Data elements

Variable	Format	Description
Article identifiers
First author	Free text	Last name of the article’s first author
Title	Free text	Title of the article
Publication year	Numerical	Year in which the article was published
Article type	Categorical	Whether the article is labeled as a research article or short report by the journal
Primary question: to what extent have the PATH4IR Project’s priority domains, aims, and testable hypotheses been studied in IR to date?
IS	Dichotomous	Whether the study develops or assesses an IS
	Categorical	If yes, whether the implementation strategies of interest are evaluative and iterative, provide interactive assistance, adapt and tailor to context, develop stakeholder interrelationships, train and educate stakeholders, support clinicians, engage consumers, utilize financial strategies, or change infrastructure
	Free text	If yes, lists the IS of interest
HHRO	Dichotomous	Whether the study assesses an HHRO
	Free text	If yes, lists the HHRO of interest
EBMI	Dichotomous	Whether the study assesses an EBMI
	Free text	If yes, lists the EBMI of interest
CRMM	Dichotomous	Whether the study assesses a contextual factor as a moderator or mediator in some relationship
	Categorical	If yes, whether the contextual factors of interest are related to intervention characteristics (e.g., complexity), outer setting (e.g., external policies and incentives), inner setting (e.g., leadership engagement), individual characteristics (e.g., staff perceptions about the intervention), or the implementation process (e.g., extent of planning ahead of implementation)
Path C	Dichotomous	Whether the study assessed the IS ➔ HHRO relationship
Path A	Dichotomous	Whether the study assessed the IS ➔ EBMI relationship
Path B	Dichotomous	Whether the study assessed the EBMI ➔ HHRO relationship
URQ hypothesis	Dichotomous	Whether the study tested a URQ hypothesis
ULQ hypothesis	Dichotomous	Whether the study tested a ULQ hypothesis
LLQ hypothesis	Dichotomous	Whether the study tested an LLQ hypothesis
LRQ hypothesis	Dichotomous	Whether the study tested an LRQ hypothesis
Secondary question: Which other domains have been studied in IR to date?
Implementation outcome	Dichotomous	Whether the study assesses an implementation outcome that is not yet evidence-based
	Categorical	If yes, whether the implementation outcomes of interest are related to acceptability, adoption, appropriateness, feasibility, fidelity, implementation cost, penetration, or sustainability
	Free text	If yes, lists the contextual factors of interest
Context generally	Dichotomous	Whether the study considers the implementation context without assessing it as a moderator or mediator in some relationship
	Categorical	If yes, whether the contextual factors of interest are related to intervention characteristics (e.g., complexity), outer setting (e.g., external policies and incentives), inner setting (e.g., leadership engagement), individual characteristics (e.g., staff perceptions about the intervention), or the implementation process (e.g., extent of planning ahead of implementation)
	Free text	If yes, lists the contextual factors of interest
Other domain	Free text	Lists domains other than IS, HHRO, EBMI, implementation outcomes, CRMM, or context generally that are studied
Secondary question: Which other aims have been studied in IR to date?
Path A-ish	Dichotomous	Whether the study assessed the IS ➔ implementation outcome relationship
Other aim	Free text	Lists relationships other than path C, path A, path A-ish, and path B that are studied
Secondary question: Which other hypotheses have been tested in IR to date?
Other hypothesis	Free text	Lists testable hypotheses other than URQ, ULQ, LLQ, and LRQ that are studied
