SPIDER framework domains for study inclusion and exclusion criteria.

SPIDER Categories	Inclusion Criteria	Exclusion Criteria
Sample	Studies in English. From any country. From 2003 onward. Focusing on nurses (including baccalaureate-prepared nurses, registered nurses, nurse educators, nurse midwives, advanced practice nurses, specialty practice nurses). Studies can be included if these target participants/respondents are at least an independent subgroup of a larger study and if this is identified. Studies prior to 2018 that were not reported in Skirton et al. [29] or Wright et al. [30].	Studies focusing on: Nursing students. Midwives (without specification of ‘nurse midwives’). ‘Healthcare providers’ with nurses included in that group, without distinguishing nurses as a subgroup in reporting/analysis.
Phenomenon of Interest	Studies focusing on conceptual definitions of the DOI/GGNPS as they relate to nursing and GG (examine at least one of the conceptual domains of interest: knowledge, confidence, attitudes, practices).	Studies focusing on the impact/effect of education interventions in nursing and GG on the conceptual domains.
Design	Primary research studies using any design.	Secondary research, theoretical papers, conference papers, discussion and opinion papers, grey literature.
Evaluation	Studies that examine/measure the GGNPS operational domains of interest as they relate to nursing and GG (studies do not have to specifically include or reference the DOI but must examine the concepts of interest). Qualitative studies, descriptive, quantitative studies (studies that measure at least one of the operational domains of interest).	Studies that evaluate the impact of educational interventions on DOI/GGNPS domains (knowledge, attitudes, confidence, practice).
Research Type	Qualitative, quantitative, or mixed-method primary studies.
