The behaviour, development, and health of the young child: implications for care

Predictive Validity and Factors of Direct and Indirect Language Screening Measures for Children Using Panel Data

Objectives: The purpose of this study was to examine whether language abilities, measured by examiners and parents, at age 2 significantly predict later language skills. In addition, this study investigated whether the results of two language screening tests were consistent and which factors affected the agreement of the two measures.Methods: This study analyzed data from 1,739 Korean children who participated in the 3rd (T1, age 2), 6th (T2, age 5), and 10th (T3, age 8) Panel Study of Korean Children (PSKC). The Korean-Denver II test, the Korean-Ages and Stages Questionnaires (K-ASQ), the Receptive & Expressive Vocabulary Test (REVT), and the Multi-Factor Intelligence Test (M-FIT) were utilized to measure children’s language skills. To examine the predictive validity of the two language screening measures, a simple regression analysis was conducted. To investigate the factors affecting the agreement between the results of two measures, parental education level, parental style, knowledge of child development, and child temperament data were used.Results: Both the results of the Korean-Denver II test and K-ASQ at T1 significantly predicted children’s language skills at T2 and T3. It was also found that only parental style was significantly different between the groups classified by the agreement of the two language screening measures at T1.Conclusion: The results of this study revealed that both two language screening measures were valid tools for significantly predicting children’s later language skills. In addition, it was confirmed that the social interaction parental style was a factor affecting parents’ accurate evaluation of their children’s language skills.

Gender and geographic differences in the prevalence of reportable childhood speech and language disability in Taiwan

Speech and language disability (SLD) is not uncommon in children. However, data at the national level are limited, and geographic differences are seldom evaluated. Starting from 1980, the local governments in Taiwan has begun to certify disabled residents for providing various services and report cases to the central government according to the law, and the central government maintains a registry of reported cases, which provides a unique opportunity for studying SLD at the national level. Using the registry data from 2004 to 2010, we calculated the prevalence of SLD by age, gender, and geographic area and assessed the changes over time. Because the government discourages the certification under 3 years of age, we excluded cases under 3 years old from the analyses. We found that from 2004 to 2010 the registered cases between 3 and 17 years old increased from 1418 to 1637 per year, and the prevalence generally increased every year in all age groups except in 12-14 years of age. In each year there were more boy cases than girl cases, and the prevalence rate ratio increased from 1.50 to 1.83 (p < 0.05 in all years), with an increasing trend over time (p < 0.01). A higher prevalence was observed in the rural areas over the years, and the prevalence rate ratio increased from 1.35 to 1.71 (p < 0.05 in all years), with an increasing trend over time (p < 0.01). Further studies identifying the risk factors contributed to the increases might help the prevention of SLD in the future.

Screening for developmental language disability in 3-year-old children. Experiences from a field study in a Swedish municipality

This study evaluates a screening instrument for identification of severe developmental language disability (DLD) in 3-year-old children, which is used as a routine assessment at several child health centres (CHCs) in Sweden. The results are reported in terms of clinical outcome (false- and true-positive rates), kind and extent of DLD, signs of comorbidity and relation between nurses' and parents' observations. More than 60 CHC nurses, all with experience of the screening instrument, assessed in all 2359 3-year-old children (98% of the whole population) by direct observation of their language comprehension, language production and level of co-operation. In addition to the screening parents answered a questionnaire. Children who failed the screening had their hearing assessed and were clinically examined by trained speech and language therapists. Forty-four (34 boys and ten girls) of the 65 referred children were clinically examined. Apart from two false-positive cases most of them were diagnosed as generally and severely language disabled. According to the nurses' observations attention deficit was common among the referred boys, which was later confirmed by the speech therapist in two-thirds of them. Agreement between nurses and parents was poor and only half of the parents were concerned about their child's language development. In the light of this result, continued application of the screening and the use of parent questionnaires is discussed.

The differences in health concerns between mothers and health care professionals in a preventive community set up

To assess the degree to which mothers, nurses and pediatricians share common concerns regarding infants' health and well-being a cross-sectional survey with stratified demographic sampling was conducted. A 12-item questionnaire pertaining to health concerns was administered to 22 mothers of infants between 1 and 18 months of age, treated at six Well Baby community clinics with 36 nurses and 25 pediatricians. Mothers and health care professionals expressed significantly different concerns. Pediatricians and nurses shared a more similar order of concerns. However, they too differed on the degree of concern related to some of the health issues, i.e. nurses perceived the issues related to feeding, behaviour, skin, sleep and daily routines as significantly more important than did pediatricians. Additional efforts should be devoted to improve and clarify communication between mothers and health care professionals.

Conditions accounting for substantial time spent in hospital in children aged 1-14 years

To identify the clinical conditions associated with substantial time spent in hospital by children aged 1-14 years, records of children admitted to hospital in 1975, 1979, and 1984 were studied. Analysis was by linkage of abstracts of routine records of hospital inpatient care in six districts in southern England covered by the Oxford record linkage study. The total time spend in hospital in the acute specialties each year was calculated by summing the lengths of stay of all episodes of care for each child in each year. First, admissions with long median times in hospital per child admitted were identified. These included, notably, fracture of femur and, in the later years, leukaemia, other malignant neoplasms, and congenital disorders of metabolism. Second conditions were identified which accounted for large numbers of children with lengths of stay of five days or more. These included, in particular, congenital anomalies, asthma, and appendicitis. Third, conditions were identified which accounted for the largest numbers of bed days used. These included congenital anomalies, hypertrophy of tonsils and adenoids, asthma, otitis media, appendicitis, and head injury. Median time spent in hospital per child admitted declined for most conditions but increased for leukaemia, other malignant neoplasms, and congenital disorders of metabolism. Admission rates for children who spent five days or more in hospital each year declined for all common conditions except asthma which increased. Total numbers of beds used increased for asthma and otitis media but declined for all other common conditions.

The psychological, educational and auditory sequelae of early, persistent secretory otitis media

Previous studies have suggested an association between chronic middle ear disorders due to secretory otitis media and adverse effects on auditory, educational and psychological development in children. Experimental design of such studies has often been poor. In this study, attempts were made to control extraneous variables more rigorously, using matched pairs. A group of children (n = 10) without current hearing problems but with a history of recurrent early secretory otitis media, aged 7-11 yrs, were compared on auditory, educational and psychological measures with a matched group of children with no history of otitis media. The results indicated weak but distinct differences between the two groups on the educational and psychological measures in favour of the control group. The implications for medical and educational services are outlined.

Preventive health care for preschool children or health surveillance

The debate about provision of health surveillance programmes for preschool children is described. Improvement in the health of the child population has caused a need for its continuance in its present form to be questioned. The aspects of child health and development that still cause concern and the current approaches to them are reviewed. The problem of disadvantaged children and their health needs are discussed. Changes in social policy are required as well as continued initiatives in the provision of preventive health care for vulnerable families.
