A comparative study of infantile autism and specific developmental receptive language disorders. III. Discriminant function analysis.

A psychometric, observational, and interview study was undertaken with 47 boys, aged 4 1/2 to 10 years, with nonverbal IQs of 70+ and a severe developmental disorder of language comprehension. Separate discriminant function analyses, based on behavioral, language, or cognitive features, showed little overlap between clinically defined autistic and dysphasic subgroups. Moreover, the discrimination could be made as clearly on language or cognitive characteristics as on social or behavioral critera. Language abnormalities and behavioral features also intercorrelated within the autistic subgroup. It is concluded that autism and dysphasia differ in important ways and that a cognitive deficit is an essential part of the syndrome of autism.

Bias resulting from missing information: some epidemiological findings.

The biases resulting from missing information were examined in three psychiatric epidemiological studies. In each study, cases with missing information could be compared with the main sample because data were available from several sources or at several points in time through a longitudinal study. In almost all instances, cases with missing data differed systematically in terms of variables crucial to the questions being studied. In general, they tended to include a higher proportion with problems of various kinds--such as, behavioural deviance, reading backwardness, child or adult psychiatric disorder, and marital discord. The characteristics or circumstances of those giving information were generally more strongly associated with co-operation in testing or interviewing than the characteristics of those about whom information was sought. In some situations, the nature and degree of distortion resulting from missing information could lead to biased results.

Differences between mentally retarded and normally intelligent autistic children.

Autistic children with an IQ below 70 and with an IQ above 70 were systematically compared. The two groups differed somewhat in the pattern of symptoms, but were closely similar in terms of the main phenomena specifically associated with autism. However, the low IQ and high IQ autistic children differed more substantially in terms of other symptoms such as self-injury and stereotypies and there were major differences in outcome. The possibility that the nature of the autistic disorder may differ according to the presence or absence of associated mental retardation needs to be taken into account in planning studies of etiology.

An evaluation of an interview assessment of marriage.

An interview assessment of marriage relationships is described. It is shown to have good inter-rater reliability, high consistency across the accounts of both marriage partners and to be resistant to methodologic bias. A four-year follow-up study demonstrated high predictive validity to later marriage breakdown. The marriage measure also showed a strong association with behavioural deviance in the children. The intercorrelations between individual measures of various aspects of the marriage and the summary are given. A shortened version of the interview is described and preliminary findings are given on its validity.

Early hospital admissions and later disturbances of behaviour: an attempted replication of Douglas' findings.

This study confirms the findings of Douglas (1975) that single hospital admissions of children for up to a week carry no increased risk of later emotional or behavioural disturbance. The study also confirms Douglas' finding that repeated hospital admissions are significantly associated with disturbance in later childhood. The association probably applies to both emotional and conduct disorders, is most marked in the case of children from disadvantaged homes, and it may well reflect a causal influence. The validity of the finding is strengthened by the fact that detailed psychiatric assessments gave rise to much the same findings as did teacher questionnaire scores. However, in both cases, repeated hospital admissions are associated with only a small minority of disorers and account for little of the variance in children's behaviour.

Psychiatric outcome of localized head injury in children.

Previous studies have shown a high prevalence of psychiatric disturbance in children with brain injury. Studies on localized lesions have suggested that injury to the young organism carries a better prognosis for recovery of function than injury at a later age. The present study was designed to investigate these phenomena systematically. A representative sample of children (n = 98) who had been hospitalized for treatment of a compound depressed fracture, associated with a dural tear and visible damage to the underlying cortex, was identified from the records of neurosurgical units throughout the United Kingdom. The children were aged between 3 months and 12 years at the time of injury and between 5 and 15 years at the time of examination. The interval between injury and examination varied but the sample was designed to include only children who had been injured at least two years before examination. The children were examined neurologically and psychometrically, a detailed account of their current psychiatric state was obtained from one or both parents, and their mental state was assessed in a standard psychiatric examination. Preliminary data are presented which relate psychiatric, educational and intellectual status at the time of examination to site and severity of injury, age at injury, and to a number of psychosocial variables.

Psychological disorders in crippled children. A comparative study of children with and without brain damage.

A detailed standardised study was made of all crippled children aged between five and 15 years and of normal intelligence on the local-authority lists of handicapped children in three London boroughs. Psychiatric disorder was twice as common in children whose crippling was due to cerebral disease or damage rather than some peripheral lesion. As the groups were well matched in terms of physical incapacity and social background, it was concluded that brain damage was responsible for the children's increased vulnerability to emotional problems. Brain damage was also associated with a marked increase in reading difficulties and a lowering of intelligence within the normal range. Psychiatric disorder was found to be related not only to cerebral injury but also to various types of family disturbance. It is concluded that emotional and behavioural disturbance stemmed from both an increased biological vulnerability and psychosocial hazards.
