Research has indicated that males diagnosed with autism spectrum disorder (ASD) outnumber females diagnosed with ASD, which has been attributed to a number of potential biological and genetic risk factors. The purpose of this paper is to estimate how many girls may be missing from ASD via a two-study format, comparing two distinct data sets to Centers for Disease Control and Prevention population estimates for sex distribution of males vs females in ASD.

In Study 1, the authors utilized data from the National Database for Autism Research as a clinic-based sample. In Study 2, the authors utilized data from the National Survey of Children’s Health as a community-based sample.

The current study estimates that approximately 39 percent more girls should be diagnosed with ASD. The authors estimate that the sex distribution in ASD should be approximately 28 percent female and 72 percent male based upon current practices. Thus, it appears that more females are being identified as potentially having ASD but were not subsequently being diagnosed with ASD as compared to their male counterparts.

These results could suggest that a leaky pipeline in the assessment of girls with ASD may exist along one or more points in the ASD diagnostic process, with one potential point at the level of ASD-specific screening (i.e. the SCQ in Study 1) in the clinic setting and another in the community setting as a whole for universal screening (i.e. NSCH data in Study 2).

This paper aims to examine for differences in potentially productive fear versus all other fear scores comparing adolescents and young adults with intellectual disabilities versus their typically developing peers without intellectual disabilities while statistically controlling for chronological age.

The authors examined for differences in potentially productive fear scores versus all fear scores comparing adolescents and young adults with intellectual disabilities versus their typically developing peers without intellectual disabilities.

Results of the current study highlight the importance of examining and statistically acknowledging the form of the relationship between age and fear. As previous research has indicated the relationship of age with fear, this form of the relationship should be acknowledged in subsequent analyses. Results also present a conceptualization of fear with some fears being considered as potentially productive fears as it relates to independent living.

The current study presents a conceptualization of fear with some fears being considered as potentially productive fears as it relates to independent living as an outcome.

Results support that potentially productive fears can be considered fears that can be used to promote learning that leads to independent living outcomes such as safety and security.

Autism spectrum disorder (ASD) is a lifelong disorder that requires intervention and support services for a growing geriatric population. The purpose of this paper is to examine the mean age at death of individuals with ASD and subsequent comorbidity with Alzheimer’s disease, and any form of dementia, as a whole and according to sex.

Data consisted of 1,754 individuals who had an ASD listed as one of the causes of deaths from the National Vital Statistics System with data from 1999 to 2015. In the current study, the authors present contradictory results with a mean age at death for individuals with ASD was 68 years by adjusting for changing prevalence rates.

Females with ASD had a higher mean age at death than males with ASD; consistent with the trend in the sex differences in the general population. The results of the current study also indicate that individuals with ASD were, in fact, less likely than the general population to have Alzheimer’s disease or a form of dementia. However, males with ASD were significantly more likely to have acquired Alzheimer’s disease or a form of dementia as compared to females with ASD.

Guan and Li (2017) reported a mean age at death of 36 years old for individuals with ASD, which was subsequently reported in the mass media, most notably CNN. The authors contend that this study provides a more accurate estimate mean age at death.

In the current study, the purpose of this paper is to examine the self-regulation and social interaction skills of children with Autism Spectrum Disorder (ASD) as compared to children with intellectual disabilities (IDs) across time.

Drawn from the Special Education Elementary Longitudinal Study (SEELS), our sample consisted of 1,016 children diagnosed with ASD and 597 children diagnosed with ID. The self-regulation and social interaction skills were measured using relevant subscales of the Scales of Independent Behavior-Revised across three time points evenly spaced at two years apart.

Results revealed that children with ASD have significantly worse self-regulation (p<0.01, η2=0.12, Cohen's f=0.36) and social interaction skills (p<0.01, η2=0.05, Cohen's f=0.21) as compared to children with ID across time. The results of the current study support the results of Bieberich and Morgan (2004) that children with ASD have significantly worse self-regulation and social interaction skills as compared to children with ID across time.

The paper suggests that our results may be considered as more generalizable given the utilization of data from the SEELS as a large, nationally representative, and community-based sample of children with disabilities across the USA examined longitudinally.
