Diet and behaviour | 1989
Williams, S.M., McGee, R.
New Zealand Medical Journal, 1989, 102(102), 499-500.
Our ref: NZ54
This paper reviewed some recent evidence concerning the association between diet and behaviour. It was concluded that the evidence suggested that the link between food and problem behaviour such as hyperactivity and aggression is not as strong as many believe.

Our ref: RO128
Deficits in executive neuropsychological functions have been proposed to underlie the development of antisocial behavior such as juvenile delinquency. Results of research into the executive functions of delinquents have been mixed, and studies have been hampered by reliance on small samples of adjudicated subjects and questionable validity of the tests administered. This research examined the performance of a large unselected birth cohort of adolescent boys and girls on five tests of executive function that have documented reliability and validity. It is the first such study to use self-reports of antisocial behavior. Executive deficits were shown only by a subgroup of delinquent subjects with childhood comorbidity of antisocial behavior and attention deficit disorder; that subgroup's behavior was also rated as more aggressive and impulsive than comparison groups'. Group differences on executive measures remained significant after the effects of overall IQ were statistically controlled. Also, delinquents who had been detected by police did not show poorer executive functions than subjects with equivalent self-reports of delinquent behavior who had evaded official detection, suggesting that executive deficits are related to the development of antisocial behavior itself, and not simply to risk of detection.

A longitudinal study of depression in 9 year old children | 1988

Our ref: RO108
Three groups of 9 year old children defined as having a current depressive disorder, past depressive disorder or no depressive disorder were studied at ages 11 and 13. Significantly more depressive symptoms were found at age 11 and 13 in those who had depressive symptoms at age 9 or previously. There was also a long-term association between depression and antisocial behaviour in boys (but not girls).The results from this study highlighted the differences between child and adult forms of depression.

Archives of General Psychiatry, 1987, 44(44), 69-76.
Our ref: RO65
We investigated the prevalence of previous DSM-III disorders in 792 children aged 11 years from the general population and found an overall prevalence of disorder of 17.6% with a sex ratio (boys-girls) of 1.7:1. The most prevalent disorders were attention deficit, oppositional, and separation anxiety disorders, and the least prevalent were depression and social phobia. Conduct disorder, overanxious disorder, and simple phobia had intermediate prevalences. Pervasive disorders, reported by more than one source, had an overall prevalence of 7.3%. Examination of background behavioral data disclosed that children identified at 11 years as having multiple disorders had a history of behavior problems since 5 years of age on parent and teacher reports. Fifty-five percent of the disorders occurred in combination with one or more other disorders, and 45% as a single disorder.

The relationship between specific reading retardation, general reading backwardness and behavioural problems in a large sample of Dunedin boys: a longitudinal study from five to eleven years | 1986

Journal of Child Psychology and Psychiatry, 1986, 27(27), 597-610.
Our ref: RO83
Parent and teacher reports of behaviour problems were obtained at ages 5, 7, 9 and 11 years for three groups of boys: specific reading retarded (N = 18), general reading backward (N = 22), and those with no severe reading disability (N = 436). At school entry, both groups of reading disabled boys were reported as having more behaviour problems, and the level of problems increased during their early school years. The results suggest that behaviour problems pre-date reading disability, while reading failure further exacerbates the existing problem behaviour.

The Rutter Scale for completion by teachers: factor structure and relationship with cognitive abilities and family adversity for a sample of New Zealand children | 1985

Our ref: RO51
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.

Background characteristics of aggressive, hyperactive and aggressive-hyperactive boys | 1984

Journal of the American Academy of Child and Adolescent Psychiatry, 1984, 23(23), 280-284.
Our ref: RO37
In a previous study by the authors (1984), the behavioral and developmental characteristics of aggressive boys, hyperactive boys and boys who were both aggressive and hyperactive were examined. This report investigates the perinatal histories, maternal and family characteristics of these same groups, and a comparison group not identified as aggressive or hyperactive. The four groups did not differ in terms of their perinatal histories. While boys with problems differed from those without, clear differences among the problem groups did not emerge. The results did suggest, however, that quality of family life varied to some degree among the problem groups.
