Vineland-3 Measurement Non-Invariance in Children With and Without Intellectual and Developmental Disabilities.

Measurement of adaptive skills is important in the diagnosis, intervention planning, and progress monitoring of children with intellectual and developmental disabilities (IDD). Thus, ensuring accurate measurement, including measurement invariance, across children with and without IDD is critical. In this study, we evaluate the measurement invariance using multigroup confirmatory factor analysis (MG-CFA) of the Vineland-3 Comprehensive Interview (CIF) across children ages 6-21 years with and without IDD (N = 1,192) using archival data. Results showed that the Vineland-3 CIF exhibits configural invariance but may show some metric non-invariance in children with and without IDD. Suggestions for using the Vineland-3 CIF in this population are provided and future research and measure development needs are discussed.

Assessment and Management of Attention-Deficit/Hyperactivity Disorder: Pediatric Resident Perspectives on Training and Practice.

Attention-deficit/hyperactivity disorder (ADHD) is a common presenting concern in primary care. This study examined the relationship between pediatric residency training program characteristics and residents' ADHD knowledge, attitudes, and comfort in providing ADHD services. Given the familiarity that pediatric chief residents have with the training and experiences within their residency programs, a 30-item survey was mailed to pediatric chief residents. A total of 100 residents returned their surveys (response rate 49.5%) and were included in the descriptive quantitative and thematic qualitative analyses. The majority of participants rated their ADHD knowledge as at least average. However, approximately half of the participants were comfortable with screening, and less than half were comfortable with managing stimulant medication or behavioral treatments. Participants emphasized the importance of interprofessional collaboration, clinical experiences, and integrated ADHD education throughout training. These results emphasize the importance of improved training in screening, diagnosing, and managing ADHD to increase resident comfort regarding these practices.

A Systematic Review of ADHD Knowledge Measures and Their Psychometric Support.

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) knowledge is associated with reduced stigma, earlier identification, and increased intervention access. Several ADHD knowledge measures have emerged. However, the psychometric quality of these measures varies wildly, and a review of the current psychometric support for ADHD knowledge measures is lacking. METHODS: The current study is a systematic review of ADHD knowledge measures for the reported psychometric support and the populations in which they are validated. The databases PsycINFO, ERIC, and PubMed were searched using PRISMA guidelines for peer-reviewed publications using a direct ADHD knowledge measure for original data collection. An ancestral search and the inclusion of dissertations were used to reduce potential publication bias. Included articles were coded for psychometric support, population of interest, and validation sample characteristics. RESULTS: A total of 163 articles were identified, including a total of 96 ADHD knowledge measures. The majority of measures (71.8%) did not include adequate psychometric evidence to constitute an evidence-based measure. Within that, approximately a third of ADHD knowledge measures were not accompanied by any psychometric support. Many measures are designed for and validated in only one population. Most studies did not report racial and ethnic validation sample composition; among those that did, there is a lack of diversity. CONCLUSIONS: The lack of psychometric evidence for ADHD knowledge measures calls into question the current literature regarding ADHD knowledge, particularly related to racially and ethnically minoritized respondents with whom few measures have been validated. Implications for researchers and clinicians selecting an ADHD knowledge measure are discussed.

Caregiver Perceptions of Social Communication and Interaction: Development and Validation of the SCIPS.

Social communication and interaction (SC/I) skill quality may be influenced by cultural values, norms, and expectations. Because difficulties in SC/I is a core criterion for identifying autism and is a frequent construct of interest in autism research, a measure designed to capture cross-cultural differences in the perspectives of SC/I skills is warranted. To address this need we developed and validated the Social Communication and Interaction Perceptions Scale (SCIPS), a caregiver report measure for children ages 6-18 years, that measures both frequency and perceived importance of various SC/I skills. Results from 401 diverse caregiver participants showed that for both domains (i.e., Frequency and Importance) the SCIPS has good reliability (α = 0.88-0.95) and two factors that examine basic and advanced aspects of SC/I skills. Findings support the use of the SCIPS as a measure of caregiver perspectives of SC/I skills in clinical and research contexts.

The Experience of ADHD as Reported by Racially and Ethnically Minoritized Adolescents: a Survey-Based Phenomenological Investigation.

The variety of possible suboptimal long-term outcomes associated with attention-deficit/hyperactivity disorder (ADHD) when left unsupported highlights the importance of timely and accurate identification followed by intervention. Though considerations of race and ethnicity are essential to service delivery, disparities in ADHD identification and intervention persist for racially and ethnically minoritized (REM) youth. This is exacerbated by a lack of research focusing on REM populations. The current study is a phenomenological investigation of REM adolescents' (N = 35) experiences with ADHD. Participant responses to an online phenomenological survey yielded four themes and eleven subthemes related to ADHD symptom experiences, navigating social relationships and school, stigma, and finding positivity in ADHD. Participant experiences corroborate and expand on extant research regarding ADHD symptoms, social isolation, school discipline referrals, and stigma. These findings highlight the importance of including REM participants in research and increased efforts to decrease stigma.

Executive functioning skills in early childhood children with autism, intellectual disability, and co-occurring autism and intellectual disability.

BACKGROUND: Many children with autism and intellectual disability (ID) experience executive functioning (EF) difficulties. However, there is minimal research on EF skills in children with autism, ID, and co-occurring autism/ID in early childhood. AIMS: To address this gap in the research, we evaluated EF profiles using the BRIEF-P among early childhood children (2-5 years of age) with autism, ID, and co-occurring autism/ID. METHOD AND PROCEDURES: Participants in the current study were 87 children between the ages of 24 and 71 months (M = 46.8, SD = 12.7) diagnosed with autism (n = 24, 27.6 %), ID (n = 23, 26.4 %), or co-occurring autism/ID (n = 40, 46.0 %) that completed a comprehensive psychological evaluation at a university development center. We used a mixed Analysis of Variance (ANOVA) and between- and within-subjects ANOVAs as follow-up analyses. OUTCOMES AND RESULTS: Results suggested that early childhood children with autism, ID, and autism/ID may have unique EF skill profiles. Children with ID exhibited the most significant EF impairments and children with autism had the least. Working memory was the most impaired EF domain across all diagnostic groups. CONCLUSIONS AND IMPLICATIONS: Overall, our findings show that early childhood children with autism, ID, and autism/ID exhibit difficulties in EF skills. Children with ID exhibit the most significant EF impairments whereas children with autism show the least. However, regardless of diagnosis, working memory is the most impaired EF skill.

Influences of student race/ethnicity and gender on autism special education classification considerations.

LAY ABSTRACT: Autism prevalence has continued to rise in recent years. However, females and children from Black, Latinx, and Asian backgrounds are often misidentified or identified less often than White males. These identification disparities make it difficult for children to receive appropriate special education and school intervention services. In this study, school psychologists read a vignette featuring a student with possible autism symptoms. The vignette varied by student race/ethnicity and gender. Afterward, participants rated the likelihood that they would classify the student with autism and their confidence in this rating. Student race/ethnicity and gender influenced both classification likelihood and confidence. These results suggest that school psychologists are influenced by implicit bias and do not fully consider cultural factors in school autism evaluations. This may contribute to identification disparities.

Brief Report: A Brief Video Intervention for Increasing Autism Knowledge in a General Population Sample.

As many individuals in the general population will likely interact with autistic persons in various contexts, ensuring adequate autism knowledge and awareness is important. Increased knowledge of autism has been linked to positive outcomes such as a reduction in explicit bias against autism by non-autistic adults and an increase in service quality for autistic individuals provided by indirect professionals. For this study we developed an informational video about autism and employed a randomized control trial to evaluate its effectiveness at increasing autism awareness in a general population sample. Participants were randomly assigned to the intervention (n = 80) or active control group (n = 72). Results from a repeated measures analysis of variance indicated that the video intervention was effective at increasing knowledge about autism. Results from this study can be applied to future educational efforts aimed at increasing awareness about autism among the general population.

Cultural differences in social communication and interaction: A gap in autism research.

Social communication and interaction deficits are a diagnostic criteria of autism and integral to practitioner and researcher conceptualization. Culture is an influential factor in expectations for, and demonstration of, social communication and interaction skills, but there is limited research published in autism journals on this topic. This paucity of autism research examining cultural factors related to social communication and interaction may contribute to known identification disparities for racial and ethnic populations minoritized by systemic factors and research bias. We call for increased commitment from researchers to recruit racially and ethnically minoritized participants, prioritize investigating cultural expectations and perceptions of social communication and interaction, and evaluate measures related to social communication for cultural and linguistic responsivity. LAY SUMMARY: A diagnosis of autism requires the presence of deficits in social communication and interaction. Examples of these behaviors and skills include holding a back-and-forth conversation, the use of nonverbal communicative behaviors (e.g., gestures), and developing and maintaining social relationships. Culture influences the expectations for, and presentation of, these behaviors. However, research on this topic is lacking. Conducting more research related to culture and social communication could help reduce the disparities in autism identification across racially and ethnically minoritized populations.

Methods for addressing publication bias in school psychology journals: A descriptive review of meta-analyses from 1980 to 2019.

Although meta-analyses are often used to inform practitioners and researchers, the resulting effect sizes can be artificially inflated due to publication bias. There are a number of methods to protect against, detect, and correct for publication bias. Currently, it is unknown to what extent scholars publishing meta-analyses within school psychology journals use these methods to address publication bias and whether more recently published meta-analyses more frequently utilize these methods. A historical review of every meta-analysis published to date within the most prominent school psychology journals (N = 10) revealed that 88 meta-analyses were published from 1980 to early 2019. Exactly half of them included grey literature, and 60% utilized methods to detect and correct for publication bias. The most common methods were visual analysis of a funnel plot, Orwin's failsafe N, Egger's regression, and the trim and fill procedure. None of these methods were used in more than 20% of the studies. About half of the studies incorporated one method, 20% incorporated two methods, 7% incorporated three methods, and none incorporated all four methods. These methods were most evident in studies published recently. Similar to other fields, the true estimates of effects from meta-analyses published in school psychology journals may not be available, and practitioners may be utilizing interventions that are, in fact, not as strong as believed. Practitioners, researchers employing meta-analysis techniques, education programs, and editors and peer reviewers in school psychology should continue to guard against publication bias using these methods.

The ASKSP Revised (ASKSP-R) as a Measure of ASD Knowledge for Professional Populations.

It is important for all professionals who work with individuals who have ASD to have sufficient knowledge of the disorder. The development of ASD knowledge may occur during preservice training and/or through professional development. Currently, there is no "gold standard" measure of ASD knowledge. A study focusing on the development of a reliable and valid measure of ASD knowledge for practitioners and preservice professionals is warranted. To address this need, the current study provides preliminary information on the development and preliminary validation of the Autism Spectrum Knowledge Scale Professional Version-Revised (ASKSP-R) with a sample of school-based professionals (N = 427). Results suggest the ASKSP-R is a univariate measure with good reliability. Implications and suggestions for future research are discussed.

Brief Report: Development and Validation of the Autism Spectrum Knowledge Scale General Population Version: Preliminary Analyses.

Despite the dramatic rise in Autism Spectrum Disorder (ASD) prevalence, limited information is known about ASD knowledge of the general population. The Autism Spectrum Knowledge Scale, General Population version (ASKSG) was collaboratively constructed to create a measure of ASD knowledge specifically for the general population. The ASKSG is a 31-item measure that assesses one's knowledge and understanding of ASD. Adults in the general population participated in the current study (N = 318). Findings indicate that the ASKSG is a valid and reliable measure and can adequately measure ASD knowledge in this population. A greater understanding of general population knowledge pertaining to ASD can be used to better inform identification, intervention, and advocacy, thus improving the outcomes for individuals with ASD.
