We carried out a psychometric assessment of the Social Communication Questionnaire (SCQ) and the Social Responsiveness Scale (SRS-2) in fragile X syndrome (FXS), relative to clinician DSM5-based diagnosis of autism spectrum disorder (ASD) in FXS. This was followed by instrument revisions that included: removal of non-discriminating and/or low face…

Background: Community-based participatory research (CBPR) is increasingly used by community and academic partners to examine health inequities and promote health equity in communities. Despite increasing numbers of CBPR partnerships, there is a lack of consensus in the field regarding what defines partnership success and how to measure factors…

For many of my students, Real Analysis I is the first, and only, analysis course they will ever take, and these students tend to be overwhelmed by epsilon-delta proofs. To help them I reordered Real Analysis I to start with an "Analysis Boot Camp" in the first 2 weeks of class, which focuses on working with inequalities, absolute value,…

Recommendations from multiple professional organizations (e.g., American Psychological Association, Council for Exceptional Children, National Association of School Psychologists) suggest that collection of data on the social validity in practice and research is necessary. The purpose of this study was to systematically review the inclusion of…

To identify valid measures of vocal development in young children with autism spectrum disorder in the early stages of language learning, we evaluated the convergent validity, divergent validity, and sensitivity to change (across 12 months) of two measures of vocal communication and two measures of vocal complexity through conventional coding of…

Investigated internal consistency reliability and criterion validity of the Asperger Syndrome Diagnostic Scale (ASDS) in a well-characterized sample of 120 children ([X-bar][subscript age] = 9.91; autism [AUT] n = 54; non-autism [NOT] n = 66) who completed comprehensive outpatient evaluations with a gold-standard measure, the Autism Diagnostic…

There is a need for increased understanding of self-report measures for autistic individuals. In this preliminary study, we examine how a theory of mind self-report relates to other self-report measures for groups of autistic and neurotypical individuals, as well as eye tracking outcomes. Expected patterns of relatedness emerged between…

Four experiments examined the claims that people can intuitively assess the logical validity of arguments, and that qualitatively different reasoning processes drive intuitive and explicit validity assessments. In each study participants evaluated arguments varying in validity and believability using either deductive criteria (logic task) or via…

In this study, researchers compared the concordance of teacher-level effectiveness ratings derived via six common generalized value-added model (VAM) approaches including a (1) student growth percentile (SGP) model, (2) value-added linear regression model (VALRM), (3) value-added hierarchical linear model (VAHLM), (4) simple difference (gain)…

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…

The Fundamentals in Meteorology Inventory (FMI) concept inventory exam was recently developed to gauge understanding of fundamental meteorological concepts among introductory meteorology students. The exam was iteratively tested and refined over several years using a small sample of students. With a goal of evaluating the reliability and validity…

Web surveys are an established data collection mode that use written language to provide information. The written language is accompanied by visual elements, such as presentation formats and shapes. However, research has shown that visual elements influence response behavior because respondents sometimes use interpretive heuristics to make sense…

Enrollment in postsecondary institutions of higher education increased 33% between 2000 and 2014 and is projected to grow another 13% between 2014 and 2025 (Hussar & Bailey, 2017). This new wave of college students is presenting with increased mental health concerns. If left untreated, the consequences of mental health disorders, including…

Background: Organizational culture in group homes for people with intellectual disabilities has been identified as influencing staff behaviour and residents' quality of life (QOL). Despite this influence, culture has been under-researched, with no published and validated instrument to measure its dimensions in group homes. The aim was to develop…

Social media (SM) use is a rapidly growing phenomenon among Millennials. Thus, a growing body of studies have explored the beneficial applications and negative consequences of their use in an increasingly virtual world. The current study aimed to develop and validate a scale that measures university students' motives for using SM from a…
