Table 2 Summary of validation activities.
Step | Process | Purpose or Validity Type | Results |
|---|---|---|---|
1 | Ranking of implementability of 3 recommendations by experts at COGS | Validity of the construct of implementability | Consistent ranking |
2 | Guideline review with early GLIA versions | To refine GLIA | Demonstrate feasibility of measurement of implementability |
3 | Expert review of GLIA items and dimensions by HL7 experts | Content validity of GLIA | GLIA items rated generally as relevant and clear. Two new items were added, definitions were clarified, and explanatory material was added. |
4 | Review of the recommendations ranked in Step 1 | Construct validity of GLIA | GLIA assessment of these three guidelines was consistent with experts' rankings of implementability (Step 1). Barriers to implementation were explicitly identified. |
