SINGLE SUBJECT DESIGNS
Pre-experimental (AB) outcome X change from baseline levels with the introduction of intervention B
What is the advantage and disadvantage of the Pre-experimental AB design
Ultimate Goal
What are Ultimate goals in treatment plans ?
Levels of Measurements
What are the levels of measurements ?
B design
True or False 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.
True experimental design in that it allows for causal inference.
What else does this design do ?
Withdrawal (ABA/ABAB) outcome X covary with introduction and withdrawal of intervention B
What is the ABA/ABAB advantages and disadvantages of this single subject design?
Intermediate goals, facilitative goals or objectives
What is the meaning of Intermediate goals, facilitative goals or objectives in treatment planing when engaging with clients ?
Characteristics of measurements
List the key characteristics of measurements?
Intervention/ design.
What is the most frequently used single subject design?
Baseline
Meaning of Baseline
Multiple-baseline/multiple-probe outcome X change from baseline levels with the introduction of intervention B over multiple participants, responses, settings, etc.
What is the advantages and disadvantage of multiple-baseline design ?
Accuracy: validity
Consistency: reliability
In any measurement we strive for?
B design is a single phase
The B design is a single phase or intervention only design.
Baseline are useful
How are Baseline useful ?
ABA or Multiple Base Line
What single subject design does this represents; Does not require withdrawal of intervention, Appropriate for non reversible behaviors.
Coefficient Alpha/ Cronbach Alpha
True or False; Coefficient Alpha Cronbach Alpha is
Used to quantify internal consistency/ reliability The higher, the better, best possible 0.70= adequate Greater than .80 very good reliability
Patterns or No Pattern
What are the different types of patterns?
AB or ABA single subject design
What single subject design does this represents Quick and efficient to implement.
• Appropriate for low-stakes decision making.
• Does not control for threats to internal validity; not an experimental design.
terms of validity
What are the two ways measurement can go wrong in terms of validity?
