Studies assessing domains pertaining to structural language in autism vary in reporting practices and approaches to assessment: A systematic review.

LAY ABSTRACT: Under the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), language impairment can co-occur with autism. It is not yet clear how research defines, reports, and characterizes structural language abilities of autistic individuals eligible for school-based special education services (aged 3-21 years) in the United States. In the United States, students typically must be formally diagnosed to be eligible for services and supports. However, the quality of diagnosis is only as good as the research evidence on which diagnosis depends. To evaluate evidence quality, we examined how studies of school-aged autistic individuals report assessments of language ability. This systematic review included 57 studies using English language age-referenced assessments used to measure structural language. Findings showed many differences across studies in how language abilities were measured and reported. Also, none of the studies fully reported the variables relevant to characterizing language impairment. Outcomes were similar across versions of the Diagnostic and Statistical Manual of Mental Disorders. Findings indicate that researchers and clinicians should pay attention to reporting diagnostic and grouping criteria. Carefully interpreting research evidence is critical for ensuring that diagnostic criteria and supports are representative of and accessible to autistic individuals and relevant parties.

Studies pertaining to language impairment in school-age autistic individuals underreport participant socio-demographics: A systematic review.

LAY ABSTRACT: Although exclusion of racially and ethnically minoritized autistic individuals from research is a long-standing issue, we have yet to determine how exclusion impacts areas of autism research important for identifying language impairment. Diagnosis depends on the quality of the evidence (i.e. research) and is often the pathway to gaining access to services. As a first step, we examined how research studies related to language impairment in school-age autistic individuals report participant socio-demographics. We analyzed reports using age-referenced assessments in English (n = 60), which are commonly used by both practitioners and researchers to diagnose or identify language impairment. Findings showed only 28% of studies reported any information on race and ethnicity; in these studies, most (at least 77%) of the participants were white. In addition, only 56% of studies reported gender or sex and specified what they were reporting (gender, sex, or gender identity). Just 17% reported socio-economic status using multiple indicators. Altogether, findings indicate broad issues with underreporting and exclusion of racially and ethnically minoritized individuals, which might overlay with other aspects of identity including socio-economic status. It is impossible to determine the extent and precise nature of exclusion without intersectional reporting. To ensure that language in autism research is representative of the autistic population, future research must implement reporting guidelines and broaden inclusion of who participates in research studies.

Behavioral economic measurement of cigarette demand: A descriptive review of published approaches to the cigarette purchase task.

The cigarette purchase task (CPT) is a behavioral economic method for assessing demand for cigarettes. Growing interest in behavioral correlates of tobacco use in clinical and general populations as well as empirical efforts to inform policy has seen an increase in published articles employing the CPT. Accordingly, an examination of the published methods and procedures for obtaining these behavioral economic metrics is timely. The purpose of this investigation was to provide a review of published approaches to using the CPT. We searched specific Boolean operators (["behavioral economic" AND "purchase task"] OR ["demand" AND "cigarette"]) and identified 49 empirical articles published through the year 2018 that reported administering a CPT. Articles were coded for participant characteristics (e.g., sample size, population type, age), CPT task structure (e.g., price framing, number and sequence of prices; vignettes, contextual factors), and data analytic approach (e.g., method of generating indices of cigarette demand). Results of this review indicate no standard approach to administering the CPT and underscore the need for replicability of these behavioral economic measures for the purpose of guiding clinical and policy decisions.

Clinical preventive service use disparities among subgroups of people with disabilities: A scoping review.

BACKGROUND: Recommended use of clinical preventive services (CPS) reduces morbidity and mortality from preventable conditions. Disparities in CPS utilization between individuals with and without disabilities have been shown, but a greater understanding of the disability subpopulations with lowest utilization is needed to better inform research, policy, and practice. OBJECTIVE: The objective was to conduct a scoping review of the literature to identify relevant studies on disparities in receipt of CPS among subgroups of individuals with disabilities. METHODS: In July 2010, electronic and manual literature searches were conducted for years 2000-2009. Review for inclusion/exclusion and data analysis occurred in 2010 and 2011. In 2012, the review was updated to cover abstracts published in 2010 and 2011. Identified abstracts, and then full-text articles of included abstracts, were reviewed according to inclusion/exclusion criteria by multiple reviewers. For articles meeting all criteria, two reviewers performed independent data extraction. A gap analysis was performed to identify areas of concentration and gaps in the literature. RESULTS: Twenty-seven articles met inclusion criteria for this review. Studies varied substantially in sample composition and research methods. CPS examined most often were cervical cancer screening (14 studies) and mammography (13 studies). Potential disparity factors studied most often were disability factors (i.e., disabling condition in 12 studies, disability severity in 10 studies). Stratification of CPS by disparity factors revealed substantial gaps in the literature. CONCLUSIONS: The literature gaps point to a need for high quality research on access disparities among subgroups of individuals with disabilities.
