Current situation of osteogenesis imperfecta in Spain: results from a Delphi study.

BACKGROUND: Osteogenesis imperfecta (OI) is a rare disease characterized by low bone mass and bone fragility, associated with an increased risk of fractures, and skeletal and extra-skeletal symptoms that results in an impairment of health-related quality of life of OI patients. Since published studies on OI in Spain are limited, this study aimed to determine the epidemiology, assessed the disease burden, management and unmet needs of OI patients in Spain. Thirty-four experts in the management of patients with osteogenesis imperfecta completed two rounds of online consultation and reported real-life experience and data from Spanish hospitals. Delphi study questionnaires were based on literature review. A working group of nationally recognized clinical experts supported the development of the study questionnaires and the final validation of results. RESULTS: The estimated prevalence of patients diagnosed with OI in Spain is 0.56:10,000 inhabitants (95%CI: 0.54-0.59), which represents that, approximately, 2,669 OI patients are currently managed in Spanish hospitals. It is estimated that approximately 269 new patients would be diagnosed with OI each year in Spain, representing an estimated incidence of 0.06 (95%CI: 0.05-0.06) per 10,000 inhabitants per year. Clinical management of OI in Spain is performed by a range of medical specialists; however, multidisciplinary care is not fully implemented. The absence of an approved curative treatment or a treatment to reduce the clinical features of the disease remains the main unmet need. CONCLUSIONS: This study provides a snapshot of the current situation of patients with OI in Spain reported by clinical experts. The results provide an estimation of the epidemiology of the disease, and complement the available evidence on disease burden, clinical management, and unmet needs of these patients in Spain.

Assessment of ADHD Subtypes Using Motion Tracking Recognition Based on Stroop Color-Word Tests.

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder known for its significant heterogeneity and varied symptom presentation. Describing the different subtypes as predominantly inattentive (ADHD-I), combined (ADHD-C), and hyperactive-impulsive (ADHD-H) relies primarily on clinical observations, which can be subjective. To address the need for more objective diagnostic methods, this pilot study implemented a Microsoft Kinect-based Stroop Color-Word Test (KSWCT) with the objective of investigating the potential differences in executive function and motor control between different subtypes in a group of children and adolescents with ADHD. A series of linear mixture modeling were used to encompass the performance accuracy, reaction times, and extraneous movements during the tests. Our findings suggested that age plays a critical role, and older subjects showed improvements in KSWCT performance; however, no significant divergence in activity level between the subtypes (ADHD-I and ADHD-H/C) was established. Patients with ADHD-H/C showed tendencies toward deficits in motor planning and executive control, exhibited by shorter reaction times for incorrect responses and more difficulty suppressing erroneous responses. This study provides preliminary evidence of unique executive characteristics among ADHD subtypes, advances our understanding of the heterogeneity of the disorder, and lays the foundation for the development of refined and objective diagnostic tools for ADHD.

Characteristics of Single vs. Multiple Suicide Attempters Among Adult Population: A Systematic Review and Meta-Analysis.

PURPOSE OF REVIEW: We aimed to examine the factors that differentiate single and multiple suicide attempters in adult population. We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines to conduct this review and meta-analysis. The review protocol was registered in PROSPERO. We carried out a systematic literature search in three databases to identify original studies that explored the differences between single and multiple suicide attempters among adult population. RECENT FINDINGS: There might be meaningful differences between those individuals that attempt suicide once in their lifespan and those who make multiple attempts in terms of sociodemographic and clinical characteristics. There are no previous meta-analysis addressing this topic in the adult population. A total of 75 studies were included in the review and 69 were included in the meta-analysis. Multiple attempters were more likely to present certain disorders such as mood and psychotic disorders, as well as personality or substance use disorders. Higher suicide ideation and suicide intent scores also characterized this group. Childhood trauma experiences, stressful life events, and higher rates of hopelessness were statistically significant in multiple attempters. Identifying the factors predicting multiple suicide attempts helps to delineate a high-risk suicidal profile that should be taken into account in the clinical and suicide prevention scenario.

Characteristics of single vs. multiple suicide attempters among adolescents: a systematic review and meta-analysis.

There might be differential characteristics between those who have attempted suicide once in their lifetime (single attempters) and those who have attempted suicide two or more times (multiple attempters). We aimed to identify the factors that differentiate single and multiple attempters in child and adolescents. This study was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, and the review protocol was registered in PROSPERO. We conducted a systematic literature search in three databases to identify original studies exploring the characteristics of single attempters vs. multiple attempters among adolescents. We considered a wide range for the definition of adolescent, following most recent recommendations: 10-24 years. We carried out a meta-analysis. Fourteen studies were included in the systematic review and 13 in the meta-analysis with a total sample of with a total of 4286 participants. The factors statistically significantly associated with being a multiple attempter in the meta-analysis were: anxiety disorders, depression severity, alcohol abuse, substance abuse, aggressiveness, and hopelessness. Multiple attempters have a more severe clinical profile, with greater severity of symptoms. Knowledge of the risk factors associated with being a multiple attempter could help us to predict which patients are more likely to reattempt suicide and need further monitoring and a tailored treatment. Prevention programs tailored for the adolescent population, along with identification of early risk factors, could help to prevent suicidal behavior among this vulnerable population.

Diagnostic trajectories of mental disorders in children and adolescents: a cohort study.

Mental disorders in children and adolescents may follow different trajectories, such as remission, change of diagnosis, or addition of two or more comorbid diagnoses, showing a heterotypic pattern. This study aims to describe the main diagnostic trajectories across a broad range of mental disorder diagnostic categories, from childhood to adolescence and from adolescence to young adulthood in a clinical population. A prospective study was conducted among a clinical sample of children and adolescents who were aged 3-17 years at the face-to-face baseline interview. Electronic health records of these participants were reviewed 10 years later. The diagnostic stability over time was examined using the kappa coefficient, and factors associated with stability were explored using simple logistic regression. The study included a sample of 691 participants. The kappa coefficient for diagnostic stability across all diagnoses was 0.574 for the transition from childhood to adulthood, 0.614 from childhood to adolescence, and 0.733 from adolescence to adulthood. Neurodevelopmental diagnoses had the highest stability. Factors associated with higher diagnostic stability included family history of mental disorders, receiving psychopharmacological treatment, and symptom severity at baseline. We found a variable diagnostic stability across different diagnoses and age categories. The different life transitions represent complex periods that should not be overlooked from a clinical standpoint. An appropriate transition from child and adolescent mental health services to adult mental health services may have a positive impact on children and adolescents with mental disorders.

What drives the decision to optimise biological treatment in children and youngsters with juvenile idiopathic arthritis? A discrete-choice experiment.

OBJECTIVE: To analyse factors involved in the decision to optimise biologics in juvenile idiopathic arthritis. METHODS: A "discrete-choice" methodology was used. In a nominal group meeting, factors which may influence physicians' decisions to optimise biological dose were identified, together with decision nodes. 1000Minds® was used to create multiple fictitious clinical scenarios based on the factors identified, and to deploy surveys that were sent to a panel of experts. These experts decided for each item which of two clinical scenarios prompted them to optimise the dose of biologic. A conjoint analysis was carried out, and the partial-value functions and the weights of relative importance calculated. RESULTS: In the nominal group, three decision nodes were identified: (1) time to decide; (2) to maintain/reduce or prolong interval; (3) what drug to reduce. The factors elicited were different for each node and included patient and drug attributes. The presence of macrophage activation syndrome (MAS), systemic involvement, or subclinical inflammation made the decision easier (highest weights). The presence of joints of difficult control and year of debut influenced the decision in some but not all, and in different directions. Immunogenicity, adherence, and concomitant treatments were also aspects taken into account. CONCLUSIONS: The decision to optimise the dose of biological therapy in children and youngster can be divided into several nodes, and the factors, both patient and therapy-related, leading to the decision can be detailed. These decisions taken by experts may be transported to practice, study designs, and guidelines.

Objetivo: Analizar los factores que intervienen en la decisión de optimizar el biológico en la artritis idiopática juvenil. Métodos: Se utilizó la metodología de «elección discreta». Mediante grupo nominal se identificaron factores potencialmente influyentes en la decisión de optimizar la dosis de biológico y los nodos de decisión. Con 1000Minds® se crearon escenarios clínicos ficticios basados en los factores identificados que se mostraron en encuestas a un panel de expertos. Cada ítem de las encuestas mostraba 2 escenarios clínicos y los expertos elegían el que les llevaría a optimizar el biológico. Se realizó un análisis conjunto, calculándose las funciones de valor parcial y los pesos de importancia relativa. Resultados: Se identificaron 3 nodos de decisión: 1) dilatar decisión o no; 2) mantener/reducir o prolongar el intervalo; y 3) qué fármaco reducir. Los factores identificados varían por nodo e incluyen atributos del paciente y del fármaco. La presencia del síndrome de activación macrofágica, la afectación sistémica o la inflamación subclínica facilitaron la decisión (pesos más altos). La presencia de articulaciones de difícil control y el año de inicio influyeron en la decisión en algunos casos, pero no en todos, y en diferentes direcciones. La inmunogenicidad, la adherencia y los tratamientos concomitantes también fueron aspectos decisivos. Conclusiones: La decisión de optimizar la dosis de biológico en artritis idiopática juvenil se divide en varios nodos y se pueden detallar factores, tanto del paciente como del tratamiento, que determinan la decisión. Estas decisiones de experto pueden transportarse a la práctica, la investigación y las recomendaciones.(AU)

Predictors of mental health service utilization as adolescents with attention deficit hyperactivity disorder transition into adulthood.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) symptoms may persist into adulthood and are likely to cause great problems in young adults. To date, few studies have explored the characteristics of patients diagnosed with ADHD that might influence the utilization of adult mental health services (AMHS). We aimed to examine and identify predictive symptoms of AMHS. METHODS: We analysed data from 114 participants diagnosed with ADHD from a cohort of adolescents recruited at the age of 12-17 years, who, at the time of data analysis, were over 18 years old. RESULTS: Among AMHS users, hyperactivity/impulsivity measures were significantly more severe (t = 2.668, df = 112, p < .001), ADHD combined subtype diagnosis (χ2  = 4.66, df = 1, p = .031) was more frequent and dysregulation profile in the SDQ-P was also significantly higher (t = -2.497, df = 109, p = .014). However, the dysregulation profile did not remain statistically significant after controlling for type of AMHS contact. CONCLUSIONS: Our findings suggest that adolescents with ADHD are more likely continue their care under AMHS if they present more severe symptoms of hyperactivity/impulsivity and emotional dysregulation. The better characterization of the patient profile will help clinicians to early identify groups at-risk and to tailor interventions and prevention strategies.

Dual latent tuberculosis screening with tuberculin skin tests and QuantiFERON-TB assays before TNF-α inhibitor initiation in children in Spain.

Tumor-necrosis-factor-α inhibitors (anti-TNF-α) are associated with an increased risk of tuberculosis (TB) disease, primarily due to reactivation of latent TB infection (LTBI). We assessed the performance of parallel LTBI screening with tuberculin skin test (TST) and QuantiFERON-TB Gold In-Tube assays (QFT-GIT) before anti-TNF-α treatment in children with immune-mediated inflammatory disorders in a low TB-burden setting. We conducted a multicenter cohort study involving 17 pediatric tertiary centers in Spain. LTBI was defined as the presence of a positive TST and/or QFT-GIT result without clinical or radiological signs of TB disease. A total of 270 patients (median age:11.0 years) were included, mainly with rheumatological (55.9%) or inflammatory bowel disease (34.8%). Twelve patients (4.4%) were diagnosed with TB infection at screening (LTBI, n = 11; TB disease, n = 1). Concordance between TST and QFT-GIT results was moderate (TST+/QFT-GIT+, n = 4; TST-/QFT-GIT+, n = 3; TST+/QFT-GIT-, n = 5; kappa coefficient: 0.48, 95% CI: 0.36-0.60). Indeterminate QFT-GIT results occurred in 10 patients (3.7%) and were associated with young age and elevated C-reactive protein concentrations. Eleven of 12 patients with TB infection uneventfully completed standard LTBI or TB treatment. During a median follow-up period of 6.4 years, only 2 patients developed TB disease (incidence density: 130 (95% CI: 20-440) per 100,000 person-years), both probable de novo infections. CONCLUSION: A substantial number of patients were diagnosed with LTBI during screening. The dual strategy identified more cases than either of the tests alone, and test agreement was only moderate. Our data show that in children in a low TB prevalence setting, a dual screening strategy with TST and IGRA before anti-TNF-α treatment is effective. WHAT IS KNOWN: • The optimal screening strategy for latent tuberculosis in children with immune-mediated inflammatory disorders remains uncertain. • Children receiving anti-TNF-α drugs are at increased risk of developing severe tuberculosis disease. WHAT IS NEW: • A dual screening strategy, using TST and an IGRA assay, identified more children with latent tuberculosis than either of the tests alone. • Identification and treatment of latent tuberculosis before initiation of anti-TNF-α therapy averted incident tuberculosis cases.

Attention Deficit Hyperactivity Disorder Assessment Based on Patient Behavior Exhibited in a Car Video Game: A Pilot Study.

Symptoms of Attention Deficit Hyperactivity Disorder (ADHD) include excessive activity, difficulty sustaining attention, and inability to act in a reflective manner. Early diagnosis and treatment of ADHD is key but may be influenced by the observation and communication skills of caregivers, and the experience of the medical professional. Attempts to obtain additional measures to support the medical diagnosis, such as reaction time when performing a task, can be found in the literature. We propose an information recording system that allows to study in detail the behavior shown by children already diagnosed with ADHD during a car driving video game. We continuously record the participants' activity throughout the task and calculate the error committed. Studying the trajectory graphs, some children showed uniform patterns, others lost attention from one point onwards, and others alternated attention/inattention intervals. Results show a dependence between the age of the children and their performance. Moreover, by analyzing the positions by age over time using clustering, we show that it is possible to classify children according to their performance. Future studies will examine whether this detailed information about each child's performance pattern can be used to fine-tune treatment.

Impulsivity as a mediator between childhood maltreatment and suicidal behavior: A systematic review and meta-analysis.

Childhood maltreatment is a known risk factor for the development of suicidal behavior. Possible mediators of the association between childhood maltreatment and suicide have been analyzed. Some studies have considered impulsivity as one of these mediators, but there are no previous reviews on this topic. We, therefore, present a systematic review and mediation meta-analysis of the literature summarizing the evidence on impulsivity as a mediator of the relationship between childhood maltreatment and lifetime suicidal behavior. This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The review was registered in the PROSPERO database. We searched PubMed, PsycINFO, WebOfScience, and EMBASE databases up to February 2021 to identify studies exploring the association between childhood maltreatment and suicide through impulsivity. Fourteen articles met the selection criteria and were included in the review. Seven articles could be included in the mediation meta-analysis. Impulsivity was a significant mediator of the relationship between childhood maltreatment and suicidal behavior in ten of the fourteen included studies. This result was confirmed using mediation meta-analysis (ß = .06, 95% CI 0.03-0.10). Studies suggest that exposure to traumatic situations in childhood affects the proper neurobiological, cognitive, and affective development of individuals. This may increase impulsivity, which in turn would be related to an increased risk of suicide. The effects of childhood maltreatment and impulsivity may be both therapeutic targets of interest to reduce suicide rates.

Suicide Prevention in Your Pocket: A Systematic Review of Ecological Momentary Interventions for the Management of Suicidal Thoughts and Behaviors.

BACKGROUND: This study reviews the evidence on ecological momentary interventions (EMIs) for managing and preventing suicidal thoughts and behaviors. METHODS: This review follows the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Its protocol was registered in the PROSPERO database. We conducted a systematic literature search of five databases: PubMed, EMBASE, Web of Science, PsycInfo, and Cochrane library. The most recent search date was 10 September 2021. RESULTS: After screening and full-text review, 27 studies were included, totaling 19 different interventions. Many of the available interventions have not yet been clinically tested. Those that have undergone effectiveness evaluation (10 interventions) showed good rates of effectiveness and feasibility, with some exceptions. The most widely used intervention model is the safety plan, which allows the user to implement coping and distracting strategies in case of suicidal ideation. CONCLUSIONS: Ecological momentary interventions provide certain advantages, such as their wide availability, versatility, and potential for customization. These interventions can be useful complements to traditional care, especially in situations in which face-to-face care is not possible. Evidence on the effectiveness of such interventions is still scarce. Furthermore, barriers limiting implementation in clinical practice remain. The constant advance of technology means that these interventions have great potential for improvement in the coming years.

Video Games as a Complementary Therapy for Schizophrenia: A Systematic Review.

BACKGROUND: Schizophrenia is a prevalent and serious disorder. Video games have shown potential as an aid in health care for people who suffer from schizophrenia. Although video games may contribute benefit in the treatment of schizophrenia, reviews on this topic are scarce. In this article, we systematically review the evidence concerning video game-based therapeutic interventions for people diagnosed with schizophrenia. METHODS: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The review protocol was registered in the PROSPERO database. We searched 4 databases-PubMed, Web of Science, EMBASE, and clinicaltrials.gov-to identify original studies exploring video game-based therapeutic interventions for people with schizophrenia. RESULTS: After initial screening, full-text review, and study selection, 11 articles were included in the review. Most studies used video consoles as the platform, with a minority using a personal computer. Video game-based therapeutic interventions were well accepted and generally effective in improving cognitive areas. CONCLUSIONS: Cognitive training could be one of the main mechanisms underlying the usefulness and effectiveness of video game-based therapeutic interventions. Software optimization and greater collaboration between developers and health care professionals are some of the priorities for future research in this area.

Video games for the assessment and treatment of attention-deficit/hyperactivity disorder: a systematic review.

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent and serious disorder among children. Video games have shown potential for aiding in child healthcare. Video games could contribute to the assessment and management of ADHD, but there are no previous reviews on this topic. Here, we systematically review the evidence about video game-based assessment tools and interventions for children diagnosed with ADHD. This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The review protocol was registered in PROSPERO database. We searched four databases-PubMed, PsycInfo, Embase and clinicaltrials.gov-to identify original studies exploring either video game-based interventions or video game-based assessment tools in children with ADHD. After initial screening, full text revision and study selection, 22 articles were finally included in the review. Most studies used PC as platform, with a minority using a video console, pad, or 3D device. Video game-based assessment tools were generally effective in discriminating ADHD cases from controls, and in discriminating between ADHD subtypes. Video game-based therapeutic interventions were well accepted and generally effective in improving cognitive areas and decreasing ADHD symptoms. Gamification and cognitive training could be the main mechanisms underlying the usefulness and effectiveness of video game-based assessment tools and interventions. Software optimization and greater collaboration between developers and healthcare professionals are some of the priorities for future research in this area.

Long-term efficacy and safety of canakinumab in patients with mevalonate kinase deficiency: results from the randomised Phase 3 CLUSTER trial.

OBJECTIVES: To evaluate the long-term efficacy and safety of canakinumab in patients with mevalonate kinase deficiency during the open label extension (weeks 41-113) of the randomized controlled CLUSTER trial. METHODS: During a 72-week period, patients received open-label canakinumab 150 or 300 mg, every 4 or 8 weeks. The disease activity was evaluated every 8 weeks using physician global assessment and counting the number of flares. Concentrations of CRP and serum amyloid A protein were measured. The safety was studied by determination and classification of observed adverse events. The safety and efficacy were analysed separately in three subgroups of patients receiving a cumulative dose of less than <35 mg/kg, ≥35 to <70 mg/kg or ≥70 mg/kg. RESULTS: Of the 74 patients who started the CLUSTER study, 66 entered Epoch 4 and 65 completed it. During the 72-week period, 42 (64%) patients experienced no flares, while 13 (20%) had one flare, as compared with a median of 12 flares per year reported at baseline. Low physician global assessment scores were seen at the end of the study for all groups with >90% reporting minimal disease activity or none at all. Median CRP concentrations were consistently equal or lower than 10 mg/l, while median serum amyloid A concentrations remained only slightly above the normal range of 10 mg/l. The study showed no new or unexpected adverse events. CONCLUSION: Canakinumab proved effective to control disease activity and prevent flares in mevalonate kinase deficiency during the 72-week study period. No new safety concerns were reported. TRIAL REGISTRATION: NCT02059291. https://clinicaltrials.gov.

Video Games for the Treatment of Autism Spectrum Disorder: A Systematic Review.

Video games are a promising area of intervention for children diagnosed with Autism Spectrum Disorders (ASD). However, reviews on this topic are scarce. This review on studies exploring video games for the treatment of ASD followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and its protocol was registered in PROSPERO. PubMed, PsycInfo, Embase, WebOfScience and clinicaltrials.gov databases were searched. Twenty-four articles were included in the review. Video game-based interventions were effective for alleviating ASD symptoms, albeit with small effect sizes. High rates of acceptability and adherence to treatment were obtained. Conclusion: Video games are a promising area for improving the treatment of children with ASD. Exploring commercial video games is one of the lines for future research.

Physical comorbidity and use of healthcare services in people with schizophrenia: protocol for a systematic review.

INTRODUCTION: People with schizophrenia die about 15-20 years earlier than the general population. A constellation of factors contributes to this gap in life expectancy: side effects of psychotropic drugs, unhealthy lifestyles (inactivity, unhealthy diet) and inequality in the provision of healthcare services. This is a topic of main importance, which requires constant update and synthesis of the literature. The aim of this review is to explore the evidence of physical comorbidity and use of healthcare services in people with schizophrenia. METHODS AND ANALYSIS: We will conduct a systematic literature search in the databases PubMed/MEDLINE, EMBASE, Scopus, Web of Science, PsycINFO and Cochrane Library, Proquest Health Research Premium Collection, in order to identify studies that answer to our research question: Are patients with schizophrenia different from the non-psychiatric population in terms of physical comorbidity and use of healthcare services? Two authors will independently review the studies and extract the data. ETHICS AND DISSEMINATION: This study does not include human or animal subjects. Thus, ethics considerations are not applicable. Dissemination plans include publications in peer-reviewed journals and discussion of results in psychiatric congresses. PROSPERO REGISTRATION NUMBER: CRD42020139972.

Accurate Prediction of Children's ADHD Severity Using Family Burden Information: A Neural Lasso Approach.

The deep lasso algorithm (dlasso) is introduced as a neural version of the statistical linear lasso algorithm that holds benefits from both methodologies: feature selection and automatic optimization of the parameters (including the regularization parameter). This last property makes dlasso particularly attractive for feature selection on small samples. In the two first conducted experiments, it was observed that dlasso is capable of obtaining better performance than its non-neuronal version (traditional lasso), in terms of predictive error and correct variable selection. Once that dlasso performance has been assessed, it is used to determine whether it is possible to predict the severity of symptoms in children with ADHD from four scales that measure family burden, family functioning, parental satisfaction, and parental mental health. Results show that dlasso is able to predict parents' assessment of the severity of their children's inattention from only seven items from the previous scales. These items are related to parents' satisfaction and degree of parental burden.

The Association Between Reading the Mind in the Eyes Test Performance and Intelligence Quotient in Children and Adolescents With Asperger Syndrome.

Background: There has been an extensive debate about a potential association between intelligence and social cognition. In this study, we aimed to assess the association between social cognition as measured with the Reading the Mind in the Eyes test (RMET) and intelligence as measured with the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV) in children and adolescents diagnosed with Asperger Syndrome (AS). Methods: We conducted a cross-sectional study among 84 children diagnosed with AS aged 6-16 years (mean = 11.64; standard deviation = 2.75; 92.9% males). We analyzed the association between RMET performance and WISC-IV total score as well as the association between RMET performance and each of the four WISC-IV indexes (processing speed index, PSI; working memory index, WMI; perceptual reasoning index, PRI, and verbal comprehension index, VCI). Results: We found a positive correlation between RMET performance and full-scale intelligence quotient (r = 0.340; p < 0.01), VCI (r = 0.310; p < 0.01), PRI (r = 0.401; p < 0.01), and WMI (r = 0.292; p < 0.01). In the linear regression model, age was a significant predictor of RMET score (ß = 0.409; p < 0.001) as was PRI (ß = 0.309; p = 0.019). Conclusion: Our results suggest that intelligence quotient positively influences RMET performance, indicating that intelligence increases social cognition in individuals diagnosed with AS. However, weak-to-moderate size effects were found. This study contributes to understanding the mechanisms underlying the disturbance of social cognition in children and adolescents diagnosed with AS.
