Validity
The extent to which a test is subjectively viewed as covering the concept it purports to measure
The degree to which a research instrument produces consistent results
Observing behavior which is spontaneously occurring in the participant's own natural environment.
What is Naturalistic Observation
Consistent, giving similar results under similar conditions
Allows for measurement of change over the course of an intervention
What is the B (Intervention Only) Design
The extent to which a measure represents all facets of a given construct.
Measures test consistency
What is Test-Retest Reliability
Where we're observing behavior under conditions which are controlled by the researcher,
Measures what it is supposed to measure
Two phase design consisting of a no-intervention baseline phase (A) and an intervention phase (B)
It is a quasi-experimental design
What is the AB (Baseline and Intervention) Design
The degree to which a test measures what it claims, or purports, to be measuring."
A measure of reliability obtained by administering different versions of an assessment tool (both versions must contain items that probe the same construct, skill, knowledge base, etc.) to the same group of individuals.
What is Parallel-Form Reliability
Where the researcher becomes involved in the everyday life of the participants, either with or without their knowledge.
What is Participant Observation
Measure does not change the target by the simple act of measurement.
If a change occurs during B and is reversed during the second A, change is most likely associated with presence or absence of the intervention
What is the ABA (Basic Withdrawal) Design
The extent to which a measure is related to an outcome and is often divided into concurrent and predictive validity
What is Criterion validity
When different instrument items (questions on a survey) are trying to measure the same construct and are compared to determine if they produce similar results
What is Internal Consistency Reliability
Used to sample behavior in observational research. It is where an observer records the number of times a certain behavior occurs.
Measure most accurately represents the real target, goes to the heart of the concept that you are trying to measure.
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 a BAB Design
When the decisions from different raters are compared to each other to see how consistent the rater’s decisions are.
What is Inter-Rater Reliability
Method that involves the acquisition of representative samples by observing subjects at different time intervals. These time intervals can be chosen randomly or systematically.
Easy to obtain
what is a Multiple Baseline Design
