We are conducting a expert panel to analyse the content validity index of a questionnaire. Any content validity index to analyse the content validity?
Dear Daniel,
There are different content validity index. These techniques vary according to data structure, item types and purpose. For example, there are indices developed from Lawshe, Davis, Hambleton and other authors. There are also statistics based on percentage and proportion of concardance among experts. Good luck
Dear Daniel,
As you reached this stage, each concept to be measured should have its own dimensions and/or aspects. Therefore, the experts are required to state whether each item represents/relates to the dimension, is clear, and is important.
Good luck with your research
There is not an index for content validity. But Lawshe technic can be used for this purpose. Decisions are made based on the opinions of subject matter experts. The article is attachment.
And you can use the multidimensional scaling for content validity like Sireci (1998) does.
