SSD Flashcards
When planning a SSD, one needs to pay attention to whether improvement is simply the tendency for people to move toward the average or ______. This is a threat to internal validity.
Regression Toward the Mean
In a SSD and beyond when there is further decline (if desired) or stability in the 2nd observation period.
Treatment Carryover
A SSD design where
- A pre-test is given (baseline);
- Treatment is given; &
- A post-test is given.
ABA Design
When conducting a SSD, one needs to pay attention to whether there is an event that is coinciding in time with the intervention that may have caused the change in the client’s behavior, rather than the intervention. This is a threat to internal validity.
History
Using more than 1 measure of the same target behavior.
e.g., To measure depression, a social worker documents the client’s appearance at each visit AND administers the Beck Depression Scale.
Triangulation
This research design looks at changes in 1 individual, 1 family, or 1 group, over time.
Single System Designs (SSD)
The more variation in a target problem, the _____ baseline needs to be.
longer
A type of ________ validity that asks, “Did experiment stimulus really cause a change in the dependent variable?” Or was it something else (e.g., maturation).
Internal Validity
When conducting a SSD, one needs to pay attention to whether a change is behavior is due to the client naturally maturing, rather than responding to the intervention. This is a type of threat to the internal validity.
Maturation
When conducting a SSD, one needs to pay attention to whether a behavior change is due to the person being watched, rather that the treatment causing the change. This is a type of EXTERNAL Validity.
Reactivity
To increase _____ validity, social workers ought to repeat SSD with many clients to see if the causal relationship may be generalizable.
External Validity
