A study’s hypothesis that a new surgical approach produces safer outcomes in
immunosuppressed patients is tested in a fourteen-site research study across the
United States. Subjects at all sites are randomly selected and randomly assigned to
experimental versus control groups. What study design is used in this research
project?
Randomized controlled trial
Model testing design
Quasi-experimental design
Dependent
In quantitative research, the independent variable (intervention, treatment, or
experimental variable) is manipulated or varied by the researcher to cause an
effect on the dependent variable. The dependent variable (response or
outcome variable) is measured to examine the effect created by the
independent variable. An independent variable is a stimulus or activity that is
manipulated or varied by the researcher to create an effect on the dependent
variable. A dependent variable is the response behavior or outcome that the
researcher wants to predict or explain. Extraneous variables exist in all
studies and can affect the measurement of study variables and the
relationships among them. Extraneous variables are of primary concern in
quantitative studies, because they can obscure one’s understanding of the
relational or causal dynamics within the studies. Demographic variables are
attributes of the subjects that are measured during the study and used to
describe the sample.
Counterbalanced design
A randomized clinical trial (RCT) contains random assignment to
experimental and clinical groups and very often is multi-site. A fully
randomized design contains both random selection and random assignment.
Quasi-experimental designs facilitate the search for knowledge and
examination of causality in situations in which complete control is not
possible. Such designs lack a control group, or lack random assignment to
group. The model-testing design requires that all variables relevant to the
model be measured, using correlational statistics. A large, heterogeneous
sample is required. Crossover, or counterbalancing, is a strategy designed to

guard against possible erroneous conclusions resulting from carryover
effects. With counterbalancing, subjects are randomly assigned to a specific
sequencing of treatment conditions. This approach distributes the carryover
effects equally throughout all the conditions of the study, thus canceling
them out. To prevent an effect related to time, the same amount of time must
be allotted to each treatment, and the crossover point must be related to time,
not to the condition of the subject.
