What is the proper way of carrying out the following validity analysis,
1. Construct validity
2. Concurrent validity
I googled with Wiki and without Wiki. Nit not much satisfactory answer.
But I think some body here in the forum can help me.
If any body has done that pls explain the steps to conduct the analysis.
I don't think there's a quick and easy answer to this question; you're basically asking "how do I establish validity of measures?", which is essentially an entire sub-field of psychometrics. Construct validity is arguably an overarching term for all types of validity, for example. Concurrent validity is a more specific concept; Wikipedia defines it like this: "Concurrent validity is demonstrated where a test correlates well with a measure that has previously been validated."
The way you carry concurrent validity analysis out is then reasonably clear: you administer the measure you're validating to some sample along with a previously "validated" measure of the same construct. You then calculate the correlation between the two: the bigger the better (although there's no firm standard for how large a concurrent validity correlation needs to be to indicate "good enough" validity).
You might need to look at a behavioural science/statistics textbook to give you a bit more of a well-rounded understanding of validity concepts. What sources have you looked at so far?
