“…Comparing data across several countries for the Quantitative Checklist for Autism in Toddlers (Q-CHAT; Allison et al, 2008), it was observed that items reporting imperative and declarative pointing, as in this study, besides gestures and staring at nothing, were common for toddlers with ASD across different language/cultural groups (Stevanović, 2021).…”

“…In addition, considering the deviations of the factor loadings, there might be true variability in assessing ASD symptoms with the CARS among professionals across nations, reflecting differences in the ASD conceptualization, which may be attributable to factors such as cultural rules, practices, language, and other systems within the cultural formulation of ASD (APA, 2013; de Leeuw et al, 2020). Similar to other tools of psychopathology including ASD (e.g., Stevanović, 2021; Stevanovic et al, 2015), the CARS items may be differently sensitive to one culture than another in measuring ASD constructs or that they are easily confounded by the culture‐specific attributes related to the construct. Thus, the items might not represent specific symptoms the same way and at the same severity level or there might be some items deemed less clinically meaningful in the context of culture‐specific and reference norms (e.g., Heine et al, 2002).…”

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

“…Optimal cut-off points were selected based on their utility for screening purposes, following the proposal of Stevanovic et al. ( 29 , 36 ): sensitivity and specificity > 0.8, sensitivity ≥ specificity, and Youden´s index ≥ 0.70.…”

“…The Quantitative CHecklist for Autism in Toddlers, Q-CHAT (Allison et al., 2008) is an autism screening tool that conceptualizes the autism spectrum on a continuous scale, taking a dimensional approach to the identification of autistic traits ( 26 – 29 ). From a theoretical point of view, this proposal is consistent with the conceptual evolution of autism and with the quantitative nature of autistic traits as a continuum of symptoms and traits within the autism spectrum ( 30 ).…”

BackgroundThe aim of this study was to examine some psychometric characteristics of the Chilean-adapted version of the Quantitative Checklist for Autism in Toddlers (Q-CHAT-24) (24) in a group of unselected children (community sample). This version was administered remotely through an online version during the pandemic period to caregivers of children, aged 18–24 months, registered in four primary care polyclinics of the Health Service Araucanía Sur, Chile.MethodsAn intentional non-probabilistic sampling was used. Three hundred and thirteen toddlers were examined. Participants completed an online version of the Q-CHAT-24 which was disseminated through the REDCap platform. Evidence of reliability through internal consistency and evidence of predictive validity through ROC curve analysis were realized.ResultsThe mean age of the children evaluated was 21.16 months. The Shapiro-Wilk test revealed that Q-CHAT-24 scores was normally distributed. 71 cases (23.12%) scored 38 points or more on the Q-CHAT-24, qualifying as Autistic Risk. 48 cases (15.63%) were confirmed as autistic through the ADOS-2 Module T. All items were positively correlated with Q-CHAT-24 total score. All items were positively correlated with Q-CHAT-24 total score. Internal consistency was acceptable for the Q-CHAT-24 (Cronbach ́s α=0.78). The internal consistencies were analyzed for the Q-CHAT-24 Factors, and they were good for factor 1 “Communication and Social Interaction” (Cronbach ́s α=0.85) and acceptable for factor 2 “Restrictive and Repetitive Patterns” (Cronbach ́s α=0.74). Receiver operating characteristic (ROC) curve analyses were performed. The AUC values were 0.93 with statistical significance (p<0.01). For the cut-off point of 38, the Sensitivity, Specificity and Youden index values were 0.89, 0.8 and 0.7, respectively. The Positive Predictive Value (PPV) was 86% and the Negative Predictive Value (NPV) was 85%.ConclusionsIn accordance with the objectives of this study, evidence of reliability and predictive validity was demonstrated for the Q-CHAT-24 in this Chilean population. More importantly, this study provides Sensitivity and Specificity data for a remote application version of an autism screening tool already validated in Chile. The implications of this have to do with the possibility of establishing a remote assessment system for children at risk of autism on a population scale.
