standardized testing Flashcards
what do criterion referenced tests compare the child to?
him/herself
what does a norm referenced test compare the child to?
standardized groups of “normal” children
what is reliability?
are the results repeatable?
what is validity?
does the test measure what u wanted it to measure?
what is sensitivity?
ability of the test to detect dysfunction or an abnormality (true positive)- MRI, if it says u don’t have it, u CAN RULE IT OUT! It won’t say u have it if u don’t…
what is specificity?
ability of the test to detect normality
PREGO TEST- rules it IN, if it says u have it, u have it, does not give false positives, might give false negatives, so if it says negative, u may still actually be pregnant… this wont say u don’t have it if u do…
raw score
number of items correct
age-equivalence
average age of normative sampule who achieved the score
developmental quotient
ratio between child’s actual score and child’s age
standard scores
Z score and Tscore, expressed in terms of standard deviations
which score is expressed in terms of standard deviations?
Standard scores
percentile rank
compare score to normative sample
percentage
passed items out of total number of items measured
What age is the INFANIB test for?
1-18 mo.
what is the purpose of the INFANIB
examine neuro fxn
time to administer the INFANIB
20-30 min
is the INFANIB criterion or norm referenced?
criterion
what is the gold standard for measuring ID developmental delay
Bayley III
age for AIMS test
birth to 18 mo.
purpose for AIMS
ID motor delay
time to administer AIMS
20-30 mins
how is AIMS referenced?
norm referenced
age fro Bayley III test
1-42 mo. (3.5 yrs.)
purpose for Bayley III
ID developmental delay
time to administer the Bayley III
25 min-1 hr.
reference for Bayley III
norm referenced
age for PDMS-2
1-72 mo. (1-6 yrs)
what is the long name for PDMS-2?
peabody developmental motor scales
purpose of PDMS-2
estimate motor competence
time to administer PDMS-2
45-60 min
reference type of PDMS2
norm referenced
how do u find a basal age in the PDMS-2
get 3, 2s in a row
how do u find a ceiling age?
get 3, 0s in a row
name the 3 sections of a premie neuro
neuro
movement
responsiveness
only use the responsiveness section of the premie neuro test if the child is ______ wks old and not____________
28 wks, not on a vent
benefits of premie neuro
use on children younger than 28 wks., non-invasive
8 parts of the neuro exam of the premie neuro
arm recoil arm traction palmar grasp plantar grasp scarf sign popliteal angle heel to ear movement type
8 parts of the movement exam of the premie neuro
tremors thrashing facial grimace startle yawn color change arm movement leg movement
8 parts of the responsiveness section of the premie neuro test
>arm flexion >head lag >held sit >posterior neck >anterior neck >alert >ventral suspension >responsiveness
how do u score a premie neuro
give each item a 0-5:
0-1= abnormal
2-3= questionable
4-5= normal
how to perform arm recoil
hold baby’s arms down and then watch to see if she recoils them to flexed position
how to perform arm traction
pull baby’s arms and she should pull back
where to press foot for plantar grasp
on forefoot so they curl toes, heel will= withdrawl, not grasp
perform scarf sign
passively move baby’s arm over their chest and neck like a scarf, premies elbow will move past midline, full term baby’s elbow will not go past midline
popliteal angle
place thighs on baby’s tummy and try to extend their knees, premies may be able to extend all the way but full term babies should not be able to extend past 90 degrees
heel to ear
premies= heel to ear, full term= not able to get all the way there
startle
ring a bell by baby’s ear and see if their faces change at all or attempt to look at sound, do they recognize it’s a new sound
yawning
do they yawn in the 10 mins ur doing the test?- self calming mechanism
color change
baby should be relaxed and should not have color change throughout the test, a way to measure self calming
arm flexion
spontaneously where are the arms most of the time
head lag
pull baby up with arms, do they pull their head the rest of the way up, then once they are up does head fall forward?
held sit
hold baby in sit, how long does it take before u have to help them with their head. 0,1= they can’t hold head at all w/o support, etc.
anterior/posterior neck
hold baby in sitting, rock baby back and forth, do they right their heads?
ventral suspension
hold baby in your hand on their tummy, do they kick their legs, bring arms to face? squirm at all?
alert
how alert baby is during test in general
responsiveness
how responsive are they?
in a bayley III, where do u start
at their age reccommeded spot
where do u stop in a bayley III
when they get 5, 0s in a row
what if the child can’t perform the recommended starting point?
go back until they get 3, 1s in a row
