Standardized outcome measures Flashcards
Norm referenced test
Compares child to same aged peers (reference group)
Raw score is converted to a comparison to the mean
Often used to establish eligibility for services (state funded programs)
Comparison scores in norm reference test
Z score
Percentile rank
Age equivalent
Examples of norm reference test
AIMS
PDMS II/PDMS 3
BOT II/BOTMP
Criterion referenced test
Compares child to themselves
Determines baseline of performance to compare to over time and can measure progress
Expressed as % or raw score, or scaled score (points out of total points available)
Example of criterion referenced test
GMFM
Other functions of standardized outcome measures
Prediction + research
AIMS
Alberta infant motor scale
Measures motor development
Characteristics of AIMS
Observational scale; scored on what you see
Criteria for AIMS
0-18 months
OR
Until a child is walking
(whatever comes first)
Is the AIMS norm referenced or criterion referenced
Norm
What standardized test of motor development is both criterion and norm referenced
PEDI
What is the age equivalent score
Mean age represented by a test score
Unique to peds
Most layman friendly way to show development
Be careful with how much it is used; can be unhelpful and can limit showing strengths and how to maximize capacity
Only refers to one domain of development
What does it mean if age equivalent score is less than chronological age?
Indicates motor development delay
DMQ
Developmental motor quotient
Function of DMQ
Helps understand significance of delay by creating ratio
Developmental age/chronological age X 100
100 is normal/average
Least mature behavior
AIMS
Behavior closest to the left observed
Most mature behavior
AIMS
Behavior closest to the right observed
AIMS bracket
Formed between least and most mature behaviors
-Give one point for each behavior observed in the bracket
-Give one point for each point prior to the least mature behavior
How to determine chronilogical age
Subtract DOB from date of assessment
How to calculate corrected age
Used in babies born before 38 weeks
Subtract # of weeks premature from chronological age
Only performed until age 2 (residual delay will hopefully be grown out of)
Where should interventions be focused with the AIMS
Behaviors within the bracket not observed
Behaviors to the right of the bracket when all bracket behaviors are observed
PDMS-3
Peabody Developmental Motor Scales, 3rd edition
What is the PDMS 3
Standardized test of gross + fine motor skills, and physical fitness
Looks at major developmental milestones in young children
Age range for PDMS
birth-5 years
