Cognitive correlates of depressive symptoms in eleven year old children

Journal of Abnormal Child Psychology, 1986, 14(14), 517-524.
Our ref: RO82

Show abstract » Self-reports of depressive symptoms were obtained for 792 11-year-old New Zealand children using a structured interview. The aim of the present study was to test the hypothesis that depressive symptomatology in children is associated with impairment on cognitive tasks. The results did not support this hypothesis. Depression was unrelated to performance on various subscales of the WISC-R, whereas self-reported inattention was associated with poor performance. Depressive symptoms, however, were significantly related to lower self-esteem and a poorer self-perception of scholastic ability.

Swimming experiences and abilities of nine year olds

British Journal of Sports Medicine, 1986, 20(20), 39-41.
Our ref: RO75

Show abstract » As part of a longitudinal study of children, 941 mothers were asked to report on their childrens' swimming experiences and abilities. At age nine, twenty-nine per cent of the children could swim only a few strokes or not at all. A disproportionate number of children who could swim more than a few strokes came from high socio-economic backgrounds, from families where one or more of the parents could swim, and which scored higher on an index of active recreational orientation. There were no significant sex differences in swimming ability. There were 97 incidents reported where a child had been in difficulties while in water and had to be rescued. The importance of collecting data on such incidents is discussed.

The stability and classification of specific reading retardation: a longitudinal study from age seven to eleven

British Journal of Educational Psychology, 1986, 56(56), 32-39.
Our ref: RO67

Show abstract » SUMMARY: The concept of specific reading retardation assumes that there exists a stable group of under-achieving children whose classification is not simply age- or test-specific. This assumption was investigated longitudinally in a large sample of New Zealand children who were followed from age 7 to age 11 . Substantial overlap was found between groups classified as specific reading retarded at ages 7, 9, and 11 on the basis of Burt reading and WISC-R Performance 1Q scores. At age 11, there was also substantial agreement between classifications based on three separate measures of reading achievement, although there was evidence of test-specific factors unique to comprehension- versus word recognition-based classifications. Agreement between classifications at age I1 based on WISC-R Performance 1Q and Fullscale IQ was high. The data indicated the existence of a fairly stable group of children characterised by enduring under-achievement in reading throughout the primary years of schooling.

Our ref: RO64

Show abstract » This paper reports some psychometric properties of the Malaise Inventory of Rutter and colleagues from a longitudinal study of a large sample of New Zealand mothers. Malaise scores were relatively stable over time and the scale showed good psychometric properties. The measure was also sensitive to potential sources of adversity in the backgrounds of the women. Some recommendations regarding a number of the questionnaire items are made.

Our ref: NZ41

Show abstract » A cohort of approximately 500 boys was screened for retained testes at ages five and seven years and when the boys were aged three, five, seven and nine years, their parents were questioned about hospitalisation for surgery. Orchidopexy for retained testes had been performed on 15 of the 536 boys (2.8%) while one other had orchidopexy for high retractile testes (0.2%). Eighty-one percent of this surgery was performed between the seventh and ninth years of age.

Pattern of caries in permanent incisors and first molars in 9-year-old children [Abstract]

Journal of Dental Research, 1985, 64(64), 650.
Our ref: RO73

Show abstract » In 1981-82, 697 children in the Dunedin Multidisciplinary Health and Development Study had dental examinations at age 9. The examinations, by one investigator (GWS), occurred in school dental clinics using the same light source and standardised probes. The mean DMF-T score was 0.98, and mean DMF-S score was 1.21. The permanent dentitions of 54% of children were caries-free; 99% had all permanent incisors unaffected by caries, and 55% had all first permanent molars unaffected by caries. The percentages of surfaces of upper first permanent molars affected by caries were: occlusal 21%, mesial 1.2%, distal 0.9%, palatal 3.7%, buccal 1.0%. The corresponding figures for lower first permanent molars were: occlusal 17.9%, mesial 1.2%, distal 0.2%, lingual 0.2%, and buccal 10.9%. Prevention of fissure caries in this age group is a priority if further reduction in DMF is to be achieved.

The prevalence of bronchial reactivity to inhaled methacholine in New Zealand children

Thorax, 1985, 41(41), 283-289.
Our ref: RO72

Show abstract » The prevalence of bronchial hyperreactivity to inhaled methacholine and of a clinical history of symptoms of asthma was determined in a birth cohort of 9 year old New Zealand children. A history of current or previous recurrent wheezing was obtained in 220 of 815 children. Of 800 who had spirometric tests, 27 (3.4%) had resting airflow obstruction (FEV1/FVC less than 75%). Methacholine challenge was undertaken without problem in 766 children, the abbreviated protocol being based on five breaths and four concentrations. A fall in FEV1 of more than 20% was observed in 176 children (23% of challenges, 22% of the full cohort) after inhalation of methacholine in concentrations of up to 25 mg/ml. The prevalence of bronchial reactivity in children with symptoms was related to the frequency of wheezing episodes in the last year, and the degree of reactivity to the interval since the last episode. Sixty four children (8.0%) with no history of wheeze or recurrent dry cough were, however, also responsive to methacholine 25 mg/ml or less, while 35% of children with current or previous wheezing did not respond to any dose of methacholine. Bronchial challenge by methacholine inhalation was not sufficiently sensitive or specific to be useful as a major criterion for the diagnosis of asthma in epidemiological studies. The occurrence of airway reactivity in children without symptoms of asthma, however, raises the possibility that adult onset asthma and the development of airways obstruction in some subjects with chronic bronchitis could have origins in childhood.

The growth and development of twins compared with singletons at ages nine and eleven

Our ref: RO70

Show abstract » The growth and development of 9 and 11-year old twins who have been studied at birth, and at ages 3, 5, and 7 years was compared with that of a large group of singletons. The twins were not significantly different to the singletons in language development, reading, spelling or Performance IQ. They remained significantly shorter, lighter and had smaller head circumferences. This difference was shown to have been fairly consistent from age 3. The twins had significantly lower Verbal and Full Scale IQ, but in view of a lack of disadvantage in educational progress this was not considered to be of any practical importance.

Sleep in middle childhood - a longitudinal study of sleep problems in a large sample of Dunedin children aged 5 to 9 years

Australian Paediatric Journal, 1985, 22(22), 31-35.
Our ref: RO63

Show abstract » Complaints of sleeping difficulties in a large group of New Zealand children were studied prospectively over four years from 5 to 9 years of age. No association was found between sleeping difficulties and the sex, intelligence, or educational attainments of the child. Mothers who described their child as anxious or who were poor sleepers themselves tended to report sleeping problems in their child more frequently. There was no association between sleeping problems and teacher ratings of behaviour problems. Children who reported sleep problems also tended to report other problems. There was low agreement between parents and children. Only 0.3% of the total sample had a problem which persisted over the whole period.

Factor structure and correlates of ratings of inattention, hyperactivity, and antisocial behavior in a large sample of 9-year-old children from the general population

Journal of Consulting and Clinical Psychology, 1985, 53(53), 480-490.
Our ref: RO60

Show abstract » Teacher ratings of inattentive, impulsive, hyperactive, aggressive and anxious behaviours were obtained for a non-clinic-referred sample of 926 9-year-old children from Dunedin, New Zealand. Factor analysis of the ratings identified four factors of Inattention, Antisocial Behaviour, Hyperactivity, and Worry-Fearful. Subscales based on these factors were only weakly related to parent ratings of the same behaviours. Canonical correlational analysis indicated that both cognitive (performance IQ, reading and spelling) and motor (speech articulation and tapping speed) abilities best predicted the parent and teacher ratings of inattention. Family background measures, on the other hand, were associated primarily with the antisocial, hyperactive and worry ratings. Overall, the results suggest that inattention represents the core dysfunction in hyperactivity. it is argued that inattention, hyperactvity and antisocial behaviours should be regarded as at least partially independent dimensions.

Some factors influencing the stature of Dunedin 7 year old children: a report from the Dunedin Multidisciplinary Health and Development Research Unit

Australian Paediatric Journal, 1985, 21(21), 27-30..
Our ref: RO59

Show abstract » The stature of 987 representative Dunedin 7 year olds was measured and some factors contributing to stature were studied in 666 children for whom complete data were available. Dunedin children were of similar stature to American children but were about 1 cm taller than British children. Socio-economic status (SES), birthweight and maternal stature were significantly correlated with stature, while the sex of the child, gestational age, maternal age, ordinal position of the child in the family and number of children in the family were not significantly correlated. The effect of SES in Dunedin was much less than that reported for the United Kingdom. It was concluded that in this population, SES and family structural factors are probably less important as determinants of child growth than they are in Britain and are of considerably less importance than the mother's stature and the child's birth weight.

Children's attachment to soft objects at bedtime, child rearing, and child development

Journal of the American Academy of Child and Adolescent Psychiatry, 1985, 24(24), 442-446.
Our ref: RO57

Show abstract » Research and theories about children's emotional attachment to blankets and soft toys are reviewed. New research is presented from an extensive study in Dunedin, New Zealand, on two samples of children between 18 months and 5 years. Interviews, questionnaires, and psychometric tests were given to the children and their mothers. Children who were emotionally attached to an object appeared to mature and adjust like other children. The only difference was that they were more likely to have a sucking habit. Mothers did not differ intellectually or in matters of discipline, adjustment, and child rearing. The younger children in the most affluent families were more likely to become attached compared with those from less affluent families, but survey techniques are inadequate for linking cause and effect which requires intensive observational studies during the first year of life.

Our ref: RO56

Show abstract » From a sample of 818 children, 211 were involved in 256 separate incidents which resulted in 283 injuries requiring medical attention. The most common injuries were lacerations, abrasions and contusions, fractures, concussion, and sprains. The majority of the injuries were minor. The most common incident resulting in injury was a fall, followed by incidents where the child struck against or was struck by an object or persons and incidents involving sharp objects. The nature and circumstances of the serious injuries is presented in detail. Methods of improving the description and the classification of childhood injuries and some incidents worthy of further investigation are discussed.

Lack of long term effect of method of infant feeding on growth

Human Nutrition: Clinical Nutrition, 1985, 39(39), 39-44.
Our ref: RO55

Show abstract » Although we have found that, at 7 years of age, children who were exclusively breast-fed in the first 3 months of life are significantly taller and slightly heavier than those exclusively formula-fed, correction for a variety of other familial factors can explain most of the differences. The breast-fed were longer at birth, had taller mothers, and came from families of higher socioeconomic status, although the last appears to act via maternal stature. There was no difference between the groups at age 7 in skeletal maturity, nor in fatness as measured by combined triceps plus subscapular fatfold. Apparent associations between the method of infant feeding and findings in later childhood must thus be interpreted with caution, since they may reflect differences between the characteristics of families choosing different methods of feeding rather than an effect of the feeding method itself.

The Rutter Scale for completion by teachers: factor structure and relationship with cognitive abilities and family adversity for a sample of New Zealand children

Journal of Child Psychology and Psychiatry, 1985, 26(26), 727-739.
Our ref: RO51

Show abstract » A large sample of 7-year-old children (n = 940) was rated by teachers using the Rutter Child Scale B, a 26-item questionnaire covering a variety of behavioural problems. A factor analysis of the data revealed three main factors of interest, identified as aggressiveness, hyperactivity and anxiety-fearfulness. Measures based upon these factors had a reasonably high level of reliability and were moderately stable over a 2-year interval. An analysis of the relationship between these three behavioural measures and some cognitive measures indicated that only hyperactivity was negatively associated with cognitive ability. However, both hyperactivity and aggressiveness were related to adversity in the child's family background. The findings suggest the usefulness of distinguishing between aggressive and hyperactive dimensions of behaviour.

Laterality, cognitive ability and motor performance in a sample of seven year olds

Journal of Human Movement Studies, 1985, 11(11), 59-68.
Our ref: RO50

Show abstract » SUMMARY This study examined hand, eye, and foot laterality in a sample of 890 7-yr-old children to determine whether the degree of left and right congruence between hand, eye, and foot preference related to a variety of measures of cognitive ability or motor performance or whether there was an association between hand, eye, and foot preferences and differences in cognitive ability and motor performance. With regard to left and right congruence, the only significant difference found related to a test of target throwing. There was a decrease in target throwing ability with decreased total left or right congruence. When the sample was grouped according to strength of left or right preference and all the measures were compared, there were no significant differences. Overall, this study found no significant association between any aspect of laterality studied and cognitive ability and only one significant association between laterality and a measure of motor performance. The implications of these results are discussed.

Some characteristics of nine year old boys with general reading backwardness and specific reading retardation

Journal of Child Psychology and Psychiatry, 1985, 26(26), 407-421.
Our ref: RO44

Show abstract » In 1975 Rutter and Yule distinguished between 'specific reading retardation' and 'general reading backwardness'. In a sample of 952 9-year-olds from Dunedin, New Zealand, 4.2% were identified as specific reading retarded and 4.1% as having general reading backwardness. Boys from each problem group were compared with boys without reading delay. General reading backwardness was associated with a history of long-term cognitive and motor delay. Specific reading retardation was only associated with lower verbal IQ and poor speech articulation. A number of differences between the findings of Rutter and Yule and the present results were noted.

The prevalence of smoking among nine year olds

New Zealand Medical Journal, 1984, 77(77), 528-531.
Our ref: NZ39

Show abstract » This study reported the results of a survey on smoking conducted by the Dunedin Multidisciplinary Health and Development Research Unit of 779 nine year old children in their sample. By the age of nine, 275 (35.3%) of the children had tried to smoke a cigarette, even just a few puffs, and 636 (81.7%) did not have any friends who smoked. Most of these children knew about the adverse effects of smoking on health and most of this information did not come from their parents. They also reported that 63% of the mothers and 75% of the fathers did not give them information on smoking. The findings suggested (1) that health education programmes for the prevention of smoking by children should start prior to age nine (2) that a programme focusing on the negative aspects of smoking on health would probably not be very beneficial and (3) that parents should be recruited as health educators and used more efficiently in giving children more information about smoking.

Factors associated with the initiation of smoking in nine year old children

Journal of Addictive Diseases (fmr Advances in Alcohol and Substance Abuse), 1984, 5(5), 79-89.
Our ref: RO48

Show abstract » The present study examined the relationship between 787 (415 boys and 372 girls) nine year old children's reported experience with cigarettes and the parents, home environment, peers, socioeconomic status, school performance and behavior or emotional problems and delinquency factors which had in the past been found to be influential during the formative stages of initiation into the use of tobacco. The 787 children (415 boys and 372 girls) were classified as either puffers (those who had puffed on a cigarette) or nonpuffers. The results suggest than, at age nine, puffers were more likely than nonpuffers to: intend to smoke in the future; have one or both parents smoking; have one, or more, smoking friend(s); do less well at maths and school work in general; misbehave more often; and be taken to see a psychologist regarding a behavioral or emotional problem.

Academic self-concept: Some developmental and emotional correlates in nine-year-old children

British Journal of Educational Psychology, 1984, 54(54), 284-292.
Our ref: RO47

Show abstract » Eight hundred 9-year-old children being studied by the Dunedin Multidisciplinary Health and Development Research Unit were assessed in terms of academic self-concept, intelligence, and school performance. A short form of the Student's Perception of Ability Scale (SPAS) was used to estimate academic self-concept. Intelligence was assessed by the Wechsler Intelligence Scale for Children-Revised (WISC-R), reading by the Burt Word Reading Test, spelling by a short form of the Dunedin Spelling Test, comprehension and expression by the respective subscales in the Illinois Test of Psycholinguistic Abilities (ITPA), and school achievement by parents' perceptions of current attainment levels. The results indicate that the SPAS Short Form yields means, standard deviations, and internal reliability estimates that are consistent with other studies. In addition, sex differences were noted, with girls reporting slightly higher self-perceptions of ability than boys. In terms of correlations between academic self-concept and school-related ability and performance, it was found that SPAS subject-specific subscale scores correlated moderately with corresponding subject area performance, but weakly or negligibly with WISC-Rand ITPA Comprehension and Expression scores. Perceptions of ability, therefore, appear to be relatively independent of intelligence,
and more related to success levels in school. It was also found that children identified as reading retarded had significantly lower self-perceptions of ability than normal readers. Similarly, depressed children indicated relatively negative self-concepts compared to past depressed and non-depressed children.
