variance and all of the observed twins' similarity in academic motivation. Shared environmental factors, such as home or classroom, did not contribute to the twin's similarity in academic motivation. Environmental influences stemmed entirely from individual specific experiences.

The Russian School Twin Registry (RSTR): project PROGRESS.

The Russian School Twin Registry (RSTR) was established in 2012, supported by a grant from the Government of the Russian Federation. The main aim of the registry is to contribute to Progress in Education through Gene-Environment Studies (PROGRESS). The formation of the registry is ongoing and it is expected that most schools in the Russian Federation (approximately 50,000 schools) will contribute data to the registry. With a total of 13.7 million students in Grades 1-11 (ages 7-18), the potential number of twin pairs exceeds 100,000. Apart from the large sample size and its representative nature, the RSTR has one unique feature: in collaboration with the International Advisory Committee to the Registry, genetically sensitive cross-cultural investigations are planned, aided by the use of the common assessment instruments. Other strengths of the registry include the assessment of a large sample of non-twin school children, including those studying in the same classes as the twins in the registry. It is hoped that the RSTR will provide an important research platform for national and international educationally relevant research.

Mother-infant interaction context matters for verbal and non-verbal parental mentalization: an initial portrait of associations between parental embodied mentalizing, mind-mindedness, and maternal characteristics in a structured and unstructured context.

Introduction: Interest in studying the parental embodied mentalizing (PEM), which refers to implicit and non-verbal processes of parental mentalization, is relatively recent. Therefore, little is known about how PEM, in complementarity with the verbal parental mentalization, is associated with maternal characteristics regarding mother-infant interaction contexts. This exploratory study aimed to investigate the associations between the non-verbal and verbal dimensions of parental mentalization- PEM and mind-mindedness, respectively, - in relation to a wide spectrum of parental characteristics in different interactive mother-infant contexts (toys and no toys). Methods: Among a sample of 107 mother-infant dyads at moderate psychosocial risk, mothers' sociodemographic information (age, education, and income), psychological characteristics (depression and anxiety), cognitions (self-efficacy and perceived maternal impact), and attitudes (overprotection and parental warmth) were assessed via self-report questionnaires when the infant was 4 and 8 months old. The PEM and mind-mindedness were evaluated through observation made during a videorecorded sequence of mother-infant interaction in a context of free play with and without toys at 8 months of age. Results: The results showed distinct associations between PEM and mind-mindedness regarding maternal characteristics: PEM was associated with the mother's age, education, anxiety and maternal warmth, whereas mind-mindedness was related to cognitions. Both were linked to family income. Regarding mother-infant interaction contexts (toys vs. no toys), the results indicate that the capacity to verbally and non-verbally mentalize differs. Discussion: These findings shed light on distinctive associations between non-verbal and verbal parental mentalization in relation to certain maternal characteristics, and highlight that the mother-infant interaction context may play an important role in the expression of maternal mentalizing capacity.

Prenatal maternal stress during the COVID-19 pandemic and birth outcomes: Is the newborn spared?

The COVID-19 pandemic has generated numerous stressors among the general population, but more specifically in pregnant women because of disruptions in prenatal care and delivery conditions. Studies suggest that prenatal maternal stress increased during the pandemic (Berthelot et al., 2020; Perzow et al., 2021; Tomfohr-Madsen et al., 2021). Considering what is known about the fetal programming potential of prenatal maternal stress, several researchers, early in the pandemic, raised concerns over the significant negative consequences that the pandemic context could have on birth outcomes. Studies comparing birth outcomes during versus before the pandemic suggest a marginal increase in birthweight and a significant decrease in preterm birth (Yang et al., 2022), but individual variations in prenatal maternal stress during the pandemic have received less attention. The objective of the present study is to examine the association between prenatal maternal stress during the COVID-19 pandemic and birth outcomes. During pregnancy, 195 expecting mothers reported on their general and pandemic-related stress. When their child was 6 months old, mothers completed a questionnaire collecting information on birth outcomes (gestational age, birthweight, head circumference and Apgar scores). Hierarchical linear regressions show that none of the maternal prenatal stress variables significantly predicted variations in birth outcomes. Potential pandemic-related protective factors (e.g., changes in life and hygiene habits, rest imposed by lockdowns) and the need to offer support to pregnant women are discussed.

Student-teacher relationship quality moderates longitudinal associations between child temperament and behavior problems.

Relatively few studies have focused on relational factors within the school environment that could moderate the associations between temperament and behavior problems. The purpose of this longitudinal study was to examine whether student-teacher relationship quality (i.e., Closeness, Conflict, and Dependency) moderated longitudinal associations between child temperament (i.e., Negative Affectivity, Surgency/Extraversion, and Effortful Control) and externalizing and internalizing problems. The participants were 744 elementary school students (mean age 8.4 years at study entry) followed over 3 years (four measurement times). Parents assessed their child's temperament at study entry (T1) and the children reported their self-perceptions of problems 3 years later (T4). Student-teacher relationship quality was constructed as a latent variable based on ratings from three different teachers over 3 years (T1, T2, T3). Latent moderated structural equations revealed that a low level of Surgency/Extraversion was associated with less internalizing problems but only for children experiencing a high level of Closeness with their teachers. A high level of Negative Affectivity was associated with more internalizing problems, but only for children experiencing a high level of Conflict or a high level of Dependency with their teachers. Student-teacher relationship quality did not moderate the associations between temperament and externalizing problems. Improving student-teacher relationship quality through focused interventions thus represents a useful strategy.

Maternal Functioning and Child's Externalizing Problems: Temperament and Sex-Based Driven Effects.

This study examines how maternal adverse parenting (hostility, neglect, low warmth) and psychological distress explain the associations between child temperament factors and externalizing problems. It also examines if these associations differ according to the child's biological sex. The sample consists of 339 school-age children receiving in-school services for conduct problems. Data were collected through questionnaires completed by mothers at 3 time points, at one-year intervals. Results from path analyses revealed that maternal psychological distress partly explained the associations between each child temperamental factors (negative affectivity, surgency/extraversion, effortful control) and levels of externalizing problems. Specifically, the indirect effect of psychological distress between child negative affectivity and externalizing problems was only significant for boys, not girls. Maternal hostility, on the other hand, mediated the association between child surgency/extraversion and externalizing problems in both boys and girls. Interestingly, neglectful parenting and maternal warmth did not explain the association between child temperamental factors and externalizing problems. The findings suggest small but significant temperament child-driven effects on maternal psychological distress and hostility, in turn, translating into higher levels of externalizing problems. These findings support the relevance of temperament-based interventions for children with conduct problems and of increased mental health support for their mothers. By aiding mothers in developing a larger repertoire of parenting strategies, mothers may be better equipped to respond appropriately to their child's various temperamental characteristics, hence, reducing their psychological distress and hostile behaviors and limiting the development of child externalizing problems.

Is the Association Between Early Childhood Screen Media Use and Effortful Control Bidirectional? A Prospective Study During the COVID-19 Pandemic.

Individual differences in effortful control, a component of temperament, reflecting the ability to use attention and other cognitive processes to self-regulate emotion and behavior, contribute to child academic adjustment, social competence, and wellbeing. Research has linked excessive screen time in early childhood to reduced self-regulation ability. Furthermore, research suggests that parents are more likely to use screens with children who have more challenging temperaments, such as low levels of effortful control. Since screen time by children between the ages of 0 and 18 has increased during the COVID-19 pandemic, it remains timely to investigate the developmental pattern of association between child screen media use and effortful control. We hypothesize that higher levels of screen media intake at age 3.5 will be associated with lower effortful control at age 4.5 and that lower effortful control at 3.5 will contribute to more screen media intake at age 4.5. This study draws on participants followed longitudinally over the span of 2-years for an investigation of Canadian preschoolers' screen media use during the pandemic (N = 316, Wave 1). A follow-up with this sample was completed in 2021 (N = 265, Wave 2). Analyses using a cross-lagged panel model revealed stability in child screen time and effortful control between the ages of 3.5 and 4.5. Child screen time at age 3.5 significantly contributed to decreased effortful control scores at the age of 4.5, whereas effortful control at age 3.5 did not contribute to screen time at age 4.5. Our results partially confirmed our hypothesis and indicated that higher levels of screen time intake were detrimental to the development of effortful control. These results suggest that screen media use, an exceedingly frequent activity, may play an enduring role in development by shaping young children's temperaments.

From Negative Emotionality to Aggressive Behavior: Maternal and Paternal Parenting Stress as Intervening Factors.

Child temperament plays a key role in the development of psychopathology, notably through transactions with the family environment. In particular, temperamental negative emotionality is a documented antecedent of child aggressive behavior, with parenting stress sometimes proposed to play a mediating role in this association. However, research has mostly addressed bivariate associations and seldom considered the full chain linking child negative emotionality to aggression through parenting stress. In addition, most relevant studies have focused on mothers; therefore, possible combined contributions of maternal and paternal stress, such as interactive effects, are under-investigated. Addressing these gaps, this longitudinal multi-informant study aimed to examine the mediating role of maternal parenting stress, paternal parenting stress, and their interaction in the association between infant negative emotionality and child aggression. Among 186 mostly White middle-class families (98 boys), infant negative emotionality was reported by mothers and fathers at 15 months, both parents reported on their own parenting stress at 3 years, and child aggression was assessed by teachers in the first grade of elementary school. The results revealed a moderated mediated pathway, such that there was a significant indirect effect of child negative emotionality on aggression through paternal stress, however only when maternal stress was also high. These findings suggest that the risk of negative emotionality translating to aggressive behavior is magnified when both parents experience high levels of stress in their parenting role. The results also underscore that both parents play significant yet different roles in the process linking early negative emotionality to subsequent aggression.
