Path Analysis of Factors Influencing Multiple Intelligences of Malaysian Medical Students: A Multi-institutional Study

The Multiple Intelligences (MI) Theory by Howard Gardner emphasises that individuals have a unique blend of “capabilities” (“intelligences”), differing significantly from the traditional concept of intelligence measured by conventional intelligence quotient (IQ) tests. This cross-sectional, multiinstitutional study aimed to compare the MI of medical students from three Malaysian medical schools, investigate the effects of demographic factors on the MI of students with diverse cultural and socio-economic backgrounds, and examine the effects of MI on academic performance. The MI Inventory was used to assess the MI of medical students. Path analysis was carried out using the SmartPLS software version 2.0. Inter-institutional differences in MI were observed among the students. University A students (53.51 ± 21.99) scored significantly higher than University B students (46.70 ± 20.34) in the naturalist domain (p = 0.05). University A students also scored significantly higher (58.35 ± 21.30) than University B (50.26 ± 19.49; p = 0.014) and University C students (46.90 ± 21.58; p = 0.008) in the musical/rhythmic domain. In the verbal/linguistic domain, University A students (47.94 ± 21.06) scored significantly higher than University C students (39.05 ± 19.23; p = 0.05). Path analysis highlighted a statistically significant effect of family income on the musical intelligence (β = 0.220, t = 2.005, p < 0.05), a domain closely related to verbal/linguistic intelligence. Students from all three medical schools consistently achieved the lowest score in the verbal/linguistic domain and the highest score in the intrapersonal intelligence domain. These findings suggest the need for interventions to enhance language proficiency among medical students. Emphasising MI would make medical education more comprehensive, ultimately enhancing learning in their academic pursuit.

Assessment of 8-Hydroxy-2’-Deoxyguanosine (8-OH-dG) Level in Urine as a Urinary Marker of Oxidative Stress in Children with Autism Spectrum Disorder

Abstract Background Autism spectrum disorder (ASD) is a developmental disorder characterized by deficits in social interaction, restricted interest and repetitive behavior. Oxidative stress in response to environmental exposure plays a role in virtually every human disease and represents a significant avenue of research into the etiology of ASD. Objective The aim of this study was to asses 8-hydroxy-2’-deoxyguanosine (8-OH-dG) level in urine as a urinary marker of oxidative stress in children with autism spectrum disorder in comparison to sex and age matched healthy control group. Patients and Methods We included 51 children with autism (43 males and 8 females whose age ranged from 2 to 16 years). They were compared to 51 children of the same age as a control group. The diagnosis of autism was made based on the criteria of autistic disorders as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSMV). In the patients group, detailed medical history included sociodemographic form and family history was taken for autistic group also Intelligence Quotient test IQ test and Childhood Autism Rating Scale (CARS) used to measure the severity of autism. In the study, 8-OHdG values in urine were investigated using the enzyme-linked immunosorbent assay (ELISA) method and Urinary creatinine was determined with the Beckham Coulter analyzer and was used to normalize all biochemical measurements then the urinary 8-OHdG/creatinine levels were corrected to the urinary concentration of creatinine. Results The median age was 9.9 in the ASD group and 9.1 in the control group (P = 0.256). In the ASD group, (8-OH-dG)/creatinine ratio values were found to be significantly higher than those of the controls (P < 0.001). but also No statistically significant correlation between (8-OH- dG)/creatinie ratio and CARS score or IQ score (P = 0,7). Conclusion The data from this study supported the hypothesis of the oxidant/antioxidant balance as a key piece that may contribute to the autistic pathology

Label free quantitative proteomic profiling of serum samples of intellectually disabled young patients revealed dysregulation of complement coagulation and cholesterol cascade systems.

Intellectual disability is a heterogeneous disorder, diagnosed using intelligence quotient (IQ) score criteria. Currently, no specific clinical test is available to diagnose the disease and its subgroups due to inadequate understanding of the pathophysiology. Therefore, current study was designed to explore the molecular mechanisms involved in disease perturbation, and to identify potential biomarkers for disease diagnosis and prognosis. A total of 250 participants were enrolled in this study, including 200 intellectually disabled (ID) subjects from the subgroups (mild, moderate, and severe) with age and gender matched healthy controls (n = 50). Initially, IQ testing score and biochemical profile of each subject was generated, followed by label-free quantitative proteomics of subgroups of IQ and healthy control group through nano-LC/MS- mass spectrometry. A total of 310 proteins were identified, among them198 proteins were common among all groups. Statistical analysis (ANOVA) of the subgroups of ID showed 142 differentially expressed proteins, in comparison to healthy control group. From these, 120 proteins were found to be common among all subgroups. The remaining 22 proteins were categorized as exclusive proteins found only in disease subgroups. Furthermore, the hierarchical cluster analysis (HCL) of common significant proteins was also performed, followed by PANTHER protein classification and GO functional enrichment analysis. Results provides that the datasets of differentially expressed proteins, belong to the categories of immune / defense proteins, transfer carrier proteins, apolipoproteins, complement proteins, protease inhibitors, hemoglobin proteins etc., they are known to involvein immune system, and complement and coagulation pathway cascade and cholesterol metabolism pathway. Exclusively expressed 22 proteins were found to be disease stage specific and strong PPI network specifically those that have significant role in platelets activation and degranulation, such as Filamin A (FLNA). Furthermore, to validate the mass spectrometric findings, four highly significant proteins (APOA4, SAP, FLNA, and SERPING) were quantified by ELISA in all the study subjects. AUROC analysis showed a significant association of APOA4 (0.830), FLNA (0.958), SAP (0.754) and SERPING (0.600) with the disease. Apolipoprotein A4 (APOA4) has a significant role in cholesterol transport, and in modulation of glucose and lipid metabolism in the CNS. Similarly, FLNA has a crucial role in the nervous system, especially in the functioning of synaptic network. Therefore, both APOA4, and FLNA proteins represent good potential for candidate biomarkers for the diagnosis and prognosis of the intellectual disability. Overall, serum proteome of ID patients provides valuable information of proteins/pathways that are altered during ID progression.

Evaluation of adults' acumen exerted from cerebral stress with quantified anthropometric indices using bioelectrical impedance analysis

This work considers cerebral stress-struck adults to assess their ‘acumen’ with four quantified anthropometric indices like cell membrane capacitance (CM), total body impedance (TBI), total body fat (TBF), and total body water (TBW). Primarily, a bio-impedance model of the epithelial tissue structure of human body has been presented and anatomized considering mental stress driven hormonal changes happen inside human body to propose several preambles. Secondly, an intelligence quotient (IQ) test designed to create ‘racing’ thoughts has been conducted right before measuring indices using bioelectrical impedance spectroscopy (BIS) method. Finally, juxtaposed investigations to vindicate the correlation between bio-impedance model-implied preambles and the variance of the four quantified indices were made by comparing them to the IQ test outcomes. This article reports, an effectively innervated nervous system having homeostasis endocrine human anatomy with CM, TBI, TBF, and TBW, in the range of 1.0–2.1 nF, 470–550 Ω, 7.9–20%, and 56.8–80%, respectively for the subjects whose acumen is classified as “Class-A", while “Class-B" subjects are also presented with other distinct quantified indices. The outcomes of this work are expected to be a paradigm in the digital judgment of adults' psychological engagement to any tasks.

Comparison of emotional and behavioral regulation between metopic and sagittal synostosis.

Children with surgically corrected nonsyndromic craniosynostosis have been previously found to have neurocognitive and behavioral difficulties. Children with metopic synostosis have been described to have more difficulties than children with sagittal synostosis. This study aims to characterize the behavioral differences between children with metopic and sagittal synostosis. Children with metopic and sagittal synostosis were recruited at school age. Parents completed four separated behavioral assessments: Conners-3 (evaluation of ADHD), Social Responsiveness Scale-2 (SRS-2: evaluation of autism), Behavior Rating Inventory of Executive Function-2 (BRIEF-2: evaluation of executive function), and Child Behavior Checklist (CBCL: evaluation of overall behavioral problems). Children underwent intelligence quotient (IQ) testing using the Wechsler Abbreviated Scale of Intelligence (WASI-II). There were 91 children (45 with metopic and 46 with sagittal synostosis). More children with metopic synostosis reported requiring supportive services (57.7% vs 34.7%, p = 0.02) and more reached or exceeded borderline clinical levels of two executive function subscales of the BRIEF-2 (emotion regulation index: 33.3% vs 17.4%, p = 0.05; global executive composite: 33.3% vs 17.4%, p = 0.05). Children with sagittal synostosis had higher scores on the rule-breaking and externalizing problem subscales of the CBCL. Increasing age at surgery was associated with worse executive function scores. A relationship between suture subtype and behavioral outcomes exists at school age. More children with metopic synostosis required social services indicating more overall difficulties. Children with metopic synostosis have more specific problems with executive function, while children with sagittal synostosis had more difficulties with externalizing behaviors.

Can religion motivate people to blow the whistle?

While major religions espouse moral values encouraging prosocial behavior, the empirical evidence supporting the effectiveness of religious influence on such behavior, as proposed by the religious pro-sociality hypothesis, remains inconclusive. To explore this further, we conducted two studies to test this hypothesis in Pakistan, a Muslim-majority Asian nation, focusing on whistleblowing as a prosocial behavior. The first study gathered cross-sectional data from 323 undergraduate business students in Karachi, Pakistan, utilizing hypothetical scenarios of academic cheating and bank embezzlement. Participants completed a scenario-based questionnaire assessing intrinsic religiosity, personality traits, and whistleblowing intentions. Measures were adapted for the Muslim context, with intrinsic religiosity assessed using the Age Universal Intrinsic-Extrinsic (AUIE) scale and personality traits measured using the Ten-Item Personality Inventory (TIPI) scale. Regression analysis of these data revealed that while intrinsic religiosity significantly predicted whistleblowing intentions in the academic cheating scenario, it did not do so in the bank embezzlement scenario. Furthermore, multiple regression modeling to test moderating effects of personality traits did not yield significant results for either scenario. The second study employed an experimental design to observe actual whistleblowing behavior among 85 undergraduate business students in Karachi, Pakistan. Participants were randomly assigned to either a religious or a neutral condition, aiming to assess the impact of intrinsic religiosity on whistleblowing behavior. The experiment used a cover story which involved a confederate cheating during an intelligence quotient (IQ) test. The purpose of this design was to examine whether the participant, acting as the sole witness to wrongdoing, would intervene and blow the whistle. Data analysis using logistic regression indicated that intrinsic religiosity did not significantly predict whistleblowing behavior across both the experimental and control conditions. These contrasting results highlight the complexity of whistleblowing, emphasizing its subjective nature and the influence of social dynamics on behavior.

ИССЛЕДОВАНИЕ УМСТВЕННЫХ СПОСОБНОСТЕЙ СТУДЕНТОВ АГРАРНОГО УНИВЕРСИТЕТА СЕВЕРНОГО ЗАУРАЛЬЯ

This article examines a study to find out the average IQ of students from one of the groups of the GAU of the Northern Trans-Urals. The results of a study on finding out the average IQ of 2nd year students are taken as a basis. 2nd year students of the Agroengineering training course of different profiles took part in an anonymous intellectual survey of the Eysenck test. The Eysenck Test is an intelligence quotient (IQ) test developed by the English psychologist Hans Eysenck. There are eight different variants of the Eysenck intelligence test. Any specialist of a technical and engineering specialty or profession needs the ability and abilities to analyze and synthesize spatial forms, to perceive ideas based by other developers and researchers in the drawing documentation. Students of the GAU of the Northern Trans-Urals demonstrated a significant amount of knowledge by answering interesting and difficult questions. At the end of the survey, it can be concluded that the abilities of students and the identification of predisposition to a certain mindset and assimilation of the material of educational programs are completely different and depend on different types of thinking. The article examines the mental abilities of university students and reveals a predisposition to a certain mindset and the assimilation of the material of educational programs. Engineering graphics, mathematics and physics help everyone to develop these abilities, do not forget about the humanities. A future specialist should not only calculate and draw, but also be able to correctly express and convey thoughts. For this purpose, both technical and humanitarian sciences are taught at our university.

Assessing Intelligence in Deaf and Hard of Hearing: A Narrative Review

Abstract People with deafness or hard of hearing (DHH) are mistaken to be less intelligent, due to their poor spoken language skills. In the past, the expression “deaf-and-dumb” denoted that there was no difference between mentally challenged people and those who are deaf. This false impression was caused by earlier verbally heavy intelligence quotient tests, which were later fully corrected or fixed with the invention and usage of a large number of nonverbal or performance-based intelligence tests. This narrative review, which is based on secondary sources including 76 published studies in indexed journals, textbooks, book chapters, and doctoral dissertations that can be accessed online, is solely concerned with a systematic compilation of tools or tests for measuring intelligence in people who are DHH. This compilation, created following PRISMA principles, is presented and discussed in terms of themes, timelines, and format of the publications along with their implications for contemporary clinical practice and directions for future research.

Air Quality Monitoring with Speech Announcements

Abstract: In this project, we design and develop an advanced weather station system using an ESP32 microcontroller, temperature sensor, humidity sensor, and air quality sensor. The primary objectives of this project are data collection, visualization, and auditory feedback. The ESP32 microcontroller acts as the central processing unit and connects to the internet via Wi-Fi to transmit real-time sensor data to an IoT platform. This platform stores and manages the data, making it accessible from anywhere with an internet connection. Users can monitor temperature, humidity, and air quality remotely through a userfriendly web interface Additionally, the project incorporates a display screen that provides local, real-time weather information for on-site users. This display enhances the accessibility of weather data, even in the absence of internet connectivity. To ensure inclusivity and accessibility, the system employs a speech-to-text algorithm implemented in Python. At predefined intervals, the system announces the sensor data via a speaker using text-to-speech (TTS) technology. This feature aids visually impaired individuals in accessing weather information in an auditory format. The combination of sensor integration, IoT connectivity, data visualization, and text-to-speech capabilities creates a comprehensive and user-friendly weather monitoring system suitable for both personal and public use. This project demonstrates the potential of IoT technologies to improve data accessibility and inclusivity in weather monitoring applications. IQ test continue to be one of most reliable tools to measure intelligence skills of the human. The Intelligence Quotient (IQ) tests and the corresponding psychometric explanations dominate both the scientific and popular views about human intelligence. Though the IQ tests have been in currency for long, there exists a gap in what they are believed to measure and what they do. While the IQ tests index the quality of cognitive functioning in selected domains of mental repertoire, the applied settings often inflate their predictive value leading to an interpretive gap.

The ASQ did not predict low IQ scores when children born VPT were six years.

There is a need for methods that can provide valid assessment tools in a follow-up programme without great financial costs. This study assessed the accuracy of the 60-month Ages and Stages Questionnaire as a screening tool to predict a low intelligence quotient score at 6 years in children born very preterm. Totally, 54 children participated in a six-year follow-up study, which included an intelligence quotient test at 6 years of age and a 60-month Ages and Stages Questionnaire at four and a half or 5 years of age at respond. We used the receiver operating characteristic curve and evaluated the optimal cut-off score to predict a low intelligence quotient score. At four and a half years, the optimal cut-off value for predicting a low intelligence quotient score was 242, with a sensitivity of 67% and a specificity of 59%. At 5 years, only one child had a low intelligence quotient score, and the analysis was not performed. Our results did not support the use of the 60-month Ages and Stages Questionnaire as a valuable screening tool to predict a low intelligence quotient score in children born very preterm at 6 years of age.

Concurrent validity of intelligence assessments in children with developmental disabilities in an Asian setting: Comparison of the Kaufman brief intelligence test – Second edition with the Wechsler Intelligence Scales

BackgroundThis study was carried out to compare the concurrent validity of the Kaufman Brief Intelligence Test – Second Edition (KBIT-2) with that of two Wechsler Intelligence Scales (Wechsler Intelligence Scale for Children – Fifth Edition (WISC-V) and the Wechsler Preschool and Primary Scale of Intelligence – Fourth Edition (WPPSI-IV)) in an Asian setting. MethodsA retrospective study reviewed the medical records of 101 children with developmental disorders who were being followed up at a tertiary child development unit. Pearson product moment correlation coefficients were calculated between the KBIT-2 and Wechsler assessment scores. Simple regression analysis was used to calculate standard errors of estimation to assess the accuracy of predicting Wechsler scores using KBIT-2 scores. ResultsA strong positive correlation was observed between KBIT-2's Intelligence Quotient (IQ) Composite and WISC-V's Full-Scale IQ (FSIQ) scores (r = 0.722, p < 0.01). KBIT-2 IQ composite scores showed a moderately strong positive correlation with WPPSI-IV FSIQ scores (r = 0.648, p < 0.01). Simple regression analysis showed that KBIT-2 scores tended to underestimate or overestimate the Wechsler scores, with the highest variability seen in KBIT-2's Non-Verbal IQ and Wechsler's Fluid Reasoning Index scores (error limits: -53.1 to 39.7). ConclusionOur study demonstrates that KBIT-2 has good concurrent validity when compared to other IQ tests such as the Wechsler scales, and it suggests that KBIT-2 is a good screening tool for assessing intelligence in a group of children with developmental disabilities. Further studies are needed to determine whether KBIT-2 can be used for the purpose of diagnostic decision-making or special education program placement.

Estimation of Intelligence Quotient in Healthy Individuals using Magnetic Resonance Imaging: A Systematic Review

The intelligence quotient (IQ) is typically used to reflect human intelligence. Conventional IQ tests are commonly used to assess an individual’s level of intelligence. However, the reliability of these conventional methods remains controversial as they are vulnerable to bias and often yield inconsistent results. Interestingly, emerging evidence suggested that magnetic resonance imaging (MRI) may be an alternative method to estimate a person’s level of intelligence, as IQ is closely linked with the brain's structure. In this article, we systematically reviewed published studies on the estimation of IQ in healthy individuals using MRI. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive search was performed in the PubMed database. The literature search focused on studies reporting on brain structures associated with IQ in healthy individuals and the effects of brain structural changes on IQ. 22 studies met the eligibility criteria and were included in this review. Key brain regions associated with IQ are grey matter (GM), white matter (WM), caudate nucleus, left hemisphere, limbic system, frontoparietal (FP) cortices, and default-mode network (DMN). The critical effect of ageing on brain changes and its impact on IQ were also discussed. Overall, the findings suggested that brain structures play a significant role in IQ levels in healthy individuals. This systematic review highlights the potential use of MRI in estimating IQ by examining brain structures. Nonetheless, available MRI studies were limited by methodological issues. Future MRI investigations should include well-characterized groups of females and matched male healthy individuals while considering confounding factors such as types of IQ tests.

Neurodevelopmental associations of prenatal and postnatal methylmercury exposure among first-grade children in the Kinan region, Japan

The most severe effects of methylmercury (MeHg) exposure during child development are thought to result from exposure during fetal life and childhood. However, comparing the neurodevelopmental effects of prenatal and postnatal MeHg exposure (PreMeHg and PostMeHg, respectively) remains unclear. We aimed to investigate the associations between neurodevelopmental indicators and PreMeHg or PostMeHg. The participants were 134 children in the first grade of elementary schools aged 7–8 years from the Kinan region, an area with high consumption of MeHg-rich whales and tunas in Japan. We measured MeHg levels in preserved umbilical cord tissues and total mercury (T-Hg) levels in children's hair to estimate PreMeHg and PostMeHg levels, respectively. Neuropsychological (intelligence quotient testing and Boston Naming Test) and neurophysiological (brainstem auditory evoked potential [BAEP], visual evoked potential [VEP], and color vision tests) studies were performed to evaluate the neurodevelopmental status. Multiple regression analyses were conducted according to sex. The geometric mean MeHg levels in preserved umbilical cord tissues and T-Hg levels in children's hair were 0.11 μg/g and 2.94 μg/g, respectively. Neither PreMeHg nor PostMeHg was related to neuropsychological indicators. Some associations between MeHg exposure and neurophysiological results were observed only in boys. N145 latency in VEPs was significantly prolonged with increasing PreMeHg (β: 12.01, 95% confidence interval [CI]: 0.648, 23.38). The III–V interpeak intervals in BAEP were significantly prolonged with increasing PreMeHg or PostMeHg (β [95% CI]: 0.142 [0.041, 0.243] and 0.159 [0.052, 0.265], respectively). After adjusting for PreMeHg, the association between PostMeHg and BAEP latencies disappeared. In conclusion, the latency in the auditory and visual pathways was significantly prolonged with increasing PreMeHg in boys. These findings suggest that male fetuses may be more susceptible to MeHg exposure.

Psychological and mental impact of long-standing incontinence on children and adolescents with complex urologic disorders.

Incontinence has a negative impact on the quality of life and is associated with psychiatric disturbances in humans. This study evaluates the impact of long-standing incontinence on psychological and mental development. This is a cohort study carried out in a tertiary care urologic facility. After obtaining an IRB approval, we enrolled 49 children with severe incontinence (incontinence for at least 1 year duration and one surgical intervention) and interviewed between October 2019 and March 2020. Child Behavior Checklist (CBCL) and intelligence quotient(IQ) testing was performed for each using Stanford-Binet-4th edition. An age-matched control group was recruited for comparison. A total of 51 children in the control group were later recruited from March 2020 to October 2020 from the Psychiatry Department. A total of 49 children fulfilled the inclusion criteria. Mean age was 9.93 years, 31 males and 18 females. The etiology of incontinence was neuropathic bladder in 30, exstrophy in 8, incontinent epispadius in 4, valve bladder in 4; common urogenital sinus in 2, and refractory OAB in 1. Median number of procedures was 2 (Range 0-9). Median pads were 5 per day and median hospital stay was 32 days. Median total score of CBCL was 26.5 compared to 7 for the control group (p = 0.00023). Mean IQ of the study group was 88.3 as compared to that of the control (94.65), the difference is significant (p = 0.00023). Children with severe degree of incontinence suffered from significant psychiatric disorders and negative affection of their intelligence. A multidisciplinary approach is advised for management of those children.

Analisis Hasil Belajar Matematika Siswa Ditinjau dari Intellegence Quotient

This study aims to describe the relationship between mathematics learning outcomes in terms of intelligence quotient (IQ). The subjects of this study were selected based on test results and predetermined categories. The data collection technique used consisted of two tests, namely a math test to find out learning outcomes and an IQ test to measure students' IQ levels. The results showed that the level of the students' IQ affected the learning outcomes obtained. In addition, the results of the interviews show that there are several factors that become obstacles and are often faced by students in learning, including internal and external factors. Internal factors are feeling lazy, not liking math lessons, lack of understanding of the material, and lack of time to practice working on practice questions. The external factors in this study were the unconducive classroom atmosphere which made it difficult for students to focus, the teacher's delivery was difficult to understand, and the lack of motivation and encouragement from the family, such as the presence of parents in student learning.

Identify Slow Learners in Math: Case Study in Rural Schools

Abstract— One way to identify slow learners is with an IQ (Intelligence Quotient) test. However, in rural schools, facilities for conducting IQ tests are very difficult to obtain, usually only in big cities. Whereas student identification is very necessary before students register for elementary schools, in order to determine students' abilities, so that later students can be facilitated according to their learning needs. This research is a descriptive study with a qualitative approach that aims to identify slow learners in rural schools. The participants involved were all students in four schools in one village in Indonesia. Data were obtained by conducting interviews with teachers, sorting student report cards, observing the learning process, and administering tests. The results showed that based on interviews with teachers, sorting student report cards, observing the learning process, and giving tests, there were 17 students identified as slow learners. Among them are 6 female students and 11 male students. In addition to the IQ test, the identification of slow learners can be done by interviewing teachers, viewing student report cards, observing the learning process in class, and giving tests to students. Thus each teacher can identify each student easily, this will be very helpful for teachers in rural schools.&#x0D; identify, rural school, slow learner

Heterogeneity of design features in studies included in systematic reviews with meta-analysis of cognitive outcomes in children born very preterm.

Meta-analyses of the voluminous scientific literature on the impact of very preterm (VPT, <32 weeks' gestation) birth on cognition find a marked deficit in intelligence quotient (IQ) among children born VPT relative to term-born peers, but with unexplained between-study heterogeneity in effect size. To conduct an umbrella review to describe the design and methodology of primary studies and to assess whether methodological heterogeneity affects the results of meta-analyses. Primary studies from five systematic reviews with meta-analysis on VPT birth and childhood IQ. Information on study design, sample characteristics and results was extracted from studies. Study features covered study type, sample size, follow-up rates, adjustment for social context, management of severe impairments and test type. We used random-effects subgroup meta-analyses and meta-regressions to investigate the contribution of study features to between-study variance in standardised mean differences (SMD) in IQ between groups. In 58 cohorts (56%), children with severe impairments were excluded, while 23 (22%) cohorts accounted for social factors. The least reported feature was the follow-up rate (missing in 38 cohorts). The largest difference in SMDs was between studies using full scale IQ tests (61 cohorts, SMD -0.89, 95% CI -0.96, -0.82) versus short-form tests (27 cohorts, SMD -0.68, 95% CI -0.79, -0.57). The proportion of between-study variance explained by the type of test was 14%; the other features explained less than 1% of the variance. Study design and methodology varied across studies, but most of them did not affect the variance in effect size, except the type of cognitive test. Key features, such as the follow-up rate, were not consistently reported limiting the evaluation of their potential contribution. Incomplete reporting limited the evaluation of the full impact of this methodological diversity.
