Validation of the Persian Version of the Palin Parent Rating Scales.

INTRODUCTION: The Palin Parent Rating Scale (Palin PRS) is a structured questionnaire filled out by parents of children who stutter. It is designed to assess the effects of stuttering on both the children and their parents. The goal of this study was to translate the Palin PRS into Persian and to evaluate its validity and reliability for application in preschool children who stutter. METHODS: This research was conducted from August 2021 to December 2022, involving 139 parents of children who stutter. The parents completed the Palin PRS and provided their demographic data. Descriptive statistics were used to examine the floor and ceiling effects on all subscales of the Palin PRS. The internal consistency of the scale was assessed using Cronbach's alpha method, while the intraclass correlation coefficient (ICC) was calculated to determine its test-retest reliability. An exploratory factor analysis was also performed to clarify the factor structure of the scale. RESULTS: The exploratory factor analysis results were highly consistent with the factor structure found in the original version. No floor or ceiling effects were observed for the factors of the Palin PRS. The three factors of the Persian version of the Palin PRS (P-Palin PRS) showed good internal consistency (Cronbach's alpha >0.8) and excellent test-retest reliability (ICC >0.9). Additionally, normative scores were derived by converting raw scores into Stanine scores. CONCLUSION: The P-Palin PRS showed strong reliability, thereby establishing it as a suitable instrument for evaluating how parents perceive the effects of stuttering on their children and themselves. Further research may explore its application in diverse clinical settings and populations.

[Discrimination of anxiety disorders by parent ratings: A study based on the Questionnaire for Anxiety and Obsessive-Compulsive Disorders (FBB-ANZ)]. / Differenzierung von Angststörungen im Elternurteil: Untersuchung anhand des Fragebogens für Angst- und Zwangsstörungen (FBB-ANZ).

Discrimination of anxiety disorders by parent ratings: A study based on the Questionnaire for Anxiety and Obsessive-Compulsive Disorders (FBB-ANZ) Abstract. Parent ratings are often used for screening during the diagnostic evaluation of anxiety disorders. Clinically, it is important to correctly differentiate between anxiety and other psychiatric disorders and to distinguish specific anxiety disorders. The present study examined the validity of the screening results obtained by the Parent Questionnaire for Anxiety and Obsessive-Compulsive Disorders (FBB-ANZ). We examined whether the FBB-ANZ discriminated (1) anxiety and other psychiatric disorders and (2) specific anxiety disorders in children and adolescents using ROC analyses. 972 parents of 4;00-11;11-year-old children and 12;00-17;11-year-old adolescents with anxiety disorders, depressive episodes, or externalizing disorders completed the FBB-ANZ. Discrimination of anxiety disorders and externalizing disorders in children (AUC = .72) and adolescents (AUC = .76) as well as depressive episodes in children (AUC = .77) was moderate. Good discrimination of different anxiety disorders was found only for separation anxiety in children (AUC = .84) and adolescents (AUC = .87). The results indicate the limited diagnostic benefit of parent ratings for discriminating different anxiety disorders in children and adolescents. Potential explanations for the results are critically discussed.

Effect of vitamin D supplementation as adjunctive therapy to methylphenidate on ADHD symptoms: A randomized, double blind, placebo-controlled trial.

OBJECTIVES: Previous studies have shown that serum levels of vitamin D were lower in attention deficit hyperactivity disorder (ADHD) children compared to healthy controls. The aim of the study was to determine the effect of vitamin D supplementation as adjunctive therapy to methylphenidate on symptoms of children with ADHD. METHODS: Sixty-two children aged 5-12 years with a diagnosis of ADHD based on DSM-IV criteria were randomly assigned into two groups to receive either 2000IU vitamin D or placebo in addition to methylphenidate for 8 weeks. Symptoms severity was assessed by Conner's Parent Rating Scale-Revised[S] (CPRS), ADHD rating scale-IV (ADHD-RS), and Weekly Parent Ratings of Evening and Morning Behavior (WPREMB) at weeks 0, 4, and 8. Serum levels of 25(OH)D were measured at baseline and after 8 weeks. Anthropometric variables, dietary intake, physical activity, sun exposure, and side effects were assessed. RESULTS: Fifty-four participants completed the trial. After 8 weeks of supplementation, serum levels of 25(OH)D significantly increased in the vitamin D group. ADHD symptoms decreased significantly in both groups (P < 0.05). Evening symptoms and total score of WPREMB scale were significantly different at weeks 4 and 8 between the two groups (P = 0.013, 0.016, respectively), but no differences were found in symptoms by CPRS and ADHD-RS scales. DISCUSSION: Vitamin D supplementation as adjunctive therapy to methylphenidate improved ADHD evening symptoms. Future research is needed to clarify vitamin D effects as monotherapy in ADHD and its mechanism. The trial was registered in www.irct.ir is (IRCT201404222394N10).

The Validity of the Screen for Child Anxiety Related Emotional Disorders Revised (SCARED-R) Scale and Sub-Scales in Swedish Youth.

We evaluated the clinical utility of the Swedish SCARED-R in child- and adolescent psychiatric outpatients (n = 239) and validated it against Longitudinal Expert All Data (LEAD) DSM IV diagnoses based on the Children's Schedule for Affective Disorders and Schizophrenia (KSADS) and subsequent clinical work-up and treatment outcome. The SCARED-R total score and subscales had acceptable sensitivity/specificity for child and parent reports for cut-offs based on Receiver Operating Characteristics (ROC) curves, with mostly moderate area under the curve. Sensitivity ranged from 75% (parent rated social anxiety) to 79% [child rated Generalized Anxiety Disorder (GAD)]. Specificity, ranged from 60% for child-rated GAD to 88% for parent rated social anxiety. Parent-child agreement was moderate, and each informant provided unique information contributing to most diagnoses. In conclusion, the SCARED-R is useful for screening anxiety symptoms in clinical populations. However, it cannot replace interview based diagnoses, nor is it adequate to use just one informant.

Capturing Age-group Differences and Developmental Change with the BASC Parent Rating Scales.

Estimation of age-group differences and intra-individual change across distinct developmental periods is often challenged by the use of age-appropriate (but non-parallel) measures. We present a short version of the Behavior Assessment System (Reynolds & Kamphaus, 1998), Parent Rating Scales for Children (PRS-C) and Adolescents (PRS-A), which uses only their common-items to derive estimates of the initial constructs optimized for developmental studies. Measurement invariance of a three-factor model (Externalizing, Internalizing, Adaptive Skills) was tested across age-groups (161 mothers using PRS-C; 200 mothers using PRS-A) and over time (115 mothers using PRS-C at baseline and PRS-A five years later) with the original versus short PRS. Results indicated that the short PRS holds a sufficient level of invariance for a robust estimation of age-group differences and intra-individual change, as compared to the original PRS, which held only weak invariance leading to flawed developmental inferences. Importance of test-content parallelism for developmental studies is discussed.

A parent-rating scale of postpartum depression: Maternity-monitoring scale by parents (MMSP).

Postpartum depression (PPD) is an illness that is difficult for the affected women themselves to recognize. Moreover, many mothers believe that mothers should not complain about the mental difficulties of taking care of their children. Therefore, in addition to self-evaluation for PPD, evaluation from others is also necessary. We aimed to develop a novel measure to screen for PPD based on a parent-rating scale that is administered to the parents of postpartum mothers. The 15-item maternity-monitoring scale by parents (MMSP) was designed and applied to the feasibility cohort (n = 61) and the emergency cohort (n = 55). The Edinburgh Postnatal Depression Scale (EPDS) (threshold score of 8/9) was used to evaluate a high risk of PPD. An egogram-based index, the over-adaptation index for depression (OAID), was performed along with the EPDS and MMSP. In the feasibility cohort, MMSP was moderately correlated with EPDS. In the emergency cohort, under the circumstance of the state of emergency declaration over the coronavirus disease 2019 in Japan, application of the MMSP was delayed, resulting in the proportion of parents who overlooked PPD symptoms in their daughters increasing from 33 % to 50 %. Our findings suggest that a novel approach of parent-rated PDD screening of postpartum women is potentially possible, and the MMSP is a potential candidate for screening. Moreover, the OAID is also helpful in identifying women with hidden PPD, along with the EPDS. The performance of the MMSP should be confirmed in the parents of patients with PPD diagnosed by psychiatrists.

Diagnostic Utility of Parent Ratings on the Behavior Assessment System for Children-Third Edition in Children who are Deaf and Hard of Hearing and Diagnosed with Autism Spectrum Disorder.

Between 1 to 2 of every 1,000 children are born deaf or hard of hearing (DHH) and, of those, 30-50% have additional disabilities, including Autism Spectrum Disorder (ASD). Most measures assessing ASD characteristics rely on some degree of behavioral response to sound (e.g., responding to name, listening response), and may not be appropriate for use with children who are DHH. Further, ASD specific measures do not provide information on a child's functional abilities across developmental domains. We conducted a cross-sectional analysis comparing mean T-scores on a standardized multidimensional measure, the Behavior Assessment System for Children, Third Edition, Parent Rating Scale (BASC-3 PRS), across three groups matched for age and sex: children who are DHH and diagnosed with ASD (DHH + ASD; n = 16); children who are DHH without ASD (DHH-ASD; n = 16); and children who are typically hearing with ASD (H + ASD; n = 16). Analyses revealed statistically significant differences across scales of Attention Problems, Atypicality, Withdrawal, Behavioral Symptoms Index, Social Skills, Leadership, Functional Communication, Activities of Daily Living, Adaptive Skills, Autism Probability Indices, and Developmental Social Disorders. Pairwise comparisons showed DHH + ASD and H + ASD mean T-scores were statistically similar and distinct from DHH-ASD mean T-scores on all these scales except for Withdrawal, Leadership, Functional Communication, and Activities of Daily Living, where pairwise comparisons varied. The findings add to the literature on ASD and DHH children and call for further exploration of the BASC-3 as a tool for both evaluation of ASD and the development of individualized treatment plans in this unique population.

Parent ratings on the MEMRY questionnaire predict children's academic performance.

Given the high rates of learning challenges in children with medical conditions, efficient and reliable screening methods are crucial. This study examined whether parent report of daily learning and memory predicts academic achievement in youth. Parents of 213 youth (aged 6-18) with varied medical diagnoses completed the Multidimensional Everyday Memory Ratings for Youth (MEMRY), and youth completed subtests from the Wechsler Individual Achievement Test-Third Edition (WIAT-III) as part of a comprehensive assessment. All scales of the MEMRY (Learning, Daily Memory, Executive/Working Memory) correlated significantly with WIAT-III Spelling, Word Reading, and Numerical Operations, while only the MEMRY Learning subscale correlated significantly with WIAT-III Pseudoword Decoding. Regression analyses indicated that MEMRY Learning significantly predicted WIAT-III Word Reading and Spelling, while both the MEMRY Learning and MEMRY Daily Memory scales significantly predicted WIAT-III Numerical Operations. When Full Scale IQ was entered into the models first, the MEMRY Learning subscale accounted for an additional 4% of variance in WIAT-III Word Reading and 7% of variance in WIAT-III Spelling, but did not account for additional variance in WIAT-III Numerical Operations or Pseudoword Decoding. Analyses in a subset of children with broadly normal intellectual functioning demonstrated very similar results, with even higher variance in academic testing accounted for by the MEMRY. In sum, the MEMRY questionnaire may serve as an efficient screen to identify children at risk for reading, spelling, and math deficits.

Psychometric Properties of the Czech Version of the Vanderbilt ADHD Diagnostic Parent Rating Scale.

This study examined the psychometric properties of the Czech translation of the Vanderbilt ADHD Diagnostic Parent Rating Scale (VADPRS), a tool used to assess ADHD symptoms. Data was collected online from parents of school-aged children and included questions related to their child's diagnosis or treatment. The results showed that while relying on professional judgment improved specificity and positive predictive value, it decreased negative predictive value. These findings indicate that the VADPRS scale is more accurate in identifying individuals with ADHD when professionals provide the diagnosis, but fewer true negatives are found. This is the first study attempting to describe the psychometric properties of this tool in the Czech Republic and assess its use as an additional tool for ADHD diagnosis. It is recommended that structured clinical interviews be used to increase the accuracy of ADHD diagnosis.

Assessment of oppositional defiant disorder and oppositional behavior in children and adolescents with Down syndrome.

Introduction: Children and adolescents with intellectual disability (ID) exhibit higher rates of oppositional defiant disorder (ODD) than typically developing (TD) peers. However, studies focusing on the investigation of ODD prevalence in youth with Down syndrome (DS) are still limited. Methods: The current study aimed to investigate the prevalence of ODD clinical and subclinical symptoms in a group of 101 youth with DS (63 boys, 38 girls) ranging in age from 6 to 18 years. Moreover, the prevalence of ODD symptoms, as detected by means of three parent-report questionnaires, was compared with that detected by a semi-structured psychopathological interview, namely, the Schedule for Affective Disorders and Schizophrenia for School Aged Children Present and Lifetime (K-SADS) Version Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5). Results: We found that 17% of participants met diagnostic criteria for ODD on the K-SADS, whereas 24% exhibited subclinical symptoms. Results also suggest good specificity of Swanson, Nolan, and Pelham-IV Rating Scale (SNAP-IV), Conners' Parent Rating Scales Long Version (CPRS) and Child Behavior Checklist (CBCL) in detecting ODD symptoms. The investigation of the agreement in the prevalence rates of clinical and subclinical symptoms of ODD between K-SADS and the parent-report questionnaires indicated CPRS as the parent-report questionnaire with the best agreement with K-SADS. Discussion: This study provides support for the use of parent-report questionnaires to assess ODD symptoms in children and adolescents with DS by evaluating their levels of agreement with a semi-structured psychopathological interview. In particular, our results suggest that CPRS could be considered a suitable screening tool for ODD clinical and subclinical symptoms in youth with DS.

Measuring Parent Rated Interest and Deprivation Type Curiosity in Swedish Young Children - Are they Meaningfully Distinct?

Background: Proxy ratings of young children's curiosity has the potential to be useful for research in Sweden. One such proxy rating is the parent-rating Interest/Deprivation Young Children scale. This scale has previously only been validated in Dutch samples, where it differentiated curiosity dimensions of interest (joyful exploration) and deprivation (reduction of aversive feelings of not knowing). Objective: The objective of this study was to investigate internal and construct validity of the Swedish version of the Interest/Deprivation Young Children scale. Method: A translation of the Interest/Deprivation Young Children scale was conducted and then administered to 266 parents in Sweden, who rated their children (4-6-years old) on 10 items, with 5 items each for subscales of interest and deprivation dimensions of epistemic curiosity. Responses were analyzed using confirmatory factor analysis. Results: Results indicate acceptable internal reliability for deprivation-curiosity items (α = 0.78) and for interest-curiosity items (α = 0.79). For the combined scale score alpha was found good (α = 0.84). However, confirmatory factor analysis failed to differentiate interest and deprivation dimensions of curiosity. Conclusions: Item revisions are suggested which could be implemented for further investigations. Also, the possibility of using the I/D-YC total score as a more general measure of child curiosity is argued for. An open question is how other dimensions of curiosity might be more viable for proxy ratings of child curiosity.

Validity of Parent Ratings of Speech Intelligibility for Children with Cerebral Palsy.

Aim: To examine the relationship between subjective parent ratings of intelligibility and objectively measured intelligibility scores for children with cerebral palsy (CP) with differing levels of speech severity. Method: Fifty children (84-96 months) with CP were classified into groups based on intelligibility scores during a speech elicitation task - high intelligibility (90% or higher), mild-moderate intelligibility reduction (61-89%), and severe intelligibility reduction (60% or lower). Parent ratings of understandability (on a 7-point scale) were compared to intelligibility scores gathered from 100 naïve listeners. Results: For children with mild-moderate and severe intelligibility reduction, there was a large range of variability in parent ratings. For children with high intelligibility, ratings were consistent with intelligibility scores. There was a range of intelligibility scores within each rating, especially in the middle of the scale. Conclusions: For children with mild-moderate intelligibility deficits, parent ratings may best be used in conjunction with objective measurement of intelligibility.

Behavior Disorder and Social Function Impairment in Children with Basal Ganglia Germ Cell Tumors.

PURPOSE: Basal ganglia intracranial germ cell tumors (iGCTs) can specifically destroy the basal ganglia network, leading to several cognitive, learning, behavioral, and social impairments. This study aimed to investigate the behavior and social disorders of patients with basal ganglia iGCTs. PATIENTS AND METHODS: We recruited 30 newly diagnosed iGCTs patients (and their parents) for the current study. The Child Behavior Checklist/6-18 was used to evaluate emotional and behavioral problems. The Conner's Parent Rating Scales was used to assess symptoms of hyperactivity/impulsivity and conduct problems. The health-related quality of life (HRQoL) was assessed using the Pediatric Quality of Life Inventory 4.0 Generic Core Scale. Performance status was assessed using the Lansky play-performance scale and Karnofsky performance scale. The effects of basal ganglia lesions on these scores were examined. RESULTS: Patients with basal ganglia iGCTs (n = 10) had more behavioral problems (attention problems, aggressive behavior, learning problems, hyperactivity index), social function impairment, anxiety/depression, and poorer HRQoL compared to patients with non-basal ganglia iGCTs (n = 20). There was no significant difference in the Lansky play-performance/Karnofsky performance scale scores. CONCLUSION: This study demonstrates the effects of basal ganglia lesions on behavioral and emotional outcomes, social functions, and HRQoL of patients with iGCTs. The results may help to understand the function of basal ganglia and provide evidence for the benefit of early psychological intervention to improve the treatment for this rare disease.

Similar names, different results: Consistency of the associations between prenatal exposure to phthalates and parent-ratings of behavior problems in preschool children.

BACKGROUND: Environmental health research has reported mixed findings on the associations between prenatal exposure to phthalates and parent-ratings of child behavioral problems. OBJECTIVE: We examined the consistency of the associations between prenatal urinary phthalate concentrations and child behavior scores across two standardized instruments - the Behavior Assessment System for Children-Second Edition (BASC-2) and the Child Behavior Checklist (CBCL) - using two analytical approaches used to correct for urine dilution. METHOD: A sample of 351 mother-child pairs were selected from a prospective birth cohort of pregnant women enrolled between 2009 and 2012. Women provided spot urine samples during the second trimester of pregnancy, which were analyzed for levels of nine urinary phthalate metabolites. When their typically developing children were 3-4 years of age, mothers completed the BASC-2 and CBCL on the same day. Adjusted regression analyses examined the associations between maternal prenatal phthalate concentrations and child behavior scores on the BASC-2 and CBCL. To correct for urine dilution, primary regression analyses included urinary creatinine concentration as a separate independent variable (i.e., covariate). In the secondary regression analyses, creatinine-adjusted phthalate concentrations were used. RESULTS: Primary logistic regression analyses that included urinary creatinine as a covariate showed that higher prenatal phthalate concentrations were related to increased odds of scores falling into the borderline or clinical range on the Hyperactivity, Aggression, Anxiety, Depression, Withdrawal, Externalizing Problems, Internalizing Problems, and Behavioral Symptoms Index scales on the BASC-2 (ORs from 1.39 to 2.07), but only the Anxious/Depressed and Externalizing Problems scales on the CBCL (ORs from 1.80 to 3.28). Primary linear regression analyses showed that higher prenatal phthalate concentrations were related to higher scores on the Externalizing Problems (ß's = 0.16), Internalizing Problems (ß's from 0.16 to 0.20), and Behavioral Symptoms Index (ß's from 0.18 to 0.21) scales on the BASC-2, but not related to any CBCL scales. Sex-stratified analyses found that many associations were only significant for male children. Secondary analyses using creatinine-adjusted phthalate concentrations revealed that some of the associations from the primary analyses remained significant; however, a number of unique associations were observed. CONCLUSION: Prenatal phthalate exposure was associated with preschool behavioral development; however, findings were not consistent for the BASC-2 and CBCL, especially related to the clinical/syndrome scales and Internalizing Problems scale. Further, many findings differed based on the analytical approach used to correct for urine dilution. Future work is needed to delineate the similarities and differences between similarly named child behavior constructs assessed by different neurodevelopmental assessments. Also, research is needed to better understand why and how different analytical approaches influence the reported associations between maternal prenatal phthalate concentrations and children's behavior problems.

Cross-Cultural Validity of the Child and Adolescent Dispositions Model in a Clinical Sample of Children With Externalizing Behavior Problems.

Background: The Child and Adolescent Dispositions Scale-parent rating (CADS-P) explores three emotional dispositions that may enlarge the probability of future externalizing problem behavior. The English version has proven its psychometric quality within a population-based sample of children and adolescents. The presents study investigates the German version of the CADS-P by examining a clinically referred sample of children with externalizing behavior problems. Methods:The sample included 132 children aged 4-11 years with a diagnosis of attention- deficit/hyperactivity disorder (ADHD) or oppositional defiant disorder (ODD). The factor structure of the CADS-P was evaluated using exploratory (EFA) and confirmatory factor analyses (CFA). Reliability was estimated using internal consistency (Cronbach's alpha). Validity was assessed through linear regression analyses, with symptoms of externalizing [conduct disorder (CD), ODD, ADHD] and internalizing behavior problems (anxiety, depression) as criterion variables and the three CADS-P factor scores as predictors. Results:After eliminating eight items due to insufficient psychometric properties, EFA and CFA supported a three-factor solution for the German CADS-P. Cronbach's alpha coefficient exceeded α = 0.70 for all subscales. Mostly, as predicted, the CADS-P dimensions were associated with symptoms of ODD/CD and ADHD and symptoms of anxiety and depression. Conclusions:The present study provides evidence for the cross-cultural validity of the CADS- P in a non-English-Speaking country. Results show that the German version of the CADS-P is a reliable and valid parent questionnaire for assessing prosociality, negative emotionality and daring as emotional dispositions that may enlarge the probability to develop externalizing problem behavior. Trial Registration: The study was approved by the review board of the Medical Faculty of the University of Cologne (ID 09-123) and was pre-registered at ClinicalTrials.gov (ID: NCT01350986).

A Predictive Model Offor Attention Deficit Hyperactivity Disorder Based on Clinical Assessment Tools.

BACKGROUND: At present, clinicians diagnose that the clinical diagnosis of attention deficit hyperactivity disorder (ADHD) in children is mainly on the basis of the information provided by their parents, the behaviour of children in clinical clinics and the assessments of clinical rating scales and neuropsychological tests. Notably, no unified standard exists currently for analysing the results of various measurement tools for diagnosing ADHD. Therefore, clinicians interpret the results of clinical rating scales and neuropsychological tests entirely based on their clinical experience. METHODS AND SUBJECTS: To provide guidance for clinicians on how to analyse the results of various clinical assessment tools when diagnosing ADHD, this study assessed children with ADHD and children in the control group using two clinical assessment scales-parent rating scale (PSQ) and Child Behavior Checklist (CBCL)-and one neuropsychological test (Integrated Visual and Auditory Continuous Performance Testing). The two-sample t-test (FDR correction) screened the parameters of the three assessment tools with significant inter-group differences. LibSVM was used to establish a classification prediction model for analysing the accuracy of ADHD prediction using parameters of the three assessment tools and weight values of each parameter for classification prediction. RESULTS: A total of 19 parameters (16 from clinical rating scales, 3 from neuropsychological tests) with significant inter-group differences were screened. The accuracy of classification modelling was higher for the clinical rating scales (61.635%) than for the neuropsychological test (59.784%), whereas the accuracy of classification modelling was higher for the clinical rating scales combined with the neuropsychological test (70.440%) than for the former two parameters alone. The three parameters with the highest weight values were learning problem (0.731), hyperactivity/impulsivity (0.676) and activity capacity (0.569). The three parameters with the lowest weight values are integrated control force (0.028), visual attention (0.028) and integrated attention (0.034). CONCLUSION: Our study findings indicate that the diagnosis of ADHD should be based on multidimensional assessment. For a more accurate diagnosis of ADHD, assessments and that more assessment parameters should be developed on the basis of different dimensions of physiology or psychology in the future to obtain a more accurate diagnosis of ADHD. Furthermore, the predictive model for ADHD may improve our understanding and help in optimisation of the treatment of such a condition.

Parents' perceptions of children's executive functions across different cities.

Culture is thought to strongly influence the development of executive functions (EF), such that ethnic groups with similar cultural origins are generally assumed to exhibit comparable levels of EF performance. However, other characteristics, such as urbanization and Westernization, may also affect EF performance in societies comprising different ethnic groups, even if the ethnic groups share a similar cultural origin. The present study aimed to compare the perceptions of parents in three cities [China-Shenzhen (ZH group), China-Hong Kong (HK group), and Singapore (SG group)] regarding the EF performances of their children, all of whom share the same genetic and cultural (i.e., Chinese) origin. The study recruited 95 children aged 5-6 years (ZH group = 32; HK group = 32; SG group = 31). Their parents were invited to complete the Behavior Rating Inventory of Executive Function (BRIEF). The ZH group had significantly lower BRIEF scores compared to both the HK and SG groups. However, the BRIEF scores of the HK and SG groups only differed significantly in terms of the Organization of Materials domain. The results suggest city-related differences in parents' perceptions of their children's EF performances, despite their similar genetic and cultural backgrounds. We additionally discuss further interpretations of our results and the limitations of this study.

Increased prevalence of parent ratings of ADHD symptoms among children with bilateral congenital cataracts.

AIM: To investigate the behavioral and psychological disorders and the prevalence of parent ratings of attention deficit hyperactivity disorder (ADHD) symptoms among children with bilateral congenital cataracts (CCs). METHODS: This cross-sectional study investigated children with bilateral CC aged 3-8y (CC group) using Conners' Parent Rating Scale-48 (CPRS-48) from July to December 2016. The abnormal rates of psychological symptoms in CC children and normal vision (NV) children were compared using the Chi-square test. The scores of CC children were compared with those of NV children and the Chinese urban norm using the independent samples t-test and one-sample t-test, respectively. RESULTS: A total of 262 valid questionnaires were collected. The ratio of CC children to NV children was 119:143. The overall rate of psychological symptoms in CC children was 2.28 times higher than that in NV children (46.22% vs 20.28%, Pearson's χ 2=20.062; P<0.001). CC children showed higher scores for conduct problems, learning problems, impulsiveness/hyperactivity, anxiety, and hyperactivity index than NV children and the Chinese urban norm, particularly between the ages of 3 and 5y. Furthermore, male children aged between 6 and 8y showed a higher impulsive/hyperactive score than females of the same age (t=6.083, P<0.001). CONCLUSION: Children with bilateral CCs have a higher rate of ADHD symptoms than children with NV. This study provides clinical evidence that screening for psychological symptoms and particularly for ADHD symptoms in children with bilateral CC are recommended for an early diagnosis and timely treatment.

Effect of vitamin D treatment in children with attention-deficit hyperactivity disorder.

BACKGROUND: In this research the symptom improvement of attention-deficit hyperactivity disorder (ADHD) of children was assessed by oral vitamin D administration in Tabriz, Iran. METHODS: In this double-blind, randomized clinical trials, 96 children (2-18 years) were enrolled to placebo and vitamin D groups. Children took vitamin D pearl (50,000 IU/week) or placebo for 6 weeks. Children, who had the change in methylphenidate dosage and received any anticonvulsants and corticosteroids were excluded from the research. ADHD symptoms were diagnosed by Conners parent rating scale (CPRS) test at baseline and after intervention. ADHD Conners divided into inattention (IA), hyperactivity/impulsivity (H/I) and combination type (C) subscales. Vitamin D serum level was assessed at baseline and after 8 weeks in both groups. RESULTS: The differences between CPRS and its subscales were not significant at baseline (P > 0.05). The Conners IA score was decreased in vitamin D group (P < 0.05; adjusted with age and baseline values). ADHD Conners and all subscale scores reduced remarkably after intervention in patients with insufficient level of vitamin D compared to placebo (P < 0.05). CONCLUSIONS: Oral vitamin D improved ADHD symptoms with a particular effect on inattention symptoms. In addition, symptoms related to all subscales were improved remarkably in patients with insufficient level of vitamin D. Vitamin D treatment in children with ADHD could be considered due to the expand benefit of vitamin D in body.

Assessment of prevalence of attention deficit hyperactivity disorder among schoolchildren in selected schools.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is considered the most common neurodevelopmental disorder of childhood and can continue through adolescence and adulthood. Global impairment in children with ADHD increases with increasing number of concurrent disorders. The presence of ADHD in childhood increases the likelihood of additional difficulties in academic performance, social interactions, and low self-esteem developing into adolescents and young adults. AIMS: The study aims to (i) to determine the prevalence of ADHD among schoolchildren at selected schools in Kancheepuram district, (ii) to find the agreement between parent and teacher reports, and (iii) to associate the prevalence of ADHD among schoolchildren with their selected demographic variables. SETTINGS AND DESIGN: A quantitative research approach with cross-sectional research design was adopted for the study. The study focused on primary schoolchildren from the selected schools in Kancheepuram district. MATERIALS AND METHODS: Totally 3253 children aged between 8 and 11 years were enumerated from the selected six schools in Kancheepuram district after obtaining informed consent from their caregivers. The presence of ADHD was assessed using Conners' Teacher-Parent Rating Scale given to caregivers and teachers and confirmed with the Diagnostic and Statistical Manual of Mental Disorders-5 criteria for ADHD. RESULTS: The analysis revealed the overall prevalence of ADHD to be 8.8%. The subtypes of ADHD were categorized as 124 (43.3%) for inattentive type, 124 (43.3%) for hyperactive type, and 38 (13.2%) for combined type of ADHD. CONCLUSION: The present study shows a high prevalence of ADHD among primary schoolchildren.
