When two cognitive processes contribute to a behavioral output-each process producing a specific distribution of the behavioral variable of interest-and when the mixture proportion of these two processes varies as a function of an experimental condition, a common density point should be present in the observed distributions of the data across said conditions. In principle, one can statistically test for the presence (or absence) of a fixed point in experimental data to provide evidence in favor of (or against) the presence of a mixture of processes, whose proportions are affected by an experimental manipulation. In this paper, we provide an empirical diagnostic of this test to detect a mixture of processes. We do so using resampling of real experimental data under different scenarios, which mimic variations in the experimental design suspected to affect the sensitivity and specificity of the fixed-point test (i.e., mixture proportion, time on task, and sample size). Resampling such scenarios with real data allows us to preserve important features of data which are typically observed in real experiments while maintaining tight control over the properties of the resampled scenarios. This is of particular relevance considering such stringent assumptions underlying the fixed-point test. With this paper, we ultimately aim at validating the fixed-point property of binary mixture data and at providing some performance metrics to researchers aiming at testing the fixed-point property on their experimental data., (© 2023.

Objectives: The purpose of this study was to develop the Avoidance of Daily Activities Photo Scale (ADAP Shoulder Scale) to measure shoulder pain-related avoidance behavior in patients with shoulder pain and evaluate and report the structural validity and internal consistency of the scale., Methods: Potential daily activities involving the shoulder were selected from the activities and participation domain of the International Classification of Functioning, Disability and Health. The selected activities were presented to an expert panel, health care professionals, and patients with shoulder pain with the question "How much do you think it is important to ask patients with shoulder pain about this activity?" Activities attaining a content validity index (CVI) ≥ 0.8 were represented using a digitally colored photograph. Activity photographs were evaluated by health care professionals and patients with shoulder pain. Photographs with a CVI ≥ 0.8 were included in the scale. To evaluate structural validity and internal consistency of the scale, exploratory factor analysis was performed to determine the presence of any scale domain. Cronbach alpha was calculated to indicate the internal consistency of each domain., Results: Of the 107 preselected activities, 21 attained a CVI ≥ 0.8. Eighteen photographs (CVI ≥ 0.8) were included in the scale after being analyzed by 120 health care professionals and 50 patients with shoulder pain. Exploratory factor analysis (N = 156) showed that the ADAP Shoulder Scale consists of 3 domains: free movement, high effort, and self-care. The internal consistencies of the domains were 0.92, 0.89, and 0.92, respectively., Conclusion: The ADAP Shoulder Scale included 15 photographs distributed in 3 domains. All domains had a high internal consistency. The scale is easily applicable, well understood, and relevant for shoulder pain., Impact: The ADAP Shoulder Scale can be used to rate shoulder pain-related avoidance behaviors., (© The Author(s) 2022.

Background: Hypoxic ischemic (HI) brain injury is a significant cause of childhood neurological deficits. Preclinical rodent models are often used to study these deficits; however, no preclinical study has determined which behavioral tests are most appropriate for long-term follow up after neonatal HI., Methods: HI brain injury was induced in postnatal day (PND) 10 rat pups using the Rice-Vannucci method of unilateral carotid artery ligation. Rats underwent long-term behavioral testing to assess motor and cognitive outcomes between PND11-50. Behavioral scores were transformed into Z-scores and combined to create composite behavioral scores., Results: HI rats showed a significant deficit in three out of eight behavioral tests: negative geotaxis analysis, the cylinder test and the novel object recognition test. These individual test outcomes were transformed into Z-scores and combined to create a composite Z-score. This composite z-score showed that HI rats had a significantly increased behavioral burden over the course of the experiment., Conclusion: In this study we have identified tests that highlight specific cognitive and motor deficits in a rat model of neonatal HI. Due to the high variability in this model of neonatal HI brain injury, significant impairment is not always observed in individual behavioral tests, but by combining outcomes from these individual tests, long-term behavioral burden can be measured., (Copyright © 2021 Elsevier B.V.

Background: The Behavior Problems Inventory-Short Form (BPI-S), which assesses behavior problems in individuals with intellectual disabilities (ID), is a shorter version of the BPI-01. This study investigated the reliability and validity of the BPI-S Japanese version (BPI-S-J) for adolescents/adults with ID and behavior problems., Methods: The test-retest reliability included participants with ID and behavioral problems who were enrolled in welfare services. For test-retest reliability, 42 caregivers independently responded to the BPI-S-J every two weeks. Inter-rater reliability was independently assessed using the BPI-S-J by two caregivers who were familiar with the 42 participants. The participants of the validity assessment were 227 students from special needs schools or patients with ID admitted to medical institutions. The total frequency total score was compared based on the degree of ID. To examine the criterion-related validity, we analyzed the total frequency score, the total score of the Criteria for Determining Severe Problem Behavior (CDSPB) and the total score of the Aberrant Behavior Checklist-Japanese version (ABC-J)., Results: The BPI-S-J of test-retest reliability was satisfactory (intra-class correlation; ICC) = 0.954), and the total score significantly (ICC = 0.721) represented good inter-rater reliability. For the validity, the BPI-S-J score of participants who had severe and profound ID was significantly higher than those who had mild and moderate ID. Significant correlations were observed between the BPI-S-J score and CDSPB score (r = 0.499), and the ABC-J score (r = 0.699), indicating adequate criterion-related validity., Conclusion: This study showed the utility of the BPI-S-J to assess behavior problems in the Japanese ID population., (Copyright © 2021 The Japanese Society of Child Neurology.

Primates form strong social bonds and depend on social relationships and networks that provide shared resources and protection critical for survival. Social deficits such as those present in autism spectrum disorder (ASD) and other psychiatric disorders hinder the individual's functioning in communities. Given that early diagnosis and intervention can improve outcomes and trajectories of ASD, there is a great need for tools to identify early markers for screening/diagnosis, and for translational animal models to uncover biological mechanisms and develop treatments. One of the most widely used screening tools for ASD in children is the Social Responsiveness Scale (SRS), a quantitative measure used to identify individuals with atypical social behaviors. The SRS has been adapted for use in adult rhesus monkeys (Macaca mulatta)-a species very close to humans in terms of social behavior, brain anatomy/connectivity and development-but has not yet been validated or adapted for a necessary downward extension to younger ages matching those for ASD diagnosis in children. The goal of the present study was to adapt and validate the adult macaque SRS (mSRS) in juvenile macaques with age equivalent to mid-childhood in humans. Expert primate coders modified the mSRS to adapt it to rate atypical social behaviors in juvenile macaques living in complex social groups at the Yerkes National Primate Research Center. Construct and face validity of this juvenile mSRS (jmSRS) was determined based on well-established and operationalized measures of social and non-social behaviors in this species using traditional behavioral observations. We found that the jmSRS identifies variability in social responsiveness of juvenile rhesus monkeys and shows strong construct/predictive validity, as well as sensitivity to detect atypical social behaviors in young male and female macaques across social status. Thus, the jmSRS provides a promising tool for translational research on macaque models of children social disorders., Competing Interests: The authors have declared that no competing interests exist.

We examined the correlation between interviewer-administered Vineland Adaptive Behavior Scale II (VABS-II) and the parent-rated Adaptive Behavior Assessment System II (ABAS-II) questionnaire in 352 participants (ages 1.5-20.8 years) with autism spectrum disorder (ASD) to determine if ABAS could be used as a screen to reduce the number of VABS interviews. Corresponding domain scores between the two measures were highly correlated but scores were significantly lower on the ABAS-II. Screening with ABAS-II significantly reduced the number of VABS-II interviews required with little cost to overall accuracy. The ABAS-II provides a cost- and time-saving alternative to the VABS-II to rule out functional impairment; however, scores are not strictly comparable between the two measures.

Unhealthy eating is associated with various diseases, such as cardiovascular, neurodegenerative, or oncological. There are neither economical nor behavior-related questionnaires available in the German language to assess general dietary behavior. Therefore, the aim of this validation study was to develop an instrument considering these aspects and verifying its construct and criterion validity. The new questionnaire is based on the general nutrition recommendations of the World Health Organization and the German Nutrition Society. It consists of 16 items that contrast dietary behaviors on a semantic differential scale. Our German-speaking convenience sample consisted of 428 participants. The construct validity of the General Dietary Behavior Inventory (GDBI) could be confirmed by examining convergent and discriminant validity. Furthermore, criterion validity was confirmed (significant negative correlations with body weight, Body Mass Index, and positive correlations with physical/mental health as well as life satisfaction). A cluster analysis revealed two different dietary behavior clusters representing a rather healthy and a rather unhealthy dietary behavior cluster. The results indicate that the GDBI is a validated and economical instrument to assess general dietary behavior. In practical research, this questionnaire helps to assess dietary behavior and to derive interventions for a healthy dietary behavior in concordance with international nutrition recommendations.

Background: Rating scales are designed to complement traditional performance-based measures, and both can provide useful information about the functioning of youth with histories of prenatal alcohol exposure. Few studies, however, have compared ratings from multiple informants or the relationship between these subjective rating scale scores and the objective results from laboratory performance-based scales., Methods: The current study addressed both of these questions in 3 study groups: children with histories of prenatal alcohol exposure (n = 47), attention-deficit/hyperactivity disorder (ADHD; n = 41), and typically developing controls (CON; n = 73). All subjects completed a standardized neuropsychological test battery, including laboratory measures of executive functioning and a self-report measure of executive function behaviors. Parents and teachers completed corresponding rating scales of executive function behaviors for each subject. This study assessed the relationship between these behavior rating scales and corresponding neuropsychological tests, and interrater agreement among the multiple informants., Results: Weak correlations were found between the rating scales and laboratory measures, indicating poor convergent validity for the behavior rating scale. Interrater reliability was found but it differed by group. Agreement was found between parent and teacher ratings for children with prenatal alcohol exposure, whereas teacher-child agreement was found for those with ADHD., Conclusions: Findings from this study indicate that behavior ratings can be used to supplement laboratory measures but may not be measuring cognitive abilities regardless of whether a clinical diagnosis is present. A multimethod approach should be used when measuring skills in this domain. This was one of the first studies to examine cross-informant agreement in a sample of children with prenatal alcohol exposure. Further research is necessary to understand why interrater agreement differed for children with prenatal alcohol exposure and those with ADHD., (© 2021 by the Research Society on Alcoholism.)

Negative symptoms are a critical, but poorly understood, aspect of schizophrenia. Measurement of negative symptoms primarily relies on clinician ratings, an endeavor with established reliability and validity. There have been increasing attempts to digitally phenotype negative symptoms using objective biobehavioral technologies, eg, using computerized analysis of vocal, speech, facial, hand and other behaviors. Surprisingly, biobehavioral technologies and clinician ratings are only modestly inter-related, and findings from individual studies often do not replicate or are counterintuitive. In this article, we document and evaluate this lack of convergence in 4 case studies, in an archival dataset of 877 audio/video samples, and in the extant literature. We then explain this divergence in terms of "resolution"-a critical psychometric property in biomedical, engineering, and computational sciences defined as precision in distinguishing various aspects of a signal. We demonstrate how convergence between clinical ratings and biobehavioral data can be achieved by scaling data across various resolutions. Clinical ratings reflect an indispensable tool that integrates considerable information into actionable, yet "low resolution" ordinal ratings. This allows viewing of the "forest" of negative symptoms. Unfortunately, their resolution cannot be scaled or decomposed with sufficient precision to isolate the time, setting, and nature of negative symptoms for many purposes (ie, to see the "trees"). Biobehavioral measures afford precision for understanding when, where, and why negative symptoms emerge, though much work is needed to validate them. Digital phenotyping of negative symptoms can provide unprecedented opportunities for tracking, understanding, and treating them, but requires consideration of resolution., (© The Author(s) 2020.

Children with severe motor and intellectual disabilities experience chronic pain but cannot communicate verbally. However, no Japanese tool currently exists for assessing pain in this population. This study aimed to develop and evaluate the reliability and validity of a Japanese version of the Paediatric Pain Profile, which is a behavioral rating scale to assess pain in children with severe neurological disabilities. The sample comprised 30 children with severe motor and intellectual disabilities at three hospitals in Japan. Three specialist nurses rated low and high pain video scenes of the children (twice at 1-week intervals) using the Face, Legs, Activity, Cry, Consolability behavioral scale and a translated Japanese version of the Paediatric Pain Profile. On the basis of their ratings, we calculated the internal consistency, test-retest reliability, and intra- and inter-observer reliabilities of the Paediatric Pain Profile. Additionally, we assessed concurrent validity using the Face, Legs, Activity, Cry, Consolability behavioral scale and construct validity using low versus high pain scenes. Both internal consistency (low pain: alpha = 0.735; high pain: alpha = 0.928) and test-retest reliability (r = 0.846) of the Japanese version of the Paediatric Pain Profile were good. Intra-observer reliability was substantial (r = 0.748), whereas inter-observer reliability was only moderate (r = 0.529). However, the concurrent validity with Face, Legs, Activity, Cry, Consolability scores was good (r = 0.629) and construct validity was confirmed (p < 0.001). We confirmed the validity of the Japanese version of the Paediatric Pain Profile, but reliable pain assessment may require repeated ratings by the same person. To accurately assess pain in children with severe motor and intellectual disabilities, healthcare staff must be properly trained and become more skilled in using the Japanese version of the Paediatric Pain Profile., Competing Interests: The authors have declared that no competing interests exist.

The purpose of this study was to support the development and initial validation of the Intervention Selection Profile (ISP)-Skills, a brief 14-item teacher rating scale intended to inform the selection and delivery of instructional interventions at Tier 2. Teacher participants (n = 196) rated five students from their classroom across four measures (total student n = 877). These measures included the ISP-Skills and three criterion tools: Social Skills Improvement System (SSIS), Devereux Student Strengths Assessment (DESSA), and Academic Competence Evaluation Scales (ACES). Diagnostic classification modeling (DCM) suggested an expert-created Q-matrix, which specified relations between ISP-Skills items and hypothesized latent attributes, provided good fit to item data. DCM also indicated ISP-Skills items functioned as intended, with the magnitude of item ratings corresponding to the model-implied probability of attribute mastery. DCM was then used to generate skill profiles for each student, which included scores representing the probability of students mastering each of eight skills. Correlational analyses revealed large convergent relations between ISP-Skills probability scores and theoretically-aligned subscales from the criterion measures. Discriminant validity was not supported, as ISP-Skills scores were also highly related to all other criterion subscales. Receiver operating characteristic (ROC) curve analyses informed the selection of cut scores from each ISP-Skills scale. Review of classification accuracy statistics associated with these cut scores (e.g., sensitivity and specificity) suggested they reliably differentiated students with below average, average, and above average skills. Implications for practice and directions for future research are discussed, including those related to the examination of ISP-Skills treatment utility., (Copyright © 2020 Society for the Study of School Psychology.

Objective: To evaluate the involvement of nod-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome in schizophrenia-like behaviour in young animals exposed to maternal immune activation (MIA)., Methods: To this aim, on the 15th gestational day, the females received an injection of lipopolysaccharides. When the animals completed 7, 14 and 45 postnatal days, they were killed and the whole brain was dissected for biochemical analysis. Animals with 45 postnatal days were submitted to behavioural tests of locomotor activity, social interaction and stereotyped movements., Results: It was observed that the animals presented schizophrenia-like behaviour at 45 postnatal days associated with the increase of NLRP3 inflammasome expression and IL-1β levels on 7, 14 and 45 postnatal days., Conclusion: This study shows that MIA may be associated with a schizophrenia-like behaviour. This behaviour can be induced to a neuroinflammatory profile in the brain. These evidences may base future studies on the relationship between neuroinflammation and psychiatric disorders.

Background: Diabetes foot self-care is one of the self-management behaviors of diabetic patients leading to a reduction in the incidence of pressure ulcers and amputation. Having a valid, reliable, simple and comprehensive tool is essential in measuring the self-care behavior of diabetic patients. The aim of this study was to evaluate the psychometric properties of the Farsi version of the diabetes foot self-care bahavior scale (DFSBS) in Iran., Methods: In this cross-sectional and methodological study, 500 patients with type 2 diabetes were recruited by convenience sampling. Construct validity was assessed by exploratory factor analysis (over 300 patients) and confirmatory factor analysis (over 200 patients). Internal consistency was calculated by Cronbach's alpha coefficient and its stability was calculated by intraclass correlation coefficient (ICC)., Results: In the exploratory factor analysis, two self-care factors related to feet and shoes were extracted which had specific values of 38.49 and 1.24, respectively, and were able to account for 56.22% of the total self-care variance of diabetes foot. Confirmatory factor analysis had excellent fit model. The internal consistency and ICC of the whole instrument were 0.83 and 0.791 (95% CI: 0.575-0.925; P < 0.001), respectively., Conclusions: The Farsi version of DFSBS (F-DFSBS) has good validity and reliability, and due to its appropriate psychometric properties, this tool can be used in future studies.

The Conners' Continuous Performance Test-Second Edition (CCPT-2) is a widely used measure of attention and impulsivity, however, only a minimal amount is known about its reliability. To clarify the psychometric properties of the CCPT-2, we assessed its performance stability and related it to criterion measures. A total of 91 undergraduate students completed the CCPT-2, the State-Trait Personality Inventory (STPI), and reported on sleep during two sessions approximately one week apart. They completed the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) at session one and the Stroop Color and Word Test at session two. Findings indicated that the CCPT-2 had strong internal consistency, adequate test-retest reliability for commission errors and response time, poor test-retest reliability for omission errors, and practice effects for omission and commission errors. The CCPT-2 was largely unrelated to the BRIEF-A, Stroop Color and Word Test, and the STPI. More sleep was related to a quicker response time and more commission errors on the CCPT-2, and the BRIEF-A's Behavior Regulation Index was positively related to commission errors. Relative to the omission error component of the CCPT-2, commission errors and response time may be useful and stable measures of sustained attention and impulsivity.

Direct Behavior Rating (DBR) is a tool designed for the assessment of behavioral changes over time. Unlike methods for summative evaluations, the development of progress monitoring tools requires evaluation of sensitivity to change. The present study aimed to evaluate this psychometric feature of five newly developed DBR Multi-Item Scales (DBR-MIS). Teachers identified students with behaviors interfering with their learning or the learning of others and implemented a Daily Report Card (DRC) intervention in the classroom settings for two months. The analyses were performed on 31 AB single case studies. Change metrics were calculated at an individual level by using Tau-U A vs. B + trend B and Hedges' g and at a scale-level by using Mixed Effect Meta-Analysis, Hierarchical Linear Models (HLMs), and Between-Case Standardized Mean Difference (BC-SMD). HLMs were estimated considering both fixed and random effects of intervention and linear trend within the intervention phase. The results supported sensitivity to change for three DBR-MIS (i.e., Academic Engagement, Organizational Skills, and Disruptive Behavior), and the relative magnitudes were consistent across the metrics. Sensitivity to change of DBR-MIS Interpersonal Skills received moderate support. Conversely, empirical evidence was not provided for sensitivity to change of DBR-MIS Oppositional Behavior. Particular emphasis was placed on the intervention trend in that responses to behavioral interventions might occur gradually or require consistency over time in order to be observed by raters. Implications for the use of the new DBR-MIS in the context of progress monitoring of social-emotional behaviors are discussed., (Copyright © 2020 Society for the Study of School Psychology.

Behavioral development in domestic dogs has been investigated for predicting suitability for service dog work or for matching with the "right" families as well as for identifying predispositions to behavioral problems. Findings from the scientific literature seem to confirm that conducting behavioral tests at 7 weeks of age is too early to reliably predict the temperament and personality of a dog. However, this period for domestic dogs is sensitive for early life learning and conditions during this time could have important consequences in adulthood. The aims of this study were to evaluate inter-rater reliability of a simple standardized test and to investigate which factors influence the behavioral reaction of puppies. 105 seven-week old puppies were exposed to five subtests: social attraction, following, retrieving, sudden appearance, noise. During each task, the behaviour of each pup was scored on a 3-5 point scale that reflected the suitability of the pup's reaction to the task. Scores were evaluated for a single subtest and for two aggregate indicators (i.e. response to a person: social attraction subtest and following subtest and response to object and noise: retrieving subtest, sudden appearance subtest and noise subtest). Three assessors independently scored the dogs' reactions for each task. Inter-rater reliability of the three assessors were analyzed with Fleiss' Kappa and Kendall's coefficient, which showed a high inter-rater reliability in 4 of 5 tasks. The ordered logistic regression was carried out to obtain a proportional odds model that was used to model the relationship between sex, litter size, stimulating environment, parity of mother, adequate maternal behavior and high scores. Litter size and maternal parity were associated with test performance in response to a person. The variance of effect of litter was high in response to object and noise. Taken together, our results suggest that using this scoring system there is sufficient inter-rater reliability in the test and litter size and mother experience influences task performances related to dog-human interaction., Competing Interests: The authors have declared that no competing interests exist.

Significant advancements have been made in early intervention programs for children with Autism spectrum disorder (ASD). However, measuring treatment response for children with ASD is difficult due to the heterogeneity of changes in symptoms, which can be subtle, especially over a short period of time. Here we outline the challenge of evaluating treatment response with currently available measures as well as newly developed or refined measures that may be useful in clinical trials for young children with ASD. Continued development of treatment outcome measures will help the field identify and compare efficacious interventions and tailor treatments for children with ASD., (Copyright © 2020 Elsevier Inc.

There is growing interest in using telehealth to work with people with traumatic brain injury (TBI). This study investigated whether established rating scales for evaluating conversations of people with TBI are reliable for use over videoconferencing. Nineteen participants with TBI and their communication partners completed two conversation samples during both in-person (IP) and videoconferencing-based (VC) assessment, with randomised order of assessment. Independent clinicians evaluated the conversations using the Adapted Measure of Participation in Conversation (MPC), the Adapted Measure of Support in Conversation (MSC) and the Global Impression scales. Comparisons between IP and VC ratings identified no significant differences on the MPC, MSC, and four out of five of the Global Impression scales. There was a significant difference between IP and VC recordings for "Task Completion" ( p  = .047), with participants performing significantly better in VC ratings. Inter-rater reliability was fair to excellent for the MPC and Global Impression scales for both IP and VC recordings. For the MSC scale, inter-rater reliability was poor to excellent. This study confirms the potential for using videoconferencing for evaluating conversations of people with TBI. Further development of training and rating procedures for these scales could facilitate more frequent and reliable use of these measures.

Objective: The present study aimed to investigate the validity and reliability of the Persian version of brief self-control scale (BSCS) in Iranian motorcyclists. Methods: The original English questionnaire of BSCS has been translated into Persian using the direct-reverse approach. A total of 130 motorcyclists aged 18-65 years old in Iran-Kashan completed the questionnaire. Validity was determined by content validity methods, structural validity through factor analysis, and also the convergence and divergence validity using Spearman correlation coefficient. The intra class correlation coefficient (ICC) was calculated to estimate the reliability of the self-control tool. Reliability was calculated using Cronbach's alpha. Results: The mean and standard deviation of the age at the time of study was 38.5 ± 13.5 years old and all of the subjects were male. Cronbach's alpha coefficient of the whole questionnaire (BSCS) was 0.81, which was good in this regard. The ICC coefficient was 0.88 with confidence interval of (0.8-0.93), which confirmed the repeatability of this tool. Exploratory factor analysis (EFA) yielded a two-factor solution accounted for 42% of the observed variance. Conclusion: This study showed that Persian version of BSCS has a good reliability and validity for self-control in the Persian language community.Key pointsThe Brief Self-Control Scale (BSCS) has good internal consistency.The Brief Self-Control Scale (BSCS) has acceptable reliability.Brief Self-control Scale (BSCS) has acceptable validity and reliability in the population studies.

As schools increasingly adopt universal social, emotional, and behavioral screening, more research is needed to examine the effects of between-teacher differences due to error and bias on students' teacher-rated screening scores. The current study examined predictors of between-teacher differences in students' teacher-rated risk across one global and three narrow domains of behavioral functioning. Participants included 2450 students (52.1% male, 54.2% White) and 160 teachers (92.1% female, 80.3% White) from four elementary schools in one Southeastern U.S. school district. Teachers rated student behavior on the Behavior Assessment System for Children (Third Edition) Behavioral and Emotional Screening System (BESS)-Teacher Form and completed a survey about their training and perspectives of common behavior problems. Results of multilevel linear regression found between-teacher effects to be greater for internalizing risk scores (intraclass correlation = 0.23) than for externalizing risk scores (intraclass correlation = 0.12) or adaptive behavior scores (intraclass correlation = 0.14). Statistically significant student predictors in most models included student grade, gender, race and/or ethnicity, office discipline referrals, and course grades. We also detected effects of several teacher-level variables in one or more of the models, including teacher gender, teacher ratings of problem severity and concern for hypothetical children displaying behavior problems, and the covariance of random teacher intercept and teacher random slopes for students' office discipline referrals. Although these factors explained some teacher-level variance in students' risk scores, a notable amount of variance between teachers remains unexplained. Future research is needed to fully understand, reduce, and account for differences between teacher ratings due to error and bias., Competing Interests: Declaration of competing interest None., (Copyright © 2020 Society for the Study of School Psychology.

The Nociception Coma Scale-Revised (NCS-R) was developed to help assess pain in patients with disorders of consciousness (DOC). Several studies have shown its sensitivity in assessing response to acute noxious stimuli. However, they failed to determine a reliable cut-off score that could be used to infer pain processing in these patients. This retrospective cross-sectional study aimed to determine a NCS-R cut-off score supporting preserved neural basis for pain experience, based on brain metabolism preservation as measured by fluorodeoxyglucose positron emission tomography (FDG-PET). We included patients in unresponsive wakefulness syndrome (UWS) confirmed by the FDG-PET and examined the NCS-R total scores. As the highest score was 4, we defined the cut-off to be 5 and compared the brain metabolism of these patients to matched patients with DOC and a NCS-R cut-off score ≥5 (ie, potential pain), as well as healthy subjects. We found a higher global cerebral metabolism in healthy subjects compared to both patient groups and also in patients with potential pain compared with FDG-PET confirmed UWS. We observed a preserved metabolism in the left insula in patients with potential pain compared with FDG-PET confirmed UWS. PERSPECTIVES: Our data suggest that using the cut-off score of 5 could be helpful to improve pain management in patients with DOC. Future studies should focus on patients showing scores below this cut-off to better characterize their profile and improve care., (Copyright © 2019 United States Association for the Study of Pain, Inc.

The aim of this study was to develop and validate the Childhood Nonverbal Communication Scale (CNCS) to assess nonverbal communication skills in children from birth to 18 months old. An extensive review of existing research provided evidence used to generate items representative of nonverbal communication behaviors. The final version of the CNCS includes 37 items divided in two dimensions (CNCS-1 and CNCS-2) showing high content validity (item-rated content validity index ≥ 0.75). The scale was administered to 428 Iranian Persian-speaking children 3 to 18 months old with normal development. According to the findings, the CNCS showed strong internal consistency (KR-20 = 0.965). Further, it had good convergent validity based on a significant correlation between total scores and the results of the Persian version of the Production of Infant Scale Evaluation (PRISE-P) (r = 0.5, P < 0.01). Therefore, the CNCS is a promising tool for measuring nonverbal communication in Iranian children from birth to 18 months of age.

Given the importance of competencies in functional behavior assessment (FBA) and behavioral interventions among teachers for managing problem behaviors among children with autism spectrum disorder (ASD) and other developmental disabilities, a previously reported ability in behavior assessment and interventions for teachers (ABAIT) needed improvements in the multiple-choices by adding a 'don't know' option. This study reports on the psychometric properties of this revised scale (ABAIT-R) among 102 special educators assessed using Rasch models. It was found that the model had good fit and a wide spread of difficulties (3.63 to - 2.60). ABAIT-R had good targeting (over 85%) and high reliability (0.79). The assumptions of the model were met recommending sufficiency for the use of summated score from ABAIT-R among teachers.

The Cohen-Mansfield Agitation Inventory was a tool originally developed for use in research to measure agitation and subsequently used in clinical settings. It was the primary outcome measure for a randomised controlled trial which evaluated the effects and feasibility of a physiotherapist-led physical exercise intervention on agitation and physical performance of individuals living with dementia in nursing homes. The study produced weak results in regards to the Cohen-Mansfield Agitation Inventory due to small sample size and perceived issues with the use of the Cohen-Mansfield Agitation Inventory. Therefore, the focus of this paper is consideration of the identified issues by the research team: learnt effect and Hawthorn effect, misunderstanding of behaviours and inaccurate recall and observation. It is important that tools originally developed for research are still valid and reliable in the clinical setting.

Early intervention (EI) therapy services aim to address family-centered goals to facilitate young children's development and participation in meaningful life activities. Current methods to evaluate children in EI assess discrete developmental skills but provide little information on the child's ability to successfully incorporate that skill in everyday life. Furthermore, traditional measures have limited opportunity for parent report, despite parent engagement being a critical component for successful implementation of EI services. A measure that involves parents in the therapeutic process to track family-driven EI goals related to a child's occupational engagement in meaningful family activities and routines is desperately needed. Using a qualitative design and conventional content analysis, we identified 41 distinct activities of infant-toddlers from a cohort of 23 caregivers. Activity items were matched with photographs and validated with experts in pediatric rehabilitation using the Delphi method. The resulting 40 activity/photograph pairs were used to develop a new measure of pediatric occupational engagement, the Infant Toddler Activity Card Sort (ITACS).

Aim: Utena's Brief Objective Measures (UBOM) was developed to assess psychophysiological functions proximal to real-world functioning in individuals with psychiatric disorders, including schizophrenia (SCZ), to facilitate shared decision-making. However, the validity of UBOM has not been fully examined., Methods: We conducted a cross-sectional observational study to evaluate the validity of each of the three tests in UBOM: UBOM-Pulse, UBOM-Ruler, and UBOM-Random. We investigated associations: (i) between UBOM and existing cognitive- and autonomic-function tests; and (ii) between UBOM and daily social functioning. The participants included SCZ individuals and healthy controls. We evaluated the cognitive and autonomic function using UBOM, the heart rate variability test, the simple reaction time test, and the Brief Assessment of Cognition in Schizophrenia, Japanese version. We also assessed the daily social functioning using the WHO Disability Assessment Schedule 2.0 and the modified Global Assessment of Functioning, Japanese version., Results: Thirty-one SCZ individuals and 35 healthy control individuals participated in this study. In the SCZ group, UBOM-Ruler was significantly associated with the Cognition and Getting Along domains of WHO Disability Assessment Schedule 2.0. UBOM-Random was significantly associated with the Brief Assessment of Cognition in Schizophrenia's Working Memory, Verbal Fluency and Attention domains, and the modified Global Assessment of Functioning in the SCZ group., Conclusion: The validity of the current version of UBOM is imperfect and further improvements will be necessary to attain the originally intended goal of developing a brief assessment tool for real-world functioning in SCZ., (© 2019 The Authors.

Background: Signs of autism are present in the first 2 years of life, but the average age of diagnosis lags far behind. Instruments that improve detection of autism risk in infancy are needed. This study developed and tested the psychometric properties of a novel video-based approach to detecting ASD in infancy., Methods: A prospective longitudinal study of children at elevated or lower risk for autism spectrum disorder was conducted. Participants were 76 infants with an older sibling with ASD and 37 infants with no known family history of autism. The Video-referenced Infant Rating System for Autism (VIRSA) is a web-based application that presents pairs of videos of parents and infants playing together and requires forced-choice judgments of which video is most similar to the child being rated. Parents rated participants on the VIRSA at 6, 9, 12, and 18 months of age. We examined split-half and test-retest reliability; convergent and discriminant validity; and sensitivity, specificity, and negative and positive predictive value for concurrent and 36-month ASD diagnoses., Results: The VIRSA demonstrated satisfactory reliability and convergent and discriminant validity. VIRSA ratings were significantly lower for children ultimately diagnosed with ASD than children with typical development by 12 months of age. VIRSA scores at 18 months identified all children diagnosed with ASD at that age, as well as 78% of children diagnosed at 36 months., Conclusions: This study represents an initial step in the development of a novel video-based approach to detection of ASD in infancy. The VIRSA's psychometric properties were promising when used by parents with an older affected child, but still must be tested in community samples with no family history of ASD. If results are replicated, then the VIRSA's low-burden, web-based format has the potential to reduce disparities in communities with limited access to screening., (© 2019 Association for Child and Adolescent Mental Health.)

With the growing popularity of online services such as online banking and online shopping, one of the essential research topics is how to build a privacy-preserving user abnormal behavior recommendation system. However, a machine-learning based system may present a dilemma. On one aspect, such system requires large volume of features to pre-train the model, but on another aspect, it is challenging to design usable features without looking to plaintext private data. In this paper, we propose an unorthodox approach involving graph analysis to resolve this dilemma and build a novel private-preserving recommendation system under a multilayer network framework. In experiments, we use a large, state-of-the-art dataset (containing more than 40,000 nodes and 43 million encrypted features) to evaluate the recommendation ability of our system on abnormal user behavior, yielding an overall precision rate of around 0.9, a recall rate of 1.0, and an F1-score of around 0.94. Also, we have also reported a linear time complexity for our system. Last, we deploy our system on the "Wenjuanxing" crowd-sourced system and "Amazon Mechanical Turk" for other users to evaluate in all aspects. The result shows that almost all feedbacks have achieved up to 85% satisfaction., Competing Interests: The corresponding author (Weiyi Liu) is an employee in JD Urban computing business unit.

Objectives: This study aims to ascertain whether the differences of prevalence and severity of attention deficit hyperactivity disorder (ADHD) are true or whether children are perceived and rated differently by parent and teacher informant assessments (INFAs) according to gender, age, and co-occurring disorders, even at equal levels of latent ADHD traits., Methods: Use of latent trait models (for binary responses) to evaluate measurement invariance in children with ADHD and their siblings from the International Multicenter ADHD Gene data., Results: Substantial measurement noninvariance between parent and teacher INFAs was detected for seven out of nine inattention (IA) and six out of nine hyperactivity/impulsivity (HI) items; the correlations between parent and teacher INFAs for six IA and four HI items were not significantly different from zero, which suggests that parent and teacher INFAs are essentially rating different kinds of behaviours expressed in different settings, instead of measurement bias. However, age and gender did not affect substantially the endorsement probability of either IA or HI symptom criteria, regardless of INFA. For co-occurring disorders, teacher INFA ratings were largely unaffected by co-morbidity; conversely, parental endorsement of HI symptoms is substantially influenced by co-occurring oppositional defiant disorder., Conclusions: Our findings suggest general robustness of Diagnostic and Statistical Manual of Mental Disorders ADHD diagnostic items in relation to age and gender. Further research on classroom presentations is needed., (© 2019 John Wiley & Sons, Ltd.)

Researchers worldwide have developed and validated several scales to assess various forms of adults' digital addiction. The urge for some of these scales found support in World Health Organization's inclusion of gaming disorder as a mental health condition in its eleventh revision of the International Classification of Diseases in June 2018. Additionally, several studies have shown that children are starting to use digital devices (DDs) (e.g., tablets and smartphones) at a very young age, including playing video games and engaging in social media. Consequently, the need for early detection of the risk of digital addiction among children is becoming more of a necessity. In the present study, the Digital Addiction Scale for Children (DASC)-a 25-item self-report instrument-was developed and validated to assess the behavior of children 9 to 12 years old in association with DD usage, including video gaming, social media, and texting. The sample comprised 822 participants (54.2 percent males), from grade 4 to grade 7. The DASC showed excellent internal consistency reliability (α = 0.936) and adequate concurrent and criterion-related validities. The results of the confirmatory factor analysis showed that the DASC fitted the data very well. The DASC paves the way to (a) help in early identification of children at risk of problematic use of DDs and/or becoming addicted to DDs and (b) stimulate further research concerning children from different cultural and contextual settings.

Objectives: In this study, we examined the consequences of ignoring violations of assumptions underlying the use of sum scores in assessing attention problems (AP) and if psychometrically more refined models improve predictions of relevant outcomes in adulthood., Methods: Tracking Adolescents' Individual Lives data were used. AP symptom properties were examined using the AP scale of the Child Behavior Checklist at age 11. Consequences of model violations were evaluated in relation to psychopathology, educational attainment, financial status, and ability to form relationships in adulthood., Results: Results showed that symptoms differed with respect to information and difficulty. Moreover, evidence of multidimensionality was found, with two groups of items measuring sluggish cognitive tempo and attention deficit hyperactivity disorder symptoms. Item response theory analyses indicated that a bifactor model fitted these data better than other competing models. In terms of accuracy of predicting functional outcomes, sum scores were robust against violations of assumptions in some situations. Nevertheless, AP scores derived from the bifactor model showed some superiority over sum scores., Conclusion: These findings show that more accurate predictions of later-life difficulties can be made if one uses a more suitable psychometric model to assess AP severity in children. This has important implications for research and clinical practice., (© 2019 The Authors International Journal of Methods in Psychiatric Research Published by John Wiley & Sons Ltd.)

This study used item response theory (IRT) to derive sets of maximally efficient items (SMI) for a brief behavior rating scale (BBRS) from a common universal screening tool (i.e., the Social, Academic, and Emotional Behavior Risk Screener-Student Rating Scale [mySAEBRS]). We also evaluated the change sensitivity of these items for potential use in progress monitoring. Data from over 24,000 students (47% female; 40% White; 17% African American; 7% Hispanic) in Kindergarten through 12th grades were included in the first phase of analyses. A subsample of 774 students (43% female; 33% White; 3% African American; 0.5% Hispanic) was included in the change sensitivity analyses. Results suggested 3 items from each of the SAEBRS subscales (Social Behavior, Academic Behavior, and Emotional Behavior) could be considered maximally efficient and psychometrically informative. Additionally, change sensitivity analyses across the SMIs offered some evidence for the development of brief, 3-item standard BBRSs for use in progress monitoring students with social, academic, and emotional behavioral challenges. More research is needed to examine whether using BBRSs result in meaningful behavioral and social emotional change, particularly for specific demographic subgroups.

Purpose: Executive functions (EF) are high-order cognitive skills that have a major influence on quality of life, social skills, and school achievement. We aimed to screen EF daily life abilities in young patients with myoclonic-atonic epilepsy (MAE) using an ecological questionnaire and to correlate EF to epilepsy characteristics., Methods: Behavioral Rating Inventory of Executive Functions - Preschool (BRIEF-P) and BRIEF - for school-aged patients - parental questionnaires were proposed to patients with MAE and typically developing children (TDC) including Inhibit, Shift, Emotional control, Working memory (WM), Plan/Organize, Initiate, Organization of materials, and Monitor subscales. We included prospectively 12 patients with MAE and 44 TDC aged 3 to 5 years and seven patients with MAE and 21 TDC aged 6-7 years. We performed in addition for all patients an intellectual efficiency evaluation using WPPSI-IV (Wechsler intelligence scale for preschool children version IV) and collected demographics, age at onset of epilepsy, epilepsy duration, response to treatment, number and type of treatments including AEDs (antiepileptic drugs), and ketogenic diet., Results: Four out of 12 patients for BRIEF-P and 6/7 patients for BRIEF had pathological scores for at least one domain. Behavioral Rating Inventory of Executive Functions' questionnaires showed higher pathological scores for WM, Plan/Organize, Initiate, Monitor, and Metacognition Index in patients with MAE compared to TDC suggesting higher problems reported by parents. Working memory scores were higher in the group with MAE than TDC for both BRIEF-P and BRIEF. Response to treatment is a predictor of multiple BRIEF-P domains. Epilepsy duration predicts Shift and WM domains while age at onset predicts WM domain on BRIEF in this syndrome., Conclusions: This study is the first to assess prospectively EF in young patients with MAE. We show everyday deficits in EF reported by parents. Metacognition and more specifically WM, appear to be a core deficit. Early evaluation of EF using both questionnaires and standardized tools is necessary for early detection of EF deficit and initiating tailored rehabilitation. Given the normal development before seizure onset and the absence of cerebral lesion in MAE, these results are in favor of the impact of epilepsy on EF., (Copyright © 2019.

The Conners' Rating Scales are widely used to assess attention deficit/hyperactivity disorder (ADHD) and related difficulties in children and adolescents. A short form of the scales is available, which, along with the several advantages of brief versions, also displays good psychometric properties. Nonetheless, no studies have confirmed them in cultural contexts different from the original one. The present study examined the psychometric properties of the Self-Report, Parent, and Teacher Conners 3-Short Forms in terms of reliability and validity in an Italian sample. Analyses were performed on 591 children and adolescents, 631 parents' ratings, and 325 teachers' ratings. To test for discriminative validity, ADHD clinical samples of 55 youth, 63 parents, and 15 teachers were compared to gender- and age-matched groups. Findings confirmed the original multidimensional structures and supported the Conners 3-Short Form scales as reliable and valid tools to assess ADHD and its main comorbid conditions.

Background: Population-based samples with valid, quantitative and genetically informative trait measures of psychopathology could be a powerful complement to case/control genetic designs. We report the convergent and predictive validity of the parent- and self-report versions of the Strengths and Weaknesses of ADHD Symptoms and Normal Behavior Rating Scale (SWAN). We tested if SWAN scores were associated with ADHD diagnosis, ADHD polygenic risk, as well as traits and polygenic risk for disorders that co-occur with ADHD: anxiety and obsessive-compulsive disorder (OCD)., Methods: We collected parent- and self-report SWAN scores in a sample of 15,560 children and adolescents (6-17 years) recruited at a science museum (Spit for Science sample). We established age and sex norms for the SWAN. Sensitivity-specificity analyses determined SWAN cut-points that discriminated those with and without a reported ADHD diagnosis. These cut-points were validated in a clinic sample (266 ADHD cases; 36 controls). Convergent validity was established using the Conners' parent- and self-report scales. Using Spit for Science participants with genome-wide data (n = 5,154), we tested if low, medium and high SWAN scores were associated with polygenic risk for ADHD, OCD and anxiety disorders., Results: Parent- and self-report SWAN scores showed high convergent validity with Conners' scales and distinguished ADHD participants with high sensitivity and specificity in the Spit for Science sample. In a clinic sample, the Spit for Science cut-points discriminated ADHD cases from controls with a sensitivity of 84% and specificity of 92%. High SWAN scores and scores above the Spit for Science cut-points were significantly associated with polygenic risk for ADHD. SWAN scores were not associated with polygenic risk for OCD or anxiety disorders., Conclusions: Our study supports the validity of the parent- and self-report SWAN scales and their potential in ADHD population-based genetic research., (© 2019 Association for Child and Adolescent Mental Health.)

The purpose of this study was to evaluate the reliability, validity, and accuracy of scores from the Intervention Selection Profile-Function (ISP-Function): a brief functional assessment tool founded upon Direct Behavior Rating (DBR) methodology. Participants included 34 teacher-student dyads. Using the ISP-Function, teachers rated the extent to which students exhibited disruptive behavior, as well as the frequency with which disruptions were met with four consequences. Ratings were completed across three 10-min sessions, during which a research assistant also collected systematic direct observation (SDO) data regarding the same behavior and consequences. Results indicated adequate temporal reliability (≥.70) was attained for the adult attention and peer attention targets across the three ratings; in contrast, up to 8-18 data points would be needed to achieve adequate reliability across the remaining targets. Findings further suggested that while ISP-Function ratings of disruptive behavior, adult attention, and peer attention were moderately to highly correlated with SDO data, correlations were in the low range for the access to items/activities and escape/avoidance targets. Finally, analysis of difference scores showed that on average, mean ISP-Function scores fell within only 0.33 to 1.81 points of mean SDO scores (on the 0-10 DBR scale). Agreement coefficients indicative of exact score agreement were less consistent, suggesting accuracy ranged from poor to substantial. Results are promising, but future research is necessary to support applied ISP-Function use. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Background: Interventionists commonly identify promising messages for health communication efforts based on audience members' ratings of perceived message effectiveness (PME)., Purpose: We sought to validate a new PME measure that improved on existing scales by focusing on the behavior and respondent, being brief, and having strong psychometric properties., Methods: Participants were a national convenience sample of 999 adults and national probability samples of 1,692 adults and 869 adolescents recruited in 2015. Smokers and nonsmokers rated up to six brief messages about the chemicals in cigarette smoke on two PME scales. The first was the new three-item University of North Carolina (UNC) PME Scale that assessed effects perceptions. The second was an established six-item PME scale that assessed message perceptions. We examined the UNC PME Scale's psychometric properties and compared both scales using item factor analysis., Results: The UNC PME Scale measured the same construct across multiple chemical messages (all factor loadings ≥ 0.86). It exhibited high reliability (>0.85) over very low to moderate levels of PME (z = -2.5 to 0.2), a range that is useful for identifying more promising messages. Samples of adults and adolescents showed a similar pattern of results. As expected, the UNC PME Scale was strongly positively correlated with message perceptions (r = .84). It also exhibited strong psychometric properties among participants regardless of education, reactance, sex, and smoking status., Discussion: The UNC PME Scale reliably and validly measured PME among adults and adolescents from diverse groups. This brief scale may be used to efficiently evaluate candidate antismoking messages and may be suitable for adaptation to other health risk behaviors., (© Society of Behavioral Medicine 2018.

Objectives: To describe the development and psychometric properties of the 2014 Ontario Child Health Study Emotional Behavioural Scales (OCHS-EBS) for dimensional measurement of 7 disorders based on criteria from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders ( DSM-5 )., Methods: Scale items were selected by agreement among 19 child psychologists and psychiatrists rating the correspondence between item descriptions and DSM-5 symptoms. Psychometric evaluation of the item properties and parent/caregiver and youth scales came from a general population study of 10,802 children and youth aged 4 to 17 years in 6537 families. Test-retest reliability data were collected from a subsample of 280 children and their caregivers who independently completed the OCHS-EBS checklist on 2 occasions 7 to 14 days apart. Structural equation modelling was used to assess internal and external convergent and discriminant validity-the latter tested against the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID)., Results: Confirmatory factor analyses exhibited adequate item fit to all scales. Except for conduct disorder and youth-assessed separation anxiety disorder, internal (Cronbach's α) and test-retest reliability (Pearson's r ) for scale scores were 0.70 or above. Except for youth-assessed conduct disorder, the OCHS-EBS met criteria for internal and convergent and discriminant validity. Compared with the MINI-KID, the OCHS-EBS met criteria for external convergent and discriminant validity., Conclusions: The OCHS-EBS provide reliable and valid dimensional measurement of 7 DSM-5 disorders assessed by caregivers and youth in the general population. Part II describes use of the OCHS-EBS as a categorical (present/absent) measure of disorder.

Objectives: To compare the reliability and convergent validity of parent assessments from the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID - a structured diagnostic interview) and the Ontario Child Health Study Emotional Behavioural Scales (OCHS-EBS) symptom checklist for classifying conduct disorder (CD), conduct disorder or oppositional defiant disorder (CD-ODD), attention-deficit hyperactivity disorder (ADHD), major depressive disorder (MDD), generalized anxiety disorder (GAD), and separation anxiety disorder (SAD) based on DSM-5 criteria., Methods: Data came from 283 parent-youth dyads aged 9 to 18 years. Parents and youth completed the assessments separately on 2 different occasions 7 to 14 days apart. After converting the OCHS-EBS scale scores to binary disorder classifications, we compare test-retest reliability estimates and use structural equation modelling (SEM) to compare estimates of convergent validity for the same disorders assessed by each instrument., Results: Average test-retest reliabilities based on κ were 0.71 (MINI-KID) and 0.67 (OCHS-EBS). The average β coefficients for 3 latent measures comprising the following indicators-parent perceptions of youth mental health need and impairment, diagnosis of specific disorders based on health professional communications and youth taking prescribed medication, and youth classifications of disorder based on the MINI-KID-were 0.67 (MINI-KID) and 0.69 (OCHS-EBS)., Conclusion: The OCHS-EBS and MINI-KID achieve comparable levels of reliability and convergent validity for classifying child psychiatric disorder. The flexibility, low cost, and minimal respondent burden of checklists for classifying disorder make them well suited for studying disorder in the general population and screening in clinical settings.

The comparative study of animal personality has received great interest in recent years. Some studies have analyzed personalities in cetaceans (exclusively in dolphins), but none have analyzed the factorial structure of personality of any species in this order. Our objective was to evaluate a sample of captive killer whales (n = 24) adapting one of the most widely used models of personality in humans and nonhuman animals: the five-factor model. A total of 38 personality descriptive adjectives were rated by 55 raters (mainly trainers and curators). Principal components analysis and regularized exploratory factor analysis revealed four statistically significant factors with acceptable standards of interrater reliability and validity, accounting for 49.85% of the variance. The first factor indicated an Extraversion factor, the second one revealed a combined factor of Conscientiousness and Agreeableness, the third one yielded in a Dominance factor, and the fourth one reflected a Careful factor very close to a combination of Conscientiousness and Agreeableness factor. The results were compared with the results obtained for humans and chimpanzees in prior studies. The similarities could be explained as a result of convergent adaptive traits despite a deep evolutionary divergence, adaptation to physically dissimilar environments, and very different neuroanatomical organization.

This study examined informant discrepancies for parent and teacher adaptive behavior ratings of 103 children, ages 6-12 years, with ASD (without intellectual disability). Scores on the Adaptive Behavior Assessment System, third edition (Harrison and Oakland, Western Psychological Services, Los Angeles, 2015) General Adaptive Composite (GAC) and practical, social, and conceptual domains were examined for mean differences, level of agreement, and moderators of difference scores between informant groups. Teacher scores were significantly higher (indicating better functioning) than parents for the GAC and practical domain. Parent and teacher scores were moderately correlated and Bland-Altman plots and regression analyses revealed no systematic differences in parent-teacher agreement across the range of scores. None of the tested variables moderated the parent-teacher difference scores. Implications for clinical practice are discussed.

We determined inter-rater agreement for the VB-MAPP, an instrument sometimes used in planning educational goals and evaluating intervention effects for young people with autism. A pair of raters independently rated each of 32 children diagnosed with autism. Intraclass correlation coefficients for the total Milestones and Barrier scores were 0.876 and 0.629, respectively, indicating good and moderate reliability. There was variability in reliability in the different domains of the Milestones Assessment, with most indicating moderate reliability, and most of the individual Barriers Assessment domains indicating poor reliability. These are the first data relevant to the reliability of the VB-MAPP, they suggest that further evaluation of its reliability is merited and that a high reliability for individual domains should not be assumed.

The current study evaluates the psychometric properties of the Behavior Rating Inventory of Executive Function (BRIEF) with children with Down syndrome. Caregivers of 84 children with Down syndrome rated their child's behavior with the BRIEF. Teacher ratings were obtained for 57 children. About 40% of children with Down syndrome were reported by parents, and 70% by teachers, to exhibit clinically significant challenges with executive functioning. Distribution of scores was normal, internal consistency for subscales was questionable to primarily excellent, and inter-rater reliability was poor to good. Normative data conversions controlled for age, IQ, and gender differences, with some exceptions. The study findings suggest that the BRIEF and its subscales generally performed in a psychometrically sound manner among children with Down syndrome.

Although social communication skills are commonly delayed in children with neurogenetic syndromes (NGS), skill profiles in very young children are largely under characterized, in part due to the lack of validated assessment measures appropriate for these populations. We addressed this gap by validating and applying a popular early social communication screening measure, the Communication and Symbolic Behavior Scales Developmental Profile - Infant-Toddler Checklist (CSBS-ITC) in three previously understudied neurogenetic groups: Angelman, Prader-Willi, and Williams syndromes. Our results suggest that when used within the appropriate scope of screening and surveillance, the CSBS-ITC detects meaningful variability in skills across ages in young children with NGS and may provide useful information about both individual- and population-level social communication profiles in these populations.

Objective: The risk for the development of severe behaviour problems by individuals with intellectual disability (ID) is a well-known concern. However, there are currently no reliable instruments for assessing these behaviours in French. The Behaviour Problems Inventory - Short Form (BPI-S) assesses these three types of behaviour in people with ID: self-injurious behaviour (eight items), aggressive/destructive behaviours (10 items) and stereotypic behaviours (12 items). The purpose of this study was to conduct a psychometric study of a French version of the BPI-S., Method: Data were collected on 305 children, adolescents and young adults with ID 50 care workers in seven specialised institutions in France as informants. We examined the scale's factorial structure (using confirmatory factor analysis), internal consistency and inter-rater reliability. We also established preliminary French norms., Results: Our results show that the French BPI-S has a factorial structure similar to that of the English version. It has good internal consistency. The internal consistency of the frequency ratings was 0.91 and 0.62 for the severity ratings. The BPI-S has a good inter-rater reliability with acceptable coefficients for the frequency ratings (Self Injurious Behaviour (SIB) = 0.81; Aggressive-Destructive behaviour = 0.66; Stereotyped behaviours = 0.75) and for the severity ratings (SIB = 0.92; Aggressive-Destructive behaviour = 0.54). The data also show that the frequency and severity of behaviours differ based on the level of ID., Conclusions: The French version of the BPI-S has good psychometric properties for assessing problem behaviours in children, adolescents and young adults. This scale can be used for research and clinical evaluation of disorders associated with ID., (© 2019 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.)

Objective: The Strengths and Weaknesses of ADHS-Symptoms and Normal Behavior (SWAN) Scale has been developed to support the dimensional assessment of ADHD symptoms by capturing variance on both poles of the ADHD continuum. The present study provides the first validation of the German version of SWAN (SWAN-DE)., Method: Based on a sample of N 1 = 343 children from the general population and N 2 = 62 children with ADHD, both aged between 8 and 18 years, normality, internal consistency, test-retest reliability, and different validity indices were examined., Results: SWAN was characterized by normally distributed scores, good to excellent reliability, and factorial validity. It showed high diagnostic utility in discriminating between patients with ADHD and healthy controls and significant correlations to related clinical scales and neuropsychological constructs, such as intra-subject variability., Conclusion: The present study reveals the excellent psychometric properties of SWAN-DE, which can now be usefully applied in the German-speaking countries as well as in cross-national studies.

Universal screening for behavioral/mental health risk is a critical component of multitiered systems of support, allowing for early identification of students in need of prevention and/or intervention services. The Student Risk Screening Scale (SRSS; Drummond, 1994) is one commonly used universal screening tool intended to measure externalizing behavior difficulties. Although the reliability and criterion-related validity of the SRSS has been studied extensively, there are limited data supporting its construct validity. To this end, the current study investigated the internal structure of the SRSS and the degree to which it demonstrated measurement invariance across time (i.e., fall, winter, spring) and gender (i.e., male, female). Fifty-five teachers completed the SRSS for 1,220 students in kindergarten through 5th grade across three elementary schools during fall, winter, and spring benchmarking periods. Results of a confirmatory factor analysis provided support for the SRSS as a single-factor measure of externalizing behavior difficulties. Results of multigroup confirmatory factor analyses supported its measurement invariance across time and gender. These findings further establish the psychometric defensibility of the SRSS as used within multitiered systems of support. Implications, limitations, and future directions are discussed for practitioners and researchers. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Background: Adaptive skills measures tend to be lengthy. The GO4KIDDS (Great Outcomes for Kids Impacted by Severe Developmental Disabilities; (Journal of Applied Research in Intellectual Disabilities, 58, 2015 and 594)) Brief Adaptive Behaviour Scale was developed to provide a brief assessment of adaptive skills. Our study aimed to examine the psychometric properties of G04KIDDS Brief Adaptive Scale in a large sample of children in special education., Methods: Teachers reported on 361 students with severe to profound intellectual disability. The scale's factor structure was examined through principal components analysis (PCA), while its convergent validity was examined in relation to the Vineland (VABS-II; Vineland-II adaptive behavior scales, Circle Pines, MN, AGS and 2005)., Results: The PCA indicated a single component measuring overall adaptive skills, which had excellent internal consistency (alpha = 0.93), and convergent validity (Pearson's r = 0.81)., Conclusions: Teacher-reported scores on GO4KIDDS Brief Behaviour Scale can provide a reliable and valid composite of adaptive skills in children with severe to profound intellectual disability. The scale will be useful to researchers and teachers who need a brief descriptive assessment of adaptive functioning., (© 2018 John Wiley & Sons Ltd.)

Chronic pain is a prevalent and costly condition, with many patients receiving income support and funded treatment. Given that pain cannot be assessed objectively, patients may be suspected of exaggerating their pain and disability to receive additional funding. Although numerous methods of detecting malingering have been suggested, it is unclear whether clinicians can reliably identify malingering in patients with chronic pain. The present focus article was developed to assess the theoretical basis and empirical support for proposed methods of detecting malingering in patients with chronic pain. Five approaches were identified: the evaluation of behavioral signs, effort testing, pen and paper measures, symptom validity tests, and combined methods. An examination of the literature revealed that proposed assessment tools have little theoretical basis or empirical support in patients with chronic pain. Additionally, assessment tools are inconsistent with advances in pain science and scores or observations are likely to be influenced by the typical features of chronic pain, including fear-avoidance and central sensitization. Clinicians should be aware that as yet neither subjective clinical opinions nor clinical detection methods can reliably identify malingering in patients with chronic pain. Perspective: There is interest in the development of assessment tools to detect malingering in patients with chronic pain. An evaluation of methods reveals theoretical and empirical limitations that undermine the usefulness of these approaches. As yet, there is no reliable way for clinicians to identify malingering in patients with chronic pain., (Copyright © 2018 the American Pain Society. Published by Elsevier Inc. All rights reserved.)
