Cross-validation of short forms of the WISC-R in two British samples.

Short forms of the WISC-R were computed by multiple linear regression on two samples of British children aged 6 to 12 years. The predictive validity of each short form was assessed both within the sample on which it was developed and cross-validated on the other sample. The empirically determined loss of power of prediction was found to be less than expected on a priori grounds. Predictions of individual scores at the lower end of the IQ distribution were less acceptable. It is concluded that short forms are robust and of value in research and for screening purposes, but cannot be recommended for clinical purposes.

Cognitive abilities and behavioural characteristics of children with idiopathic infantile hypercalcaemia.

An investigation of the psychological characteristics of 44 children aged 6-16 years with documented evidence of idiopathic infantile hypercalcaemia revealed cognitive abilities and behavioural patterns which distinguish these children from other mentally handicapped groups. The children were all mildly to severely mentally handicapped, but exhibited superior verbal skills compared to their visuo-spatial and motor abilities. They showed high rates of behavioural disturbance, particularly in terms of hyperactivity, social isolation, anxiety, and eating and sleeping difficulties. Other aspects of behaviour, spoken language and personality that were commonly encountered are also described and quantified. From these observations approaches to remedial teaching are suggested.

The relationship between blood-lead concentrations, intelligence, attainment and behaviour in a school population: the second London study.

This study replicates an earlier one carried out in London in which an association was found between lead and intelligence, reading and spelling. In the present study 194 children living near an urban motorway were given the same battery of tests as well as an extensive family interview to determine background variables. Before social factors were taken into account there were no significant associations between lead and outcome variable. Possible reasons for the negative results from this study are discussed.

Age at diagnosis and abilities in idiopathic hypercalcaemia.

Forty three children aged 6 to 16 years with a documented history of idiopathic infantile hypercalcaemia were assessed on a variety of cognitive and behavioural measures. No relation was found between the age at which hypercalcaemia was diagnosed and subsequent full scale intelligence quotients (IQ) and reading or spelling abilities. Verbal IQ was, however, significantly higher than performance IQ, which had an inverse relation with age at diagnosis. Furthermore, scores for deviant behaviour were found to correlate with age at diagnosis. Thus the characteristic psychological profile of this syndrome may be in part a function of hypercalcaemia during infancy.

Automated testing of reaction time and its association with lead in children.

Following Needleman et al.'s (1979) report of a correlation between tooth lead estimates in children and reaction time as measured by Rodnick and Shakow's (1940) delayed reaction time paradigm, a version of the procedure with two delay periods of 3 s and 12 s was developed for automated presentation and scoring on a VIC-20 microcomputer. Data are presented from a study of 300 children aged 6-14 years. Mean reaction time over six trials for each delay period related in a curvilinear fashion with age, but no relationships were found with sex or intelligence. Age-adjusted reaction time related significantly with blood-lead levels, but accounted for only about 1 per cent of the variance. The effect was mainly observed in younger (6-10 years) children in whom higher lead was associated with slower reaction time.

The psychological characteristics of infantile hypercalcaemia: a preliminary investigation.

A sample of 23 children aged seven to 12 years with diagnoses of infantile hypercalcaemia was assessed on a battery of psychological tests and rating scales in an attempt to describe the psychological characteristics of this disorder. All children were found to have a mild or moderate degree of mental handicap. As a group, their expressive language skills were superior to their verbal comprehension. They displayed a high degree of behaviour and emotional disorders, most notably in terms of high levels of activity. Most children were reported as being highly sensitive to noise. This study clarifies some of the psychological correlates of infantile hypercalcaemia and some implications for management are suggested.

Childhood nocturnal enuresis: factors associated with outcome of treatment with an enuresis alarm.

A study was carried out to assess the factors that may affect the outcome of a single course of treatment for childhood nocturnal enuresis by use of an enuresis alarm. 113 children were treated and followed up; those showing failure of initial arrest of wetting, relapse and longterm successful outcome were analysed separately. Emphasis is placed on the need for the adoption of clear criteria regarding the definition of these three groups, and for an adequate follow-up of treated cases. Unsatisfactory housing conditions and circumstances giving rise to family difficulties were significantly associated with a less favourable rate of initial arrest. In the long term, family difficulties again were found to be significantly related to poor outcome. Behavioural deviance, as revealed by a teacher's behavioural questionnaire also adversely affected long-term success, although less significantly so. Family difficulties emerged as the most important predictor for outcome of treatment and adversely influenced the rate of initial arrest of wetting, the relapse rate and the long-term success rate.

Social skills problems in neurotic outpatients. Social skills training with and without cognitive modification.

Twenty-two "socially dysfunctional" outpatients had 12 1 1/2-hour sessions of social skills training either alone or combined with cognitive modification (each, n = 11). Two raters who were blind to the treatment regimen significantly differentiated the two treatments, as judged from audiotapes of treatment sessions. Measurement was by an independent assessor in a structured interview, by self-monitoring of several activities and of anxiety felt during them, and by self-rated questionnaires. In each treatment regimen, patients' conditions improved significantly and equally on reported behavioral and cognitive measures both during and after treatment, and at six-month follow-up. Outcome did not differ significantly between the two treatment conditions at any time on any measure. Patients reported increased levels of social activities and less anxiety during these, less isolation, better relations with their colleagues at work, less depression, and loss of many irrational social beliefs. During multiple baseline monitoring for up to nine weeks, no improvement occurred. Performance of each social task or "target" increased significantly after training was begun for it, and subjective anxiety decreased similarly during social performance. Untreated targets improved much less, and more slowly. Social skills training was followed by lasting and worthwhile improvement that was not enhanced by the addition of cognitive modification.

Issues and problems in remedial education.

Children with reading and other education problems present for help to a wide variety of professionals from different disciplines. At present there appears to be a wide gulf between sophisticated assessments and effective remedial intervention. This paper examines some of the issues involed in providing and evaluating remedial education, and the issues of definition, measurement and prevalence; it is concluded that as many as 20 per cent of 10-year-olds in inner cities in the United Kingdom may require extra help with reading. The evidence suggests that, over-all, remedial help is not at present very effective. A concerted research programme is needed to identify effective approaches. Constructive suggestions are advanced whereby such a research programme would make a significant contribution to services for children with educational problems.
