Question 1

The only way you will really know the effectiveness of your own service is to engage in evaluative research, evaluating your service with your own clients.

Accepted Answer

Evaluative research is an important part of determining the effectiveness of a service, and engaging in research with your own clients is the best way to get an accurate idea of how well your service is working. Without this type of research, it can be difficult to know whether or not you are making a positive impact on your clients.

Question 2

The research literature on a given theme varies a great deal from study to study in the conclusions that are drawn, and therefore, the review of a single article can be misleading.

Accepted Answer

The research literature on a given theme is often diverse and may not support a single, definitive conclusion. As a result, reviewing a single article may be insufficient to gain a comprehensive understanding of a theme or topic.

Question 3

A literature review does not inform you of the limitations of the intervention or whether it is better than other interventions.

Accepted Answer

A literature review summarizes existing research on a topic, but it does not necessarily provide information on the limitations or comparisons of specific interventions.

Question 4

One of the ways to reduce the filtering of information based on the researcher's bias in setting up the criteria for review is to include only studies that used a randomized control trial in the experimental design.

Accepted Answer

Including only studies that used a randomized control trial in the experimental design helps to reduce researcher bias as the study's participants are randomly assigned to different groups, reducing the likelihood of pre-existing differences between groups that may influence study outcomes.

Question 5

A systematic review is usually conducted by a team of researchers who receive the benefit of ongoing peer review from others.

Accepted Answer

A systematic review is typically conducted by a team of researchers and involves a rigorous, well-defined methodology that is subject to ongoing peer review to ensure the accuracy and validity of the findings.

Question 6

The advantage of the effect size for a review of evidence is that it is a standard measure can be applied regardless of the particular tool used to measure the target behavior.

Accepted Answer

The advantage of effect size is that it is a standardized measure that can be used to compare results from different studies that might have used different outcome measures.
