Question 1

Which of the following statements is true about the term research hierarchy in EBP?
A) Tightly controlled experiments reside at the top, regardless of the EBP question.
B) Qualitative studies are the most likely to reside at the top for most EBP questions.
C) Where a type of study resides on a research hierarchy depends on the type of EBP question being asked.
D) All types of research designs are relevant to all types of EBP questions.

Accepted Answer

The position of a study type in the research hierarchy depends on the specific EBP question being addressed, as different questions require different types of evidence.

Question 2

Which of the following statements is/are true about qualitative studies?
A) They are just as likely to employ tightly controlled, inflexible designs as are quantitative studies.
B) They tend to employ flexible designs and subjective methods-often with small samples of research participants-in seeking to generate tentative new insights, deep understandings, and theoretically rich observations.
C) They are devalued in EBP.
D) They are most applicable when we seek to determine whether a particular intervention is really the cause of a particular outcome.
E) Both b and c are true.

Accepted Answer

Qualitative studies typically use flexible designs and subjective methods to gain deep insights and understandings, often with smaller sample sizes.

Question 3

Which of the following is an EBP question?
A) What type of play therapy is most effective with traumatized children?
B) What client and therapist characteristics best predict the quality of the therapist-client relationship?
C) What is it like to sleep in a shelter for the homeless?
D) What existing measurement instrument is the most valid for diagnosing whether a client has PTSD?
E) All of the above.

Accepted Answer

E

Question 4

Which of the following designs offers the best evidence to
A) A qualitative design.
B) A tightly controlled experimental design.
C) A correlational design.
D) All of the above; they are all equally valuable for this type of EBP question.

Accepted Answer

A tightly controlled experimental design, such as a randomized controlled trial, provides the strongest evidence for establishing cause-and-effect relationships.

Question 5

To infer that an intervention is the real cause of a change:
A) we must make sure that the change preceded the onset of the intervention.
B) it is sufficient to know that the intervention is correlated with the change.
C) we must ascertain whether the change is correlated with the intervention, learn that it did not precede the intervention, and eliminate plausible alternative explanations for the change.
D) rely on studies that avoided the use of random assignment to treatment conditions.

Accepted Answer

To establish causation, it is necessary to show correlation, ensure the change follows the intervention, and rule out other explanations.

Question 6

Systematic reviews and meta-analyses:
A) reside at the top of the evidentiary hierarchy for answering EBP questions about the effectiveness of interventions, programs, or policies.
B) reside below randomized experiments because they take replications into account.
C) are identical, regardless of what statistics they employ.
D) are all unbiased and of equal quality
E) a, c, and d are all true.

Accepted Answer

Systematic reviews and meta-analyses are considered the highest level of evidence in the hierarchy for evaluating the effectiveness of interventions because they synthesize data from multiple studies, providing a comprehensive overview. However, they are not identical as they can use different methodologies and statistical approaches, and their quality can vary.

Question 7

Which of the following statements is/are true about the pursuit of logic and objectivity in research?
A) Some scholars reject the pursuit of a knowable objective reality.
B) Some scholars argue that even though every individual has his or her own subjective take on social reality, it still is worth trying to minimize bias in research.
C) Some scholars have depicted the notion that just because perfect objectivity is an unattainable ideal we should therefore not even try to minimize bias in research as fashionable nonsense.
D) Some scholars have critiqued relativism as logically self-contradictory because if all views of social reality are equally valid, then how can relativists proclaim their view as the most correct one?
E) All of the above.

Accepted Answer

All the statements reflect different scholarly perspectives on the pursuit of logic and objectivity in research, highlighting debates about objectivity, bias, relativism, and the nature of reality.

Question 8

No matter the EBP question, a tightly controlled experimental design will reside atop the research hierarchy.

Accepted Answer

A tightly controlled experimental design, such as a randomized controlled trial, is often considered high in the research hierarchy, but the best design depends on the specific EBP question and context. Other designs may be more appropriate for certain questions.

Question 9

EBP questions should be formulated by researchers, not by practitioners.

Accepted Answer

EBP (Evidence-Based Practice) questions can be formulated by both researchers and practitioners to address clinical or practical issues and improve outcomes.

Question 10

All EBP questions imply making causal inferences.

Accepted Answer

Not all Evidence-Based Practice (EBP) questions are about causal inferences; some may focus on descriptive or diagnostic aspects rather than causality.

Question 11

Qualitative studies tend to employ flexible designs and subjective methods.

Accepted Answer

Qualitative studies focus on understanding human experiences and social phenomena, often using flexible designs and subjective methods like interviews and observations to gather in-depth insights.

Question 12

Different research hierarchies are needed for different types of EBP questions.

Accepted Answer

Different types of evidence-based practice (EBP) questions, such as therapy, diagnosis, prognosis, or etiology, require different research hierarchies to appropriately evaluate and apply the best available evidence.

Question 13

It is possible for qualitative studies to reside at the top of a research hierarchy.

Accepted Answer

Qualitative studies can provide rich and detailed insights into a research topic, and can be used to develop new theories or hypotheses.

Question 14

When seeking evidence about whether a particular intervention-and not some alternative explanation-is the real cause of a particular outcome, experiments are high in the evidentiary hierarchy.

Accepted Answer

Experiments, particularly randomized controlled trials, are considered high in the evidentiary hierarchy because they are designed to establish causality by controlling for alternative explanations and biases.

Question 15

Because of the importance of replication, systematic reviews and meta-analyses reside above experiments on the evidentiary hierarchy for EBP questions about effectiveness.

Accepted Answer

Systematic reviews and meta-analyses synthesize results from multiple studies, providing a higher level of evidence than individual experiments by reducing bias and increasing reliability.
