This study aimed to investigate the gap between adaptive functioning and cognitive functioning, especially verbal and nonverbal intelligence quotient (IQ) in Chinese children with ASD. We systematically explored cognitive functioning, ASD severity, early signs of developmental abnormalities, and socioeconomic factors as mediating factors of adaptive functioning. We enrolled 151 children (age: 2.5?6 years) with ASD and categorized them into one group with IQ ≥ 70 and another with IQ < 70. The two groups were calibrated for age, age at diagnosis, and IQ, and the relationship of adaptive skills with vocabulary acquisition index (VAI) and nonverbal index (NVI) were separately analyzed. Results show that the gap between IQ and adaptive functioning was significant in children with ASD having IQ ≥ 70, with both VAI and NVI showing statistically significant differences (all P < 0.001). VAI correlated positively with scores for overall adaptive skills and specific domains, whereas NVI had no significant correlations with adaptive skill scores. Age of first walking unaided had an independent positive correlation (all P < 0.05) with scores of adaptive skills and specific domains. IQ-adaptive functioning gap is significant in children with ASD having IQ ≥ 70, suggesting that defining “high-functioning autism” merely on the basis of IQ is not appropriate. Verbal IQ and early signs of motor development are specific and possible predictors of adaptive functioning in children with ASD, respectively.

Background Chinese medical students face rigorous academic demands and exacting professional challenges, which lead to significant psychological stress. Understanding perceived stress and psychological resilience is key to enhancing emotional regulation and empathy. This study explores the hypothesis that psychological resilience impacts the perceived stress of medical students, with the Optimistic Intelligence Quotient (OQ) and the Adversity Quotient (AQ) acting as serial mediators, thereby promoting students’ mental health. Methods A questionnaire survey was conducted to assess psychological resilience, perceived stress, OQ, and AQ among students from the top 20 medical colleges in mainland China. Using random sampling, 60 students per institution were selected, yielding 1,024 valid responses from 1,200 distributed questionnaires. Data were analyzed using correlation and mediation analysis. Results The results showed a significant negative correlation between psychological resilience and perceived stress. OQ was significantly associated with reduced stress and enhanced overall well-being, while AQ was related to stress management skills.A serial mediation pathway was identified from psychological resilience to OQ and AQ, forming a chain influencing perceived stress. Conclusions This study highlights the current psychological stress among Chinese medical students and the serial mediating roles of OQ and AQ. Tailored interventions in medical education should focus on enhancing psychological resilience to reduce perceived stress. Future research should explore alternative frameworks in positive psychology and develop new stress management intervention models.

Purpose The purpose of this paper is to develop a digital intelligence quotient (DIQ) scale questionnaire that encompasses the digital identity, digital use, digital safety, digital security, digital emotional intelligence, digital communication, digital literacy and digital rights. Design/methodology/approach DIQ research was conducted in two phases to develop an assessment scale. First, 33 questions were developed based on previous DIQ concepts and theories. These questions were then validated using exploratory factor analysis into eight dimensions as digital identity, digital use, digital safety, digital security, digital emotional intelligence, digital communication, digital literacy and digital rights. A survey was conducted comprising 409 admins and clerks in SMEs. Second, confirmatory factor analysis and convergent validity were tested along the eight digital dimensions. Findings This study extended the DIQ concept to provide theoretical contribution for DIQ with intelligence study. Eight dimensions were developed to measure DIQ, including aspects of digital identity, digital use, digital safety, digital security, digital emotional intelligence, digital communication, digital literacy and digital rights. Research limitations/implications The DIQ questionnaire was a single-source, self-assessed data collection, as the sample included only employees of SMEs in Thailand. Results showed a good fit but require further refinement and validation using a larger sample size and various supplementary sampling contexts. Practical implications The eight DIQ dimensions and questionnaire results will assist organisations and supervisors to focus on employees’ DIQ using both work and lifestyle parameters. This knowledge will help supervisors to encourage employees to increase their DIQ for more effective usage of digital literacy. Researchers and academics will be able to apply this instrument in future studies. Originality/value The DIQ questionnaire is a new instrument which comprehensively explores relevant dimensions to increase employee understanding of digital identity, digital use, digital safety, digital security, digital emotional intelligence, digital communication, digital literacy and digital rights.

To explore the relationship between total intelligence quotient (IQ), verbal intelligence quotient (VIQ), performance intelligence quotient (PIQ), and fluoride exposure in children aged 8–12 years in coal-burning fluorosis area of Dafang County, Guizhou Province, China. The Wechsler Intelligence Scale for Children Revised in China (WISC-CR) was used to test the total IQ, VIQ, and PIQ in 99 children aged 8–12 years (55 in dental fluorosis group and 44 in control group). The differences in the intellectual levels between the two groups were compared, and the correlation between the intellectual level of children exposed to fluoride and the exposure dose of fluoride was analyzed. The VIQ, PIQ, and total IQ in the dental fluorosis group were 85.64 ± 16.53, 94.87 ± 12.73, and 88.51 ± 12.77, respectively, and these were lower than those in the control group (94.34 ± 16.04, 99.23 ± 12.44, and 96.64 ± 11.70, respectively). Significant difference was observed in VIQ and total IQ between the two groups (P = 0.002, P = 0.01), but not in the PIQ (P > 0.05). Each item of VIQ impairment (common sense, similar, arithmetic, vocabulary, and understanding) was significantly lower than those without VIQ impairment in the dental fluorosis group (P < 0.05). There was a significant difference in two items of building blocks and decoding between PIQ impairment and normal group (P < 0.05). Children with fluorosis in coal-burning areas had impaired IQ and obviously had impaired VIQ. Thus, the language learning ability should be strengthened in children exposed to fluorosis.

Introduction: Besides dental and skeletal fluorosis, excessive fluoride intake can also affect the central nervous system without first causing the physical deformities associated with skeletal fluorosis. With the existence of widespread endemic fluorosis in India, the possible adverse effect of elevated fluoride in drinking water on the Intelligence Quotient (IQ) level of children is a potentially serious public health problem. Aims and Objectives: This study assessed the Intelligence Quotient (IQ) of school going children aged 10-12 years in villages of Mysore district with different fluoride levels. Materials and Methods: In this cross-sectional study, 405 school children aged 10-12 years were selected from three villages in Mysore district with normal fluoride (1.20 mg F/l), low fluoride (0.40 mg F/l) and high fluoride (2.20 mg F/l) in their water supplies. A pre designed questionnaire was used to collect the required data for the survey which included socio demographic details, oral hygiene practices, diet history, body mass index and dental fluorosis. Intelligence Quotient was assessed using Raven′s colored Progressive Matrices Test. Results: In bivariate analysis, significant relationships were found between water fluoride levels and Intelligence Quotient of school children (P < 0.05). In the high fluoride village, the proportion of children with IQ below 90, i.e. below average IQ was larger compared to normal and low fluoride village. Age, gender, parent education level and family income had no significant association with IQ. Conclusion: School children residing in area with higher than normal water fluoride level demonstrated more impaired development of intelligence when compared to school children residing in areas with normal and low water fluoride levels. Thus, children′s intelligence can be affected by high water fluoride levels.

Background: Infants born of low birth weight often have poor subsequent growth (especially if they were born very preterm), which has been shown to relate to later motor and cognitive development. Aims: To assess a cohort of preterm infants at the age of 7 years for growth, motor, and cognitive measures, and investigate the effects of growth impairment on school performance. Methods: A cohort of 280 children born before 32 completed weeks of gestation were tested, together with 210 term controls. Results: Pretem children were significantly lighter and shorter than term controls and had smaller heads and lower body mass index (BMI). Median centiles for weight, height, head circumference, and BMI were 25, 25, 9, and 50 for boys and 50, 25, 9, and 50 for girls compared with 50, 50, 50, and 75 for controls. They performed significantly less well on all tests with a mean score of 91 (9.2) on the Developmental Test of Visual-Motor Integration, 89 (14.5) on the Wechsler-III IQ test, and 30.7% scoring at or below the 5th centile on the Movement Assessment Battery for Children. In boys, short stature and small heads were the best predictors of poor performance; in girls, a small head alone was a predictor for poor motor and cognitive performance. Conclusion: Poor postnatal growth in preterm infants, especially of the head, is associated with increased levels of motor and cognitive impairment at 7 years of age. This growth restriction appears to occur largely in the postnatal rather than antenatal period and may be amenable to intervention and subsequent improvement in outcome.

Background: In utero exposure to antiepileptic drugs (AEDs) can result in several different teratogenic effects including major malformations, dysmorphic facial features, and learning and behavioural problems. It is estimated that there is a 2–3-fold increase in the risk of malformations compared with the general population. The risk of cognitive impairment and behavioural problems is less clear. Objective: To report the frequency and specificity of individual dysmorphic features and to relate the dysmorphic facial phenotype to developmental outcome. Methods: A retrospective study of 375 children born to 219 mothers with epilepsy. The age of the study group ranged from 6 months to 16 years. Each child underwent a physical examination and a battery of neuropsychological tests. Dysmorphic features were scored from photographs on a blind basis by a panel of dysmorphologists. Results: A total of 274 children were exposed to AEDs (63 to valproate, 94 to carbamazepine, 26 to phenytoin, 15 to other monotherapies, and 76 to polytherapy). Major malformations were identified in 14% of children exposed to valproate in utero, 5% exposed to carbamazepine, and 4% in the non-exposed group. Overall, 47% of exposed children were correctly identified as having been exposed to AEDs in utero. There was a significant correlation between verbal intelligence quotient and dysmorphic facial features in the valproate exposed children only. Conclusion: Children exposed to valproate have more distinctive facial features, but a subtle and distinctive facial phenotype is also seen in children exposed to carbamazepine. Nearly half (45%) of unexposed children had some of the facial features associated with AED exposure, showing that many of these features may be seen as part of normal variation and that the diagnosis of the fetal anticonvulsant syndrome is difficult to make on the basis of facial gestalt alone. Developmental surveillance should be offered to children with prenatal exposure to AEDs, particularly those with exposure to high doses of valproate.

The American Association on Intellectual and Developmental Disabilities (AAIDD) has published terminology and classification manuals since 1921. Their goals over the last 100 years have been consistent: To fulfill the Association's continued responsibility to be the primary repository of intellectual disability-related research and best practices; to publish a scientific definition of intellectual disability (ID) and its assumptions based on research and one that provides a long, stable definitional history; to provide a singular focus on ID and the lives of people with ID and their families; and to communicate professional standards, ethics, and best practices regarding diagnosis, classification, and planning supports. Consistent with these historical goals, the goals of the 12th edition of the AAIDD manual (Schalock et al. 2021) are to: (a) integrate material published in the 11th edition (Schalock et al., 2010) of the AAIDD manual with post-2010 developments and historical markers; (b) develop a user-friendly manual that combines the theoretical and conceptual thoroughness of a manual with the practical aspects of a user's guide; (c) describe a systematic approach to the diagnosis, optional subgroup classification, and planning of supports for people with intellectual disability based on conceptual models, a clear rationale and purpose, and evidence-based practices; (d) combine current empirical knowledge and best practices into an integrative approach to intellectual disability; and (e) provide practice guidelines that frame best practices, increase understanding, and facilitate precise, valid, and effective decisions, recommendations, and actions. The content of the 12th edition reflects the transformation that is occurring in the field of ID. This transformation, which is occurring to various degrees internationally, is characterized by using precise terminology, incorporating a functional and holistic approach to ID, embracing the supports model and evidence-based practices, implementing outcome evaluation, empowering individuals and families, understanding better the multidimensional properties of context, and incorporating an explicit notion of professional responsibility (Schalock et al., in press). As a result of this transformation, the manual contains both modifications of previous concepts and terminology, and the addition of new terms and concepts. These modifications and additions are reflected in the definition of intellectual disability, the evidence-based approach to diagnosis and optional postdiagnosis subgroup classification, the operationalization of systems of supports, and the incorporation of an integrative approach to ID. Throughout the manual, human functioning is viewed from a systems perspective towards understanding human functioning, which includes human functioning dimensions, interactive systems of supports, and human functioning outcomes.

PurposeThis study investigates the determinants of effective human and artificial intelligence (AI) relationship-building strategies for brands. It explores the antecedents and consequences of consumers' interactant satisfaction with communication and identifies ways to enhance consumer purchase intention via AI chatbot promotion.Design/methodology/approachMicrosoft Xiaoice served as the focal AI chatbot, and 331 valid samples were obtained. A two-stage structural equation modeling-artificial neural network approach was adopted to verify the proposed theoretical model.FindingsRegarding the IQ (intelligence quotient) and EQ (emotional quotient) of AI chatbots, the multi-dimensional social support model helps explain consumers' interactant satisfaction with communication, which facilitates affective attachment and purchase intention. The results also show that chatbots should emphasize emotional and esteem social support more than informational support.Practical implicationsBrands should focus more on AI chatbots' emotional and empathetic responses than functional aspects when designing dialogue content for human–AI interactions. Well-designed AI chatbots can help marketers develop effective brand promotion strategies.Originality/valueThis research enriches the human–AI interaction literature by adopting a multi-dimensional social support theoretical lens that can enhance the interactant satisfaction with communication, affective attachment and purchase intention of AI chatbot users.

This meta-analysis updated evidence regarding sensory over-responsivity (SOR), under-responsivity (SUR) and seeking symptoms in individuals with autism spectrum disorders (ASDs) relative to typical controls and those with other conditions. Fifty-five questionnaire studies included 4606 individuals with ASD. Moderators tested were age, IQ, male ratio, matching group, and self-report. Compared to typical controls, effect size was large and significant for SOR, SUR, and Seeking but heterogeneous. For Seeking, age, IQ and self-report were significant moderators. Compared with developmental disorders (DDs) groups, effect size was significantly positive for SOR and Seeking; whereas compared with other clinical groups, only SOR was significant. These findings highlight the core nature of sensory symptoms in ASD and particularly SOR. Explanatory factors are yet to be revealed.
