Introduction

The Checklist for Autism Spectrum Disorder is a screening tool to test for autism in children ages one to seventeen (Checklist for Autism Spectrum Disorder-Short form, 2017). When used for diagnosis criteria the Checklist for Autism Spectrum Disorder must be completed by a qualified technician; however, it can be used for research purposes and be completed by a parent (Checklist for Autism Spectrum Disorder, 2017). The publisher notes the Checklist for Autism Spectrum Disorder has the ability to differentiate between those with Autism Spectrum Disorder and ADHD, with one hundred percent accuracy. It is also noted the Checklist for Autism Spectrum Disorder has tremendous agreement with the Autism Diagnostic Interview-Revised and the Childhood Autism Rating Scale (Checklist for Autism Spectrum Disorder-Short form, 2017).

Technical Review

Hollway, J. & Aman, M. (2011). Sleep correlates of pervasive developmental disorders: A review of the literature. Research In Developmental Disabilities, 32(5), 1399- 1421. http://dx.doi.org/10.1016/j.ridd.2011.04.001

This test addressed reliability. The reliability coefficient when the Checklist for Autism Spectrum Disorder was completed by a qualified clinician was .33. When the Checklist for Autism Spectrum Disorder was completed by a parent the reliability coefficient was .44. This shows there is no strong correlation between sleep disorders and autism when the test is completed by both a qualified clinician and a parent. The type of reliability being tested was internal consistency. The source of error variance could be contributed to test construction.

Mayes, S., Black, A., & Tierney, C. (2013). DSM-5 under-identifies PDDNOS: Diagnostic agreement between the DSM-5, DSM-IV, and Checklist for Autism Spectrum Disorder. Research In Autism Spectrum Disorders, 7(2), 298-306. http://dx.doi.org/10.1016/j.rasd.2012.08.011

This test addressed reliability and validity. There were several factors involved in this test. The reliability coefficient when addressing the DSM-V, DSM-IV, and Checklist for Autism Spectrum Disorder was 1. All three of these tests were in agreement in the diagnosis of autism spectrum disorder for high functioning autism and low functioning autism. The type of reliability was internal consistency and the source of error variance could be contributed to test construction. When using the DSM-V, DSM-IV, and Checklist for Autism Spectrum Disorder to test for pervasive developmental disorder-not otherwise specified, the reliability coefficient was .2. This type of reliability was also internal consistency and the source of error variance could be contributed to test construction. The type of validity being measured was convergent validity. The authors wanted to know how well the Checklist for Autism Spectrum Disorder complied with the DSM-V and the DSM-IV when testing for autism and pervasive developmental disorder-not otherwise specified.

This test addressed reliability. While the authors do not provide a reliability coefficient, they do state there is a high agreement between maternal anxiety/depression and adolescents diagnosed with autism. The agreement is more profound in the high functioning autism range as well as those who were older in age. The type of reliability being addressed is inter-scorer and the source of error variance could be contributed to scoring and interpretation.

Comparison of Scores on the Checklist for Autism Spectrum Disorder, Childhood Autism Rating Scale, and Gilliam Asperger’s Disorder Scale for Children with Low Functioning Autism, High Functioning Autism, Asperger’s Disorder, ADHD, and Typical Development. Journal Of Autism And Developmental Disorders, 39(12), 1682-1693. http://dx.doi.org/10.1007/s10803-009-0812-6 This test addressed reliability and validity. The reliability coefficient between the Childhood Autism Rating Scale and the Checklist for Autism Spectrum Disorder was .98 for parent agreement. The reliability coefficient between the Checklist for Autism Spectrum Disorder and the Gilliam Asperger’s Disorder Scale was .94 for parent agreement. When it came to clinician scores the reliability coefficient for the Childhood Autism Rating Scale and the Checklist for Autism Spectrum Disorder was .82. The clinician reliability coefficient for the Checklist for Autism Spectrum Disorder and the Gilliam Apserger’s Disorder Scale was .81. The type of reliability being tested was internal consistency and the source of error variance could be contributed to test construct. The type of validity being measured is concurrent validity. Each test was being utilized to determine if they all met a certain criteria to diagnose autism spectrum disorder.

Final DSM-5 under-identifies mild Autism Spectrum Disorder: Agreement between the DSM-5, CARS, CASD, and clinical diagnoses. Research In Autism Spectrum Disorders, 8(2), 68-73. http://dx.doi.org/10.1016/j.rasd.2013.11.002

This test addressed reliability and validity. The reliability coefficient between the Childhood Autism Rating Scale and the Checklist for Autism Spectrum Disorder was .94; however, when these two tests were compared against the DSM-V their reliability coefficient was .84 for the Childhood Autism Rating Scale and .88 for the Checklist for Autism Spectrum Disorder. The type of reliability was alternate- form and the source of error variance could be contributed to test construction or administration. The type of validity being measured was concurrent. The DSM-V has a specific criterion that must be met; the Childhood Autism Rating Scale and the Checklist for Autism Spectrum Disorder must comply with these criteria in order to offer a conclusive diagnosis.

Journal Of Autism And Developmental Disorders, 41(11), 1586-1590. http://dx.doi.org/10.1007/s10803-011-1178-0

This test addressed reliability. The reliability coefficient between the Autism Diagnostic Interview-Revised and the Checklist for Autism Spectrum Disorder was .93. The type of reliability being assessed was alternate-form and the source of error variance could be contributed to test construction or administration.

This test addressed reliability. The reliability coefficient when comparing the Social Communicative Questionnaire and the Checklist for Autism Spectrum Disorder was .82. The type of reliability addressed was alternate form and the source of error variance could be contributed to test construction or administration.

Conclusion

In regards to reliability, the reliability was quite high (1) when testing for autism with the DSM-V, DSM-IV, and the Checklist for Autism Spectrum Disorder. When the DSM-V, DSM-IV, and the Checklist for Autism Spectrum Disorder were used to test for pervasive developmental disorder-not otherwise specified the reliability dropped to .2 (Mayes, Black, & Tierney, 2013). In a later study the DSM-V is compared to the Checklist for Autism Spectrum Disorder and the reliability coefficient is .88 (Mayes et al., 2014). One can infer from these coefficients the Checklist for Autism Spectrum Disorder can conclusively diagnose a person with autism spectrum disorder. When compared to other autism diagnosis tests the Checklist for Autism Spectrum Disorder received a reliability coefficient of .82 against the Childhood Autism Rating Scale (Mayes et al., 2009), a .81 against the Gilliam Asperger’s Disorder Scale (Mayes et al., 2009), and a .93 against the Autism Diagnostic Interview-Revised (Murray, Mayes, & Smith, 2011). This shows the Checklist for Autism Spectrum Disorder and these other tests are as dependable when testing for autism. The Checklist for Autism Spectrum Disorder had a low reliability coefficient when it came to sleep disorders (Hollway & Aman, 2011). This would infer the Checklist for Autism Spectrum Disorder was not effective when testing for sleep disorders in children with autism.

The Checklist for Autism Spectrum Disorder deemed to be accurate according to the DSM-V standards when testing for autism spectrum disorder (Mayes, Black, & Tierney, 2013). Concurrent validity is shown between the DSM-V and the Checklist for Autism Spectrum Disorder (Mayes et al., 2014), as well as between the Checklist for Autism Spectrum Disorder, Childhood Autism Rating Scale, and Gilliam Asperger’s Disorder Scale (Mayes et al., 2009).

Based on my findings I can evaluate the Checklist for Autism Spectrum Disorder is effective in testing for autism spectrum disorder. It has been proven to be an effective method amongst more expensive tests and is conclusive with the DSM-IV and DSM-V. Although it is not an effective test for all measures, such as determining a correlation between sleep disorders and autism (Hollway & Aman, 2011), it can provide a clear diagnosis of autism spectrum disorder.
