Causality in Single Subject Designs
Definitions
Types of SSD's
100

What are three conditions that must be established before we call a relationship causal?

1. A relationship must exist between the two variables

2. The relationship must be non-spurious.

3. There should be a time interval between the independent variable and the dependent one.

100

What is the effect that is the result of a tendency for subjects selected on the bases of extreme scores to regress towards the mean on subsequent tests. 

Statistical regression 

100

What is a single phase design?

The B design

200

What is it called when, some un-anticipated event occur while the evaluation was in process and did these events affect the dependent variable? 

History

200

This type of design allows for evaluation across clients, situations, or problems.

Multiple baseline designs

200

What is the most frequently used single subject design?

The B Design

300

What is it called when there were changes in the dependent variable due to normal developmental processes operating within the subject as a function of time? 

Maturation

300

What is a purposively implemented change strategy? 

An intervention
300

This design consists of a no-intervention phase and an intervention phase.

  AB Design

400

What is it called when the pre-test affect the scores on the post-test? 

Testing

400

This is a methodology for describing interventions that includes practice manuals, process recordings, or written descriptions. 

Narratives

400

This is a three phase design and it allows for evaluation of pre-intervention, intervention, and post-intervention problem status.

ABA Design

500

What is it called when any change occurs during the study in the way the dependent variable was measured? 

Instrumentation

500

This is a methodology for describing interventions that is described as technologically sophisticated, time consuming, and difficult to arrange with clients and agency.

videotapes

500
This design is utilized when a client's behavior is too severe to establish a baseline and must begin with an intervention.
