Awareness of children's developmental problems and sharing of concerns with parents by preschool teachers and childcare workers: The Japanese context.

BACKGROUND: This study aims to determine the extent to which preschool teachers and childcare workers are aware of the presence of developmental problems among children and to what extent they share information with parents about their concerns regarding a child's development or diagnosis of neurodevelopmental disorders (NDDs). METHODS: We wrote to all 924 preschools and childcare centres in Japan's Nagano and Yamanashi prefectures to request participants. We then sent survey forms to the preschools and childcare centres that agreed to cooperate for three grades comprising 3-, 4- and 5-year-olds in the school year 2020. We asked the staff member in charge of each child to complete the survey. The survey included questions about the teacher's concerns regarding the possibility of an NDD and whether the matter had been shared with the children's parents. RESULTS: We obtained data for 10 354 children from 206 preschools and childcare centres (response rate = 22.3%). Among these children, 457 (4.4%) had an NDD diagnosis that their parents shared with the teachers. However, the teachers of 1274 children (12.3%) had concerns regarding their development but were not informed by the parents about the diagnosis, if any. These 1274 children included 775 (60.8%) cases where the teachers failed to share their concerns with parents because (1) the teachers could not communicate with parents (n = 119), (2) the teachers were not sure if there was a neurodevelopmental problem (n = 360) and (3) the parents were not aware of the problem (n = 296). CONCLUSIONS: Preschool teachers and childcare workers had concerns about the development of a substantial proportion of children in their charge. However, teachers and childcare workers did not share their concerns regarding many children's developmental problems with their parents. The findings suggest that there are challenges in information-sharing between teachers/childcare workers and parents.

Effects of work-family life support program on the work-family interface and mental health among Japanese dual-earner couples with a preschool child: A randomized controlled trial.

OBJECTIVES: This study examined the effectiveness of a newly developed work-family life support program on the work-family interface and mental health indicators among Japanese dual-earner couples with a preschool child(/ren) using a randomized controlled trial with a waitlist. METHODS: Participants who met the inclusion criteria were randomly allocated to the intervention or the control groups (n = 79 and n = 85, respectively). The program comprised two 3-h sessions with a 1-month interval between them and provided comprehensive skills by including self-management, couple management, and parenting management components. The program sessions were conducted on weekends in a community center room with 3-10 participants. Outcomes were assessed at baseline, 1-month, and 3-month follow-ups. Primary outcomes were work-family balance self-efficacy (WFBSE), four types of work-family spillovers (i.e., work-to-family conflict, family-to-work conflict, work-to-family facilitation, and family-to-work facilitation), psychological distress, and work engagement reported by the participants. RESULTS: The program had significantly pooled intervention effects on WFBSE (P = .031) and psychological distress (P = .014). The effect sizes (Cohen's d) were small, with values of 0.22 at the 1-month follow-up and 0.24 at the 3-month follow-up for WFBSE, and -0.36 at the 3-month follow-up for psychological distress. However, the program had nonsignificant pooled effects on four types of work-family spillovers and work engagement. CONCLUSIONS: The program effectively increased WFBSE and decreased psychological distress among Japanese dual-earner couples with a preschool child(/ren).

Extraction and Refinement Strategy for detection of autism in 18-month-olds: a guarantee of higher sensitivity and specificity in the process of mass screening.

BACKGROUND: For early detection of autism, it is difficult to maintain an efficient level of sensitivity and specificity based on observational data from a single screening. The Extraction and Refinement (E&R) Strategy utilizes a public children's health surveillance program to produce maximum efficacy in early detection of autism. In the extraction stage, all cases at risk of childhood problems, including developmental abnormality, are identified; in the refinement stage, cases without problems are excluded, leaving only cases with conclusive diagnoses. METHODS: The city of Yokohama, Japan, conducts a routine child health surveillance program for children at 18 months in which specialized public health nurses administer YACHT-18 (Young Autism and other developmental disorders CHeckup Tool), a screening instrument to identify children at risk for developmental disorders. Children who screen positive undergo further observation, and those without disorders are subsequently excluded. To study the efficacy of early detection procedures for developmental disorders, including autism, 2,814 children born in 1988, examined at 18 months of age, and not already receiving treatment for diseases or disorders were selected. RESULTS: In the extraction stage, 402 (14.3%) children were identified for follow-up. In the refinement stage, 19 (.7%) of these were referred to the Yokohama Rehabilitation Center and diagnosed with developmental disorders. The extraction stage produced four false negatives, bringing total diagnoses of developmental disorders to 23 (.8%) - including 5 with autistic disorder and 9 with pervasive developmental disorder - not otherwise specified (PDDNOS). Sensitivity was 60% for autistic disorder and 82.6% for developmental disorders. Specificity for developmental disorders rose to 100% with the E&R Strategy. Picture cards used in YACHT-18 provided a finer screen that excluded some false positive cases. CONCLUSIONS: An extraction and refinement methodology utilizing child health surveillance programs achieve high efficacy for early detection of autism.

Cumulative incidence of childhood autism: a total population study of better accuracy and precision.

Most studies on the frequency of autism have had methodological problems. Most notable of these have been differences in diagnostic criteria between studies, degree of cases overlooked by the initial screening, and type of measurement. This study aimed to replicate the first report on childhood autism to address cumulative incidence as well as prevalence, as defined in the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10) Diagnostic Criteria for Research. Here, the same methodological accuracy (exactness of a measurement to the true value) as the first study was used, but population size was four times larger to achieve greater precision (reduction of random error). A community-oriented system of early detection and early intervention for developmental disorders was established in the northern part of Yokohama, Japan. The city's routine health checkup for 18-month-old children served as the initial mass screening, and all facilities that provided child care services aimed to detect all cases of childhood autism and refer them to the Yokohama Rehabilitation Center. Cumulative incidence up to age 5 years was calculated for childhood autism among a birth cohort from four successive years (1988 to 1991). Cumulative incidence of childhood autism was 27.2 per 10000. Cumulative incidences by sex were 38.4 per 10000 in males, and 15.5 per 10000 in females. The male:female ratio was 2.5:1. The proportions of children with high-functioning autism who had Binet IQs of 70 and over and those with Binet IQs of 85 and over were 25.3% and 13.7% respectively. Data on cumulative incidence of childhood autism derived from this study are the first to be drawn from an accurate, as well as precise, screening methodology.
