Exam 11: Basic Principles of Single-System Designs

Repetition of a given intervention by the same practitioner in order to generalize is called:

Internal validity refers to the measure actually measuring what it purports to measure.

In an A-B-A-C design, one can make a clear comparison of the two interventions.

Interpretation of the design, A-B-C-D-C-=, is complicated mainly by:

Threats to the validity of some conclusion you reach in a single-system design means that logically, the same outcome could have occurred because of reasons other than your specific intervention.

If you validated shame aversion therapy in your clinic with exhibitionists, and I validated it in my setting with nose fetishists, this would be an example of:

The key aspect of the intervention period that distinguishes it from a non-intervention phase is that the intervention is:

The key assumption of the baseline/intervention comparison is that the baseline pattern will be more variable in the next period if there is no intervention.

When a client observes a difference between two interventions, this is called:

The maintenance phase with the following notation suggests that the original intervention has been continued but with a brand new maintenance plan added: A-B-BC.

The generic term for any design in which the original intervention is taken away is:

The major difference between the baseline and intervention phase is that no formal intervention goes on in baseline, while observation of the target event does go on in both phases.

Training, maintenance, and follow-up are all types of phases in single-system design.

A single technique could properly be designated as BC.

The designation "D" could stand for a single technique or a combination of several techniques, but it does not stand for an entire intervention program.

During the intervention, Manu got married and his test scores showed significant improvement. The most likely threat to internal validity this poses is:

A phase is a period of observation and/or service activity that is distinct from all other periods. (Reminder: Keep in mind return to baseline phases. Are they identical or not?)
