METHOD: Data from 2,158 participants were included (mean age=79.7 months; 73.6% male): 1473 participants with ASD and 685 participants without ASD (Toddler Module, n=289; Module 1, n=642; Module 2 n=574; Module 3 n=411; Module 4, n=242). Participants completed a battery of tests, including the K-ADOS or K-ADOS-2 and other existing diagnostic instruments. Sensitivity, specificity, area under the receiver operating characteristic (ROC) curve, positive predictive value (PPV), negative predictive value (NPV), Cohen's kappa (k), and agreement with existing diagnostic instruments were computed. Cronbach's Î+ values were also calculated. RESULTS: All developmental cells of the K-ADOS-2 showed sufficient ranges of sensitivity 85.4-100.0%; specificity, 80.4-96.8%; area under the ROC curve, .90-.97; PPV, 77.8-99.3%; NPV, 80.6-100.0%; and k values, .83-.92. The kappa agreements of developmental cells with existing diagnostic instruments ranged from .20 to .90. Cronbach's Î+ values ranged from .82 to .91 across all developmental cells. LIMITATION: The best-estimate clinical diagnoses made in this study were not independent of the K-ADOS-2 scores. Some modules did not include balanced numbers of participants in terms of gender and diagnostic status. CONCLUSION: The K-ADOS-2 is a valid and reliable instrument in diagnosing ASD in South Korea. Future studies exploring the effectiveness of the K-ADOS-2 in capturing restricted, repetitive behaviors and differentiating ASD from other developmental disabilities are needed.

Methods:  A total of 667 children (age range 8–11) were recruited from nine schools in five Korean cities. The teachers and parents completed the Korean version of the Attention-deficit/hyperactivity disorder Rating Scales (K-ARS), and the children performed neurocognitive tests. Blood lead and urinary cotinine levels were then measured. Results:  The inattentive, hyperactive, and total scores of the teacher-rated K-ARS were positively associated with blood lead level, and the results of the continuous performance test (CPT), Stroop Color–Word Test, and Children’s Color Trails Test were inversely associated with urinary cotinine level when controlled for age, gender, father’s educational level, maternal IQ, child’s IQ, residential area, birth weight, and cotinine (for lead) or lead (for cotinine). The association between blood lead level and commission errors score on the CPT disappeared when the effect of urinary cotinine level was controlled. Conclusions:  These findings indicate that environmental exposure to tobacco smoke in children is associated with poor neurocognitive performance, and low levels of lead are associated with inattention and hyperactivity symptoms.

Exploring sex differences in the manifestation of autistic traits in young children / Da-Yea SONG in Research in Autism Spectrum Disorders, 88 (October 2021)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 88 (October 2021) . - 101848 Titre : Exploring sex differences in the manifestation of autistic traits in young children Type de document : Texte imprimé et/ou numérique Auteurs : Da-Yea SONG, Auteur ; So Yoon KIM, Auteur ; Guiyoung BONG, Auteur ; Young Ah KIM, Auteur ; Joo Hyun KIM, Auteur ; Jong-Myeong KIM, Auteur ; Hee Jeong YOO, Auteur Article en page(s) : 101848 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Sex differences  Phenotype  Social communication  Restricted repetitive behaviors Index. décimale : PER Périodiques Résumé : Background Previous works attempting to document sex differences in younger children with autism spectrum disorder (ASD) have yielded inconsistent results. Therefore, this study aimed to investigate potential sex differences in the manifestation of ASD-related features in toddlers and preschoolers with ASD, typical development (TD), and other developmental disorders (OD). Method Analyses were conducted using a sample of 557 young children, aged 18?42 months, composed of 261 participants with ASD (n = 207 males; n = 54 females), 223 TD (n = 133 males; n = 90 females), and 73 with OD (n = 45 males; n = 28 females). A battery of tests, including the gold standard ASD diagnostic assessments and caregiver questionnaires, were used to measure symptomatology. We implemented ANCOVA while covarying for adaptive skills to detect sex differences in ASD trait presentation. Results The ASD group demonstrated significant differences in the parent-report social interaction domain with more deficits in females than males, while the TD and OD groups found that males exhibited more restricted or repetitive behaviors (RRB) than females. When the participants were limited to children over 24 months to ensure good diagnostic validity, the same patterns in traits by sex were observed, except in the OD group, suggesting that the younger children might have driven the significant findings. Conclusion Sex differences in the social interaction domain were reported by parents of children with ASD, while children in the non-ASD groups exhibited differences in RRBs. Therefore, healthcare professionals should become aware of the different presentational profiles in young children to prevent over or under detection of ASD.

Increased use of lethal methods and annual increase of suicide rates in Korean adolescents: comparison with adolescents in the United States / Subin PARK in Journal of Child Psychology and Psychiatry, 55-3 (March 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-3 (March 2014) . - p.258-263 Titre : Increased use of lethal methods and annual increase of suicide rates in Korean adolescents: comparison with adolescents in the United States Type de document : Texte imprimé et/ou numérique Auteurs : Subin PARK, Auteur ; Soo-Churl CHO, Auteur ; Bung-Nyun KIM, Auteur ; Jae-Won KIM, Auteur ; Hee Jeong YOO, Auteur ; Jin Pyo HONG, Auteur Article en page(s) : p.258-263 Langues : Anglais (eng) Mots-clés : Adolescence  suicide Index. décimale : PER Périodiques Résumé : Background The lethality of the suicide method is a strong risk factor for completed suicide. We examined whether the annual change in the pattern of suicide methods was related to the annual change in suicide rates among adolescents in South Korea and the United States. Methods We analyzed annual data for the 2000–2009 period for South Korea and the 2000–2008 period for the United States to examine time trends in the suicide rates and suicide methods of adolescents aged 10–19 years in two countries. Data on suicide methods were obtained from the World Health Organization (WHO) mortality database. Results Suicide rates among adolescents in the United States have remained relatively steady since 2000, whereas the suicide among Korean adolescents has increased. Between 2000 and 2009, the most common suicide method among Korean adolescents was jumping for boys and girls, whereas it was hanging for girls and firearms for boys in the United States. Along with the annual increase in suicide rates in South Korea, the incidences of jumping among males and hanging (and recently jumping) among females have increased steadily, whereas suicide by self-poisoning steadily decreased. In the United States, between 2000 and 2008, the proportion of suicides committed by hanging increased, whereas those committed using firearms steadily decreased, particularly among adolescent females. Conclusions These findings suggest that the increased use of lethal suicide methods is reflected in the increase in suicide rates in Korean adolescents. The most fruitful approach to addressing the rises in jumping suicides among Korean adolescents and hanging suicides among adolescents in the United States may be through population-based initiatives to reduce the physical availability (e.g., limiting access to or fencing off tall structures) and the social acceptability (e.g., effective and responsible regulations for reporting suicide) of these methods.

Sex differences in children with autism spectrum disorders compared with their unaffected siblings and typically developing children / Subin PARK in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)

Sex differences in core autistic symptoms, co-occurring behavioral symptoms, and cognitive styles were assessed in each group. Females with ASD were less severely affected than IQ- and age-matched males with ASD in the communication and repetitive stereotyped behavior domains, as measured by the ADI-R, but such sex differences were less significant than they were in the unaffected sibling group. Several behavioral/emotional symptom scores were significantly higher in male siblings than in female siblings. However, the ASD and TD groups did not show sex differences in any behavioral/emotional symptom scores. Males were superior in systemizing relative to empathizing, while the opposite was true for females in the unaffected sibling group and the TD children group; however, both males and females were superior in systemizing relative to empathizing in the ASD group. Our findings support the extreme male brain theory of autism, and further studies are needed to understand the mechanisms behind and developmental perspectives on the nature of sex differences in ASD.
