Sixty-four (59 %) of the 108 originally 'Diagnosed Not Autistic' met the current ASD case definition. The average IQ estimate in the newly identified group (IQ = 35.58; SD = 23.01) was significantly lower than in the original group (IQ = 56.19 SD = 21.21; t = 5.75; p .0001). Today's diagnostic criteria applied to participants ascertained in the 1980s identified more cases of autism with intellectual disability. The current analysis puts this historic work into context and highlights differences in ascertainment between epidemiological studies performed decades ago and those of today.

Excess Mortality and Causes of Death in Autism Spectrum Disorders: A Follow up of the 1980s Utah/UCLA Autism Epidemiologic Study / Deborah A. BILDER in Journal of Autism and Developmental Disorders, 43-5 (May 2013)

Twenty-nine of these individuals (9.5 %) died by the time of follow up, representing a hazard rate ratio of 9.9 (95 % CI 5.7–17.2) in relation to population controls. Death certificates identified respiratory, cardiac, and epileptic events as the most common causes of death. The elevated mortality risk associated with ASD in the study cohort appeared related to the presence of comorbid medical conditions and intellectual disability rather than ASD itself suggesting the importance of coordinated medical care for this high risk sub-population of individuals with ASD.

A Scale to Assist the Diagnosis of Autism and Asperger’s Disorder in Adults (RAADS): A Pilot Study / Riva-Ariella RITVO in Journal of Autism and Developmental Disorders, 38-2 (February 2008)

It was standardized on 17 autistic and 20 Asperger’s Disorder and 57 comparison subjects. Both autistic and Asperger’s groups scored significantly higher than comparison groups with no overlap; sensitivity, specificity, and content validity equaled one. Cronbach’s alpha coefficients of internal consistency of three subscales were satisfactory. Gender, age, and diagnostic categories were not significantly associated factors. The RAADS can be administered and scored in less than an hour and may be useful as a clinical scale to assist identification of autism and Asperger’s Disorder in adults. The RAADS does not distinguish between autism and Asperger’s Disorder.

The FIPS-A is based on register linkages between births from 1987 to 2005 ascertained from the Finnish Medical Birth Register (FMBR) and other national registers on treatment for this group of disorders. All subjects were members of the Finnish Maternity Cohort (FMC), which consists of virtually all births in Finland from 1983 to the present, and which includes archived maternal serum samples. This study also capitalizes on other registry information, such as systematically collected data on pregnancy, prenatal and neonatal complications and manual data collection from well-child clinics providing developmental data from birth to the age of 7 years. In this paper, we describe the methods used in the FIPS-A study, including a description of the national registers, available data and case ascertainment procedures. Finally, we discuss implications of the data for future work on uncovering putative aetiologies of ASD and key strengths and limitations of the design.

This study evaluates the psychometric properties of the Swedish version of the Ritvo Autism and Asperger Diagnostic Scale-Revised (RAADS-R), an 80-item self-rating scale designed to assist clinicians diagnosing ASD in adults. It was administered to 75 adults with ASD and 197 comparison cases. Also, a subset completed the Autism Spectrum Quotient (AQ). Three out of four subscales had high internal consistency. Sensitivity was 91% and specificity was 93%. The ASD subjects had significantly higher mean scores on all subscales. ASD females had higher scores than ASD males on the sensory motor subscale, a dimension not included in the AQ. RAADS-R showed promising test re-test reliability.
