Question 5

Question 6

A social work student seeks to reduce her own general level of anxiety through self-desensitization.She used the last five weeks of the fall semester for her baseline and the first five weeks of the spring semester for her intervention period.Why is this a problem? What alternative do you propose?

Accepted Answer

The problem with using the last five weeks of the fall semester as a baseline and the first five weeks of the spring semester as the intervention period is that there may be confounding variables that could affect the student's anxiety levels. For example, the student may have different course loads, different stressors, or different social situations during the two time periods, which could impact her anxiety levels independent of any self-desensitization efforts.

An alternative approach would be to use a within-subject design, where the student tracks her anxiety levels over a longer period of time, such as the entire fall semester, and then implements her self-desensitization techniques for a similar length of time in the spring semester. This would allow for a more accurate comparison of her anxiety levels before and after the intervention, while controlling for potential confounding variables. Additionally, the student could also consider using a control group or seeking professional guidance to ensure the effectiveness of her self-desensitization efforts.

Question 7

Which of the following is an example of unobtrusive observation?

C)   Interviews.

Question 8

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

Accepted Answer

A)   enhancing the identification of precipitating conditions during assessment.
B)   enabling us to change the intervention plan at the point at which we see that no progress is occurring.
C)   increasing our ability to pinpoint unlikely coincidences and therefore infer what is causing changes in the dependent variable.
D)   all of these.E) A) and B)
F) A) and C)

Question 9

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

Accepted Answer

A)   Introduce intervention anyway, recognizing that a stable baseline is not feasible.
B)   Delay intervention until the baseline becomes stable.
C)   all of these.D) A) and C)
E) B) and C)

Question 10

If a self-report scale has high reliability and validity in group research,we can assume it will have equally high reliability and validity in single-case experiments.

Accepted Answer

A) True 
 B)False

Question 11

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?

A)   Have the child record the amount of time and report back to you.
B)   Have cottage parents run spot checks in the cottage at different intervals.
C)   Interview the child each day about the time spent studying the previous day.
D)   Show up at the cottage and observe the child yourself for one hour during the same period each day.E) All of the above
F) None of the above B

Question 12

Suppose our research methods cause the client to improve.This would be termed

Accepted Answer

A)   unobtrusive observation.
B)   reactivity.
C)   social-desirability bias.
D)   generalization of effects.E) A) and D)
F) A) and C)

Number of tantrums per day:

Accepted Answer

A)   History could have caused the change.
B)   The intervention may have been effective, but with irreversible effects.
C)   History could have caused the change or the intervention may have been effective, but with irreversible effects.
D)   none of these.E) C) and D)
F) A) and B)

Question 14

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?

Accepted Answer

A)   History could have caused the change.
B)   The intervention may have had generalizable effects.
C)   History could have caused the change or the intervention may have been effective, with generalizable effects.
D)   none of these.E) A) and D)
F) A) and B)

Question 15

If the target problem improves at any point during the intervention phase,it is safe to infer that the intervention is effective.

Accepted Answer

A) True 
 B)False

Question 16

What would you infer from the following graph of the number of temper tantrums in an AB design?
