About the Validation of this Measure
Country where validated:
Uganda, Norway
Content validity:
Conducted a systematic mapping review of interventions and assessment tools addressing Key Concepts. Authors discovered no instrument that addressed all the Key Concepts or that was suitable as an outcome measure in trials of the IHC learning resources. The authors then developed a database of multiple-choice items that could be used as outcome measures in the two IHC trials in Uganda as well as for other purposes. The Claim Evaluation Tools database includes four or more items that address each of the Key Concepts. These items were then developed in four steps, using qualitative and quantitative methods over a 3-year period.
Reliability notes:
Cronbach's Alpha was >0.70 for all sets with the exception of set 4 which was 0.63. In addition, the Person-Separation Indexes were satisfactory for all sets with the exception of set 4, which had a value of 0.54
