چکیده انگلیسی

The responses of 2813 individuals to the Personal Globe Inventory (Tracey, 2002) were examined with the goal of developing a shorter, yet valid version of the scale using item response theory to guide the process. A random sample of 1000 individuals was used to select the best items and then the remaining 1813 were used as a validation sample to examine psychometric properties. For items to be included in the shortened form, the option characteristic curves had to conform to theory and there could be no presence of differential item functioning across either gender or ethnicity. The best 80 items were retained forming the PGI-Short. This instrument demonstrated excellent reliability and adherence to a circular model, there was no differential item functioning across either gender or ethnicity. The PGI-Short was supported as an alternative to the fuller version of the PGI.

مقدمه انگلیسی

Interest assessment selection involves a compromise between quality and quantity. There is a need to have the best measures with strong psychometric properties that provide the most information to the user. Typically this means that instruments are quite lengthy as longer tests are generally more reliable. However, lengthy tests are often impractical given situational or client constraints, and can result in random or incomplete responding. Hence selecting an instrument is often a balance of quality with length. The purpose of the current study was to develop a shortened version of the Personal Globe Inventory (Tracey, 2002) using item response theory and examine the abbreviated scale for its psychometric support.
