Clinical Assessment of Psychological Trauma and PTSD Flashcards
a) Best method approach for conducting assessment for PTSD (& what it approach includes)
b) Evidence based practices means:
c) Relibility statistics: range is between ___ and ____%. The lowest level of reliability is ____%.
d) Interrater reliability means
e) Test retest reliability
f) Internal consistency
a) Multi-method approach = multiple forms of information about the client should be gathered.
b) Evidence based practice = practice standards and professional accountability that are based on empirical evidence.
c) Reliability estimates range between 0 (completely unreliable) and 1.00 or 100% (perfect reliability). The lowest level of reliability considered acceptable is generally a reliability of 0.80 or 80%
d) Interrater reliability, is the extent to which two independent interviewers or raters agree in their scores for the same person on the same measure. Both raters must be blind (meaning unaware of the other raters responses). If the raters agreed all of the time, then the interrater reliability would be perfect. If their ratings were unrelated then the interrater reliability would be zero
e) The extent a test yields relatively similar scores for the same individual over time.
f) is the extent to which the questions all measure aspects of the same overall phenomenon
a) A “measure of validity” is….. (generalised meaning)
b) ‘Face’ or ‘content’ validity
c) Construct Validity
d) Concurrent validity
e) Discriminant validity
a) Establishing that the measure actually measures what it is supposed to measure.
b) ‘Face’ or ‘content’ validity, refers simply to whether the test appears (at face value) to measure what it claims to
c) Construct Validity, refers to the degree that a test captures a specific theoretical construct (phenomenon). The more evidence a researcher can demonstrate for a test’s construct validity the better
d) Concurrent validity refers to the degree a test corresponds to an external criterion that is known concurrently (i.e. occurring at the same time). If the new test is validated by a comparison with a currently existing test measuring the same thing and known to have good validity already the new test is said to have concurrent validity
e) Discriminant validity is the degree to which a measurement does not correlate with other measurements that assess different concepts, a measure of PTSD not associated with a non- trauma measure would indicate discriminant validity
