First evidence on a general disease ("d") factor underlying psychopathology and physical illness in adolescents.

The coexistence of mental and physical health illnesses could be accounted for by an underlying general disease factor (termed d-factor), reflecting theoretical underpinnings based on possible genetic and pathophysiological overlapping mechanisms. This study evaluated whether the d-factor underlies mental and physical health illnesses in adolescents. A series of confirmatory factor analyses were conducted using data from 1120 adolescents. The proposed common underlying factor, we believe is the d-factor, was consistently present across different modeling approaches, including unidimensional, correlated-factor, and bifactor models. The best model fit was achieved with the bifactor model represented by mental, neurological, and psychical conditions tested. The first compelling evidence was provided supporting the existence of the transdiagnostic d-factor in youth, opening the door to innovative research of comorbid mental and physical health conditions.

Psychopharmacology in children and adolescents: unmet needs and opportunities.

Psychopharmacological treatment is an important component of the multimodal intervention approach to treating mental health conditions in children and adolescents. Currently, there are many unmet needs but also opportunities, alongside possible risks to consider, regarding the pharmacological treatment of mental health conditions in children and adolescents. In this Position Paper, we highlight and address these unmet needs and opportunities, including the perspectives of clinicians and researchers from the European College of Neuropsychopharmacology-Child and Adolescent Network, alongside those of experts by lived experience from national and international associations, via a survey involving 644 participants from 13 countries, and of regulators, through representation from the European Medicines Agency. We present and discuss the evidence base for medications currently used for mental disorders in children and adolescents, medications in the pipeline, opportunities in the development of novel medications, crucial priorities for the conduct of future clinical studies, challenges and opportunities in terms of the regulatory and legislative framework, and innovations in the way research is conducted, reported, and promoted.

Onset of Inattention and Hyperactivity in Children and Adolescents With Epilepsy 6 months After the Diagnosis.

OBJECTIVE: Complete or major symptoms of ADHD are often present in epilepsy. This study evaluated inattention and hyperactivity symptoms over the first 6 months in newly diagnosed pediatric epilepsy without comorbid ADHD. METHOD: Children and adolescents with newly diagnosed epilepsy were followed for 6 months after starting antiseizure medications. The Nisonger Child Behavior Rating Form (NCBRF), Adverse Event Profile (AEP), and the Revised Wechsler Intelligence Scale for Children were used. RESULTS: There was a marked increase in attention difficulties while a moderate increase in hyperactivity levels. AEP scores, changes in non-verbal aspects of intelligence, levels of hyperactivity at the follow-up, and attention at baseline were significant predictors for inattention. In contrast, only levels of hyperactivity at the baseline and inattention at the follow-up were significant predictors for hyperactivity. CONCLUSION: Significant inattention and hyperactivity levels originated 6 months after the diagnosis of epilepsy and starting antiseizure medication.

The Structure and Diagnostic Accuracy of the QbTest in Pediatric ADHD: A Retrospective Clinical Study.

OBJECTIVE: The QbTest that combines a continuous performance task (CPT) with a motion-tracking system may help identify attention deficit hyperactivity disorder (ADHD). This study examined the structure and diagnostic ability of the QbTest in children and adolescents. METHOD: Retrospective data from 1,274 children and adolescents were analyzed. The study assessed data on a principal component analysis (PCA), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS: The QbActivity component included the variables micro-events, distance, area, and time active; the QbImpulsivity included normalized commissions and commissions (anticipatory errors were added in a version for 6-12-year-olds only); and the QbInattention included omissions, reaction time, and reaction time variation. Sensitivity ranged between 22% and 50%, specificity 79% and 96%, PPVs 40% and 95%, and NPVs 24% and 66%. CONCLUSION: The structure of the QbTest with three cardinal parameters and nine/ten CPT and motion analysis variables was supported. The diagnostic accuracy was found to be poor to moderate. Given that this is a retrospective study, the interpretation of diagnostic accuracy should be considered within this context.

Known-groups and convergent validity of the theory of mind task battery in children with autism spectrum disorder.

OBJECTIVES: One of the most promising Theory of Mind (ToM) tests developed for children with ASD is the Theory of Mind Task Battery (ToM-TB). Still, additional psychometric properties of this tool need to be assessed. The main objective of this preregistered study was to investigate the known-groups and convergent validities of the ToM-TB compared to a well-established test used to assess ToM in children with ASD (the Strange Stories Test; SST). METHODS: A total of 68 school-aged children were recruited (34 children with ASD and 34 children with typical development). The groups were matched on sex and age, and on both receptive language abilities and overall cognitive functioning. RESULTS: Regarding the known-groups validity, we found group differences in the performance on the ToM-TB and SST. Additional analyses revealed that this result tended to be more robust for the ToM-TB than for the SST. Regarding convergent validity, we showed that the ToM-TB and SST correlated strongly, for children with ASD and children with typical development. In contrast, we found small correlations of these two tests with social competence in daily life. No evidence was found for greater known-groups or convergent validity of one test compared to the other. CONCLUSION: Our data confirmed the relevance of the ToM-TB and the SST for the assessment of ToM in school-aged children. Future studies should continue to assess the psychometric qualities of various ToM tests to provide reliable information to best guide researchers and clinicians when choosing optimal neuropsychological tools.

The future of child and adolescent clinical psychopharmacology: A systematic review of phase 2, 3, or 4 randomized controlled trials of pharmacologic agents without regulatory approval or for unapproved indications.

We aimed to identify promising novel medications for child and adolescent mental health problems. We systematically searched https://clinicaltrials.gov/ and https://www.clinicaltrialsregister.eu/ (from 01/01/2010-08/23/2022) for phase 2 or 3 randomized controlled trials (RCTs) of medications without regulatory approval in the US, Europe or Asia, including also RCTs of dietary interventions/probiotics. Additionally, we searched phase 4 RCTs of agents targeting unlicensed indications for children/adolescents with mental health disorders. We retrieved 234 ongoing or completed RCTs, including 26 (11%) with positive findings on ≥ 1 primary outcome, 43 (18%) with negative/unavailable results on every primary outcome, and 165 (70%) without publicly available statistical results. The only two compounds with evidence of significant effects that were replicated in ≥ 1 additional RCT without any negative RCTs were dasotraline for attention-deficit/hyperactivity disorder, and carbetocin for hyperphagia in Prader-Willi syndrome. Among other strategies, targeting specific symptom dimensions in samples stratified based on clinical characteristics or established biomarkers may increase chances of success in future development programmes.

Self-Harm in Children and Adolescents Who Presented at Emergency Units During the COVID-19 Pandemic: An International Retrospective Cohort Study.

OBJECTIVE: To compare psychiatric emergencies and self-harm at emergency departments (EDs) 1 year into the pandemic, to early pandemic and pre-pandemic, and to examine the changes in the characteristics of self-harm presentations. METHOD: This retrospective cohort study expanded on the Pandemic-Related Emergency Psychiatric Presentations (PREP-kids) study. Routine record data in March to April of 2019, 2020, and 2021 from 62 EDs in 25 countries were included. ED presentations made by children and adolescents for any mental health reasons were analyzed. RESULTS: Altogether, 8,174 psychiatric presentations were recorded (63.5% female; mean [SD] age, 14.3 [2.6] years), 3,742 of which were self-harm presentations. Rate of psychiatric ED presentations in March to April 2021 was twice as high as in March to April 2020 (incidence rate ratio [IRR], 1.93; 95% CI, 1.60-2.33), and 50% higher than in March to April 2019 (IRR, 1.51; 95% CI, 1.25-1.81). Rate of self-harm presentations doubled between March to April 2020 and March to April 2021 (IRR, 1.98; 95% CI, 1.68-2.34), and was overall 1.7 times higher than in March to April 2019 (IRR, 1.70; 95% CI, 1.44-2.00). Comparing self-harm characteristics in March to April 2021 with March to April 2019, self-harm contributed to a higher proportion of all psychiatric presentations (odds ratio [OR], 1.30; 95% CI, 1.05-1.62), whereas female representation in self-harm presentations doubled (OR, 1.98; 95% CI, 1.45-2.72) and follow-up appointments were offered 4 times as often (OR, 4.46; 95% CI, 2.32-8.58). CONCLUSION: Increased pediatric ED visits for both self-harm and psychiatric reasons were observed, suggesting potential deterioration in child mental health. Self-harm in girls possibly increased and needs to be prioritized. Clinical services should continue using follow-up appointments to support discharge from EDs.

Orexin/Hypocretin System Dysfunction in ESSENCE (Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations).

Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations (ESSENCE) is an umbrella term covering a wide range of neurodevelopmental difficulties and disorders. Thus, ESSENCE includes attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and other neurodevelopmental disorders (NDDs) and difficulties, with a variety of symptoms in cognitive, motor, sensory, social, arousal, regulatory, emotional, and behavioral developmental domains, frequently co-occurring and likely having partly common neurobiological substrates. The ESSENCE concept is a clinical paradigm that promotes organizing NDDs in everyday clinical practice according to their coexistence, symptom dimensions overlapping, and treatment possibilities. Despite increased knowledge regarding NDDs, the neurobiological mechanisms that underlie them and other ESSENCE-related problems, are not well understood. With its wide range of neural circuits and interactions with numerous neurotransmitters, the orexin/hypocretin system (Orx-S) is possibly associated with a variety of neurocognitive, psychobiological, neuroendocrine, and physiological functions and behaviors. Dysfunction of Orx-S has been implicated in various psychiatric and neurological disorders. This article provides an overview of Orx-S dysfunctions' possible involvement in the development, presentation, and maintenance of ESSENCE. We provide a focused review of current research evidence linking orexin neuropeptides with specific clinical NDDs symptoms, mostly in ADHD and ASD, within the Research Domain Criteria (RDoC) framework. We propose that Orx-S dysfunction might have an important role in some of these neurodevelopmental symptom domains, such as arousal, wakefulness, sleep, motor and sensory processing, mood and emotional regulation, fear processing, reward, feeding, attention, executive functions, and sociability. Our perspective is presented from a clinical point of view. Further, more thorough systematic reviews are needed as well as planning of extensive new research into the Orx-S's role in ESSENCE, especially considering RDoC elements.

Quality of Life of Children Engaged in Regular Physical Activities.

Background: We aimed to examine the quality of life of children who engage in regular physical activities. Methods: We conducted a cross-sectional study with intersectional 301 children (182 boys and 119 girls) involved in regular sporting activities and the control group of 100 children (67 boys and 33 girls), not involved in extracurricular sports. Children in both groups were from 8 to 13 years, attending elementary school, and without any associated illnesses. The quality of life (QOL) was assessed using the Quality of Life questionnaire Kidscreen-27 version for parents. For comparison of groups, we used χ2 test, and for comparison of mean values among groups we used ANOVA test. Results: More boys were engaged in sport than girls and the choice of sport is gender-dependent (P<0.01). Boys preferred collective sports, while girls were more oriented towards individual sports (P<0.01). A significant statistical difference in the mean values of the socializing dimension was given to children who trained football (P=0.04) and basketball (P=0.02). In children engaged in volleyball, a statistical difference in the mean values was observed in all dimensions of the questionnaire. In children who trained water polo, a statistically significant difference in the mean values for dimensions of health (P<0.01), mood (P<0.01) and friendship (P=0.01) was seen. Conclusion: KIDSCREEN scores were significantly higher in the examined group than in the control group, with a statistically significant difference between scores for different sports. Children involved in regular extracurricular physical activities had better QOL.

Serum-derived extracellular vesicles: Novel biomarkers reflecting the disease severity of COVID-19 patients.

COVID-19 is characterized by a wide spectrum of disease severity, whose indicators and underlying mechanisms need to be identified. The role of extracellular vesicles (EVs) in COVID-19 and their biomarker potential, however, remains largely unknown. Aiming to identify specific EV signatures of patients with mild compared to severe COVID-19, we characterized the EV composition of 20 mild and 26 severe COVID-19 patients along with 16 sex and age-matched healthy donors with a panel of eight different antibodies by imaging flow cytometry (IFCM). We correlated the obtained data with 37 clinical, prerecorded biochemical and immunological parameters. Severe patients' sera contained increased amounts of CD13+ and CD82+ EVs, which positively correlated with IL-6-producing and circulating myeloid-derived suppressor cells (MDSCs) and with the serum concentration of proinflammatory cytokines, respectively. Sera of mild COVID-19 patients contained more HLA-ABC+ EVs than sera of the healthy donors and more CD24+ EVs than severe COVID-19 patients. Their increased abundance negatively correlated with disease severity and accumulation of MDSCs, being considered as key drivers of immunopathogenesis in COVID-19. Altogether, our results support the potential of serum EVs as powerful biomarkers for COVID-19 severity and pave the way for future investigations aiming to unravel the role of EVs in COVID-19 progression.

The COVID-19 Pandemic and Adolescents' Psychological Distress: A Multinational Cross-Sectional Study.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has continued for more than two years, and the impact of this pandemic on mental health has become one of the most important research topics in psychiatry and psychology. The aim of the present study was to assess psychological distress in adolescents across five countries (Sweden, Morocco, Serbia, Vietnam, and the United States of America) during the COVID-19 pandemic. METHODS: Using nonparametric analyses we examined the impact of COVID-19 on distress, measured by the Brief Symptom Inventory, in a sample of 4670 adolescents. RESULTS: Our results showed that the association between the COVID-19 impact and psychological distress in adolescents' lives was positive and moderate in Morocco and Serbia, positive and weak in Vietnam and the United States of America, and negative and weak in Sweden. We also found that female adolescents reported higher distress levels than male adolescents. CONCLUSIONS: COVID-19 impacted adolescents and their psychological distress differently depending on their residence.

Cross-cultural measurement invariance of the Quality of Life Enjoyment and Satisfaction Questionnaire-Short form across ten countries: the application of Bayesian approximate measurement invariance.

BACKGROUND: The Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) is the most frequently used generic quality of life (QOL) measure in many countries and cultures worldwide. However, no single study has been carried out to investigate whether this questionnaire performs similarly across diverse cultures/countries. Accordingly, this study aimed to assess the cross-cultural measurement invariance of the Q-LES-Q-SF across ten different countries. METHODS: The Q-LES-Q-SF was administrated to a sample of 2822 university students from ten countries: Bangladesh, Brazil, Croatia, India, Nepal, Poland, Serbia, Turkey, the United Arab Emirates, and Vietnam. The Bayesian approximate measurement invariance approach was used to assess the measurement invariance of the Q-LES-Q-SF. RESULTS: Approximate measurement invariance did not hold across the countries for the Q-LES-Q-SF, with only two out of 14 items being non-invariant; namely items related to doing household and leisure time activities. CONCLUSIONS: Our findings did not support the cross-cultural measurement invariance of the Q-LES-Q-SF; thus, considerable caution is warranted when comparing QOL scores across different countries with this measure. Item rewording and adaptation along with calibrating non-invariant items may narrow these differences and help researchers to create an invariant questionnaire for reliable and valid QOL comparisons across different countries.

ASD with ADHD vs. ASD and ADHD alone: a study of the QbTest performance and single-dose methylphenidate responding in children and adolescents.

BACKGROUND: The continuous performance task (CPT) may help identify coexistent attention deficit hyperactivity disorder (ADHD) in autism spectrum disorder (ASD). The Quantified behavior Test (QbTest) combines a CPT and motion-tracking data to assess ADHD symptoms. This study aimed to evaluate the QbTest performance of children and adolescents with ASD plus ADHD, including estimating the effects of single-dose methylphenidate (MPH). To achieve these aims, (1) the QbTest performances were evaluated in ASD alone, ASD plus ADHD, and ADHD alone, and (2) the effects on the QbTest performance of single-dose MPH before and after intake were estimated across the groups. It was assumed that the ASD plus ADHD performance, including the MPH response, would preferably resemble the performance in ADHD alone, rather than ASD alone. METHODS: Retrospective data were analyzed for 482 children and adolescents: 69 with ASD alone, 142 with ASD plus ADHD (ASD/ADHD), and 271 with ADHD alone. For 343 subjects, the QbTest was performed before and up to four hours after a single-dose MPH intake. A summary index of the CPT and motion-capture data was provided for QbTest cardinal parameters. RESULTS: Of 12 QbTest parameters assessed before given MPH, the ASD/ADHD group had scores in line with the ASD group regarding four parameters and the ADHD group regarding nine parameters. Significant differences between groups were seen with respect to QbInattention (p > 0.05); the lowest scores in ASD and the highest in ADHD. Those with ASD/ADHD and ADHD had similar QbActivity and QbImpulsivity scores, but significantly higher than those with ASD. After MPH intake, scores for QbActivity decreased similarly in ASD/ADHD and ADHD, as well as scores for QbImpulsivity. QbImpulsivity increased in ASD. QbInattention scores decreased similarly in all groups after MPH intake. CONCLUSIONS: Children and adolescents with ASD plus ADHD exhibited more atypical QbTest performances than those with ASD alone, while most of their performances were similar to those observed in ADHD alone. In addition, a single dose of MPH mitigated attention deficits and decreased hyperactivity while improved impulsivity in these children. Prospective studies should further clarify the role of the QbTest in the diagnostic and therapeutic interventions in ASD with ADHD.

Lockdown stringency and paediatric self-harm presentations during COVID-19 pandemic: retrospective cohort study.

BACKGROUND: Lockdown during the pandemic has had significant impacts on public mental health. Previous studies suggest an increase in self-harm and suicide in children and adolescents. There has been little research on the roles of stringent lockdown. AIMS: To investigate the mediating and predictive roles of lockdown policy stringency measures in self-harm and emergency psychiatric presentations. METHOD: This was a retrospective cohort study. We analysed data of 2073 psychiatric emergency presentations of children and adolescents from 23 hospital catchment areas in ten countries, in March to April 2019 and 2020. RESULTS: Lockdown measure stringency mediated the reduction in psychiatric emergency presentations (incidence rate ratio of the natural indirect effect [IRRNIE] = 0.41, 95% CI [0.35, 0.48]) and self-harm presentations (IRRNIE = 0.49, 95% CI [0.39, 0.60]) in 2020 compared with 2019. Self-harm presentations among male and looked after children were likely to increase in parallel with lockdown stringency. Self-harm presentations precipitated by social isolation increased with stringency, whereas school pressure and rows with a friend became less likely precipitants. Children from more deprived neighbourhoods were less likely to present to emergency departments when lockdown became more stringent. CONCLUSIONS: Lockdown may produce differential effects among children and adolescents who self-harm. Development in community or remote mental health services is crucial to offset potential barriers to access to emergency psychiatric care, especially for the most deprived youths. Governments should aim to reduce unnecessary fear of help-seeking and keep lockdown as short as possible. Underlying mediation mechanisms of stringent measures and potential psychosocial inequalities warrant further research.

DIFFERENCE IN PREDICTORS OF ANASTOMOTIC LEAKAGE DEPENDING ON THE LEVEL OF ANASTOMOSIS AFTER COLORECTAL CANCER SURGERY.

Anastomotic leak (AL) after colorectal cancer surgery is one of the most serious postoperative complications which has major impact on outcomes. The aim of this study was to investigate preoperative and intraoperative risk factors for AL, as well as to examine whether there are differences in risk factors for AL depending on the primary tumor location. We retrospectively reviewed records of patients having undergone colorectal surgical procedures for malignancies between January 2013 and December 2017 in a single institution. Only procedures with primary anastomosis were included. Of the 153 patients, AL occurred in 10.6% of patients with primary tumor in the sigmoid colon and rectum, and in 8.2% of patients with primary tumor in the proximal sections of the colon. On univariate analysis, delayed oral intake and more advanced histologic stages of the tumor were significantly correlated with AL in patients with tumors in the sigmoid colon and rectum, and multiorgan resection and distant metastases in patients with tumors in the proximal sections of the colon. In conclusion, risk factors for the occurrence of AL vary depending on the primary tumor location and further investigation is needed to provide better insight into these differences.

Measurement properties of the life history of aggression in adolescents: Data from Morocco, Serbia, Sweden, Vietnam, and the USA.

The Life History of Aggression (LHA) is a frequently used scale for assessing trait aggression, but its psychometric properties have not been evaluated among adolescents. The aim of this study was to evaluate the psychometric properties of the LHA among high school students from Morocco, Serbia, Sweden, Vietnam, and the United States of America (USA). The total sample included 4867 adolescents, aged 15-19 years, from Morocco (n = 508), Serbia (n = 1067), Sweden (n = 1570), Vietnam (n = 1401), and the USA (n = 321). A two-factor, nine-item model containing an aggression factor (5 items) and a consequences/antisocial behavior factor (4 items) was created. The two-factor model had an acceptable-to-good model fit for the data for the total sample and all five countries, including gender. Cronbach's alpha (α) was satisfactory across countries. Still, the construct was noninvariant across countries and genders. The LHA with nine items in two subscales showed sound construct validity and internal consistency and can be used for group-level or within-group assessments of trait aggression in adolescents by either gender or country. However, it should not be used for cross-gender or cross-country comparisons due to a lack of measurement invariance.

Pandemic-related emergency psychiatric presentations for self-harm of children and adolescents in 10 countries (PREP-kids): a retrospective international cohort study.

To examine the differences in hospital emergency psychiatric presentations for self-harm of children and adolescents during the covid-19 lockdown in March and April 2020 compared with the same period in 2019. Retrospective cohort study. We used electronic patient records from 23 hospital emergency departments in ten countries grouped into 14 areas. We examined data on 2073 acute hospital presentations by 1795 unique children and adolescents through age 18. We examined the total number of emergency psychiatric hospital presentations and the proportion of children and adolescents presenting with severe self-harm as our two main outcome measures. In addition, we examined sociodemographic and clinical characteristics and clinical management variables for those presenting with self-harm. To compare the number of hospital presentations between 2020 and 2019 a negative binomial model was used. For other variables, individual participant data (IPD) meta-analyses were carried out. Emergency psychiatric hospital presentations decreased from 1239 in 2019 to 834 in 2020, incident rate ratio 0.67, 95% CI 0.62-0.73; p < 0.001. The proportion of children and adolescents presenting with self-harm increased from 50% in 2019 to 57% in 2020, odds ratio 1.33, 1.07-1.64; p = 0.009 but there was no difference in the proportion presenting with severe self-harm. Within the subpopulation presenting with self-harm the proportion of children and adolescents presenting with emotional disorders increased from 58 to 66%, odds ratio 1.58, 1.06-2.36; p = 0.025. The proportion of children and adolescents admitted to an observation ward also decreased from 13 to 9% in 2020, odds ratio 0.52, 0.28-0.96; p = 0.036. Service planners should consider that, during a lockdown, there are likely to be fewer emergency psychiatric presentations. Many children and adolescents with psychiatric emergencies might not receive any service. A focus on developing intensive community care services with outreach capabilities should be prioritised.

COVID-19 pandemic-related aspects and predictors of emotional and behavioural symptoms in youth with pre-existing mental health conditions: results from Georgia, Lithuania, Romania, Serbia, and Turkey.

OBJECTIVE: This study evaluated levels of and predictors of emotional and behavioral symptoms in youth with pre-existing mental health conditions over the early phase of the COVID-19 pandemic in 2020 across Georgia, Lithuania, Romania, Serbia, and Turkey. METHODS: The study included 421 children and adolescents aged 5 - 18 years with pre-existing mental health conditions and corresponding ongoing treatments. We used a parent- and/or child-report, which taps into a broad range of mental health symptoms and contextual factors thought to be particularly pertinent during periods of social restrictions. Data were collected simultaneously across the countries from May 2020 to August 2020. RESULTS: According to parents, 121 (33.1%) children had deteriorations in the overall quality of mental health over the COVID-19, 156 (43.1%) deteriorations in the quantity of mental health care received, while 82 (25.1%) mental health care received did not meet the needs. For 121 (49.8%) of children, there was worsening in the main presenting psychiatric symptom compared to January 2020, while for 64 (26.3%) there was some improvement. In total, 128 (43.9%) children reported worsened emotional and 118 (40.6%) behavioral symptoms. The COVID-related worry, parental emotional difficulties, and parent-child relationships emerged as the most relevant predictors for higher levels of emotional and behavioral difficulties. CONCLUSIONS: This study found that the COVID-19 pandemic has considerably changed the daily lives of some children with pre-existing mental health conditions, where almost every second child had deteriorations in overall mental health or worsening of psychiatric symptoms.

Cognitive profile, psychopathological symptoms, and quality of life in newly diagnosed pediatric epilepsy: A six-month, naturalistic follow-up study.

Long-term studies indicated changes in aspects of cognition, psychopathology, and quality of life (QOL) in children and adolescents followed up after the diagnosis of epilepsy. However, evidence is limited regarding what happens during the first few months after epilepsy is diagnosed because at this phase is possible to adjust and/or change an AED regimen or add other treatment interventions, if needed. This is a naturalistic, six months follow-up study that evaluated changes in overall cognitive profiles, levels of psychopathological symptoms, and quality of life (QOL) in newly diagnosed, uncomplicated pediatric epilepsy. In total, 61 (35 [57.4%] males) children and adolescents aged 7-18 years were assessed at the time of diagnosis and the initiation of antiepileptic drug (AED) treatment and six months afterward. The Revised Wechsler Intelligence Scale for Children, the Revised Child Anxiety and Depression Scale (RCADS), Nisonger Child Behavior Rating Form for typically developing children and adolescents (NCBRF), KIDSCREEN-10 Quality of Life Measure, and Adverse Event Profile (AEP) were used. The RCADS and NCBRF scores significantly increased over time, while the KIDSCREEN-10 scores significantly decreased. The most significant increases were observed in scores measuring social phobia and depressive symptoms and inattentiveness. Verbal cognitive abilities and full-scale intelligence scores changed slightly, while more changes were found in aspects of non-verbal cognitive abilities. This study showed that six months after epilepsy diagnosis and AED initiation, there were marked increases in anxiety levels, depressive symptoms, and behavioral problems, with deteriorations in QOL, while cognitive changes were relatively minimal. Therefore, monitoring levels of psychopathological symptoms and QOL in newly diagnosed epilepsy is highly recommended.

Measurement invariance of the Childhood Autism Rating Scale (CARS) across six countries.

The Childhood Autism Rating Scale (CARS) is a simple and inexpensive tool for Autism spectrum disorder (ASD) assessments, with evidenced psychometric data from different countries. However, it is still unclear whether ASD symptoms are measured the same way across different societies and world regions with this tool, since data on its cross-cultural validity are lacking. This study evaluated the cross-cultural measurement invariance of the CARS among children with ASD from six countries, for whom data were aggregated from previous studies in India (n = 101), Jamaica (n = 139), Mexico (n = 72), Spain (n = 99), Turkey (n = 150), and the United States of America (n = 186). We analyzed the approximate measurement invariance based on Bayesian structural equation modeling. The model did not fit the data and its measurement invariance did not hold, with all items found non-invariant across the countries. Items related to social communication and interaction (i.e., relating to people, imitation, emotional response, and verbal and nonverbal communication) displayed lower levels of cross-country non-invariance compared to items about stereotyped behaviors/sensory sensitivity (i.e., body and object use, adaptation to change, or taste, smell, and touch response). This study found that the CARS may not provide cross-culturally valid ASD assessments. Thus, cross-cultural comparisons with the CARS should consider first which items operate differently across samples of interest, since its cross-cultural measurement non-invariance could be a source of cross-cultural variability in ASD presentations. Additional studies are needed before drawing valid recommendations in relation to the cultural sensitivity of particular items.
