What is synthesis?
‘The process or result of building up separate elements, especially ideas, into a connected whole, especially a
theory or system’ (Oxford English Dictionary)
![Page 4: Synthesising qualitative findings](https://reader036.vdocument.in/reader036/viewer/2022062520/56816254550346895dd29da4/html5/thumbnails/4.jpg)
What is synthesis?
“..the product of activity where some set of parts is combined or integrated into a whole…..[synthesis] involves some degree of conceptual innovation, or employment of concepts not found in the characterisation of the parts and a means of creating the
whole”
Strike and Posner (1983)

Synthesis starts with an epistemological assumption
Subjective idealism: there is no shared reality independent of multiple alternative human constructions
Objective idealism: there is a world of collectively shared understandings
Critical realism: knowledge of reality is mediated by our perceptions and beliefs
Scientific realism: it is possible for knowledge to approximate closely an external reality
Spencer et al, 2003

The review method is related to the aim of the review and the literature that exists A synthesis can aim to:
Bring together separate findings into an interpretive explanation that is greater than the sum of the parts (Meta ethnography)
Produce theories or models that are based on phenomena involving processes of contextualised understanding and action (Grounded theory)
Review need for an intervention, it’s appropriateness, acceptability and effectiveness (Thematic analysis)
Enable exploration of study heterogeneity by context, characteristics and findings (Textual narrative synthesis)
Look at how social, historical and ideological contexts influence the knowledge that is produced (Meta-study)
Bring together research of widely different designs and paradigms (Meta-narrative)

Examine the context in which the knowledge was produced (social, political, historical)
De-contextualised because phenomenon has an accepted definition in the literature

Effect size
1. Children were the main reasons to live, fight, get off drugs, care for oneself, and avoid risky behaviors.
19 43%
2. Whether their children were in or out of their care or custody, being a mother was central to women’s lives: a source of self-esteem, strength, normalcy, inspiration, pride, hope, joy, sense of well-being, & sense of self as a whole woman.
15 31%
3. Children were important sources of physical, practical, emotional, and social support, and unconditional love to their mothers, buffering the negative effects of HIV.
7 18%

An ‘interpretive’ synthesis method: meta-ethnography
Similar methods to those employed in the primary research it contains.
Products: new interpretive constructions, ‘translating the studies into one another’ Transferring ideas, concepts and metaphors across studies; Data: interpretations and explanations of original authors; Looking for reciprocal and refutational studies and lines of
argument; Role of quality and sampling varies.
Exact methods vary amongst the small number of studies reported so far

This review was about…
Research question: How do the perceived meanings of medicines affect patients’ medicine taking behaviour and communication with health professionals?
Was not concerned with searching or assessing quality – it is an example of a method of synthesis.
![Page 18: Synthesising qualitative findings](https://reader036.vdocument.in/reader036/viewer/2022062520/56816254550346895dd29da4/html5/thumbnails/18.jpg)
Steps taken in the synthesis The researchers looked across the papers
for common and recurring concepts. Used Schutz’s notion of ‘first- and second-
order constructs. First order: everyday understandings of
ordinary people Second order: constructs of the social sciences
‘Third order interpretations’ were derived from a ‘line of argument’ based on 1st and 2nd order concepts.

Translating studies into one another

Meta-ethnographic synthesisAdapted from Britten et al., 2002
CONCEPTS described in primary studies
Second order interpretations
Third order interpretations
Adherence/compliance:correct and routine medicine takingSelf regulation: problematic adherence; leaving off drugsAversion: eg dislike of taking drugs; harmful side effectsAlternative coping strategies:eg Traditional remedies, self-help
a)Patients conduct cost-benefit analyses: weigh up risks vs benefitsb) Medicine taking influenced by cultural meanings and resources
c)Self regulation includes the use of alternative coping strategies
Sanctions: Drs talk severely about need to take tablets regularly; coercion from significant others, fear of coercion
d) Self regulation is… inhibited by… the threat of social and professional sanctions
e) Self regulation flourishes if sanctions are not severe
Selective disclosure: patients don’t tell Dr of altered doses; manage info to psychiatrists
f) Patients may not articulate views which they do not perceive as medically legitimated
g) Alternative coping strategies are not seen by patients as medically legitimateh) Fear of sanctions and guilt produce selective disclosure

Grounded theory synthesis
Developed by Eaves (2001) by combining steps used by grounded theorists Charmaz, Strauss & Corbin, Chesler)
Used with the aim of developing a substantive theory or model to explain a phenomenon
Starts with In-vivo codes: chunks of text containing the informant’s own words SO
Relies upon articles containing thick descriptions for theory-building

Which approach should you use?
What is the aim of the review? What sort of literature already exists? How well defined are the concepts in the
literature? How contested are the concepts? Is there a
variation in paradigms or definitions or conceptualisations?
What sort of expertise and resources do you have in your review team?
