Measures
100
Reliable: consistent, giving similar results under similar conditions
What is a Characteristic of a good measurement?
100
Single Subject Design
What is the backbone of Practice Evaluation
100
Only B design does not allow for evaluation of pre-intervention status, we do not know if there is a relationship between intervention and outcome.
What is the most frequently used single subject design
100
Allows for evaluation across clients, situations, or problems
What is multiple baseline design
100
Just about anything that people do
What is behavior
200
Regarding Reliability
What is a question to ask when evaluating measurement instruments
200
what you will not see is problems but these
What are indicators
200
Two phase design consisting of a no-intervention baseline phase (A) and an intervention phase (B). The existence of a baseline allows for the establishment of a relationship between intervention and outcome. Susceptible to uncontrolled influences of extraneous variables (the non-spuriousness issue in causal inference), especially the history threat to internal validity
What is AB (Baseline And Intervention) Design
200
period of time during which an outcome is measured repeatedly in the absence of the intervention
What is baseline
200
purposes of practice evaluation
What is behaviors are countable
300
At the very minimum, the instrument should appear to measure what it is supposed to measure.
What is Do the items appear to have face validity?
300
Focus on one problem and define it as specifically as you can.
What is how do you select a target?
300
Sometimes an individual’s behavior is so severe that the researcher cannot wait to establish a baseline and must begin with an intervention.
What is In this case, a B-A-B design is used. The intervention is followed by a baseline followed by the intervention
300
ensure control similar to the control group in experimental design
What is baselines
300
– Most direct expression of the problem Have great deal of validity Great reliability Precision Very useful Flexible
What are advantages of behavioral measures
400
Behaviors are measurable.
What is For our purposes in practice evaluation
400
Something you can measure
What is a definition of a target?
400
period of time during which an outcome is measured repeatedly in the absence of the intervention
What is baseline
400
Confirm or disconfirm that the problem usually exists.
What are are baselines useful
400
Frequency Duration Interval counts
What are three ways of measuring behavior
500
Frequency Duration Interval counts
What is Three Basic Ways of Measuring Behavior
500
what client would like to do, be or prefer to happen after the intervention is complete.
What are Ultimate goals
500
-A relationship must exist between the two variables - The relationship must be non-spurious. -There should be a time interval between one variable and the other
What is There are three conditions that must be established before we call a relationship casual.
500
patterns or no patterns
What is In the baseline phase, measurements are taken until a pattern emerges
500
Observational measures are portable Observational measures are non obtrusive
