Deck 26: Single-Subject Research

Question 1

A multiple-baseline research design across behaviors investigates an individual treatment variable applied sequentially to separate behaviors in a single participant.

Answer 1

True

Question 2

A multiple-baseline research design across settings is a design where individual behaviors are studied in multiple participants within a specified setting of interest.

Answer 2

False

Question 3

A multiple-baseline research design across participants investigates one behavior treated sequentially across matched participants.

Answer 3

True

Question 4

In single-subject designs, dependent variables do not have to be operationally defined due to individuals serving as their own controls.

Question 5

Data collection methods must be both replicable and reliable in order to maintain validity.

Question 6

With social validity in mind, it is possible for an intervention to result in desirable changes in the dependent variable, but still be identified by research participants as being unacceptable.

Question 7

Please match the definition with design the appropriate.

-A design used to compare the effects of intervention and no intervention or to compare the effects of two or more distinct interventions

A) A-B design
B) A-B-A withdrawal design
C) Multiple baseline design
D) Alternative-treatment design

Question 8

Please match the definition with design the appropriate.

-A design that includes a baseline phase and a treatment phase

A) A-B design
B) A-B-A withdrawal design
C) Multiple baseline design
D) Alternative-treatment design

Question 9

Please match the definition with design the appropriate.

-A design that uses repeated measures of at least three baseline conditions that typically are implemented concurrently, with each successive baseline being longer than the previous one

A) A-B design
B) A-B-A withdrawal design
C) Multiple baseline design
D) Alternative-treatment design

Question 10

Please match the definition with design the appropriate.

-A design that consists of a minimum of three phases: baseline, intervention, and repeated baseline

A) A-B design
B) A-B-A withdrawal design
C) Multiple baseline design
D) Alternative-treatment design

Question 11

All of the following describe single-subject research except:

A) It involves in-depth analysis of a single research subject or a small group of subjects considered collectively.
B) Each participant serves as his or her own control.
C) It is a design most commonly employed for experimental trials.
D) There is systematic application, withdrawal, and sometimes variations of the intervention (independent variable).

Question 12

Which of the following would not be a correct consideration in data analysis when using graphs for single-subject studies?

A) Each variable for each participant or system is graphed with the dependent variable on the y-axis and time on the x-axis.
B) When graphing data for one variable for more than one participant, the scale for each graph should be the same to facilitate comparisons across graphs.
C) Vertical lines indicate phase changes, and lines connecting data points reflect consecutive intervals.
D) Equal-interval graphs should be avoided due to their complexity and difficulty being understood.

Question 13

Which of the following would not be a common data collection means?

A) Physiological measures
B) Biological measures
C) Self-report measures
D) Frequency measures

Question 14

Which of the following would not be a method of replication that would help to ensure that findings are generalizable?

A) Replicate the study with other individuals (subjects)
B) Replicate the study in other settings
C) Replicate the study using other therapists/interventionists
D) Replicate the study using alternative means (interventions)
