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 / Hideo HONDA in Journal of Child Psychology and Psychiatry, 50-8 (August 2009)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 50-8 (August 2009) . - p.972-981 Titre : 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 Type de document : Texte imprimé et/ou numérique Auteurs : Hideo HONDA, Auteur ; Yasuo SHIMIZU, Auteur ; Yukari NITTO, Auteur ; Miho IMAI, Auteur ; Takeshi OZAWA, Auteur ; Mitsuaki IWASA, Auteur ; Keiko SHIGA, Auteur ; Tomoko HIRA, Auteur Année de publication : 2009 Article en page(s) : p.972-981 Langues : Anglais (eng) Mots-clés : Autism early-detection screening sensitivity specificity pervasive-developmental-disorder Index. décimale : PER Périodiques Résumé : 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.

The earlier, the better? Diagnostic experiences of parents in a community-based early intervention system for preschool children with autism / Mitsuaki IWASA in Autism & Developmental Language Impairments, 4 (January-December 2019)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 4 (January-December 2019) Titre : The earlier, the better? Diagnostic experiences of parents in a community-based early intervention system for preschool children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Mitsuaki IWASA, Auteur ; Yasuo SHIMIZU, Auteur ; Ikuko HARA, Auteur ; Miho IMAI, Auteur ; Hideo HONDA, Auteur Index. décimale : PER Périodiques Résumé : Background and aimsIn many countries, early detection and diagnosis of autism spectrum disorder is largely dependent on parents? initial concern with early symptoms of autism spectrum disorder. Previous research on parental perceptions of the autism spectrum disorder diagnostic process indicates that parental satisfaction may be due to either the timing of the diagnostic notification or the provision of post-diagnostic support. The objective of this research is to study the diagnostic notification process and its impact on parents who are informed of their young child?s diagnosis before they notice a problem and whose child undergoes early intervention therapy.MethodsEighty parents of preschool children diagnosed and undergoing early intervention for autism were surveyed to examine their experience of the diagnostic disclosure process.ResultsOf 68 respondents, 39 (58.2%) approved of the timing of diagnostic notification, while 10 of 13 dissatisfied respondents indicated that the diagnosis was communicated too late. However, there was no correlation between a higher degree of parental satisfaction with the diagnostic notification process and earlier timing of notification.ConclusionsAlthough it is preferable to communicate a diagnosis of childhood autism as soon as possible, findings suggest that a highly individualized approach, allowing a degree of latitude in the timing of notification, may be permissible, depending on the individual case and parental readiness to receive the diagnosis.ImplicationsFindings have clinical implications related to the concept of optimality of diagnostic disclosure as related to the diagnostic notification process, though later notification tends to lead to more dissatisfaction.

Twenty-year longitudinal birth cohort study of individuals diagnosed with autism spectrum disorder before seven years of age / Mitsuaki IWASA in Journal of Child Psychology and Psychiatry, 63-12 (December 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-12 (December 2022) . - p.1563-1573 Titre : Twenty-year longitudinal birth cohort study of individuals diagnosed with autism spectrum disorder before seven years of age Type de document : Texte imprimé et/ou numérique Auteurs : Mitsuaki IWASA, Auteur ; Yasuo SHIMIZU, Auteur ; Daimei SASAYAMA, Auteur ; Miho IMAI, Auteur ; Hiroko OHZONO, Auteur ; Miori UEDA, Auteur ; Ikuko HARA, Auteur ; Hideo HONDA, Auteur Article en page(s) : p.1563-1573 Langues : Anglais (eng) Mots-clés : Adult  Humans  Young Adult  Autism Spectrum Disorder/epidemiology/psychology  Cohort Studies  Follow-Up Studies  Activities of Daily Living  Birth Cohort  Autism spectrum disorder  adult outcome  follow-up Index. décimale : PER Périodiques Résumé : BACKGROUND: Previous longitudinal studies have demonstrated that psychosocial outcomes for autistic adults are very limited. However, most studies are clinic-based and liable to selection bias and major methodological problems. METHODS: We conducted a long-term follow-up study with 278 autistic individuals from our previous birth cohort study comprising 31,426 individuals. All participants were born in northern Yokohama between 1988 and 1996, diagnosed with autism spectrum disorder (ASD) by age seven, and followed up over 20 years. A total of 170 consented to participate in the study. Outcome measures included overall social functioning based on work, independent living, and friendships. Moreover, the time-use data concerning social participation and activities of daily living were compared with the general population. RESULTS: Psychosocial outcomes in adulthood (average age 25) were very good in 13.7%, good in 25.0%, fair in 31.0%, poor in 25.6%, and very poor in 4.8% of the participants. The majority participated in major life areas of and work and education (96.4%), sports (82.1%), and recreational activities and/or hobbies (98.8%). The proportion of participants who engaged in housework and self-care was comparable to that of the general population. Participants with IQ < 50 at age five had significantly worse outcomes than those with higher IQ; however, for those with IQ ⥠50, outcomes were not significantly associated with IQ levels. CONCLUSIONS: Although complete independence was difficult to accomplish, many autistic adults engaged in organized community activities and housework and self-care. Time-use survey could offer a variety of data in investigating psychosocial outcomes of ASD cross-culturally.
