an attempt to measure reliability of responses
, for example with the goal of detecting defensiveness, malingering, or careless or random responding.
What are the advantages of using an existing measure?
Using an Existing Measure
Among the advantages are that (a)
you save the time and trouble of creating your own
, (b) there is already some evidence that the measure is valid (if it has been used successfully), and (c) your results can more easily be compared with and combined with previous results.
How do you test reliability of a scale?
Once you have created a scale, you should test to see
if it is reliable
; that is, to see if the scale items are internally consistent. The most commonly used test is Cronbach’s alpha coefficient. You can assume reliability if the coefficient is greater than . 7.
