A natural history of hyperactivity and conduct problems: self-reported outcome.

At the age of 16-18 years, outcome was prospectively assessed in a general population sample of four behavioural groups, defined at 6-7 year old: a pure pervasively hyperactive group (N = 31), a mixed hyperactive conduct problem group (N = 20), a pure conduct problem group (N = 18) and a normal control group (N = 29). The objective of the present paper is to describe outcome in those domains for which self-report is recognised as a valid source of information. Differential effects for hyperactivity and conduct problems on outcome were studied. It was found that early hyperactivity and conduct problems predicted different patterns of conduct problems in adolescence. Drug use in adolescence was not predicted by either type of behavioural problem in childhood. Overall social adjustment was worse in the hyperactive groups, whereas no differences in self-esteem were found. Hyperactivity was a strong predictor of relationships problems in adolescence. The results suggest that hyperactivity and conduct problems in childhood are differential predictors of outcome in adolescence.

Hyperactivity and reading disability: a longitudinal study of the nature of the association.

In order to investigate the possible causal relationships between hyperactivity and educational underachievement that might account for their frequent co-occurrence, four groups of boys, defined by the presence or absence of hyperactivity and specific reading retardation, were identified in an epidemiological study of 7 8-year-old children. They were examined in detail by means of parental interviews and psychological tests and reassessed 9 years later at the age of 16-18 years on a similar range of measures. The findings provided little support for the idea that persistent reading disabilities either lead to the development of hyperactivity de novo or increased the likelihood that hyperactivity, when present, would persist. Similarly, although features of hyperactivity persisted to follow-up, there was little evidence that they either lead to the development of reading disabilities or increased the likelihood that reading disabilities, when present, would persist. Socioeconomic adversity and a history of speech therapy were more common in the group with both hyperactivity and reading disability, but the strength of these associations made it unlikely that these factors could account for the frequent co-occurrence of the two conditions.

Hyperactivity and conduct problems as risk factors for adolescent development.

OBJECTIVE: To clarify the developmental risk associated with hyperactive behavior, especially the relationship between hyperactive and conduct problems, in a longitudinal epidemiological design. METHOD: A follow-up study of children who were identified, by parent and teacher ratings in a large community survey of 6- and 7-year-olds, as showing pervasive hyperactivity or conduct problems or the comorbid mixture of both problems or neither problem. They were later investigated, at the age of 16 to 18 years, with detailed interview techniques as well as parental and self-report ratings and cognitive tests. RESULTS: Hyperactivity was a risk factor for later development, even allowing for the coexistence of conduct problems. Its sequelae included a high likelihood of psychiatric diagnosis, persisting hyperactivity, violence and other antisocial behaviors, and social and peer problems. CONCLUSIONS: The results suggested a developmental pathway through which hyperactivity raised the likelihood of impaired social adjustment, including the development of psychiatric disorders, independently of the existence of conduct problems.

Mother-child interaction and the cognitive and behavioural development of four-year-old children with poor growth.

A whole population inner-city survey identified 23 stunted, otherwise healthy, children with persistently poor growth from infancy to 4 years. Their cognitive development was significantly retarded relative to a matched comparison group. Unstructured home observations were used to create transcripts of verbal and nonverbal mother-child interactions. In both groups child behavioural adjustment was linked to maternal negativity, and cognitive performance was correlated with quality of stimulation. The developmental delay associated with chronic failure to thrive appeared more likely to arise from other influences, perhaps a previous biological insult, than to contemporaneous parenting practices.

Hyperactivity and delay aversion--II. The effect of self versus externally imposed stimulus presentation periods on memory.

The memory of hyperactive and non-hyperactive children for "attended" and "unattended" picture cards was compared under two conditions. Under Self Imposed Presentation (SI) conditions children set their own limits on presentation time while under Externally Imposed Presentation (EI) conditions children were encouraged to spend 30 seconds attending to the cards. Hyperactive children selected shorter presentation times than non-hyperactive children and recognized fewer "attended" cards under SI conditions, while the two groups performed equally well under EI conditions. These findings suggest that a major determinant of memory deficits in hyperactivity is a self imposed limitation on presentation time rather than more specific cognitive process limitations.

Growth retardation and developmental delay amongst inner-city children.

A whole population survey of an inner-city health district (population 130,000) was undertaken in order to study the association between social deprivation and non-organic growth delay in preschool children. Potential cases were identified from health clinic records. Cases comprised white, full-term singletons, whose weight and height lay below the tenth centile at 4 years of age. Allowance was made for parental stature. A comparison group was closely matched for socio-economic conditions, and other salient variables. Case children were comparatively significantly delayed in all areas of their cognitive development. One-third were seriously retarded and likely to require special education.

Nutrition and mealtime behaviour in families of growth-retarded children.

A sample of 4-year-olds from a London inner city area whose growth fell below the 10th population centile for height and weight were matched with children whose rate of growth was within normal limits. Neither food intake nor gross environmental variables distinguished the two groups. However, mealtime observations revealed considerably more disorganization and negative attitudes in case group families. Retrospective information obtained by interview indicates that these factors had been operative since early infancy. The findings suggest that in surveys of child nutrition the role of family dysfunction should be considered.

Self-report of attention deficit and hyperactivity disorder in adolescents.

The validity of self-report measurement varies widely according to the type of behaviour investigated. For behaviour of overactivity and inattention, adolescents seem to underestimate their problems. Well validated instruments for self-report of attention deficit and hyperactivity disorder (ADHD) are lacking yet, and research on ADHD beyond childhood relies quite heavily on self-report. In this study, an attempt is made to validate an adolescent interview scale for DSM-based ADHD symptoms. Results show that the measure has a high inter-rater reliability and is a good predictor of general outcome. However, adolescents do not validly report on symptoms specifically of ADHD. Possible implications for research and clinical practice are formulated.
