Practice Evaluation Basics
Validity and Reliability
Measures
SSD's
100
This is the backbone of practice valuation
What is single system design?
100
How well an instrument covers the range of meanings included within a concept that is being measured
What is Content Validity?
100
Nominal, Ordinal, Interval, and Scale
What are Levels of Measurement?
100
A design with a Baseline phase and an Intervention phase
What is an AB design?
200
This type of definition gives us something that we can measure
What is an Operational Definition?
200
This is established through convergent validity and discriminant validity
What is construct validity?
200

Validity , Reliability, Measurement Error, Utility, Directness 


What are Key Characteristics of all Measures?
200
The most frequently used single subject design (non-experimental)
What is the B (Intervention Only) design?
300
These are specific, measurable, achievable, realistic, and time-limited
What are SMART goals?
300
The degree to which a research instrument produces consistent results
What is reliability?
300
Accuracy and Consistency
What are Validity and Reliability?
300
This design contains and ends on a withdrawal phase and can possibly show causality 
What is ABA design?
400
In practice, you won't see problems, you will see these instead
What are Indicators of Problems?
400
When different instrument items are trying to measure the same construct are compared to determine if they produce similar results
What is Internal Consistency Reliability?
400
These can be random or systematic
What is Measurement Error?
400
For this to be established, a non-spurious relationship must exist between two variables with a time interval between them
What is causality?
500
These range from single techniques to multi-element programs
What are Interventions?
500
Using a self-report, a report by someone else, and direct observation help to improve this
What is Reliability?
500
If it's at least .70, it's adequate. It if it's great than .80 reliability, it's very good
What is the Coefficient Alpha or Cronbach's Alpha?
500
The degree to which we say an independent variable (intervention) causes change in the dependent variable (target)
What is Internal Validity?
