B7-078 Psychiatric Assessment Flashcards
consistency of a test
reliability
how much a test measures what it is supposed to
validity
a valid test appears to measure what it should
face validity
a valid test can predict a score on another metric
criterion validity
obtained experimentally, a valid test is highly related to other test scores that it should be and highly unrelated to tests it shouldnt be
construct validity
the proportion of individuals with the condition of interest that are correctly identified as having the condition of interest
sensitivity
the proportion of individuals without the condition of interest correctly identified as not having the condition of interest
specificity
the proportion of individuals with a positive test result that are correctly diagnosed and have the condition of interest
positive predictive value
the proportion of individuals with a negative test result that are correctly diagnosed and do not have the condition of interest
negative predictive value
how to calculate sensitivity, specificity, PPV and NPV using the 4 square method
calculation for Z score
allows you to compare score to broader population
symptom checklists are […] band measures
narrow
(PHQ-9, FAQ, GAD-7, etc)
personality inventories are […] band measures
broad
(MMPI, PAI, MCMI, etc)
projective tests, like the Rorschach test, are […] band measures
broad
standard cutoff of impairment for MMSE
23
is the MOCA or MMSE better for evaluating executive function?
MOCA
(is more comprehensive in general)
standard cutoff for impairment of MOCA
26
[MMSE/MOCA] takes education into accout
MOCA
what is the niche of clinical neuropsychologists?
best at determining functional impact of neuropsych conditions
screening tests should be designed to maximize [sensitivity/specificity]
sensitivity
percentile ranks are […] transformations of standardized scores
non-linear
representative group of individuals to compare to individual’s test score to
normative group
the consistency and reproducibility of a test
reliability
the closeness of a test results to the true value
validity
examples of ways to assess reliability [4]
test-retest
split half
interrater
alternative forms
examples of ways to assess validity [3]
construct
face
criterion
a score derived from a comparison to a broader population of interest
standardized score
percentage of scores in its frequency distribution that are equal to or lower than it
percentile rank
cognitive domains assessed by neuropsychological tests
processing speed
attention
memory
language/speech
visual-spatial
executive function
emotional/behavioral function
performance validity
if the test does not measure what you intend it to measure, it has low […]
validity
if scores are similar or consistent across time points your test has high […]
reliability
how much a test item appears to measure what it is supposed to measure
face validity
by changing the items on the test to look more like the symptoms of what you are testing for, you are increasing […] validity
face
the percentile rank for -1.00 is
16
the percentile rank for -2.00 is
2
the percentile rank for 0.00 is
50
the percentile rank for +1.00 is
84
the percentile rank for +2.00 is
98
factors commonly controlled for in computation of standardized score [4]
age
education
sex
race/ethnicity
how accurately a test measures what it’s intended to measure
validity
consistency of test results when administered under the same conditions
reliability
process of administering the test to a diverse and representative sample population to establish norms
standardization
