“…This grouping of items is based on the clustering of items established by the official ADI-R scoring protocol (Lord et al, 1994), our prior work using this instrument (Seltzer et al, 2003), and recent analysis of the factor structure of the instrument (Lecavalier et al, 2006). The 33rd item was used to determine overall level of language status, which is an independent variable in the analysis described below.…”

This study examined change prospectively in autism symptoms and maladaptive behaviors during a 4.5 year period in 241 adolescents and adults with an autism spectrum disorder who were 10-52 years old (mean = 22.0) when the study began. Although many individuals' symptoms remained stable, a greater proportion of the sample experienced declines than increases in their level of autism symptoms and maladaptive behaviors, and there were significant improvements in mean levels of symptoms. Individuals with mental retardation had more autism symptoms and maladaptive behaviors than those without mental retardation, and they improved less over time. Compared to adolescents, older sample members (31 and older) had fewer maladaptive behaviors and experienced more improvement in these behaviors over time.

“…Frazier et al 67 indicated that factor structures fit equally well for 2-to 6-year-olds as for those aged ≥ 7 years. Other than testing level of agreement with ADOS (see Autism Diagnostic Observation Schedule, below), only one study 64 explicitly addressed convergent/divergent validity, finding that the ADI-R Social domain correlated with all VABS (-0.41 to -0.45) except for motor skills. A strong indication of validity at the level of individual ADI-R items in distinguishing between children with ASD and those without (mostly non-referred) was provided by Tsuchiya et al 69 Criterion validity was examined in the original Lord et al 63 paper.…”

BackgroundThe needs of children with autism spectrum disorder (ASD) are complex and this is reflected in the number and diversity of outcomes assessed and measurement tools used to collect evidence about children’s progress. Relevant outcomes include improvement in core ASD impairments, such as communication, social awareness, sensory sensitivities and repetitiveness; skills such as social functioning and play; participation outcomes such as social inclusion; and parent and family impact.ObjectivesTo examine the measurement properties of tools used to measure progress and outcomes in children with ASD up to the age of 6 years. To identify outcome areas regarded as important by people with ASD and parents.MethodsThe MeASURe (Measurement in Autism Spectrum disorder Under Review) research collaboration included ASD experts and review methodologists. We undertook systematic review of tools used in ASD early intervention and observational studies from 1992 to 2013; systematic review, using the COSMIN checklist (Consensus-based Standards for the selection of health Measurement Instruments) of papers addressing the measurement properties of identified tools in children with ASD; and synthesis of evidence and gaps. The review design and process was informed throughout by consultation with stakeholders including parents, young people with ASD, clinicians and researchers.ResultsThe conceptual framework developed for the review was drawn from the International Classification of Functioning, Disability and Health, including the domains ‘Impairments’, ‘Activity Level Indicators’, ‘Participation’, and ‘Family Measures’. In review 1, 10,154 papers were sifted – 3091 by full text – and data extracted from 184; in total, 131 tools were identified, excluding observational coding, study-specific measures and those not in English. In review 2, 2665 papers were sifted and data concerning measurement properties of 57 (43%) tools were extracted from 128 papers. Evidence for the measurement properties of the reviewed tools was combined with information about their accessibility and presentation. Twelve tools were identified as having the strongest supporting evidence, the majority measuring autism characteristics and problem behaviour. The patchy evidence and limited scope of outcomes measured mean these tools do not constitute a ‘recommended battery’ for use. In particular, there is little evidence that the identified tools would be good at detecting change in intervention studies. The obvious gaps in available outcome measurement include well-being and participation outcomes for children, and family quality-of-life outcomes, domains particularly valued by our informants (young people with ASD and parents).ConclusionsThis is the first systematic review of the quality and appropriateness of tools designed to monitor progress and outcomes of young children with ASD. Although it was not possible to recommend fully robust tools at this stage, the review consolidates what is known about the field and will act as a benchmark for future developments. With input from parents and other stakeholders, recommendations are made about priority targets for research.Future workPriorities include development of a tool to measure child quality of life in ASD, and validation of a potential primary outcome tool for trials of early social communication intervention.Study registrationThis study is registered as PROSPERO CRD42012002223.FundingThe National Institute for Health Research Health Technology Assessment programme.

“…In a large-scale factor analysis of autism diagnostic criteria, echolalia did not load on the same factor as other so-called self-stimulatory, restricted, or repetitive behaviors, such as “repetitive use of objects,” “repetitive motor movements” (e.g., hand flapping or finger flicking), or “rituals.” Instead, echolalia loaded on the same factor as other communicative behaviors, including pronoun use (Lecavalier et al 2006), which is why scales of so-called restrictive or repetitive behaviors rarely, if ever, include items assaying echolalia or linguistic repetition (Aman et al 2004, Lam & Aman 2007). …”

Autism is a developmental disability characterized by atypical social interaction, interests or body movements, and communication. Our review examines the empirical status of three communication phenomena believed to be unique to autism: pronoun reversal (using the pronoun you when the pronoun I is intended, and vice versa), echolalia (repeating what someone has said), and a reduced or even reversed production-comprehension lag (a reduction or reversal of the well-established finding that speakers produce less sophisticated language than they can comprehend). Each of these three phenomena has been claimed to be unique to autism; therefore, each has been proposed to be diagnostic of autism, and each has been interpreted in autism-centric ways (psychoanalytic interpretations of pronoun reversal, behaviorist interpretations of echolalia, and clinical lore about the production-comprehension lag). However, as our review demonstrates, none of these three phenomena is in fact unique to autism; none can or should serve as diagnostic of autism, and all call into question unwarranted assumptions about autistic persons and their language development and use.
