Measurement
Nominal

Scale
Interventions can be either. . .
What is simple or complex?
Has there been any change in the area of concern?
Is there a functional relationship between the intervention and the observed change?
What are two issues in a single subject design?
Narratives
Video tapes
Audio Tapes
Computer Applications
What are methodologies for describing interventions?
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 the three conditions that must be established before we call a relationship causal?
Individual
Family
Group
Organizational
Community
Social levels
What are levels at which interventions can be developed?
B (Intervention Only) Design
AB (Baseline And Intervention) Design
ABA (Basic Withdrawal) Design
Multiple Baseline Design
What are the types of single system designs?
Frequency
Duration
Interval counts
What are the three basic ways of measuring behavior?
Validity
Reliability
Measurement error
Utility
Directness
Knowledge development
Rigorous description of intervention leads to more precise implementation
Administrative purposes: for case documentation, case transfer and supervision.
History
Maturation
Testing
Instrumentation
Statistical
Regression
What are threats to internal validity?
Most direct expression of the problem
Have great deal of validity
Could be administered in a way to ensure great level of reliability
Precision
Very useful
Flexible
What are advantages of behavioral measures?
Standardized measures
Observational Measures
Individual rating Scales
Client logs
What are the persons and the agencies involved?
What information/ message was conveyed to the client?
Where did the intervention take place?
When did the intervention take place?
How was the intervention implemented?
What are components of a fully specified intervention?
Allows for evaluation across clients, situations, or problems
True experimental design in that it allows for causal inference
Useful for evaluating situations where an intervention would be likely to bring about enduring changes in the dependent variable
What are multiple baseline designs?
