What does PICO stand for? |
pt/problem, intervention, comparison/control tx, outcome |
|
|
Continuous data |
data that can assume any value along a continuous scale; ie distance, ROM, weight, time |
|
|
Discrete data |
data measured in whole units; ie HR, # of pt visits |
|
|
Dichotomous data |
a type of discrete data limited to only 2 values; it male or female, smoker vs non-smoker |
|
|
Qualitative data |
aka categorical data; categories distinguish non-numberic characteristics; ie eye color, blood type |
|
|
Quantitative data |
data consisting of numbers that represent counts or measurements |
|
|
scale of measurement: nominal |
aka classification scale; values of the variable are mutually exclusive and exhaustive categories; each person can only be assigned to one category |
|
|
scale of measurement: ordinal |
aka ranking scale; data are ranked on the basis of a property of the variable; ie MMT, levels of assist |
|
|
scale of measurement: Interval |
interval between adjacent values are equal, but there is no true zero; ie temp, some functional status tests |
|
|
scale of measurement: ratio |
intervals between adjacent values are equal and there is a true zero point; ie ROM, distance walked |
|
|
reliability |
the reporducibility or repeatablity of measurements |
|
|
alternate form of reliability |
aka parallel forms; assess consistency or agreement of a measurement obtained with another test; ie multiple forms of the NPTE |
|
|
Internal consistency |
measure of reliability; extent to which items or elements that contribute to a measurement reflect one basic phenomenon or dimension; ie a function assessment scale should only measure functional stuff |
|
|
intrarater reliability |
consistency of repeated measures made by the same person over time |
|
|
interrater reliability |
consistency of repeated measures made by different testers |
|
|
Test-retest reliability |
consistency of measurements made on the same test subjects on separate occasions |
|
|
Face validity |
degree to which a measurement appears to test what is says it's testing |
|
|
content validity |
degree to which a measurement reflects the meaningful elements of a construct and the items in a test adequately reflect the content domain of interest and no extra stuff |
|
|
construct validity |
degree to which a theoretical construct is measured by a test or measurement |
|
|
Criterion-related validity |
validity of the measurement is est by comparing it to a different measurement or to data |
|
|
concurrent validity |
a type of Criterion-related validity; compare against a gold standard |
|
|
predictive validity |
a type of Criterion-related validity; considered valid because it can predict a future behavior or event; ie GRE test scores predict how well a person will do in grad school |
|
|
prescriptive validity |
a type of Criterion-related validity; measurements suggest the form of tx a person should recieve; ECG determines defib or meds |
