Question | Answer |
---|---|
The single subject design is also known as what kind of design? | quasi-experimental |
The focus of single-subject designs is? | cause & effect |
What are the two core elements of the single-subject design? | repeated measurement, and design phase(baseline & intervention) |
What are the requirements of the baseline data? | identifiable target behavior, data stability or "consistency", and identifiable data trend or "slope" |
How many data points are needed in the ABA design? | 6-8 |
The target behavior must be ______ & _______. | observable and quantifiable. |
In single-subject designs the A = ? | baseline |
In single-subject designs the B = ? | intervention |
This design replicates one baseline phase following intervention. | A-B-A design |
The premise of this design lies in its ability to show that behavioral changes are evident only in the presence of the intervention. | A-B-A design |
Experimental control and clinical relevance can be strengthened through the use of which design? | A-B-A-B design |
What is the major advantage of the A-B-A-B design? | it provides two opportunities to evaluate the effects of the intervention. |
Which design tests replication of effects and internal validity? | A-B-A-B design |
What is the withdrawal design? | a design that involves withdrawal of the intervention |
What is judged by comparing the value of the target behavior at the last data point of one phase with its value at the first data point of the next adjacent phase? | The level |
This refers to the direction of change within a phase. | The trend |
one-tailed probabilities refer to what kind of hypothesis? | directional |
Two-tailed probabilities refer to what kind of hypothesis? | nondirectional |
what design assumes treatments are independent with different effects? | A-B-C-A |
what design can have interactive treatments? | A-B-BC-A |
change in level of performance, change in direction of trend, and looking at trend to see how target behavior is affectedis how data is analyzed in ____ design? | S-S |
what is the best estimate of trend line to identify change in behavior? | celeration line |
what is deltaY/deltaX or the high value/low value? | the slope |
this uses median score and significance test (binomial test) | split middle line |
what is used to analyze a data trend? | celeration line, slope, split middle line |
two standard deviation band, autocorrelation, "c" statistic, and the statistical process control-SPC are used to analyze ______ _____? | data consistency |
what is the calculation of baseline mean and STD to create a band of significance? | two STD band |
what is an agreement of test to itself ( 1 lag vs. 2 lag )? | autocorrelation |
what is the calculation of data trend using z scores? | the "C" statistic |
what is the analysis of variation "noise" in scores? | the statistical process control-SPC |
what are two types of reliability measures? | concurrent and inter-rater reliability |
what assumes external vailidity, has social validity, can be replicated and requires delineation of specific patient traits/treatment conditions? | generalizabilty of S-S design results |
what two things need to be addressed in order for generalizability to be made? | reliablity - ( measures extent to which a measurement is free from error) and validity - (measuring what you intend to measure) |
