Week 7

Question 1

What is single-case design?

Answer 1

Subjects behaviour is measured over time during a baseline control period.

Question 2

What is reversal design?

Answer 2

Baseline measured -> intervention -> intervention withdrawal

Question 3

What is multiple baseline design?

Answer 3

The effectiveness of the treatment is demonstrated when a behaviour changes only after manipulation is introduced. Intervention in introduced at different times across subjects, behaviour and situations.

Question 4

What is programme evaluation? What phases are there?

Answer 4

Research on programmes that are implemented to achieve some positive effect on a group of individuals.

1. Needs assessment
2. Programme theory
3. Process evaluation
4. Outcome evaluation
5. Efficiency assessment

Question 5

What is a needs assessment?

Answer 5

Are there problems that need to be addressed in a target population?

Question 6

What is Programme theory?

Answer 6

May involve the collaboration of researchers, providers and possible clients to determine that the programme does address the needs of the population in appropriate ways.

Question 7

What is process evaluation?

Answer 7

When programme under way, the researcher monitors it to determine whether it is reaching the target population, attracting enough clients and whether staff are providing planned services.

Question 8

What is outcome evaluation?

Answer 8

Are the intended outcomes being realised? Must devise way of measuring outcome and then study impact of the programme on outcome measure.

Question 9

What is efficiency assessment?

Answer 9

Is the programme worth the resources that it consumes.

Question 10

What is quasi-experimental design?

Answer 10

Allows us to examine the impact of an independent variable on a dependent variable, but causal inference is much more difficult because quasi-experiments lack important features of true experiments.
