interpreting the data

peabody - how to

- find your Basal and double that item number

- then add any additional items that are 2 or 1 until your ceiling

- this number is the total raw score

percentile rank

where the individual ranked within the normative sample of age matched peers

95% confidence interval

the range of which you can be 95% confident that the child would score between those numbers if all of the other descriptors were all the same

- task, environment, and behavior

descriptive term

- impaired or delayed

- borderline impaired or delayed

- below or above average

- average

using your data

- find the raw score for either body control or body transport

- locate your item on the chart

- find the age equivalence

inter-rater reliability

- for age 1-5 months had some fair to good reliability

- all other ages on all tests had good to excellent reliability

SEM for peabody

for all individual subtests at all ages is 1

- for composite gross motor

- months 1-5 = 5

- months 6-10, 11-15, 16-24 = 4

- all others is 3

if the SEM is 5 what does this mean?

the child must score a 6 on the peabody to be out of error

test-retest for peabody 3

intra-rater reliability >.95 for all ages and all subtests and composite testing IF done in a 2 week window

- peabody 2 = 1 week window

cut off score for developmental delay

- 90

- sensitivity and specificity

- true vs false positives

- true vs false negatives

correlations with age

- body control for all ages .95

- body transport for all age .96

- object control for all testable ages .91

- hand manipulation for all ages .95

- eye-hand coordination for all ages .96

- physical fitness for testable ages .69-large

BOT 2 - scoring

take your raw score and convert each item to a point based on the table

- add up all point score in each subtest to get a total point score

total point score - scale score

each subtest total point score is converted to a scale score (sex and age specific)

- the sum of those are then converted to a standard score for each composite

- fine manual control

- manual coordination

- body coordination

- strength and agility

the BOT test is used to show what?

- change

- eligibility

cutoff score

sensitivity and specificity
