Lecture 2 Flashcards
Types of Tests and measures
Observations and Outcome measures
2 types of outcome measures
Clinical Based and Patient-centered (Self-Report)
Patient centered assessments: Pros and Cons
pros: info relevant to pt, wide range, easy, fast, inexpensive
cons: limited by pt interpretation, number of tasks limited, psychosocial factors, unintentional inaccuracy
what type of response is yes and no response?
nominal measures
what type of response is measured in rank order, not equal intervals?
ordinal measures
what type of response has equal intervals between responses
interval/ratio measures
a ______ instrument measures a phenomenon dependably, time after time, accurately, predictably, and without variation
reliable
a tested measure should demonstrate:
_________ stability (over time)
_________ reliability (within the same rater)
_________ reliability (between raters_
test-retest
intra-rater
inter-rater
face validity is
the idea that the instrument measures what it claims to measure
content validity is
the idea that the subcomponents of the instrument adequately cover the entire construct
what effect results from an activity that is too difficult?
floor effect
what effect results from an activity that is too easy?
ceiling effect
the amount of change in a variable that must be achieved to reflect a true difference, not by error or chance
minimal detectable change(statistical)
the smallest difference in a measured variable that signifies an important rather than trivial difference in the patient’s condition
minimal clinically important difference (clinical)
Global disability/ QoL measures what?
patient’s overall disability (regardless of
condition) or measures Quality of Life
Goal of QoL
To capture a broad range of health status facets
Global disability/QoL: Pros and Cons
Pros: variety of pts, extensive normative data
Cons: sacrifice depth for broadness, irrelevance to some conditions, less sensitive to changes
ADL measures: Pros and Cons
Pros: overall function, real-world view
Cons: limited number of activities, too basic for some pt
ADL measures are dependent on what the ___________ identifies as essential
individual
Cognitive/Affect Measures: Pros and Cons
Pros: more detailed assessment in an area, wide range of clinical pop
Cons: may not change in response to PT, limited in scope
Goal of Diagnosis-Specific measures
assess the patient’s perception of the effect of a specific disease
Diagnosis-Specific measures: Pros and Cons
Pros: relevant content for condition, more likely to detect imp changes over time
Cons: applicable to specific pts, unlikely to detect changes in broad aspects of QoL
Arthritis Measures
Arthritis Impact Measurement Scale – version 2 (AIMS)
Western Ontario McMaster Arthritic Category (WOMAC)
Spine Measures
Oswestry Disability Index (ODI)
Roland Morris LBP Disability Questionnaire (RMQ)
Neck Disability Index (NDI)
