Combining disorders

Need help with my Psychology question – I’m studying for my class.

 

DQ 1

The DSM is organized by combining disorders of the same category. What are the symptomatic similarities that necessitate the clustering of these disorders? Select one class of disorders (depressive, anxiety, dissociative, etc.) and discuss.

DQ 2

As a diagnostic tool, the DSM includes diagnostic criteria for mental disorders. In addition, it includes information such as prevalence, risks, prognoses, gender-related issues, and cultural considerations for these disorders. What role might this information play in diagnosis and treatment?
