Problem:
If using self-designed survey instruments. Some key elements to consider are:
Must use instruments with sound psychometric (reliability and validity) properties
Variables/Constructs
-Variables: Directly observable (i.e. weight, height)
-Constructs: Mental representations based upon experience (i.e. job satisfaction, commitment)
Do not use self-developed instruments when measuring constructs
You will need to describe each instrument's purpose, intended populations, scales, scoring process, time needed to complete, etc. You will also address the psychometric issues surrounding the instrument, reliability, and validity-this is very important. You will need to report the reliability and validity coefficients. Where possible, include the details of the reliability measures employed (e.g., test-retest, equivalent or alternate form, split-half, and internal consistency). Validity should include content validity, criterion-related validity, and construct validity. State briefly what these measures of validity are and report their Intercorrelation coefficients.
You will need to gain permission from the test publisher to use some instruments.
Question:
