DESIGNS
The only design that does NOT allow for evaluation of pre-intervention status.
B Design
Structured diaries of events that are relevant to the target that can be kept by the client, the practitioner, or a significant other in the client's environment.
Logs
The specific object of intervention that is relevant in a given situation
Target
Mental images that summarize a set of similar observations, feelings, or ideas.
Concept
The consistency of an instrument.
Reliability
Baseline and intervention design
AB Design
Instrument used with individuals, families, and/or groups to measure intensity of feelings, internal states, etc.
Individual Rating Scales
This includes identifying the problem that the client prefers to start with or about which (s)he is most concerned and determining which problem has the greatest potential to produce negative consequences if it is not handled.
Prioritizing problems
The process of specifying what we mean by a term.
Conceptualization
This occurs when different instrument items try to measure the same construct and are compared to see if they produce similar results.
Internal consistency reliability
Design that allows for pre-intervention, intervention, and post-intervention evaluations.
ABA Design
Short and easy measure that allows the client to disclose sensitive information that he/she may not be able to verbalize.
Rapid Assessment Instrument
This is the client's preference about the future: what (s)he would like to have happen when the intervention is complete.
Ultimate goal
Level of measurement that includes absolute zero.
Ratio
Clear conceptualization, standardization, increase the number of items on an instrument, use a more precise instrument, use multiple instruments, and pilot retesting and replication
Ways to improve reliability
This design controls for threats to internal validity by varying the lengths of the baselines.
Multiple Baseline Design
Series of structured questions or statements designed to elicit information from a client.
Standardized measurement scale
What the client will think, feel, and do when the problem no longer exists.
Objective
This is the change in a scale score from one time to another that is more than what you would expect based on measurement error alone.
Standard of Measurement Error
The accuracy of an instrument
Validity
Design that can be used with individuals whose behavior is so severe that the researcher cannot wait to establish a baseline.
BAB Design
Includes sampling, naturalistic, controlled, and participant studies.
Observational Measure
Change is considered this if it could not have happened by chance alone.
Statistically significant.
This assigns meaning to a concept in terms of the activities and operations needed to measure it.
Operational definition
The two ways in which construct validity is established
Convergent validity and discriminate validity
