, PMHNP Exam Prep 2026-2027: 100 Questions & Answers
Section I: Research Methodology and Evidence-Based Practice
1. Which term describes the process of sharing research findings with stakeholders who
can apply the information in clinical settings?
A. Data analysis
B. Peer review
C. Dissemination
D. Hypothesis testing
Answer: C
Explanation: Dissemination refers to the active process of getting research information out
to those who need to know it, including clinicians, policymakers, patients, and the public.
Effective dissemination strategies include publication in peer-reviewed journals,
presentations at national and local conferences, journal clubs, and community outreach
programs.
2. A researcher concludes there is no difference between treatment groups when an
actual difference exists. Which type of error has occurred?
A. Type I error
B. Type II error
C. Alpha error
D. Sampling error
Answer: B
Explanation: A Type II error (false negative) occurs when the researcher concludes there is
NO difference between groups when a difference actually exists. In contrast, a Type I error
(false positive) occurs when the researcher concludes there IS a difference when none exists.
Type II error is denoted as beta (β) and is inversely related to statistical power.
,3. Which statistical test would be most appropriate for comparing mean depression
scores among three independent treatment groups?
A. T-test
B. Pearson's r
C. ANOVA
D. Chi-square
Answer: C
Explanation: Analysis of Variance (ANOVA) is the appropriate statistical test when
comparing means among three or more independent groups. A t-test is limited to comparing
two groups only. Pearson's r measures correlation between two continuous variables. Chi-
square is used for categorical data analysis.
4. A study demonstrates that a screening tool correctly identifies 90% of patients with
major depressive disorder. This finding represents:
A. Specificity
B. Positive predictive value
C. Sensitivity
D. Reliability
Answer: C
Explanation: Sensitivity is the ability of a test to correctly identify those with the disease
(true positive rate). The mnemonic "Snout" helps recall that sensitivity rules OUT disease
when negative. Specificity (true negative rate) rules IN disease when positive, remembered
by "Spin." Specificity answers: "Of those without the disease, how many tested negative?"
5. In the PICOT framework for developing clinical questions, the "C" represents:
A. Control group
B. Comparison of interest
C. Clinical outcome
D. Cost effectiveness
Answer: B
, Explanation: PICOT is an acronym for Patient population of interest, Intervention of
interest, Comparison of interest, Outcome, and Time. This framework helps clinicians
formulate answerable clinical questions to guide evidence-based practice decisions.
6. A researcher uses naturally occurring groups rather than randomly assigning
subjects. This design is called:
A. Experimental design
B. Quasi-experimental design
C. Case study
D. Correlational design
Answer: B
Explanation: Quasi-experimental research lacks random assignment to groups, instead using
pre-existing or naturally occurring groups. This design is used when random assignment is
impractical or unethical, though it has greater threats to internal validity compared to true
experimental designs.
7. A study measures the direction and strength of the linear relationship between two
continuous variables. Which statistical test is being used?
A. T-test
B. ANOVA
C. Pearson's r
D. Chi-square
Answer: C
Explanation: Pearson's correlation coefficient (r) measures both the direction (positive or
negative) and strength (from -1.0 to +1.0) of the linear relationship between two continuous
variables. Values near ±1.0 indicate strong correlation, while values near 0 indicate no linear
relationship.
8. A p-value of 0.03 in a research study indicates:
A. There is a 3% chance the null hypothesis is true
B. The probability of results occurring by chance alone is 3%
