The DSM is the Diagnostic and Statistical Manual of Mental Disorders. This is used to help clinicians and other health care professionals with their line of work and diagnosis. In 2013 the DSM-IV has changed over to the DSM-5. With this there have been changes in the groupings of disorders, new disorders added, and some completely different. With these changes has come a lot controversy. An area that has seen drastic changes is within the Pervasive Developmental Disorders. Within the DSM-IV under Pervasive Developmental Disorders was Autistic Disorder, Asperger’s Disorder and Childhood Degenerative Disorder. These disorders are now all grouped into Autism Spectrum Disorder in the DSM-5. Thus, posing the question as to if these changes were

Sensitivity refers to finding out how many people test correctly for the specific disorder or disease. Where specificity refers to finding out how many people do not have the specific disorder to disease. In the case of changing from the DSM-IV to the DSM-5; there was an underlying fear of lacking in the area of sensitivity as it pertains to clinical testing. Unfortunately there has been a decrease in sensitivity, however there has been a great increase in specificity. This shows to be beneficial. There was a study presented within 2012 before the DSM-5 came out in which defends this statement. “Huerta and colleagues reported on data from 4,453 children aged 2-17 with DSM-IV-TR diagnoses of PDD and 690 children with non-PDD diagnoses. They report that the new DSM-5 criteria identified 91% of the children with DSM-IV-TR diagnoses of PDD with specificity estimated at .53. In addition, they report adequate sensitivity for children diagnosed with PDD-NOS and Asperger's Disorder, and for girls and children with nonverbal IQs below 70”. (Barton, Robins, Jashar, Brennan & Fein, 2013).Furthermore, “The authors also calculated sensitivity and specificity using one symptom reported by parents, one observed by clinicians, and a requirement that symptoms be both reported and observed; they noted that while sensitivity decreased slightly, specificity improved to .63 when both observation and parental report were required”(Barton, Robins, Jashar, Brennan & Fein, 2013).Specificity is extremely important due to the fact, for those who do not have the disorder being studied, they can then be considered for other disorders and this will help with things like
