Someone who wants to measure affect in a local setting must construct his own instrument since there are few if any such instruments available from outside sources. The Thurstone attitude test constitutes one alternative operational definition of affect which can be used to accomplish this measurement task. There is a large array of specific skills which constitute the ability to construct a valid Thurstone test. Since these skills are not generally available, a training package has been prepared to train the average college graduate to be able to prepare a Thurstone attitude test. Some of these skills involve voluninous arithmetic calculations for which the package provides two alternatives. Our method uses special computation sheets on which the calculations can be done by hand. The other employs data processing techniques making the tasks much easier. Results of a limited tryout (N = 15) are reported. A copy of a Thurstone affective instrument is appended. (Author/CK)
