NCBTMB Exam Research Literacy and Evidence-Based Practice

Question 1

Evidence-based practice (EBP) in massage therapy is best defined as the integration of:

Accepted Answer

Best available research evidence, the therapist's clinical expertise, and the client's values and preferences

Answer

Evidence-based practice has three pillars: (1) best available research evidence, (2) the practitioner's clinical expertise and judgment, and (3) the client's values, preferences, and goals. All three must be integrated for truly evidence-based clinical decision-making.

Question 2

In a randomized controlled trial (RCT) on massage for neck pain, participants are randomly assigned to massage or a control group. The PRIMARY purpose of randomization is to:

Accepted Answer

Minimize selection bias and balance known and unknown confounding variables between groups

Answer

Randomization distributes both known and unknown confounding variables evenly between groups, so that differences in outcome can be attributed to the intervention rather than pre-existing group differences (selection bias). This is why RCTs are considered a high standard for establishing causation.

Question 3

A study reports that massage reduces anxiety with a p-value of 0.04. What does this p-value indicate?

Accepted Answer

There is a 4% probability that the observed result occurred by chance if there were truly no effect

Answer

A p-value represents the probability of obtaining the observed results (or more extreme) by chance alone, assuming the null hypothesis is true. A p-value of 0.04 means there is a 4% chance the result is due to random variation — below the conventional 0.05 threshold, making it statistically significant.

Question 4

A systematic review differs from a single research study primarily because it:

Accepted Answer

Synthesizes and critically evaluates all available studies on a focused research question using explicit, reproducible methods

Answer

A systematic review uses a pre-defined, transparent methodology to identify, critically appraise, and synthesize all relevant studies on a specific question. This provides broader and more reliable evidence than any single study. When combined with meta-analysis, it sits at the top of most evidence hierarchies.

Question 5

Which of the following represents the LOWEST level of evidence when evaluating whether a massage technique is effective for a specific condition?

Accepted Answer

An expert opinion or anecdotal case report

Answer

Evidence hierarchies rank study designs by their ability to control for bias. Expert opinion and case reports sit at the bottom because they lack controls, randomization, and systematic methodology, making it difficult to attribute outcomes to the intervention. Systematic reviews with meta-analysis provide the highest level of evidence.
