2. Now that you have read this chapter, as well as a recent journal article on instrument development, consider a construct in psychology that you would like to measure. In one page or so, address the following questions:

A. What construct have you selected and why?

B. Using the Internet and various texts cited in this chapter, find out if there are already instruments measuring the construct you have selected. If so, write down their names.

C. Write five items that could be used to measure your construct. If instruments already exist that measure your construct of interest, then come up with a unique aspect of your instrument (for example, if there are already instruments for adolescents and adults that measure Attitudes Toward the Elderly, then come up with an instrument that measures Children’s Attitudes Toward the Elderly). Your five items should be placed on a Likert-type scale (e.g., a Strongly Agree to Strongly Disagree continuum with a number of choice points).

D. Now that you have five new instrument items, discuss how you would go about establishing evidence for score validity and reliability for this new brief measure.
