12. Early Childhood Education and Later Educational Attainment and Socioeconomic Wellbeing Outcomes to Age 30

Author

McLeod, Geraldine F. H., Horwood, L. John, Boden, Joseph M., and Fergusson, David M.

Abstract

This paper examines the associations between attendance at early childhood education (ECE) and longer-term academic attainment and socioeconomic wellbeing in a New Zealand birth cohort studied to age 30. Nearly 95% of the cohort had attended ECE by age 5. After adjustment for family background and child characteristics, results showed statistically significant trends for increasing duration of ECE attendance to be associated with: greater attainment of high school and university qualifications and higher adult socioeconomic wellbeing (income, employment, occupational status); effect size estimates were small to moderate. No evidence was found for differential effects of ECE attendance across subgroups defined by child: ethnicity, gender, parental education or socioeconomic status. The implications of these findings are discussed.

Abstract

DUF1220 protein domains exhibit the greatest human lineage-specific copy number expansion of any protein-coding sequence in the genome, and variation in DUF1220 copy number has been linked to both brain size in humans and brain evolution among primates. Given these findings, we examined associations between DUF1220 subtypes CON1 and CON2 and cognitive aptitude. We identified a linear association between CON2 copy number and cognitive function in two independent populations of European descent. In North American males, an increase in CON2 copy number corresponded with an increase in WISC IQ (R (2) = 0.13, p = 0.02), which may be driven by males aged 6-11 (R (2) = 0.42, p = 0.003). We utilized ddPCR in a subset as a confirmatory measurement. This group had 26-33 copies of CON2 with a mean of 29, and each copy increase of CON2 was associated with a 3.3-point increase in WISC IQ (R (2) = 0.22, p = 0.045). In individuals from New Zealand, an increase in CON2 copy number was associated with an increase in math aptitude ability (R (2) = 0.10 p = 0.018). These were not confounded by brain size. To our knowledge, this is the first study to report a replicated association between copy number of a gene coding sequence and cognitive aptitude. Remarkably, dosage variations involving DUF1220 sequences have now been linked to human brain expansion, autism severity and cognitive aptitude, suggesting that such processes may be genetically and mechanistically inter-related. The findings presented here warrant expanded investigations in larger, well-characterized cohorts.

31. Bullying in Childhood, Externalizing Behaviors, and Adult Offending: Evidence from a 30-Year Study

Author

Fergusson, David M., Boden, Joseph M., and Horwood, L. John

Abstract

This study examined the developmental processes linking childhood bullying to criminal offending in adulthood, using data from a 30-year longitudinal study. The linkages between bullying in childhood and three criminal offending outcomes in adulthood were estimated both before and after control for a range of confounding factors. A series of protective factors that potentially mediated these linkages were also examined. The results of the study showed that while the majority of the association between childhood bullying and adult offending could be explained by confounding factors including childhood externalizing behavior, there was evidence for direct linkages from bullying to violent offending and arrest/conviction. There was little evidence to suggest mediation of the associations. The results suggest that bullying prevention requires interventions aimed specifically at bullying behavior.

32. Quality of Parent-Child Relations in Adolescence and Later Adult Parenting Outcomes

Author

Friesen, Myron D., Woodward, Lianne J., Horwood, L. John, and Fergusson, David M.

Abstract

Data from the Christchurch Health and Development Study, a 30-year prospective longitudinal study, were used to examine the associations between the quality of parent-child relations in adolescence and adult parenting behaviour 15 years later. At ages 14 and 15 years, cohort members were interviewed about the quality of their relationship with their parents. At age 30, those who had become parents underwent a parenting assessment using self-report and observational ratings of positive (warmth, sensitivity) and negative parenting (overreactive, inconsistency, and physical punishment/abuse). Results showed that adolescents who reported higher quality parent-child relationships were later characterized by higher levels of parental warmth, sensitivity, and effective child management, and lower levels of overreactive parenting. These associations remained after extensive covariate adjustment. Study findings highlight the importance of close parent-child relations during adolescence in preparing an individual for the challenges of caring for and parenting their own children when they themselves become parents.

33. The Quality of Parent/Child Relationships in Adolescence Is Associated with Poor Adult Psychosocial Adjustment

Author

Raudino, Alessandra, Fergusson, David M., and Horwood, L. John

Abstract

This study used data gathered over the course of a New Zealand longitudinal study (N = 924) to examine the relationships between measures of parental bonding and attachment in adolescence (age 15-16) and later personal adjustment (major depression; anxiety disorder; suicidal behaviour; illicit drug abuse/dependence; crime) assessed up to the age of 30. Key findings included: 1) There were significant (p less than 0.05) and pervasive associations between all measures of attachment and bonding and later outcomes. 2) Structural equation modelling showed that all measures of bonding and attachment loaded on a common factor reflecting the quality of parent/child relationships in adolescence. 3) After adjustment for covariates there were modest relationships ([beta] = 0.16-0.17) between the quality of parent/child relationships in adolescence factor and later adjustment. The study findings suggest that the quality of parent/child relationships in adolescence is modestly related to later psychosocial functioning in adulthood. (Contains 2 tables and 1 figure.)

34. Childhood Anxiety/Withdrawal, Adolescent Parent-Child Attachment and Later Risk of Depression and Anxiety Disorder

Author

Jakobsen, Ida Skytte, Horwood, L. John, and Fergusson, David M.

Abstract

Previous research has shown that children with high levels of early anxiety/withdrawal are at increased risk of later anxiety and depression. It has also been found that positive parent-child attachment reduces the risk of these disorders. The aim of this paper was to examine the extent to which positive parent-child attachment acted to mitigate the risk of later internalising disorders amongst children with high levels of early anxiety/withdrawal using data from a 30-years longitudinal study of a New Zealand birth cohort. The findings of this study showed that: (a) increasing rates of early anxiety/withdrawal were associated with an increased risk of later anxiety and depression; (b) positive parent-child attachment in adolescence was associated with a decline in the risk of later anxiety and depression; and (c) these associations persisted even after controlling for confounding factors. The implications of these findings for the role of parent-child attachment in mitigating the adverse effects of early anxiety/withdrawal are discussed. It is concluded that positive parent-child attachment in adolescence may act as a compensatory factor which buffers the adverse effects of childhood anxiety/withdrawal on risks of developing later anxiety and depression.

35. Childhood Conduct Problems Are Associated with Increased Partnership and Parenting Difficulties in Adulthood

Author

Raudino, Alessandra, Woodward, Lianne J., Fergusson, David M., and Horwood, L. John

Abstract

This paper uses data from a sample of 337 parents studied at age 30 to examine the linkages between childhood conduct problems assessed at ages 7-9 and later partnership and parenting outcomes. The key findings of this study were: 1) increasing levels of childhood conduct problems were associated with increased risk of partnership difficulties, including relationship ambiguity, inter-partner conflict/violence and lower levels of relationship satisfaction; 2) increasing levels of childhood conduct problems were associated with increased risk of parenting difficulties, including over-reactivity, lax and inconsistent discipline, child physical punishment and lower levels of parental warmth and sensitivity. These findings were consistent across both parent reports and interviewer ratings, and in nearly all cases remained after extensive adjustment for confounding and selection bias. Study findings add to the growing body of evidence documenting the adverse consequences of early conduct problems for later adult interpersonal relationships and parenting behaviors.

36. Age of Menarche and Psychosocial Outcomes in a New Zealand Birth Cohort

Author

Boden, Joseph M., Fergusson, David M., and Horwood, L. John

Abstract

Objective: This study examined associations between age of menarche and psychosocial outcomes in early adulthood, including sexual behavior, mental health, criminal behavior, and education/employment, to identify the possible causal role of earlier age of menarche in increasing risks of adverse outcomes. Method: Data were gathered from 497 female members of a New Zealand longitudinal birth cohort. Outcome measures (to age 18 years) were as follows: pregnancy; sexually transmitted infection (STI); "DSM-IV" major depression, anxiety disorder, alcohol dependence and conduct disorder/ASPD; self-reported crime; convictions; leaving school without qualifications; and unemployment. Associations between age of menarche and outcome measures were then adjusted for confounding factors spanning family background, family functioning, and individual factors. Additional analyses examined sexual behavior outcomes to age 21, and all other outcomes to age 30 years. Results: Analyses showed that sexual behavior outcomes (pregnancy, STI) were significantly associated with age of menarche, even after controlling for confounding factors. Anxiety disorder was marginally (p less than 0.10) associated with age of menarche. In addition, pregnancy during ages 18 to 21 years was significantly associated with age of menarche. There were no significant associations between age of menarche and outcomes at any other age (to age 30). Conclusions: The study showed that females reaching menarche at an earlier age were at increased risk of early pregnancy, and STI by age 18. The present study found little evidence to suggest that age of menarche was related to mental health, criminal behavior, or education/employment outcomes for this cohort. (Contains 4 tables.)

38. Risk Factors for Conduct Disorder and Oppositional/Defiant Disorder: Evidence from a New Zealand Birth Cohort

Author

Boden, Joseph M., Fergusson, David M., and Horwood, L. John

Abstract

Objective: To examine the social, family background, and individual antecedents of conduct disorder (CD) and oppositional defiant disorder (ODD), the extent to which CD and ODD symptoms were predicted by common environmental risk factors, and the extent to which the antecedents of CD and ODD accounted for the comorbidity between the two disorders. Method: Data were gathered from 926 members of a New Zealand longitudinal birth cohort. The outcome measures were DSM-IV symptom count measures of CD and ODD at age 14 to 16 years. Predictors measured during the period from 0 to 14 years included the following: maternal smoking during pregnancy; exposure to socioeconomic adversity; parental maladaptive behavior; childhood exposure to abuse and interparental violence; gender; cognitive ability; and affiliation with deviant peers in early adolescence. Associations between the predictors and outcome measures were modeled using structural equation modeling. Results: The analyses showed that each of the predictors was significantly (p less than 0.05) associated with CD and ODD, with the exception of gender and ODD. After model fitting, the profile of risk factors that predicted CD and ODD were largely similar. The analyses revealed that approximately 40% of the comorbidity between disorders could be accounted for by common factors. Conclusions: The data showed that CD and ODD had largely similar social and environmental antecedents. One implication of this finding is that treatment and prevention approaches that are developed for use with a particular behavior disorder may in fact reduce the incidence of both disorders.

42. Experience of Sexual Abuse in Childhood and Abortion in Adolescence and Early Adulthood

Author

Boden, Joseph M., Fergusson, David M., and Horwood, L. John

Abstract

Objective: The present study examined the associations between the experience of sexual abuse in childhood (CSA) and the number of abortions in adolescence and early adulthood. Method: A 25-year prospective longitudinal study of the health, development, and adjustment of a birth cohort of 1,265 New Zealand children (630 females). Measures included assessments of experience of CSA using retrospective data gathered at ages 18 and 21, self-reported abortions from ages 15 to 25, measures of childhood socio-economic disadvantage, family stability, family functioning, experience of childhood physical abuse, and pregnancy in adolescence and early adulthood. Results: Severity of CSA experience was significantly (p less than 0.01) associated with an increasing rate of abortions during ages 15-25. Adjustment of the association for potentially confounding factors from childhood reduced the magnitude of the association, but it remained marginally statistically significant (p less than 0.10). However, controlling for the mediating effects of pregnancy risk in adolescence and early adulthood reduced the association between experience of CSA and abortion to statistical non-significance (p greater than 0.70). Conclusions: The current study suggested that the association between experience of CSA and increased rates of abortion was mediated by the increased rates of pregnancy associated with CSA experiences. The results suggest a causal chain in which experience of CSA leads to increased rates of pregnancy, which in turn leads to increased rates of abortion. (Contains 3 tables.)

43. Situational and Generalised Conduct Problems and Later Life Outcomes: Evidence from a New Zealand Birth Cohort

Author

Fergusson, David M., Boden, Joseph M., and Horwood, L. John

Abstract

Background: There is considerable evidence suggesting that many children show conduct problems that are specific to a given context (home; school). What is less well understood is the extent to which children with situation-specific conduct problems show similar outcomes to those with generalised conduct problems. Methods: Data were gathered as part of the Christchurch Health and Development Study, a 25-year longitudinal study of a birth cohort of New Zealand children. Information was obtained on: (a) conduct problems during the period 7-9 years; (b) criminal offending during the period 16-25 years; (c) measures of DSM-IV mental disorders and suicidal behaviour over the interval 16-25 years; (d) measures of DSM-IV substance dependence over the interval 16-25 years; and (e) measures of relationship, pregnancy, and parenthood outcomes during the period 16-25 years. Results: Latent-class modelling suggested three distinct groups of children with conduct problems: those with mother reports; those with teacher reports; and those with both mother and teacher reports. Both situation-specific and generalised conduct disorder were associated with increased risk of criminal offending, mental health disorders, substance dependence, and relationship and parenthood issues in late adolescence and early adulthood. Conclusions: There is a need for recognition of the significance of situation-specific conduct problems in both developmental theory and in the treatment of childhood conduct disorders. A focus only on those children with generalised conduct problems is likely to overlook the features and needs of children whose conduct problems are confined to a specific context.

44. Effects of Single-Sex and Coeducational Schooling on the Gender Gap in Educational Achievement

Author

Gibb, Sheree J., Fergusson, David M., and Horwood, L. John

Abstract

This study examined the effects of single-sex and coeducational schooling on the gender gap in educational achievement to age 25. Data were drawn from the Christchurch Health and Development Study, a longitudinal study of a birth cohort of 1265 individuals born in 1977 in Christchurch, New Zealand. After adjustment for a series of covariates related to school choice, there were significant differences between single-sex and coeducational schools in the size and direction of the gender gap. At coeducational schools, there was a statistically significant gap favouring females, while at single-sex schools there was a non-significant gap favouring males. This pattern was apparent for educational achievement both at high school and in tertiary education. These results indicate that single-sex schooling may mitigate male disadvantages in educational achievement. (Contains 3 tables and 1 figure.)

45. Exposure to Childhood Sexual and Physical Abuse and Adjustment in Early Adulthood

Author

Fergusson, David M., Boden, Joseph M., and Horwood, L. John

Abstract

Objective: This research examined linkages between exposure to childhood sexual abuse (CSA) and childhood physical punishment/abuse (CPA) and mental health issues in early adulthood. Method: The investigation analyzed data from a birth cohort of over 1,000 New Zealand young adults studied to the age of 25. Results: Exposure to CSA and CPA was associated with increased risks of later mental disorders including depression, anxiety disorder, conduct/anti-social personality disorder, substance dependence, suicidal ideation, and suicide attempts at ages 16-25. Control for social, family, and individual factors reduced the associations between CPA and mental health outcomes to the point of statistical non-significance. However, there was a consistent finding for CSA to remain associated with increased risks of later mental health problems. After adjustment, those exposed to CSA including attempted or completed sexual penetration had rates of disorder that were 2.4 times higher than those not exposed to CSA. Those exposed to harsh or abusive physical punishment had rates of disorder that were 1.5 times higher than those exposed to no or occasional physical punishment. It was estimated that exposure to CSA accounted for approximately 13% of the mental health problems experienced by the cohort. Findings showed that exposure to CPA had only weak effects on later mental health. It was estimated that exposure to CPA accounted for approximately 5% of the mental health problems experienced by the cohort. Conclusions: Exposure to CSA was associated with consistent increases in risks of later mental health problems. Exposure to CPA had weaker and less consistent effects on later mental health. These findings suggest that much of the association between CPA and later mental health reflects the general family context in which CPA occurs, whereas this is less the case for CSA.

46. Early Motherhood and Subsequent Life Outcomes

Author

Boden, Joseph M., Fergusson, David M., and Horwood, L. John

Abstract

Background: Early motherhood has been linked with a number of adverse outcomes, including mental health difficulties and barriers to completing educational qualifications and workforce participation. The present study examined the extent to which these linkages could be explained by the influence of social, family, and background factors that were associated with early motherhood. Methods: Data were gathered as part of the Christchurch Health and Development Study, a 25-year longitudinal study of a birth cohort of New Zealand children. Information was obtained on: (a) the history of pregnancy and parenthood for female participants over the period 15-21 years; (b) measures of DSM-IV mental disorders and suicidal behaviour over the interval 21-25 years; (c) measures of educational achievement over the interval 21-25 years; (d) measures of welfare dependence, workforce participation, and income over the interval 21-25 years; and (e) childhood, family and related confounding factors. Results: Early motherhood was associated with higher levels of mental health disorders, lower levels of educational achievement, higher levels of welfare dependence, lower levels of workforce participation, and lower income. Control for confounding factors reduced the associations between early motherhood and later mental health disorders to statistical non-significance. However, the associations between early motherhood and later educational achievement and economic circumstances persisted after control for potentially confounding factors. Conclusions: The findings suggest that early motherhood puts young women at risk for educational underachievement and poorer economic circumstances. The linkages between early motherhood and later mental health difficulties can largely be accounted for by childhood, family, and related circumstances that occurred prior to parenthood.

47. Gender Differences in Educational Achievement to Age 25

Author

Gibb, Sheree J., Fergusson, David M., and Horwood, L. John

Abstract

Gender differences in educational achievement were examined in a cohort of 1265 individuals studied from birth to age 25. There was a small but pervasive tendency for females to score better than males on standardised tests and to achieve more school and post-school qualifications. The differences could not be explained by differences in cognitive ability as males and females had similar IQ scores. Teacher ratings of classroom behaviour revealed that males were more prone to inattentive, restless and distractible behaviours and aggressive, antisocial and oppositional behaviours than females. When the associations between gender and measures of educational achievement were adjusted for teacher ratings of classroom behaviour the gender differences were reduced substantially. These results suggest that one approach to reducing gender differences in educational achievement lies in improving classroom behaviour. (Contains 4 tables.)

48. Development of Emotional and Behavioral Regulation in Children Born Extremely Preterm and Very Preterm: Biological and Social Influences

Author

Clark, Caron A. C., Woodward, Lianne J., and Horwood, L. John

Abstract

This study describes the development of emotional and behavioral regulation in a regional cohort of children born extremely preterm (less than 28 weeks gestational age, n = 39), very preterm (less than 34 weeks gestational age, n = 56), and full term (n = 103). At 2 and 4 years, children born at younger gestational ages demonstrated poorer self-regulation across multiple contexts spanning observed interactions, formal cognitive testing, and parental report of child behavior at home. Among children born preterm, the 2 strongest predictors of impairments in self-regulation were the presence of moderate-to-severe cerebral white matter abnormalities on neonatal magnetic resonance and a less sensitive parenting style when children were aged 2 years. Findings support the importance of early neurological development and parenting for developing regulation in children born very preterm.

49. Exposure to Childhood Sexual and Physical Abuse and Subsequent Educational Achievement Outcomes

Author

Boden, Joseph M., Horwood, L. John, and Fergusson, David M.

Abstract

Objective: This paper examined the relationship between exposure to sexual and physical abuse (CSA and CPA) in childhood and later educational achievement outcomes in late adolescence and early adulthood in a birth cohort of over 1,000 children studied to age 25. Method: Retrospective data on CSA and CPA were gathered at ages 18 and 21 and used to form a best estimate of exposure to CSA and CPA. The relationship between CSA, CPA, and self-reported educational outcomes to 25 years was examined using logistic regression models that took into account social background, parental factors, and individual factors. Results: Increasing exposure to CSA and CPA was significantly associated with failing to achieve secondary school qualifications (CSA: B = 0.53, SE = 0.13, p less than 0.0001; CPA: B = 0.62, SE = 0.12, p less than 0.0001), gaining a Higher School Certificate (CSA: B = -0.48, SE = 0.13, p less than 0.001; CPA: B = -0.78, SE = 0.14, p less than 0.001), attending university (CSA: B = -0.29, SE = 0.13, p less than 0.05; CPA: B = -0.45, SE = 0.13, p less than 0.001), and gaining a university degree (CSA: B = -0.54, SE = 0.18, p less than 0.005; CPA: B = -0.64, SE = 0.17, p less than 0.001). Adjustment for confounding social, parental, and individual factors explained most of these associations. After control for confounding factors, omnibus tests of the associations between CSA and outcomes and CPA and outcomes failed to reach statistical significance (CSA: Wald x[squared] (4) = 7.72, p = 0.10; CPA: Wald x[squared] (4) = 8.26, p = 0.08). Conclusions: The effects of exposure to CSA and CPA on later educational achievement outcomes are largely explained by the social, family, and individual context within which exposure to abuse takes place.

50. Birth Order and Educational Achievement in Adolescence and Young Adulthood

Author

Fergusson, David M., Horwood, L. John, and Boden, Joseph M.

Abstract

This paper examines the relationship between birth order and later educational outcomes in a birth cohort of more than 1,000 New Zealand young adults studied to the age of twenty-five. Being later born was associated with gaining fewer educational qualifications at secondary level and beyond. The use of nested models to control for the confounding effects of family size on birth order revealed that birth order effects on educational attainment were not disguised by family size effects. Following adjustment for potentially confounding factors, there remained a statistically significant association between being later born and a lower likelihood of obtaining educational qualifications. It was concluded that the intra-family dynamics initiated by birth order may have a lasting effect on the individual in terms of later educational and achievement outcomes. (Contains 5 tables.)
