Twelve studies (32.4% of 37 studies) validated information from multiple, linked administrative data sources; five of these studies included inpatient records (13.5% of 37 studies) and five included outpatient records as one of the databases.
The registration tables contain the validated information.
The data triangulation (including two survey types, observations and FGDs) allowed us to validate information from one data source against another.
This dyad approach will allow us to validate information from different sources and also to identify divergences and convergences among viewpoints on therapeutic alliance.
Moreover, both qualitative and quantitative data with ocular observations from diverse sources, which permitted for triangulation to validate information collected from various sources for consistency.
Validity ensured by multiple data sources, triangulation, site visits, wide discussions to corroborate and validate information, and an iterative process throughout the evaluation [ 35, 36, 38- 40].
Triangulation of information was used as a tool for testing one source of information against the others, considering that its by-products were as useful as its primary purpose in validating information.
"It's another information source.
Future studies should seek to validate responses further using recorded information sources such as school records.
Specifically it reckons blockchain technology could play a role by, for instance, being combined with the use of "trustworthy electronic identification, authentication and verified pseudonyms" to preserve the integrity of content and validate "information and/or its sources, enable transparency and traceability, and promote trust in news displayed on the Internet".
Future work, currently underway, will validate this source of information against other sources of travel data and will investigate its value to better understand the spread of infectious diseases for disease monitoring and surveillance purposes.
