Autism Diagnostic Interview-Revised
The Autism Diagnostic Interview-Revised (ADI-R) is a structured interview conducted with the parents of individuals who have been referred for the evaluation of possible autism or autism spectrum disorders. The interview, used by researchers and clinicians for decades, can be used for diagnostic purposes for anyone with a mental age of at least 24 months and measures behavior in the areas of reciprocal social interaction, communication and language, and patterns of behavior.Le Couteur, A., Lord, C., & Rutter, M. (2003). Autism Diagnostic Interview-Revised (ADI-R). Retrieved Mar. 5, 2009, from Autism Genetic Resource Exchange, Los Angeles, CA. Web site: http://www.agre.org/program/aboutadi.cfm. Structure Useful for diagnosing autism, planning treatment, and distinguishing autism from other developmental disorders. The interview covers the referred individual's full developmental history, is usually conducted in an office, home or other quiet setting by a psychologist, and generally t ...

Interview
An interview is a structured conversation where one participant asks questions, and the other provides answers.Merriam Webster DictionaryInterview Dictionary definition, Retrieved February 16, 2016 In common parlance, the word "interview" refers to a one-on-one conversation between an ''interviewer'' and an ''interviewee''. The interviewer asks questions to which the interviewee responds, usually providing information. That information may be used or provided to other audiences immediately or later. This feature is common to many types of interviews – a job interview or interview with a witness to an event may have no other audience present at the time, but the answers will be later provided to others in the employment or investigative process. An interview may also transfer information in both directions. Interviews usually take place face-to-face and in person but the parties may instead be separated geographically, as in videoconferencing or telephone interviews. I ...

Test-retest Reliability
Repeatability or test–retest reliability is the closeness of the agreement between the results of successive measurements of the same measure, when carried out under the same conditions of measurement. In other words, the measurements are taken by a single person or instrument on the same item, under the same conditions, and in a short period of time. A less-than-perfect test–retest reliability causes test–retest variability. Such variability can be caused by, for example, intra-individual variability and inter-observer variability. A measurement may be said to be ''repeatable'' when this variation is smaller than a pre-determined acceptance criterion. Test–retest variability is practically used, for example, in medical monitoring of conditions. In these situations, there is often a predetermined "critical difference", and for differences in monitored values that are smaller than this critical difference, the possibility of variability as a sole cause of the difference ma ...

Epidemiology Of Autism
The epidemiology of autism is the study of the incidence and distribution of autism spectrum disorders (ASD). A 2022 systematic review of global prevalence of autism spectrum disorders found a median prevalence of 1% in children in studies published from 2012 to 2021, with a trend of increasing prevalence over time. However, the study’s 1% figure may reflect an underestimate of prevalence in low- and middle-income countries. ASD averages a 4.3:1 male-to-female ratio in diagnosis, not accounting for ASD in gender diverse populations, which overlap disproportionately with ASD populations. The number of children known to have autism has increased dramatically since the 1980s, at least partly due to changes in diagnostic practice; it is unclear whether prevalence has actually increased; and as-yet-unidentified environmental risk factors cannot be ruled out. In 2020, the Centers for Disease Control's Autism and Developmental Disabilities Monitoring (ADDM) Network reported that approx ...

Autism Speaks
Autism Speaks Inc. is a controversial autism advocacy organization and the largest autism research organization in the United States. It sponsors autism research and conducts awareness and outreach activities aimed at families, governments, and the public. It was founded in February 2005 by Bob Wright and his wife Suzanne, a year after their grandson Christian was diagnosed with autism. The same year as its founding, the organization merged with Autism Coalition for Research and Education. It then merged with the National Alliance for Autism Research in 2006 and Cure Autism Now in 2007. The autism rights movement and neurodiversity advocates see autism as a difference rather than a disease that needs to be cured, and have criticized Autism Speaks for seeking a cure. However, the word "cure" was dropped from its mission statement in 2016. History Autism Speaks was founded in February 2005 by Bob Wright, vice chairman of General Electric, and his wife Suzanne, a year after ...

Autism Society Of America
The Autism Society of America (ASA) was founded in 1965 by Bernard Rimland and Ivar Lovaas together with Ruth C. Sullivan and a small group of other parents of children with autism. Its original name was the National Society for Autistic Children; the name was changed to emphasize that autistic children grow up. The ASA's stated goal is to increase public awareness about autism and the day-to-day issues faced by autistic people as well as their families and the professionals with whom they interact. Although the group has promoted the pseudoscientific belief that vaccines cause autism in the past, it now affirms that there is no link between vaccination and autism. In 2021, the ASA launched a new brand including a logo consisting of multicolor lines forming a fabric with a new slogan, "The Connection Is You". Founders Ivar Løvaas Ole Ivar Løvaas (8 May 1927 – 2 August 2010) was a Norwegian-American clinical psychologist and professor at the University of California, Los ...

Autism Diagnostic Observation Schedule
The Autism Diagnostic Observation Schedule (ADOS) is a standardized diagnostic test for diagnosing and assessing autism, now in its second edition as of 2012. It is considered to be a "''gold standard''" in diagnosing Autism Spectrum Disorder (ASD). The protocol consists of a series of structured and semi-structured tasks, that involve social interaction between the examiner and the person under assessment. The examiner observes and identifies segments of the subject's behavior, and assigns these to predetermined observational categories. Categorized observations are subsequently combined to produce quantitative scores for analysis. Research-determined cut-offs identify the potential diagnosis of autism spectrum disorder, allowing a standardized assessment of autistic symptoms. The Autism Diagnostic Interview-Revised (ADI-R), a companion instrument, is a structured interview conducted with the parents of the referred individual, and covers the subject's full developmental history. ...

Psychometric
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally refers to specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of Latent variable, latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, Mental disorder, mental disorders, and Educational measurement, educational achievement. The levels of individuals on nonobservable latent variables are Statistical inference, inferred through mathematical model, mathematical modeling based on what is observed from individuals' responses to items on tests and scales. Practitioners are described as psychometricians, although not all who engage in psychometric research go by this title. Psychometricians usually possess specific qualifications such as degrees or certifications, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Validity
Internal validity is the extent to which a piece of evidence supports a claim about cause and effect, within the context of a particular study. It is one of the most important properties of scientific studies and is an important concept in reasoning about evidence more generally. Internal validity is determined by how well a study can rule out alternative explanations for its findings (usually, sources of systematic error or 'bias'). It contrasts with external validity, the extent to which results can justify conclusions about other contexts (that is, the extent to which results can be generalized). Details Inferences are said to possess internal validity if a causal relationship between two variables is properly demonstrated.Shadish, W., Cook, T., and Campbell, D. (2002). Experimental and Quasi-Experimental Designs for Generilized Causal Inference Boston:Houghton Mifflin. A valid causal inference may be made when three criteria are satisfied: # the "cause" precedes the "eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inter-rater Reliability
In statistics, inter-rater reliability (also called by various similar names, such as inter-rater agreement, inter-rater concordance, inter-observer reliability, inter-coder reliability, and so on) is the degree of agreement among independent observers who rate, code, or assess the same phenomenon. Assessment tools that rely on ratings must exhibit good inter-rater reliability, otherwise they are not valid tests. There are a number of statistics that can be used to determine inter-rater reliability. Different statistics are appropriate for different types of measurement. Some options are joint-probability of agreement, such as Cohen's kappa, Scott's pi and Fleiss' kappa; or inter-rater correlation, concordance correlation coefficient, intra-class correlation, and Krippendorff's alpha. Concept There are several operational definitions of "inter-rater reliability," reflecting different viewpoints about what is a reliable agreement between raters. There are three operational defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autism
The autism spectrum, often referred to as just autism or in the context of a professional diagnosis autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental condition (or conditions) characterized by difficulties in social interaction, verbal and nonverbal communication, and the presence of repetitive behavior and restricted interests. Other common signs include unusual responses to sensory stimuli. Autism is generally understood as a ''spectrum disorder'', which means that it can manifest differently in each person: any given autistic individual is likely to show some, but not all, of the characteristics associated with it, and the person may exhibit them to varying degrees. Some autistic people remain nonspeaking over the course of their lifespan, while others have relatively unimpaired spoken language. There is large variation in the level of support people require, and the same person may present differently at varying times. Historically ...
