Standardized Measures Flashcards
What is an infants and child’s HR compared to an adult?
Adult (60-100)
Child (80-120)
Infant (100-140)
What is an infants and child’s BP compared to an adult?
Adult (120/80)
Child (100/60)
Infant (80/40)
What is a standardized test?
Task or set of tasks given under standard, set conditions, with rules for administration and scoring
What are discriminative tests?
Discriminates performance of individual relative to norm-referenced sample
What are evaluative tests?
Designed to measure change of performance over time
What are predictive tests?
Designed to predict later outcomes
What are the characteristics of discriminative tests?
Norm referenced
Comparison to peer performance
Normal distribution of scores
Individual vs peers
Not sensitive to effect of intervention
What are the characteristics of evaluative tests?
Criterion-referenced
Pre-determined criterion
Individual vs himself
Sensitive to effects of intervention
What is validity?
How well does a test measure what it is designed to measure
What is inter-rater reliability?
Agreement between two or more raters of same test
What is intra-rater reliability?
Consistency within same rater
What is test-retest reliability?
Evaluates reproducibility of test results over 2 different administrations on same subject
What is internal consistency?
Measure of the correlations between different items on the same test (how well the items measure the same construct)
What is responsiveness?
Ability of an outcome measure to detect change over time
What is the MDC (minimal detectable change)?
Absolute reliability
Identifies potential test error
Not a measure of meaningful change
What is the MCID (minimal clinical important difference)?
Quantifies change important to patient
Relies on external criterion
What is the raw score?
Number of items correct
What does age equivalence mean?
Mean age when 50% of children would have tested similarly
What are standardized scores?
Expressed in terms of of standard deviations and easily visualized on a bell curve
What does percentile mean?
Indicates percentage of scores that fall below a particular value
What is considered below the average score for common norm-referenced tests?
1 standard deviation
What do standard scores often have a mean of?
100
What do scaled scores often have a mean of?
10
What is the capacity of a child?
What the child can do
What is the performance of the child?
What the child actually does
What does the APGAR scale measure?
Have vigorous a baby is right after birth (higher score is better)
If an infant scores a 7 or less at 5 minutes on the APGAR scale what does that mean?
They are at an increased risk for neurological deficits
What does APGAR stand for?
Activity
Pulse
Grimace
Appearance
Respiration
What is the dubowitz/ballard assessment used to determine?
Gestational age
What is the Brazelton Neonatal Behavioral Assessment Scale used for?
Measures a newborns functioning
Regulates breathing, temp, and autonomic system
Quality of infants tone, activity level, and reflexes
What does the Alberta Infant Motor Scale good at predicting?
The delay of independent walking in a child
What is the Test of Infant Motor Performance good at predicting?
Delay of head control in a child
What is the Bayley Scales of infant and Toddler development good at predicting?
If a child is delayed in sitting independently
Know how to calculate chronological age and adjusted age (slides 50-53 on module 2 asyncs)
