Q

What are some literature review types?

A

Narrative review - such as the studies we have done for school so far

Systematic review - includes ALL relevant studies

Integrative review - diverse sampling of research to understand a phenomenon (usually includes only 1 specific study type to look for)

Scoping review - maps out the literature on the topic, may be used to identify gaps

concept analysis - exploring a better understanding of a concept

Q

Describe a systematic literature review

A
  • Focus is on a specific research question that is clearly defined
  • Considered a research methodology
  • Needs robust rigor to reduce biases
  • Aim is to seek ALL relevant studies to give most accurate overview of research
  • Includes published and unpublished
  • Rigorous critical appraisal and evaluation of included study quality
  • Often select studies with a specific methodology (i.e. randomized control trials)
  • Probably most complicated review format
  • Purpose
    o Provide evidence as to effect
    o Inform practice or policy
  • Research question
    o Very specific and narrow focus on a single topic
    o Uses the PICO(T) for quantitative or PEO for qualitative

Q

Which types of literature reviews use a critical appraisal

A

Systematic and Integrative

Narrative probably does because we have to appraise it for our papers lol

Scoping doesn’t because its just looking for the amount of literature exists

Q

Describe an integrative literature review

A

Seeks broad, holistic understanding of a phenomenon
o The new conceptualizations are what is important here

Diverse sampling of empirical, theoretical or both
o Systematic only look at a specific type of study (i.e. only RCTs)

Synthesizes literature, draws conclusions

Overview, critique, and gaps in literature

Often contributes to theory development

NOT comprehensive but still considered a type of research review

Role in previously extensively discussed and reviewed topics is:
o Re-examine and critically analyze the literature that has developed around a topic
o Re-conceptualize, as appropriate, the ideas and beliefs that underpin the topic

Role in newer emergent topic is:
o Development of a conceptual model or framework

Purpose
o Develop theoretical frameworks
o Synthesize diverse theoretical and empirical literature
o Gain holistic understanding of phenomenon or problem

Review question
o Broad guiding question about phenomenon of interest
o I.e. How can nursing student anxiety be reduced in the clinical setting without the use of simulation?

Q

Describe a scoping review

A

Does not identify evidence for practice, but rather to map the literature on the topic

Identifies scope of literature that is available on a particular topic or broad research question

Includes qualitative, quantitative, and conceptualizations

Often done when topic is new or diverse

Does not require critical appraisal

Searching may be as comprehensive as for a systematic review
o May determine if a systematic review should be done

Purpose
o Map body of literature
o Identify knowledge gaps
o Curiosity: What is known? How is it explored?
o Systematic review precursor

Review question
o Often follows PCC (Population-concept-context)
o i.e. What is the experience of nursing students with disabilities in clinical?
 Experience is the concept
 Nursing students with disabilities is the population
 In clinical is the context

Q

What type of literature review maps out the literature on a new or diverse topic in order to identify knowledge gaps and is often a systematic review precursor?

A

Scoping review

20
Q

Describe a concept literature review

A
  • A concept of interest to a profession is studied to determine its attributes and characteristics in order to achieve a better understanding of that concept
  • May be done on concepts that vary from person to person like caring, hope etc.
21
Q

What are some literature sources?

A

Database and internet searches - most common

Catalogues - less common with electronic databases, but CINAHL was a catalogue before it’s online form

Grey literature - unpublished, less accessible papers

Textbooks and dictionaries

Manual searches - complements database searches, you use the information you have to find more information like it

22
Q

Why should you use a variety of sources during a literature review?

A

To ensure the research is robust and systematic in nature

23
Q

Describe database and internet searches as sources for literature reviews

A
  • Most common method
  • Databases are compilations of journals, books, dissertations, conferences etc.
  • Memberships are usually needed for full text access
  • Includes CINAHL
  • If using search engines, use many, and remember it can be crap
24
Q

Describe catalogues as sources for literature reviews

A
  • Falling out as they become electronic databases
  • CINAHL was originally a catalogue before it became a database
  • Historical research involving older searchers may still use this as electronic databases usually only have newer studies
25
Q

Describe grey literature as sources for literature reviews

A

Less accessible and may include unpublished dissertations, obscure journals, unpublished reports etc.

Not including these can lead to a publication bias in studies
o Less significant or negative findings may be rejected and not published

26
Q

Describe text books and dictionaries as sources for literature reviews

A
  • May be hardcopy or soft copy
  • It can be >12 months before it is written and published so information may be outdated even at the time of publications
  • Libraries can offer historical books
27
Q

Describe manual searches as sources for literature reviews

A

Used to completement database or other searches and may include:

Ancestry search
o Checking reference list to identify literature not already reviewed

Descendent search
o Other articles that have used a specific work in their citations leading to more works to look at
o Offered by some search engines

Author search – I did this for my last paper lol

Looking through a journal to see if they have other articles, works better for specific things the journal is known for like Arthritis Journal, or Mental Health Journal etc.

28
Q

What is the most common method for identifying literature sources?

A

Database and internet searches

29
Q

Which type of literature sources is less accessible and may include unpublished dissertations, obscure journals, unpublished reports etc.?

A

Grey literature

30
Q

What is an ancestry search in a literature review?

A

Its a type of manual search and involves checking reference list to identify literature not already reviewed

31
Q

What is a descendent search in a literature review?

A

Its a type of manual search and involves looking for other articles that have used a specific work in their citations.

Basically the one we are looking at is the parent and we are looking for its children, studies that used it for a reference :)

32
Q

When performing a systematic literature review, what is important to the search?

A

Remember: Systematic reviews will ROT your brain

Reproducible
 All details of the search are recorded

Objective
 Search terms include variations in terminology
 Avoiding biasing the using exhaustive search terms

Thorough
 Searching more than one database using a combination of text words plus subject headings (when available)
 Using supplementary search methods in addition to database searching

remember to keep notes!!! that way you can document in your paper how you searched :)

33
Q

What are commands that help filter and refine search engine results?

A

Operators

34
Q

How do parentheses work as operators in a database search?

A

o Putting ( and ) around a few key terms will identify them as the same search word
o I.e. (HIV and AIDS)

35
Q

How do Boolean operators work as operators in a database search?

A

o The use of AND, OR, NOT

36
Q

How do truncation operators work as operators in a database search?

A

o Using the derivation (trunk) of a keywork and an asterisk to identify other forms of the word
o I.e. Nurs* so we identify nurse, nursing, nurses etc.

37
Q

How do wildcards work as operators in a database search?

A

? – Using a ? to replace a letter
 I.e. Wom?n so we identify women and woman

  • used in place of a letter that may/may not be there due to alternate spellings
     I.e. an#emia
38
Q

How should someone screen the literature during a literature review?

A

Scan article to see if it meets the criteria for inclusion or exclusion according to the protocol
o There are tools to help including Covidence
o Each stage of the screening should be documented, and the studies to be used can be put into a diagram, but Covidence will make one for you

Independent reviews are required for systematic and scoping reviews

39
Q

What are we assessing for when doing a critical appraisal during a literature review?

A

 Validity
 Reliability
 Applicability – will the results help me/my context?

40
Q

What are the 2 ways to do a data analysis for a systematic literature review?

A

Meta-analysis
* Statistical analysis of combined quantitative studies

Meta-synthesis
* Thematic analysis of combined qualitative studies

41
Q

What is a thematic analysis of combined qualitative studies?

A

A meta-synthesis which is a type of systematic literature review

42
Q

What is a statistical analysis of combined quantitative studies?

A

A

transparent

reproducible

gaps

44
Q

What are some considerations when interpreting the findings of a literature review?

45
Q

What does it mean to disseminate the findings of your literature review? How can this be done?

A
  • Knowledge transfer to peers and interested groups
  • Publications, conferences, presentations, etc.
