Basic Principles of Single-System Designs
Baselining
From the Case STudy to the the basic single-system design: A-B
100
What question do all single-system designs answer first?
Did the target problem change after the intervention began?
100
The data you collect during __________continue to be collected on the same target and in the same way throughout your intervention program
baseline
100
Name one arrangement for evaluating work on clients from observational only
A-to intervention only

B- to the case study B, in which intervention and observational assessment occur simultaneously.


200
Name one of the  main reasons for using the single-system design?
1. Design encourages practitioners to assess teh case as objectively  as possible, and to montor changes n client targets over time

2. Evaluate whether changes actually have occurred in targeted events.

3. Evaluation extended to whether the practitioners's intervention could be casually linked to these observed changes.

4. Enable practitioners to compare the effectiveness of different interventions.

200
Name one of the two type of baselines.
1. concurrent  (prospective) baseline

2. reconstructed baseline (retrospective) baseline.

200
Name a basic single-system design.
A-B design
300
All single-system designs begin with recording and then simply _________ the changes you make in your interventions in subsequent phases.
reflecting
300
What tools can you use to help determine how long base lining should continues. Name at least two.
utility, stability, and selecting a period of time using several guidelines
300
Name the first of the planned arrangement of baseline and intervention phases
A-B design

Bonus: Name all 4 main reasons for using single-system designs.

1. Design encourages practitioners to assess teh case as objectively as possible, and to montor changes n client targets over time

2. Evaluate whether changes actually have occurred in targeted events.

3. Evaluation extended to whether the practitioners's intervention could be casually linked to these observed changes.

4. Enable practitioners to compare the effectiveness of different interventions.

Bonus: Name both types baselines.

1. concurrent (prospective) baseline

2. reconstructed baseline (retrospective) baseline.

They do not permit planned comparisons among phases of services, but are discussed because they're both historically important as precursor to true evaluation designs ans because they are still commonly used as if they provided objective information. What are they?
