Exam 13: Single Case Evaluation Designs

What would you infer from the following graph of the number of temper tantrums in an AB design? Baseline: 15 15 14 14 13 13 12 12 11 11 Intervention: 10 10 9 9 8 8 7 7 6

Ideally,baselines should be extended until a stable trend in the data is evident.

Target problems can be quantified in terms of their

Which of the following procedures for dealing with an unstable baseline might be appropriate in some situations?

Although AB designs offer the least control for history,they are often worth doing.

The ability to construct a retrospective baseline is one of the advantages of using available records.

Suppose you obtained the following results in a multiple baseline design assessing the impact of family therapy on tantrums,chores,and truancy in treating one child and his parents.Which interpretation(s)is(are)plausible? Number of tantrums: : 4 4 4 1: 0 0 0 0 0 0 0 0 Number of chores performed: A2: 3 0 0 3 3 B2: 3 3 3 3 3 3 Number of days truant: A3: 4 4 4 0 0 0 0 B3: 0 0 0 0

The length of the baseline in single-case designs should be

A practitioner tests whether a new technique will be effective in reducing the number of time-outs required in play therapy sessions for children with conduct disorders.In each of the two sessions before implementing the new technique,five time-outs occurred.In each of the two sessions after implementing the new technique,no time-outs occurred.The practitioner should conclude:

Identify three qualitative methods that can be incorporated in single-case evaluation,and discuss the function of each method.

Multiple measurement points during baseline control for statistical regression.

Which of the following is an example of unobtrusive observation?

Identify the major advantages and disadvantages of each of the following single-case designs:a.AB design.b.ABAB design.c.multiple baseline design.

Sometimes it is appropriate to conduct single-case experiments with unstable baselines.

In single-case experiments,direct observation is always better than using self-report scales or available records.

In single-case experiments,maximizing the number of measurement points helps by

Suppose you wish to measure progress in increasing the amount of time a child in institutional care spends studying as an indicator of the effectiveness of your groupwork intervention.Which of the following approaches most likely would be least vulnerable to reactivity problems?

Explain why it is important to obtain a stable baseline,if possible.Explain your answer in connection to threats to internal validity.

Self-monitoring is an example of unobtrusive observation.

Suppose you instruct a couple to have a typical conversation while you observe them in your office.This would be an example of
