Mod 12 Component Analyses (Ward-Horner & Sturmey)

Question 1

Which of the following are true about component analyses?

They are the same as parametric analyses.
They are conducted to identify the active components of treatment packages that are responsible for behavior change.
They are a systematic analysis of two or more independent variables that comprise a treatment package.
They may enhance the efficiency and social validity of treatment.

Answer 1

They may enhance the efficiency and social validity of treatment.

Question 2

What were the main purposes of this paper?

Introduce a notation system for evaluating the experimental designs of component analyses.
Review the definition of component analysis.
Discuss experimental procedures for performing component analyses.
Review previous studies that have conducted component analyses.

Answer 2

all of the above

Question 3

When considering the experimental design of a component analysis, what should researchers keep in mind?

sequence effects
behavioral effects related to combining different components
additive effects of components
multiplicative or interactive relations among components
necessity and sufficiency of each component

Answer 3

all of the above

Question 4

Which of the following are methods of conducting component analyses using single-subject experimental design?

multi-variable analysis
dropout analysis
single-variable analysis
add-in analysis

Answer 4

dropout analysis

add-in analysis

Question 5

What were the results found for the dropout component analyses?

Ten performed dropout component analyses.
Two of the analyses evaluated whether the necessary components were also sufficient to produce behavior change.
None of the analyses independently evaluated all components.
Three of the analyses evaluated all component combinations.

Answer 5

all of the above

Question 6

What were the results found for the add-in component analyses?

Thirteen of the analyses identified the necessary components.
Two of the analyses independently evaluated all components for at least one participant.
Five of the analyses used multiple baseline design.
Eighteen performed add-in component analyses.

Answer 6

all of the above

Question 7

Which of the following are concerns that arise when comparing groups of single-subject data in which the component of interest is included in the treatment package for one group but not the other?

The logical error of accepting null findings.
The absence of behavior change between groups may indicate a lack of experimental control or insensitive dependent variables of measurement systems.
Variability across participants might restrict conclusions about the active components of the treatment package.
There might be an interaction between the treatment and participant variables.

Answer 7

all of the above

Question 8

What implications might a component analysis have on social validity?

May affect long-term implementations of interventions.
Removing unnecessary components may improve the efficiency and acceptability of a treatment package.
Active components that improve behavior may be different than the components that make the treatment socially acceptable.
It determines if a treatment is socially valid or not.

Answer 8

May affect long-term implementations of interventions.

Removing unnecessary components may improve the efficiency and acceptability of a treatment package.

Active components that improve behavior may be different than the components that make the treatment socially acceptable

Question 9

What were the limitations of this review of literature?

The evaluation of studies in Table 2 did not take into account the purpose of the study.
The range of percentages for agreement between the first author and the second independent rater.
Definitive conclusions about the number of complete component analyses on the basis of the current review are unwarranted.
The way studies identified the components of the treatment packages.

Answer 9
