Dear Justin, 

 

Do correct me if I have misunderstood your reply to Marc's question. It does
seem that evidence from a realist synthesis is what you referred to as
"evidence inspired", and that from a realist evaluation is "evidence-based"?
Or perhaps this is regarding inferring evidence from a similar area, versus
one in which there is available evidence that speaks directly to that area.

 

I was reading  this article
<https://onlinelibrary.wiley.com/doi/full/10.1002/cl2.1015>  by Kumah (2019)
and one of the main differences between evidence inspired and evidence based
practice was that the former is more flexible, less hierarchical in its
approach to ranking of evidence, and more integrative of its use of
different kinds of evidence. 

 

I am trying to reconcile this description with your comments - re: evidence
inspired/evidence-based practice as it relates to realist synthesis and
evaluations. I would be grateful if you could explain a bit more. 

 

Thanks, 

Yakubu

Dear Marc,

 

You wrote:

 

What are the ways in which a mechanism can be inferred when the degree of
richness within pieces of evidence is low?

 

Rely on the principles of transferability and transparency. 

 

Transferability: Is there an evidence-based theory in another sector or area
that you can use to support your inference - looking internationally you
will examples of such integration, or maybe not.

 

Transparency: If you can not locate suitable evidence, describe why that is.
One possibility is the fact you may be the first in your field to construct
such as theory. But if that is true, can you interview key stakeholders and
have them adjudicate on your theory. If you are trying to answer this
through synthesis alone, - earmark the theory in 'section for future
research' in which you propose the need for first hand data collection on
the important bits that did not get tested in the synthesis due to lack of
evidence. It may an evidence-inspired theory that over time becomes an
evidence-based theory.

 

Regulation as a pre-condition to integration is a reasonable idea. Keep
building up your thinking around the theory area. The peripheral parts of
your theorizing may end up becoming central over time.

 

Best of luck,

Justin

Dear all,

 

I am currently creating a realist review on integration of chiropractic care
into healthcare systems worldwide. I have a question regarding indirect
evidence and causality. 

 

As part of the review, I am speaking with stakeholders that are
representatives of chiropractic care services in their respective countries
in order to find additional sources of evidence that would not be possible
through an empirical search. As an example, for a country where the
chiropractic profession has not yet obtained regulation, a theory statement
in this context is that there is no integration due to a lack of regulation,
and that by a country having regulation this will improve the chances of
integration. 

 

Could I infer that lack of regulation is a key factor, from a set of
documents showing the struggle of a chiropractic profession to obtain
regulation within a specific country due to political influences but with no
explicit mention of integration? I.e., what is the cut of limit of
inferred/indirect mechanism from a source of evidence? Would I have to
obtain a piece of evidence that directly states this in text, or can it be
inferred from a body of evidence? What are the ways in which a mechanism can
be inferred when the degree of richness within pieces of evidence is low?

 

Kind regards,

 

Marc
