Changes from the DSM-IV to DSM-V:

• the term 'pervasive developmental disorders' was replaced by 'neurodevelopmental disorders' and subsumed under ASD
• autism was renamed as autism spectrum disorder
• merging of social and communication symptoms of autism into one domain -including abnormalities in sensory processing under restricted behaviors -changing the onset age criteria

These changes were supposedly created to ensure that autism was known as multi-dimensional, and would give clinicians a better understanding of cultural and gender-related factors.

Huerta et.al,: -DSM-V is no better than DSM-IV at diagnosing women with autism -looked at clinical records to see how sensitive the new criteria was, and compared estimated sensitivities for both men and women

• diagnostic sensitivity for women: .88 - .93
• diagnostic sensitivity for men: .89 - .92 This does not display a significant difference between DSM-IV and DSM-V.

Kim et, al,:

• epidemiological study in South Korean community comparing male to female ratio in DSM-IV versus DSM-V
• DSM-IV: 2.5:1 (male:female)
• DSM-V: 2.7:1 (male:female)
