AbstractThis paper is a revised and updated edition of a previous description of the Quebec Newborn Twin Study (QNTS), an ongoing prospective longitudinal follow-up of a birth cohort of twins born between 1995 and 1998 in the greater Montreal area, Québec, Canada. The goal of QNTS is to document individual differences in the cognitive, behavioral, and social-emotional aspects of developmental health across childhood, their early genetic and environmental determinants, as well as their putative role in later social-emotional adjustment, school, health, and occupational outcomes. A total of 662 families of twins were initially assessed when the twins were aged 6 months. These twins and their family were then followed regularly. QNTS now has 16 waves of data collected or planned, including 5 in preschool. Over the last 24 years, a broad range of physiological, cognitive, behavioral, school, and health phenotypes were documented longitudinally through multi-informant and multimethod measurements. QNTS also entails extended and detailed multilevel assessments of proximal (e.g., parenting behaviors, peer relationships) and distal (e.g., family income) features of the child’s environment. QNTS children and a subset of their parents have been genotyped, allowing for the computation of a variety of polygenic scores. This detailed longitudinal information makes QNTS uniquely suited for the study of the role of the early years and gene–environment transactions in development.

The Quebec Newborn Twin Study (QNTS) is an ongoing prospective longitudinal follow-up of a birth cohort of twins born between 1995 and 1998 in the greater Montreal area, Québec, Canada. The goal of QNTS is to document individual differences in the cognitive, behavioral, and social-emotional aspects of developmental health across childhood, their early bio-social determinants, as well as their putative role in later social-emotional adjustment, school and health outcomes. A total of 662 families of twins were initially assessed when the twins were aged 6 months. These twins and their family were then followed regularly. QNTS has 14 waves of data collected or planned, including 5 in preschool. Over the past 15 years, a broad range of physiological, cognitive, behavioral, school, and health phenotypes were documented longitudinally through multi-informant and multi-method measurements. QNTS also entails extended and detailed multi-level assessments of proximal (e.g., parenting behaviors, peer relationships) and distal (e.g., family income) features of the child's environment. This detailed longitudinal information makes QNTS uniquely suited for the study of the role of the early years and gene-environment transactions in development.

(1) Background: This study examines the associations between risk behaviours and adolescent emotional and physical dating and relationship violence (DRV) victimisation and perpetration, and how these vary by gender. The risk behaviours explored include bullying, cyberbullying, sexting, alcohol, and cannabis use; (2) Methods: Cross-sectional self-report data from the School Health Research Network (SHRN) 2019 Student Health Wellbeing (SHW) survey of 48,397 students aged 11–16 from 149 schools across Wales were analysed using single and multiple-behaviour logistic regression models to explore the associations between each risk behaviour and emotional and physical DRV victimisation and perpetration; (3) Results: Bivariate analyses revealed a statistically significant association between DRV and all risk behaviours. In multivariate analyses, students who reported bullying, cyberbullying, sexting, and substance use, compared to those that had not, had significantly higher odds of experiencing and perpetrating emotional and physical DRV; and (4) Conclusions: Future studies on DRV should consider a mixed-methods approach to explore the context in which DRV and risk behaviours interrelate. Results from this study indicate the possibility that prevention and intervention programmes in school settings that seek to develop healthy school environments and peer-to-peer relationships, could inadvertently reduce the occurrence of future DRV and associated risk behaviours.

BackgroundRisk factors for alcohol problems (AP) include biological and environmental factors that are relevant across development. The pathways through which these factors are related, and how they lead to AP, are optimally considered in the context of a comprehensive developmental model.MethodUsing data from a prospectively assessed, population-based UK cohort, we constructed a structural equation model that integrated risk factors reflecting individual, family and peer/community-level constructs across childhood, adolescence and young adulthood. These variables were used to predict AP at the age of 20 years.ResultsThe final model explained over 30% of the variance in liability to age 20 years AP. Most prominent in the model was an externalizing pathway to AP, with conduct problems, sensation seeking, AP at age 17.5 years and illicit substance use acting as robust predictors. In conjunction with these individual-level risk factors, familial AP, peer relationships and low parental monitoring also predicted AP. Internalizing problems were less consistently associated with AP. Some risk factors previously identified were not associated with AP in the context of this comprehensive model.ConclusionsThe etiology of young adult AP is complex, influenced by risk factors that manifest across development. The most prominent pathway to AP is via externalizing and related behaviors. These findings underscore the importance of jointly assessing both biologically influenced and environmental risk factors for AP in a developmental context.

Previous studies show that preschool children view negative emotions as susceptible to intentional control. However, the extent of this understanding and links with child social-emotional adjustment are poorly understood. To examine this, 62 3- and 4-year-olds were presented with puppet scenarios in which characters experienced anger, sadness, and fear. Forty-seven adults were presented with a parallel questionnaire. Participants rated the degree to which six emotion-regulation strategies were effective in decreasing negative emotions. Results showed that even the youngest preschoolers viewed cognitive and behavioral distraction and repairing the situation as relatively effective; compared to adults, however, preschoolers favored relatively “ineffective” strategies such as venting and rumination. Children also showed a functional view of emotion regulation; that effective strategies depend on the emotion being regulated. All participants favored repairing a negative situation to reduce anger and behavioral distraction to reduce sadness and fear. Finally, the more children indicated that venting would reduce negative emotions, the lower their maternal report of social skills. Findings are discussed in terms of functional emotion theory and implications of emotion-regulation understanding for child adjustment.

The growth and development of toddlers is influenced by hereditary and environmental factors. Genetic factors, biologically have strong influences on toddlers’ growth in their early years of life. While psychologically, a good interpersonal relation of pregnant women with their families will make them more ready to undergo the pregnancy and childbirth. On the other hand, socially, the level of parental education might affect the nutrition intake and parenting patterns. For the economic factor, the level of family income and their ability to provide sufficient nutrition input might affect the nutritional status during gestation. The nutrition input during pregnancy highly contributes to the fetus growth and development. A poor nutrition input during gestation might cause an Intrauterine Growth Retardation (IUGR) and growth and development disorder. This study aimed to analyze the bio-psychosocial and economic factors of gestation period on toddler growth and development. This is a correlational analytic study with 80 mothers and toddlers as the sample. The data was analysed using univariat, bivariate with Chi square and multivariate with logistic regression. The results show that the statistically significant independent variables which influence the growth and development of toddlers are the mother height (p = 0.001), LILA (p = 0.008), family income (p = 0.007), infant birth weight (p = 0.009) and family support (p = 0.013). While the statistically insignificant independent variable is the mother level of education (p = 0.086).

Background. The recently enacted State Children's Health Insurance Program (SCHIP), designed to provide affordable health insurance for uninsured children, was modeled in part on New York State's Child Health Plus (CHPlus), which was implemented in 1991. All SCHIP programs involve voluntary enrollment of eligible children. Little is known about characteristics of children who enroll in these programs. Objectives. To provide a profile of children enrolled in CHPlus between 1993 and 1994 in the 6-county upstate New York study area, and to estimate the participation rate in CHPlus. Methods. A parent interview was conducted to obtain information about children, 0 to 6.9 years old, who enrolled in CHPlus in the study area. Two school-based surveys and the Current Population Survey were used to estimate health insurance coverage. Enrollment data from New York State's Department of Health, together with estimates of the uninsured, were used to estimate participation rates in CHPlus. Results. Most children enrolled in CHPlus in the study area were white. Although 17% of all children in the study area who were <13 years old and living in families with incomes below 160% of the federal poverty level were black, only 9% of CHPlus-enrolled children were black. Twenty-one percent of enrolled children were uninsured during the entire year before enrollment and 61% of children had a gap in coverage lasting >1 month. Children were generally healthy; only 4% had fair or poor health. Eighty-eight percent of parents of enrolled children had completed high school or a higher level of education. Parents reported that loss of a job was the main reason for loss of prior health insurance for their child. Most families learned about CHPlus from a friend (30%) or from their doctor (26%). The uninsured rate among children in the study area was approximately 4.1%. By 1993, the participation rate in CHPlus was about 36%. Conclusion. Blacks were underrepresented in CHPlus. Because the underlying uninsured rate was relatively low and parental education and family income were relatively high, the effects of CHPlus observed in this evaluation may be conservative in comparison to the potential effects of CHPlus for other populations of children. Participation rates during the early years of the program were modest.

The purpose of this correlational study was to investigate the relationship between peer variables (peer acceptance, peer support and peer loyalty) on young adolescents’ academic identification. The sub variables; PA, PS and PL were examined using a researcher made instrument titled  School Peer Variable Questionnaire ( α=0.86). Academic Identification was measured using the standardized Osborne (1997) Identification with Academic Scale which has (r 0.92). Sample selected was (N  = 544). Responses were scored and hypotheses tested at .05 level of significance using the PPMC. Findings revealed the importance of peer relationship on both academic and emotional adjustment of adolescent learners. Peer acceptance, support and loyalty were found to improve learners' chances of achieving positive academic outcomes.  The  implication for educators and other stakeholders in adolescent care giving and teaching is for them to understand the importance of maintaining healthy peer relationships for young learners as  teacher and peer  acceptance, peer support and peer loyalty  help them meet psychogenic needs and promote their academic motivation, self-concept, participation, classroom engagement, and feelings of belongingness in the school .Thus, findings have immense significance for educational research and practice, and also bodes well for teachers and counselors in Nigerian secondary schools. urban, ethnically

Children have many opportunities in early childhood education that support their emotions. These opportunities need to be transformed into learning situations appropriate to their development and developed. Learnings cannot happen independently of emotional intelligence. Social–emotional skills must be developed in education to achieve both academic success and success in life. It is important to support emotional intelligence in early childhood education to enable children to be emotionally healthy, to cope with difficulties, to respect differences, and to gain a social perspective by working in collaboration with others. Emotional intelligence training helps not only children but everyone in the classroom setting, especially educators who are unsure of how to work with a child with an emotional or behavioral problem. Since emotional intelligence can be developed and strengthened by training at all ages, it can be a way of teaching for educators as they regularly include methods and techniques in the program. Based on this, in this section, the emotional intelligence of children, programs methods and strategies will be discussed in terms of supporting emotional intelligence in the early years.
