QUIZ 5

effectiveness therapy

T/F: a quantitative systematic reviews of effectiveness include a meta- synthesis

true

When planning a systematic review a preliminary investigation is undertaken to determine whether there have been any reviews already conducted on the topic of interest. What circumstances would warrant another review to be undertaken if one already exists? Select all answers that apply. A:New research has recently been published since the existing review was undertaken B:The review did not follow systematic methods C:The review that exists was published over 10 years ago D:It will be very difficult to justify another systematic review when one has already been completed.

A,B,C

what are the ongoing debates surrounding meta- syntheses? select all that apply A: Whether to exclude low-quality studies B: Whether to include two reviewers for conducting the appraisal of studies C:Whether to integrate studies based in multiple qualitative traditions D:Various typologies and approaches; differing terminology

A.B,D

which activity is not normally undertaken as part of doing a meta- synthesis? A: Obtaining the original data set from primary study researchers B:Searching for and selecting a sample of primary studies C:Evaluating the quality of the primary studies D:Systematically extracting and recording data from the primary studies

A: obtaining the original data set from a primary study researchers

What is true about the researchers conduction meta-syntheses? a: They often conduct original studies on the same topic as the meta-synthesis they are conducting. B:They use only primary studies from peer-reviewed journals in the analysis C: They perform little advance planning, as it is not needed in qualitative research D:They sample primary studies until saturation is achieved

A: they often conduct original studies on the same topic as the meta-synthesis they are conducting

Critical appraisal is necessary in a systematic review because.. select all that apply a: It helps to cut down on the number of research articles to keep. B: It facilitates a deeper knowledge of the included studies C: Combining results of poor quality research may lead to biased or misleading estimates of effectiveness D: It helps establish the methodological quality or risk of bias of included studies

B,C,D

which statement about systematic reviews is true? a: Systematic reviews just another name for a literature review B: All systematic reviews of quantitative studies are meta-analyses C: Systematic reviews follow similar rules as for primary studies D: All systematic reviews of quantitative studies are meta-syntheses

C: systematic reviews follow similar rule as for primary studies

which best characterizes meta-synthesis? A: They are narrative summaries of research findings B: they are similar to concept analyses C: they rely primarily on phenomenological primary studies D: they involves interpretation as well as integration of previous findings

D: they involve interpretation as well as integration of previous findings

T/F: According to sandelowski and Barroso, a meta-summary lays the foundation for meta-analysis

False

T/F: An advantage of meta analysis is that it reduces the risk of a Type 1 error compared to a single study?

False

T/F: a key component of meta-analysis is the calculation of an effect size index

True

to limit the risk of error and bias during study selection a: two independent assessors should be used B: the full-text of all studies/papers without an abstract should be received C: one assessor should be used

a: two independent assessors should be used

which statement is not true? A: Standard meta-analytic procedures cannot be used with qualitative findings B:It is not always appropriate to use meta-analysis to synthesize quantitative findings C:Research synthesis and integration are important primarily to academics and researchers D: A major advantage of meta-analysis is that integration of results can be done objectively

b: research synthesis and integration are important primarily to academics and research
