standardized tests & assessment tools (quiz 2) Flashcards
Why do we perform these test on babies?
- determine eligibility
- compare to age matched peers
- identify delays
- establish a baseline of performance
- predict future performance
- research
norm-referenced outcome measures
- comparing child to a reference group
- ex: age matched peers
- can be used for monitoring change, however always referenced to norm group
- useful when expecting child to “catch up”
- developers seeks a large enough norming group to record the full range of performance across various demographic variables
- scores are ranked highest to lowest to determine avg performance based on the child’s age.
- used to determine difference in function compared to age matched peers
criterion -referenced outcome measures
- determining how well a child performs a specified set of knowledge, skills or abilities have changed
- less concerned about what skills are developed at a particular age, rather focus on the elements that contribute to functional mobility skills. not compared to a populations
validity properties of assessments
- ACCURATELY CAPTURING AND ASSESSING DOMAIN OF INTEREST
- consider reference group
- GMFM- 66 validated only for children with CP
- test administration - adhere to instructions
specificity
- true positive rate
- high levels of specificity indicate a positive result will rule in the condition
sensitivity
- true negative rate
- high levels of sensitive indicate that a negative result will rule out the condition or disease
predictive values (pos or neg)
- Provide an estimate of the test’s feasibility in actually identifying that a child who tests positive or negative does or does not have the dx
likelihood values (pos and neg)
- how much more like it is that the child may have a particular dx after testing positive or negative on a predictive test
Minimal detectable change
- smallest amt of change that correlates to true change that cannot be accounted for by measurement or test error
minimal clinical important difference
-smallest amount of change that is meaningful from patient or therapist perspective
Carolina curriculum for infants and toddlers with special needs
- birth-24 mo developmental range
- criterior referenced, multi-domains
- determine approx. developmental level
bayley infant neurodevelopmental screener
- 3-24 mo
- norm referenced
- ID risk for delays or neurologic impairments
ages and stages questionnaire
- 1 mo to 5.5 years
- Parent/caregiver reports
- screening for developmental delays
motor skills acquisition in the first year checklist
- book and checklist by lois bly
- typical development for first year
Alberta infant motor scales (AIMS)
- birth - 18 mo
- observation only
- ID delay and maturation over time
- norm referenced
test of infant motor performance (TIMP)
- 34 wks post conception- 4 mo post term
- postural and selective control
Harris infant neuromotor test (HINT)
-screening for low and high isk infants 2.5-12.5 months
Baylesy scales of infant development
- 1-42 months
-mental, motor, behavior
-ID delay and monitor progress
-25-60 minutes - determine developmental level
norm referenced
