Evidence
The CHIRAL team carefully combs through every reference that cites this instrument and pulls all evidence that relates to the instruments’ validity and reliability. These data are presented in the following table that simply notes the presence or absence of evidence related to that concept, but does not indicate the quality of that evidence. Similarly, if evidence is lacking, that does not necessarily mean the instrument is “less valid,” just that it wasn’t presented in literature. Learn more about this process by viewing the CHIRAL Process and consult the instrument’s Review (next tab), if available, for better insights into the usability of this instrument.

Information in the table is given in four different categories:
  1. General - information about how each article used the instrument:
    • Original development paper - indicates whether in which paper(s) the instrument was developed initially
    • Uses the instrument in data collection - indicates whether an article administered the instrument and collected responses
    • Modified version of existing instrument - indicates whether an article has modified a prior version of this instrument
    • Evaluation of existing instrument - indicates whether an article explicitly provides evidence that attempt to evaluate the performance of the instrument; lack of a checkmark here implies an article that administered the instrument but did not evaluate the instrument itself
  2. Reliability - information about the evidence presented to establish reliability of data generated by the instrument; please see the Glossary for term definitions
  3. Validity - information about the evidence presented to establish reliability of data generated by the instrument; please see the Glossary for term definitions
  4. Other Information - information that may or may not directly relate to the evidence for validity and reliability, but are commonly reported when evaluating instruments; please see the Glossary for term definitions
