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…

Autistic people's perceptions of their interactions with criminal justice professionals are predominantly negative; however, little is known about the state of interactions on a global scale. To further understanding, a comprehensive stakeholder questionnaire was created. Aspects of reliability and validity including evidence for test content and…

Purpose: Research documents poor outcomes for autistic adults in the domains of employment, independent living, and social relationships. Measurement and sample limitations in prior studies may have amplified past estimates of poor outcomes. The goal of the current study was to improve upon past approaches and to create and describe a measurement…

The Autism Stigma and Knowledge Questionnaire (ASK-Q) was developed and validated to assess autism knowledge across cultural contexts. Given the wide international use of the measure, the current study aimed to re-examine the measurement properties of the ASK-Q. Using a large, international database (n = 5064), psychometric analyses examined both…

The broad autism phenotype is the phenotypic expression of the primary characteristics of autism. However, currently available tests do not agree with the two-domain operationalization of broad autism phenotype or autism, and their internal structure has shown instability across applications. This study presents the Broad Autism…

People with autism spectrum disorders (ASD) face discriminatory behaviours based on their condition, a consequence of prevailing negative attitudes in society. The main goal of this study was to adapt and validate the Societal Attitudes Towards Autism scale (SATA) for the Portuguese population. Additionally, we intended to examine possible factors…

Purpose: Intentional communication acts, or purposefully directed vocalizations and gestures, are particularly difficult for infants at elevated likelihood for eventual diagnosis of autism. The ability to measure and track intentional communication in infancy thus has the potential to aid early identification and intervention efforts. This study…

ASD manifests in children throughout the ability spectrum, though screening tools may not adequately identify high-ability youth who would benefit from a comprehensive identification evaluation; thus, the impetus for developing The High Functioning ASD Screener (HFAS). Information from content area expert interviews determined the 93-item pilot…

The Social Competence Observation Scale (SCOS) is an objective observational measure developed to assess the social performance of children with autism spectrum disorder (ASD). This paper describes development of the SCOS and results of initial testing of reliability and treatment sensitivity for a sample of 12 children, ages 4-6 years, with ASD.…

Although most children with autism and other neurodevelopmental disorders live in low- and middle-income countries, assessment tools are lacking in these settings. This study aims to culturally adapt and validate two questionnaires for use in Ethiopia: the Autism Treatment Evaluation Checklist and the Pediatric Quality of Life Inventory™ Family…

Tools to measure autism knowledge are needed to assess levels of understanding within particular groups of people and to evaluate whether awareness-raising campaigns or interventions lead to improvements in understanding. Several such measures are in circulation, but, to our knowledge, there are no psychometrically-validated questionnaires that…

At present, there are no brief, freely-available, informant-report measures that evaluate key challenging behaviors relevant to youth with autism spectrum disorder (ASD) or other developmental disabilities (DD). This paper describes the development, refinement, and initial psychometric evaluation of a new 18-item measure, the Open-Source…

Background and Aims: A literature review of both Eastern and Western literature regarding families of children with autism spectrum disorder (ASD) revealed limited empirical research that examines ASD in China. Furthermore, most research in this area comes from a deficit model and there is a lack of research that comes from a strengths background.…

Existing measures of communication challenges in autism are based on diagnostic criteria and research/clinical observations of autistic people, rather than what autistic people themselves identify as difficulties. In this study, the Conversation Questionnaire (CQ) was developed based on community engagement with autistic people to identify what…

Informant-report measures for screening symptoms of autism spectrum disorder (ASD) and other neurodevelopmental disorders (NDDs) are needed for low-resource settings if early identification is to be prioritized because early developmental concerns are likely to be expressed by parents and other caregivers. This paper describes the initial…
