The classification of mental health disorders can be valadated as well as the disadvantages of the categorization.
The separate categories are representitive of various characteristics of the disorder and etiology as well as for treatment intervention approaches/techniques and symptomology. The classifications also give insurance companies a better understanding of the diagnosis and treatments for billing and compensation purposes.
The opposite could pose true pertaining to this end of the spectrum. Insurance companies could translate the classifications as something different than intended by the therapist creating errors in billing. There could be errors in the paperwork suggestive and indictive of the wrong diagnosis/prognosis causing misconstrewed information and unnecessary concerns for the therapist, client, and third party.
Hope this helps.
Sorry this answer came too late. I had to turn it in by Saturday. Thank you for your help anyway but did not come soon enough.
