Comparison to DSM-IV/DSM-IV-TR Criteria Flashcards
- No diagnostic subcategories
Encompasses Aspergers and PDD-NOS but not Rett’s or Childhood Disintegrative Disorder. Reflect evidence that subcategories are not valid or reliable.
Evidence for removal of subcategories: Lack of consistency in differences between subcategories
Manivijiona & Prior (1995)
Evidence for removal of subcategories: Can’t identify them reliably
Happe (2011)
- Social communication + social interaction
Recognise that social interaction is involved in social communication, can’t be separated
Evidence for merging communication and interaction (Factor analysis better fit)
Frazier et al (2012) factor analysis, better fit
- More stringent criteria (how?)
DSM-IV 6 overall (2A 1B 1C)
Evidence for more stringent criteria (Combat early overdiagnosis, only 63% diagnosed at 2 showed symptoms at 4)
Turner & Stone (2007)
Evidence against more stringent criteria (early intervention can improve development/milestones even if child does not have ASD)
Silverstein (2006)
Reccomendation for less stringent criteria (2/3 and 1/4) 0.93 0.74
Barton et al (2013) sensitivity=.93 specificity=.74
- Sensory issues
Now a behavioural symptom
Evidence for inclusion of sensory issues (girls)
Lai (2011) more common in girls
Barton et al (2013) girls under-identified
- Doesn’t have to be before 3, why?
Individual differences in development (may not become fully manifest until social demands exceed limited capacities)
- Severity levels of impairment (How does this differ?)
Qualitative descriptions instead of optional use of Global Assessment of Functioning
Evidence against severity levels of impairment (overlap, intervention implications)
Weitlauf et al (2014)
Changes in sensitivity/specificity (Less Aspergers/PDD-NOS, 1/100 1/68 more females/older children?)
McPartland (2012) less
CDC (2014) increased prevalance
