Exam 15: Selecting a Research Design for a Single Client

What is the data structure for the limited AB single-subject design?

Which of the following single-subject research designs addresses maturation as a threat to internal validity?

Which of the following single-subject research designs fail to address (e.g., control for) maturation as a threat to internal validity?

Consider the following data analysis question: "Are the treatment scores significantly more positive than the baseline scores?" For which research design is this question most relevant?

Both the limited AB and B designs are single-subject research designs that fail to control for either maturation or history as threats to internal validity.

Identify two situations where it would not be appropriate to engage in the statistical analysis of data in single-subject research. In other words, what would be the evidence that statistical analysis would not be appropriate?

One of the single-subject research designs requires one measurement of the client's target behavior before treatment and one measurement of the client's target behavior at the end of the treatment period.

In the label for the single-subject research design, the letter that represents a period of time where clients are being measured on the target behavior but are not getting treatment is/are the letter(s) ______

Answer all of the following questions: (a) Does the AB single-subject research design control for maturation as a threat to internal validity? (b) Explain how it does, or does not? (c) Does the limited AB single-subject design control for maturation as a threat? (d) Explain how it does or does not?

Answer each of the following questions: (a) What is the issue that is being addressed when you engage in the statistical analysis of data? (b) Can you engage in the statistical analysis of data for a single client if you measure the client's target behavior one time before treatment began and one time at the end of the treatment? (c) Explain why your answer to Question b is true or false.

What types of data situations would suggest that the statistical analysis of data is not warranted in single-subject research?

The AB single-subject design controls for maturation as a threat to internal validity.

When you have an erratic baseline, you have a good situation for the statistical analysis of data.

Which single-subject design is considered to be an experimental?

For some research designs, one of the weaknesses of the single-subject research study is ______.

Answer each of the following questions: (a) Which of these single-subject designs is most feasible for the typical social worker in the evaluation of practice: the AB design, the limited AB design, or the ABC design? (b) Explain why this one is most feasible. (c) What is the most important limitation of this design?

Answer each of the following questions: (a) Explain the carryover effect with regard to the use of the single-subject design in evaluative research; (b) Is this effect an advantage or a disadvantage to the use of single-subject designs? (c) Identify one situation where this effect is likely to be present or absent.

If you have a superior research design, you are in a position to argue that it was your treatment, not something else, that was the cause of the measured client growth.

What is the major distinction between the group research design and the single-subject research design?

Suppose you have achieved statistical significance and you are examining the issue of practical significance with the single-subject study. What is the question you must answer?
