observe any change

Q

what is a good outcome measure

A

easy to administer

not inconvenient the patient

relevant/applicable to clinical setting

assists in classifying the patient’s

impairment/ setting goals / prognosis and assessing response to intervention

has good psychometric / measurement properties

Q

what are the 3 main reasons why we use objective measures

A

discriminate between impairment level of each patient

determine prognosis

evaluate change in status over time

Q

what are latent traits? examples

A

pain, disability, balance

typically cannot quantify objectively how much of each of these are present but it can be seen or discussed

ie = balance can be improved but cannot be quantified across every patient

Q

pros of clinician administered / performance based testing

A

removes bias from patient’s old perception of impairment
can clearly see and measure the impairment

Q

what are patient administered / patient-reported outcome measures

A

outcome measures that rate the impact of injury on broad range functions and ability to participate in life roles

typically have an associated frame of reference

21
Q

what are the categories of absolute error

A

standard error of measurement
minimal detectable change

22
Q

what is standard error

A

error associated with inherent variability of the device

23
Q

how is intra/interrelater reliability decreased

A

measurement device is calibrated

rater or two different raters use consistent techniques

there is a change in clinical status where condition improves

24
Q

what is test-retest

A

patient complete a self-reported measure at one point in time, then retested after a short time interval

25
Q

what does test-retest do? how is reliability assessed?

A

assess the extent to which the scores obtained for both the test and retest agree

less difference between test and retest = more reliable

26
Q

what is test-retest reliability crucial for

A

patient reported outcomes involved self-assessment of impairment on a scale

ie pain rating

27
Q

what is used to determine relative reliability

A

intraclass correlation coefficient (ICC)

28
Q

describe the ICC

A

between 0 and 1
0 - worst / 1 - perfect reliability >0.75 = very good
>0.90 = excellent

29
Q

what is the kappa coefficient

A

Metha’s Definition:
Less common and used for measures where the score of the measure is dichotomous

Mine: interrater reliability

30
Q

decribe the kappa coeffecient

A

0- worst / 1 - perfect score
K > 0.7 = acceptable

31
Q

how is standard error measurement recorded in units

A

same unit as original measure

32
Q

what is validity

A

assesses the trait or health domain that it is supposed to assess in a comprehensive way

33
Q

what is content validity

A

measure is comprehensive and has all possible questions/items to measure the trait of interest

34
Q

what is criterion / construct validity

A

addresses the necessary aspect of the construct it intends to measure

35
Q

what is reliable but not valid

A

a bunch of darts thrown in the same spot but not in the center

36
Q

what is valid but not reliable

A

darts all over the board in no particular pattern

37
Q

what is neither reliable nor valid

A

darts on all the top half of the board but in no particular order

38
Q

what is both reliable and valid

A

all darts in the center of the board

39
Q

what is responsiveness

A

ability of a measure to detect change when the patient’s underlying condition is improved or deteriorated

40
Q

how is responsiveness measured

A

using effect sizes - measures standardized rate of change

41
Q

what are common values of effect size

A

> 0.8 = very good
1 = excellent

42
Q

what does responsiveness not tell you

A

how to interpret change in score of a measure
whether the change in score is big enough to conclude that there is a true improvement

43
Q

what is used to interpret change in status

A

minimal detectable change
minimal clinically important difference

44
Q

what is minimal detectable change

A

minimum change in score required to be confident that a “true” or statistically important change has occurred

45
Q

what does MDC___ mean

A

underline = a #
MDC95 = 95% sure that a true change has occurred

46
Q

what is the minimal clinically important difference

A

minimum change in score required for patient to report the recovery is meaningful to them

47
Q

what are synonyms for MCID

A

MCIC - minimal clinically important change

CID - clinically important difference
CIC - clinically important change

48
Q

what are patient acceptable symptom states

A

lelve of a symptom state that patient considers themselves “well”

49
Q

what is the PASS for pain?

A

<3/10

50
Q

what determines short based goals vs long term

A

short - MCID
long - PASS
