Question 1

Which of the following research designs contains a control group?
A)Experimental
B)Quasi-experimental
C)Non-experimental
D)Case study

Accepted Answer

Experimental research designs typically include a control group to compare against the experimental group, allowing researchers to determine the effect of the independent variable.

Question 2

When evaluating the design of a research study, we can utilize the hierarchy of evidence. With which of the following factors does the hierarchy rank research designs?
A)Publication date
B)Length of study
C)Bias
D)Number of subjects

Accepted Answer

The hierarchy of evidence ranks research designs based on their susceptibility to bias, with designs less prone to bias (such as randomized controlled trials) considered higher quality evidence than those more susceptible to bias (such as case reports or expert opinion).

Question 3

Which of the following best defines the term "control group"?
A)The group that controls the entire study
B)The group receiving the intervention
C)The group not receiving the intervention
D)The group that reviews the study outcome

Accepted Answer

The control group in a study is the group that does not receive the experimental treatment or intervention, serving as a baseline to compare the effects of the intervention on the experimental group.

Question 4

Which of the following organizations includes the use of evidence-based practice in its "Vision 2020"?
A)Commission on Accreditation of Physical Therapy Education (CAPTE)
B)American Physical Therapy Association (APTA)
C)Federation of State Boards of Physical Therapy (FSBPT)
D)Medicare

Accepted Answer

The American Physical Therapy Association (APTA) includes the use of evidence-based practice in its "Vision 2020". This vision aims to advance physical therapy practice to ensure care is safe, effective, patient-centered, timely, efficient, and equitable, with evidence-based practice being a key component.

Question 5

After reading a patient's evaluation, you determine that exercises to strengthen the vastus medialis muscle would be beneficial. You ask yourself, "What exercises would promote maximum firing of vastus medialis muscle fibers?" This is an example of which of the following steps of evidence-based practice?
A)Ask
B)Acquire
C)Appraise
D)Apply

Accepted Answer

The step described is the "Ask" phase of evidence-based practice, where a specific, answerable question is formulated based on a patient's need or problem.

Question 6

Which of the following is NOT an essential component in the implementation of evidence-based practice?
A)Current research
B)Clinical experience
C)Patient goals
D)Notes from school from 10 years ago

Accepted Answer

Notes from school from 10 years ago are not considered an essential component in the implementation of evidence-based practice. Evidence-based practice relies on the most current research, clinical experience, and patient goals to make informed medical decisions.

Question 7

Which of the following best describes a "peer-reviewed journal"?
A)A journal that your co-worker was able to read first
B)A journal in which the articles have been evaluated for credibility and relevance by experts after publication
C)A journal in which the articles have been evaluated for credibility and relevance by experts prior to publication
D)A journal in which you plan to share your thoughts with the editor

Accepted Answer

Peer-reviewed journals require that articles submitted for publication are reviewed by experts in the field before they are published, to ensure the research is of high quality and credible.

Question 8

While reading an advertisement in the paper, you notice that the local hospital is looking for participants in a research study. They are looking for people who have knee pain. The advertisement states that if the person has had knee surgery of any type within the past six months that they will not be considered for participation. Which of the following is considered the inclusion criteria for this study?
A)Knee pain
B)Knee pain and knee surgery
C)Knee surgery
D)Absence of knee pain and absence of knee surgery

Accepted Answer

The inclusion criteria for the study is having knee pain, as the advertisement is specifically looking for participants who experience this condition.

Question 9

Which of the following best describes the relationship between the number of subjects to the strength of the research study?
A)There is no relationship.
B)The higher the number of subjects, the stronger the study.
C)The lower the number of subjects, the stronger the study.
D)Studies that have subjects also have the least strength.

Accepted Answer

The strength of a research study generally increases with the number of subjects because a larger sample size can provide more reliable and generalizable results, reducing the margin of error and increasing the statistical power of the study.
