While Facebook promised that all photos tagged by non-friends would not appear on a user's profile until she or he had reviewed and approved it, in our tests of the tool, we found that when non-friends tagged others in their posts, the tagged user would receive no notification that he had been tagged.
Pre-testing of the tools was undertaken on 30 leaders of YEDF group beneficiaries in Bondo Township before administering the full-scale interview to ensure clarity of the instruments.
Further testing of the tools with clinical outcomes data within large samples may confirm the diagnostic capabilities of the tool and confirm aspects of the criteria.
The data collection tools were developed and standardised for application in the three countries within a standard operating procedure for training of staff, and pilot testing of the tools.
Recommendations for further research and testing of the tools included the involvement of culturally diverse populations [ 21, 33, 36] and the provision of scoring methods and guidelines for interpretation in the evaluation of the scale [ 36].
Their strength is their focus on a specific issue or problem, the establishment of discrete measurement rules, and field testing of the tools for reliability, validity, and utility within a clinical trial environment.
The engineers then launched a test of the tool the next year and "the response was overwhelming," says Facebook.
Further testing of the tool with a larger sample of nurses in other practice contexts is needed.
Later, a second test of the tool, in its enhanced version, was performed with another sample of 64 students in 2013.
After a period of testing of the tool, the evaluation results presented in this paper report that the tool is easy to use, written instructions are helpful for users, the tool is useful for its purposes and provides valuable recommendations.
