What are the ultimate goal and Intermediate goals, facilitative goals or objectives?
What are
Random: by chance, normal fluctuations, cancel each other out
Systematic: bias, average score is influenced into a particular direction
What are:
Standardized measures
RAI’s
Observational Measures
Individual rating Scales
Client logs
What client would like to do, be or prefer to happen after the intervention is complete.
What are Other explanations for a score or alternative explanations ?
What are:
Confirm or disconfirm that the problem usually exists.
Determine whether the problem is getting better or worse and the pace of change if it is occurring
Provides an estimate of what would happen to the client without intervention.
A very specific versions of the ultimate goal:
(Who will do what by when under what conditions? )
What are the Intermediate goals, facilitative goals or objectives?
What are
Accuracy: validity
Consistency: reliability
What are:
The B design is a single phase (intervention only) design.
The most frequently used single subject design.
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 are:
Validity
Reliability
Measurement error
Utility
Directness
What are:
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 are
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 ?
Why we use Coefficient Alpha/ Cronbach Alpha for.
What are
Used to quantify internal consistency/ reliability
The higher, the better, best possible=1
0.70= adequate
Greater than .80 very good reliability
What are:
Nominal: categories
Ordinal: categories in a certain order
Interval: equal intervals
Scale: equal intervals and 0 point.
What are:
Reliable
Valid
Sensitive to change
Non-reactive
Direct
Easy to use
Accessible
Relevant to intervention planning
