Chapter 9 Single Subject Design

Evaluating individual progress over time.

1. Selecting the target outcome
2. Selecting the intervention
3. Selecting the measurement tool.
4. Collecting intervention data.
5. Conducting the analysis (compiling the results.)

1. AB (one baseline and one intervention)
2. ABA (which adds an additional baseline)
3. ABAB (which repeats the baseline and intervention).
4. ABC (which introduces a new intervention.)

A technique used to facilitate a change in research.

Standardized measures because they are convenient and have established reliability and validity.

It is used as a reference point to which any targeted change in the individual following intervention as compared. Also known as a starting point.

1. Graphing the results and examining the graph to see if a change has occurred over time. Eyeballing the results.

AB- this is because it has one baseline measure and one intervention.

To be more certain that it was the intervention that was responsible for the change (and not due to some outside influence)

A withdrawal of the intervention and returned to the baseline.
This means to continue to measure the participant after the completion of the intervention.
*An example is a student acting out were the behaviors are charted, then seeing if the behaviors continue after the intervention ceases.

To target outcomes that require more than one intervention.
*This design works the same as AB except that it utilizes multi-interventions.
*These interventions are introduced in sequence.
