Introductory Concepts Flashcards
Focal delay
Delay in one area
Global delay
Delay in all areas
Divergent/atypical delay
Development that is unusual in pattern
Groups more likely to report developmental disability diagnosis
Boys
White and black children
Children in rural areas
Children with public insurance
Norm-referenced assessments
Compares performance to normative sample
Ex. PDMS-2, BOT-2
Criterion-referenced assessments
Compares performance to defined list of skills
May or not be standardized
Detailed, specific objectives or developmental mile stones
Ex. Pediatric development Inventory, Hawaii Early Learning Profile
What does it mean if a child scores in the 10th percentile
10% of children scored lower than the tested child
Age equivalent
Age at which most individuals reach the same level as the individual tested
Least psychometrically sound measure
Inter-rater reliability
Two practitioners who administer and score the same assessment will yield similar results
What does a confidence interval of 95% mean?
If confidence interval is 95%, this means that if I administer this test 100 times, I would get the same score 95 out of 100 times
Construct-related validity
How well the assessment is able to discriminate among different groups of individuals
Content-related validity
How well test items in an assessment represent a sample of skill for the test’s domain
Criterion related validity
How well one measure predicts an outcome for another measure test
Concurrent validity
How well a test compares to a well-established test
Rasch model of measurement
Hiearachy ranking of the test items from easiest to hardest
Typically observation or interview
